Roulette World

No matter how well the disinfection and cleaning work is done, there is still a complex and unpleasant smell in the life genetic laboratory.

Walking into a closed separate laboratory, Ye Zhongming saw a lot of blood and corpses. If people didn't know it, they would think it was a slaughterhouse.

The white test suit that Liu Zhenghong was wearing at the moment was already covered with red liquid, and occasionally small pieces of cell tissue still stuck to it, but she didn't care at all, and continued with the work in hand, only when Ye Zhongming came in, she raised her head and took a look through the isolation glass, But it was back to work right away.

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

"Wait for a long time, let's go, go home." Liu Zhenghong put his arms around Ye Zhongming's neck, looking unscrupulous, but fortunately he just bullied the boss of Yunding habitually, and let go immediately.

The two left the life genetic laboratory, and the guards retreated wisely, but did not follow.

"How's the progress?" Ye Zhongming instinctively looked around vigilantly, and then asked.

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

"not bad."

Ye Zhongming was surprised by this answer.

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

Usually, Liu Zhenghong would give an affirmative answer unless it was an experiment that was about to succeed. For the rest, what she said most often was that it depends on the situation.

But now, what she said was very good, which made Ye Zhongming look forward to it.

"This Rat King is very aggressive. The supply of experimental subjects has always been sufficient, as if its subordinates are endless."

A sneer appeared on the corner of Liu Zhenghong's mouth. Even though this situation created good external conditions for her, she still sneered at the cruelty of this inhuman life.

"This has made me a lot more convenient. Many processes can be carried out together, and various possibilities can be tested together."

Liu Zhenghong said as he walked: "The rat king's requirements 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 if the technology Without replacement for the time being, it is enough for them to breed more than ten times, and the pups have improved significantly every time."

This person-making star obviously understood Ye Zhongming's thoughts. For this group of mutant mice, Ye Zhongming would not treat them sincerely. They used each other, but Ye Zhongming had the initiative.

"It doesn't need to improve obviously, just let the Shu King feel it." Ye Zhongming waved his hand towards a place, and Xia Bai's figure disappeared, "How long is their breeding period?"

"It depends on the species. In the process of evolution, they have gone to two extremes in this regard." Liu Zhenghong's face was a little dignified.

She has never taken these mice seriously before, which is not surprising. Her experimental body is a collection of human and beast genes like Dr. He, and it is a top-level eighth-level mutant like Yan Wangshu and Yangos. Plants, how could they look at these underground dirty things.

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

"The breeding period of some species has become shorter." Liu Zhenghong put her breasts in the pockets of her white coat, her voice drifting in the apocalyptic night, "In the past, it took forty days for small house mice to be born and reproduce, and for large ones. It will not exceed 90 days, but some varieties can enter the breeding season in 20 days."

"Twenty days?!" Ye Zhongming frowned, this time is too short, "Seventeen or eighteen times a year, this is too scary."

Hearing Ye Zhongming's words, Liu Zhenghong rolled his eyes, "You're quite smart, why are you so stupid now?"

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

"The gestation period of an ordinary mouse is between twenty and twenty-two days,

And these breeds only have a gestation period of ten days, and after a few days of recovery, they can conceive again. That is to say, after these mice mature, they basically litter for half a month, twenty-four litters a year. "

Ye Zhongming didn't speak, because twenty-four litters a year was even more terrifying.

"Of course, most of these breeds have obvious shortcomings of one kind or another. They belong to races that are not strong in combat effectiveness. Among the rat clan, they are weak."

"In addition, the breeding period increases. These varieties are different, but the average maturity period is about two months, and the pregnancy period is also forty to fifty days. It follows the characteristic that the stronger the individual, the longer the breeding period."

Two months plus 40 to 50 days... Ye Zhongming thought for a while, 100 days seems not short, but it is too fast for reproduction, he found that his estimation of the total number of these mice was a bit wrong, Under Shu King's rule, the total number of mutated mice should have exceeded his estimate by a lot.

"Don't forget one more thing." Liu Zhenghong and Ye Zhongming turned around a house and saw a bright light shining from the villa where she lived, and the former showed obvious warmth on his face.

"Number of viviparous births." Liu Zhenghong said simply and succinctly: "In the past, there was a folk saying that one male and one female, two hundred and five a year, said that a pair of mice can breed 250 pups a year, and the frequency is about eight times. "

"Of course it's not allowed now, but..." Liu Zhenghong paused, and emphasized: "I'm talking about the single-body that can pose a strong threat to evolutionaries of the same level. From the time they can be conceived to the birth of newborn rats, these breeds last about a year. Can have three litters."

"As for the number of each litter... the first litter will be less, about three to five, and then increase in order, and each litter will increase by about two, and it will peak when it reaches twenty, and then the number of each litter It will decline until it becomes infertile, and this process will last fifteen or six times.”

Ye Zhongming calculated it in his mind. According to Liu Zhenghong, this kind of powerful mutant mouse gave birth three times a year. The number of litters in the first year was about eighteen, in the second year it was about thirty-six, and in the third year it was five. Around fourteen... Now, it is the third year of the last days!

"You mean..." Ye Zhongming stopped, "Now these mutated mice have entered the peak breeding period!?"

Liu Zhenghong nodded: "There may be a deviation in time. After all, they also need a development period at the beginning of the end of the world, and many new species appear later in time. But there is no doubt that among these mutant mice The powerful species have already entered or are about to enter the peak of their reproduction!"
