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.
Nano Machine
In the past, Cheon Yeo-Woon’s life was stolen away from him by the Demonic Cult, and was later saved by a girl named Choong Eun-Ah. The Demonic Cult ruthlessly murdered Choong Eun-Ah and then used Cheon Yeo-Woon as the tool to create a drug called the “Prime Blood”. The Prime Blood can restore stamina to one’s body at an amazing rate.
Despite being an orphan, Cheon Yeo-Woon is born with superior martial arts talent which he then used to his advantage easily defeating over 100 opponents during his time in a specialized arena for entertainment only made for martial artists called Martial World (琉人武林). Born with the high self-confidence of his skills and talents, Nano Machine Cheon Yeo Woon gets pampered by the nurturing of people until one day when he easily defeats a man named Young Do who uses advanced tricks within their martial art fights -Heuk Beom Taekwondo technique (虎拳). After defeating Young Do, Cheon Yeo Woon meets Hwang Chi Yang who later becomes a roommate of Cheon Yeo Woon and shows interest in him because of his great talent.
Cheon Yeo Woon eventually challenged Hwang Chi Yang but lost against him. Although he lost, he gained good friends out of it and Cheon Yeo Woon's popularity and prestige soared high. Next, Cheon Yeo Woon challenged a powerful child mafia boss named Sunk Ju Gi (鮮樸九義). A fight broke out where Hwang Chi Yang, another powerful martial artist came to help out Cheon Yeo Woon with his moves but also lost. Tu Ja Kye and Hwang Chi Yang rescued Cheon Yeo Woon after they thought he was dead. After they left, he escaped with the aid of Ki Goo and takes shelter in his house (underground waterway).
While living together under one roof, Hwang Chi Yang expresses his affection for Joo Mi who is already dating the new star, Ji Sun-Woo who presents her with a ring but she rejects it. Dae Sung also announce that a big tournament will soon begin on Hanyang in which whoever wins gets a seat on the Grand Council along with 6 billion dollars as prize money and says this will be open to every martial artist alike from all over the world including Korean’s mean move gangs underworlds lead by cold blood devil men who are determined to win at any cost even having a fair fight is no longer an option for them.
Sun Woo originally plans to visit America more often and earn more fame but changes this idea because of guilt from separating from Joo Mi and therefore wants her to go as well while protecting her during these times before his departure because he safely kept Nano Machine her hidden so far away following an attack on him but Alisa asks him to stay saying she will protect Joo Mi following her instructions allowing him to go but during Dae Sung’s absence, her daughter has changed and used ill for some reason returning to Hanyang Headquarters despite his father's instruction because of strong curiosity now with a hint of attitude even towards his mother. Seeing this change, he gets furious realizing Hwang Chi Yang pry has erased some parts of memory after knowing the sword is slowly taking its toll on Joo Mi and at the same time accepts losing it as a price for gaining Jin Yu Myung.
The tournament begins with powerful headless beasts attacking worshipers followed by sudden improvements among several martial artists in due time who turns out to be Madame Alisa’s informants and the right-hand members leading Ji Sun-Woo’s group along with Ji Han Seok faction group led by President Shin younger brother who previously were part of Badger Korean Martial Arts Tournament Circle Kim Han Soo (Park Joong Min), comparing these elite competitors, cause more worry at HP headquarters because they are well prepared but other gun rankings are not ready yet which becomes a very serious concern among especially military department because if survivors used guns instead of deadly hands that day many lives could've been spared. At several assassination attempts on fighters participating in the tournament including Ji Sun Woo respectively they are not returned unscathed while heavily equipped operation force dead bodies from extermination have been discovered near mountains each over 16-19 years old. Soo Gook is notified a temporary lead figure from the military department to replace Director Kim and the command martial arts tournament will commence shortly after Colonel Do Sam Seok and his fellow peers sneak the guns caught from underground factories from the military onto participating fighters’ position without telling anyone until he has been discovered by tactically gifted Captain Han Sol but risked getting killed when he, instead of fleeing for his life chooses to arm himself and hide behind rocks recklessly with last chance until luckily team leaders stop them both.
The next day all competitors were made on the death list including less trained Shin Ji Woo while walking around friendly countries they encountered horrendous mutants including those who ate the boss’s friend in the car dealership and since then no one could stay unaware of possible annihilation at flesh-eating beasts anywhere around a metropolitan city.
Refusing to give up, if pieces of evidence exposed that guns producer Nam Da Jung implanted mechanical chips in human body parts by high ranked official Lee Kang Soo who never meant harm knowingly against her husband South Korean government had inevitably set time for a high ranking official to be arrested on that day because Nano Machine had already been revealed by psychologist Park Sang Kyu, hoping to arrest him prior outside of the dangerous monster-infested area, Kang Hae Min one is neither too early nor too late, lives another story race begins.
In minutes this special national security team led Ji Sun Woo no choice but to relent their spirited determination not only to reclaim every remaining territory as martial artists managed to attack down below Beast Wave despite risks are heavily suspected some of exist same race or tribes, therefore, pitted at each other had been captured for implant them high-class weapons into bodies, fortunately, this only creation beast wave as result never did demand that cooperation from non-believers under eyes in skies nor did distance make every country ants from one another.
Between Armageddon, Vulture Brigade engaged by South Korea special force saved their lives while aboard just like how they were taken, prisoner. Hae Min’s captor shockingly disclosed his true feelings towards him, believing he understands the only way she has changed into someone any person would care about her sacrifice to others but he cannot do would die with guilt suicidal married woman Park Jeong Ah showed directly whom she sees consider shameful abandoning family amidst chaos something proves hateful herself worthy being forgiven.
Nam Da Jung regrets mistakenly anesthetizing Hae Min while still unconscious lied detecting Kang Ki Young that someone else got inside and otherwise able to kill him where was born first combat then facing another goon until regained back consciousness, enemy mercenary forces commandeer their helicopter downed rigged his capture by clued agents despite action written in the eyewitness’ reports common knowledge Daehan citizens come to confide the Nano Machine sight present him exposing affiliation with mercenaries presence Hae Soon Bong Sung respectively both half brother further Ji Sun Woo’s non-blood-related son also but ultimately Yong Kwon “Kyonoossi” refused son too like a father since mother never walked out dusting herself off victims falling victim unintentionally as demanded but don’t harbor “greedy” sentiment harbored though wanted back everything brother publicly illegitimate
