Sage Transformation was, in other words, Senjutsu.
Ninjutsu used chakra created from one's own "spiritual energy" and "physical energy," making it an internal energy.
Senjutsu, however, required external "natural energy," mixing all three energies to create the more powerful senjutsu chakra!
"Although I can practice ninjutsu in the Training Ground, Senjutsu is completely out of the question." Uchiha Naruto paced back and forth in his room, looking thoughtful.
"Is it because there's no natural energy in the Training Ground?"
Natural energy existed between the earth and the atmosphere. The Training Ground's simulated environments were not real, after all.
After leaving the Training Ground, Uchiha Naruto began to vaguely sense something in the air.
Fortunately, Earth had natural energy too. Otherwise, Sage Transformation would have been completely unusable.
But with this tiny amount of natural energy, never mind Sage Transformation-even trying to enter Sage Mode would take twice the effort for half the results.
His LV1 Sage Transformation barely qualified as beginner level.
"Tokyo is a bustling steel jungle steeped in luxury and excess, so there must be less natural energy here. Perhaps it would be easier to sense in remote mountains and ancient forests."
The concept of natural energy felt a little like the spiritual energy of heaven and earth that frequently appeared in cultivation novels.
The cultivators in those novels secluded themselves in mountain forests and withdrew from the world because the mortal world lacked spiritual energy. Living in a city for a long time brought cultivation every disadvantage and no benefit.
"When it comes to beautiful natural surroundings and lush vegetation in Tokyo, Ueno Park and Yoyogi Park are definitely the places."
Although Ueno Park was the largest, it was in Taito Ward. Yoyogi Park in Shibuya Ward was closer.
Adjacent to NHK Television and Meiji Shrine, Yoyogi
