Summoner of the Pirate World

How can a weakling with no strength survive in the world of highly skilled pirates? The answer: "Summon!" Whether it is Ip Man, the great master: "I want to fight ten!" It was Emperor Kai next door: "Eight Gate Dunjia, open!" Even those fighting people who turn into gorillas when they see the full moon: "Oh, garbage!" They can show up whenever I want. I'm weak, but my summons are strong? I'm also helpless, but I just like the way you try to beat me but can't. Let me see which master can be unlocked today... This is it!
