He had clearly and truly done some disrespectful things to little yifu in his dream.

He buried his face in the blanket and screamed. He was utterly disgusted by himself, too ashamed to see anyone ever again. He wished for nothing more than to simply hit his head against the bedpost and end his life now.

This time, even the ruined blade could not help to calm him down.

Just as the boy was in a state of confusion and suffering, the sound of knocking on his door almost scared him out of his skin.

The first reaction was rolling up the bed sheets into a ball in a panic. He clenched his teeth, forcing his mind to stabilize, then dragged his feet over to open the door.

Unexpectedly, as he opened it, he was struck with a second wave of surprise.

Standing in front of the door was a figure whose height was taller than a person, and was made entirely out of iron. There were two small round eyes under the helmet, flashing purple, the color that was unique to the burning of Ziliujin - it invoked a frightening image, enough to be the main character in nighttime ghost stories.

The iron figure looked straight forward and over the top of Chang Geng’s head, staring aimlessly behind him, lifting its hand the size of a bowl. Resembling a woodpecker, it continued to endlessly knock on his door.

Chang Geng's soul that was scared out of him was still doing its frantic dance in the air. He was not able to gather himself together. When he was already met with this situation, the hairs that had not been able to lie down stood up once again.

He took a deep breath then hurriedly stepped back, grabbing the sword hanging at the door.

At this moment, Gu Yun stepped out from behind the iron figure and asked with enthusiasm: "Interesting, isn't it?"

Chang Geng: "..."

Not!

"I know the family guards have not dared to use weapons against you, and from what I heard from Uncle Wang, you always practice your swordsmanship by yourself in the courtyard every day, which could be quite dull and boring since you have no opponent,"

Gu Yun said all this while casually twisting and turning something at the back of its head, the terrifying iron monster instantly became perfectly still, standing motionlessly in one spot. Gu Yun raised his hand and patted its giant iron head. He smiled at Chang Geng and said: “Hence I brought a ‘sword training puppet’ for you to play with, sounds good?”

Chang Geng’s gaze didn’t dare to stay on him for too long, he looked up at the immobile iron monster resembling a mountain.

After a moment, he pointed at himself: "Me? Play with it?"

Isn't this thing the one who was going to play with him?
