In the laboratory, under the bleak white light, Hanzo put down the pen in his hand and stretched.

"It's finally done. With these two things, it can be regarded as an explanation for Orochimaru. Hanzo thought to himself as he looked at the two reports on the table.

In order to avoid revealing something ahead of his time because of the memories of his previous life, Hanzo's two reports closely focused on Orochimaru's original direction and were not mixed with anything.

Of course, Hanzo is not Orochimaru after all, although there are also some knowledge of previous lives as support in these aspects mentioned by Orochimaru, but ninjutsu is another thing after all, and the report written by Hanzo is not a mature ninjutsu and technique, but only a feasibility verification of the characteristics of some sounds and development directions.

For example, the explosion sound mentioned by Orochimaru and the piercing sound of the blade slashing are the embodiment of the characteristics of sound frequency, volume, and pitch in Hanzo's view.

So Hanzo pointed out these things in the report and added the corresponding experimental data, of course, some proper nouns Hanzo was deliberately vague.

Hanzo stood up, packed up the report, stored it in the dark compartment designated by Orochimaru, turned off the lights and doors, and prepared to go back to rest and go out to practice again.

Lying on the bed, Hanzo looked at the ceiling with his head resting on his head and hands, and thought habitually.

Although he has been doing Orochimaru's business for this time, it is precisely because of such a long time that Hanzo has completely adapted to the power of the spell seal.

Even though the reality wasn't as Hanzo expected, the one that Hanzo wanted most of was the ability to recover by absorbing the flesh.

Hanzo has tested the state after activating the spell seal, and the only change in his body is that his flesh has become harder and his defense has increased, and as for the three heads, six arms, and wings, these changes are nothing.

"Now for me, the water escape aspect can only be slowly improved through water grinding skills, and it is impossible to improve quickly; Lei Dun can be put on the agenda, as long as that idea is successfully realized; The others can't be left behind, illusions, body arts, and sealing techniques must keep up. Ay! It's a pity that the sealing technique is stuck here, so I can only wait for Orochimaru to come back and ask him......"

Although the mantra seal in Hanzo's heart was a must-have, he never took it very important except for those few abilities. Its effect on Hanzo itself will be in the future, when the amount of Hanzō's chakra accumulates to a very large amount.

The plan was pretty much the same, Hanzo closed his eyes and took a nap in his mind.

……

Walking out of the base, the sun was shining outside, and Hanzo walked from the dim environment to the bright outside, his eyes were difficult to adapt for a while, and he couldn't help but raise his hand to cover it.

"Hey, it's hard to use your eyes in such an environment every day, and you may become nearsighted one day." Hanzo said he was very concerned about his eyesight.

"Hey, by the way, that guy Orochimaru is better than me with his eyes and likes to stay in a dark environment, will he be short-sighted?" Thinking of Orochimaru from his own eyesight, Hanzo thought curiously, "The snake seems to have poor eyesight, and his eyesight is not good with a pair of snake eyes." ”

Arriving at the destination, Hanzo put an end to his thoughts, collected his mind and began to practice.

"Gollum!" The water balloon accumulated on his hand and gradually wrapped the whole hand, but when Hanzo tried to create a vacuum, he couldn't control the form, and he scattered on the ground with a "bang".

"Come again!" A failure is nothing, Hanzo silently cheered himself up in his heart.

The sun was setting little by little, time slipped away inadvertently, and failing again and again made Hanzo no longer in the mood to appreciate this infinitely good sunset.

Hanzo didn't care about the first few failures, and in his mind it was nothing more than not being skilled enough at the beginning. But when he discovers that every failure is in the same place without any improvement, Hanzo realizes that something is wrong with his method.

After that, every time you fail, you summarize it, make assumptions, control the variables, and use the elimination method to find the real factors that affect the success.

"Try it once, this one will definitely work!" Ignoring the whitish right hand that had been blistered, the water element accumulated again.

"Yes, exactly. And then like this...... Good! There was a burst of excitement, and the water balls of the vacuum compartment that had just been condensed dispersed and spilled on the ground.

"It worked." Hanzo thought happily, "Oops, it hurts." ”

Hanzo, who had relaxed, felt the exhaustion of his body and his right hand, which had become stiff due to the accumulation of chakra, "It's getting dark, go back to eat." Rubbing his hands, Hanzo returned to the base with a little starlight.

With the prerequisites settled, Hanzo put Rachel on the agenda. In the following days, Hanzo went out early and returned late every day, and as for the laundry and cooking, he shamelessly handed it over to Junmaro and them. In addition to building a ninja village, poor Jun Maro also has to give Hanzo laundry.

……

On this day, when Hanzo came back from cultivation with his tired body, a figure suddenly came out in front of Hanzo, and the startled Hanzo immediately retreated and took a fighting posture.

The man didn't move, just quietly watching Hanzo's responses one after another.

Hanzo struggled to look into the shadows, "Ah, Orochimaru-sama, you're back!" ”

"Your strength has improved again, Hanzo." Orochimaru didn't answer, and said to himself.

"Thank you for the compliment, after all, you have to practice hard to better help you." The half-hidden stinky shameless showed loyalty.

"That's true, the higher your strength, the more suitable that thing is." Orochimaru was unexpectedly not like giving Hanzou a thorough look before, but he was serious and sure.

"What about it?" Hanzo grasped the key message in Orochimaru's words.

"I'm short on time to come back this time, forget if you're so tired today, start practicing with me tomorrow." Orochimaru didn't explain too much and turned back.

Although I don't know what I have to do by myself, I am still very happy to hear that Orochimaru is going to instruct me to practice Hanzo again, "After practicing for so long, it's time to do some actual combat, and those backlog problems are just solved at the same time." ”

In Hanzo's heart, he always thought that Orochimaru must have asked him to do some kind of combat mission next, otherwise he would not have paid attention to the factor of strength.

However, the reality slapped Hanzo hard, and the task in Orochimaru's mouth was a challenge, it was simply a tightrope walk, and the slightest mistake was fatal.

There was nothing to say all night, and Hanzo, who got up early in the morning, listened to Orochimaru talk about the arrangements for these days.

"Hanzo, I want you to master the "Elimination and Writing Technique" and the hidden techniques in these ten days." Orochimaru said solemnly.

"Orochimaru-sama, the two things you teach are not simple, and it is not easy for the latter to be used in practice, I'm afraid it will ......" Hanzo raised his doubts, afraid that the progress would not catch up, so he took a preventive shot first. Although Orochimaru doesn't teach combat things, Hanzo is not too satisfied, but it's better to learn a little than nothing.

"That's your problem, if you have the possibility of being exposed after returning to Konoha, I will deal with you before Konoha do. So for the sake of your life, you can do it yourself! Orochimaru said coldly.

"What! Back to Konoha? ”
