American Comics: The Strongest Gu Master, Killing Through The Multi-Universe

Travel through the world of American comics and become the owner of a poisonous pet shop in Hell’s Kitchen.

One day, I received a system reward called Gu from a fantasy novel in my previous life.

Dali Gu: Watch me blow up the multi-universe with one punch!

Iron Skin Gu: Defend against any physical attack, even mushroom eggs will not do any damage.

Lightning Gu: Even if The Flash comes, he only deserves to be left behind to eat ashes.

Space Gu: Can break the multi-universe space and travel freely.

…

HYDRA? Purple sweet potato essence?

Dormammu? Mephisto?

The first firmament? Oaa, God?

There is nothing that cannot be solved by one Gu. If there is, then add a few more.
