After running, Zhizhen was ready to go to work.

He returned to Konoha Hospital and came to the research class. At this time, quite a few people have already come.

Zhizhen greeted each other with a smile, and then couldn't wait to observe the row of glassware on the table.

This week, in addition to normal cultivation, Zhizhen also conducted in-depth research on the Healing Light Worm and the Rock Hard Worm.

First of all, he observed the specific reproduction process of the rock hard worm, which is asexual reproduction, that is, monomeric reproduction, and there is no sex difference.

By stimulating their bodies through chakra, their bodies that were originally difficult to be injured by swords will crack, and over time, new juvenile rock worms crawl out of their bodies, which are three times smaller than adult rock worms.

And the number of rock hard worms that are born is mostly two, and with individual differences, sometimes three will crawl out.

If chakra cultivation is not used, under normal circumstances, the rock worm will not start to reproduce until the day it dies.

The dead worms will be devoured by the newly-born worms as food to replenish their nutrients.

However, the vitality of this insect is very tenacious, and Shizhen separates the two newborn rock hard worms, and one of them does not give it food.

The one that didn't eat anything, didn't receive the chakra, still lived for a week.

And today is exactly a week, this one died, but the size did not change, and when it died, no new rock worms were born. In terms of hardness, it is not as good as the one that received nutrients.

As for the one that received the nutrients, it was already like an adult rock worm on the third day, and when it died, it also gave birth to a new rock worm.

At this point, Zhizhen probably understood the survival nature and requirements of rock hard insects.

At the same time, he also put the rock hard worm and the healer worm together to see if the two would mate and give birth to new bugs.

But Zhizhen obviously thinks too much about this, because rock worms reproduce asexually, there is no sex difference, and therefore there are no reproductive organs.

Copulation or something is impossible.

As for the healing light worm, this worm is sexually reproduced and oviparous. After mating, the female will release eggs, about 10 at a time, and they can grow within a day.

The rate of reproduction is faster than that of rock hard worms. The life cycle is also longer than that of rock hard worms, about fifteen days.

If he doesn't mate, Zhizhen can also use chakra to breed, using the secret technique of the oil girl's insect cocoon, which accelerates the egg-laying and larval growth of the healing insects.

But in this way, it is consuming the life force of the insect, and the original fifteen-day life cycle will be shortened by nearly half after being stimulated with chakra, but the effect is not reduced.

In terms of level, the healing insect is indeed above the rock hard insect, and the healing insect is also very powerful in terms of effect, but the only difference is that the attack power is poor.

In addition to understanding the survival conditions of the two insects, Zhizhen also made practical research on the two insects.

A very interesting phenomenon was discovered.

That is, although the light worm lacks attack power, it has a strong resistance to poison, no matter what kind of poison, the light worm will devour it.

Zhizhen injected a small stream of poison gas into the Healer's vessel, and in less than five seconds, the purple poison was absorbed by the Healer, and there was nothing wrong with it.

For corrosive venom, as long as the body does not come into contact, the healer insect can even drink the venom, and its resistance to poison can be said to be very outstanding.

In this way, Zhizhen is not afraid of being poisoned, because this insect can be regarded as the natural enemy of almost any poison.

However, its shortcomings are also obvious, the body is fragile, and it can be easily destroyed with a cotton swab.

The resistance of the rock hard insect to poison is very poor, a small breath of poisonous gas can make the rock hard insect unconscious, and the corrosive venom can directly melt the rock hard worm.

But in this case, its resistance to physical attacks, and its resistance to ninjutsu is extremely strong.

It is difficult to burn the dark part of the root with fire, and the general kunai can't even beat it, and although Lei Dun can paralyze the rock hard worm, it will not let the rock hard worm die. With Chishin's chakra treatment, he will also recover very quickly.

Of course, not to mention the powerful Fire Dun and Thunder Dun, the former can directly burn the rock hard worm into ashes, and the latter can directly electrify it into a lump of carbon, and the rock hard worm naturally can't bear it.

But it's normal to have shortcomings, let's not mention the light worm for the time being, figure out the advantages and disadvantages of the rock hard worm, and Zhi Zhenxin also has a general direction for the use of the rock hard worm.

When to use it and how to use it, I also have a pretty good grasp in my mind.

And after a week of research, Zhizhen also had a bold idea, he was wondering if using the immortal chakra to cultivate these two kinds of insects would make these two insects qualitatively change.

Zhizhen is very curious about this and can't wait to try it.

It's a pity that he can't get his hands on natural energy now, so he can only see if he can ask Zilai to help him in the future, or let Naruto, who has learned the immortal mode, do a favor and do a study.

There are many psychic beasts in the Hokage, but there are only three holy places that can learn the immortal mode.

As for these three psychic beasts, Zhizhen estimated that he would not be able to get them.

The toad of Miaomu Mountain will never teach him. The slugs of the Wet Bone Forest, Tsunade probably won't be able to teach him.

As for the snake in the Dragon Cave, if you give the big snake pill enough price, the big snake pill may be able to teach.

But Orochimaru is a person, it's too crazy, and it's almost a magic barrier when he engages in research.

And the snakes in Longdi Cave are not easy to get along with, and Zhizhen has always disliked snakes.

Therefore, this research Zhizhen can only be put on hold for the time being.

"How's your practice?" Just as Shijin was observing, Director Sato's voice rang out.

"Huh?" Zhizhen looked up and saw that it was Sato, so he hurriedly said, "It's okay, Director Sato, do you have anything to do?" ”

"That's fine, but don't put down your research." This week, Sato thought about Zhizhen's words carefully, and felt that what Zhizhen said was not unreasonable, and his attitude eased Zhizhen a lot.

Seeing Sato so gentle, Zhizhen was indescribably surprised, but at the same time he felt more relaxed.

"Yes, Director Sato. I'm not going to fall behind in research. Zhizhen assured.

"Well, what kind of worm is this?" Sato nodded, then looked at the rock worm in the vessel.

"This is the rock worm, my second insect." Zhizhen said truthfully, in the face of Sato, an old-timer, Zhizhen was more respectful, so he patiently explained.

"Oh, what's the property?" Sato asked with interest.

"Well, it's hard."

"Hard?" Sato was puzzled.

"This worm lives on ore from the soil, so its body surface is very hard."

"I see, does it have any effect on medical treatment?"

"I haven't found ...... for the time being."

Hearing this, Sato's originally excited face suddenly stepped down and said, "Let's change the study." And then he left.

He didn't take a few steps, and he said without looking back: "Bugs that can't be used for medical treatment are not good bugs." ”

"......" Zhizhen has nothing to say.

"Ouch, Director Sato didn't scold you, Zhizhen can, you kid is finally sensible." Yuan Ye quietly walked over and quipped.

"It's okay, it's okay, I didn't expect Director Sato to actually support my practice." Zhizhen smiled.

"Then you have to work hard, you know, our medical department is not good at combat effectiveness, and the only one who has some strength is you. What must protect us. Yuan Ye said.

Zhizhen nodded heavily when he heard this, "Definitely!" ”

Yuan Ye was stunned for a moment, then hugged Zhizhen's shoulder hard, and said with a smile: "You guy has really changed, but it's okay like this!" ”

Zhizhen chuckled when he heard this, and Yuan Ye smiled: "You continue to be busy, and I will continue to work." We'll have dinner together. ”

"Good!" Zhizhen responded, and then Yuan Ye left.

Looking at the busy figure of the field, the colleagues of the medical department sincerely said that they must be protected in August.

Even though they were all friends of the original Shizhen, Shizhen didn't want to see any of them die.

"Go for it." Zhizhen secretly cheered up and began to work.
