The son of the An family and the head of the An family were silent, and Jiang Xingchen confessed to the occupation of the Nangong family on Aliu Island this time. If this matter is put on itself, will Chongming Island dare to send troops?

The answer is certain, we must have troops, otherwise where is the prestige? But what about sending troops, sixteen killer whales dominate the sea area, and if they go, they will be sent to death, just for the sake of a reputation, don't be so frightened that they don't dare to show their heads.

What they didn't know was that this time Mandan Island was not cowardly, but was fooled by Nangong Shizi. The head of the Nangong family and the elders all thought that it was a good thing to be able to contact Jiang Xingchen, and if they got along, they might be able to get a steam engine. In this mentality, they did not come out, but admitted the bet. But even so, there are still many people in the high-level of Mandan Island who are not popular, and they ask Nangong Shizi how to contact him and how to prove it.

Nangong Shizi is also very nervous these days, if Mr. Huang's judgment is wrong, and Jiang Xingchen does not agree to sell cement technology, then it will be exposed.

Fortunately, on the sixth day before the departure of the Wang family's fleet, the sea eagle that Wang Zhicheng took with him flew back and brought Jiang Xingchen's letter. Half of the cement formula, as well as the selling price, 100,000 yuan. At this point, his hanging heart was put down.

Then Nangong Shizi immediately ordered to send some people to guard Aliu Island, so as not to let people steal and dig ores. He personally transported 100,000 yuan of stone to Linhai City and exchanged the other half of the formula back.

Jiang Xingchen's letter and half of the cement formula can be regarded as blocking the questioning voices in Mandan Island.

After six days and six nights of full sailing, the Wang family's fleet traveled nearly 7,000 miles, and there were still two days to sail from Linhai City. It's much faster than when the young master of the Mu family went.

Halfway through, the young master of the Mu family left the team. They went to Sharman Island.

And at this time, Jiang Xingchen was also relieved. If a qiē shun lì, the sorghum will be shipped back by June 30th. That before the end of July. You can brew a fragrant liquor.

Although summer is not the season to make liquor, he has a sense of temperature control pressure array, of course, there is no need to worry about temperature and humidity regulation.

As for the cement formula sold to Nangong Shizi, he didn't even hesitate, this is giving money for nothing, why not. Otherwise, let him buy it from the son of the An family. In fact, after receiving Wang Zhicheng's previous letter, and seeing the negotiation with Nangong Shizi, he knew that the other party must have bought papermaking from Chongming Island, so he was not afraid of Wang Zhicheng's threat with paper.

Since he can buy papermaking from Chongming Island. Then it is possible to buy a cement formula, and Jiang Xingchen must of course start first.

In addition, he also discovered that there must be other secrets on Puli Island, otherwise Nangong Shizi would not be so careful. But he didn't care about any secrets, after all, it had nothing to do with him.

It's already early June, and the construction of the light rail road has been going on for almost a month. Compared to the road in the Cursed Lands, the progress of the various forces is much slower, and even if the production scale of the light rail has been expanded on the side of Minggang City, it is far from meeting the demand. It can only slow down the pace of construction. There is no way to waste labor, and there is an increase in consumption.

"Spend more, spend more! These laborers will be the main force in laying railways in the future, and they can't quit!" Jiang Xingchen sighed. Get ready to get up and get the brewmaster ready.

Before he could go out, the old man walked in, and the day before yesterday he came back riding ribs.

"Boy! I haven't forgotten this time, so hurry up and bring it!" the old man stretched out his hand as soon as he entered the door.

Jiang Xingchen asked jokingly, "Reward." What reward?"

When the old man heard this, he was anxious: "Boy, don't admit it." What did you say when you dragged me out of retreat?"

"At that time, I meant to give you a reward!" Jiang Xingchen nodded in acknowledgement.

"Then you still don't give it to me, do you know how tiring it is to run this trip overseas, I went to Aliu Island by myself, and it took tens of thousands of people to snatch the island back......" The old man foamed at the mouth and danced with his hands.

"One person fights tens of thousands of people!" Jiang Xingchen is full of black lines, this old thing is not even reliable!

"I wanted to reward you, but my new tea is half missing, what's going on?" Jiang Xingchen asked.

The old man blinked and said loudly: "How do I know what's going on with half of your tea missing, does it have anything to do with the reward?"

"You still don't admit it, you said that you leaked your mouth before leaving!" Jiang Xingchen sneered.

The old man shook his head: "I don't know what you mean!

"Old thing, you have a hard mouth! And said that you didn't steal, after you left, I went to your yard to see, and the tea leaves that had been brewed were thrown in the corner, and you still didn't admit it!"

"No way, I've thrown everything that has been brewed into the water...... Uh!" The old man's face changed halfway through his words, and the corners of his mouth twitched, this little soul was too insidious, and he was accidentally fooled again.

"Hmph!" Jiang Xingchen sneered: "Hard mouth, you continue to have a hard mouth! Steal my tea, and you still want a reward, you are beautiful!"

The old man drooped his face and said in a low voice: "Then you can tell me what the reward is, let me have a good time!"

Jiang Xingchen continued to sneer: "Old thing, you are really getting more and more thieves! Listen to the reward, if it is good, return the tea, if it is not good, fortunately, don't want it, keep the tea!

The old man's forehead jumped, and he said loudly in anger: "Do you have a steam engine in your brain, spinning so fast! Let me die at once!"

Jiang Xingchen smiled and said secretly: "I don't have a steam engine in my head, but I have something that is countless times more powerful than a steam engine!"

"Forget it, forget it, I don't want the reward, anyway, the things you said are basically unreliable, what kind of drawing circles and squares, I haven't seen it work after practicing for so long. It's better to enjoy the spring tea!" The old man said and turned around and walked out, but when he reached the door, he stopped, turned his head and smiled: "Boy, don't be complacent, be careful with the rest of your tea!"

"Old thing, you dare!" Jiang Xingchen's face also changed, it was no problem for his IQ to crush the old man, but if this old thing did it, there would be no way, and it would be useless to hide it secretly.

Seeing Jiang Xingchen's angry appearance, the old man was finally refreshed, turned his head and ran away without a trace.

"This old thing, it's really untidy!" Jiang Xingchen exhaled and thought about it, I can always bring the tea leaves with me, how can he steal this...... No, how can I put it on this hot day

He was pondering this, when he saw Xian Ning running in from outside the courtyard with a roll of white paper in his hand.

"Why did you come here while running?" Jiang Xingchen couldn't help but be stunned, Xian Ning has always been steady, and he has never seen her like this.

"Xingchen, I've thought of it, I've thought of it!" Xian Ning said breathlessly as soon as he entered the room, with excitement on his face that could not be concealed.

"What did you think of?" Jiang Xingchen asked, and immediately reacted, and said in surprise: "You mean, the braking system of the steam locomotive!"

"Hmm!" Xian Ning nodded vigorously.

"Tell me about it!" Jiang Xingchen immediately pulled out the chair and asked Xian Ning to sit down. Then he sat down next to Xian Ning by himself.

Xian Ning opened the scroll of paper in her hand, which was full of graphics and numerals.

"You see, we can add another cylinder and use steam to brake, and that's the whole structure, when you need to slow down......"

Jiang Xingchen listened to Xianning's explanation, nodded again and again, the design of this braking system is very reasonable, and he can't find anything in doubt by looking at the drawings.

After Xian Ning finished explaining, Jiang Xingchen raised his thumb: "Heavy dà breakthrough!Xian Ning, your efforts for so long have not been in vain, this braking system, there should be no problem!"

Xian Ning laughed happily and said, "I can't be so sure, this is just a design idea, and in the end, we have to see the actual result!"

Jiang Xingchen said: "In mid-August, the steel plant on the side of Hongyuan City will be completed, and it will be able to produce parts and heavy rails immediately, so let's lay a section for real use first!"

"Okay!" Xian Ning nodded and said, "If it is a qiē shun lì, maybe the train will be officially put into operation before winter!"

"Hahaha...... If it can be put into operation before this winter, it will be completed within three years, and the old man will lose!" Jiang Xingchen laughed.

Xian Ning shook his head, sometimes Jiang Xingchen is really like a child, the opening of the train has a lot of meaning, but what he pondered was to make a bet with the old man.

"By the way, Xianning, you've been busy for a long time, let's take a break in the past two months!" Jiang Xingchen said.

"We can't rest now, we designed a locomotive to drive four pairs of wheels, and a steam engine to drive five cylinders. This requires higher temperatures and greater internal pressure for the boiler, so new alloys must be researched to make the boiler. ”

Jiang Xingchen frowned, the train that appeared first in the previous life should not be so complicated. Now the steam locomotive they are working on seems to be a little ahead of its time!

"Xingchen, is there any problem?" Seeing Jiang Xingchen frowning, Xian Ning asked.

"I'm just worried about your physical condition!" Jiang Xingchen said.

"It's okay, we're already familiar with studying alloys, so we shouldn't be so tired...... By the way, there's one more thing! I'm afraid I won't have much time, physics and chemistry are still up to you!" Xian Ning said.

"Okay! I'll try to find time! But these two things are really not easy to get!" Jiang Xingchen said with a smile.

"Is there anything else that is difficult for you?" Xian Ning smiled and teased, and then stood up: "Okay, I'll go back first!"

"Xianning!" Jiang Xingchen stopped her and said, "Don't go back today!"

"Huh?" Xian Ning was stunned at the time, and then her face seemed to be painted with rouge, and she said coquettishly: "What are you talking about!"

Jiang Xingchen saw Xian Ning's reaction, and immediately understood that he had made a mistake, and hurriedly said: "Don't get me wrong, I mean that the steam locomotive broke through today, let's celebrate, let you stay here to eat, and I'll cook it myself...... That's not what it means!"

"You still say!" (To be continued......)
