MTL - After He Swapped Bodies With His Pregnant Wife - Chapter 6

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?

Utsuro no Hako to Zero no Maria, or The Empty Box and The Zeroth Maria, tells the sinister story of Kazuki Hoshino, who is almost madly attached to his everyday life, and his antagonist Aya Otonashi, who suddenly transfers into his class—for the 13,118th time.

“Take me in, I’ll do anything you want me to!”

In her previous life, Lu Man is sent to prison after being framed by her step-sister and an asshole. After being released from prison, the only thing that greets her is her mother’s tombstone.

The moment she opens her eyes again, she finds herself back on the very day she was framed. Resolutely jumping out the window and climbing next door, she seeks refuge from the man occupying the room there. But who would have guessed that the man is the brilliant hunk she has always admired from afar in her past life?

She vows to rub her eyes clean and be more discerning of people. She wants to make everyone who owed her in the past to pay her back!

“Young Master Han, can you let me hug your other arm too?”
“Actually, I have one more, do you want it?”
