I! The Destined Martial Saint!

Su Yu was transported into an urban novel, but he wasn't the protagonist. Instead, he was a villainous side character, a "bootlicker" to the female lead who looked down on him! Heir to a top-tier family, yet he chose to be a bootlicker to a fake high-minded female lead who didn't appreciate him? His grandfather was one of the thirty-six martial saints of Blue Star! His father was one of the nine great masters of the Dragon Country! Who would want to be such a "houseless" bootlicker? Not me!
Bound to the "Destined Villain System," he was threatened by the female lead at the beginning to be divorced? Fine! I'll grant you that divorce! After the divorce, Su Yu embarked on the path of becoming a "Destined Villain" who would dominate all realms and never look back.
"Ding! Congratulations to the host for successfully snatching the female lead, gaining the opportunity: Martial God's Body!"
"Ding! Congratulations to the host for successfully killing the Son of Destiny, gaining the reward: Eternal Body of Calamity!"
"Ding..." Just as Su Yu had plundered the protagonist's last opportunity, Lin Panxi, the female lead who initially mentioned the divorce, suddenly approached him. Lin Panxi cried to Su Yu, "Su Yu, I regret it, can we get back together?"
Looking at the female lead who was crying in front of him, Su Yu was calm for a moment. The next second, he drew his long sword and struck.
"Almost forgot, you're also an opportunity..."
From then on, Su Yu went further and further down the path of becoming a Destined Villain!
