A hundredfold return, I'm lying flat in Konoha.

Yagyu traveled to Konoha and became an ordinary member of the Moonlight Clan, living in the same era as Naruto and Sasuke.

With average talent and a family with limited potential, how can one break through this predicament?

Fortunately, there's a 100x return system, and I'm bound to Uchiha Sasuke.

The stronger Sasuke becomes, the stronger I become!

[Ding! Your bound target has increased their chakra by 0.001 cards, and you have received a 100x return of 0.1 cards of chakra increase!]

[Ding! Your bound target's Three Bodies Technique proficiency is 1. You receive a 100x return, proficiency level 100!]
