FGO: the Master of Time Travel

Mengxin would like to ask, I pulled out a big-breasted sister holding a knife. Is it useful? This is a story about a weak male protagonist who takes the FGO system and travels through various worlds in the second dimension. Each world summons a new follower, of course all female characters~ The same cool and invincible YY stories, no abuse of the protagonist, no strategy for the original heroine, the harem is just drawn female Servants This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
