"So, the essence of war is to compete with national strength. Ten thousand combat puppets sounds frightening, but in fact, it is better to use these materials to build some weapons and send them to soldiers, so that at least tens of thousands of troops can be raised. After all, the cheapest thing during the war is human life." Li Huailin said with a smile.

"Don't insult my invention. I admit that the cost of fighting puppets is slightly higher, but it doesn't take 10,000 yuan to exaggerate. 1,000 attack troops can tear open the opponent's formation at the front of the wrong one. I think the cost of 1,000 is still supported by the state funds now, and... and..." Klaus was a little excited as he said, "You see this!"

While speaking, Klaus took out a drawing from the table next to him: "This is a new work I just developed. I call him the Super Magic Crystal Cannon!"

"This super vulgar name..." Li Huailin held his forehead.

"Compared with the magic crystal cannons used in wars now, my magic crystal cannon has brought the utilization of magic crystals to the extreme, and each cannon is twice as powerful as theirs." Klaus said proudly.

"Have you tried it?" Li Huailin asked.

"Uh... this is still in the research and development stage...my materials..." Klaus said timidly.

"Junior high school physics tells us that forces are mutual. The greater the power of your gun, the greater the recoil you receive. To seek the maximum power unilaterally, you have to think about whether your gun barrel can withstand such explosive power." Li Huailin sighed and said.

"I know this too, so I use a mixed steel bar of black iron and cloud iron to make the cannon body..."

"So I said, cost, cost, how many original cannons can be made by the two materials you mentioned, have you considered?" Li Huailin interrupted before Klaus finished speaking.

As a result, Klaus stopped talking again.

"Okay OK, Huailin..." Gilbert next to him pressed his hands and said that the two of them should not be too excited.

"I said, Mr. Engineer, you are quite powerful about inventions, but real war is not a theoretical matter, it is really going to kill people." Li Huailin said. "But, as long as your invention is slightly changed, I believe it can still be used in actual combat."

"Oh?" Klaus suddenly became excited and grabbed Li Huailin, "Really? How to use it?"

"This is also your invention, this black core?" Li Huailin picked up a black core placed on the table and said. This black core was obviously unused. He was supposed to be put into the unfinished puppet, but it has not been put in yet.

"Of course. I have only recently discovered that using this device can collect black power, store it, and then put it in the combat puppet to drive the puppet to operate. Compared with ordinary magic crystal puppets, my dark puppet lasts longer and can be replenished with black power. It is not a disposable thing like magic crystals." Klaus was very proud of this.

"What would happen if this thing was used on people?" Li Huailin asked.

"Huh? Use it on people? I really haven't considered it..." Klaus thought about it and said. "But in an instant, the human body may not be able to stand it. What will happen? I don't know if I haven't done an experiment."

"The human body cannot stand it? Then the dragon human body..." Li Huailin said.

"Dragon man?" Klaus's eyes lit up, "Yes, if it were a dragon man, he would definitely be able to bear such power, yes. This can instantly allow a dragon man to gain very powerful power, which is feasible!"

"So that's it..." Li Huailin nodded. No wonder Bolun's half-dragon man had this prop on it. It turned out that it was really useful in the dragon man. It seemed that the darkness was doing experiments. I guess they tried it with ordinary people, but the result was not enough, so they targeted the stronger dragon man.

"You are so smart!" Klaus's eyes lit up suddenly and he said to Li Huailin, "Let's think about it quickly. Is this thing useful?"

"It's still a bit troublesome. If you want to use it now, you have to find a group of dragon people to join your army. This dragon person... seems not very easy to find." Li Huailin said.

"As well...so..." Klaus was a little discouraged again.

"But..." Li Huailin made another big turn.

"But what?" Klaus's curiosity was attracted again.

"Aren't you a great engineer? Can't you design it slightly and adjust the output of this black core to a lower level. Don't let it pour out too much power at once. Depending on the different endurances of each race, can you design a version suitable for humans, a version suitable for elves, and a version suitable for orcs?" Li Huailin said.

"Hmm?! Ah! I understand! Yes! This is right!" Klaus shouted, "This... this idea, I... I want to remember it immediately, no, I want to start working immediately!"

While shouting, Klaus started working on the pen and paper on the table to modify the drawings. Because he was too excited, the things on the table were turned around and thrown around, but Klaus had no intention of caring about it at all.

"If we can design a version for human use, how much combat power can he increase?" Gilbert, who was here, also had a lit up his eyes and immediately asked Klaus.

"Well... this... I haven't done an experiment, but I think it should be fine if I double my strength, theoretically." Klaus didn't even raise his head, and replied while drawing a picture.

"Are you interested?" Li Huailin asked Gilbert.

"Of course, haven't you heard him say that doubles the strength of human beings. Isn't this a way to immediately improve their strength?" Gilbert said, "And what he just said was an ordinary person. According to my current body, he should be able to bear more dark powers. I believe it will be useful to me."

"Oh, I just want it?" Li Huailin asked.

"Of course." Giptert nodded.

"Oh." Li Huailin nodded to show his understanding, then walked to Klaus who was working and took away the pen that the other party was using.

"You! What are you doing?" Klaus shouted in anger when his work was interrupted.

"Wait for the painting first, let me ask you first, who came up with the idea just now?" Li Huailin asked.

"Hmm? It's you." Klaus said.

"So this idea is mine. Why are you a great engineer? It's not good to steal my creativity." Li Huailin said.

"Nonsense, this black core itself is my invention, you just improved it." Klaus said immediately.

"Your super magic crystal cannon was also modified based on the original magic crystal cannon. How can you say it was your own invention?" Li Huailin asked back.

"This...this..." Klaus was immediately stopped, and thought about it and said, "You are not an engineer."

"Oh, does this matter?" Li Huailin asked, "If I'm not an engineer, can you copy my creativity?"

"Okay, just treat you selling that idea to me. What do you want? Let me talk first, I don't have gold coins here." Klaus said with an unhappy look on his face.

"We are not destined to cooperate with you," Li Huailin said with a smile, feeling like he was planning.

"Cooperation? Well, after all, you also want my engineering invention. OK, what do you want, let me tell you." Klaus was not very surprised by this. Anyway, he had no money, and the only thing he could do was to have the engineering invention. The other party was very proud of him when he fell in love with him.

"Please join our thieves." Gilbert, who was next to him, suddenly inserted in and said.

"Ha?" Li Huailin was shocked. He thought that Gilbert just wanted his invention, but he thought that he wanted to just pack and take the person away. It was indeed the most enjoyable, but he might not be willing to do so.

"Robbers?" Sure enough, Klaus was stunned for a moment, and then smiled, "Why am I going to join the Robber Group? I am an engineer."

"Please be sure to join us." Gilbert was not very good at speaking, so he could only say earnestly.

"I won't join any thieves. I will continue to study and don't have that time to do it." Klaus refused.

"I think you can consider it." Li Huailin here saw that Jibert was able to speak, so he also said this according to his meaning. Anyway, if it really didn't work, he pulled it up and slapped it again and said.

"Think about it? I am an engineer, I only like to do research. You asked me to join a thief group? It's not that I have any prejudice against the thief group, but that will disturb my research. No, no," Klaus said.

"You first see if the research you did is useful. You just said that you have been here for a hundred years, but what you made... I just said, all are out of reality, and the practical value is about zero. The only useful thing is what I have come up with for you. Do you think it is?" Li Huailin said.

Klaus nodded, "What do you say?"

"It's useless to build a car behind closed doors. If you study it for another hundred years, it's just this kind of water product. However, if you join the thief group, you can know the needs as soon as possible and how to improve it. This will not be more helpful to your research." Li Huailin said.

"Huh? It seems that there is something to make sense." Klaus nodded, "But why should I join the thief group? I just need to go to the ground regularly to check it out?"

"You otaku can ask what engineering items others need?" Li Huailin said, "You have said you haven't seen humans for twenty or thirty years. Do you know how to communicate with people?"

"Hmm..." Klaus felt a little hesitant again.

"If you join, I will take care of the members not to disturb your work, and we will provide it if you need any materials." Gilbert also said.

"I..." Klaus was about to say something when suddenly a shout from the door came from the door.
