Family Too Powerful, Forcing System to Darken and Upgrade

Chen Mu is reborn in the Great Cang world as the sole heir to the Heavenly Yuan Holy Ground. After failing the talent test with a low-tier spiritual root, he expects ridicule but instead receives encouragement from everyone. Back in his room, Chen Mu binds the Invincible Rise System, but refuses to activate it, forcing the system to continuously upgrade and automatically check in for a Saint-level divine weapon, the War God Sword. Meanwhile, his cousin brings him a sword case containing the God-Slaying Sword.
