After the imperial court dismissed, Gu Yun went to neither the Northern Camp nor Ling Shu Institute, but returned to the Marquis's Manor and went to his house's arena.

"What is the Marquis looking for?" Uncle Wang asked.

"A Wind Slasher… actually, it was only a stick." Gu Yun moved past the group of iron puppets in the yard to walk inside.

The Gu family had given birth to military generals for ages. At Gu Shen's generation, it had reached the point where he could hold the Black Iron emblem, his status was equal to that of royalty. His power and reputation had reached the highest point. In the arsenal, there were legendary weapons accumulated through generations of his ancestors. Upon entering the door, there was an unspeakable awe-inspiring aura. Inside, there were many simple and old swords and blades, while those outside were more or less reinforced with fire engines. Among the weapons collected here, some had drunk countless blood, and those that had never been used, they were all on display quietly, dignified and ferocious.

Uncle Wang called several family servants to carry out a big box to Gu Yun. "What kind of Wind Slasher are you looking for? We have everything here."

"One that is less than a foot long," Gu Yun thought that Uncle Wang had watched him grow up, there was nothing to be embarrassed about, and laughed again. "Actually, it's not really a Wind Slasher, just an imitation, it was hollow inside, for children to play with… cough, I just suddenly remembered it is all. It's alright if we can't find it, perhaps it has been lost for a long time now."

Uncle Wang made an 'Ah' in response and slowly said: "That one, of course, it is still here, wait for me to find it for you."

He ordered people to move the ladder, placed it against the wooden cabinet with a lot of bows on display, then intended to climb up himself. Gu Yun hurriedly stopped the trembling elderly man: "Let me, please slow down."

"On the top of the cupboard, there is a small box," said Uncle Wang. "All of the Marquis's playthings from when you were a child are in there."

Gu Yun climbed up the ladder according to his words and found an iron box on top of the wooden cabinet. He brushed the thick dust on it and opened it. He saw that there was a set of small toys like armor, helmets, and wrist guards, which were not made of black iron. They were light and delicate. Gu Yun never knew that he had these toys when he was a child. He was stunned for a long time and couldn't remember when he had them.

Besides those, there were other toys such as slingshots, steam-powered ponies, and other things children played with in the box, as well as a "Wind Slasher" less than a foot long.
