The members of the search team standing at the edge of the pit were happy, Zeng Tianqi gave up another textbook-style actual combat exercise, and the figure of the seven people flying over made all the onlookers open their eyes. Wrapped in bandages, Zhuanghachi hungrily captures everyone's movements and skills. At first, they were worried that Zeng Tianqi would be in danger with one enemy and six enemies, but slowly they found that Zeng Tianqi was not only at ease, but these six people could not hurt Zeng Tianqi no matter what, at most, the dagger and bullet hit Zeng Tianqi's dark red right arm and burst out of sparks, as well as the dangerous hugging action, the sharp tooth-like short blades that popped out between his arms were all dodged away by Zeng Tianqi one by one, Zeng Tianqi has a terrible talent for fighting, he once said, any weapon, as long as you see the form, Its attack form and attack route are also predictable. So he chose the knife, because the knife is the courage of a hundred soldiers, and it can be crushed in a grand manner, even if he knows the attack route, he only needs to run it strongly, and he will shock his mind.

The battle lasted only a few minutes, and when Zeng Tianqi threw down the 'hostage' with the charred head, only the black mask with the bow was left on the field. He was about to turn around and flee, only to see Zeng Tian abandon the spot and flash, catch up with him in a few steps, boom, his right hand hit the back of his neck, the neck was broken in response, and it was blasted into the dirt with half of its head and body, and stopped moving.

The Black Mask 'Weapon' team is all wiped out!

The dark red of Zeng Tian's right hand gradually disappeared, and he walked over to the chain mask where he had smashed his head, and retrieved a key from him that looked like a toothed USB flash drive. Inserting the lock cylinder, I heard a tick, and the lock on my right arm popped open and fell to the ground.

Li Yiyan looked at Zeng Tianqi's right hand that was slowly cooling and blackening, trembling all over, cold sweat broke out, he lost his protective clothing, and the back of his thin shirt was full of sweat in the air. In his eyes, these 'weapons' are the murderous and unblinking new humans cultivated by Ji Donglai, with a high degree of execution, cold-blooded and dangerous. In the face of the siege of six people, Zeng Tianqi was killed one by one in the blink of an eye like beating a child. It was more dangerous and violent.

"Pack up and take Dr. Li down to settle down." After Zeng Tianqi finished speaking, he walked in the direction where the Black Mask and the others came without looking back.

As he expected, about a mile away from the wreckage of Sky III, a black Iron Raven helicopter stopped in the valley. The Iron Jay is a special model of heavy armed helicopters in Dongguo, with double-sided rotors, and the overall appearance of a streamlined flat state, with certain stealth functions, is a special helicopter for special operations.

"Ji Donglai really has a lot of good things, Zeng Tianqi looked at the equipment and materials in the tail cabin, guns, knives, explosives, bows, crossbows, combat suits, diving suits, etc.

Zeng Tianqi looked at these exquisite equipment, and he suddenly felt that the wreckage of this Sky III was even more valuable than he imagined.

Boom, another half an hour of cutting, the heavy laboratory door embedded in the space station finally broke. A small laboratory was revealed, and to the left of the laboratory, a strange machine took up nearly half of the space of less than 7 square meters. Zeng Tian stepped in and carefully inspected the machine.

At one end of the machine there is a special mechanical plier, and the complex arthropod has been believed to be able to make three-dimensional rotation without dead ends. At the other end of the machine, there is no milling cutter structure, but a well tip cone like a transmitter composed of several lenses. The main part of the machine is not large, and the main thing that occupies space is several barrel-shaped equipment in the middle of it and a beautiful magnetic coil. The whole machine is like the abdominal cavity of a huge animal, and the magnetic coil is propped up in the middle like a rib.

Zeng Tianqi lowered his body, he touched a button under the machine tool, pressed the button, and a narrow mezzanine at the bottom of the machine tool popped out. It is a flat, rectangular box with two transparent glass tubes lying in the inner lining of the box. Zeng Tianqi's eyes suddenly flashed, and there were four special glass tubes lying neatly in the box, and one side of the glass tube was also connected to a transparent polymeric material tube, and the glass tube was filled with a substance that flashed dark blue metallic luster in black. If he guessed correctly, the black and blue tube is a rare metal produced in the deep-sea chrome ore of the Lost Sea, when this metal is extracted, it is like a fluid that can flow slowly like slightly viscous mercury, and the dark blue luster is its trademark, this metal is mysterious because it has no hardness and is very easy to oxidize, but after mixing with another liquid magnetic metal, it will become the world's most high-temperature resistant and hard-to-deform inert alloy - Stylo alloy, Abbreviated as STL.

The dark blue rare metal is extremely difficult to purify, they have existed for tens of millions of years, if not hundreds of millions, of years, in the trillions of tons of water pressure in the Lost Sea, and this chrome ore has been shown to contain DTL's blue material only in lava deep in the earth's mantle. They are mixed under high pressure and with chromium deposits to form a dense basalt that is difficult to separate even with the best centrifugal separation techniques, let alone the purification process after separation. Therefore, the so-called Stello alloy on the planet is not STL in the true sense of the word, and the highest purity SLT known on the ground is mixed with at least 20% of impurities such as chromium, carbon, and iron. However, the hardness of the highly condensed carbon has been surpassed in the test.

Therefore, some scientists hope to try to make a real high-purity STL in a vacuum and gravity-free environment, because even a little bit of this thing is enough to change the current industrial system and make a qualitative breakthrough. Needless to say, if high-purity STL can be injected into the most precise mold, the result is the most precise milling cutter on the planet that will hardly wear out, and then cast the suspension wheel of the motor, then it can be processed almost below microns, and even nano-level instrument physical micro-carving, which can improve the precision technology elements on the planet by several orders of magnitude.

Moreover, the most amazing thing is that once the SLT alloy is formed, it not only does not deform, but also superconducts at room temperature. These large bottles of STL alloy raw material are definitely a shocking asset before the end of the world. Because even in the current environment of planetary gravity, the synthetic STL alloy has crushed all the known species of alloy on the planet with its anti-heaven performance.

Once Dongguo has done a test, STL with 30% impurities under the cutting of hundreds of millions of joules of plasma laser, STL shows extremely rapid heat conduction and ultra-stable physical form, so that in a short time, even a super-power ion cutting machine can not easily cut a pencil thickness of STL alloy, and a huge amount of heat will be quickly dissipated into the surrounding space.

And it was also this plasma experiment that surprised scientists to find that after plasma cutting STL, various metal impurities in it have undergone subtle changes. That is, it was purified. This discovery was immediately included in the red-headed top-secret documents by Dongguo, and even the top of Dongguo's scientific and technological community knew very little. Of course, Li Yiyan is excepted, because the entire plasma purification process is a prototype made under his auspices, that is, the super-II ion bed in front of him.

Of course, Zeng Tianqi knew about this alloy, and even secretly investigated this alloy back then, although he didn't know how these STL raw materials were purified, but he still had the ability to identify. There are at least more than 40kg of liquid metal in the four bottles in front of him, and he has learned from his previous investigation that the higher the purity of the chrome ore associated metal, the better its fluidity, and even gradually change from the original red black to dark blue.

Zeng Tianqi was a little ecstatic, these bottles of STL in front of him, coupled with this plasma machine tool, will become a huge cost for the future development of Shucheng. In the future, there is so much that can be done with this machine and these STLs.

He immediately found Li Yiyan, and Li Yiqi carefully inspected the machine tool at the moment. It's just a pity that there is no high-power power power that can be turned on, and he can't judge whether it is intact or not. Next, he looked at the four large dark blue glass tubes that Zeng Tianqi put away. Li Yiyan swallowed his saliva, and before he could speak, Zeng Tianqi took the lead and said:

"Dr. Li, let me introduce myself again, Zeng Tianqi is currently the city lord of Tree City, a human shelter in the Naple district of the plateau. This machine tool belongs to Tree City. Zeng Tianqi, the search captain of Cloud Hidden City, on behalf of Yun Yin, invited Dr. Li to join Cloud Hidden City. Cloud Hidden City, no matter now or in the future, has an important place for you. After speaking, Zeng Tianqi stretched out his left hand to Li Yiyan.

"This 。。。。。" Li Yiyan couldn't cry or laugh, the original plan was to find both parts of the Aerospace III fracture, on the one hand, he would recover the 'ion bed' to the Central Council, and on the other hand, Ji Donglai's Special Operations Department would recover the collector. Now that Cheng Biting Jin has been killed halfway, a 'Cloud Hidden City' has fallen from the sky and cut off half of the Sky III, and he is now also exposed to X gamma radiation, not to mention whether he can return to the center alive, even if he goes back, without the 'ion bed' in his hand, he has lost his value to the Central Council.

The ion bed was made by him and his teacher, in which he only solved the problem of the plasma emitter and the design of the plasma electromagnetic purification bed frame, and the overall structure was designed by his teacher.

Moreover, it is impossible for him to return to Shudi, which fell out with the center in the second month after the catastrophe and has long been out of the jurisdiction of the center. Besides, without a driver, he wouldn't be able to drive even if the Iron Raven gave it to him.

Li Yiyan hesitated again and again, the weapons action team was completely wiped out, and his protective clothing was torn off by Zeng Tianqi, no matter which way you look at it, what was left for him was a dead end. In the end, he had to take a fresh look at the young man in front of him. In the end, he still stretched out his hand to hold Zeng Tianqi's hand, and stayed in the so-called 'Cloud Hidden City', which might be the best choice for him for the rest of the time.

Zeng Tianqi was not surprised that Li Yiqi would agree, because there was only this way in front of this poor scientist. From the time he tore Li Yiyan's radiation-proof coat, he had already made up his mind.

"Dr. Lee understands the righteousness, and you will soon find out that you have made the best choice." Zeng Tianqi held Li Yiyan's hand and gently put a tube of pale green 'gene stabilizer' in the palm of his hand. He winked mysteriously at Li Yiqi and grinned.

"Zhuangzi, you first listen to Dr. Li's command here to tear down this 'room' inside. After it was demolished, the family home came to me, and we arranged it again. Lao Ge, take your people with me. ”

After Zeng Tian gave up, Li Yiyan was in a daze pinching the stabilizer, and Zhuang Ba stepped forward to look at the thin and thin Li Yiyan while greeting people and said, "Dr. Li, you'd better take it as soon as possible." Otherwise, tomorrow ... You're probably going to go berserk. ”

Li Yiyan came back to his senses and asked Zhuangba who was walking by, "What is this??" ”

Zhuang Ba turned his head and smiled, pointed to the sky, and said, "We, Dr. Marin, developed an evolutionary potion. You know what? Dr. Li, not everyone can get it in Cloud Hidden City. This is the biggest reliance we can rely on to fight with God. ”
