At Lv999, I Built a Palace of All Realms

Han Xiao traveled to the world of demons and after a long period of hard work, he became a top level 999 demon. Unexpectedly, the system accidentally activated its final form at this time, the strongest system in all worlds. From then on, a palace of all realms appeared in the world of demon gods. "Why is Ace, who just disappeared for a while, so powerful that even Akainu was beaten?" Everyone on the battlefield was stunned. "Why did Stark develop the final form of the Iron Suit so quickly, and why does he know everything?" Justin Hammer couldn't believe it. "Auntie, why don't you love me anymore? Who is that person named Han Xiao?" Yang Guo was heartbroken. … "Originally I just wanted to be a super demon who ate and waited for death, but I didn't expect that I accidentally turned into the lord of all realms." Han Xiao looked at the people from all realms who surrendered in front of him. He felt that being invincible was really lonely! This novel and its characters are purely fictitious.
