"My pet beast needs a demonic spirit core to evolve. This thing is only available in the Valley of Hell."

"There are actually pet beasts that require demon spirit energy cores to evolve..." Liu Xingyue wanted to ask what kind of pet beast it was, but since Chen Wan didn't take the initiative to say it, it must be that he didn't want to tell himself.

Then he said: "It is true that the demon spirit core is only found in the Hell Valley, but you must also know how dangerous the Hell Valley is. The mysterious gas inside can directly turn people into zombies."

"Besides, this gas can directly penetrate objects and penetrate the skin. Currently, there is no material that can block such objects in Xuan Beast Continent."

Chen Wandao: "That's why I came to you. I know that you must have a solution."

"This..." Liu Xingyue scratched her head in embarrassment and was stunned for a moment without saying a word.

Seeing Chen Wan's expectant eyes and finding it hard to refuse, he gritted his teeth and said, "I do have a solution. It's a protective suit I developed. However, there is still one material missing to completely complete it. In order to collect this material, I have stalled this project.

A year and a half."

"What material? Is it difficult to collect?"

"Ancient purification secret material."

Chen Wan nodded, "I've heard of it, but I haven't really paid attention to how to get it. Maybe I can help."

"...Why don't I show you the protective clothing I researched first, otherwise I will be talking without proof."

Then, Liu Xingyue pressed some switch, and the ground in front of the two of them was instantly pulled away.

A passage appeared in front of the two of them.

"Do you still have a secret room in your home?" Chen Wan said with a smile.

"What you see in the institute is not very important. What is stored here is my hard work."

"Aren't you afraid of telling me such an important thing?"

"My life is all given by you, there is nothing else I can't tell you." Liu Xingyue led Chen Wan to the door of the underground secret room.

Chen Wan also felt that this was indeed the case. If she had helped Liu Xingyue so much and she was hiding it from him, it would really not make sense.

"Come on, come in."

This secret room is much brighter than the secret room in the institute, and the air environment is very fresh.

This smell is the same as Liu Xingyue's body fragrance, but there is no such smell in Liu Xingyue's room.

It proves that she usually spends much longer time in this secret room than at home.

Compared with the research institute, the environment here is much warmer.

The surrounding walls are painted white, making them look clean and tidy.

The floor is covered with soft carpets, which feel very comfortable when you step on them.

There is a wooden table in the center of the room, which is filled with various experimental equipment and documents.

There is a white lab coat placed on the chair next to the table, which looks like what Liu Xingyue usually wears.

There is a single bed in the corner of the room, covered with clean sheets and pillows.

There is a photo of Liu Xingyue when she was a child hanging on the wall next to the bed. It is so cute and beautiful that it makes people want to smile.

On the other side is a blackboard hanging on the wall, filled with various experimental notes and equations.

The whole room is full of Liu Xingyue's life style, making people feel very warm.

Even in this confined space, there is no dull feeling at all.

Compared to the secret rooms of the institute, the environment here is more comfortable and livable.

Liu Xingyue took out a set of black clothes. This is the protective suit.

Protective clothing is like a close-fitting shirt and underpants, not worn outside.

And it seems to cover the whole body, including the head, without any gaps.

"Will it be uncomfortable to wear this thing?" Chen Wan said.

Liu Xingyue smiled confidently, "Of course not, otherwise what would I do for food?"

Chen Wan took it over and looked at it. It was completely black. Only when you look carefully can you see that it is not ordinary black.

Its surface has a slight luster, as if covered with a thin film.

This special coating can effectively block external pollutants, making the wearer safer in high-risk environments.

The design of protective clothing is also very user-friendly.

As Chen Wan watched, Liu Xingyue explained at the side: "It adopts a close-fitting cut to closely follow the curves of the body, allowing the wearer to move freely without affecting the protective effect."

"At the same time, its cuffs and trouser legs adopt a tight sealing design to prevent the penetration of external pollutants."

"The fabric of protective clothing is also very special."

"It uses high-tech fiber materials and has multiple functions such as waterproof, anti-static, radiation protection, and chemical resistance."

"This material not only has strong tensile strength, but can also withstand the test of extreme environments such as high temperature and low temperature."

"In addition to the above features, protective clothing also has a very important feature, which is the issue you are most concerned about. Its breathability is very good."

"Although it is a sealed garment, its internal ventilation system allows the wearer to breathe smoothly without feeling stuffy or uncomfortable even after wearing it for a long time. At the same time, this material has 9%

The probability of nineteen filters out the mysterious poisonous gas."

Chen Wan was slightly startled when he heard this sentence, "Ninety-nine percent? What do you mean?"

"This protective suit already has the ability to resist poisonous gas, but I can't guarantee that the success rate will be 100%. But if I get the ancient purification secret material, I can guarantee that the success rate will be 100%."

Then he said: "In order to develop this protective suit, ten of my team members and I risked our lives to go to the Valley of Hell to understand and collect the information inside."

"We put on the special protective clothing at that time and brought all the necessary equipment and weapons."

"There were countless difficulties along the way. The poisonous air made it almost impossible for us to breathe, and the terrain was dangerous, and traps and monsters might appear at any time."

"We didn't give up, we stayed vigilant and looked after each other."

"Because, in this place full of death, only teamwork can allow us to survive."

"The strange beasts inside are considered ferocious to ordinary people."

"But alien beasts are really not life-threatening to us. The real danger is the colorless and odorless poisonous gas."

"When we were obtaining information about the surrounding plants, a strong poisonous gas suddenly gushes out from the ground and enveloped us all. Our protective clothing and equipment were unable to withstand this poisonous gas, and we could only watch as our bodies began to

Rotting, all nine of them turned into zombies and were killed."

Chen Wan asked doubtfully: "What about you?"

"I developed the serum within 48 hours when I was infected, but the dose was only enough for me." Liu Xingyue laughed at herself with tears in her eyes, "Do you think I'm cold-blooded now...

…”

"How could it be possible," Chen Wan said: "Respect your own life, don't give up on yourself easily, and can develop the serum within forty-eight hours. I have nothing but admiration for you."

Liu Xingyue was stunned after hearing this. She didn't expect Chen Wan to say that.

"It's just that I don't understand why you don't announce the serum to the public? You also know that there are zero antidotes to poisonous gas on the market now, and you can earn a lot of money if you announce it."
