Su Yanci's first cycle began in Kunlun's Nine Void Gates. He accidentally touched the "gazing taboo" on the third head from the left of the Enlightened Beast, and was instantly torn to pieces and reset. As the number of cycles increases, she gradually discovers the secret of the "Illustrated Book of Wild Beasts": the bronze ghost face on the title page can reveal the annotations of predecessors, and the illustrations of strange beasts on the inside pages will change color as the rules are triggered. In the copy of "Qiongqi Trial", she witnessed the breaker's nose being eaten by Qiongqi for rescuing the weak, and then she understood the "dispose of rotten to ensure safety" marked in the illustration - this ferocious beast indeed "specializes in eating loyal people" as recorded in "The Classic of Mountains and Seas", and can only survive by pretending to be evil.
The cycle enters the 47th time. Su Yanci meets Lu Jingxing, a history student who holds the other half of the illustrated book. The two discover that the rules of different copies are related: in the "time zone maze" governed by Zhulong, observing the ancient ritual of "solar eclipses do not summon ghosts" can avoid time backtracking, and this happens to form an intertext with the "day and night opening and closing rules" of the nine gates of enlightened beasts. They teamed up to solve the "Nine-Headed Rotation Puzzle", but triggered an even more terrifying "rule pollution" - the human face of the enlightened beast began to recite the tampered taboos, and the strange list of sacrifices was mixed with modern items.
In the final cycle, Su Yanci noticed that the "Xia people ghost writing" on the remaining page of the illustrated book matched the pattern of the bronze ghost face, and after splicing, the four keys of "Heaven, Earth, Humans and Ghosts" were revealed. The moment Zhulong opened his eyes, he took the risk to break the iron rule of "Don't look directly into the eyes of gods" and discovered that the so-called cycle was actually a repeat of ancient sacrifices, and the ultimate taboo of "Zundu cannot be touched" was to prevent the breaker from discovering the truth about the sealing of the strange beasts.
