For the next two days, Ren Baqian went to school during the day and spent the afternoon at the Ministry of Works. He discussed the next two important issues with Tong Zhengye, which were the blast furnace and the steel injection method.
The blast furnace used was similar to the blast furnace used in the Song Dynasty. At this time, the blast furnace used was very similar to the modern blast furnace, and it used charcoal instead of coal, which was more suitable for the current Great Xia.
However, the lower part was a hydraulic windmill. The wooden wheels were driven by water, and the water impacted the wooden wheels to rotate. Then, the windmill was opened and closed continuously through the axles, tension rods, and other mechanical transmission devices. The wind was stronger, the continuity was better, and the flames were more intense.
This method made it easier to obtain pig iron and wrought iron, and it could be produced continuously. The molten iron flowed directly from the side without opening the furnace, and iron ore was added to the top.
This alone saved a lot of manpower and resources.
The next step was to use the steel injection method to hammer pig iron and wrought iron together, causing the carbon to penetrate each other to form steel. This method could increase the speed of turning iron into steel by several times. Furthermore, there was no need for craftsmen to forge the steel. This process could be done with a hydraulic forging machine, and the craftsmen only needed to do the last part.
With this process, the speed of forging iron and steel in Dayao could be increased by at least ten times.
The next step was to slowly develop. After all, there were many good things that couldn't be produced with Dayao's production level.
"See? The water flows down here, washes the wooden wheels, and the wooden wheels move the tension rods. Then, this hammer will automatically hammer down like this … "Ren Baqian used a small model to explain to everyone. This model was made overnight by the craftsmen over the past two days.
A small wooden wheel was placed above a wooden trough. When water was poured from the trough, the wooden wheel would rotate with the flow of the water, completing the entire process that Ren Baqian explained.
"I see it …" Everyone in the courtyard nodded.
Tong Zhengye, Feng Hou, many officials from the Ministry of Works, and some craftsmen were in the courtyard. They were all staring at a wooden board placed in the middle. On top of it were the models that Ren Baqian demonstrated to everyone, including the blast furnace and hydraulic forging equipment.
"Can these two types of iron be made into steel just like this?" A few of the craftsmen were still hesitant. After forging for their entire lives, it was difficult for them to accept being suddenly told that they should do this.
Even more people's faces lit up. Before this, they had never thought that they could actually do this.
It didn't seem difficult, but if Ren Baqian hadn't mentioned these things, they would never have thought of it.
Especially at this critical juncture, the things that Principal Ren took out were really useful.
"Choose a site according to this for the time being. If there are any problems, get someone to inform me immediately. I'm going into the mountains for a period of time, or you can wait for me to come out," Ren Baqian said to everyone.
"By the way, if we modify this water wheel a little, we can use it to irrigate the fields. Think about it."
Ren Baqian and Tong Zhenye left together. Ren Baqian said, "Sir Tong, I have given you the blueprints, the model, and the things that you need to take note of. The rest is up to you."
Tong Zhenye nodded. He naturally knew the importance of this matter.
"Sir Tong, I still have something to do. Follow me to the Great Elder's residence first!" Ren Baqian said.
The two of them brought along their guards and rushed to the Great Elder's house. Then, they were led by a servant to Shi Qing's study room.
"My lords!" When Ren Baqian and Tong Zhenye entered, they saw Shi Qing, Kouzhehai, Qin Chuan, and the others surrounding a box on the table.
"Sir Ren, does this thing really have the effect that you said?" Qin Chuan asked incredulously.
He found it hard to believe that Shi Qing suddenly called him here and then told him that this thing could be used to contact people thousands of kilometers away.
"You will know after trying it out. I have already sent people to Jiaoda yesterday, and it should be about time." Ren Baqian nodded at everyone. Jiaoda was a small city located 400 kilometers north of Lan City.
"What's this?" Tong Zhenye asked curiously.
"A radio station. Put one in Lan City and one in Ping City respectively. You can use this to contact each other at any time. It's like two people talking to each other without any delay. There's no need for the birds anymore. "Ren Baqian's simple explanation shocked Tong Zhenye.
"Do you see this button? This is the switch. First, turn it on, and then adjust the frequency … "Ren Baqian explained while reading the instruction manual.
"How do I use this written on this paper?" Tong Zhenye immediately asked.
"Yes. After I leave, you can find a student from the academy to tell you what's written on it."
"Hey, hey! Hey! "Ren Baqian called out to the box on the table.
This radio station was equipped with a loudspeaker and a walkie-talkie.
"That's it?" Qin Chuan and the others looked at the box on the table doubtfully.
"The radio station isn't turned on over there. Wait for a while. They will contact us when they arrive, "Ren Baqian explained.
After a long time, a rustling sound came from the radio station. Then, someone asked doubtfully, "Is this how it should be used? Sir Ren seems to have said to use this … "
Hearing the sound coming from the box, everyone was shocked.
"Hey, can you hear me? Where are you now? "Ren Baqian asked again.
"Hey, there's actually a sound." The other party was also surprised. Then, they reacted and asked, "Is it Sir Ren? I'm Xu Le, and I'm now in Jiaoda … "
"It's done!" Ren Baqian looked up and smiled at everyone.
With this thing, the next battle would be easier.
How to pursue, surround, and attack were all discussed through the walkie-talkie. It could be said that all the troops were connected.
"Where are you in Jiaoda?" Qin Chuan asked in a deep voice.
Following that, Qin Chuan and Xu Le asked and answered questions. Everyone heard them clearly and no longer had any doubts.
Shi Qing and Zhe Hai were both excited and looked at Ren Baqian with a rather strange look.
"Why are you looking at me?" Ren Baqian felt uncomfortable being stared at.
"Sir Ren, this thing is called a radio station? I don't know how it's done. Can our children learn these things in the academy? "Shi Qing asked curiously.
"Of course. However, we have to take it one step at a time. They still have a lot to learn to make this thing. "Ren Baqian nodded.
"That's good, that's good." Shi Qing stroked his beard and smiled, looking satisfied. This thing that Ren Baqian took out really showed them how amazing it was.
It was even more important than the solar furnace.
"Sir Ren, are you still accepting students?" Zhe Kouhai immediately asked after hearing this. He had a few nephews at home who were considered smart and quick-witted.
Although he was previously against Ren Baqian, he immediately changed his mind when Ren Baqian took out this thing.
"Maybe next year or the year after. I should be recruiting another batch," Ren Baqian replied. At present, there were already enough people. In at least a year, two outstanding students from the first batch would be selected to lead the new students.
Otherwise, he would be exhausted. This group of naughty children was enough to make his blood pressure rise.
"How many of these things are there?" Zhe Hai asked. This question was also the concern of the others.
"Forty should be enough. However, only a dozen have arrived so far. The rest will take some time to arrive. "Ren Baqian nodded.
"Leave this radio station here. If you want to contact Her Majesty or me in the future, just use it."
"Sir Ren, you have done a great service again this time." Tong Zhengye laughed heartily with a happy look on his face. Although this thing wasn't under his control, everyone could see its importance.
"When you come back from the mountains, I will invite you to House Yunyan for a drink!" Tong Zhengye patted Ren Baqian's shoulder with his big claw.
Fortunately, after reaching the Man Wheel level, Ren Baqian's body had become much stronger. If it was in the past, he would have immediately collapsed.
"Oh, is that so?" A woman's voice was suddenly heard from the radio station, causing Tong Zhengye to shiver.
"Your Majesty? Your Majesty? " Tong Zhengye pointed at the radio station in surprise. He didn't expect to hear Her Majesty's voice. Wasn't Her Majesty in the palace?
"What's wrong with me?" The empress's voice was heard again.
Tong Zhengye immediately became submissive and said, "I didn't expect to hear Your Majesty's voice from here. I am too surprised and overjoyed. I hope Your Majesty won't take offense."
Qin Chuan looked at Tong Zhengye and laughed, "Ignorant old man!"
If the empress hadn't spoken just now, he would have dragged Ren Baqian out to drink with prostitutes, allowing him to escape this calamity.
"That's a public channel. Your Majesty also has a radio station, so you can naturally hear it." Ren Baqian smiled at Tong Zhengye, revealing his white teeth.
…
On the third day, Ren Baqian had already arranged for the students in the academy. Among them, 24 had passed the test and were going on an outing in the mountains with him.
The remaining 25 had to wait for their endless homework …
After coming out of the academy, Ren Baqian looked at the palace. The empress would be leaving tomorrow, and he didn't know how many months she would be gone for. It seemed that during this period of time, the two of them would only be separated for a few days at most. This time, they would be separated for a few months, which made him feel a little uncomfortable.
After the empress left, he would return to Earth and set off for the mountains on his way back.
On the way back to the palace, Xu Wei suddenly felt that the atmosphere was a little off. There seemed to be a murderous intent.
This made him nervous. With a wave of his hand, everyone stopped and began to search for the source of the murderous intent.
At this moment, two black iron chains shot out from the ground and entangled Ren Baqian and the fork-horned cow he was sitting on.
"Spirit Wheel experts from Great Xia!" Xu Wei's facial expression immediately changed. "Protect Sir!"
At the same time, he let out a howl to inform the palace guards nearby.
Ren Baqian's facial expression also changed drastically. The two iron chains emitted a bone-piercing chill. He felt as if he was frozen, and his whole body stiffened.
Then, he saw a man coming down from the sky on a sword. He exerted force with his feet, and the huge sword immediately flipped in the air and landed in his hand. The sword was twice the size of his body, and it slashed toward the people below like a meteor.
Ren Baqian, who bore the brunt of the attack, widened his eyes and looked horrified. Then, he suddenly disappeared from the scene.
At the same time, the chains that entangled him and the fork-horned cow also disappeared, leaving the fork-horned cow in the middle of the scene with an innocent look on its face.
A person 100 meters away suddenly spat out a mouthful of blood and cried out mournfully, "Where's my Immortal-binding Chain?"
Blood flowed from his mouth, his eyes were filled with horror, and his whole body was lifeless. One had to know that this iron chain was a Heaven-grade weapon that was condensed from his divine sense. It was nourished by him every day and was connected to him as one. But now, it was actually gone! Gone! Gone!
In an instant, it disappeared along with the target! He couldn't sense it at all!
