Even if the disinfection and cleaning work is done well, there is still a complex and unpleasant smell in the Life Genetics Laboratory.

Entering a closed and separate laboratory, Ye Zhongming saw a lot of blood and dead bodies. If no one knew it, he thought it was a slaughterhouse.

The white test suit that Liu Zhenghong was wearing at the moment was already full of red liquid, and sometimes a small piece of cell tissue was stuck, but she didn't care. She continued to work in the hand. Only when Ye Zhongming came in, she looked up through the isolation glass. Can immediately enter the working state.

It wasn't until forty minutes later that she straightened up, took off the mask and gloves, and passed the isolation area while taking off these dirty clothes.

"Wait for a long time, let's go, go home." Liu Zhenghong put an arm around Ye Zhongming's neck, a serious look, but fortunately just bullying the Genting boss habitually, and immediately let go.

The two went out of the Life Genetics Laboratory, and the guards retreated, but did not keep up.

"How is the progress?" Ye Zhongming instinctively looked around and then asked.

The joke on Liu Zhenghong's face disappeared, but it was replaced by the rigor and seriousness of a top scientific researcher.

"not bad."

This answer surprised Ye Zhongming.

No one knows the pride of Liu Zhenghong and Le Dayuan better than Ye Zhongming, and at the same time, no one knows their prudence in this profession better than him.

Normally, unless it is a successful experiment, Liu Zhenghong will give a positive answer. For the rest, the most common sentence she says is to see the situation.

Now, what she said is very good, which made Ye Zhongming look forward to it.

"This rat king is very open-minded, and the supply of experimental subjects is always sufficient, as if his men are endless."

Liu Zhenghong sneered in the corner of his mouth, even if this situation created good external conditions for her, but she still sneered at the cruelty of this inhuman life.

"This makes me a lot more convenient. Many processes can be carried out together, and many kinds can be tested together."

Liu Zhenghong said while walking: "The requirements of rat kings are not high, there is no specificity, as long as the genes of their next generation are better, I don’t know how long you want to control these guys, but from me, even the technology Temporary non-renewal is enough to allow them to breed more than ten times, and the next pups have significantly improved."

This man-made red clearly understands Ye Zhongming's thoughts. For this group of mutant mice, Ye Zhongming will not treat them with sincerity, they use each other, but Ye Zhongming has the initiative.

"It doesn't need to be significantly improved to let the rat king feel it." Ye Zhongming waved his hand at a place, and Xia Bai's figure disappeared. "How long are their breeding periods?"

"It depends on the variety. During their evolution, they have gone to two extremes in this respect." Liu Zhenghong looked a little dignified.

It’s not surprising that she never put these mice in her eyes before. Her experimental body is a collection of human and beast genes like Dr. He, which is an eighth-level top mutation like Yan Wangshu and Yangos. Plants, how can they be regarded as these underground dirty things.

But when she studied these mutant mice in depth, she was shocked by some data, which led to this dinner with Ye Zhongming.

"The breeding period of some species has become shorter." Liu Zhenghong doubled into the pocket of the white coat, and his voice floated in the end of the night. "In the past, the small house mouse was basically born to be able to reproduce forty days. It will not exceed ninety days, but some breeds now can enter the breeding period in twenty days."

"Twenty days?" Ye Zhongming frowned. This time was too short. "It breeds seventeen or eight times a year, which is too scary."

Hearing Ye Zhongming's words, Liu Zhenghong rolled his eyes, "A very smart person, why are you so stupid now?"

Ye Zhongming was stunned, and then smiled embarrassedly: "Yes, this is different from pregnancy."

"The gestation period of ordinary mice is between 20 days and 22 days, and these breeds only have a gestation period of 10 days, and then they can become pregnant again after a few days. That is to say, after these mice mature, basically half Moon nest, twenty-four nests a year."

Ye Zhongming didn't say anything, because twenty-four nests a year was more terrifying.

"Of course, most of these breeds have obvious shortcomings of one kind or another. They belong to a race that is not powerful, and it belongs to the weak in the rat race."

"Others, the breeding period grows, these varieties are different, but the average maturity period is about two months, and the pregnancy period is also forty or fifty days. The stronger the individual, the longer the breeding period."

Two months plus forty or fifty days... Ye Zhongming thought about it. One hundred days seemed not short, but it was too fast for breeding. He found that he had some errors in the estimation of the total number of these mice. Under the rat king, the total number of mutant mice should exceed their own estimates.

"There is one more thing to remember." Liu Zhenghong and Ye Zhongming turned around a house and saw the bright light shining through the villa where she lived, and the former's face showed obvious warmth.

"The number of births." Liu Zhenghong said briefly: "In the past, there was a saying in the folks, called one male and one mother, two hundred and five years a year, that a pair of mice can breed two hundred and fifty small mice a year, about eight times. "

"Naturally it's not allowed now, but..." Liu Zhenghong paused, emphasizing: "I'm talking about being able to pose a powerful threat to evolutionaries at the same level, from conception to the birth of a newborn rat. These breeds are about a year away. Three nests can be born."

"As for the number of each litter...the number of first births will be less, about three to five, and then increase in sequence, about two more per birth, the peak when it reaches 20, and then the number of each birth It will decline until it is unable to bear children. This process must last fifteen or six times."

Ye Zhongming calculated, according to Liu Zhenghong, this kind of powerful mutant rat has three births a year, and the number of litters in the first year is about 18, 36 in the second year, and 5 in the third year. About fourteen... Now, it is the third year of the last days!

"You mean..." Ye Zhongming stopped, "Now these mutant mice have entered the breeding season!?"

Liu Zhenghong nodded: "Maybe there will be deviations in time. After all, they also need a development period at the beginning of the end time, and many new varieties appear later in time. But there is no doubt that these mutant mice Powerful species have entered or are about to enter their breeding peak!"
