I, the Strongest on the Surface, Am Being Targeted by All Races!

My name is Su Jiu, an ordinary high school student who accidentally traveled to a world where spiritual energy was revived. In this world, countless demons and monsters were born, and even a terrifying dark restricted area appeared. Just when humanity was in danger, I awakened the strongest system. Three years later, no monsters from the demon clan can be my opponent, and even the dark restricted area can be broken with a single poke. This scene was broadcast live by satellite. The dynasty called me the "strongest man on the face of the earth" and betrothed me to the first princess of the Yan Dynasty. Just when this news spread, the passage to all realms opened, and all races invaded the main world. Just when I was about to kill the enemy, a fox demon who claimed to be a princess suddenly said to me: "You must be the strongest man on the surface. You are very good. Come back with me and be my husband!" The title of the book is: Isn't it enough to be the strongest on the surface if you have hands? , These princesses are a little weird!
