Long Zu 2

Zero transformed into a dragon and destroyed all the fighter planes, and escaped Black Swan Bay with Renata, heading to the east. On the way, being pursued by various forces, Zero, whose body gradually withered, chose to make a secret deal with Anjou.

On a stormy night of the typhoon landfall many years ago, Chu Tianjiao and his son Chu Zihang broke into Nibelungen and were pursued by Odin. Chu Tianjiao guarded the mysterious black briefcase and fought Odin and the Death Servitors alone, while Chu Zihang awakened due to the stimulation of his bloodline.

On Lu Mingfei's birthday, Chu Zihang came to the class reunion, claiming to be his younger brother.

Chu Zihang and Lu Mingfei figured out the perpetrator of the south station incident with the help of Nuonuo's profiling ability. After nightfall, Chu Zihang went to the Runde Towers alone to perform the mission without telling Lu Mingfei, and was attacked by the Yanling King's Chosen Servant.

Chu Zihang's mission is getting more complicated and he has less and less time to complete it.

At the annual meeting of the Cassell School Board, Anjou initiated the Nibelungen Plan, a project aimed at training a savior who can break through the limits of hybrids and fight against the soon-to-awaken Dragon Kings. Caesar attended the meeting as a candidate.

Lu Mingze wishes Lu Mingfei a happy birthday, tempting him with power in exchange for his life. Lu Mingfei refuses and formally bids farewell to Chen Wenwen. Afterwards, Lu Mingfei and Chu Zihang are forced to delay their return to school, and encounter a little sister who falls from the sky.

Xia Mi is invited to stay at a hotel with Chu Zihang and Lu Mingfei. Xia Mi and Chu Zihang share similar interests, while Lu Mingfei becomes the third wheel. Early next morning, Lu Mingfei receives a message from Lu Mingze, informing him of an important event.

Anjou rushes to the auction with Lu Mingfei, and defeats some assassins along the way. Upon arriving at the venue, Lu Mingfei, dressed in the attire of a nouveau riche, joins this feast of hybrids, waiting for an "unexpected encounter."

Lu Mingfei and the mysterious Muslim girl bid against each other for the Seven Deadly Sins, forcing him to use a temporary Yanling. He remains unaware that this entire scheme is orchestrated by the boss behind Sakatoku Mai. After the auction, the mysterious girl draws suspicion and encirclement from various factions, including the Thirteen Nobles.

Anjou and the Thirteen Nobles part ways due to ideological differences. He takes Lu Mingfei to the theme park to meet up with Chu Zihang and Xia Mi, but encounters a roller coaster accident. Lu Mingze once again tempts Lu Mingfei to trade his life to resolve the crisis.

Under the influence of Zero Time, Chu Zihang resolves the crisis by unleashing his Blood Rage, but is severely injured. Fortunately, he is saved by Xia Mi. Following this incident, the School Board believes that the Dragon Emperor of Earth and Mountain has awakened, and begins to suspect Chu Zihang's bloodline.

Following the theme park incident, Chu Zihang and Xia Mi grow closer, while Anjou's conflict with the School Board intensifies, putting him at risk of being fired. Meanwhile, the Well of Oblivion at Cassell College, where Constantine's dragon bones are hidden, is breached by multiple intruders.

The intruders engage in a fierce battle, and Lu Mingfei seizes the opportunity to reinforce the barrier around the dragon bones with the Seven Deadly Sins. As the battle intensifies, the mysterious figure and Sakatoku Mai fight in their dragon forms. The earth shakes, and the raging flames destroy Cassell's underground complex, and erupt through the surface.

Lu Mingfei delivers a righteous rebuttal against the School Board's allegations at the hearing against Chu Zihang, but is ultimately overshadowed by Caesar. Although Chu Zihang's bloodline is found to be innocent, he is still rejected by the Seven Deadly Sins.

Chu Zihang learns the secrets of the Nibelungen Plan and must slay the Dragon Emperor to survive. Subsequently, Caesar and Chu Zihang lead their respective teams to Xinguo to carry out the dragon-slaying mission. Meanwhile, various factions begin to gather, searching for the location of the Dragon Emperor.

Chu Zihang detects irregularities in the subway. Lu Mingfei, tempted by Lu Mingze, uses a temporary Yanling to fuse with him and teach some thugs a lesson. Guided by Sakatoku Mai, both Chu Zihang and Lu Mingfei are tricked into entering Nibelungen.

Lu Mingfei is attacked by the Wind Devil Queen in Nibelungen. In the chaos, he gets on the subway and encounters the missing Execution Bureau specialists, kicking off his Texas Hold'em adventure. Meanwhile, Chu Zihang, tormented by inner demons, mistakes the Wind Devils for Death Servitors. At a critical moment, Xia Mi appears.

With Lu Mingze's help, Lu Mingfei wins the card game and finds the Dragon Emperor Fenrir, only to be invited to watch TV together. Soon after, Chu Zihang arrives. He uses Blood Rage for a second time and teams up with Xia Mi to severely injure the Dragon Emperor, but something unexpected occurs.

The subway tunnel collapses, and the Wind Devils invade the building. Caesar leads the hybrids into a fierce battle. Meanwhile, in the tunnel, the dying Chu Zihang burns through all his blood, unleashing Blood Rage for a third time to fight Jörmungandr. Lu Mingze reappears to tempt Lu Mingfei.

Fenrir consumes Jörmungandr and unleashes an apocalyptic Yanling, drawing countless Wind Devils to sacrifice themselves. Caesar uses Blood Rage and upgrades his Yanling to fight the Wind Devils. Chu Zihang uses his last ounce of strength to send Lu Mingfei away, and heads back into a battle to the death. Lu Mingfei once again stands at the crossroads of choice.

Lu Mingze slays the Dragon Emperor with the Seven Deadly Sins, while Caesar joins forces with Parsi to eliminate the Wind Devil horde. With the Dragon Emperor's death, Nibelungen teeters on the brink of collapse. Yet there is no way for Lu Mingfei to escape, and Chu Zihang lies on the verge of death.

Renata and Zero met in Black Swan Bay and became close friends. They vowed to escape this cruel experimental facility together. But on Christmas Eve, the night of their planned escape, Black Swan Bay was engulfed in flames. A crazed mob blocked Renata's escape route.

Renata fled with the unconscious Zero in her arms, only to be bombarded by fighter jets. On the verge of death, Zero woke up, reviving her and summoning the Black Dragon to annihilate the enemy. Although the truth of history lies buried beneath the snow, Renata and Zero have been reborn under new names, and the story continues...
