Time flies, time flies.

Konoha 32 years.

It's just the beginning of summer, and the climate is relatively warm, but not too hot.

This day is a special day –

The day of the return of the heroes!

Of course, the war did not end completely.

The heroes who have returned are only seriously wounded on the front line, and they can no longer survive as ninjas in the future.

On the battlefield, they have become a burden to their colleagues, and they must be escorted back to Konoha from the front line, and they can only spend the rest of their lives in the village.

Returning with a large number of wounded were the corpses of the fallen ninjas, who had been buried forever on the earth.

So, on this day when the climate is pleasant, some people are silent, some people are crying, and they may have tears in their eyes, but they are by no means tears of joy.

Despite the absence of any orders, the Konoha folk and the ninja clan had already organized their own solemn ceremonies to welcome the return of the heroes.

But the adults who were waiting for the return of the heroes remained mournful and silent, and the children, who had been lively and active, did not know what was going on, did not dare to speak indiscriminately, but stood silently in a mournful atmosphere.

War is never a good thing.

- Shiraishi's house.

Shiraishi didn't have much interest in greeting those so-called heroes.

He has no relatives to participate in this war, so it is dispensable to greet heroes.

However, Shiraishi knew that Ruri would come over to greet her, and as a member of the Uchiha clan, she had an obligation to greet the people who had returned from a war abroad.

If it's just Ruri, Shiraishi thinks that he should meet Ruri and greet him at the entrance of the village.

But there must be a lot of Uchiha people around Ruri, and if they follow along, they always feel out of place.

For this reason, Shiraishi felt that he should stay in his own home, after all, he still had a lot of experiments to do.

It's been two years, and Shiraishi has not only taught himself the various medical ninjutsu scrolls in the medical ninjutsu scroll that Ruri handed him over, but also mastered them thoroughly.

To put it bluntly, Shiraishi is very confident in his medical ninjutsu skills.

Other than that, the rest of his growth has not been left behind.

According to Ruri's assessment, he now has the strength equivalent to the middle ninja level.

Liuli went through the strict selection of the upper ninja of the clan a year ago, and has the strength of the middle ninja level, and the white stone can be opened with Liuli four or six or five or five, which is naturally the strength level of the middle ninja level.

However, he never exposed his true strength, and in the eyes of others, he was still an ordinary student of a ninja school.

It belongs to the kind of existence that is extremely inconspicuous in the crowd.

Ninjutsu has also mastered a lot, regardless of the three-body technique, palm immortal technique, healing technique, hemostasis, chakra scalpel, these are all the necessary medical ninjutsu for an excellent medical ninja.

As long as you understand the essence of it, it is not difficult for Shiraishi to learn it.

What's more, he has a mature soul, far surpassing ordinary people in terms of self-control, and the time invested in cultivation is about several times more than that of ordinary people.

In addition to the normal rest and classes, the rest of the time is basically spent in cultivation.

It is also through a lot of hardships that we have the current results.

In the cubicles of the house, this is the miniature laboratory that Shiraishi has specially distinguished.

On the table were many distillation flasks, test tubes, utensils, and a Bunsen burner with a flickering red and blue flame.

There are also glass bottles containing a transparent solution containing some rare plant specimens, as well as some specimens of animal torsos, such as eyeballs, livers and other vital organs.

Shiraishi skillfully holds these utensils and blends them in the hope of achieving the results he needs.

The data is then recorded on a computer.

Speaking of which, Shiraishi felt quite surprised, but he didn't expect that the ninja world, which was not very developed in industry, already had a computer.

Although the computer processing system of the current era of the ninja world has not yet reached a very high level in Shiraishi's opinion, it is better than nothing.

He is only good at chemistry, biology, pharmacology, etc., and although he also has an understanding of mechatronics, he is not proficient in it.

Shiraishi can't do such a thing as self-produced computers, and professional things can only be handled by professional people.

And this computer, which has a very low level of processing system in Shiraishi's opinion, also costs Shiraishi a lot of money.

Scientific research is like a bottomless pit, and in the past two years, it has continued to devour Shiraishi's already small assets.

By now, Shiraishi's funding has bottomed out, so it is natural that his research progress will slow down.

He can collect raw materials by himself, but some sophisticated equipment and some more precious materials still have to invest money to obtain.

Just as Shiraishi was agonizing about this, there was a sudden knock on the door.

Shiraishi put down his work and went to open the door.

Sure enough, it's glass.

She is already eight years old, a little taller than she was two years ago, and although she is still childish, her eyes are sharper and colder, giving people a feeling of impersonalness.

Although it's a little ugly, Ruri is indeed a person who doesn't fit very well.

She doesn't know how to accommodate others, and she doesn't know how to deal with interpersonal relationships, but she is very keen on getting stronger.

Therefore, she is a hot-blooded and warlike person at heart.

This may have something to do with the traditional personality of the Uchiha clan, who are usually hot-blooded and warlike.

Shiraishi believes that if it weren't for her true strength to make her look at her differently, it would be difficult to even say a word.

It is precisely because both of them know a little about each other's secrets that Shiraishi thinks that he and Ruri are a good match.

"Is the welcome so soon over?"

Shiraishi introduced Ruri into the room and asked out of curiosity.

According to Shiraishi's estimates, Ruri should spend a day cleaning up the dust for the heroes who have returned from the Uchiha clan.

"No, I just left early, but many people in the clan have died, and some people can't live as ninjas anymore."

Ruri's mood seemed to be a little low.

"It's war, after all."

Shiraishi sighed.

It is undoubtedly normal to die or be maimed in war.

"Why didn't you go?"

Ruri asked Shiraishi this question.

"I have no relatives who have returned from this war."

Only then did Ruri remember that Shiraishi's parents had died in the mission a long time ago.

"I'm sorry."

"It's okay, I don't care about this kind of thing, a person is just a little freer."

Shiraishi smiled at Ruri, indicating that he didn't care, and walked towards the cubicle in the house.

Ruri also followed Shiraishi into the compartment, Shiraishi's private research room.

Shiraishi didn't hide this kind of thing from Ruri.

After all, what she did was not an unseen and forbidden experiment, even if Liuli knew, she would not talk nonsense.

This tacit understanding has been cultivated in two years.

Although it has not yet reached the highest level of 'you don't say it, I already understand', Liuli is not a person who likes to get to the bottom of things.

It's like she knows Shiraishi's true strength, but she never had the idea of revealing Shiraishi.

Shiraishi won't ask Ruri why he didn't expose him, and Ruri won't ask Shiraishi why he hides his strength.

Even so, it doesn't affect the pure friendship between them.

This is the best tacit understanding.
