Equivalent Exchange: Invincible Starting from the Adventurer

"Who is coming?" "Ahem..." Gu Zhong cleared his throat, "The wall of immortality, the tracker of Wanlin, the holy healer and blade of the void, the king of elements, the incarnation of the god of war... Which one do you want to hear?" "... What profession did you study?" "I've learned everything." Gu Zhong said. A scale is engraved on the front of the copper coin, and a line of ancient characters is engraved on the back. Gu Zhong called a copper coin next to him after time travel [Equal Value Exchange] - Gu Zhong can make an exchange of equal value once a day. You can also change your career. Today he is the [Unbreakable Wall], guarded like an iron city, and cannot be broken by thousands of armies. Tomorrow he will be the [Ten Thousand Forest Tracker], and everything in the forest will be invisible. The day after tomorrow, he can be the [King of Elements], and the elements of heaven and earth can move according to his thoughts. The day after tomorrow, he can be the [Blade of the Void], and no one knows where it is before taking action. Others can only choose one career in their lifetime, but Gu Zhong makes the exchange every day.
