The only good thing about it is okay art and decent comedy.
Everything else is pointless. MC is a pathetic miserable coward who runs away from everything. The system bends over backwards to give him rewards for staying low-profile aka running away, doing nothing and in-universe decision somehow make sense. Characters don't really question him. There's no interesting choices made.
MC being a former cancer patient gets a second chance at life, you'd think he make something out of it but no he doesn't. He only cultivates alone, that's it.
I understand his motivations that he wanting to live a long life and trying to stay out of trouble, but closed cultivation 99% of time is not it.
The MC joins and becomes an inner disciple of a Sect with his great skills, joins a division that suits his motivations. Human relationships? Nope. Master-Disciple Relationship? Nope. Romance? Nope. Contribution to Sect? Nope. He gets a salary while leeching off of them. There's no give and take relationship, unlike other disciples who do something at least.
MC gets into a competition to get resources and a cave, drops off after getting into Top 3. Yeah it was funny seeing MC get to the top while pissing off the audience acting weak to stay low-profile but him escaping all the time is again not interesting.
Time-skips are also bullshit here. Time-skips are nothing rare in the cultivation worlds but it's used terribly. I don't see the point, he cultivates for getting a longer life, where he does nothing in his life. Remember the competition? He missed it because he was in closed cultivation so what does he do? We get another time-skip for 8 years so he can join it and get resources boo-hoo. It's just another convenience to see him grow stronger.
Onto the sect again, the disciples are getting attacked by fiends, they're increasing their offenses but MC is in closed cultivation whenever it happens. Later the sect is attacked by them, thousands die, disciples get injured. When the MC gets out and learns of it, he is visibly shaken and gets called by Master. She thinks he betrayed the sect and tells him to leave, ending the chapter in a cliffhanger. I finally thought he's going to facing consequences but in the next chapter lol nope. Actually it wasn't really much, he convinces Master he will stay in the sect, going to cultivate again, gets rewarded by her and the fucking system again.
At the beginning of series, MC escaped from Elder Iron's slave labor. MC ends up meeting him, gets so strong that Iron becomes his Junior. There's no reconciliation between them. MC holes up to cultivate again, Iron passes away in the middle of it. He reminisces how while was slaving the non-cultivators he still gave them a good life, he raised him up even after his parents ran away. In the end that moment still feels pointless because MC did nothing but cultivate.
Fiends make a plan to attack to destroy them once and for all. Time skips again baby. MC gets out find out they're getting attacked, one-shots all of the enemies and back to cultivation.
So yeah it's the same thing over and over again, MC is a coward who does nothing but cultivate, runs away from everything, only gets out to fight whenever bad guys attack which is convenient for him.
