The villain also has spring

Yu Wuhen ♂, Miao Yanhao, monthly tickets for reading white books, and mortals began to tip.

-----------------------------------

Wu Chen only found out the details after asking.It turned out that it was also because it was going to be converted into a satellite launch base that Russia sent a large number of experts and engineers to Svobodny before the end.These elite scientists have continued to exert great light and heat in the 20 years after the end of the world.The whole Far East has benefited a lot.Wu Chen looked at it one by one, and the various industrial systems in the Svobodny Remnant Base were classified and quite complete.

Although due to the limitation of space and resources, the output and scale are very low, but it is exactly the sentence: although the sparrow is small, it has all internal organs.

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

What interests Wu Chen the most is the establishment of elite scientists among the elite: Julong Research Ring.

A scientific academy dedicated to the study of dragons.

It's just that compared with the scientifically oriented dragon-type thermal weapons that Wu Chen saw in the fifth settlement, the equipment produced by Yanhuan are all medieval-oriented 'cold' weapons.

Such as keel longbow.

As soon as Wu Chen entered the research environment, he was attracted by a huge compound bow of triple pterosaur bones soaked in a transparent culture tank.

Taking a closer look, Wu Chen found that it was forged from 5, 6, and 7 pairs of dragon ribs. The tops of the ribs and all the joints with the spine were also covered with a beautiful unknown alloy.

"She belongs to Tanya."

Hearing the sound, he raised his head, and the old man in a white research uniform was smiling at him.

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

"Hello, the last sky angel." The old man nodded with a smile.Needless to say, he is also 'pasta'.

"How is this bow made?" Even Clauria's Cyclops couldn't find its splicing point.Is it really natural?

"It's a complicated question."

The old man motioned for the two to come to him, and then pointed to the reagent soaked in the keel compound bow and continued: "A few years after the end of the world, when we ran out of ammunition and food, we accidentally discovered that when the keel was soaked in super-heavy water, the bones Phosphorus and other trace elements will quickly combine to form 'tin phosphor bronze' deposited in the dense voids of the bone, turning the keel into a metal-like sharp and full of toughness."

"The molecular formula of superheavy water is T2O, which is highly radioactive. The usual preparation method is: put metallic lithium in an atomic reactor, and under the bombardment of neutrons, the lithium is converted into tritium, and then combined with oxygen to form superheavy water. It takes nearly ten tons of atomic energy to produce one kilogram of super-heavy water, and the production is very slow. Only a few kilograms of super-heavy water can be produced 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 more expensive than gold times." Claulia quickly explained to Wu Chen.

"The keel was soaked in radioactive super-heavy water..." Wu Chen seemed to see countless radioactive particles penetrating into blood vessels and bones, continuously radiating and strengthening the mutated tissues...

"That's right, although the immersion time prolongs, trace elements such as calcium, magnesium, iron, sodium, potassium, strontium in the bones participate in the reaction one after another, so we have harvested magnesium-aluminum alloys, aluminum-strontium alloys, potassium-sodium alloys, lead Antimony alloys... and many other 'hybrid alloys' made of strange metals that we don't understand. And the bones show magical properties beyond metals."

"Why is it super-heavy water?" Wu Chen couldn't help asking.

"Yes, why is it super-heavy water?" The old man seemed to be muttering to himself, "This is also a problem that has troubled us for more than 20 years. We have tried many methods, even directly bombarding the bull's-eye of the keel with a neutron beam, but all failed without exception. .Only when soaked in super-heavy water can the keel undergo miraculous changes."

"This may be related to the long-term and soft inclusiveness of water." With a long sigh, the old man led the two to another slightly smaller cultivation tank.

Compared with Tanya's golden keel bow, the keel dagger inside is actually glowing with a mysterious dark silver color!

Caressing the beautiful dagger through the box, the old man said again: "Later, we couldn't help thinking, what would happen if the keel was soaked in extremely heavy water?"

"Extremely heavy water refers to the water molecule composed of the radioactive isotope of hydrogen, hydrogen-4, and oxygen. The chemical formula is 4H2O. This molecule may only exist in theory, because the half-life of 4H is 9.93696×10-23 seconds. It is too late to react. It has decayed." Claulia continued popular science.

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

"Phosphorus is still the first to change, and the phosphorus element becomes black phosphorus with a wrinkled honeycomb structure, and then various alloys, until the appearance of nickel-titanium alloys."

"Nitol is a magical memory alloy! A special alloy that can automatically restore its original shape! In addition to its unique shape memory function, it also has excellent characteristics such as wear resistance, corrosion resistance, high damping and superelasticity! Its The expansion rate is above 20%, the fatigue life reaches 1×10 to the 7th power, the damping characteristics are 10 times higher than ordinary springs, and its corrosion resistance is better than the best medical stainless steel at present..." Claulia blurted out.

“我们能给出的数字是：伸缩率200%，疲劳寿命达1×10的70次方，阻尼特性比普通弹簧高100倍。”

"Increased by 10 times." Wu Chen was stunned.Follow the jars on display along the way: greaves, gauntlets, shoulder armor, bras, hot pants, and crowns!

Tanya's figure and this set of protective gear were perfectly integrated, and Wu Chen almost spit out nosebleeds with a puff!

"Is this too little?" Claulia was also surprised.

"Extremely heavy water is too difficult to prepare. This is the result of our best efforts. Now the weapon is soaked in decayed extremely heavy water." The old man understood what Wu Chen was thinking.

"The last question." Wu Chen's face was filled with anticipation, "How did Tanya become Tanya?"

"That's another complication..."

According to the old man's recollection, Tanya's mother, like all the first batch of refugees, escaped from Blagoveshchensk, the capital of the Amur region, to the missile base along the road burned by fire dragons.There is no difference in the early days, except that I can eat more and sleep more than others.Later, when the belly gradually grew, everyone realized that they were pregnant.

Six months later, Tanya was born.She has red hair like her mother.Also super edible like her mother.

He was so hungry that he would eat anything, and once he even disappeared for several days in a row because he was looking for something to eat.Finally, everyone found her sleeping soundly 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 that raised her.

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

It's not scientific at all...

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

There are too many unscientific things.Such as fire dragon.

Regardless of strength, size, explosive power, reproductive ability...all are contrary to the natural laws of the earth.

Frogs can produce hundreds of eggs at a time, and these eggs can grow into tadpoles in a short period of time... while humans can only produce one in a litter, and it takes ten months to conceive.

The species at the top of the food chain should be more difficult to reproduce.

But species like fire dragons, which seem to be stronger than humans, have spread all over the world in just 20 years!

There is only one thing that can match such a terrifying reproduction speed and population destructive power.

virus.

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

Wu Chen also did not give up and asked about hatching dragon eggs. The answer given by the master was the same as that of the scientists in the fifth settlement.Unable to hatch artificially!I'm going, what should I do?Leaving aside the success of capturing a fire dragon intact, even if it can be captured alive, how can it be domesticated?Could it be possible to exchange 1000 points by sending the five flowers to the trading platform?

Obviously impossible.

"Master, can you build some weapons for us?" Shaking his head to clear his mind, Wu Chen decided to settle this opportunity first.

"No problem, it's my honor." The old man smiled very hollow.

Forget about the top-level 'bone and silver equipment', it took 20 years of hard work to make such a set, no matter how stupid you are, you won't sell it. 'Bone Bronze' is already pretty good.Although there is no magical memory function, it can be regarded as the top black technology of this era.

After all, Clauria is a great Cybertronian scientist. She has a deeper understanding of her abilities and body, so she participated in the entire manufacturing process.After Wu Chen saw the final draft of the plan, he was immediately attracted.

The whole shape is a full-body armor of a future female warrior with a sense of science fiction.Beautiful curves, strong armor.The biggest highlight comes from the external weapons loaded on the back:

A pair of 'wings' consisting of a nuclear battery backpack and hypersonic missiles equipped with scramjet engines.The wings connected to the nuclear battery backpack each have only five 'feathers', and the shape of each feather is large enough to be used as a shield, which resembles a miniature version of the American X-51A supersonic aircraft.

Under normal circumstances, the hypersonic missile is in a dormant state, and the five nuclear-electric turbofan engines installed at the root of the wings and the same number of vector nozzles provide sufficient lift for the armor.When necessary, the missile is awakened, and the scramjet engine will instantly break free from the connection with the root of the wing, pushing the missile to blast towards the enemy at a speed exceeding Mach 5.

The huge kinetic energy is enough to destroy everything, and there is no need for additional warheads.Therefore, all hypersonic missiles are actually reduced hypersonic aircraft 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 fighting, it is also equipped with a large cross gun, a compound bow with three folded wings and hundreds of special arrows.Although the base was obliged to serve the Sky Angel free of charge, Wu Chen still paid a lot of commission.

Fortunately, he has earned a lot these days, enough for him to squander.
