Meng Shi Zai Shang

In order to save the world, I'm forced to accept the male MC as my disciple! But why is he so different from when I met him in our previous lives? He's so innocent and shy now, like a little puppy. Well, since you're so loyal and obedient, I'll take you in as my disciple! Wait... You traitor! Stop pouncing on me!
