The Male Side Character Cultivates Immortality, While the Heroine Is Sacrificed

I am the senior disciple of the Great Sun Sect, an upright and kind person.

Justice has defined the first half of my life.

I want to be a good person in the second half, too!

[Congratulations, Host, you have awakened the Backstab System]

[Three people have reached an intimacy level of 80 with the Host. Please betray them.]

What?

But I'm a righteous cultivator.

Those are my dearest friends and brothers, as close as family!

[Backstab target detected]

[Backstab mission issued]

[At Fang Xiang and Nangong Yaya's wedding, take Fang Xiang's place in the bridal chamber.]

[Mission reward: Saintly Heart]

Jiang Sheng: "Yaya, even if you threaten me with your innocence, no one will believe you. After all, they all say I'm a good person. Heh heh heh."
