Marry the Regent [Time Travel]

Xue Yunzhou had a big belly. Although he was anxious to see He Yuan, he couldn't move fast, so he had to hold his stomach with both hands and try to take a longer step.

In the past, he would never have dreamed that he would have such an image, nor would he have imagined such a day, and he would never have imagined that he would be so excited because of a little dilute sulfuric acid that he wanted to fly.

He Yuan is currently in the meeting hall. There are two rows of civil servants and military generals on the left and right, just like a small imperial court. This is how vassal kings have always been. Except that they belong to the central government in name, there is no big difference from the emperor in essence, only the size of the territory.

Xue Yunzhou saw that they were discussing important matters inside, so he didn't bother him, turned around and went to the side hall. Although the matter he was about to discuss with He Yuan might be several times more important than what was being discussed inside, it was still unknown after all, so he could only hold back and sit quietly. wait.

After He Yuan finished the discussion, he heard that Xue Yunzhou had been waiting inside for nearly half an hour, he was startled, and hurried over to see him.

Xue Yunzhou jumped up from the chair immediately when he heard the familiar footsteps, and called him excitedly: "Second brother!"

He Yuan knew that he was not a patient person, and that he could stay here for such a long time without making a sound, there must be something very important, but after seeing his expression, his tense heartstrings immediately relaxed, and he walked away. Go over and help him sit down.

"Why do you have to wait so long? Go back and say no?"

"No! I'm so excited! Can't wait!" Xue Yunzhou pulled him to sit next to him.

He Yuan thought that Xue Yunzhou was in the same state when discussing the gold mine that night, and subconsciously raised his brows: "What other mines are there?"

"Hahaha, second brother, your imagination is too barren!" Xue Yunzhou laughed a few times, then gradually suppressed his smile, and his expression became a little dignified, "I saw green vitriol oil at the Taoist place today, I remember green vitriol Oil is our modern dilute sulfuric acid, an invention I thought of, but not sure if it would work."

A smile curled up at the corner of He Yuan's mouth: "I have returned all my knowledge of physics and chemistry to the teacher, and I really can't imagine what dilute sulfuric acid can do."

Xue Yunzhou's eyebrows danced brightly: "You guess?"

He Yuan thought about it intently, then sighed: "Say it quickly, don't be fooled."

"Do you still remember when I was in elementary school, you accompanied me to do my homework?"

He Yuan was slightly taken aback. He remembered that he was still in college at that time, and he did have plenty of time to accompany Xue Yunzhou to complete extracurricular homework. He almost remembered everything he had with Xue Yunzhou, and he was naturally impressed by those extracurricular homework. Thinking about it carefully, his eyes suddenly lit up.

Although he was much stronger than Xue Yunzhou in concentration, but at this moment his breath was not stable, he hesitated: "Simple telegram?"

He quickly remembered that the dilute sulfuric acid was used, it was the voltaic battery and the simple telegraph, and the telegraph is the most useful one here, and the power supply, I am afraid, can only use the voltaic battery up.

The technology that has long been eliminated in modern times is a subversive innovation in ancient times. This is indeed shocking news.

Xue Yunzhou rushed over and put his arms around his neck: "That's it! It's the telegram! We are going to be ahead of the times! Scared the enemies to death! Hahahahahaha!"

He Yuan smiled and kissed him on the forehead, pinched the back of his neck, and said something unsightly: "Is there such a technique here?"

Xue Yunzhou's face froze, and he felt powerless for a moment. He rested his head on his shoulder and made a long voice: "Let me get excited for a while!"

He Yuan patted the back of his head: "Okay, you continue."

Xue Yunzhou was even more powerless, he raised his head to look at him, then raised a hand in front of him, and began to snap his fingers.

"With the green vitriol oil, the next step is copper flakes. With the forging technology of this era, it should not be difficult to make a few copper flakes. In addition to copper flakes, zinc flakes are needed. I just don't know if there is any technology for smelting zinc ore in this world. Now, the next step is copper wire, a lot of copper wire."

Although He Yuan has forgotten a lot of knowledge, he still remembers common sense. After thinking about it, he frowned and said, "It should be no problem to apply tung oil for insulation. The difficulty lies in the forging and laying of wires. In this era, everything is done by hand." The production of such a long and thin wire requires a huge amount of engineering, and it is impossible to achieve a completely uniform thickness, which may affect signal transmission. Besides, the copper wire is relatively heavy, which increases the difficulty and the cost is not low. Not only the cost of materials, but also the cost of labor, the artisans who forge the copper wires, the labor to lay the lines."

Xue Yunzhou nodded in agreement, and comforted himself: "As long as you practice more, you should be able to succeed. Another problem is the maintenance of the wires. If they are buried underground, they must be waterproof, moisture-proof and insect-proof, right?"

He Yuan said: "Tao Guan, it's another huge project."

Xue Yunzhou straightened his body: "In the end, there are only zinc flakes left. I haven't heard that the ancients had any utensils made of zinc. Could it be that zinc mines have not been discovered in this era?"

He Yuan shook his head: "I don't know, I will investigate this."

He Yuan's work efficiency is extremely high, and he said that the investigation was done very quickly, and the results were obtained very quickly.

It is true that zinc ore has not been smelted in this era, but zinc ore often coexists with lead ore, that is, lead-zinc ore. Of course, there is no concept of zinc ore here, let alone the term lead-zinc ore. He Yuan also spent a lot of time It took a little effort to reach this conclusion.

After that, He Yuan began to search for excellent craftsmen across the country to prepare the materials needed for laying the lines. Since the telegram is a confidential task, this work was naturally carried out secretly.

And Xue Yunzhou is thinking, if zinc ore cannot be smelted, can silver flakes be used instead?After all, silver is more conductive, so the amount used is not large anyway, and the cost is completely affordable for them.

Just as he was swaying, a chemical formula suddenly flashed across his mind, fleeting like lightning.

He patted himself on the forehead excitedly and annoyed: The days of enjoying the blessings have been too long, and when encountering these basic matters, he wants to find the right person to solve the problem. Obviously, he can handle it easily by himself, so why bother to look far away? !

That night, Xue Yunzhou told He Yuan about his idea: "There is the simplest method, bury the lead-zinc ore in the charcoal pile, and the zinc can be purified after reaction. The specific burial method needs to be tested several times. , after all, I only remember the formula, I haven't really done it."

He Yuan saw that his expression was quite confident, and his confidence in this project had increased a bit, so he nodded in agreement, and said: "Don't do it yourself, let others do it."

Xue Yunzhou laughed at him: "You think I'm stupid? Not to mention that I'm about to give birth, anyway, I'm also a princess, and my status is very noble!"

He Yuan looked at him amusedly.

After Xue Yunzhou finished laughing, he returned to the telegram and said with emotion: "The telegram is easy to do, but to really work, it must be laid everywhere. The project is so huge that I feel a little guilty."

He Yuan looked indifferent: "The greater the investment, the greater the return. Communication in this era basically relies on manpower. The so-called beacon can only be ordered when there is a particularly urgent military situation. Although it is faster than a horse, it is faster after all. But electricity. This investment is very valuable, and its military significance is immeasurable."

Xue Yunzhou was stunned for a while, and looked at him with his face propped up: "Second brother, I think you are becoming more and more self-conscious and imposing as an overlord."

He Yuan looked at him, his eyes gradually moved down to his tall belly, and said seriously: "I was originally a vassal king, without this self-awareness, I only have to wait for death. The emperor of the capital can have a quarrel with Xue Chong, It can be seen that it is not a fuel-efficient lamp. It may be difficult for us to live in a peaceful place. I have you now, and we will soon have our children. Coupled with our current identities, we are no longer a simple family of four. We also have The entire Qingzhou, including all the soldiers and people in Qingzhou, if Qingzhou is here, we are here, and we have no way to be alone."

Xue Yunzhou grinned, lowered his head suddenly, put the top of his head on his chest, and said with a muffled laugh, "Being the overlord is better than being the boss, isn't it?"

He Yuan couldn't laugh or cry: "Almost, it's just a matter of the size of the stage."

Xue Yunzhou put his arms around his waist, pushed his head again, and said happily: "Anyway, to me, being the overlord's man is much more refreshing than being the younger brother of the BOSS, hehehe!"

He Yuan pushed him back a bit, and quickly stabilized his figure, with a soft look in his eyes, raised his hand to lift him up, and kissed him on the lips.

Xue Yunzhou quickly moved the hand around his waist to his back, and tightened his arms.

Next, Xue Yunzhou began to arrange for someone to extract zinc ore for him. He actually wanted to use Taoist Wuchen, but considering that this person is not easy to trust at present, and the telegram is a very confidential task, he immediately dismissed this idea. I just found a few trustworthy people.

After all, with his guidance, even if these people don't know anything, they just need to know how to follow orders, and they don't need any technical content.

There was something to do, time passed quickly, and when Xue Yunzhou was nine months pregnant, a piece of good news came: the zinc mine was finally successfully extracted!

This was the first progress, and it was a good start. Xue Yunzhou was so happy that he immediately arranged for craftsmen to start making copper and zinc sheets.

Seeing that he was panting even after a smile, He Yuan was really terrified, and he was not allowed to ask about this matter again, and said solemnly: "Don't worry about anything now, I will always watch over those things, you just need to rest assured and wait for the birth, everything will wait until the child is born. Let's talk after you've recovered."

Xue Yunzhou cried with a sad face: "I can't help but worry about those things, I... nervous..."

In fact, He Yuan was no less nervous than him. After all, it was a dissection. Even in modern times with advanced medical science, there is no guarantee that it will go smoothly. What's more, in ancient times, Xue Yunzhou still had two in his stomach, so the degree of difficulty skyrocketed.

He had no choice but to give Xue Yunzhou comfort and confidence with a more determined look.

Xue Yunqing ran to him more frequently, and never missed one time every morning and evening, and the palace also made various preparations and began to treat him seriously. Because of He Yuan's solemnity, no one dared to slack off. The atmosphere in Yanwang Mansion is very strange.

On the one hand, it is dignified from top to bottom, and on the other hand, in order not to affect Xue Yunzhou's emotions, everyone must show a relaxed side in front of him.

Xue Yunzhou was naturally unaware of such a weird and contradictory atmosphere because he was only concerned about waiting for the labor.

He has complained to Xue Yunqing more than once: "Didn't you say that it can be brought forward? It's been nine months, why don't you give birth to me?"

Xue Yunqing glanced at him: "Too early is not good, half a month at most."

Counting the time, Xue Yunzhou became even more nervous, trying to divert his attention, and asked, "Has there been a letter from Yan Guanyu? I don't know what happened to him."

Xue Yunqing's face was slightly pale, and he didn't say anything.

Seeing that his expression was wrong, Xue Yunzhou was taken aback for a moment: "He hasn't contacted you?"

Xue Yunqing was slightly awkward, and said coldly: "It's not relative, why did he contact me?"

Xue Yunzhou suppressed a smile and curled his lips: "I will write a letter tonight and ask someone to deliver it to him. I still owe him a big favor. I should have written this letter long ago."

In fact, he felt a little guilty in his heart. He has been busy with the construction of Qingzhou recently, coupled with the limited energy of being pregnant, he really ignored Xue Yunqing.

Although Xue Yunqing himself may not care much about his attention, but the two are cousins ​​after all, and they have been together for so long together, and it is even more difficult in Yushan. He himself is extremely guilty.

The two were talking, when Yu Qing's voice came from outside: "Princess, Song Quan asks to see you."

He Yuan should be out of the palace to be busy with other things at this time. Song Quan came to him to report the matter when he was about to give birth. First, he had already received He Yuan's order, and Xue Yunzhou could completely give orders on his behalf. Second, the matter must be more important Thirdly, it is natural that this matter is not a bad thing, otherwise He Yuan would never allow him to disturb Xue Yunzhou.

Xue Yunzhou quickly called Song Quan in, but Xue Yunqing consciously avoided.

Song Quan saluted and said: "Report to the princess, the matter of the Gao family has been found out."

Xue Yunzhou regained his energy immediately, because this matter was related to Xue Yunqing, he quickly asked Yu Qing to call Xue Yunqing back, and then asked: "How is Gao Ziming's family?"

Xue Yunqing's expression trembled slightly, he raised his head suddenly, and looked straight at Song Quan with anticipation in his eyes.
