The teacher still hasn't returned.

This made Amamiya Kenichi a little disappointed, and he was still counting on eating two fish, and then getting some research funds from the teacher or something, after all, these research funds are naturally as much as possible, otherwise they will not be able to do experiments soon.

"But counting the days, it's almost time to hand over to Konoha, and I don't know what the situation of the Uchiha clan in Konoha is after this time after the incident of stopping the water and taking the lead in escaping?" Kenichi Amamiya could only lock up Summer Star in his cell's cell in his laboratory first.

It's just that after glancing at the calendar, Amamiya Kenichi saw the date he marked, and it was about time to go and Konoha to collect experimental consumables, and Amamiya Kenichi would be able to continue his own experimental demonstration at that time, and if the argument was successful, he could start to implement his plan to give Obito a big gift.

Before leaving the laboratory, Amamiya Kenichi also went to see the planting of his rice improvement team, and the rice was basically ripe, and the heavy ears of wheat were full of full grains.

But when Amamiya Kenichi passed, he found that there were two shadow clones of himself who were mysteriously doing something behind his back, and the corners of Amamiya Kenichi's mouth twitched, but he still planned to go over and see what they were doing.

"Not for now, ontology." A shadow clone stopped Kenichi Amamiya, and Ken glanced at his shadow clone, good guy, the scorpion hasn't made an AI crisis yet, but you gave me a shadow clone crisis first, right?

"Those two guys think it's too boring to look at plants every day, so they're studying hydrofluoric acid over there, and they're making hydrofluoric acid right now." The shadow clone explained, and Kenichi Amamiya immediately stopped.

Damn, if it weren't for the fact that these two shadow clones had been doing research before, Amamiya Kenichi would definitely wonder if the shadow clones were planning to do something to change their identities?

Hydrofluoric acid? Doesn't this stuff have to be made in a heavily guarded chemistry lab? And the requirements are very high, a full set of protective clothing and gas masks and so on can be prepared, and it is also required to be in a place with a good ventilation environment.

The ventilation of this place is indeed good, but the problem is that his shadow clones are not wearing protective clothing or masks.

But soon Amamiya Kenichi remembered that these were his own shadow clones, which were themselves composed of chakra, and hydrofluoric acid, a highly toxic substance, was for the shadow clones, at most, they would be injured and dissolved, but the injuries would not be transmitted back to their bodies.

That's why these guys are so arrogant, so arrogant, and even dare to prepare hydrofluoric acid in this kind of place.

Hydrofluoric acid, this thing can know what this thing is from the name, an acid, and even very funny is that this thing is classified as a weak acid, which is not as strong as sulfuric acid, but if it comes to lethality, then sulfuric acid is really not qualified to lift shoes for hydrofluoric acid.

Hydrofluoric acid is extremely corrosive, what corrosion encounters, except for some special materials such as polyethylene or some special metals, otherwise many things can be corroded, and glass cannot be used to install hydrofluoric acid in the laboratory.

Because glass can also corrode.

But the reason why this thing is classified as highly toxic is because this thing is very volatile, and it is very harmful to the human body, a drop of hydrofluoric acid drops on the skin, if it is not treated with something like special defluorin, then it is easy to cause the bones to be burned through.

If you are sprinkled with hydrofluoric acid, then this treatment is also very difficult.

Therefore, in the previous life, the preparation, transportation and preservation of hydrofluoric acid were very demanding tasks, and special antidotes had to be prepared.

"What are they doing with this?" Amamiya Kenichi didn't understand a little, and even he himself changed to a position upwind, the volatility of hydrofluoric acid is very strong, although the taste is also very pungent, but it is better to stay away.

"I'm idle, there's nothing to do, and aren't you planning to develop some new ninjutsu on the main body? What do you think of hydrofluoric acid? The shadow clone looked excited, and Kenichi Amamiya took a deep breath, well, he admitted that it was his own problem.

He didn't expect his shadow clone to be so outrageous, but the harm of hydrofluoric acid to the human body is indeed great, and if it is used with ninjutsu, then the effect is naturally very good.

For example, if you combine hydrofluoric acid with fog concealment to create a dense fog area containing a large amount of hydrofluoric acid, the enemies who come in will only be wary of sneak attacks, but they will not know that this dense fog itself is a means of attack.

"But according to this statement, wouldn't it be possible to develop a Fire Escape White Phosphorus Flame Bomb?" Kenichi Amamiya came with some inspiration.

That's too good.

The White Phosphorus Bomb is a weapon that is easy to make, there is no technical difficulty, and the most important thing is that this thing is simply an alternative version of Amaterasu, once the White Phosphorus Bomb starts to burn, it will continue to burn until it is clean.

Therefore, if this thing falls on human skin, it will burn the skin, burn the flesh and burn the bones, and the white phosphorus combustion will also release toxic chemical fumes, so it is still a very dangerous and practical weapon.

In the previous life, the psychological shadow caused by this thing was very large, and it was too cruel, and it was once forbidden to use it.

"But in that case, those weapons that were forbidden in the previous life should be considered to be extremely useful in the Hokage's world" Amamiya Kenichi expanded his mind, he felt that this was really feasible.

After all, there are no such strange conventions in the ninja world.

"Develop well, pay attention to safety, and don't affect crops." Amamiya Kenichi patted his shadow clone, this time it was a surprise, he really didn't expect his shadow clone to have this kind of operation.

Kenichi Amamiya had known about hydrofluoric acid before, but because this thing was too threatening, Kenichi Amamiya didn't try to prepare it, and he forgot about it when he got to the ninja world.

But now, it's good to make it, and when the time comes, just put it in a glass bottle and throw it down.

Although the glass bottle will be corroded by hydrofluoric acid, before the corrosion wears through, the glass bottle will fall to the ground, which can directly cause damage to the enemy, and it is not so easy to detect, and the concealment and lethality are very high.

The only problem is that after the hydrofluoric acid is made, it needs to be experimented to see if the hydrofluoric acid will be affected by the chakra.
