The vacuum furnace needs to use the vacuum system in the specific space of the furnace chamber to discharge part of the substances in the furnace chamber, so that the pressure in the furnace is less than a standard atmospheric pressure, so that the vacuum attitude in the furnace chamber can be achieved.

Whether it is the furnace body or the vacuum system, it is not easy to do.

Especially vacuum systems.

Chu Ze had read books on this subject out of curiosity, and he knew a little about their structure, and he could draw them.

But Chu Ze was worried that things couldn't be made.

Also, the action of the vacuum furnace requires power.

In modern times, these powers are electricity.

But now it's Daming.

Hundreds of years from modern times.

These hundreds of years are not only the time gap, but also the difference in science and technology.

Electricity......

Chu Ze didn't dare to think about it for the time being.

However, the steam engine can be used.

Yes, first draw something and make a model.

And then overcome the difficulties.

When the vacuum furnace is successful, he can use dolomite to extract magnesium.

Magnesium has a wide range of uses, both medical and military.

It can even be used in plants.

Chu Ze thought of it, he took out the pen and paper, and began to outline the prototype of the vacuum furnace and vacuum system little by little according to the appearance in his memory.

Until I arrived in Xisui, I had already drawn several drawings.

The carriage stopped, and Chu Ze didn't take his head, so he asked, "Arrived?" ”

There was silence outside for a moment, and then Zhao Si's voice sounded: "My lord, Wan Qishen is at the gate of the city, standing with Lord Qi and them, as if they want to pick you up?" When it came to the last few words, Zhao Si was very unconfident and a little doubtful about life.

Lord Qi will come Zhao Si knows, but Wan Qian is deeply ......

Hiss~

made Zhao Si think of an allusion - the weasel gave the chicken a New Year's greeting, and he was uneasy and kind.

Chu Ze paused, puzzled, "Huh? With a sigh, he quickly got up and lifted the curtain, and sure enough, he saw Wan Qianshen who was smiling like a spring breeze, and Lord Qi who was smirking next to him.

Seeing Chu Ze showing his head, a formulaic smile appeared on Wan Qishen's face.

He arched his hand, and was about to say something, when he saw Chu Ze put down the curtain and retreated.

There is no intention to say hello to Wan Qianshen at all.

"......" Wan Qian stood in place, his forehead jumped a few times, and his eyes looked at the past, eager to shoot through the carriage.

Chu Ze, I don't know how to lift!

Soon Wan Qishen laughed again.

This time, the smile is much more real than before.

"Lord Chu, what's wrong? But did you encounter something on the road that upset the adults? Why don't you come down to meet people when you arrive? This official is nothing, but Lord Qi and they have been waiting all afternoon. Wan Qian calmly put down and walked towards the carriage.

In his opinion, Chu Ze must have been annoyed, so he didn't want to see him.

The more Chu Ze didn't want to see him, the more he had to lean in front of Chu Ze.

Not for anything else, just to poke the mallet in Chu Ze's eyes.

If Chu Ze is not angry, he will also be mad.

But how did he know that Chu Ze retreated completely to clean up the drawings.

As for Wan Qianshen's little tricks, in Chu Ze's eyes, he was no different from a little flea.

It's an eyesore, but it's easy to extinguish.

Chu Ze put away the drawings before they came out.

At this time, Wan Qianshen happened to be stopped by the guards.

"Lord Wan Qi really cares about us, and he cares so much about whether we are happy or unhappy every day." Chu Ze smiled and squeezed, "Sure enough, once it gained power, it was rampant." ”

Wan Qishen's face instantly darkened.

This is a satire on him, Kang Cheng was suppressed from time to time.

But that's in the past.

Wan Qishen put on a face again without smiling, and said, "Lord Chu is an envoy of the kingdom, so I naturally have to pay attention." This time, Lord Chu has been out for so long, he must have gotten something good, right? It's better to take it out and open our eyes. ”

Lord Qi and the others' eyes lit up.

They don't like Wan Qianshen, but they like Wan Qianshen's words very much.

Chu Ze looked at Lord Qi and the others who were looking at him blankly, and after being silent for a moment, he said with a smile: "It's nothing, it's just that I have taken a fancy to a few stones." ”

"Lord Wan Qi, the officials of your country are not good, have you not given money to others, or are you greedy yourself? Even a few stones were grabbed. Chu Ze jumped out of the carriage and walked in front of Wan Qianshen, he waved his hand, and the guards retreated.

Chu Ze looked at Wan Qianshen and laughed mockingly.

Wan Qianshen's face sank a little more.

He looked at Chu Ze fixedly, and said with a smile: "The stone that can be favored by Lord Chu must not be an ordinary stone. Besides, this is the territory of the Ryukyus, and every grass and tree is owned by the Ryukyus, and they are just doing their duty to guard the things of the country, how can they say that. ”

"Hahahaha...... is worthy of being brought out by Lord Wan Qi, and even the words are the same. It's not going to be what you teach word for word, is it? Chu Ze looked at him with a smile.

Wan Qian looked back calmly: "This is the consciousness that this Ryukyuan people should have. ”

"Snort, it's obviously shameless, and it's so high-sounding." Zhao Si on the side couldn't listen to it anymore, and rolled his eyes and muttered in a loud voice.

Wan Qishen swept the knife with a slap in the eye.

Zhao Si closed his mouth very blindly.

seems to be convinced, but in fact, he turned his head to the side and engraved the word "dissatisfied" directly on his head.

Wan Qian grinded his teeth deeply, but he didn't plan to deal with a small guy, which would lose his identity.

But he can be calculated from Chu Ze.

"Lord Chu, your servant is too rude." Wan Qi looked at Chu Ze with deep condemnation.

Chu Ze smiled at Wan Qianshen slightly, and protected his shortcomings with confidence: "To tell the truth, how did it become rude?" ”

"You!"

"Come on, it's getting late, Lord Wan Qi should go back." In the middle of the night, Chu Ze was too lazy to talk nonsense with Wan Qishen here.

No matter what Wan Qianshen's expression was, he bypassed Wan Qianshen and walked towards Lord Qi and the others.

Lord Qi listened to the whole process, but he was confused.

Seeing Chu Ze coming over, after seeing the ceremony, he hurriedly asked what was going on.

Chu Ze turned his head, glanced at Wan Qishen meaningfully, and said loudly: "It's nothing, it's just that I went out to find some stones, and someone snatched him as a treasure." ”

Who is this "someone" referring to, Chu Ze's eyes just now have made it clear.

Lord Qi was filled with righteous indignation.

"These people are too shameless, they even grab stones!"

"That's it, my lord, let's go back to China immediately to play the emperor, and directly press the army to see if they dare to rob your things!"

Chu Ze: "......" These civil officials, who are usually literary and only glaring angrily, have a more irritable temper than him.

"Do you still use our army to suppress the realm? Didn't His Royal Highness the Crown Prince of their previous dynasty already bring people to Chen Jiang? Lord Wan Qi has to fight hard, don't get up tomorrow, you will become a prisoner. Chu Ze sneered again, and swaggered into the city with Lord Qi and the others.

Wan Qishen's face darkened. (End of chapter)
