Elder Mo turned and looked at his first disciple, then he sighed. "Mo Sheng you really should not be hung up on such a person. She'd be the first to leave you in the face of difficulties. And as for your shidi, don't be too angry. He is still young and has seen too little of the world so his actions are a little crude."
He Yuan nodded but he rolled his eyes inwardly. Mo Sheng had also spent all his time in the Duoluo sect like Mo Jiu -they were also age mates- but you don't see him going about sleeping with his fellow disciple's betrothed.
Elder Mo had threatened Shen Mianmian like that in the storyline too but that didn't stop her and Mo Jiu from meeting up either at different inns at the foot of the Duoluo sect mountain or at the other peaks to rendezvous.
