MTL - Magic Chef of Ice and Fire - Chapter 237 Military division of the four-nation coalition army (below)

Lu Ze transmigrated to the interstellar era two thousand years later.
The previous owner of this body had lovey-dovey parents and a cute little sister. Although his cultivation talent was ordinary, his life was fulfilling. It could be said to be a dream start. Lu Ze was very happy.
However, as soon as he slept, he came to a strange dimension.
He almost got taken out trying to fight an one meter tall huge white rabbit. After making the arduous kill, Lu Ze found that things didn’t seem to be so simple.
After killing prey in this dimension, he could get little orbs that could be used for cultivation.
This was going to make him an eternal jungler.
But he seemed to be able to hope for domination of the cosmos and invincibility?

This is the story of a boy who lived a secluded life in the mountains, tending his farm, rearing his fish, and dreaming his dreams. Eh? Did I suddenly conquer all worlds and become the big boss? Or am I still in a dream?

When other people experience a body transformation, it is inevitably either male to female or female to male.

Me? I wake up to find myself transformed into two different bodies.

Both a male body and a female body, one conscience operating two bodies, all sorts of embarrassing moments.

Walking together normally makes other people think that I am sweethearts with my other-self, such sadness.

Also, the entire business of a hero rescuing the beautiful maiden, I call Bull.

I get slashed by a sword and my female body gets abducted, and he wants me to thank him?!?! Can it be less of a tragedy?
