After being fired, Lu Qingjiu finally decided to return to his hometown to farm.

At first, he started raising a pig, and then he found that the pig could solve more high-level math questions than he could.

After that, he started raising a flock of chickens, and then he found that his own fighting ability was one-tenth of that of a single chicken.

Finally, Lu Qingjiu finally realised that this old home wasn’t quite right… Especially a certain person by his side who constantly stared at him day in and day out.

Lu Qingjiu: “Are you drooling because of the spicy stir-fry I’m holding or because of me?”

Bai Yuehu pointed at the stir-fry.

Lu Qingjiu: “Then can you let go??”

Bai Yuehu reluctantly glanced at Lu Qingjiu’s arm, before loosening his teeth.
