I have an Apocalypse City - Chapter 360 - : Why Didn’t You Say So Earlier

I was reincarnated into another world, and I’ve brought the Horadric Cube from Diablo II with me.
Being a knight is cool and all, but being a wizard is pretty neat as well.
So, which one will it be?

In a world where dungeons were an essential part of it, Rein was trying to conquer as many as possible. They were the key to gain powers in the fastest possible way. So, to reach his full potential and to become the strongest, he became a great dungeon conqueror.With his trusty friends and lovers, he was definitely going to reach the peak alongside everyone. Join Rein and see how he went from strong to stronger and then the strongest.__________________1. The harem would not be too large(I'm not sure how many but probably just 4-5 main and few other here and there). All the girls would be getting their time and story.2. The story is starting when the MC is in the middle of his growth stage and not at the very beginning. But his beginning will be mentioned in the story in some form.3. I don't think I need to mention this, but obviously it will not have any NTR, rape or that kind of stuff. It is actually quite a wholesome story focusing mainly on adventure, action and bit of romance and slice of life.

Suddenly, a huge earthquake occurred all around the globe, throwing everyone into a desolate world.

The humans of the new world were primitive. They lived their lives facing all sorts of dangers every day, from hurricanes to attacks from huge beasts.

The humans that were brought to this world all received a totem and an egg.

Placing the totem on a certain land would turn the place into the person’s new tribe. Everyone could expand their tribes according to their strengths.

The eggs contained various beasts that would grow into humans’ most loyal companions. Humans would have to struggle to live in the desolate world with their companions and protect their own lands.

Just as Ye Chen was about to hatch his egg, he noticed he could read hidden hints.

[Monster Egg: Place a drop of blood to hatch.]

[Hidden Hint: Hatching the egg now will reward you with a Rank E Mutated Beast, Spiny Turtle.]

[Hidden Hint: Hatching the egg in 1 minute will reward you with a Rank D Mutated Beast, Dangkang.]

…

[Monster Egg: Place a drop of blood to hatch.]

[Hidden Hint: Hatching the egg now will reward you with a Rank E Mutated Beast, Yellow Horse.]

[Hidden Hint: Hatching the egg in 30 seconds will reward you with a Rank C Mutated Beast, Tiger Fish.]

[Hidden Hint: Hatching the egg in 60 seconds will reward you with a Rank SSSSS Mutated Beast, Immortal Phoenix.]

…

A few years had passed since then. Ye Chen led a group of Rank SSSSS Mutated Beasts and said confidently, “My success is the result of my hard work!”
