Begging for Forgiveness With an Injury

Upon arriving at the other world, Ren Baqian suddenly felt that he had forgotten something. He furrowed his eyebrows and racked his brain. What did he forget about?

The next moment, he kneeled on the ground.

Erhu? Where's the erhu? Where's the erhu? A stupefied look appeared upon Ren Baqian's face. How could he forget about the erhu again?

Why did he forget about the erhu every time he returned to Earth? Was it destined?

God, why aren't you blessing me?!

Ren Baqian raised his head and let out a deep sigh. A look of agony rose upon his face.

There was no point in sighing now. He had to come up with an explanation for the empress so that she wouldn't pursue this matter.

Even though the empress would not really kill him, she would still be willing to mete out punishments such as making him kneel on glass fragments. Or would she punish by making him train every day? Or maybe she might make him spar with her?

What should I do?
