The upgrade system of all realms starts from conquering Naruto

"Akai, your father is a great ninja and a real hero in my heart!" Natsume Yang came to Metkai and patted his shoulder.

"Thank you!" Metkai sobbed, wiping his tears.

"Perhaps he was not conspicuous at all before, but that day, he blossomed into what he considered to be the most dazzling moment in his life. He must be proud!"

"Cheer up, Akai! Life is a long road. If you want to avoid things like this from happening again, then work hard to become stronger! I think Uncle Mattday doesn't want you to be so decadent!"

"Metkai, youth has no limits, become stronger until you can protect all the people you want to protect, and become the most reliable man in the hearts of your companions!"

"Don't forget, Metkai, you are a genius that I, Xia Muyang, recognize. I have been waiting for the day when you challenge me!" Xia Muyang sat cross-legged on the ground and said slowly while looking ahead.

"I'm so grateful!" Metkai sobbed and covered his tears.

"Then I'll leave first!" After saying that, Xia Muyang stood up and left.

Natsume Yang's house.

"Dong dong dong!" The door of Xia Muyang's house suddenly rang, making Xia Muyang unable to get up. He was also curious about who would come at this time.

"Who is it!" After Natsume Yang opened the door, he saw Harano Lin, Kakashi, and Uchiha Obito standing outside the house, which made Natsume Yang a little surprised.

"Come in and talk!" Xia Muyang invited the three people in, and then asked: "What's wrong, is there something wrong!"

Looking at Yuan Yelin in front of him, Xia Muyang couldn't help but frown slightly. He always felt that Yuan Yelin's aura became a little different.

"Thank you for saving us that day!" Yuan Yelin glanced at the other people, saw that they all looked embarrassed, lowered her head slightly, and whispered.

"That's right. I feel a little embarrassed when you say that!" Xia Muyang smiled and scratched his head, looking shy.

"Wait! Harano Lin... Kirigakure Village... The Third Ninja War... Could it be!!"

Xia Muyang suddenly seemed to have thought of something, and couldn't help but swallow, and his face became a little solemn.

If he remembered correctly, there should be a plot in this period in the original work: Kirigakure captured Harano Rin, sealed the three tails in her body, and asked her to bring the three tails into the Leaf Village.

Then the three tails were summoned in Konoha, and while Konoha was in civil strife, Kirigakure soldiers broke into Konoha and won the victory.

"If that's really the case, it would be really troublesome!"

"To be on the safe side, it's better to do some detection!" Xia Muyang looked hard and made up his mind!

Now that he has broken through the shadow level and mastered the Bagua seal, he can still fight even if he encounters the three tails.

"Kakashi, Obito Uchiha, can I ask you two a question?"

Natsume Yang spoke with a slightly solemn tone, causing Kakashi and the other three to look at him.

"What's wrong? What happened?" Yuan Yelin said, with a puzzled expression on her face.

"When you were rescuing Harano Lin, did you find anything wrong with her?" Natsume Yang ignored Harano Lin for the time being and stared at Kakashi and asked.

"No, what's wrong? When we went to rescue Lin, she was fine!"

Kakashi replied simply, and Uchiha Obito beside him also nodded, and then looked at Natsume Yang, with the same puzzled face, wondering why Natsume Yang suddenly became so serious.
