You were supposed to be tempering yourself, but instead you're spreading your roots and branches?

Ye Xuan was hit by a car and died while saving someone, then transmigrated to a fantasy world. He awakened an invincible system. As long as he completes tasks according to the system's requirements, he will receive extraordinary rewards.

"Ding, detected host completed task, rewarded host with max-level mastery in zither, chess, calligraphy, and painting!"

"Ding, detected host completed task, rewarded host with the destined magic treasure, the Three Generations Bronze Coffin!"

"Ding, detected host completed task, rewarded host with grand mastery in swordsmanship!"

"Ding..."

Years later, Ye Xuan became invincible under heaven thanks to the system. One day, an immortal descended to kill Ye Xuan, but was instantly crushed by Ye Xuan with a single finger. Only then did the world realize that the seemingly unassuming Ye Xuan had long been invincible across all heavens and myriad realms.
