Bound together by an imperial arranged marriage, Li Yuyan is scorned for her association with the ill and blind crown prince. Publicly, she stands up for the seemingly gentle and perfect prince, and he in turn protects her from criticism. Privately, she contemplates inheriting a fortune if he dies, while he considers eliminating her if she steps out of line. Unknown to all, the beauty and brilliance they keep hidden will unveil. During their wedding night, as she cures his blindness and cold ailment, but not his secret illness, she discovers the deceit. Realizing she's been tricked, she tries to flee, only to find herself trapped by him as he expresses his fascination with her.

Blue Star has entered the extraordinary era, everything is evolving, and monsters are rampant.

Humans awaken their star souls in evolution to fight against raging monsters.

Zhou Xuan, who was doing odd jobs in the Demon Town Tower, accidentally awakened to an unscientific sign-in system.

Sign in on the ancient desolate beast and gain the power of the wild. Sign in on the weed spirit, and the star soul evolves into the nine-leaf sword grass.

The thousand-year black turtle, the ten thousand-year sea king, the immortal true phoenix, and the sky-swallowing dragon have all become the targets of his registration.

There are countless monsters in the Demon Suppressing Tower, Zhou Xuan signed in silently, and if he was not careful, he would be invincible.
