Is the latest and only 7th Generation Nano Machine that is successfully made and was injected to Cheon Yeo Woon by his descendant from the distant future during the start of the story.
After being held in disdain and having his life put in danger, an orphan from the Demonic Cult, Cheon Yeo-Woon, has an unexpected visit from his descendant from the future who inserts a nano machine into Cheon Yeo-Woon’s body, which drastically changes Cheon Yeo-Woon’s life after its activation. The story of Cheon Yeo-Woon’s journey of bypassing the Demonic Cult and rising to become the best martial artist has just begun.
The Nano Machine injected at Cheon Yeo Woon is comprised of about 6.5 billion nanobots that are deployed throughout the body and are centrally connected to the user’s brain. It isn’t detectable due to the materials used as its composition and can’t leave the user’s body and are ejected upon complete death of the user.
