"Vaccine people?"

"Yes, the vaccine, of course, is not the same as the vaccine you use, I am the vaccine of this planet."

"You know what vaccines mean!"

"Well, it seems to be a cure. In other words, you are healing the earth? Is an ecologically destroyed earth equivalent to being sick? ”

"It's not a cure, it's a prevention!"

"Prevention?"

"Can you understand the elimination of all existences that are harmful to the ecology of the planet?"

"Erase the Hazards...... Now the earth's ecology has been destroyed by humans, uh...... You're saying you're going to wipe out humanity? ”

After realizing the meaning of Zhang Yue's so-called obliteration, Saitama felt a chill all over his body, and his spirit immediately became highly concentrated, and his vigilance against Zhang Yue instantly increased to an unprecedented level.

"Relax, if I were going to do it, I would have done it a long time ago, why should I ask you, a human being, to do everything with me to protect the ecological environment?"

From his intuition, Saitama vaguely felt that Zhang Yue didn't seem to be lying, and his heart couldn't help but relax, although he didn't completely relax his vigilance, but his face was much better, and then he thought about Zhang Yue's actions, and after thinking that he didn't need to pay much attention to an existence that tried to destroy humanity, he believed even more that Zhang Yue should indeed have no hostility.

In other words, if Zhang Yue knew that Saitama didn't care about himself so much, maybe he would sincerely praise this guy; "You're so humble!"

Subsequently, Zhang Yue explained his thinking to Saitama.

In general, Zhang Yue's idea is that even if human beings are wiped out, it does not mean that they can really protect the earth's ecology, and it may even make the earth's ecology worse, because human beings themselves are also part of the ecology.

During this time, Saitama also asked a very profound question, about the ...... of life

"For the earth, is the ecological environment or life really important? Even if the ecological environment becomes worse, even if all life is extinct, the earth itself should not have any changes, the environment on the earth was so bad that there was even no life, and the earth did not rotate in the same way. ”

In this regard, after expressing surprise in his heart that Saitama could think of this question, Zhang Yue gave a general answer: "The value of life is never as simple as you think, even for the entire universe, life has its own unique meaning." ”

After finishing speaking, when he asked Saitama what the meaning of life was, he replied with an unfathomable face: "Don't say, don't say!" ”

Looking at Saitama's unaware look, Zhang Yue himself was secretly complaining: "What is the meaning of the existence of life?" Hehe, I still want to know about this kind of philosophical question. ”

Through the experience of the three worlds, Zhang Yue can at least determine one point, that is, the existence of life is related to the planet and even the world, for example, whether it is the will of the giant world or the will of the planet encountered by this world, it is closely related to life in the world or on the planet.

As for what the connection is, Zhang Yue can only say that he is only a little vague guess now, and the specific situation is still vague.

However, Zhang Yue believes that with his own improvement in all aspects, one day, he will be able to figure it out, and what he has to do now is to continue to improve himself.

For several days after that, Zhang Yue and Saitama were not idle.

At the same time that Zhang Yue instilled all kinds of environmental protection knowledge in Saitama, he also studied Saitama's body again and again in the name of checking his body every day, saying that Saitama's progress speed is still exaggerated, and the speed of the 'body' attribute is not reduced at all every day, if it were not for the needles and other equipment used by Zhang Yue to be constantly updated into better materials, it is estimated that the sampling work would have been unable to continue.

However, materials cannot be updated forever, and they will always reach the limit of technology.

Finally, after Saitama's 'body' attribute was raised to level 25, Zhang Yue no longer had a needle in his hand that could successfully take blood from Saitama.

It's not that Zhang Yue can't break through Saitama's defenses at this time, but those are some extremely laborious means, and in terms of Zhang Yue's vaccine human body at this time, it is actually a little more than worth the loss.

He already has a certain number of various tissue cells in Saitama, which is enough to study for a long time.

After that, after telling Saitama that he would have another inspection every month and assigning him some tasks, Zhang Yue left temporarily.

After all, Zhang Yue has other things to do, and it is impossible to spend it with Saitama all the time, and every day he watches Saitama improve crazily on the side, seeing that this guy has quickly changed from not his opponent to an existence that is even more awesome than him (the doppelganger), it is really tiring enough, or out of sight and out of mind.

As for Saitama, he sent Zhang Yue out of the door very respectfully.

Because under Zhang Yue's treatment, the hair on this thing's head really grew back, although the hair was very thin, and it all fell out when it grew to about three millimeters, but it really gave him hope.

Zhang Yue's confidence increased greatly, and his mind changed instantly, and he completely regarded ecological protection as a bright way for him to treat his bald head.

Not to mention Saitama, an environmental fighter who had already begun to take the initiative to protest at many polluting factories and distribute leaflets everywhere, Zhang Yue had already returned to H City at this time, and after dealing with many backlogged affairs, he reassigned various tasks to his subordinates, and then began to conduct the most detailed research on various tissue samples on Saitama's body.

There are hundreds of experimental projects every day, which makes Zhang Yue a little busy.

Even the unlicensed knights don't have much energy to pay attention here, and it usually takes several days to pay attention to the situation on the side of the unlicensed knights and Saitama.

And under the sight of Zhang Yue, who only occasionally pays attention, the unlicensed knight has also done everything he can, and he can no longer find a way to improve his test scores in the short term.

So I didn't hesitate to sign up for next month's Pro Hero test.

This is the second time the undocumented knight has taken part in the test, and he believes it must be the last.

"I'm finally going to be a glorious hero, by the way, shouldn't I tell anyone else about it? Forget it, let's wait until after the test. ”

Looking at the registration form in his hand, the unlicensed knight was full of ambition for a while, although he hadn't even done the test yet......
