In Konoha: Have You Ever Seen the Village at 4 A.M.?

Feng Chen transmigrates into the Hokage world and activates a Self-Discipline System. Completing System missions earns him temporary rewards.

There is only one kind of reward: unlimited chakra and stamina for a limited time. How long it lasts depends on the difficulty of the mission.

Often, missions require him not only to discipline himself, but to get other people to do the same...

He gets the Third Hokage to quit smoking, stops Might Guy from overtraining, keeps Kakashi from reading novels, and gets Choji to lose weight...

What's even more interesting is that the System missions arrive at random and cannot be stopped.

Just as the Chunin Ninja Exams begin, Feng Chen runs into Gaara, and a System mission kicks off.

Gaara, who had been unbeatable in the exam arena, is forcibly dragged off by Feng Chen. The mission is to take a bath together, and they have to make sure there's not a single grain of sand on either of them!!
