Chen Mo was once the worst loser in Longcheng Martial Arts School. With his Dantian damaged, he couldn't even practice basic boxing skills. It wasn't until he accidentally triggered the ancestral "Breaking Jade" and unlocked the ancient "Nine Revolutions Martial Art" that his energy and blood surged instantly, and his palms condensed with Qingmang Qi that could shatter the defenses of the Grandmaster Realm. Only then did he discover that there was something hidden beneath the peaceful city that could devour warriors. The "Shadow Demon", the culprit who destroyed his Dantian ten years ago, is secretly plotting a bigger conspiracy.
Xia Wanqing, a talented girl from a Longcheng martial arts family, mastered "Ice Fist" in the middle stage of the Qi and Blood Realm, but was forced to participate in the dangerous "Urban Secret Realm Trial" due to family pressure. Her encounter with Chen Mo began with a shadow demon raid: Chen Mo's green light energy shattered the shadow demon's defense, and Xia Wanqing's ice fist froze the evil, and the two became comrades in arms.
From the stunning counterattack in the martial arts school assessment, to the life and death in the secret trial, and then to the revelation of the truth about the shadow demon's control of the martial arts family, Chen Mo broke through many realms with the nine-turn martial art, and Xia Wanqing used the ice fist to escort them, and the two worked together to break through the dragnet set by the shadow demon. The tempering of the Qi and Blood Realm, the competition in the Grand Master Realm, the ancient inheritance deep in the secret realm... The young girls overcome all difficulties with their blood, and finally rise against the odds in the urban martial arts realm, guarding the future of Dragon City warriors!
