I’m giving MC grace despite being a hater of weak ukes because if I were in his place as a regular citizen, I’d also cry or just kms. It’s easy to critique one’s weakness when you’re not the one experiencing it. But I do get your point, I wish he at least grows as a character and develop as the story progresses.
You BETTER read the Novel. MC learns to pull his own weight and even the whole team depends on him. They even said how it was MC who made them feel human. Imagine it's like Necromancer Survival, but a lot more difficult since MC & his team won't be coming out any sooner. Also, MC being a crybaby is only in the beginning. He will be able to increase his powers later on. Also, get his sweet revenge with his oen hands. An honest suggestion to not give up even if the initial chapters are slightly draggy, they will be important later.

This story would be better if uke grew a backbone instead of crying about everything.
