I Am Bound to Two Chat Groups After Death

Li You never imagined that after his death, he would be bound to two chat groups at the same time.
On one side is a comprehensive chat group where big bosses gather.
On the other side is the chat group of the dead in the afterlife world.
Joan of Arc at the stake, Himeko who fell into the imaginary space, the female swordsman who was swallowed by a beluga whale, Miss Froststar who lost her body temperature on Christmas Eve, Yanzhu who died heroically, and Jotaro Kujo who died to protect her daughter ...
In order to be able to return to the world of the living, as a cute newcomer, Li You asks the bosses for advice every day in another comprehensive chat group, and occasionally helps Miss Shuangxing and Aunt Jizi to ask some strange questions. .
For example, "[-] anatomical methods of the undead", "postpartum care of beluga whales", "how the undead are made", "reconstruction of bones and souls", "how to reverse time"...
Over time, in the comprehensive chat group on the other side, he was given various titles——
"The Demon King of Immortality", "The Creator of the Undead Natural Disaster", "The Nameless Disaster", "The Retrograde in the Long River of Time"...
"??? I'm really just a newbie!"
