I Was in Tiga, and I Took Melba at the Beginning.

Li Yunfei traveled to the world of Ultraman Tiga and had a monster collection system. As long as they are monsters or cosmic beings that have been killed by themselves, they can all be summoned. But when he looked at the two giant beasts in the distance that were using their skills to clear the pyramid, and found that the system didn't even provide an initial monster, he couldn't help but raise his head and sigh: "What a cheat!"
