In the next two days, Ren 8,000 went to school during the day, and in the afternoon, he soaked in the Ministry of Engineering, and studied the next two important things with Tong Zhenye, the blast furnace and the steel filling method.

The blast furnace used is close to the blast furnace used in the Song Dynasty, which is already very close to the modern blast furnace, and uses charcoal instead of coal, which is more suitable for the current Bactria .

However, the following is a hydraulic air drain, which drives the wooden wheel through the water flow, so that the water hits the wooden wheel and rotates, and then through the mechanical transmission devices such as the wheel shaft and the pull rod, the wind row is continuously opened and closed, the wind is greater, the continuity is better, and the flame is more intense.

Pig and wrought iron can be easily obtained in this method, and can be produced continuously, with the molten iron flowing directly from the side without opening the furnace, and then re-adding the iron ore above.

This alone saves a lot of manpower and material resources.

The next step is to use the steel filling method, in which pig iron and wrought iron are hammered together to make carbon penetrate each other to obtain steel, which can increase the speed of converting iron into steel several times. And there is no need for those craftsmen to build it, this process can be done with a hydraulic forging machine, and what the craftsman needs to do is only the last part.

With this process, Da Yao's iron-making and steel-making speed can be increased by at least ten times.

Then it's time to take it slowly. After all, many things are very good, but Da Yao's production level can't make them.

"See, the water flows down here, washes the wooden wheel, and the wooden wheel drives the lever, and then the hammer will automatically hammer down like this......" Ren Baqian is using a small model to explain to everyone, the model was made overnight after staring at the craftsmen for the past two days.

I saw a small wooden wheel placed on top of a wooden trough, and when water poured on the wooden trough, the wooden wheel would rotate with the current, completing the whole process that Ren Baqian said.

"See......" A person in the courtyard nodded.

In the courtyard, there are copper shocks, wind throats, and many officials of the Ministry of Industry and some craftsmen, all staring at a wooden board placed in the middle, and above it are several models that Ren Baqian demonstrated to everyone, including blast furnaces and hydraulic forging equipment.

"But two kinds of iron can be made into steel like this?" Several craftsmen still had some hesitation on their faces, and they were suddenly told that they should do this, which made them a little unacceptable.

More people have a light on their faces, which they never thought they would be able to do before.

It doesn't seem to be difficult, but if Ren Baqian doesn't say these things, they may never think of it in their lifetime.

Especially at this critical time, these things that Governor Ren took out were so useful.

"You will first choose a site to build according to this, and if there is any problem, let people inform me immediately, I will go into the mountain for a while, or wait for me to come out of the mountain. "Ren 8000 to everyone.

"By the way, this waterwheel can be used to irrigate fertile fields, you can think about it. ”

Ren Baqian and Tong Zhenye left together, Ren Baqian said: "Master Tong, the drawings are also given to you, the model is also available, and the issues that need to be paid attention to have been talked about have also been said, and it is up to you next." ”

Tong Zhenye nodded, he naturally knew the importance of the matter.

"Master Tong, there are still some things, go to the Great Deacon's Mansion with me first!" Ren Baqian said.

The two rushed to the old deacon's house with the guards, and then went to Shi Qing's study under the leadership of Jia Ding.

"Ladies and gentlemen!" Ren Baqian and Tong Zhenye entered the door and saw Shi Qing, Kou Zhehai, Qin Chuan and others surrounding a box on the table.

"Lord Ren, does this thing really have the kind of effect you said?" Qin Chuan said in disbelief.

Suddenly, Shi Qing shouted here, and then was told that this thing could be connected thousands of miles away, which made him a little incredulous.

"Just try it, I already let people set off for Jiaozi yesterday, and the time is almost up. Ren Baqian nodded at everyone. Jiaozi is a small city located 400 miles north of Lancheng.

"What is this?" said Tong Zhenye curiously.

"Radio stations, one in Lancheng and one in Pingcheng, can be used to communicate with each other at any time, as if two people are talking to each other, without delay, in a timely manner. There is no need to move birds. Ren Baqian said it briefly, which startled Tong Zhenye.

"See this button? This is a switch, turn it on first, and then adjust the frequency......" Ren Baqian told everyone while reading the manual.

"How do you use this on this paper?" asked Tong Zhenye immediately.

"Yes, after I leave, you can find the students of the academy and tell you what is written on it. ”

"Hey, hey, hey!" Ren Baqian fed the box on the table.

This radio station itself comes with a megaphone and intercom.

"Is that okay?" Qin Chuan and the others looked at the box on the table with puzzled expressions.

"I didn't turn on the radio on that side, just wait a minute. They'll be in touch when they get there. Ren Baqian explained.

After a long time, the "Shasha......" radio first heard a rustling sound, and then a person wondered: "Is this how you use it?" Lord Ren seems to say that it is according to this ......."

Hearing the sound coming from the box, several people were startled.

"Hey, can you hear me, where are you now?" asked Ren Baqian again.

"Hey, there's a voice. The other side was also surprised, and then reacted: "Is it Lord Ren?" his subordinate Xu Le is now ...... in Jiaozi."

"It's done!" Ren Baqian looked up and smiled at everyone.

With this thing, the next battle will be easy to fight.

Thinking about how to pursue, how to encircle, how to raid, how to attack, all of them are discussed at any time with walkie-talkies, and it can be said that all the armies are connected as one.

"Where are you in Jiao Zi?" Qin Chuan asked in a deep voice.

Next, Qin Chuan and Xu Le asked and answered, and everyone heard it clearly, and there was no doubt about it.

Shi Qing and Kou Zhehai were both excited, and at the same time looked at Ren Baqian with a rather strange gaze.

"What do you want me to do?" Ren Baqian was awkwardly surprised by their gaze.

"Lord Ren, this thing is called a radio station? I don't know how it was done. Can children learn these things in schools?" Shi Qing asked curiously.

"Of course. But the food has to be eaten in one bite, and the road has to be walked step by step, and if they want to make this kind of thing, they still have to learn. Ren Baqian nodded.

"That's fine, that's fine. Shi Qing stroked his beard and smiled, looking satisfied. The thing that Ren Baqian took out really made them see how powerful.

Compared to the solar stove, it is more important to everyone.

"Does Lord Ren still accept students?" Zhi Kouhai immediately asked when he heard this, thinking in his heart that there were still a few children and nephews in the family, and they could be regarded as smart and clever.

Although he was very opposed to Ren Baqian before, Ren Baqian came up with such a thing and made him change his mind immediately.

"Next year or the year after, there should be another batch of recruits. "Ren 8000. At present, there are enough people, at least for a year, and two of the first batch of students will be selected to bring in new students.

Otherwise, he will die of exhaustion. Just this group of bear kids made his blood pressure rise.

"How many of these things are there?" Kou Zhehai asked, this question was also of concern to others.

"Forty, that should be enough. However, only a dozen have arrived so far, and it will take some time for the others to arrive. Ren Baqian nodded.

"This radio station will stay here, and if you want to contact Your Majesty or contact me in the future, you can just use this. ”

"Lord Ren, this time you have done a great job again. Tong Zhenye laughed, with a happy face. Although this thing is not in his hands, everyone can see the importance of this thing.

"When you come back from the mountains, the old man invites you to go to Yunyan Tower for a drink!" Tong Zhenye's big paw slapped Ren Baqian twice on the shoulder.

Fortunately, after reaching the human wheel, Ren Baqian's body was a lot stronger, and if he had changed before, he would have fallen down directly.

"Oh, is it?" A woman's voice suddenly came from the radio, causing Tong Zhenye to snort directly.

"Your Majesty, Your Majesty?" Tong Zhenye pointed to the radio station with a surprised expression, he didn't expect to hear His Majesty's voice in it, isn't Your Majesty in the palace?

"What am I doing?" said the empress's voice again.

Tong Zhenye immediately lowered his eyebrows and pleasing his eyes: "The old minister didn't expect to hear His Majesty's voice here, he was too surprised, too happy, and I hope Your Majesty won't be surprised." ”

Qin Chuan looked at Tong Zhenye's appearance and laughed: "Old horseman!"

If the empress hadn't spoken immediately, he would have dragged Ren Baqian to drink flower wine, so that he could escape.

"That channel just now is a public channel, and His Majesty also has a radio station, so naturally he can hear it. Ren Baqian rushed to Tong Zhenye Yile, a mouthful of white teeth.

......

On the third day, Ren Baqian had already arranged the students in the school, and 24 of them passed the grades, and they went on an outing in the mountains with them.

The remaining twenty-five people are waiting for the soldiers' endless homework......

Coming out of the academy, Ren Baqian looked at the palace, and the empress was going to leave tomorrow, and she didn't know how many months it would take. It seems that during this period of time, the two have been separated for a few days at most, and this time it will take a few months, which makes him a little uncomfortable.

After the empress left, she returned to the earth, and when she came back, she set off into the mountains.

On the way back to the palace, Xu Wei suddenly felt that something was wrong with the atmosphere, and it seemed that there was murderous intent.

This made his whole heart lift, and with a wave of his hand, everyone stopped, looking for the source of the killing intent.

At this moment, two black iron chains burst out from the ground, directly entwining Ren Baqian and the horned ox sitting down.

"Great Xia's Divine Wheel!" Xu Wei's face suddenly changed. "Protect your lordship!"

At the same time, a howl was heard, informing the guards in the palace not far away.

Ren Baqian's face also changed greatly, and there was a piercing chill from the two iron chains, and he seemed to be half frozen in ice, and his whole body stiffened.

Then I saw a person stepping on a sword in the air, and I saw the force under his feet, and the giant sword suddenly rolled in the air and fell into his hand, which was twice as big as his whole person, and slashed down like a meteor towards everyone below.

Ren Baqian, who bore the brunt of the attack, had round eyes and a face full of horror, and then suddenly disappeared without a trace in the field.

At the same time, the chains that entangled him and the horned cow disappeared, leaving only the horned cow in the middle of the field with an innocent face.

A hundred meters away, a person suddenly spurted out a mouthful of blood, and shouted bitterly: "Where is the old man's bundle of immortals?"

I saw blood flowing from his mouth, his eyes were full of horror, and his whole person was stunned. You must know that this iron rope is a divine weapon condensed by his divine thoughts, which is nourished by him every day and connected with him. But now it's gone!

In an instant, it was gone with the target!

And his soul was as if someone had slashed him.
