Traveling Through Another World, You Told Me That the Secret Realm Is the Earth?

Chen Xuchuan died accidentally while saving others and traveled to another world. Ten thousand secret keys suddenly appeared in another world. Those who hold the secret key can enter the secret realm, obtain supernatural powers, become a trickster, and open the curtain of turmoil in the inner and outer cities of other worlds. Chen Xuchuan, who traveled to the outer city of the Twelfth City, was on the verge of death and entered the secret realm, stunned. The secret realm is actually the earth? ! From then on, Chen Xuchuan in the secret realm often meditated. "I named this artifact the Heaven-shattering Hammer!" Chen Xuchuan looked at the big man in front of him waving a barbell with only one plate attached and was thinking. "Haha, my Divine Sword of Light, which sounds the spell of the ancient gods and exudes divine power, is a legendary treasure." Chen Xuchuan looked at the man in front of him, holding a plastic toy lightsaber, and played the BGM of "Daddy's father's name, what's his father's name, grandpa's father's name, grandpa," and fell into deep thought again. In the secret classroom, when the headless beast was spreading out its tentacles and preparing to pierce all the conspirators, Chen Xuchuan slowly stepped forward and wrote an X=3.
