The Marquis of Dingbei ordered someone to put down the things and leave, but the old man kept guarding here. He wasn't there when he first exposed the liar, and after hearing about the spontaneous combustion of white phosphorus, he was very curious, and rushed over to see this thing.

When Jiang Xingchen poured cold water on the jar of white phosphorus, even the old man felt his scalp tingle. Needless to say, this is also a means to prevent spontaneous combustion of white phosphorus. In other words, even if it is stored in a jar without air, it can burn.

"Little Soul Dan, you are too insidious! You don't say anything important, if the Emperor really takes these things away, there will be an accident if you don't get it right!" the old man said.

Jiang Xingchen raised his head, a little helpless, he really didn't mean the Yin Emperor, he really didn't think about it. In his previous life, he had checked white phosphorus on the Internet, but how could he remember it so clearly, now he just suddenly remembered it, otherwise he would have dealt with it when he searched for white phosphorus, and that was his own life. At the moment, he himself is a little afraid.

"Old fellow, don't talk nonsense, according to what you mean, my heart is too bad!" Jiang Xingchen retorted vigorously.

"You think your heart is good, but the bad ones are bubbling up! Zhao Danqing and I don't know how much you have lost...... You must have thought that the Great Emperor would confiscate these white phosphorus and deliberately leave a hand!"

Of course, the old man knew that Jiang Xingchen did not do this intentionally, let alone do anything to disregard the lives of others. When he said this now, he was deliberately angry with Jiang Xingchen.

"Old thing, it's too much! I have a good relationship with the Emperor now...... Besides, even if the emperor took away the white phosphorus, it would not be possible to put it in the palace. Even if something happens, it's an innocent person. You see me......" Jiang Xingchen is really faceless this time, and it can't be when it comes to his own character.

The old man was really anxious when he saw Jiang Xingchen. Immediately laughed: "Okay boy, I don't know what kind of person you are! As for it...... Ancestor is joking with you!"

The corners of Jiang Xingchen's mouth twitched, he had let the old guy fix it several times on the way back from Moon Shadow! This was absolutely unbearable, and he had to make up for it.

Of course, the old man would not give Jiang Xingchen a chance, laughed, turned his head and ran away. Anyway, the little soul is very busy, and he doesn't have time to trouble himself, so now he has to get a little cheaper.

Jiang Xingchen depressedly finished dealing with the white phosphorus and continued to busy his work. The second prince and the sixth princess also wrote to inquire about the design of the amusement park.

Originally, Jiang Xingchen was going to copy the amusement facilities that Xingchen led to the past, but after thinking about it carefully, it didn't work. Everything else is easy to do. It's just that bungee jumping is difficult. The rope he uses here is made of animal tendon thread and demon Jiao's tendon, elasticity, load-bearing, and safety are no problem....... but elsewhere, rubber has to be used.

The elasticity and tearing strength of natural rubber products are very high, and they can be mixed with animal tendon threads and even added metal reinforcement...... But there's one thing, not right now!

"Hey~" Jiang Xingchen sighed, he used to live without rubber. But with the development of the territory. With the progress of production and life, the status of rubber has become more and more prominent!

After writing down the general meaning and sending it to the second prince, Jiang Xingchen ignored the amusement park for the time being. This project is not something that can be accomplished overnight.

After everything was done, Jiang Xingchen continued to study the steam engine. This time. Here's the conundrum.

Jiang Xingchen originally thought that the steam engine was not difficult, and the fuel was heated by water to produce steam. The steam passes into the cylinder block and pushes the piston to move, which then drives the flywheel...... Although it seems to be just a process of converting thermal energy into mechanical energy. But it's not that simple. First of all, the internal pressure of the boiler will be very large, which requires the material of the boiler. Welding with cast iron is definitely not good, how much pressure can be withstood by how much high-strength steel, and how much power is needed to drive the flywheel, this is all true.

And this is much more complicated than when the kiln mouth was designed. Just making a boiler consumes a lot of manpower and material resources.

In addition, the internal pressure of the boiler was too high, and water injection became a problem. Do you want to boil a furnace of water, then stop the fire and refill it......

After thinking about it for two days, Jiang Xingchen didn't find a solution, so he could only continue to study according to the original. The problem of the material is that he has a temperature control pressure array, which is nothing more than a few more tests. However, the problem of water injection is really not good, so we can only design a large-capacity boiler, and stop it after burning a pot. Although the loss is very large, let's take the time to find a way in the future.

Another problem that made Jiang Xingchen feel knotted was fuel. If this problem cannot be solved, it will never be possible to use the steam engine on a large scale, and the impact on the environment will be too great.

On the third day, Dingbei Hou, who had stayed with Wanrou for two days, was about to leave, and Jiang Xingchen of course had to send it in person. On the way back, he turned a corner and went to the Iron Sword Mercenary Regiment, preparing to let the Iron Sword members go on a trip to the Cursed Lands. The hundreds of sacrifices of the empire have to be handed over to the Great Float, so they have to find someone they know.

When he arrived at the Iron Sword Mercenary Group, a member of the team led Jiang Xingchen inside, and before he reached the room, he heard the old man's voice.

"Zhao boy, don't believe it! I really played the little soul lightly, you didn't see his expression at that time, it was so exciting, I haven't seen it in the past few years!"

In the house, Zhao Danqing, the second brother, and the old man chatted while playing cards. Speaking of playing Jiang Xingchen that day, the old man was full of energy and proud.

"Old man, if you don't urge the cheating, you can die...... With your IQ, you are still playing Brother Jiang, isn't this nonsense!" Zhao Danqing didn't believe it at all, and laughed loudly while drawing cards.

"I don't believe it either! In Brother Jiang's words, this is called a crab with a chew and a blind beard...... I'll shout first, call the landlord!" said the second brother with a smile.

"Damn!" the old man was not happy to hear this, put the cards in his hand, and took out a letter casually.

"See, this is the letter from that time...... The boy said that gypsum could clear the fire and remove the heat, so I wrote a letter to Huangshi! The next day I used this fake letter to deceive him, saying that Huangshi sent it back...... Guess what, the little soul is afraid that the plaster will eat the dead, so he has to ask me what's going on, and I said it has nothing to do with him, he wants to read the letter, and the result is ......."

The old man threw the letter at the two of them as he spoke, and said with a smile: "My mood has never been so happy as these days!

Zhao Danqing and the second brother picked up the letter and looked at it, and laughed: "Old guy, you are too bad!"

"Didn't you see the expression of the little soul at that time...... Don't move, I'll rob the landlord!" the old man stretched out his hand and turned over the hole cards.

Zhao Danqing and the second brother didn't care either, and asked again: "Old man, is it really good for you to do this?

"Cut! When did he not use this to scare me, in the end, which time did I not eat ......" The old man said indifferently while sorting out the cards: "Besides, even if this kid doesn't do it, the Buddha jumping over the wall made by the chefs of several major restaurants now tastes quite good, definitely not worse than Mei'er's adult birthday...... I'll just go to the restaurant later!"

"Old man, you cow!" the second brother picked his thumb and said, "This dish is limited every day, can you guarantee that you can buy it?"

"Of course, don't you know, ribs are the main force of transportation now. It is responsible for all the ingredients that come back from the sea. It's so easy to get some ingredients out of the ribs!"

"High!" Zhao Danqing's eyes suddenly lit up, and he picked his thumb: "Old man, I really admire you!"

"What's the use of admiring me, I'll just follow my ancestors in the future, there will be delicious food every day!"

"Old man, it goes without saying, we are originally a gang, I will follow you! You don't need to have delicious food every day, just one Buddha jumping over the wall every day!" Zhao Danqing said with a sycophantic smile.

The corners of the second brother's mouth twitched twice, one Buddha jumped over the wall a day, this is not a delicious Buddha jumping over the wall every day, but three thousand citrine coins, can you show more face?

Different from Zhao Danqing's sycophancy, the second brother laughed gloomily: "Hehe, Lao Zhao, you can think about it! If you offend Brother Jiang, don't say that you will eat Buddha and jump over the wall, and in the end, don't eat Xiang!"

"I'll go! You just eat Xiang, your whole family eats Xiang......." Zhao Danqing slapped the table and became anxious.

Of course, the second brother was not stunned, and threw the cards directly on the table!

Of course, Zhao Danqing was not afraid, he also threw the cards on the table, got up and looked at the second brother.

The old man looked at the two people facing each other, and then at the mess of poker on the table. Finally, my eyes stopped on my own hand... Two kings, three twos, four ones, and a set of airplanes......

"Damn, you two bastards, give me back a good hand......" The old man was anxious!

The second brother and Zhao Danqing laughed at the same time, turned around and ran to the door.

At this time, with a bang, the door was kicked open, and Jiang Xingchen walked in with a blue face.

The room was quiet for a while, and Zhao Danqing, the second brother, and even the old man behind them stopped.

"Hehe, you guys are having a great time!" Jiang Xingchen suddenly laughed, and the unusually rapid change made several people feel furious in their hearts.

"Brother Zhao, what did you just say, in the future, you will have to mix with the old man and eat Buddha and jump over the wall every day?" Jiang Xingchen asked.

"Ahem...... What's wrong with my head, I'm so dizzy! Is it that I have been playing cards for too long, and I forgot what I just said...... No, I have to go and take a break!" Zhao Danqing looked ignorant, rubbed his temples and walked directly past Jiang Xingchen.

"Lao Zhao is tired enough, I'll go see him!" the second brother laughed and ran away.

The last remaining old man, looking at Jiang Xingchen's smile, felt panicked, swallowed and spitted and said, "Boy, I also have something to do, let's go first!"

"Old man, thank you!" Jiang Xingchen said suddenly.

"Uh!" the old man was stunned for a moment and asked, "What do you mean?"

Jiang Xingchen smiled: "If I hadn't heard you hack me, I wouldn't have found inspiration!" (To be continued......)
