They all call me Great Master - Chapter 5 - 3 Omnivorous!

In the Interstellar era where the strong are king, soft and cute species are almost all extinct.

Tu Mianmian, who crossed over, was given a ruthless Duke husband, a husband who could destroy Mechas in minutes.

As a lop-eared rabbit who had just refined his human shape, he felt weak, pitiful and helpless.

So, he resolutely ran into the entertainment circle, relying on his sky-defying appearance to garner large amounts of fans from interstellar society, including his own gong/husband.

It was night, and the Duke who was going to improve the relationship between husband and wife walked to the door and saw a fluffy lop-eared rabbit lying on the sofa…

When Tu Mianmian found himself sleeping beside his gong with his rabbit body stretched out, he scared himself. Sitting up in shock and dazed, he unconsciously stomped the Duke’s mouth. Shivering, he retracted his rabbit paw, but was caught by his gong with a cold face.

Tu Mianmian: …I, I, I am willing to cut off this rabbit’s paw!

Before he could finish speaking, the iron-blooded Lord Duke approached his mouth at the speed of light: Chuu~~ ( ˘ ³ ˘)♥

Reborn as a Gotham minion and strayed into an evil organization, his heart is bright but he has fallen into darkness step by step. The whole world and even countless worlds are convincing the good guy Mason that it is obviously more promising to become a super villain in this era of disaster.

But Mason didn’t think it was easy to convince himself, so let’s do something simple.

How about we try to bring this dark and chaotic era back on track?

besides!

Batman and the heroes of the Justice League, when are you fucking going to do it? If I don’t close the net, I will go undercover and become the evil boss!
