A brief description of the manhua After Signing In For 30 Days, I Can Annihilate Stars:
The invasion of otherworldly deities.
10,000 “liberators” have been chosen to enter a hidden world, where the bloodthirsty battles against demonic beasts are streamed live for the whole world to see.
Chu Mo: What the fuck?! I’m useless on the side of these powerful people! It’s a crime to put a normal person to fight a demonic beast!
“Active registration system.”
Registration Reward – Day 1: The power of a 1000 year old demonic beast.
Registration Reward – Day 2: The legendary God of War experience in combat.
….

W-what? Will I become like Saitama with the 30th day reward?!”
