"Knock knock", there was a knock on the door of the World Room. By this time, the time had come to the next morning. In order not to attract the attention of the Summer Family, the three of World, Madara and Izuna did not step out of the room. All the washing and stuff was done with the reserves in my own storage scroll.

"Come in!" Inside the door, Madara's voice was heard.

"Zila~", with a sound of wood rubbing, the door of the world room opened.

"Miss World, regarding the matter of the bet, our patriarch is ready." Yesterday, the summer sun of the Summer Clan bowed his head slightly to the world and said.

"I see." The world smiled at him and nodded.

"I heard you!" The world stood up from the wooden floor and said to Izuna, who was wiping the Uchiha fan and cultivating the chakra fire escape in his palm, "Let's go, here comes the business!" ”

After saying that, the world followed Xia Riyao. And Madara and Izumi, on their part, also began to let go of what they were doing and followed behind the world.

"Knock~knock~knock~", walking with the world behind Xia Riyao, he suddenly ran into two ninjas head-on. The two ninjas looked depressed and walked over carrying a stretcher. Although, from the naked eye, the man covered with a white cloth seems to be dead. However, from Chakra's point of view, he or she is still alive.

"Is that dead man one of your people?" The world asked probly.

"That's right!" It seems that because of yesterday's hospitality, the ninjas of the Summer Clan are not very wary of the world now. "Every year, several children of our clan are sacrificed because of the cultivation of the family's secret arts."

"Secret arts?" The world behind him glanced at Madara, and then asked, "Do you know about medical ninjutsu?" ”

"Medical ninjutsu? What kind of technique is that? Xia Riyao asked the world.

"Uh~", the world explained: "You can understand it as a ninjutsu specifically used to save people. Just when I passed by the child, I realized that he was not dead, he was still alive. ”

"Wait!" Xia Riyao was stunned for a moment when he heard this, and then hurriedly asked, "Can you really save him?" ”

"Hmm!" The world stared into his eyes and nodded naturally.

"Festival, calendar, you two wait a minute." Hearing the words of the world, Xia Riyao immediately stopped the two who were carrying the corpses.

"Brother Yao, what's wrong?" The young ninja who was called off, Summer Festival, asked in confusion at Summer Shine.

"World Patriarch, please help save this child!" Xia Riyao excitedly brought honorifics and said respectfully to the world.

"Hmm!" The world did not hesitate to respond, and uncovered the white cloth of the young man draped on the stretcher. Judging from his appearance, this young man's appearance is okay, and his age is about the same size as Izumi. Thinking of this, the world sighed and began to examine it carefully.

"Brother Yao! This is ......", the two young ninjas asked puzzled by the scene in front of them.

"We'll talk about it later!" Xia Riyao shook her head at them.

And here, the world that began to use medical ninjutsu to examine the boy's body showed a hint of surprise on his face. "This sickness! Is this their secret art? ”

Thanks to the pupil power of the kaleidoscope writing wheel, although the world did not find the cause of the teenager's body, but through the vision at the cellular level, the world could easily see the body cells of the twelve or thirteen-year-old boy in front of her.

So, when the world used the power of chakra perception to spread all over the boy's body. In this case, she can grasp everything about the teenager's exterior clearly. "It's not an external injury, so it's not a secret technique of physical exercise." With this, the world came to its first conclusion.

"Hmm~, there are no traces of the effect of drugs in the organs in the body, and it seems that the injury is not caused by drug-based cultivation." Looking at the red spots on the boy's body, the world pressed lightly. The red spots then ooze blood.

"According to their Summer Clan, this is caused by the cultivation of secret arts. Then, the cultivation of this secret technique is too cruel. Eventually, after collecting a large amount of cellular information from the teenager, the world finally knew the cause of the disease.

"Cell collapse", under the pupil power of the world, the teenager's cells present a picture of continuous collapse. Among them, one cell belongs to the teenager himself, and the other cell seems to be derived from the mutation of the teenager's own cells. It's strange that the cells of the teenager who seem to have gotten something have begun to mutate, and the cells under this mutation will become very powerful. However, there is a limit to this strength, beyond which the original cells in the body will reject the mutated cells. Thus, the cell-to-cell battle begins.

"Whew~", after understanding the illness of the teenager in front of him, the world stood up and exhaled. "It's unprecedented, it's really unusual!" , The world's face showed a hint of thought, for the world, this kind of cell collapse disease is the first time she has encountered.

"World Patriarch, how is this child doing?" Xia Riyao asked the world in a low voice.

"With my medical ninjutsu attainments, there is still hope that this child can be saved." The world said to the three members of the Summer Clan, "Don't worry, I'll heal him." ”

"Thank you, World Patriarch! But ······", Xia Riyao obviously remembered the clansmen who were still waiting for the three people in the world for a gambling contract.

"His illness is not acute. So, I only need a few minutes to relieve his physical condition, and as for the subsequent treatment, it can be placed after this bet. The world said to Summer Sun.

"Whew~", Xia Riyao nervously looked at the green light in the world's hands. Finally, he exhaled and said, "The Summer Clan, finally saved. Patriarch of the World, please come with me! After completing a series of actions in the world, he saw that the young man of the same clan began to have a normal face, and his breath began to stabilize. So, he stood respectfully in front and led the way for the three people of the world.

The summer clan's clan land is not very large, compared to the Uchiha clan's population of thousands of people, the summer clan is still a small family with little name after all. If it weren't for the so-called "stars", the Uchiha clan would not have had a relationship with such a small family at all. After experiencing the incident of the teenager whose cells collapsed due to the cultivation of secret arts, the three people of the world, led by Xia Riyao, soon came to a clearing outside their Xia Ri Clan's village. At this time, almost all the ninjas on the side of the Summer Clan have been waiting for a long time.

"Excuse me!" The world said with a smile on its face. "There was a delay on the way because of something. So, let's get started! Standing in front of more than a dozen Summer Ninjas, he said with no fear on his face.
