"From what I know, sexual Gu causes those afflicted by it to lose all conscious thought. Their entire person would pledge allegiance to whoever cast the Gu. This is because the targeted person believes that he or she has fallen in love with the caster and would be willing to pay whatever price so long as they can protect and be beside the caster. I've also heard that, as long as you have sexual Gu, you can induce two people to stay together for their whole life and be inseparable for all eternity." The businessman explained while massaging his temples. He then asked, skeptically, "Is it really that powerful?"
"HAHA! I never thought that someone from your group would know this! So, young man, what do you think? If you need some, I can sell it to you on the cheap, how about that? Hahaha!" Wu Ling looked at the businessman and burst out in maniacal laughter.
