Zhang Ze travels to a parallel world, where people rely on the magic domain to fight monsters and become stronger to resist the invasion of monsters in the magic cave.

She entered the Demon Realm for her younger sister Zhang Ze, named Luo Sha, but accidentally activated the strongest SSS-level talent summoning technique!

Killing monsters can be summoned, the higher the level of summoning, the more monsters can be summoned, and they can be upgraded, it is simply against the sky!

In the Demon Realm, when other adventurers form a team of hundreds or even thousands of people to attack the boss, Zhang Ze has already led his army of summoned monsters to crush them all the way!

In reality, when countries were still worrying about dealing with high-level monsters, Zhang Ze singled out hundreds of high-level monsters, shocking the whole world!

“Who the hell is Rakshasa? Breaking the record of human beings exploring the Demon Realm all the way, it’s about to break through a hundred floors!”
