Such high-quality anesthetics can only be purchased in the human area. Chen Tu secretly sighed that the level of human development will not be able to catch up for a while.

"Okay, let's produce bullets first, I'll figure out how to deal with narcotics." Chen Tu said.

The design of the narcotic bomb was found by Chen Tu from the crystal network, this kind of old-fashioned means of production, people disdain to encrypt at the root, and only need a simple associative search to find.

The tranquilizer bullet itself is particularly thin and requires a special muzzle fire. Behind it is a bullet-like cartridge case, and in front is a very thin hollow metal needle that is attached to the bullet at right angles, which prevents the bullet from recoiling too much to get on the animal.

After hitting the prey, due to inertia, the booster device will squeeze the anesthetic, so as to achieve the purpose of injection. This small bullet looks simple, if it is really produced, Yuemo is estimated to be the only one in this house.

After lunch, Chen Tu had a short sip in his bedroom, and when he woke up, he went to Yin Ying's room.

"We need to buy a batch of anesthetics." Chen Tu walked up to Yin Ying and said.

Otowarbler is dealing with the financial problems of Shinichi, which now has human employees, so Otoying has to deal with various reports and contracts with various companies every day, which is no easier than Demock's work.

"Uh, ahhh Yin Ying, who didn't hear what Chen Tu said, raised her head and looked at Chen Tu on the table.

"We need to buy a good quality batch of anesthetics."

"Anesthetics? Okay, I'll place an order on Crystal Network later, how much do we need? Yin Ying said.

Chen Tu calculated in his mind, according to the calculation of the medicinal power, one ammunition needs to be loaded with three drops of anesthetic. A hundred rounds of ammunition for each rat requires 100,000 rounds of ammunition. That is, 300,000 drops, according to 20 drops per gram, it takes 15 kilograms.

"Buy twenty kilograms, that's probably enough."

"Okay." Yin Ying quickly searched for drug companies on the Internet, and the average price of a kilogram was 10,000 earth coins, and Yin Ying transferred a good reputation and placed an order.

"Alright." Online shopping is fast, and this is exactly where the human zone comes in. Looking at the operation of the sound warbler, Chen Tu nodded with satisfaction, the sound warbler has grown a lot during this period of time.

"By the way, how much balance does our company have now?" Chen Tu only cared about the war, but he didn't care about the economy, and then he thought of this, so he asked.

Hearing this, the sound warbler blew its beak and bulged. He pursed his lips and said, "Two months ago, Uncle Democrus sent me a batch of precious metals. After the mortgage, our company still owes 730 million Earth Coins. ”

"It's fine." Hearing this number, Chen Tu felt that it was okay.

"It's okay, now if we don't buy any big projects, we can gradually pay off the bank loan." Yin Ying said.

Now the economy of the cuckoo area is quite healthy, the economic structure is the output of source crystals, and meat processing accounts for half of the country, plus clothing, and some luxury metals account for a fraction.

"This shows that our development is okay, and we are one step closer to my goal." Chen Tu said proudly.

Yin Ying still has a lot of work to do, and Chen Tu can't keep talking. An hour later, Chen Tu left Yin Ying's room. Although Chen Tu had a sense of loss, he knew that Yin Ying was not much more idle than himself, and he still had a lot of work to do.

Chen Tu got in the car and returned to Wucheng from Cuckoo City, where he worked. I haven't looked at it for a day, and there are already a lot of emails in Chen Tu's mailbox.

The first letter was sent from the city of Labria, signed by Randy. It reads: In the past two weeks, the main force of Yuemo has gradually become closer to the Tami Basin, and the materials that Tami has sent to the Londo District have gradually increased. Did the troops of the cuckoo move?

The reason why Chen Tu did not intercept Yuemo's logistics troops was to retaliate for the incident in which the other administrative regions retreated without telling the other. The suppression of other administrative regions is also conducive to the expansion of living space in the Cuckoo District.

As an administrative region loyal to Tianyu, Chen Tu naturally can't do it himself, so the army of the Yuemo family is a good knife, and if this knife doesn't cut other administrative regions to pieces, Chen Tu won't do it.

"Keep an eye on them and leave them alone." Chen Tu replied.

Then, Chen Tu pulled out a blank page. He needs to formulate a strategy for the future of the cuckoo area, in this turbulent moment, without a good plan, he will fall into the pit of others at any time.

"It's time for the Air Force to form it." Chen Tu pressed his cheeks and thought about it.

In human cognition, multi-class cooperation is the king, and a single class of troops will only make the army extremely unbalanced. Chen Tu set his sights on the human area, and in the Hundred Years War of Mankind, there was no land combat of absolute significance.

Airborne troops are blooming everywhere, and these unexpected units, combined with the extremely strong individual combat capability, can often maximize the destructive power.

Of course, all this requires huge funds to burn, and Chen Tu's current economy is at best the size of a small human town, and it is simply impossible to build a modern army.

Chen Tu then turned his gaze to the history books of mankind to see if he could find a weapon system of good quality and low price. After some research, Chen Tu discovered. In low-altitude combat, helicopters were simply the hegemon of the time. With the advantage of the sky, it can strike accurately, especially in urban combat, if a tank meets a helicopter, it can be completely one-to-ten.

Of course, this kind of helicopter refers to a human helicopter, and the mouse helicopter can only be installed with a machine gun for the time being. During the driving process, the driver alone cannot complete all the operations including the attack.

Due to its age, the internal core structure of the helicopter can no longer be searched on the crystal network. Moreover, human beings no longer use such a low-level power system, and there is no trace of it in modern weapons.

I had to do it myself, Chen Tuxin said. As a high school graduate who has passed the federal unified test, this is still difficult to do.

The design is not manual, and a lot of the work that humans do today is done in the simulation chamber. The advent of the simulation chamber can minimize the cost of scientific research, and also reduce the personal danger of scientists in some dangerous experiments.

There is only one place in the city where there is a simulation cabin, and that is the administrative building in the city center. Chen Tu drove to the top floor of the administration building, where there were three simulation cabins. These administrative officials are not interested in such high-tech things. Although it is in the spirit of broadening their horizons, few rats have returned here since the installation.

The guards guarding the simulation cabin were leisurely, and there were few rats on the top floor, so the guards made a homemade old chair. I usually drink tea, read books, and get my salary.

Seeing Chen Tu coming up, the guards were stunned for a moment, it stands to reason that there shouldn't be strangers arriving on this floor. Suddenly, the guards remembered that Chen Tu was the governor of the Cuckoo District, and the guards had seen Chen Tu's portrait. The guard hurriedly put down the teacup in his hand and stood up and saluted a standard military salute.

Chen Tu saw the guard's leisurely appearance just now, and patted the guard's shoulder: "Young man, life is good." However, the duty must be held and resolutely not to let strangers come close. ”

This kind of thing is still to be prevented, although Chen Tu did not say anything critical, but the guards will definitely pay a little more attention than usual.

After entering the simulation cabin, Chen Tu opened the passage and directly located a product called "Ancient Weapons Laboratory". In an era where games are everywhere, some games are as realistic as they are.

Especially this kind of game with a scientific and technological foundation, you really can't play it without a little expertise. What can be achieved in the game, can be done in reality. It is worth mentioning that the weapon machine Kai, which laid the foundation of modern warfare, first appeared in the game fantasy.

The game isn't free, and the labs come and go. To purchase a high-end version of the laboratory, you need 10,000 Earth Coins. If it had been placed in the past, Chen Tu might have only played those normal versions. It's just that now it's different, he doesn't want to play games, but to design a helicopter that can be used in the war of rats.

Looking at some fragmentary design drawings, Chen Tu first designed the engine model. Ancient machines did not originally use source crystals, but a substance called oil. The calorific value of this substance is not high, and it has been gradually replaced since the discovery of the source crystal.

Considering the production capacity of the house, the engine model should not be too advanced, and the loading space of the helicopter is limited, so it is necessary to choose a relatively light engine.

This lightness is relative to Jikai. As a conventional weapon, the engine model of the machine is undoubtedly the most perfect, the current machine Kai has few turbine engines, after the reform of the energy circuit, the photon output changed the original power transmission.

This output is similar to that of optical fibers. The transmission equipment made of special crystals only needs a very thin crystal line to transmit a large amount of energy in a short time, and among the control variables, one of the advantages of the crystal line is the jump transmission, which can change hundreds of times in a few milliseconds.

This time it can be 10,000 electron volts, but the next moment it can output zero electron volts, and in the process, no additional energy is needed to stop the light from escaping.

Therefore, it is not easy to choose a turbo-screw engine from the machine. However, Huang Tian lived up to his wishes. In the midst of his hard search, Chen Tu finally found a 400-year-old engine solution.

This engine is a He-355 power system manufactured by "Qiawu Machinery Power Company", and adopts a reverse double helix power design. This He-355 was originally intended to be used as a power take-off for the Kikai weapon knife.
