Mayfly

This infiltration technique is characteristic of Zetsu. It allows him to merge his body with the ground and flora and travel at very high speeds; however, it is noted not to be as fast as teleportation techniques. His insectivorous plant-like shell has the ability to merge with the ground, because it is tinged with his chakra. Then, using the underground network of organic matter, consisting of things like plant roots and water veins, he can travel everywhere with high speed. Using this technique he can conceal himself in trees and even sand. Once merged, his presence is completely concealed, making it almost impossible to detect him, even by sensory type ninja like Karin. This makes this technique perfect for close range spying.

Hachiro Learned this by using his wood release ot merge with the ground however thing can only be done in area where lands vegetation is right for example In Sunagakure this Technique is useless to him as there is little surrounding vegation. and he can only it for escaping and traveling purposes
