During an ordinary evening self-study session for senior high school students, thirty-two students from Class 7 of senior high school fell into the world of "The Classic of Mountains and Seas" together with the classroom.
The red grass is like blood, the moon hangs in three circles, and the corpses of the predecessors hang on the bronze trees. There is no rescue, no retreat, only one cruel rule engraved on the stone tablet - those who eat beasts inherit their bloodline. One beast has one journey, and it is irreversible. Lin Yu resonates with the auspicious beast Bai Ze and can see the weaknesses of all things; squad leader Su Wan inherits the power of the nine-tailed fox, which confuses the mind and soul; sports committee member Zhou Ye drinks the blood of Kui Niu and wields the power of thunder; transfer student Chen Mona, Xiang Liu's poison, poisons the swamp country; crane tail Lu Yao is protected by Xuanwu and becomes an indestructible shield; mysterious girl Shen Qing bathes in Bifang's fire and is the only one who has been through it. Six people and six paths fought their way through the wild world and finally found their way back. They thought the nightmare was over. But the day after returning to Earth, the world changed. The phoenix trees in the community grew luminous leaves, stray cats turned into ferocious beasts, and the school playground opened a gap leading to Qingqiu. Mountains and seas transformed overnight, and the world entered the age of myth. What they brought back was not ability, but seeds. ——The seeds that allow "The Classic of Mountains and Seas" to merge with the earth. When alien beasts run rampant, the old order collapses, and all forces compete for power, and when there is only a thin line between humanity and beastliness, these teenagers who have just grown up must make a choice: let humans return to the original point, or lead all sentient beings into a new era where humans and myths coexist?
