Li Zisheng entered the gate of the research branch, saying that the branch was actually just a yard and a few ordinary houses. The only surprising thing was that a large shed was built in the yard.

When he entered the door, he saw Hu Yunduo busying himself in the shed. The target of his work was an iron box with many tubes on it. Because he was too focused, he didn't know even if someone came in.

Mr. Li didn't care, and came to the front of this strange box and looked at it.

However, Hu Yunhong, who was behind him, coughed gently, which made his brother notice them.

"Junior Brother Li, you are here." Although he looked a little haggard, his hair and clothes were messy, his eyes were bloodshot, and even his voice was a little hoarse, which made people know that he was lacking rest at first sight, but he was very excited and did not look listless at all.

Li Zisheng felt warm in his heart. Senior Brother Hu in front of him reminded him of several colleagues from the Equipment Department of the Liberation Army. He stepped forward and bowed, and said emotionally: "Senior Brother Yunduo, you have been reduced."

Hu Yunduo also clasped his fists and said, "Hahaha, Junior Brother Li is so serious, I am so energetic."

Mr. Li sighed and said with emotion: "I brought some elixirs here specially. I have to do some research. Senior brother, your cultivation should not be delayed. You must be more careful in your body, otherwise I will be very guilty."

Hu Yunduo said a little embarrassedly: "This is natural."

Then he clapped his hands and pointed to the iron box and said happily: "Please look at Junior Brother Li, this is the internal combustion engine I told you on the message talisman."

Li Zisheng carefully made a lot of things, feeling that they were a bit similar to the similar things seen in other worlds.

When Hu Yunduo talked about his work, he was dull and said nonsense: "Junior brother, the idea of ​​the internal combustion engine you told me last time was very good. Yuanshi can indeed be stimulated with true qi, but as long as the Yuanshi is ground into powder, it can burn even when it encounters open flames. We created this internal combustion engine according to this idea."

As he said that, he picked up a bag from the table next to him, which contained Yuanshi that had been grinded into powder. Then he poured the powder into an opening with a small door on the side of the box.

Next he pressed a button on the box, and with a "crack" sound, the box started to move. The pillars on it began to rise and fall rhythmically. Their speed was getting faster and faster, and the roar became louder and louder...

"Not good. Everyone retreat quickly!" Hu Yunduo's face changed and he said loudly.

He also had experience and hid behind the courtyard wall "swoosh".

The yard is full of well-trained young cultivators, and they reacted very quickly, and they followed him to get out of the yard.

Li Zisheng landed on the ground with his front foot. He heard a loud noise in the yard, and then several metal parts flew over the wall and landed far away.

Fortunately, this research branch is located in a secluded place outside Yuan'an City. Otherwise, it would have caused casualties.

"Well, it seems that the Yuan stone powder has been added. After the Yuan stone is ground into powder, its temperament becomes extremely violent and it will easily explode." Hu Yunduo scratched his head embarrassedly and said to Mr. Li San.

This is not surprising. The surface area increases in the powder state. The more oxygen it comes in contact, the more it burns, and the physical properties will of course become "extremely violent". In fact, even flour will explode violently when it encounters fire, not to mention the Yuan stone that is originally an energy crystallization.

Li Zisheng was not unhappy. Instead, he patted his shoulder enthusiastically and encouraged him: "Senior Brother Yunduo, is failure the mother of success? It doesn't matter, take your time. Be sure to pay attention to safety."

"Well, save me the loss for my brother. But..." Hu Yunduo nodded and then asked, "Failure is the mother of success, this sentence is well said. But Junior Brother Li, why is it a mother rather than a father?"

Since the internal combustion engine model was damaged, the two went into the house together and began to talk about their recent work arrangements. After talking about the various things, Li Zisheng hesitated for a moment and asked: "Senior Brother Yunduo, the Five Elements Chariot... seems a bit big and unreasonable."

Hu Yunduo nodded and said, "I have also told me that the self-propelled artillery design is good, but it is a bit ahead of the curve. The current one, well, the technology is not enough."

Mr. Li smacked his lips a few times, and finally couldn't help asking: "Senior Brother Yunduo, the radish head I mentioned to you last time was the steam mecha. Do you think it can be done with the current technical conditions?"

Hu Yunduo shook his head and said, "The steam mecha you mentioned is much more complicated than the self-propelled cannon. If you want to make such a large iron man move like a human, the joints on the limbs will be strong, and it is probably only my father's skills to make it. Even if it is made, if the materials can withstand wear, ordinary iron will definitely not work, and the cost will go up."

"Secondly, Junior Brother Li said that he wanted mortals to control mechas. This was almost impossible. According to my calculations, their body bones were too weak, and even an emergency stop could cause their internal organs to break. Well, even if we cultivators were allowed to manipulate them, the violent movements would not be big. If the junior brother said that he wanted to fly, jump, beat and guard, everyone inside could become a ball of meat sauce."

"Again, it's okay to make such a mecha into four-legged and six-legged, but it's too difficult to have both feet. How can such a tall mecha maintain balance? Where should the center of gravity be placed? It would be strange if you don't stumbling when walking. And if you use both feet as support, Jiaguang may fall into the ground when standing on the mud, and it's better to use tracks as a mobile device as a five-element chariot."

"Finally, the steam engine is not good now. Just like the junior brother, you said, the power is too small. Not to mention how to add fuel, the mecha cannot be made too small, otherwise even the steam engine cannot be placed. This is another dilemma. Unless our internal combustion engine can be successfully tested, we can try it."

Mr. Li San thought that what Brother Hu said was very reasonable. No wonder there was no mecha organization in the Liberation Army, but the memory in his mind clearly told him that large mechas are a very confusing weapon.

Not only is it a trick, but it is also very majestic. If it can still be deformed, it would be even more amazing...

"Anyway..." Hu Yunduo is indeed a scientist's style. He talked so naggingly for a long time before finally saying: "It's unlikely that thing is now made. But..."

"But what?" Li Zisheng, who was hit hard once, cheered up again and asked.

"But the mechanical exoskeleton you mentioned is feasible." Hu Yunduo said frankly.

Mr. Li asked anxiously: "Oh, what do you mean?"

Hu Yunduo scratched his head and said, "Actually, the exoskeleton you are talking about is nothing more than armor. It's easy to make it. Then just add a few sets of talisman arrays on it."

"If you think about it this way, this exoskeleton is very confusing. If... if... if all its parts are magic weapons and then combined together, then this power..."

The more he spoke, his eyes became brighter and in the end he couldn't help but stand up and circled around the room.

Li Zisheng said disappointedly: "In this way, it can only be used by cultivators."

"Yes, why do mortals want that thing?" Hu Yunduo stopped and asked strangely, "Junior brother, you are indeed a genius, you can think of others but not. But this idea is wrong."

"Where did this come from?" asked Mr. Li San.

Hu Yunduo said with a heartache: "What do you think of is how to use mortals? Yes, there are more mortals, but there are few Yuan stones in their hands. Even if they really make them, they don't buy them. Isn't this a waste?"

Alas, it’s hard to find a soulmate. It seems that this Senior Brother Hu cannot understand his true intentions.

When Li Zisheng thought of this, he could only sigh secretly, but he immediately cheered up and wanted to follow this conversation and educate Hu Yunduo.

At this moment, someone outside the door reported: "Your Excellency General Secretary, a guest is visiting." (To be continued...)
