😋I recommend the following doomsday novels to you: 1. I Am a Defensive Tower: A combination of Doomsday and tower defense. The protagonist has the ability to build a defensive line and launch a strange and intense battle. 2. <Star Beast King>: After the soul imprint of the King of Summoning awakens, the star beasts of the entire Universe Federation begin to awaken, revealing the secrets of the universe. The author has five other completed works! 3. "Cool in the Doomsday": The protagonist who transmigrated to the Doomsday has a system that requires pleasure, and begins a happy and adventurous journey. The novels above all had elements of doomsday summoning, so they had different gameplay and fun. I hope you like my recommendation. If you need anything else, feel free to tell me ~
