Cast Out by My Sect from the Start, I Turn Around and Become Invincible

Cheng Feng transmigrated into the body of Lu Xuan, a holy son in the world of immortal cultivation. Lu Xuan was the eldest son of the Lu family, a prominent clan in the Chishui Dynasty. Both his parents were powerful figures, and his maternal grandfather was the head of a sect. By all rights, Lu Xuan should have grown up with every advantage. Instead, he was sent to the Western Regions shortly after birth and vanished without a trace. At the age of three, he was taken in by the head of the Tianxuan Sect and brought back to the sect, where he became its holy son. Ten years ago, hoping to obtain more cultivation resources, Lu Xuan entered a sect tournament and suffered a crushing defeat. To keep the sect from being swallowed up, the ten-year-old Lu Xuan crippled his own cultivation and entered the forbidden Abyssal Depths, creating an opportunity for the sect to grow stronger. But when Lu Xuan was lucky enough to escape the forbidden zone and return to the sect, he discovered that without his cultivation, he was treated worse than a dog. His two closest senior sisters joined forces with his junior brother to torment and abuse him, trying to force him to give up his position as holy son. After awakening an Invincible System, Lu Xuan left the sect without hesitation. Just after he left the Tianxuan Sect, his family found him. He had hoped to join the family and enjoy his parents' love, but even without a trace of spiritual power, he was still bullied by his relatives. His father showed no love, his mother offered no protection, his younger siblings showed no respect, and they even wanted to kill their own eldest brother for fear he might threaten their position. With no other choice, he severed ties with the family and left... But who could have guessed that this seemingly powerless good-for-nothing was actually a mighty figure unrivaled in the world of immortal cultivation? The Tianxuan Sect was destroyed soon after Lu Xuan left, and the Lu family also came to their senses after his departure...
