Marry the Regent [Time Travel]

Tuli is a nation on horseback. Many factors such as terrain, climate, terrain, distance, and living habits all determine that their combat methods rely on cavalry. The number of times of the city is still very small, and their siege techniques have always been relatively primitive, which is why Xue Yunzhou and the generals have full confidence in defending the city.

But now Tuli actually has a siege engine, and this siege engine is so strong that even Qingzhou's experienced generals are afraid, this is really unexpected!

It’s not that one’s own side carelessly underestimates the enemy. It is an indisputable fact that the Tuli people lack siege technology. The principle of siege vehicles is very simple, but if they want to work, they often have complex structures and many organs. Emphasis on education, but still far from the Central Plains, not only the lack of skilled craftsmen, but also the lack of related materials and resources, it is not easy for the Tuli people to build a decent siege engine by themselves.

What's more, the secret agents of Prince Yan's Mansion have been paying attention to the movement there. If they really build a siege vehicle, it is impossible to hide such a big movement.

Xue Yunzhou stepped up to the gate tower full of shock and doubts. At this time, the sky was gray and there was some light. He frowned and looked down. Although he was mentally prepared, he was still taken aback by the huge monster. Jump.

The entire Qingzhou does not have such a big siege engine, and if Qingzhou does not have it, then the imperial court does not have one. In terms of size alone, there is no such a large siege engine in the entire Central Plains. In terms of sturdiness, this one is also quite impressive. Precise... Xue Yunzhou squinted his eyes to observe its structure through the brighter and brighter sky... There was a "thump" in his heart, and he felt even worse.

Upon closer inspection of this siege engine, there was a faint sense of familiarity.

At this time, the city wall has become a mess, and a group of soldiers are busy trying to consolidate the city gate under the city wall. Fortunately, after Xue Yunzhou appeared, everyone was reassured. Coupled with the scolding and orders of the generals, the scene Gradually get under control, become tense and methodical.

There was a solid roof above the siege vehicle, and the Tuli soldiers pushing the vehicle were hiding under the roof. At this time, the arrows had no effect, and only the trebuchet dropped huge stones over and over again. The water droplets could still penetrate the stone, and the huge stone After smashing down one by one, sooner or later a hole will come out, but the siege engine has already arrived at the bottom of the city, and the pointed logs covered with copper skin are pounding heavily on the city gate again and again. It is still unknown which side will not be able to hold on first.

Xue Yunzhou didn't care to think about where the familiar feeling of the siege engine came from. Seeing that the city gate was getting more and more fragile, he was so anxious that his throat was full of smoke, and he kept thinking about the countermeasures.

Not long after, the sky was bright and the city gates had been further consolidated, but Tuli's siege vehicles kept hitting them over and over again like tirelessly. After a while, the thick layer of ice on the city gates had been completely peeled off under the impact, and the gaps between the city gates were also getting bigger and bigger under the impact, and there was a faint tendency to be unable to hold it.

General Li and General Zhao roared to give orders to their subordinates, but this siege vehicle was really ingeniously built. Not only was the roof covered with a thick layer of iron, but the body below was also poured with mud. Suddenly, the tuli soldier holding the log hid under the car unscathed.

If this continues, Qingzhou City will soon be finished!

The people in the city were already weeping loudly, and the blood-stained faces of the soldiers gradually turned gray. The Turi people have always been cruel and heartless. Once they were allowed to attack, the consequences would be disastrous.

The snow had already stopped, and there were even a few rays of sunlight in the clouds. Xue Yunzhou looked at the cloud with gold borders, and suddenly a flash of inspiration flashed in his mind. dilute sulfuric acid.

Dilute sulfuric acid!

Xue Yunzhou's spirit was lifted, and he turned around and shouted: "Yu Qing, go to Taoist priest Wuchen quickly! Ask him to prepare dilute sulfuric acid, the more the better!" He shouted to General Li who was not far away, "General Li, quickly arrange Thirty or forty people followed Yu Qing!"

General Li is a military commander after all, and he doesn't know much about Taoist Wuchen's position in the Yan Palace. Hearing Xue Yunzhou mention this person at this moment, he couldn't help frowning and said in puzzlement: "Now is the critical period. What effect?"

In the eyes of the ancients, once a Taoist priest gets along with the rich and powerful, the role they can play is nothing more than refining alchemy and weaving a dream of longevity. Although General Li knew about the gold mining in the Yanwang Mansion, he didn't know how this gold mine was related to other gold mines. The mine is completely different, and I don't know that if there is no Daoist Wuchen, what is mined from this mine is just waste rock.

Xue Yunzhou said anxiously: "Master Wuchen can break the siege vehicles, you arrange people to go first, and I will explain to you slowly."

Speaking of this, General Li had no choice but to follow Xue Yunzhou's order to arrange it.

Xue Yunzhou squinted his eyes to look at the situation below. While worrying that the city gate might be breached at any time, he explained to General Li: "Master Wuchen can extract dilute sulfuric acid, which is green vitriol oil, which can dissolve iron. , once the iron on the roof of the siege engine is melted, they will lose their shelter and it will be easy to deal with them."

General Li was taken aback, his eyes widened in disbelief: "Is there such a thing? Can this iron be melted without high temperature and fire?"

"Melting" and "melting" have different pronunciations and different meanings.

War in the era of cold weapons has always remained at the physical level. These chemical changes are quite shocking to General Li. He immediately thought of the key point and asked solemnly: "In this world, who else can refine green vitriol?" Oil?"

Xue Yunzhou glanced at him and saw that his worry was palpable, knowing that he was afraid that others would use the same method to deal with him, so he said in a firm tone: "Maybe there are other Taoist priests who can refine green vitriol oil, but this green vitriol oil is also For those who are particular, those that are too thick, too weak, or mixed with impurities are not suitable. Only those who can refine the purest green vitriol oil with the right concentration can only be those who know how to use this green vitriol oil. I."

General Li was in awe when he heard this, and he no longer dared to underestimate Daoist Wuchen. As for Xue Yunzhou, he had already admired this princess who had all kinds of weird ideas, and it seemed that it was not surprising to add another weirder one. .

If green vitriol oil can really play a vital role... General Li's blood boils when he thinks about it.

"On the battlefield, green vitriol oil is only a small matter, but it is really powerful..." Xue Yunzhou stopped talking as he spoke, thinking of He Yuan's most important research on firearms, his heart ached again.

General Li, however, was aroused by his curiosity and thirst for knowledge, and hurriedly asked, "What is it?"

Xue Yunzhou clenched his hands tightly, his eyes couldn't hide the pain, he hurriedly lowered his eyes and took a deep breath, and looked up again with his usual expression: "It's nothing, we need to improve, it won't be too late to announce the results, it's a bit early to say now."

At that time, gunpowder was only used in fireworks and firecrackers. To exert its power on the battlefield, the most important thing was the ratio of ingredients. At the same time, skilled craftsmen were arranged to study the carrier of gunpowder. Before this war, the research had already shown signs of success, but He Yuan suddenly had an accident, and never... never saw the results behind...

General Li heard that the information revealed in his words was very important. Although he wanted to ask more carefully, but seeing that his complexion was really bad, he knew that he was hurting for the prince again, so he stopped talking and said nothing more at this time. The battle situation is tense, and it is not the time to ask carefully.

After recovering, Xue Yunzhou rubbed his face, thought about the tactics for a while, and then ordered people to find enough large wooden boards, and asked them to join the large wooden boards together to form a tall quadrangular frame, and punch holes in the frame A rope is tied, and a strong wooden pole is carried on the rope.

As soon as the box was ready, Yu Qing's voice came from afar: "Dodge and dodge! The military situation is urgent!"

Xue Yunzhou followed the prestige and saw a row of soldiers driving a carriage towards the gate of the city under Yu Qing's path. A large tank was placed on the carriage, and the mouth of the tank was tightly covered with a lid, although the inside could not be seen. Things, from Yu Qing's passionate appearance, one can also guess that Taoist Wu Chen's mission was completed well.

Xue Yunzhou's spirit was lifted, and he raised his hand to signal to Yu Qing to let them lift up the big vat.

There were many soldiers at the gate tower, and everyone worked together to lift up the vats one by one with ease. Xue Yunzhou saw that the soldiers who followed Yu Qing back and forth all had leather gloves on their hands, and even the soldiers who joined the vat carrying team later were also Yu Qing handed out the gloves, knowing that it was the order of Taoist priest Wuchen, but he neglected these details in a hurry, and couldn't help being more satisfied with Taoist priest Wuchen.

Yu Qing ran up and said, "Daoist Wuchen said that these are all accumulated from alchemy in the past, and there are only so many ready-made alchemy. Whether it is enough or not, he has already started to practice again, but I don't know if there will be time to use it. ."

Xue Yunzhou waved: "I'll talk about whether it's enough or not, first lift the tank here! Be careful, don't splash on yourself."

After all the big vats were lifted up, the city gate was already crumbling, and the situation became more urgent.

Xue Yunzhou ordered solemnly: "Put down the boards! Surround the siege vehicles!"

The soldiers who had already prepared immediately lowered the planks along the city wall.

In order to increase the force of hitting the city gate, the siege vehicle kept a certain distance from the city gate, and this caused the vehicle body to stop just a little outside the city wall, neither far nor close, and the soldiers on the tower used wooden poles Pick up the wooden frame with the rope, and put it down at the position of the siege vehicle. Because the size and distance are calculated, the wooden frame falls to the ground, just falling around the siege vehicle. In order to prevent the wooden frame from being hit by the siege vehicle, Bad, the side next to the city gate has a gap for the battalion, and the entire wooden frame is next to the city wall, tightly surrounding the siege vehicles in the middle.

The Tuli soldiers in the siege vehicle were confused by this sudden move. No one knew what the purpose of the wooden frame dropped from the sky was, but they were surrounded, and suddenly felt a sense of crisis that they were about to be caught. Someone rushed out and wanted to destroy the plank.

Xue Yunzhou had expected it a long time ago, and immediately ordered: "Shoot the arrow!"

Several sharp arrows roared down with the sound of the wind, and the Tuli soldiers who were exposed outside the protection range of the siege vehicles immediately screamed and died.

Xue Yunzhou ordered again: "Pour the contents of the tank down! Be careful not to splash on your body!"

Although the soldiers didn't know what kind of miraculous thing was in the vat, seeing Xue Yunzhou's serious expression, none of them dared to be careless, so they carefully lifted the lid and tilted the vat.

Large flakes of green alum oil poured down like a torrential downpour, and just poured into the wooden frame. Without waiting for Xue Yunzhou's order, the second vat of liquid followed closely, followed by the third vat, and the fourth vat...

Panic screams sounded outside the city gate, and the soldiers on the tower changed their colors in horror. Thinking that the screams came from the enemy, they immediately cheered up, and poured all the remaining cylinders of liquid into them vigorously.

At first, there were endless screams, and people kept running out from under the siege vehicles, trying to escape by climbing the wooden frame. Later, the liquid in the wooden frame gradually filled up. If they didn't climb to the top of the siege vehicle, they were shot and killed one by one by Qingzhou soldiers on the city tower. As for the Tuli soldiers who came to the rescue from a distance, once they came into range, they would also be unable to escape the pursuit of arrows.

Xue Yunzhou closed his eyes uncomfortably. After all, he is a modern person. Using this kind of method always feels too vicious, but after all, it is his own order. Thinking about it, he feels hypocritical. Fortunately, what is poured here is dilute sulfuric acid after all, far from concentrated Sulfuric acid is so terrifying, although the skin will feel burning pain when it is contaminated with this acid, but most tuli soldiers did not die from dilute sulfuric acid, but from arrows, which seems to be more acceptable to him psychologically .

The siege engine had already stopped hitting the city gate, and not long after, the tuli soldiers were silent, and there was a dead silence under the city gate, and the soldiers on the tower looked at each other with lingering fear.

General Li laughed loudly: "As expected, as the princess said, the treasure sent by Daoist Wuchen is the key to defeating the enemy!"

He didn't say the words "green vitriol oil", because he was afraid that someone with a heart would listen to him, and he was afraid that this effective way to deal with the enemy would be learned by others.

Seeing that the Tuli soldiers were defeated, the surrounding soldiers were greatly encouraged and cheered in unison.

Xue Yunzhou looked down, and the liquid in the wooden frame was gradually reduced due to the seepage of the soil. Fortunately, the amount poured down was enough, and the speed of penetration was not as fast as the speed of dissolution. He stared at the shadowy ceiling that began to dissolve. , knowing that his strategy had worked, he breathed a sigh of relief, and then said in a calm voice, "It's not over yet."

Everyone was puzzled, and hurriedly followed his line of sight. After a while, a burst of breathing sounded around him.

"Every day... oh my god! The roof made of thick iron has melted!"

With a sound of "buzz", the pot exploded on the city tower, and everyone showed horror. They looked at Xue Yunzhou again, and suddenly there was more awe in their eyes. They only thought that this weird water was mixed with some kind of poison. It was used to deal with Tuli soldiers, but now I know that its ultimate goal is actually a siege engine!

This siege engine, which took an untold amount of manpower, material and financial resources, was about to fall apart in an instant, it was so crisp and neat!Even General Li, who had already prepared mentally in advance, also showed shock.

Xue Yunzhou looked at the wooden structure of the siege vehicle slowly exposed after the hard iron melted, and looked at the Tuli army in the distance who did not dare to rush forward any more, and even retreated with gold. Everyone can rest for a while, and when they exit the attack range, we will open the city gate and drag the siege vehicle in." After thinking for a while, he said in a low voice, "Forget it, that thing can't be used, wait for the water to come in." Once volatilized, the remaining dilute sulfuric acid is estimated to turn into concentrated sulfuric acid, and once the wooden frame is carbonized, it will also be destroyed."

The people around were naturally confused, Xue Yunzhou was just talking to himself, and then he raised his voice and said: "The siege engine is placed there, it will fall apart on its own, if it is really an eyesore, just burn it with a torch gone."

Although everyone didn't understand the principle of this, they could find an explanation for themselves: Iron can be dissolved, so isn't wood a piece of cake?

So no one was surprised to hear that the siege engine would fall apart.

After another victory, the soldiers could finally rest, but Xue Yunzhou still stood there, frowning in thought.

At this moment, he relaxed and his mind cleared up a bit. He finally remembered the military engineering atlas he had seen at He Yuan's place. There were all kinds of siege vehicles on it, and the ones used by the Tuli army today The siege engine is a brand new style that combines the advantages of the various siege vehicles in the atlas into one.

In other words, with the brains and resources of the Tuli people, how could it be possible to build such an incredible project? It turned out that there was an insider, and someone leaked the blueprints. The talents and materials needed have also flowed out. Thinking more deeply, the spies did not find any clues that Tuli had built a siege vehicle. Could it be that someone from the Central Plains built a ready-made one and sent it to Tuli directly in a disguise? past?

With this thought, there was a layer of cold sweat behind it, as if this war had been planned a long time ago.

But He Yuan kept the blueprints in He Yuan's private possession all the time, and no one has seen them except him, so it cannot be leaked by Prince Yan's Mansion. He remembers that He Yuan said that another copy of the blueprints is in the palace, which is a secret If it is necessary, it is possible that the people in the palace leaked the secret.

People in the palace, who has the right to see the blueprint, and who has the right to think about treason?Xue Yunzhou racked his brains and couldn't think of a suitable suspect, and the more he thought about it, the more he felt a headache.

Yu Qing said softly at the side: "Princess, the Tuli army has retreated, you haven't closed your eyes for several days and nights, and you are hungry, you should go back and rest for a while."

Xue Yunzhou nodded casually: "Okay."

As soon as the words fell, there was a whirl of dizziness. He hurriedly leaned on the wall to close his eyes and slowly opened them again. After all, he couldn't bear the exhaustion. His legs softened and he passed out amidst Yu Qing's exclamation.
