Yu Wen Hua rode his warhorse forward, circling around, but could not find a place where the cavalry could break through. Yuwen Tianxian also noticed the placement of the military formation—
Outside the chariots and carriage crossbows, a large swath of poisoned iron rhombuses had been laid.
Then, within the area of iron rhombuses between the chariots and the situation, large crossbow beds were installed with steel spikes pointing outward. Shixuan Machine Crossbows were set up on top, connected by ropes. When someone touched the rope, the crossbow machine would rotate and fire in the direction of touch.
Yu Wen Hua's expression changed drastically, and he looked towards Yuwen Tianxian.
The calm and revered general stared intently at this arrangement of [chariots][machine crossbows][poisoned rhombuses], and after a long while, he said, "It's my combat skill, just once, and he has already blended what I am best at into his military formation."
