"I need a mouse..." the old mouse sat in front of the unfinished stone platform and quickly wrote on the stone board: "mouse, I remember this is a very perfect experimental body. It is one of the smallest mammals with strong reproductive capacity. The cycle between generations is very short, so it can try to mutate."

"Mice are very close to humans in biological evolution. Well, they may be the same creatures that appeared 750000 years ago as humans. In addition, the early embryonic development of mice is very close to that of human beings, so the mutation probability of mice is similar to that of human beings. "

"In addition, the structure of tissues and organs, cell function..."

Rat boss excited: "advanced neural activity, gene homology, sequence, transformation maturity, too perfect, just use the mouse, I'm not a rat!"

"Wait a minute. It's not even in the '80s. The technology of gene editing hasn't started at all. What am I thinking?" The old rat grabs his head dejectedly, and his hair is taken off: "if, if my body is still there, my brain is still there..."

His eyes were red with blood, and he sat on the ground for a long time. Suddenly, he regained his spirit: "the magic trick that old hailibu got... Now it seems that he can only rely on that thing."

The old rat unfolded a scroll, in which appeared a thick stack of books made of unknown leather.

He put on his gloves and touched the book: "a book made of insect skin can achieve this level. It seems that there is a bit of magic in it."

Like all people from the future, rat boss didn't pay attention to witchcraft at first.

"I thought the magic was fake, but think about it carefully..." the rat said to himself, "maybe it's the ancient wisdom, the ancestors' exploratory research on the variation of primitive creatures."

He opened the first page of the book, looked at it for a long time, and frowned, "what does that mean?"

From the perspective of Fang Tang, we can see the contents of the book completely.

It's full of traditional Chinese characters.

Moreover, this is a complete inheritance record of witchcraft. At the beginning, it was the explanation of witchcraft in various ancient books.

Fang Tang looks hard.

... "on the origin of various diseases - Gu Du Hou" records as follows: take more insects and snakes, store them in utensils, and let them eat each other. Only one thing alone is called gu!

The meaning of this passage is that the ancients put the insects and snakes in a closed vessel and let them kill each other. The last thing that survived was a powerful poisonous insect.

Keep looking down.

"It's more effective to make poisonous insects than to make them on the day of the Dragon Boat Festival. When their Yang Qi is at its peak, they make medicine, which leads to illness and death. They also use snakes, poisonous insects and centipedes to make them. They can kill animals at one touch. "

"There are thirteen changes in the category of Gu, which are called Gu, snake Gu, jincangu, miepiangu, shitougu, loach Gu, changu, Zhonggu, diangu, yinshegu, shengshegu, sanshigu..."

Rat boss made a mark on the last kind of "three corpse Gu".

Fang Tang also followed the perspective of this information, and together with the rat boss in the virtual light and shadow, studied the three corpse insects!

This poisonous insect was invented by the Wu tribe of Miao Nationality in Yunnan Province. It is known as the most poisonous poisonous insect. The method is to find blue, red and white poisonous insects first. Then put these poisonous insects into the human body, and after the death of that person, feed the poisonous insects with the corpse.

In this way, the first generation of insects will be cultivated, and then the first generation of insects will be put into the human body, and so on, until the third generation of insects appear.

It seems that it is not difficult to see the description. In fact, there is a survival rate problem.

Tricolor poisonous insects are easy to find. The jungle is full of them, but it's too difficult for humans to cultivate them.

In particular, not every corpse can successfully feed the insects.

In the book of wormlike skin, the fastest feeding record also cost 167 living corpses, and this is only the first generation. Most of them can only cultivate the first generation of insects. That's a great achievement.

The second generation as like as two peas, the three generation of worms must be exactly the same.

Fang Tang calculated a little, three generations become two generations, three generations become three generations. That is to raise at least nine blue, nine red and nine white worms.

The data is not complicated, however, considering the success rate. I'm afraid tens of thousands of bodies

At this time, Fang Tang understood the rat's infatuation with mice.

Mouse is very close to human in biological evolution, early embryonic development is also very close to human, tissue and organ structure, cell function, advanced neural activity, gene homology, sequence... These characteristics make the cultured mouse can completely replace human!"What a madman the rat is!"

But also a genius.

If we use mice to cultivate the three corpse insects, we will never worry about the number.

Fang Tang continued to unfold the information recorded by Cain.

Rat boss spent tens of thousands of mice, and finally successfully raised the legendary three corpse insects.

Moreover, in order to maintain the activity of the insect, he also developed a kind of "parasitic rat" which can provide nutrition for the insect.

That's the black mouse Fang Tang saw not long ago, covered with insects.

But rat boss is more than that.

He seems to continue to experiment, trying to cultivate a more advanced four corpse gu!

……

Fang Tang withdrew from Cain's record and could not help shaking his head: "the four corpses are really powerful. It's unprecedented. Rat boss may be the most powerful demagogue in the world, but what's the use of time and space crystal?"

"Snake Girl, I thought he wanted to cultivate mice that can drill holes, but now..." Fang Tang shook his head.

Snake Girl leaned on the platform and said nothing.

Fang Tang felt something was wrong and came here in a hurry.

Snake Girl's whole body was stiff and cold.

Fang Tang tried her pulse and sighed.

He went to the last stone platform, pulled off the dusty cloth and covered the snake girl who was exhausted.

"Sorry, you can't wait for me to solve the puzzle." Fang Tang said softly, Cain laughed in his ear: "according to the information I got, isn't this hide and seek game that the more players die, the better for you?"

Fang Tang said coldly: "this is no longer a game. The rat doesn't want to finish the level at all, while long Yunhai and Liu Wenwen... If they know the truth, I'm afraid they will..."

"Will you choose to stay?"

Fang Tang sat down wearily: "yes, their lives are incomplete and full of regrets. Long Yunhai certainly wants to enter the real world of the 1980s to stop the tragedy of his wife and children. And Wenwen, she wants to change her fate more than anyone else. "

Cain said nothing: "but what about the game? Do you want to go out, too? "

Fang Tang didn't answer this question. After a long time, he said, "I believe in the protection law of the paradox of time and space, so I won't do such boring things."

He got up to leave.

Suddenly he stopped again.

On the last platform, a stone map attracted him.

"This is..."

Cain scanned: "it's like a railway map."

"Yes..." Fang Tang reached out and touched the map: "this is the route map from Xishuangbanna, Yunnan Province, to Kunming, and then to your city."

Cain scanned again: "no, there's a new line on it. Ah, I know!"

"What?" Fang Tang asked in an urgent voice.

"It's the Guiyang Kunming railway. It started in the 1960s and was completed in the 1970s. It's 700 km long. By the 1980s, it had been electrified. Later, it was connected to the Shanghai Kunming Railway... It can enter the magic city!"

The railway line from Xishuangbanna outside the Xiaoshan village to modu?

It's the only way to get to mordu in Yunnan Province in 1980s!

Why does rat want to do this?

Fang Tang looked down from this road map.

On the stone slab, there is also a string of English.

The English is very messy and intermittent. It seems that the rat wrote it by hand.

"System, is it a system? The law of protection runs in a systematic way... In overlapping time and space, from nubai village to modu... There are always loopholes in the complete system. "

Fang Tang's eyes lit up.

Continue to see: "DoS attack, the most crude and direct way, is it feasible?"

Fang Tang's eyes are brighter.

He has figured out a lot of key doubts.

"DoS attack, attack system, four corpses, insects, railway lines... Well, it's a little short. In that case, insects need at least ten groups, and they need at least two navigation points!"

Fang Tang said to himself, Cain had been confused: "what? What are you talking about, old Tang? "

Fang Tang quickly turned around: "I know the complete plan of rat boss, he is not a madman, but a vicious genius!"
