Before meeting Luo Hou, Hong Jun had never been threatened by anyone, nor had he ever feared anyone's threats. Naturally aloof, he turned a blind eye to everything happening in the prehistoric world. But after a battle with Luo Hou, he fell, and found someone he wanted to protect even at the cost of his life. From then on, Hong Jun, the prehistoric world's foremost celibate heartthrob, went further and further down the path of insanity.
Whoever wants to be the Dao Ancestor can have the job. Anyone who gets in the way of his pursuit of his beloved gets beaten to a pulp; if Hong Jun can't beat them, he'll resort to underhanded tricks. If a problem can be solved with force, there's no need to use his brain. He needs to save all his thoughts for winning over the person he loves.
But... why is dating so difficult?
He schemes every which way to trick the Demon Ancestor into his arms, even arranging all sorts of chance encounters. Just when they finally get together, the Demon Ancestor starts having second thoughts. His partner wanting to run away every day is already more than enough to keep him busy, and now rivals keep trying to steal his sweetheart. Looks like he'll have no choice but to master the art of turning hostile. He's petty, he's jealous, so what? A real man should be able to wield a sword, bend his waist, protect his partner, and beat away every peach blossom. Anyone who dares covet his wife had better get ready for a beating.
