Li Shimin

Gongsun Nian nodded repeatedly.

On the side, Fang Xuanling, Changsun Wuji and others also had joyful expressions on their faces, thoughtful.

"Ok?"

Suddenly, Li Shimin and others seemed to hear someone shouting, so they couldn't help but look up.

I vaguely saw that at the end of the same concrete road in front, there was a person shouting at the craftsmen beside him. It looked like Zi Ren!

A trace of curiosity flashed in his eyes.

"Chu Changshi, is a cement road being built over there?"

Before Li Shimin could ask a question, Cheng Zhijie asked curiously.

"Go back to Duke Su, that's right!"

Chu Suiliang hurriedly replied.

"Your Majesty, the cement road is being repaired, can my old Cheng go over and have a look?"

Cheng Zhijie looked happy, said something to Li Shimin, and then dragged Chu Suiliang and ran over there.

"His Majesty?"

Beside him, Li Chongyi, Changsun Wuji and others were also full of anticipation.

"Go, I'll go over and have a look!"

"Yes!"

With that said, the group of people walked towards the place where the road was built.

After walking in, everyone could see a man from Zi, holding an iron gourd-like thing in his hand, shouting loudly.

Around it, a group of craftsmen and servants, just like making mud, mixed a pile of gray soil and some sand with water to mix them evenly.

Afterwards, the two servants pushed a small iron cart, pushed the gray soil, and fell on the road far away.

There, a group of craftsmen were using a scraper to smooth the gray soil, and there were strips of wooden boards on both sides to block it.

"Your Majesty, this gray soil is cement. Mix it with sand and pour it on the road. After it dries, it will be as hard as a boulder. From now on, this cement road will not be afraid of flooding or being crushed by wheels! "

Sun Nian, the general supervisor, quickly explained from the side.

"This thing is so miraculous!"

Li Shimin, Cheng Zhijie and others were shocked.

So like mud, pour the cement on the ground, and when it dries, it will be as hard as a boulder. If it is used to build Datang roads?Just thinking about it, Li Shimin couldn't help but feel excited.

Then, thinking of something, Li Shimin quickly looked at Gongsun Nian: "The general will be a prison, and the same is true for building a house?"

"Return to Your Majesty, building a house is different!"

Gongsun Nian quickly said: "Your Majesty, please come with me. The construction of a house also requires steel and small stones. The house that is poured is hundreds of times stronger than the road!"

"Harder than the road?"

Li Shimin, Cheng Zhijie and others were full of anticipation.

While speaking, Gongsun Nian had brought Li Shimin and Cheng Zhijie to a huge pit!

Under the deep pit, there are more than 300 craftsmen, with more than 500 laborers, doing work in an orderly manner that Li Shimin and others can't understand!

……

Chapter 219 Li Xuan: Someone wants to use a crossbow to shoot the king's warehouse?

In the deep pit about half a foot high, teams of craftsmen are binding steel bars, and every ten feet, they tie up a steel column that is as wide as a person's body.Then, seal the reinforced columns with a piece of board, and pour cement mixed with small stones into it.

At the bottom of the deep pit, it seems that there are also steel bars tied flatly, and there are also strong laborers pushing small carts, dumping stones mixed with cement into it.

"Please look, Your Majesty, these cement mixed with small stones are the concrete used to build houses!"

Gongsun Nian pointed to the dark gray concrete pillars in the deep pit, and introduced: "Pour concrete and steel bars together, and after it dries, it will be harder than boulders. It cannot be damaged!"

"General Prisoner, you said that those iron-like things are steel bars?"

Li Shimin frowned and asked.

"Return to Your Majesty, it is the steel bar!"

As he spoke, Gongsun Nian quickly walked aside, picked up a steel bar from a pile, put it in front of Li Shimin, and explained: "Please look, Your Majesty, a steel bar is a steel bar forged from fine steel, which is not easy to corrode and is very hard. , used to build a house, can make the house immortal for a thousand years!"

Seeing this, Cheng Zhijie and others on the side also picked up one with curiosity on their faces, and their eyes became brighter the more they looked.

However, after hearing Gongsun Nian's explanation, everyone's eyes were filled with anger.

"You old guy, that's fine steel. Do you know how important fine steel is? These three steel bars can forge a hundred-refined steel knife. So much fine steel can be given to the old man Youwu Weierlang, all of you. Replace with a hundred steel-making knives!

And you old man, what is your intention to use such treasures to build a house? "

Cheng Zhijie stared at Gongsun Nian fiercely, thinking that if you are not satisfied with the explanation to the old man, he will beat you up.

"Your Majesty, please forgive me, Duke Su, don't be annoyed, I have no choice but to serve as an official!"

Gongsun Nian quickly took a step back, smiling all over his face.

For this nightmare of the entire civil service system, he is a young general as a prisoner, and he cannot be provoked.

"The old man wants to see how you sophistry?"

Cheng Zhijie was still staring at Gongsun Nian viciously.

"Your Majesty, Su Guogong, this steel bar is the steel bar of His Royal Highness King Jin. If King Jin wants to use this kind of treasure to build a house, there is nothing I can do about it!" Gongsun Nian looked bitter.

"King Jin?"

Hearing this, Cheng Zhijie's expression froze and he remained silent.

Meanwhile, Li Shimin, Changsun Wuji and others' complexions quickly turned from cloudy to sunny.

"The king of Jin must have built a house with steel bars, and the supervisor must fully cooperate!"

Gongsun Nian was taken aback for a moment, and quickly said firmly, "Please rest assured, Your Majesty, I will definitely do my best to build a house for King Jin with steel bars!"

"Ok!"

Li Shimin nodded in satisfaction.

After recovering, Cheng Zhijie glared at Gongsun Nian again, pointed to the concrete pillars in the pit, and asked, "You will be the prisoner, you said that the house made of concrete and steel bars is equipped with carts and crossbows?" Can't break it?"

"Back to Duke Su, the officials dare not deceive His Majesty!"

Gongsun Nian said quickly, his eyes full of confidence.

"Ok?"

Hearing this, Shimin and Li Chongyijie were all surprised.

"If your Majesty doesn't believe it, can you test it directly?" Gongsun Nian said.

"Your Majesty, Lao Cheng is going to dispatch a crossbow right now?"

Cheng Zhijie hastily shouted.

"Your Majesty, I agree with Su Guogong's words!" Li Chongyi also hurriedly cupped his hands and said.

This time, Li Shimin's eyes were also full of emotion.

As a war madman, he also had some disbelief that there was a wall that even a crossbow could not shoot through!

"Is there any concrete walls or pillars for the prison?" Li Shimin asked.

"Return to Your Majesty, there are concrete houses that have been built over the factory!" Gongsun Nian quickly pointed to a row of square gray houses in the distance, and said.

At this time of year, the whole land is still gray. Without Gongsun Nian's guidance, Li Shimin and Cheng Zhijie wouldn't have noticed it unless they looked carefully.

"Your Majesty, my old Cheng is going to adjust the crossbow now?" Cheng Zhijie asked for instructions.

"Ok!"

Li Shimin nodded slightly, and Cheng Zhijie ran into the city excitedly.

Afterwards, Gongsun Nian took Li Shimin and others to observe the construction of the foundation of the house again, and then walked towards the concrete houses.

After entering, Li Shimin and others discovered that this concrete house was as big as his palace.

It's just that the whole thing is gray and black, just like Cheng Zhijie, ugly and black.

"Your Majesty, these houses are built for warehouses, and they are filled with steel bars that are not used up on weekdays, or small carts and some tools used by craftsmen.

Store it here at night and take it out during the day!The whole house is made of concrete, and the crossbow is impenetrable. At night, only one person is required to guard it. Not to mention the storage of tools, even the storage of copper coins and silk is safe! "

Gongsun Nian introduced confidently.

Hearing this, Li Shimin and Li Chongyi couldn't bear it, they stepped forward and kicked the wall hard.

Immediately, he quickly took a few steps back expressionlessly.

Then, in less than a while.

Cheng Zhijie came hurriedly with a group of soldiers, pulling a chariot crossbow, and parked the chariot crossbow two hundred steps away from the house.

"Your Majesty, please stay away!"

After assembling the crossbow, Cheng Zhijie shouted excitedly.

"This old thief..."

Li Shimin yelled helplessly, but quickly dodged aside.

Not far from them, there were also a group of people watching curiously.

"Master, this is a chariot crossbow. It is the most powerful offensive weapon of the Tang Dynasty. It is also called a ballista. It can attack cities and fortresses, and it is invincible. Normally, the range is about [-] steps. Su Guogong sent it Placed two hundred steps away, the power of the crossbow can be maximized, and it is also the most accurate distance..."

Li Baoding explained to Li Xuan beside him with a serious face, "Su Guogong used this crossbow to shoot at the wall of the warehouse, and the wall of the warehouse may not be able to resist it!"

Behind them, Li Chengqian and Cheng Chusi, although their eyes were fixed on the crossbow and the warehouse in the distance, their faces were full of embarrassment.

This is Lijiazhuang, Master's chassis, you guys have come to Lijiazhuang, just wander around, why did you transfer the crossbow from the city, and pointed it at the warehouse on the master's construction site.

Even if you want to rob Master's warehouse, you guys should say hello to Master!

Don't talk about this side, wait until Li Shimin, Changsun Wuji and others all retreat to the side.

Cheng Zhijie commanded the soldiers beside him, put a huge arrow three feet five inches long and five inches thick on the crossbow path, pointed it at the concrete wall in front, and gave an order.

With a 'boom' sound, the huge arrow hit the wall, and then bounced directly one foot away.

"This?"

Seeing this, Cheng Zhijie, Li Shimin and the others couldn't help but widen their eyes with shock.

"It actually blocked it!"

Cheng Zhijie yelled in disbelief, and quickly ran towards the wall.

After looking for the point where the giant arrow hit, I looked for a long while, and remained silent for a long time.

"It's really like the general prisoner said, even the crossbow can't do anything to this wall!"

And Li Shimin, Changsun Wuji and others who came over from the side also stared wide-eyed and took a deep breath.

Just when they were stunned, there was a chuckle from behind them.

"How, is the wall made of steel and concrete still strong?"

"It goes without saying that even a crossbow can't pierce it..."

Cheng Zhijie opened his mouth and replied.

However, before he finished speaking, he froze in place.

Turning his head slowly, his eyes narrowed, his face was stiff, and he quickly said with a sneer: "I didn't expect His Royal Highness King Jin to come too!"

……

Chapter 220 Your Majesty, You Must Get the Cement!

"Everyone has used the crossbow to shoot at the king's storeroom. I should come and take a look at what I say!"

Li Xuan said with a flat face.
