Gourd Valley.
A massive valley.
This valley spans fifty to sixty miles in length, with the outer valley exceeding twenty miles, and the inner valley over thirty miles—it wouldn't be an exaggeration to call it a small basin connected together.
And the terrain of the valley is formidable, with a large river to the left and a vast fissure on the right.
While the fissure is only a dozen or so miles across, it is situated at the entrance to the valley.
Furthermore, given that the valley slopes downward, if heavy cannons were placed at the back of the valley, their elevation would be hundreds of meters higher than that of the valley's mouth.
At this moment, one after another, heavy cannons have been hauled to the peaks behind the valley, overlooking from a height, directly aiming at the mouth of the valley.
