After lunch the next day, Kakashi and Dazna went to inspect the bridge that was still under construction, Sakura told Kakashi that he wanted to take the two of them to practice, so he didn't go, Kakashi would ask his happi dog to come over every hour to give feedback, so as not to be attacked again without support.

Seaside...

"Chakra is a combination of physical energy and spiritual energy, if the chakra is compared to water in a bucket, then the physical energy and spiritual energy are the baffle of the barrel, the amount of chakra will be determined by the short plank, your body has been personally recuperated by me over the years, naturally it will not become a short plank, so cultivating spiritual energy is today's topic, in my opinion, spiritual energy is far more than just a part of the chakra, it is also the speed of refining chakra, The key to controlling Chakra to form ninjutsu, take the writing wheel eye as an example, the writing wheel eye is actually the embodiment of Yin Dun, and the root of Yin Dun is spiritual energy, and the writing wheel eye can be released faster than others when copying other people's ninjutsu, this is a manifestation of strong spiritual energy, I say so, do you understand? Sakura asked the two of them after explaining.

"Understand" Sasuke himself is a user of the Sharingan, and after listening to Sakura's words, he immediately understood the key to it.

"Uh, Ming.. Understood," Naruto said after a pause, scratching his head.

"Naruto, you don't have to be nervous, everyone has something they are good at and what they are not good at, just work hard to do it," Sakura said to Naruto gently.

"Sakura-chan, you're so nice..."Naruto said movingly.

"Okay, then I'm going to teach you how to cultivate spiritual energy, among which the spirit will grow when the high efficiency breaks through the physical limit, and even more so encounters huge mental stimulation, which I believe Sasuke you have a deep understanding of, let's not talk about inefficient meditation and meditation, what I'm going to teach you is called "Soul Refining Heart Sutra" As the name suggests, the heart sutra of the soul is built, the effect is good, it is not stimulating, my spiritual sense, the ethereal fairy sound, and the means of teaching you the book of seals last time all come from this "Soul Refining Heart Sutra" Sakura looked at the two of them after finishing speaking.

"Ahh Yes. Ah, Sakura-chan, why didn't you pass on such a powerful technique to us earlier? If we had done it earlier, we wouldn't have had to be afraid to deal with that one last time if we didn't cut it down," Naruto said loudly.

Sasuke didn't speak, he knew that Sakura had always spared no effort to teach them, and it was extremely strict, there must be a reason for not teaching Naruto, this guy, an idiot blurted out extremely naturally.

"That's because cultivating the soul is dangerous, it is impossible for someone to guide you, everything can only rely on yourself, the slightest carelessness in cultivating into a vegetative person is light, and the heavy is the direct dissipation of the soul, how dare I teach you when you were young" Sakura patiently explained.

"Hehe, I'll just say Sakura-chan, you must be for our good," Naruto said with some embarrassment.

"Okay, without further ado, I'll pass on the Soul Refining Heart Sutra to you now, and you can cultivate by yourself," Sakura said, pointing her finger at the foreheads of the two of them.

......

Seeing that the two of them have entered the state, Sakura turned to look at the sea, she hadn't seen the sea for twelve years, and in her previous life, she would always go to the beach if the conditions allowed after completing the task, and in the last three years, she bought a seaview villa and lived by the sea, looking at the incomparably clear water in front of her, Sakura had already taken off her coat, leaving only a set of pale pink lace underwear into the water.

Looking at the sea water softening her body, Sakura could clearly feel the joy of her heart, she plunged into the water on tiptoes, swimming happily in the water like a mermaid, watching the schools of fish surrounding her, she seemed to hear their voices, although she couldn't understand them, she could feel their enthusiasm...

Sakura swam as she felt that the sea had become different, and she could see something she couldn't see just now, and the sea water was densely covered with colorless points of light, and these points of light actually entered her body when they touched her......

"Count God, what's going on? What are these points of light? Why does it get into my body? Why don't I feel anything at all? Sakura couldn't figure out the situation, so she had to ask for advice.

"These points of light should be things like water spirits, as for why they enter the host's body, to be precise, it should be the host's body that attracts these water spirits, this should be the reason why the host cultivates the "Weak Water True Decision", it is recommended that the host run the "Weak Water True Decision" This can increase the host's attraction to the water spirit, and these water spirits can increase the host's water system affinity after entering the host's body, which is of great benefit to the host's cultivation" Shushen immediately analyzed.

"Oh, okay" Sakura immediately began to run the real decision with all her strength as soon as she heard that it was good for her, and those water spirits also began to scramble to drill into Sakura's body......

On the beach at this time......

"Hey, where's Sakura-chan?" Because Naruto practiced the Soul Refining Heart Sutra for the first time and his heart was not calm enough, he automatically quit his cultivation in less than half an hour.

"Huh? This is Sakura's clothes" Naruto immediately saw the clothes next to him, which Sakura had put there.

"So Sakura is swimming, hahahaha," Naruto muttered to himself, and started laughing.

"Idiot, what are you arguing about?" Sasuke has a natural advantage in cultivating the Soul Refining Heart Sutra because of the Uchiha clan, and when he was still immersed in cultivation, he was suddenly interrupted by Naruto's laughter and quit his cultivation, and then said angrily to Naruto.

"Sasuke, Sasuke, look at what this is?" Naruto took Sakura's clothes and said excitedly to Sasuke.

"Huh? This is Sakura's clothes, is she swimming? Sasuke immediately understood, and looked at Naruto.

"Hehehehe... Hahahaha" The two brothers suddenly laughed weirdly, and then strippers...

"Sakura-chan, Sakura-chan, Sakura-chan, where?" Naruto looked at the sea and didn't see Sakura's figure, and kept muttering.

"Maybe underwater, let's go down and see," Sasuke guessed, and Naruto was the first to dive into the sea.

The two looked around in the sea, but still couldn't find Sakura, so they had to go to the water to ventilate first.

"Why is there no one in the sea, Sakura won't go back, right?" Naruto wondered.

"Idiot, how is it possible, let's not say that we are cultivating and she can't go too far, let's just say that her clothes are still on the shore, she can't go back in her underwear," Sasuke said.

"Then I'll have to look deeper," Naruto also thought that Sakura wouldn't leave.

"Well, hurry up, if she is really in the sea, there is a good chance that something will happen if she hasn't come out for a long time, we have to find her quickly" Sasuke felt a little wrong at the moment, and he couldn't care about taking advantage of it.

"Well, let's go down," Naruto said solemnly.

When the two of them went down to the water again, they finally saw Sakura's figure, but she seemed to be unconscious now, slowly sinking, and what was even more terrifying was that her body was slowly becoming transparent......
