The little female soldier who was desperate to find her family became a national hero

In this way, Shen Yiyi quickly became familiar with the staff in the design institute. She was very kind-hearted by nature, so she rushed to do almost everything. Repairing the tree armor weapons that were damaged during the design experiment was Shen Yiyi's forte.

In addition, she is also very beautiful, with the typical appearance of a descendant of the Canglong Kingdom: almond eyes, oval face. Except for her eyebrows that are too upright and not so soft, her overall image is very much in line with the aesthetic taste of these elderly uncles and aunts.

During breaks, everyone would curiously ask Shen Yiyi how she managed to escape from the annihilated border defense corps. Every time she told about her escape process and battlefield experience, everyone was amazed.

Sometimes, when these designers heard Shen Yiyi's creative ideas, they would applaud her and record them down to reproduce them, which made people admire her even more.

Gemini Ruoya was one of those people who particularly admired Shen Yiyi. She was also the other young person in the design institute who did not go to the battlefield.

This beautiful girl in her early twenties had an amazing talent for tree armor materials, but she had a very obvious shortcoming, which was that her hands-on ability was too weak.

He was very good at explaining theories and was also very good at material simulation. But when it came to conducting experiments, he was always in a hurry and lost things, which gave everyone in the design institute a headache.

So after a few accidents, the research institute simply assigned her a team of operators to specifically handle Gemini Ruoya's experimental steps and design and produce some of her genius ideas.

But because of the war, her team had been packed up and sent to the front line. Therefore, she often needed to ask Shen Yiyi for help to verify many things.

"Sister Yiyi, do you have time now?" Gemini Ruoya asked brightly and generously.

Shen Yiyi has a great crush on this girl with long pink hair who likes to print many beautiful flowers on her white lab coat. Although she looks a little confused, the sparks of wisdom she exudes from time to time always make people applaud.

Shen Yiyi also responded immediately: "We have time. What? Do you want to verify some weapons again?"

"I'm not asking you to verify the weapon this time," Gemini Ruoya walked closer to Shen Yiyi: "It's a bit embarrassing to say this, I just want you to help me tidy up my personal space."

She said sorry, but she was not polite at all with her hands. She pulled Shen Yiyi towards her exclusive laboratory.

As soon as she entered the laboratory, Shen Yiyi was dumbfounded. Although she had helped Ruoya with weapon verification work before, she had never been in this laboratory because of its high confidentiality.

But this time, after getting the permission, my first feeling when I came in was: This place is really, really messy! Ah!

This room is as spacious as the lobby on the first floor. Rather than calling it a research room, it is more like a unique space that combines the elements of a utility room and a museum.

The interior of the space is intricately furnished, and the floor is filled with a variety of equipment, material samples, and various experimental instruments.

What is even more eye-catching is that various types of tree armor equipment and weapon parts, from individual armor to medium-sized tree armor, occupy more than half of the room in a messy but orderly manner. There are both finished fine products and semi-finished products still in production.

Among the dazzling array of displays, the most eye-catching one is a complete tree armor in the depths of the hall. Standing there, it does not look like a cold war machine, but more like a dazzling art treasure.

Its surface abandons the conventional wood texture and is instead covered with an indescribable alloy. The material of the protective armor plates at the joints is even more mysterious, like crystal shells. The overall color presents a soft light pink luster, with faint golden stripes flowing on it, looming and dreamy.

Its size is between that of a single-soldier armor and a medium-sized tree armor. It is neither purely insect-like or animal-like, nor completely human-like. The folding wings on its back add a bit of mystery and strangeness to it.

What kind of tree armor is this? Is it used for land combat? Coastal support? Or an aerial reconnaissance weapon? Confused, Shen Yiyi looked around the tree armor curiously, while Twin Ruoya proudly introduced it: "This is a tree armor that can transform." Hearing this, Shen Yiyi's heart moved, but she was also a little cautious.

The concept of transformable tree armor has caused quite a stir in the military field. People have imagined an all-around combat machine that can walk on land, spread its wings and fly, and even transform into a ship to cross the ocean.

However, with the birth and practical testing of multiple models, people gradually found that this all-round tree armor often cannot take into account various performances in actual applications. The solid defense required for land warfare, the flexible maneuverability in the air, and the strong reconnaissance and survivability at sea are all difficult to be perfectly reflected in the deformable tree armor. Therefore, this concept has gradually become a topic of conversation after dinner.

Seeing the hesitation flashing in Shen Yiyi's eyes, Gemini Ruoya felt a little aggrieved. She held Shen Yiyi's arm tightly, like a child who took out a new toy but didn't get any praise, and eagerly explained: "Sister Yiyi, don't underestimate it! This is the most advanced tree armor I designed myself. It is different from those failed products in history!" After that, she shook Shen Yiyi's arm excitedly, with unquestionable determination and persistence in her eyes.

Shen Yiyi couldn't help laughing at her innocent and cute appearance, and teased her deliberately: "Oh? Better than those previous pieces of trash? Doesn't that mean that the one you designed is a 'little trash'?" As soon as these words came out, Gemini Ruoya was immediately furious and bit Shen Yiyi hard to vent her anger.

After biting it, she was still not satisfied, so she turned her head away angrily, reached out to pull off the parasitic vine wrapped around her neck, and threw it hard at the dazzling tree armor.

The moment the vine touched the armor, the tree armor that had been as quiet as a virgin seemed to be injected with life and became active. It slowly squatted down, revealing a human-shaped entrance.

Gemini Ruoya jumped in nimbly, and as the entrance slowly closed, she left a coquettish complaint: "Sister Yiyi, you are a big bad guy! I want to open your eyes!" Then, the armor's transformation mechanism began to slowly unfold, and an unprecedented, subversive visual feast slowly unfolded in front of Shen Yiyi's eyes.

With the skilled operation of the twin Ruoya, Shen Yiyi was completely shocked by the scene before her eyes. The joint armor, external armor, and internal skeleton of the tree armor seemed to be touched by a magic hand, breaking into countless tiny flakes like fallen leaves in autumn, and then these flakes quickly shrank behind the tree armor like compressed sponges, and finally disappeared without a trace.

Then, the tree armor began its gorgeous transformation. The original pink and gold color seemed to be summoned by a mysterious force, gradually flickering and changing, flowing like a rainbow, and finally the entire tree armor was shrouded in deep black, like a black hole in the night sky, swallowing up all light and color.

Soon, the limbs and head of the tree armor folded smoothly and merged into the armor body as if guided by magic. The process was as natural as solid grease being melted by the high temperature in an oven, and as natural as water flowing without a trace.

In just one eighth of an hourglass' time, the once majestic tree armor had disappeared, replaced by an extremely huge and round black pebble body that was nearly two people tall. It lay there quietly like a black pearl in the night sky, emitting a mysterious and deep light.

"Oh my god, this is amazing." Shen Yiyi was amazed. She stared at the black pearl tightly, as if she wanted to see through the mystery inside. "It turned out to be a precious solid-liquid dual-state material."

"Stinky sister, it's not over yet. Today I will make you convinced!" Ruoya's mischievous voice came from inside the tree armor, breaking the moment of silence.

With a light snap, the black pearl instantly split apart, and its limbs quickly popped out like bamboo shoots, returning to its human form. At the same time, the outer armor that had just shrunk and folded also spread out from behind the tree armor like wings, quickly covering the entire body.

At this moment, the tree armor is no longer the gorgeous work of art it once was, but a fighting machine full of power and deterrence.

Shen Yiyi widened her eyes in astonishment again, "Oh my God, this solid-liquid dual-state material actually has memory properties, how much wealth would this cost!" This material, which has both solid and liquid forms, is more expensive than the same weight of gold.

Afterwards, this tree armor transformed into various forms including standard land combat tree armor, medium-sized iron bird, mini sky whale, civilian land vehicle, etc., each of which showed its diversity and magic.

When the tree armor returned to its original form, Ruoya opened the hatch from the middle and asked proudly: "How is it, stinky sister? Do you still think it's useless now?"

At this time, Shen Yiyi was so shocked that she couldn't speak. After a long time, she rubbed her eyes and said with a hint of sarcasm: "I'm not sure whether it is waste or not, but I'm sure you are very rich. With so many solid-liquid dual-state materials, I'm afraid you can buy an island, right?"

Gemini Ruoya gritted her teeth again when she heard Shen Yiyi's words, and seemed to be dissatisfied with Shen Yiyi's ambiguous answer. So she signaled Shen Yiyi to test the hardness of the tree armor to see if it was really as weak as the legend said.

Shen Yiyi walked towards the hardness tester with some curiosity. In her opinion, although solid and liquid materials have attractive appearance and are varied, they are often lacking in hardness.

However, when she saw the samples made of the same material as the tree armor, her concept was completely overturned. The values ​​on the test bench were incredible, with a hardness twice that of the hardest known wood, northern white quebracho, and only half the weight.

The unique ductility of this liquid-solid-liquid material brings infinite possibilities to this tree armor. Not only can it switch freely between different forms, but it can also maintain such strong defense, which is simply a miracle!

Shen Yiyi was completely shocked. She stared at the data in front of her with wide eyes, her heart filled with respect and admiration.

"Okay, I admit that this thing is not trash. It is the best tree armor I have ever seen." She said sincerely, "Xiao Ruoya, I apologize to you. I did look down on your work before."

Hearing Shen Yiyi's apology and praise, Gemini Ruoya finally revealed a satisfied smile. "Ahahahaha!" She laughed heartily without any image, her laughter full of pride and smugness.

While the twins Ruoya were still immersed in joy, Shen Yiyi hurriedly asked: "What is the material of this tree armor? Is it derived from plants or forged from metal? I have observed it carefully, but I can't find any traces of assembly. If it is grown naturally, then this material is too magical."

Talking about her masterpiece, Gemini Ruoya pulled Shen Yiyi to sit down with great interest and told the story: "This is the solid-liquid two-state material I invented recently. It can simulate multiple states such as liquid, plant and metal, and the conversion speed is amazing. It is because of this discovery that I was kept in this experimental building and did not go to serve on the front line."

After saying that, Ruoya tapped the water mirror on the table and opened a document. "This material combines the advantages of ordinary solid-liquid two-state materials, but abandons its disadvantages of hardness and softness. Of course, the price is naturally much higher than that of ordinary two-state materials."

"Then which plant is this material extracted from?" Shen Yiyi asked curiously.

Gemini Ruoya pointed to an inconspicuous pot of green plants on the desk and said, "The birth of this material is inseparable from a special animal. Come closer and take a look." Shen Yiyi followed Ruoya's gesture and took a closer look. She saw several snails as big as half a fingernail lying leisurely on the leaves.

"These snails are only found in the Beidi Plateau near Sanjiangyuan City. Their numbers are extremely rare and they feed on soil. The local soil and stones are rich in extremely hard metal particles, which undergo unique changes after being digested and absorbed by the snails. In the end, they excrete the original form of this solid-liquid dual-state material out of their bodies in the form of excrement."

Shen Yiyi suddenly realized and asked, "In other words, this solid-liquid dual-state substance is the biological cells of the snail that make the metal in a liquid state, and when the biological cells are forcibly isolated, this metal similar to biological fluid will return to a solid state."

Shen Yiyi thought for a moment and continued, "Although the snail's body fluid can change the form of metal, this metal is originally an excrement that it cannot absorb, so it avoids the phenomenon of biological cells swallowing the metal. Then mix the memory particles to accelerate the change process, and then this solid-liquid dual-state substance is produced, right?"

"That's a very accurate answer!" A voice suddenly sounded from behind Shen Yiyi. She turned around and saw that it was Dean Maria. The lady patted her shoulder with a smile on her face and said, "Your ability to understand is impressive. All the staff in the institute are full of praise for you. It seems that it is a bit of a waste of your talent to just let you serve as an experimental operator."
