Rain without a trace ♂, Miao Yanhao, a monthly pass to read a white book, and mortals. The first tip-

Wu Chen asked before he knew the specific story. It turned out that it was also because it was to be converted into a satellite launch base, so Russia sent a large number of specialists and engineers to Svobodny before the end of the day. These elite scientists have continued to exert tremendous light and heat for the 20 years after the end of the world. The Far East as a whole has benefited enormously. Wu Chen has seen it in turn, and the various industrial systems of the Swobod Remnant Base are classified and quite perfect.

Although the production and scale are low due to space and resource constraints, it is in line with the sentence: although the sparrow is small, it has all kinds of organs.

Weapons and ammunition are self-sufficient, no wonder they can continue to fight for 20 years.

What interests Wu Chen the most is the one formed by the elite scientists among the elites: Julong Yanhuan.

An academy of sciences specializing in fire dragons.

It's just that compared to the scientific-oriented dragon thermal weapons that Wu Chen saw in the fifth settlement, the equipment produced by Yanhuan is a medieval-oriented 'cold' weapon.

For example, the keel longbow.

As soon as Wu Chen walked into the research ring, he was attracted by a huge three-fold pteroterodactyl keel compound bow soaked in a transparent culture tank.

After a closer look, Wu Chen found that it was forged from a combination of 5, 6, and 7, three pairs of fire dragon ribs, and the top of the ribs and all the connections with the spine were also wrapped in beautiful unknown alloys.

"She belongs to Tanya."

Hearing this, he raised his head, and an old man in a white scientific research uniform was smiling at him.

"Hello, Master." Wu Chen unconsciously used the title of fantasy.

"Hello, the last empty angel." The old man smiled and nodded. Go without saying. He is also 'hollow powder'.

"How is this bow made?" Rao was Gloria's laser eye, and he couldn't find the splicing point of it. Is it really natural?

"It's a complex issue."

The old man motioned for the two of them to come to him, and then pointed to the reagent used to soak the keel compound bow and continued: "In the first few years after the end of the world, we stumbled upon the stumbling when we had exhausted our ammunition and food, when we soaked the keel in super-heavy water. The phosphorus and other trace elements in the bones will quickly combine to form 'tin phosphor bronze', which is deposited in the dense voids of the bones, turning the keel into a metal-like sharp and resilient one. ”

"The molecular formula of supergravity water is T2O, which is very radioactive. The usual method of preparation is to put lithium metal in an atomic reactor and turn the lithium into tritium under the bombardment of neutrons. It is then oxidized to form super-heavy water. It takes nearly ten tons of atomic energy to make one kilogram of super-heavy water, and the production is very slow, only a few kilograms of super-heavy water can be made in a year, so the price of super-heavy water is tens of thousands of times more expensive than heavy water, and hundreds of thousands of times more expensive than gold. Gloria quickly gave Wu Chen a popular science.

"Radioactive superweight water soaked keel ......" Wu Chen seemed to see countless radioactive particles burrowing into blood vessels and bones. Constant radiation strengthens mutant tissues......

"That's right, although the soaking time is extended, calcium, magnesium, iron, sodium, potassium, strontium in the bones ...... and other trace elements participated in the reaction one after another, so we harvested magnesium-aluminum alloy, aluminum-strontium alloy, potassium-sodium alloy, lead-antimony alloy...... There are also many 'hybrid alloys' that are made from a mixture of magical metals that we cannot comprehend. And the bones also showed magical properties that surpassed those of metal. ”

"Why super-heavy water?" Wu Chen couldn't help but ask.

"Yes, why super-heavy water." The old man seemed to be muttering to himself, "This is also a problem that has plagued us for more than twenty years. We tried many methods, even bombarding the bullseye of the keel directly with neutron beams, but all of them failed. Only by soaking in super-heavy water. The keel will change magically. ”

"It may have something to do with the long-term and soft inclusiveness of water." With a long sigh, the old man led the two of them to another, slightly smaller tank.

Compared to Tanya's golden dragon bone bow, the dragon bone short sword in it was actually glowing with mysterious dark silver!

Stroking the beautiful dagger through the box. The old man said, "Later, we can't help but think, what will happen if we soak the keel in extremely heavy water? ”

"Extremely heavy water refers to a water molecule composed of hydrogen, the radioisotope hydrogen-4, and oxygen, with the chemical formula 4H2O, which may exist only theoretically. Because the half-life of 4h is 9.93696x10-23 seconds, it has already decayed before it has time to react. Gloria continued to popularize science.

"But they did." All of Wu Chen's eyes were attracted by this magical dagger. Because his brain waves are sensing the complex energy network inside like veins!

"The first thing to change is still phosphorus. The element of phosphorus becomes black phosphorus with a folded honeycomb structure, and then various alloys. Until, the advent of nitinol. ”

"Nitinol is a magical memory alloy! Special alloys that automatically restore their original shapes! In addition to its unique shape memory function, it also has excellent features such as wear resistance, corrosion resistance, high damping and super elasticity! It has a contraction rate of more than 20%, a fatigue life of 1x10 to the 7th power, 10 times higher damping characteristics than ordinary springs, and its corrosion resistance is better than the best medical stainless steel ...... available," Claudia blurted out.

"The figures we can give are: 200% expansion and contraction, fatigue life of 1x10 to the 70th power, and damping characteristics 100 times higher than ordinary springs."

"It's a 10-fold increase." Wu Chen was stunned. Look along the culture tanks on display: shin guards, gauntlets, shoulder armor, bras, hot pants, and tiaras!

Tanya's figure number jù and this set of protective gear that can not be less perfectly integrated, Wu Chen almost spurted out a nosebleed with a pop!

"That's too little, isn't it?" Gloria was also surprised.

"Very heavy water is too difficult to prepare, and that's what we've done to get it out of our best hands. Now soaking the weapon is the extremely heavy water after decay. The old man understood what Wu Chen was thinking.

"One last question." Wu Chen's face was full of anticipation, "How did Tanya become Tanya?" ”

"It's another complicated issue......"

According to the old man's recollections, Tanya's mother, like all the first refugees, fled to the missile base from Blagoveshchensk, the capital of the Amur Region, along the road burned by the dragon. It was no different at first, except that it was more edible and sleepy than others. Later, when the belly gradually got bigger, everyone knew that she was pregnant.

Half a year later, Tanya was born. He has red hair like his mother. It's also super edible like her mother.

I was so hungry that I ate everything, and once I was missing for several days because I was looking for food. In the end, everyone found her sleeping in the belly of a fire dragon corpse outside the base.

That's right, she ate the dragon's entrails.

Including dragon eggs.

What happened later was simple, from killing the first dragon at the age of nine, to today's 501st, in a sense, it was the fire dragon who raised her.

"Can you really make up for what you eat?" Wu Chen was messy.

It's not scientific at all......

Why turn a blind eye to such an unscientific event, Wu Chen can understand the feelings of scientists.

There are so many unscientific things. For example, the fire dragon.

Regardless of strength, size, explosiveness, reproduction ability...... are contrary to the laws of nature on earth.

Frogs can lay hundreds or thousands of eggs at a time, and these eggs can grow into tadpoles in a short period of time...... Most human beings can only give birth to one child, and they have to conceive in October.

The more species that stand at the top of the food chain, the more difficult it is to reproduce.

But a species like the fire dragon, which seems to be more powerful than humans, has spread all over the world in just 20 years!

With such a terrifying speed of reproduction and population destruction, only one thing can match it.

Virus.

That's right, the fire dragon is the virus of the world, the plague of the earth.

Wu Chen also asked about the hatching of dragon eggs, and the answer given by the master was the same as that of the scientists in the fifth settlement. Artificial incubation is not possible! I'll go, what can I do? Not to mention the success of capturing a fire dragon alive intact, even if it can be captured alive, how should it be domesticated? Could it be that if you send it to the trading platform, you can exchange it back for 1,000 points?

Apparently impossible.

"Master, can you make us some weapons?" Shaking his head and emptying his mind, Wu Chen decided to deal with the opportunity in front of him first.

"No problem, it's my pleasure." The old man smiled very hollowly.

Even if the top-level 'bone silver equipment' is forgotten, it took 20 years of hard work to create such a set, and no matter how brain-dead it is, it will not be sold. 'Bone-copper' is already very good. Although it doesn't have a magical memory function, it can be regarded as the top black technology in this era.

After all, Gloria is a great Cybertron scientist, and she has a deeper understanding of her own abilities and body, so she is involved in the entire manufacturing process. Wu Chen read the final draft of the plan and was immediately attracted.

The whole shape is a full-body armor of a futuristic female warrior with a sense of science fiction. Curved and tough. The biggest highlight comes from the plug-in weapons loaded on the back:

A pair of 'wings' consisting of a nuclear battery backpack and a hypersonic missile equipped with a scramjet engine. The wings attached to the nuclear battery backpack have only five 'feathers' each, and each feather is large enough to be used as a shield, resembling a miniature version of the U.S. X-51A hypersonic vehicle.

As a rule, hypersonic missiles are dormant, and the armor is provided with sufficient lift by five nuclear turbofan engines installed at the base of the wings, as well as an equal number of vector nozzles. Wake up the missile if necessary, and the scramjet engine will instantly break free from the wing roots, propelling the missile to blast at the enemy at a speed of more than Mach 5.

The huge kinetic energy is enough to destroy it, and there is no need for another warhead at all. Therefore, all hypersonic missiles are actually shrunken hypersonic vehicles without warheads in the usual sense.

There are a total of 10 nuclear turbofan engines, 10 vector nozzles, and 10 hypersonic missiles on the two wings. In order to cope with the fight, it is also equipped with a large cross gun and a triad-wing compound bow, as well as hundreds of special arrows. Although the base is obliged to serve the empty angels free of charge, Wu Chen still pays a lot of commissions.

Fortunately, he has made a lot of money these days, which is enough for him to squander. (To be continued) R580
