MTL - There Is Chef Yu In The Entertainment Circle - Chapter 54

A 40-year-old man suddenly dies and is reincarnated in a world devastated by zombies—but instead of becoming a hero or a survivor, he wakes up as a zombie girl.

Xiao Luo and his girlfriend had been in love with each other for four years when she proposed a break up. Because of this, Xiao Luo sped his car in the night and ended up in a car accident. But it was a blessing in disguise as he unexpectedly fused with a high tech system that originated from a universe hundreds of billions of light years away. From this moment on, the entire world started to run amok.....

The formless ancient world was infested with despicable demons. They hunted and feasted on mankind, keeping the human civilization constantly in a weak and suppressed state.

During the first known year, a magical mountain descended into the world from the realm of the Gods. Carved on this enormous mountain was a message: ‘Heaven Prevails’…

After the Grand Descent, a name that was given to the descending of the mountain, the Three Great Sages made their ways to Mystic Mountain where they learned to harvest what we now call magic, establishing the Mystic Cults and eighty-one sacred shrines to help aid mankind with the cult’s mystic powers against the eternal fight to the death with demons.
