There are many choices in life. From life events to trivialities.

Even every day when you go to bed, you need to make a choice, do you close your left eye first, or close your right eye first?

Of course, Masahiko generally does not hesitate and chooses to close both eyes at the same time.

But the choice he was facing now was a difficult one. Genetic modification and synthesis skills are added to level 8, and a bunch of black technology methods are added, and they can even perform anti-aging surgery on people, helping people prolong their life by 60%.

And what about level ten?

Masahiko was looking forward to it, but adding to level 10 required 900 witness points, which was not a small amount. Moreover, Masahiko is only 1,500 witness points away from reaching the full-level tuba achievement, and all eight spaces are open......

"It still depends on how many witness points can be obtained in the next few days, and the specific effect of this anti-aging surgery."

As the night deepened, Masahiko used his eighth-level genetic knowledge to conduct a detailed examination of Yuhuo again, gave her a promise that it could be cured, and asked her to go home to rest and have a good dream.

Masahiko built a wooden house next to her house and planned to rest here for the night. That night, he closed both eyes at the same time.

……

Following.

Masahiko returns to Konoha with a fishing fire.

The little girl didn't have anything to worry about in the land of the sea, so she said she would leave. And in addition to not going to the strongman to make it difficult for the Daimyo of the Sea Country to change the name of the strange island to Saburo Island, the other goals have basically been achieved, and there is nothing to be nostalgic about.

It's a pity that Orochimaru's child is not easy to crutche, and Masahiko is still quite optimistic about the red lotus, cultivating and cultivating, and the prospects are good. As for Tayuya, a girl who covets the beauty of her ancestors, don't do it!

"The Great Snake Pill has been 'hidden', these two people can't wait for two years, can they wait for a lifetime? Sooner or later, abandoned children will have to fall into the arms of their ancestors...... Ahem, come in the bowl! ”

Riding the flying carpet all the way, the fishing fire is not afraid of heights at all, and the scenery is full of smiles on his face when he watches the scenery from the air. It's only now that she believes that Little Brother is an amazing ninja......

After arriving in Konoha, Masahiko went straight to the Uchiha clan with the fishing fire. The proper way to remove the fish gene for her has been summarized by Masahiko, but the specific treatment is still good for Lin......

Originally, I was going to Lin, but I didn't expect to see a more suitable person in her house.

"Tsunade, when did you come back?"

Tsunade was holding Xiao Ming in his arms, and when he saw Masahiko, he was stunned, and after turning his head and getting Lin's confirmation, he suddenly showed a bright smile: "Haha! Grandpa Gao, you have really become smaller, so cute! ”

handed Xiao Ming back to Lin, she stepped forward and wanted to give Masahiko a hug, but Masahiko hurriedly refused.

"Don't make a fuss! The height is not right! ”

"Oh, you're going to be shy!"

Masahiko: "......"

After a laugh, Tsunade slowly explained the reason for returning to Konoha.

There are many reasons for this. Orochimaru attacked Konoha, and life and death were uncertain. The day is getting older and older, and there are no more than two years to live. Rin is pregnant and has a child, and even Masahiko is getting smaller...... Of course, the main reason is that Jiraiya found her and told her this.

Different from the original book, Tsunade has a lot of concerns in Konoha Village now, and it's just a matter of gambling outside for two years without heart and lungs, and it's too unreasonable to keep gambling, so she returned to Konoha with Jiraiya yesterday afternoon.

"There is a more important reason, you and Jiraiya are not young."

Tsunade paused, and the corners of his lips hooked: "Haha, Grandpa Gaozu, come and hug one!" ”

Masahiko: "......"

There was another laugh, and it wasn't until Tsunade asked about the fishing fire that Masahiko remembered what was going on.

"She is a poor little girl who has been poisoned by the big snake pill tea, and I brought her back this time. I wanted Lynn to help her with treatment, but now that you're back......"

"Orochimaru tea poison, treatment?" Tsunade frowned slightly, and walked towards the slightly restrained fishing fire.

Masahiko soothed: "Don't be afraid, this is Tsunade, and Orochimaru belong to the same Konoha Sannin, and her medical skills are excellent, she will cure you." ”

Yuhuo was stunned for a moment, and almost turned around and ran away......

Masahiko smiled: "Konoha Sannin is not all bad people...... Well, it's pretty much the same, you're the only good guy in front of you. ”

Yuhuo couldn't run away if she wanted to, and was grabbed by Tsunade's wrist, and as soon as Chakra was slightly stimulated, she gradually revealed her fish-man form.

Lin, who was holding Xiao Ming on the side, immediately opened her mouth in surprise.

"Orc experiments?" Tsunade raised his hand and touched the fins on the top of Yuhuo's head, "Orochimaru, bastard...... I can cure it, but ......"

"I'll teach you how to treat it for a while, there are no side effects."

Tsunade was stunned: "When did you learn about genetics?" ”

"Heh, Grandpa Gaozu can do anything."

"Then why don't you treat her yourself?"

Masahiko scratched his head: "It's not convenient for me to treat some parts of her fish genes. ”

Tsunade curled the corners of his lips: "Is this little girl 20 years old?" It's not even a fraction of yours, when did you become so innocent? Is it because you're getting younger? It's so cute, come and hug one! ”

Masahiko's face darkened: "Bastard! ”

……

It was at Lin's house that Masahiko instructed Tsunade to perform the first treatment of the fishing fire.

Unable to see the little girl crying because of her improved health, Masahiko pulled Tsunade aside and told her about the anti-aging surgery.

"Really?!" Tsunade whispered, "Extend your life by 60%, how is this possible, wouldn't everyone live to be more than 100 years old......"

"Not necessarily, depending on his age. For example, Jiraiya, who is 50 years old this year, oops, is 50 years old! ”

"Grandpa Gao, you don't come to this set!"

Masahiko smiled: "For example, if he can live to be 80 years old, he still has 30 years to live, and a 60% extension of life is 18 years, 18 more years!" ”

Tsunade pondered for a moment: "So, the sooner you do this surgery, the better?" ”

"Not necessarily." Masahiko shook his head: "Whether it will delay development or not, it is still uncertain." ”

"Then you tell me ......?"

"Teach you, the aging gene is all over the body, and I can't operate on them without Jiu Xinnai."

Tsunade nodded, this time he didn't 'tease' Masahiko, and he could distinguish the priorities.

"Do you write down what you need me to know, or do you just teach me?"

Masahiko waved his hand: "You can follow me for an operation." As for the target of the surgery, let's use it! ”

Tsunade: "......"

The routine is really deep.

"Don't worry, this operation will have to be done after the year, and I still have to verify it."

Tsunade said she wasn't in a hurry.

It was the middle of December of Konoha 60, and for the next half month, Masahiko experimented with this anti-aging surgery.

He didn't find the test subject, so he brought disaster to himself. At the end of Konoha 60 years, he finally stumbled and eliminated all 268 aging genes on his body!

"Even if there is no system now, the ancestor can live for another 128 years!"

"I don't know if there are any side effects, my ancestor is dedicating himself to science......
