Huh? Wait what? What's happening

A slight recap, they are currently in a BL world with the OG MC a Mary Sue (Wenliu guy) ending up being reborn, got almost erased by Main System, Wang Yi saves him with a gourd bottle item preserving his soul, the white cat's objective is unknown for now, the ML is that Swordmaster guy with MC as his disciple and realised his true identity, some past background was given about him and currently they have to continue the original plot while avoiding the watch of the Main System.
Also, Wang Yi releases the OG MC later, but his personality changed and didn't go after MC the 2nd time. I'm randomly guessing that the red haired guy could be Wang's friend (the guy who called him air-conditioner)
Due to the existence of the system, MC & ML had to lose their memories, but MC remembered them first as the OG MC was mistakenly reborn which wasn't supposed to happen, so Cat brought them back. ML is still in recovery mode and only recalls slightly.
Wait you're too fast? Or was it short
