Taking Sasuke and Naruto as Disciples from the Start, I Return Their Abilities a Hundredfold

After transmigrating into the world of Naruto, he becomes a substitute teacher at the Ninja Academy from the start and awakens the Super God Disciple-Taking System:

The stronger his students become, the more power he gets in return, tenfold or even a hundredfold!

His student Uchiha Sasuke learns Chidori, and its power surges by 10,000%. He receives the S-rank Lightning Release technique, Myriad Birds Soaring to the Phoenix.

His student Uzumaki Naruto uses Nine-Tails chakra, and its power surges by 10,000%. He receives the Nine-Tails Sage Mode.

His student Uchiha Sasuke awakens the Sharingan, and its power surges by 10,000%. He successfully awakens the Mangekyo Sharingan.

His student Uzumaki Naruto successfully senses natural energy, and its power surges by 10,000%. He learns the Perfect Sage Body.

Years later, Chiba stands before Otsutsuki Kaguya, wielding a pair of Rinnegan and commanding a Susanoo hundreds of meters tall, clad in the Complete Ten-Tails.

He pushes up his glasses and addresses Sasuke, Naruto, and his many other disciples standing beside him:

"My disciples, I'll teach you this move just once."

"Have you ever seen a palm strike descend from the heavens?"
