Lin Feng is a brilliant engineer who builds a super-powered robot. Hoping to make it stronger, he recovers an ancient relic called the Eye of the Ancestral Dragon from the depths of an abyss. While he is channeling its energy into the robot, the relic's divine power flares up unexpectedly and opens a rift through time and space. He is reborn on an ancient continent where martial arts are everything. His old memories are sealed away, and he awakens only a healing-type martial soul, so others scorn him and his fiancee calls off their engagement. When her clan tries to kill him, his memories of the Dragon Eye return, and he learns that its power has merged with his robot. With the machine's help, he sets out to master that power and become strong in this action fantasy ONA.
