Ye Shao went to a different world with nothing, just a broken book and a strange game system. There are all kinds of strange and weird mythical beasts in that world, but Ye Sheng's broken book also has many mythical beasts. It turns out to be the Book of Mountains and Seas... Summon them one by one. At most, they can be tough. If you can't beat them, they will fight in a group. Others are even more strange: He is obviously a good-for-nothing young master, but not only does his temperament change drastically, but he also has his own mythical beasts and birds tamed by him?
