The Sage Mode cannot be achieved in a day, even if one has spent several months building up the perception of natural energy.

If possible, Shuimu also wanted to do nothing for ten days or half a month and just vacation here... No, it should be spent guiding his disciples in their practice.

However, it seemed inconvenient for an adult man to stay on an isolated island with a little girl of fifteen or sixteen.

Shuimu is not an unkind person.

As long as there was nothing else to do, Mizuki would take Sakura to this remote place in the morning and bring her back in the evening.

I don't know why Uzumaki Naruto stayed there and didn't come back when he was practicing Sage Mode in Myoboku Mountain. He had the very convenient Reverse Summoning Technique to travel freely, but he insisted on staying overnight and eating insects with Sage Shima and Sage Fukasaku.

Shuimu has the more convenient Flying Thunder God Technique. If it is not absolutely necessary, Shuimu does not want to sleep in the open in such a place.

I am just a ninja, not an ascetic monk, there is no need to cause trouble for myself.

Of course, Mizuki also wanted to teach Sakura the Sage Mode as soon as possible.

But this kind of dangerous practice cannot be done quickly. Shuimu has to pay special attention to any small accident. Physical injuries are easy to treat, but mental problems are not so easy to deal with.

Fortunately, although practicing Sage Mode puts a lot of pressure on the mind, it has little impact on the body.

For Sakura at the moment, her physical weakness is not yet obvious, and the weakness of insufficient chakra is compensated by the Breath Containment Technique.

As long as Sakura doesn't lose her composure, studies step by step, and then learns the Sage Mode naturally, there shouldn't be any problem.

"Master, do you think I have succeeded?"

A week later, Sakura finally managed to master the trick and excitedly reported it to Mizuki.

"Um……"

Mizuki looked at Sakura's condition.

"How should I put it? There is some progress, but it takes more than three minutes from sensing natural energy to forming Senjutsu Chakra. If this were in actual combat, who would you expect to buy you time? Who would protect you during these few minutes?"

Shuimu's Sage Mode is activated very quickly, because Shuimu is not picky about natural energy and accepts it all. As long as the control ability is good, the Sage Mode can be activated very quickly, but the side effects are known to everyone who uses it.

Sakura is different. The range of her absorbing natural energy is much smaller than Mizuki's, and the power of her Sage Mode cannot be compared with Mizuki's. She can only wait and see how it gets strengthened slowly in the future.

But this is not a reason for Shuimu to lower his requirements.

Three minutes? It was enough for the enemy to kill him several times. He couldn't just brush it off like that this time.

"Still not working?"

Sakura was a little disappointed. It was not an opportunity to have a powerful jonin teach her a secret skill step by step for a week. Even between a master and a disciple, such scenes were rare.

"This is a practice that completely tests your control ability and experience. I don't have any better methods. You can only rely on your usual accumulation to gradually improve. Put this aside for now. I don't have much time to wait for you to practice slowly. I will leave the others to you first..."

The Sage Mode has greatly improved the basic qualities, and the power of ninjutsu mixed with natural energy and senjutsu chakra will also be greatly enhanced.

There are also methods like Frog Kumite that control natural energy to assist in combat. How to use natural energy that is invisible to the naked eye and extremely difficult to perceive to attack the enemy are skills that require rich experience to learn.

All of these need to be carried out simultaneously with the practice of Sage Mode, and the one that Sakura needs to master the most is the Sage Method: Inorganic Reincarnation Technique.

As long as you learn this technique, you will at least not be useless when facing a strong enemy in the future. The magic that Uchiha Itachi could be killed by when he was not careful is not a simple thing.

“Is there still so much to learn?”

Sakura originally thought that she had already entered the realm of mastery, but she didn't expect that she was not even at the beginner level.

"Before this month, you need to master these first. This special training will come to an end for now. You can practice slowly in the future!"

"By the way, how far have you progressed in practicing the transformation of chakra attributes?"

"Earth and water are done!"

“A bit slow!”

Shuimu muttered to himself, not even thinking about how many training tasks he had arranged, and whether he had enough time to carry out this kind of basic training.

"Next, practice the changes in the properties of fire-attribute chakra as quickly as possible, and then there are important things to learn!"

"besides?"

Sakura made a bitter face and couldn't help but complain.

"Stop talking nonsense and just watch carefully!"

In a moment, a wave of chakra surged out, the Sage Mode was activated, the right hand was spread out, the Rasengan took shape instantly, and then the Five-Tails Chakra was injected, and the light blue chakra ball turned into a rotating mist-like steam ball.

Shuimu casually pressed it to the ground, and with a violent explosion, a large pit four or five meters deep and more than ten meters in diameter appeared on the road paved with thick granite slabs.

"Is the Rasengan so powerful?"

Sakura was surprised. She had never thought this technique was so powerful before.

“You try it!”

Sakura followed her instructions and injected a little senjutsu chakra and the Five-Tails King's chakra into the Rasengan, attacking the hard ground.

With a loud bang, another deep pit appeared, but the damage caused by Sakura's full-strength attack was not even half of that caused by Mizuki's casual attack.

"Just now I just wanted to let you know the difference. In fact, this is how it should be used!"

Mizuki suddenly threw a punch at the ground. The violent vibration made Sakura's feet fly off the ground. Then she was pulled up by Mizuki and flew in the air.

Amid the loud roar below, a protruding corner of this not-so-big island quickly shattered and sank to the bottom of the sea in front of Sakura's stunned eyes.

"Immortal Technique·Boiling Escape·Unparalleled Strange Strength, what do you think?"

Mizuki's original bloodline limit is lava jutsu, and boiling jutsu can only be used with the bonus of Sage Mode and by borrowing the chakra of the Five-Tails King.

"Boiling Release, is it a bloodline limit? Master wants me to learn this? I can't do it..."

For a civilian ninja from an ordinary family to suddenly say that he wants to develop a bloodline limit is such a subversive thing that is really hard to believe.

Mizuki ignored Sakura who seemed a little unsure and spoke to himself.

"Due to different understandings, boiling jutsu has many different forms. What I just used is the secret technique of the Five-Tails, which instantly boils the chakra and concentrates the power of the whole body to produce a bloodline limit of great destruction!"

Since I haven't learned Tsunade's super strength, using Boiling Release instead shouldn't be too much of a difference.
