The upgrade system of all realms starts from conquering Naruto

"Natsume Yang, can I spar with you once?"

Metkai's face was filled with anticipation and he bowed to Natsume Yang.

Although he knew that Natsume Yang would probably reject him, he still wanted to give it a try.

He still remembered that when he proposed this idea, everyone except Kakashi said that he was wishful thinking and a waste of effort.

But Metkai didn't care, he just wanted to give it a try. How would he know the result if he didn't try?

One second!

Two seconds!

Three seconds!

Metkai felt that his heart was about to jump out, and he was sweating profusely from nervousness. "Natsume Yang hasn't answered for so long. I guess there is no chance." He thought in his heart.

He looked forward to a miracle, although he knew that it would be difficult for a miracle to happen to him.

But as long as there is a slight possibility, he is willing to give it a try.

"Can!"

Metkai didn't know if he heard it wrong. He raised his head in surprise, only to see Xia Muyang glance at him, then turn around: "Follow me!"

"Thank you so much!"

Metkai couldn't help but bow again, and then quickly followed.

"Just right here!"

Natsume Yang took Metkai to a flat ground, stood with him separately, and signaled that he could start.

"I'm on it!"

At this period, Metkai was not very good, and he could only pass the Chunin level, and there was nothing outstanding about him. If he and Kakashi were not close to each other, no one would know him at all.

"boom!"

After all, because he had not received professional training, Metkai's power was a bit unskilled and he did not fully utilize his power.

Xia Muyang raised his leg to counter him with a kick, then flew forward and knocked him away with a kick. However, he saw that Metkai immediately jumped back and then rushed over again.

"drink!"

To be able to become a chuunin, Metkai certainly has some real skills. He kicked the wind from his legs and directly attacked Natsume Yang's upper body.

When Xia Muyang went to deal with it, he suddenly fell upside down with his hands on the ground and his legs spiraling out. Xia Muyang was shocked and was forced to retreat.

"Konoha Tornado!"

To say who can use this trick most skillfully, it must be Metkai.

When he used this move, his legs were so strong that even Natsume Yang could put to shame, and Metkai forced him back again.

"It's Metkai after all, awesome!"

Natsume Yang stopped his body, facing Metkai who was charging towards him again, and kicked him against him, using his powerful force to knock him back.

Then, with a short step, he turned around and kicked Metkay in the chin. Then, he disappeared in a flash, then appeared behind Metkay, kicked out, and then dodged to another person. place, continue to attack.

This cycle goes on and on, and the entire sky is covered with Natsume Yang's traces, and Metkai has no power to fight back.

"Bang!"

Of course, because the opponent was Metkai, Natsume Yang stopped the last blow and hit him hard, sending him flying away.

"ha!"

"ha!"

"ha!"

"As expected of Natsume Yang, you are really powerful. It seems that you won't be your opponent using ordinary physical skills. So, I have no choice but to use this move!"

Metkai got up from the ground, panting, then squatted down and untied the restraints on his face.

"bring it on!"

There was a trace of expectation in Natsume Yang's eyes. In the world of Naruto, the fastest physically is Hachimon Kai. He wanted to know how strong the young Kai in front of him would be.
