Save Hydrangea at the beginning of the anime

Lin Xiao, who was developing feelings with his sister-in-law, traveled through time inexplicably.
He traveled to the world of hentai and started by saving the hydrangea that was being framed.
After rescuing people, the time traveler's essential golden finger - the system, arrived late.
As long as you intercept the evil male protagonists in the original drama, you can gain health points and various rewards.
As long as you intercept enough, longevity is not a dream.
In order to achieve immortality and to save those poor heroines, Lin Xiao then rushed on the road of intercepting.
A few years later, looking back, I realized that a group of beautiful women had gathered around me without me noticing.
Purple Palace Xia Ye: Lin Xiaojun, duel with me, the loser will...
Chiba Yuki: Onii-chan, Yuki still doesn’t understand this knowledge point. Can you help Yuki with some more lessons?
Akane Nanao: Lin Xiaojun, do you like this dress?
...
(PS: The male protagonist is wearing it, so you can eat it with confidence.)
