Chapter 638

City wall.

Li Er sees the Goguryeo army suddenly startled after being hit by the volley of giant rocks.

Many soldiers have already lost their minds. They throw away their weapons, hug the people around them, and bite them with their teeth and hit them with their heads.

That place has completely become a living hell.

Li Er feels waves of fear in his heart.

This weapon is too terrifying!

The lethality is secondary; the shock brought by that volley is enough to make the bombarded army go crazy.

In the distance, Qi Jiguang's army still maintains a neat formation. Moving forward step by step, eroding the lives of the Goguryeo soldiers.

Miserable!

Too miserable to look at!

Li Er turns his head and says to Qin Mu.

"Your Majesty of Great Qin, what trick did General Qi use to be able to force the Goguryeo army back so steadily?" This is what Li Er wants to understand the most.

Frankly speaking, the basis for the victory of this battle lies in Qi Jiguang being able to force the Goguryeo army back first.

"617"

Clearly, Qin Mu had long anticipated this, which is why there was such an arrangement.

And that bet.

Li Er feels he has been deceived again.

But he cannot figure out what method can be used to drive the Goguryeo army back like herding sheep?

A smile finally appears on Qin Mu's calm face.

He seems completely indifferent to the carnage before him.

"Old Li, you are quite forgetful. You have seen that thing before."

"I have seen it?"

Li Er is even more confused.

What on earth have I seen?

Why can't I remember it at all?

Qin Mu does not explain.

"Watch, you will understand in a while!"

The Goguryeo army, jumping into the river, and those killing each other are not few.

It lasts for two full hours.

The remaining 100,000-plus soldiers finally get rid of their panic. They decisively abandon their weapons and choose to surrender.
