I! Zhang Ziyu, a researcher full of dreams, became a time traveler and led me to study and traveled to this dangerous world. PS: It didn't seem dangerous. A large number of monsters died with just a wave of my hand. I was stunned. Am I invincible? But people here can escape to the sky and the earth. I seem to only be able to run...
