Lin Dan was full of curiosity about the doctor's gift. After taking Lu Yun to the training ground, he stared at the box with his clear eyes, and couldn't help rubbing his hands, like a child waiting to split the Christmas gift.

The first time Lu Yun saw her childlike side, he was amused. His eyes turned, but he found that Nie Ting and Luo Yuheng were looking at her with a focus, with their expressions being gentler than the other, and he couldn't help but become nervous. Doctor, a guy with low emotional intelligence, had a crush on Lin Dan but was not proactive. He even put this big fat piece of meat next to the mouths of the two wolves. He wouldn't think about it for the rest of his life, right?

While thinking about it, she opened the password box and took out a silver-white metal bracelet. The surface of the bracelet was very smooth and flat, and only a transparent crystal core the size of a pigeon egg was inlaid in the middle.

"The crystal core of the spiritual zombie king?" Lin Dan was not unfamiliar with this thing at all, because the doctor just gave her one not long ago.

"No, no, no, this is not a zombie crystal core," Lu Yun quickly explained: "This is a crystal core synthesized by our doctor himself. It has the function of storing energy and transmitting mental power. Do you don't know the mental power, right? It's the idea, everyone has this thing, so everyone can use this bracelet. Lin Dan, if you wear it, I'll tell you the specific usage."

The person Lin Dan trusted the most is the doctor, and she would not even doubt his subordinates. She put on a bracelet and gently brushed the artificial crystal core with her fingertips, and her heart was filled with shock. No one had ever touched the crystal core of the Zombie King, so she didn't know how surging energy it contained. However, Lin Dan hugged it and went to sleep every night, so she naturally knew how unique it was. She thought it was the most precious treasure in the world, unique and irreplaceable.

But now, she touched the artificial crystal core with her mental power, but was shocked to find that it was no different from the Zombie King Crystal. It also has surging energy, indestructible texture and dazzling light. If even the Zombie King Crystal Core can be synthesized, what else in this world can't be done by a doctor?

But no one present knew how to use his mental power except her, so naturally he could not discover the secret of this artificial crystal core. Without using mental power tentacles to explore it, no one would know what kind of terrible secret is hidden under its hard shell.

Lin Tan's throat was so dry that he once again felt deeply that he couldn't understand the doctor. The word "unfathomable" was not enough to describe his strength.

Lu Yun did not notice Lin Dan's abnormality at all, and explained carefully: "The word mental power was invented by a doctor. I am not very clear about how to use it. Anyway, you just need to wear this bracelet, press the artificial crystal core with your palm, and empty your head for two to three minutes. After that, it will naturally start to operate."

"What is the purpose of this thing?" Luo Yuheng said that he couldn't understand at all.

"Brother, this is a piece of jewelry. It is natural for men to give women jewelry." Luo Yuyan said firmly.

Nie Ting did not express any opinions on this. As long as Lin Dan liked it, he would care what others would give him.

Lu Yun was almost amused by Luo Yuyan's silly white sweetness, but he had to hold back. When Lin Dan activated the bracelet, she suddenly summoned a fireball and threw it at the other party. The fireball was white, and the extreme high temperature evaporated and twisted the air. This shows that Lu Yun is a master at level seven or above.

She was only an arm away from Lin Dan and did not release her murderous aura at all, so Lin Dan was not prepared and had no time to hide. Nie Ting and Luo Yuheng, who were standing a little further, wanted to save him, but it was almost time.

When the fireball hit near, Lin Dan subconsciously raised his hand to protect his head and face, but unexpectedly the bracelet flashed with a dazzling white light, and then instantly turned into a metal shield, blocking her fatal attack. The fireball of thousands of degrees could almost dissolve any metal, but there was no way to use the shield. It shattered into Mars with a bang, and then fell and extinguished.

Lin Dan raised his head slightly, and the shield seemed to have sensed and immediately changed back to the shape of a bracelet. If the ground had not been burned through several large holes by high-temperature Mars, black smoke was slowly emitting black smoke. Lin Dan would have thought that everything just now was an illusion. She stared at the bracelet, her eyes emitting light bit by bit.

Lu Yun was full of pride. He was about to explain the purpose of the bracelet, but Lin Dan turned his wrist and directly controlled the bracelet to turn into a pair of silver-white armor, covering her right arm. She punched the ground, smashing a large pit half a meter deep, and then raised her hand to turn the armor of the knuckles into four long blades, cutting through the hard cement wall. Without explanation at all, she spontaneously explored the role of the bracelet, and quickly mastered its attack power and defense power.

Lu Yun couldn't even say a word, so he could only stand aside and applaud Lin Dan. No matter what field he was in, the big guy was always the big guy. When she found that Luo Yuheng, Luo Yuyan and Nie Ting showed stupid expressions, she finally found a little superiority and explained: "This is our doctor's latest research and development project - biochemical armor, which is synthesized by sensing devices, liquid metals and regenerated biological cells. It is a weapon. Anyone can wear it, but the effect varies from person to person. Some people have strong sensitivity and great effect; some people have weak sensitivity and little effect, but the basic defense is completely enough. After all, there are only a few people who have put their functions to the extreme."

As soon as Lu Yun finished speaking, Lin Dan suddenly raised his fist and attacked Nie Ting, and four sharp blades flashed on her bones and joints.

Nie Ting immediately condensed a thick steel plate to block her attack, but saw four sharp blades piercing the steel plate directly, cutting it into pieces like a knife cutting tofu. Its sharpness is far beyond everyone's imagination.

After Lin Dan scratched the steel plate, she stopped attacking and looked at the bracelet that returned to her initial state with a shiny look. This thing was made up for her and made up for her shortcomings. From then on, she was not worried about whether it was long attack or close combat. Whether it was attack power or defense, she had no blind spots, so why did she have to worry about being discovered by others?

"I like this gift very much!" she said sincerely.

Nie Ting took two steps back and smiled slightly.

Luo Yuheng definitely thought the most and the most complicated thing, and immediately asked: "Can everyone use this bracelet? Including ordinary people?"

"That's right." Lu Yun said firmly.

"Is the cost high? Can it be produced without energy?"

"The cost is naturally high, and mass production is difficult. After all, Dr. Lin's bracelet uses the best workmanship and the best raw materials. In fact, we also have low-end versions, which are not as powerful as that, but they can also turn ordinary people into powerful and invulnerable enhancement abilities." Lu Yun explained patiently.

"The low-end version is already very good! I want to meet the doctor and ask him if he can mass-produce low-end versions of biochemical armor. This is a major event that benefits the country and the people. With this kind of armor, the chance of survival of human beings will be greatly improved. Not only psychics, but also ordinary people can defeat this desperate world, do you know?" Luo Yuheng's face was full of excitement.

"Then I'll ask the doctor after I go back and then contact you." Lu Yun nodded slightly and prepared to say goodbye: "Doctor Lin, I'll leave first, and I'll come to play with you if I have the chance."

"Okay, please thank the doctor for me. I like this gift very much." Lin Dan said sincerely. She seemed to owe the doctor a huge favor. When will she pay it back in her life? Forget it, I will pay it back in my life. Anyway, I will pay it back in my life.

Thinking of this, she bent down again and thanked her sincerely.

Lu Yunlian said he was welcome and left in a hurry. She knew that a major change would radiate from Base No. 1 to the whole country and even the whole world.

At the same time, Liu Ye was walking into a large underground research institute, and beside her was Bu Mo, the head of Base No. 3.

"Are you sure that Dr. Ma's scientific research ability is stronger than Dr. Xiao?" Bu Mo asked frowned.

"Hasn't I proved my ability to you? You should believe in the future I see." When he said this, Liu Ye's heart was floating and he felt a slight sense of fear.

"The future will change, do you know the butterfly effect?" Bu Mo used the access control card to open the last metal door and walked into the laboratory.

Liu Ye stopped talking, but the fear in his heart became stronger and stronger. There is no doubt that Lin Dan is the butterfly wing. No one knows what kind of changes she will bring to the world. Except for her, everyone, everything is still what Liu Ye remembers, so as long as she does not exist, everything will be back on track.

Thinking of this, Liu Ye's eyes burst out with a strong murderous intent, and he covered it up the moment he saw Ma Ze, "Dr. Ma, have you made any progress today?" she asked gently and politely.

Ma Ze hasn't slept for many days, and his eyes are covered with thick black and blue. He grabbed his messy hair and shook his head and said, "The experiment failed again. No, I can't find the password to successfully unlock the gene lock!"

Liu Ye tried to recall for a moment and said, "Maybe you should change your direction and try the mutation and cultivation of super bacteria?" She didn't know bacteriology. Everything she knew was just a few words from other people, and she couldn't even understand the specific meaning. But she knew that this was the key link in the development of vaccines.

"Super bacteria? That is Dr. Xiao's main focus. I am studying the relationship between bacteria and ecology." Ma Ze shook his head dejectedly: "I also know that the only one that can defeat the zombie virus is probably the only super bacteria. I am also ready to go in this direction. However, the relevant research data and research results are all in the hands of Dr. Xiao, and I can't find any way."

Liu Ye stared at him and asked, "You mean, you don't know anything about super bacteria?"

"That's not. After all, I'm a bacteriology student and I know more or less, but I'm not a specialist in this." After several rounds of hard work and several rounds of crushing defeats, Ma Ze no longer dared to be arrogant.

Liu Ye slowly walked to the test bench and looked at a completely destroyed petri dish. She couldn't help but hold her forehead. She adjusted her mood and continued, "Do you still have a project called biochemical armor?" If she remembered correctly, Ma Ze of the previous life once said that in the early years of the end of the world, he began to research biochemical armor, but due to various technical difficulties, it was not until ten years of the end of the world that he successfully developed it.

Since the vaccine is still invisible, she simply concentrates resources to develop biological armor. The effect of that thing is much stronger than that of the vaccine.

Ma Ze held the glasses frame and shook his head and said, "Who did you hear this? I don't have such a project on hand."
