Sign In to the Classic of Mountains and Seas from the Start

Su Yu transmigrates into the role of the Heavenly Demon Sect's strategist, with a special identity as an undercover agent.

Just as the net is about to close, the Brightness Sect, his contact on the other side, is ambushed by a mysterious force and destroyed overnight.

Su Yu, a good-for-nothing cultivator who cannot awaken his Soul Life Spirit, is in mortal danger now that he has lost the Brightness Sect's support.

At the crucial moment, the System awakens and binds itself to the Classic of Mountains and Seas, granting him the ferocious beasts from its pages as Soul Life Spirits!

He can also perform a sign-in on the corpses of demon beasts to claim a wealth of rewards.

[Sign-in on the corpse of a Hidden Void Lizard, obtain the Heavenly Concealment Technique!]

[Sign-in on the corpse of a Scarlet Flame Tiger, obtain the Scarlet Flame Tiger Whip, a spirit weapon!]

[Sign-in on the corpse of a Yin-Devouring Demon Dragon, obtain...]

Slay demons and sign in to grow stronger!

What's more, Su Yu accidentally delivered four boxes of love letters to the wrong woman.

With no other choice, he must slay demons and cultivate while juggling four relationships, one of them with Mo Zhiqing, the Heavenly Demon Sect's cold-blooded sect master, a ruthless killer!
