Writing blindly
Background story: In 2099 AD, the "Heavenly Crack" came, and the "wild dust" scattered by the golden rift transformed living creatures into strange beasts from the "Book of Mountains and Seas". The first batch of "ferocious beasts" (Qiongqi, Enlightenment Beast, etc.) Followed and the human defense line almost collapsed. In 2102, when the soldier Chen Jiu was about to die, he awakened the "Yinglong" bloodline and killed Taozhu, proving that the "Ancient Bloodline" sleeping in human beings had formed a contract with the prehistoric existence, and the "Desolate Suppressor" was born.
The survivors retreated to seven "Xu Towns", relying on "Xuanhuang Stone" to isolate the wasteland. About one in 10,000 humans can awaken the "Desolate Skill". The purity of the bloodline determines the strength of the ability (from weak support to the destruction of the world), but power comes with a price - backlash, mutation and even being possessed by the remnant soul of the ancient god to become the "Desolate Lord".
In the 20th year of the Era of Desolation (2122), the rift continued to expand, and the master of the desolate world secretly awakened. Frequent strange things happen in Donghai Zhenxu City. The "Vein Eater Fish" (an unknown beast that swallows the blood of the ancient times) appears. The soldiers guarding the "Bloodline Bank" disappear. A conspiracy against the desolate people quietly unfolds. The "Dingshui Pattern" birthmark (bloodline of Dayu) on the left arm of Ye Fan, a boy from Chengwei District, will awaken from the attack of the Vein Eater Fish. With the power of "sealing and subduing" as the core, it echoes the ancient story.
