Monsters Invade, You Say Simply Send Emperor Huang?

This is a world full of monsters! Chen Lan traveled through time and activated the summoning system, which can summon characters from all over the world! At the beginning, his city was attacked by monsters and faced a critical moment of death! He drew the strongest character in One Punch Man - Saitama! Transform into Saitama and beat the monster into blood mist with one punch! Not only that, you can also summon Emperor Man, Tiga, Transformers, Gundam, and Monkey King! "Monster? What's so scary about this?" … Some years later. The wormhole opened, and countless alien races and monsters descended on Blue Star. And you, summon the five-clawed divine dragon, stand tall with its head, and behind you are the armies of all realms. Emperor Huang Tian stood on the left, and Emperor Ye Tian stood on the right. Behind him are Emperor Man, Tiga, Monkey King, Godzilla and other super powerful combatants. When the aliens invaded and saw such a huge lineup, they were immediately frightened and cried. "No, isn't this Blue Star judged to be the most rubbish? Why are there so many horrors?" Chen Lan smiled calmly. "I'm sorry, because I am the summoner." "Monsters? Aliens? You send people as you please, I'll just send them here."
