Fantasy: Start with the Extreme System and Push All the Way

【Shuangwen, invincible】 In his previous life, Jiang Xuan, a mercenary, was betrayed and reborn into a sycophant in a fantasy world.

Jiang Xuan traveled through time and space, and when facing the life and death of his family, he activated the Invincible Extreme System. It is extremely rare for other martial arts practitioners to reach the extreme in a certain realm. They are called peerless geniuses and have supreme qualifications.

"Haha, in front of me, Jiang Xuan, who dares to call myself a genius and be undefeated!" I am the unrivaled emperor of the ultimate realm!
