Everyone's Challenge: I'm Invincible with the Simulator

Qin Tian traveled to a world where spiritual energy was revived and seven or eight worlds merged. In this world, there are constant wars between various countries and even various races. Later, Qin Tian learned that everyone in this world can enter the Tiandao Tower and choose different majors when they reach adulthood. Someone broke into the command system, obtained a war artifact, and dominated the battlefield to scold Fang Qiu. Someone clears the knight series, gets a dragon egg, becomes a dragon knight and wreaks havoc on the battlefield, forming an army with one man. There are also people who have passed the mage system and obtained the godhead, changing the world and shaking the earth with a wave of their hands. And Qin Tian got a simulator to break through the level. If others failed to break through the level once, they had to wait a day before continuing, but Qin Tianque could simulate it a hundred times in the simulator. This is good, most people specialize in one department, and minoring in one department at most is already very tiring. And Qin Tian said, I want them all.
