Training in Sage Mode

"This child is truly remarkable."

Sage Fukasaku marveled inwardly.

No one had sensed natural energy so quickly except the man known as the Sage of Six Paths a thousand years ago.

Soon, Kazan tried drawing in the natural energy in the air.

As a sacred land of the shinobi world, Mount Myōboku had the richest natural energy, hanging thick and viscous in the air.

Kazan naturally understood the dangers of senjutsu training.

"If you can't control natural energy properly, you'll turn into a toad," he warned Kazan. "You need to keep the natural energy you absorb in balance
