He didn't want to die, but he was powerless. On April 1, Jing Chu received a letter, a black letter that looked very evil. The content of the letter was as follows: Congratulations on receiving a registered ghost letter. In order to study the adaptability of carbon-based organisms in different time and space... Bara Bala signed: All the staff of Pamiwa Carbon-based Biological Research Group, Jing Chu traveled through time... It was originally just a joke, but I didn't expect it to come true. April Fool's Day jokes can't be made casually.
