"How come your pants are half off. Did you wet the bed."
Ryun struggled to try and sit up, but Sakura only needed one hand to press Ryun back onto the bed.
He still wanted to say something, but what he got in return was Sakura's warm embrace. "Don't move. It's my turn to take care of you now."
"You must have suffered a lot being alone in Sunagakure... I'm sorry, I couldn't bring you back."
"But it's alright now. I'm here."
Sakura looked at the skin on Ryun's body, which had become much rougher because of the wind and sand, wiped the joyful tears from the corner of her eyes, and straightened Ryun's clothes.
As for any possible odor on Ryun, it had long been covered up by the strong smell of alcohol on both of them.
By now, Ryun finally understood what had happened today. Sure enough, it was the fault of the alcohol.
However, Ryun also had to admit.
With his sufficiently strong Yang attribute chakra, he was not afraid of a battle of attrition at all.
Instead, Sakura, who could normally punch most enemies away, was now as weak as a leaf at this moment.
Perhaps this was Sakura's unique tenderness.
After a long time, Ryun waited until Sakura fell into a deep sleep, embraced her and closed his eyes as well, finally withdrawing his consciousness to do more important things.
In the simulation, Sakura spent the next year explaining to Ryun in detail how all of Tsunade's S-rank ninjutsu functioned.
What Ryun needed to do now was to review all the details again, striving not to miss anything.
The core of Tsunade's ninjutsu system is the Yin Seal. Arranging a sealing technique on the forehead allows one to store the chakra usually refined but not immediately needed.
Furthermore, by fine-tuning the Yin Seal, the possessor of the Yin Seal can achieve effects like accelerated healing, enhanced attacks, and increased speed in their normal state.
Ryun had reason to guess that the purpose of Tsunade developing this technique was to imitate Senju Hashirama, hoping to achieve the practical combat effects of Hashirama's Sage Body.
There is another function of the Yin Seal that must be mentioned. That is, it can also enhance bodily functions, keeping them in peak condition, even achieving the effect of eternal youth.
Ryun is still young now, perhaps he doesn't need this effect yet.
But he guarantees that no female ninja in this world would want to refuse such a ninjutsu.
It's just a pity that too few people can learn it.
However, Ryun could use the talent transfer method to give those around him a chance to learn this technique as well.
After the Yin Seal is released, the chakra within it is released. At that time, the ninja can consume this chakra to use super high-powered ninjutsu they would normally be reluctant to use.
For example, Tsunade can use this method to summon a slug four or five stories tall, and have the slug use medical ninjutsu to treat the wounded of the entire village.
Of course, the most important function of Yin Seal: Release is still to provide support for the subsequent Strength of a Hundred Technique and Creation Rebirth.
Once the Strength of a Hundred Technique is activated, curse marks will densely cover the body. These curse marks automatically consume chakra to heal the ninja, almost allowing the ninja to ignore the vast majority of injuries.
As for Creation Rebirth, it can instantly heal fatal injuries by consuming cell lifespan, even allowing recovery from being cut in half.
However, Creation Rebirth requires the ninja to perform hand seals to activate it. This is probably the only weakness of this technique.
Having sorted out Tsunade's entire ninjutsu system, Ryun couldn't help but find it interesting.
Ryun and Tsunade haven't met yet, but he has already learned all of her ninjutsu.
In the future, when Ryun meets her, what kind of expression will Tsunade have when she discovers Ryun has already learned the Yin Seal.
Ryun really wants to know, and he isn't afraid of clashing with Tsunade. After all, he will only try it in simulations first.
What Ryun needs to do next is already self-evident.
He wants to train the Yin Seal.
It can be said that ever since Ryun obtained the simulator, he has been constantly thinking about this ninjutsu.
Learning it can greatly alleviate Ryun's survival pressure. After Ryun accumulates chakra for several months, he might even be able to unleash combat power reaching Kage level.
At that time, no matter who it is, it will be very difficult to casually control Ryun's fate again.
There's just a small problem right now. That is, Ryun cannot place the Yin Seal on his forehead.
Because once he has the diamond-shaped mark on his forehead, Ryun would be telling everyone that something is up with him.
Ryun still doesn't want to fall out with Konoha right now. He still needs to keep developing until the Konoha Crush Plan begins.
So Ryun decided to relocate the diamond-shaped mark to his chest. In daily life, wearing an extra dark-colored undershirt can avoid most troubles.
However, relocating the position of the Yin Seal is not an easy task. Even Tsunade herself would find it very difficult to perform, because it involves how to arrange the entire set of sealing techniques.
The time and energy wasted on this is simply not something a ninja could endure.
But coincidentally, Ryun in the simulation has enough time and energy to research this matter. He has even spent more than one simulation on this.
Plus, he has Chiyo's legacy. Chiyo herself is also a master in medical ninjutsu and sealing techniques, and her skill level isn't much weaker than Tsunade's.
All these factors stacked together are enough to give Ryun the courage to attempt it.
And even if he fails, it doesn't matter. At worst, Ryun can just start another simulation. After all, he still has three simulation attempts left.
Thinking of doing it, Ryun took off his clothes, created a shadow clone, and had both himself and the shadow clone use chakra to inscribe the sealing formula on his chest and back simultaneously.
A full hour later, Ryun put his palms together, and the seals all over his body lit up.
The seals absorbed the chakra from Ryun's body, then quickly contracted towards Ryun's chest. Finally, with a light shout from Ryun, a diamond-shaped mark condensed there.
Did it succeed.
Before Ryun could even feel happy, the diamond-shaped mark exploded the next second, blasting Ryun away and slamming him into the wall.
He winced in pain, then pulled himself out of the wall, moved his joints and bones, and a smile appeared at the corner of his mouth.
He had indeed failed just now, but it wasn't a failure of the idea. It was a failure in the fine-tuning of the chakra balance.
Faced with this kind of failure, he just needed to keep trying.
For this, Ryun set a small goal for himself. He would try until early morning.
If he failed again, he would resolve it in a simulation.
Time passed minute by minute. Ryun made a total of seven or eight attempts.
Finally, at the moment the sunlight shone through the window illuminating Ryun's bedroom, a diamond-shaped mark appeared on Ryun's chest, resting there quietly like a gem.
Ryun weakly lay down on the bed, feeling the chakra flowing in his body slowly converge into the Yin Seal, and slowly clenched his fist.
If obtaining the simulator was the first major turning point in his life, then obtaining the Yin Seal was the beginning of him truly becoming a strong ninja.
Just as he wanted to close his eyes and rest for a while, a hurried voice came from above him. "Ah Ryun, how are you injured."
