After Cultivating Immortals and Being Reborn on Earth, They Want to Change the World

I think a black hole is not the product of a supernova explosion. It should be the meeting of two or more massive celestial bodies. The fusion reaction of devouring each other exceeds the supernova limit. The density continues to increase with the reaction. When it reaches a critical value, gravity can capture light, and it can be called a black hole. During the transition period, it will definitely become a super neutron star. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
