Global Summons: Link to the Underworld at the Beginning

In the 333rd year of the Blue Star Calendar, the sun suddenly undergoes a sudden change. All animals and plants that are illuminated will change their temperaments, become extremely cruel, and slaughter humans crazily. However, there are also some human beings who will undergo mutations after being illuminated by the sun. These people are called summoners, and they will summon various mythical characters to resist these mutated beasts. Henry Zhang, who traveled through time, accidentally connected to the underworld and could summon all the great gods in the underworld to fight for him. I'm a newbie. I really can't write an introduction. Anyway, it's just fun. Please support me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
