The so-called secret pills left by the Uchiha ancestors!
This was just a batch of pills Wang Ming casually refined while treating Setsuna's body.
The Uchiha Clan had two summoning scrolls: ninja crows and ninja cats.
Ninja crows leaned more towards combat, which was the summoning animal Itachi Uchiha used.
Ninja cats leaned more towards intelligence, so Wang Ming had the ninja cats bring him a vast amount of medicinal herbs to refine this pile of unranked pills.
Raising the bloodline strength of the entire Uchiha Clan!
Naturally, this was not to save them, but to make the game a lot more fun.
Because they were custom-built to fit the Uchiha physical constitution, if these pills were given to other clans to eat, it would easily lead to mental disorder and madness.
As for boosting chakra, physical reaction speed, and healing hidden injuries, those were merely side effects.
The entire ninja world was monitored by the chakra of the Sage of Six Paths. If Wang Ming jumped out himself and used sheer overwhelming force against Hiruzen and the others, he would probably get checked by a max-level veteran before even stepping out of the newbie village.
He needed to guard against the Six Paths checking the water meter, which was why he chose the Uchiha as his starting faction.
The will of the Uchiha could not be directly controlled and modified by the Six Paths, so it was understandable if they did things outside of his script.
Otherwise, why would Black Zetsu only target Indra's lineage for deception, and never lay a hand on Ashura's line?
It was simply because that stubborn blockhead could not be moved at all!
Even if one spent painstaking effort to brainwash and awaken them, they would turn around and be influenced by Ashura's will,
