This is a world shrouded by a black sun.
On the day the apocalypse arrived, the sun in the sky was suddenly eclipsed. But once it had turned completely black, nearly all electronic devices soon stopped working, plunging the entire world into darkness.
After the eclipse, the sun never returned to normal. It remained black.
Then black rain began to fall from the sky.
Creatures touched by the black rain were infected by something like a virus, gradually turning into zombie monsters.
Humans... turned into zombies too, but a small number were different and didn't mutate.
And among those few, an even smaller number not only avoided mutation, but awakened powers.
They gained abilities such as fire, lightning, ice, and superhuman strength...
When Chen Yun woke up, he discovered that he had transmigrated into the apocalypse and awakened a very unusual ability: opening treasure chests.
The contents of each chest were random. If you could think of it, it could come out of a chest.
Hey! Isn't this just opening mystery boxes?!
(This story has a steady pace. The protagonist won't immediately become invincible and crush everything. He grows stronger gradually, and he's no self-sacrificing saint, but a fully fleshed-out character.)
It's not too much to ask for a positive review, is it? [Learned something]
That's outrageous, absolutely outrageous!
It's okay to repay a debt of gratitude, but you can't bring along a burden.
The quality is very good!
