章 407: Chapter 405 Wheat Harvest(3)_1

"What makes your ballista different?" Si Jinhan asked seriously. Speaking of the ballista, Tianji Building had already made them a while ago, but because the ballista was not convenient enough, and the angle could not be adjusted at will, its role on the battlefield was not significant.

"The ballista I designed is slightly different from what you currently have. Once the Third Son hands the blueprints to the craftsmen at Tianji Building, they will explain the difference to you." Lin Ziyin replied indifferently.

Chu Suifeng glanced at Si Jinhan impassively.

Immediately Si Jinhan fell silent, unable to resist a bitter smile in his heart. The Prince's ignorance towards the matters of men and women gives his many aides a bit of a headache. The Prince is already twenty, the Wang Residence needs not only a lady of the house but also a successor.
