Time passed quickly, but this period of time was quite long for Sakura, because it was painful every few days, and that feeling, if it wasn't for Sakura's determination, ordinary people really couldn't bear it.

On this day, Xiaomei looked at Sakura, who had obviously lost a lot of weight, and said distressedly: "Sakura, don't do this anymore, your body is really..."

"It's fine!"

Sakura was a little weak, and the last few times, she shortened her rest time and her body was almost at its limit. However, she was still gritting her teeth and insisting. Because, she vaguely felt that the Yin Seal in her body had gathered, and Chakra was about to reach the bottleneck.

At this moment, even though her body was almost at the limit, her eyes were still full of madness.

Grabbing a handful of tender leaves, she ate them in her mouth, and in a moment, the curse mark spread from her neck again.

The intense pain finally brought her body to the extreme.

Poof, with a mouth, it's just a mouthful of blood that spits out directly.

"Sakura-chan, Sakura-chan, don't torture yourself like this, stop!"

Sakura-chan wiped the blood from the corner of her mouth with a pale face, and she gritted her teeth and said, "I can feel it, this is the last time." After this time, my Yin Seal Chakra should be enough... Ahh

Halfway through that, the cramp-like pain caused by the curse mark made her scream unbearably again.

Sakura is so stubborn, and Mei has no choice, she can only frantically perform medical ninjutsu for Sakura.

…

This time, in the distance, Daimi, Granny Slug, and Tsunade Hokage all came.

Tsunade Hokage looked at Sakura like this and felt a little distressed.

"Sakura-chan has been using this way all this time?"

"Yes, this child, in order to become stronger, she can endure such a great pain... It's just deadly. ”

Tsunade Hokage regretted it a little. "I knew that Sakura couldn't wait for 3 years, so I shouldn't have taught her this forbidden Yin Seal. ”

Granny Slug shook her head and said, "I'm afraid that even if you don't teach her the Yin Seal, she will be so desperate to learn other ninjutsu." I could feel something from her that other ninjas didn't have, very urgent, and not slack off in the slightest. ”

Tsunade Hokage stopped talking, as Sakura's pain continued in the distance.

…

Eventually, Sakura's pain was over, and the black curse mark that looked like a tattoo turned into a scorching flame again, and all of it was retracted to Sakura's neck and shoulders.

Sakura's body was once again like it had been fished out of the water, sweat from pain, and even her long pink hair was wet. When her already weak body was about to fall, Tsunade Hokage suddenly appeared, and her body flashed, just past, and Sakura fell into her arms.

Tsunade's arms were naturally extremely soft, Sakura's pale face was buried in it, and she turned her head sideways. "Thank you, Tsunade-sensei. ”

Tsunade Hokage looked at Sakura distressedly. "You are so stupid, if you wait for 3 years, why use such a painful way to speed up the time for the Yin Seal to gather Chakra. ”

Sakura just smiled, she didn't answer the question, because the things about the main quest, and the things about her 'previous life' doing evil and now atonement, are her secrets, and besides, she can't explain it clearly.

Sakura took a deep breath, then continued to lean her face against Tsunade's soft and warm arms, and then smiled at Tsunade Hokage:

"Tsunade-sensei, I've succeeded, I've finally succeeded! Just now, my Yin Seal Chakra has finally been gathered!"
