Although he was in danger, Shuimu didn't feel too anxious. Everything was just his guess, and he had already prepared a plan for a rainy day. All he had to do was act according to circumstances. Maybe the situation wasn't that bad.

So, we still have to do what we have to do. Life cannot be crushed by unknown troubles. What's more, we have a wife and an unborn child at home. How can we panic?

Shuimu still lives a life of going out early and returning late every day. During the day, he either stays in the Death Forest for field surveys or sits in the office to design barrier arrays. This kind of life reminds Shuimu of his days as a social animal and technician in his previous life. This long-lost experience also makes him feel very emotional.

Fortunately, the work of transforming the barrier has not yet been fully launched. Since such a big change is to be made, then we can simply redesign it. This kind of theoretical thing is not the older the more valuable it is. The truth that has been passed down through the test of time is the cornerstone of development. Regardless of the difference in power level and quality, the new barrier must be stronger and more efficient than the previous one.

As for Danzo, there is no need to be too anxious for the time being. It will be in time to let his subordinates join when the barrier is almost completed. Now the people in the barrier team are enough.

During the remaining rest time, Shuimu often accompanied Xiaochun for a walk, and the days were relatively peaceful.

…

On a somewhat cold rainy night, Shuimu pushed open the door of the tavern, looked up and around, and after finding the direction, he walked straight over.

"You're here, Mizuki." The one who spoke was none other than Hatake Kakashi who had been waiting for a long time.

Mizuki didn't hesitate and walked over to sit down opposite Kakashi.

"You don't seem like someone who likes to come to the tavern. Why would you want to treat me?"

"I just came back from the Rain Country not long ago. I want to drink some warm wine to warm myself up."

"The Land of Rain?" Mizuki frowned, "Sending an invitation letter for the Chunin Exam?"

"Yes, going to the Rain Country at this time of year is not a good idea."

"Hanzo the Salamander is not an easy person to deal with. And there are rumors that the situation there is very complicated. There are big wars outside and small wars in the Rain Country. It has never been peaceful. Even a person like Hanzo can't stabilize the situation."

Hatake Kakashi shook his head and said, "What I saw this time was a little different. I didn't find the chaos that was rumored. It is true that the security is very tight. There is no chance to move freely, and it is even more of a luxury to ask for any information."

"You saw Hanzo?"

"I was introduced and heard the voice, but I didn't see him in person." Hatake Kakashi shook the remaining wine in the white porcelain bottle in his hand, then filled his own glass and then filled Mizuki's glass. "You asked this because you heard the rumor, right?"

"Hanzo hasn't made a public appearance for a while, and there hasn't been any new news. It's normal for him to arouse suspicion. It's really dangerous for you to go to the Rain Country at this time!"

Mizuki was not just suspicious, but had long known that Salamander Hanzo was dead. Now that Nagato was in power, the Rain Kingdom was shrouded by the Rain Tiger's Freedom Technique. If there was really a fallout, there would be no way to escape.

"Would you ask me to go if it wasn't dangerous?" Kakashi was aware of being a jonin of Konoha. "Isn't that what we do?"

"That's right." Shuimu picked up the warm wine glass and drank it all. "Tell me, what do you want to talk to me about? You're not going to buy me a drink just to complain about the hard work of the mission, right?"

"If you let Sasuke lead it for me, I've thought about it for a long time and decided to let him improve his basic strength first and suppress the Sharingan temporarily!"

"It's up to you and Sasuke to decide. I have no opinion." No matter which path you choose, you will eventually reach the end. The only difference is the impact on Sasuke's mentality.

"I've tried the Mind Concentration Scroll, and it's really effective. It's really good for some basic training, but it's not without risk."

"It's always bad to over-exert mental power. I'm afraid the little guy won't know how to control himself, and might cause any harm."

"You are indeed a sensible person." Kakashi nodded, "That's what I'm worried about."

The concentration technique to calm mental fluctuations is not omnipotent. In principle, this technique does have a good defense against external mental shocks, and is very strong against the damage caused by the shadow clone. However, after a part of the mental fluctuations are calmed, the energy will still be slowly released inside. After using this technique to a certain extent, it is best to rest properly instead of overdrawing.

Just like in a sprint event, high-speed sprinting consumes a lot of physical energy in a short period of time, which will make people fall into a state of extreme discomfort. If this consumption is flattened and slowly released over a long period of time, and then offset by the body's own recovery ability, its impact can be minimized.

The effect of the concentration technique is to slowly release the large amount of damage accumulated by the shadow clones in a short period of time, and then buffer it with the body's recovery ability so that it will not be overwhelmed by the sudden mental damage. As long as there is proper repair afterwards, there will be no harm. Of course, it is different for the Uchiha clan. This situation is very disadvantageous for people with the Sharingan talent.

Another problem is that when mental exhaustion is already very great, this technique will give people the illusion that they can still hold on, and then excessive overdraft of energy may cause even greater trouble.

Mizuki had long known about Kakashi Hatake's worries. Mizuki had carefully reminded Sakura about the taboos of use, but Mizuki was unsure about Sasuke. He was neither his disciple nor his student, so it would not be good for him to interfere without permission.

"I can't think of a good way to solve this problem. After all, I can't keep an eye on Sasuke all the time."

"So you just left him in the Forest of Death?"

"You know all this?"

"You just came back not long ago, you don't know yet! The Death Forest barrier is being transformed, and I'm the one who implemented it. How could I not know? Even if it wasn't me, it's already this time, and it's a high probability that I'll be discovered!"

"The Chunin Exam?" Hatake Kakashi said, "It seems we can't let him wander around in there anymore."

It was getting late, Mizuki said, "Don't worry too much about Sasuke. Sakura hasn't learned the Concentration Technique yet, so it's impossible for Sasuke to monopolize the scroll. Sakura's training tasks are very heavy, and she doesn't have that much time to accompany Sasuke all the time. Even if Sakura loses her mind for a while, I won't let the assessment tasks here go unattended."

"Indirect control? Thank you, Mizuki."
