I know this is definitely a power fantasy and Lin Moyu never really struggles, but having full immunity to all negative status effects seems like it's bit too much. Now the author can't even threaten the MC with some debuff that makes him have to temporarily struggle, or make him have to figure out the optimal time to use the Blessing of Light given its long cooldown... Now he's just immune.
Now the only thing that can reasonably threaten him is just overwhelming power.
