Ultimate Martial Soul

Young Chen Feng's dantian is as hard as iron, making cultivation impossible. Only his loyal master refuses to abandon him, but when the master is killed by a powerful figure, Chen Feng loses all protection and faces relentless bullying. After faithfully guarding his master's grave for five years, he discovers the master has faked his death and uncovers the supreme dragon blood and a mysterious ancient cauldron left behind. From then on, Chen Feng rises against the heavens, embarking on a journey to find his master and become a powerful warrior.
