"Mating is the behavior of humans, carbon-based organisms to reproduce the next generation, because it is dioecious, it needs to exchange life force through guò this behavior, which is the most primitive and direct way of exchange, and only through guò this method can you continue to use my life force in this state."

Yulia explained in a serious way, completely unaware that all the human reincarnated lichs, including Ferror, the Ian, also stared at each other in embarrassment.

On the contrary, Zhang Qifan didn't feel anything, just frowned, and said: "Impossible, the exchange of mating vitality will give birth to the next generation, and it will not be able to restore my spiritual power." ”

"The primitive instinct exchange, of course, will give birth to the next generation, but the controlled life force exchange will not." Yulia said.

"Oh?!" Zhang Qifan perked up: "How to do it?" "Mental power is so important to him right now.

"My body is based on the human woman, with a human female function, as long as you pass the act of gò mating, inject your life force into me, combine my life force, and then guide it back into your body." Yulia described it in detail.

Whether it is Zhang Qifan or Yulia, the tone is serious, and the expression is also strict, as if they are discussing the most rigorous academic issues.

But the content of the words made many people blush and their hearts beat faster when they heard it. In the end, Li Lixin couldn't help it, stomped her feet and said, "Can't you go back to the room to discuss this kind of issue?" ”

Zhang Qifan glanced at Li Lixin inexplicably and did not speak.

Yulia looked at her unexpectedly. Curious asked, "Are you shy?" ”

Li Lixin said angrily: "Shy? I have nothing to be shy of, you should be shy. Can't you whisper something so private? ”

"Privacy?" Yulia asked, puzzled, "Why is mating a matter of privacy?" ”

As a tree man. Yulia obviously couldn't understand Li Lixin's statement: "Mating is the act of reproduction, inheritance and evolution of a species, the greatest and most important behavior of a species, why is it privacy?" ”

"If it's privacy, how do you choose the best spouse? How do you pass on the best genes? ”

Yulia's words made everyone dumbfounded. She made so much sense that everyone was speechless.

But these words were indescribably awkward to the ears of those human beings. Shouldn't mating be very private? Is it appropriate to talk about such a thing in full view?

"Maybe." Zhang Qifan didn't know what to think of, and said: "Only humans will regard mating as a kind of entertainment, and it will be carried out even when it is not in heat." This is indeed something that should be put to shame. ”

"Entertainment?" Yuria's eyes widened, and her face was full of incredulity: "Such a life-consuming behavior is regarded as entertainment? ”

When Yulia confirmed that humans were not in heat, they would also mate, and would use a plastic sleeve to block all the life essences. Throw it in the trash.

There are even monosexuals that can be used alone with guò hands or props. The act of unilaterally completing the mating process by simply stimulating the organs.

After hearing this, Yulia's eyes completely changed when she looked at the humans present, and that look was mixed with shock, shock, regret, incomprehension, and so on, which made all the humans present very ashamed.

"This is the essence of life. You're just wasting it? For entertainment or a brief pleasure? I finally understand why you humans have such a short lifespan. Yulia said in an unbelievable tone.

"Ahem, ahem......" Antonio had to interject in embarrassment, "this ......, um." As an authority on the human life sciences, I still have a say in this matter. ”

"In the history of medicine, there have been many cases in which there is no mating behavior due to special reasons such as physical, physiological, and even the cultivation of Tongzigong, and statistics show that there is no direct relationship between mating behavior and individual lifespan."

Yulia glanced at Antonio, shook her head and said, "That's because your human medical technology has not yet reached the point where you need to consume life essence. ”

Antonio was shocked and subconsciously stood up from his seat.

Others may not understand the consciousness of Yuria's words, but Antonio understands that Yulia means that "human medical technology is so poor that it has already hung up before it reaches the point where it needs to consume raw essence".

This sentence was like a lightning bolt piercing through the darkness, instantly illuminating the answers to many of the questions that Antonio had been searching for.

For example, why information adjutants with high mental power generally live longer than ordinary people. For example, why do people still die when they are in good health?

If you explain it with life force according to Yulia, all the questions will be answered, and the life force of these people will be exhausted.

Humans have not been able to find a link between vitality and longevity because of poor medical technology. Life science and technology have only been developed in the last few hundred years, and they are far from being able to accumulate enough cases to prove that life science exists.

Everyone looked at each other, all shocked by Yulia's statement, and finally Huang Chunjiang asked: "Ms. Yulia, in this way, doesn't it mean that after the medical treatment of human beings reaches a certain level, the medical treatment of human beings will be handed over... The less an individual mates, the longer the lifespan? ”

"For an individual, that's true." Yulia nodded affirmatively: "But as a race, improving the quantity and quality is a good way to enhance the strength of the race." Reproduction is the most straightforward way to enhance numbers. ”

Everyone looked at each other, and suddenly it was cold again. Most of the people present were human reincarnated lichs, and they still maintained their morals and outlook on life, and they were really not used to talking about 'mating' and 'reproduction' in public, although they understood that Yulia's attitude was very strict.

Zhang Qifan didn't care about the mood of these human beings, and beckoned to Yulia: "Help me recover." ”

At the same time, Zhang Qifan's heart moved.

The liquid combat suit was poured off his body, stretching into an ultra-thin and ultra-thin silver film, enclosing a large circle around his location.

Yulia walked towards Zhang Qifan, and as she walked, the green vine-like green 'clothes' on her body slowly faded, revealing her tall, white, plump, and flawless carcass.

The liquid screen cracked open, and Yulia walked in, the screen slowly closing.

At the moment when it was finally completely closed, many people who stretched out their necks saw that Yulia slowly sat in Zhang Qifan's arms, and the two naked bodies slowly merged into one.
