As Gao Yanshou anticipated, when his archers fired a volley, the enemy's heavy-armored Mo Dao soldiers would inevitably move slowly. At this time, sending cavalry to harass them, even if they couldn't kill many, would be enough to create considerable panic.

However, to his surprise, the Tang Dynasty was already prepared.

As the Goguryeo arrows rained down, shield soldiers suddenly appeared behind the Mo Dao soldiers, protecting the Tang Dynasty's Mo Dao army completely.

In fact, even without shield bearers, the full suits of armor worn by the Mo Dao soldiers are sufficient to deal with ordinary arrows.

However, the Mo Dao (陌刀) weapons were very expensive. Even with the strength of the Tang Dynasty, it could only maintain a number of 5,000; any more would be unsustainable.

Therefore, even losing one person would be an unbearable blow for Li Shiji.

Seeing that the Goguryeo light cavalry dared to come up and act arrogantly, Li Shiji immediately sent out the archers in his army to fire a barrage of arrows at them.

In the second round, the Tang Dynasty suffered zero casualties, while Goguryeo lost a large number of its troops.

The two sides were locked in a stalemate, with Goguryeo unwilling to commit suicide and Tang Dynasty unwilling to advance rashly.

It wasn't until Gao Yanshou brought over the heavy cavalry that the situation on the battlefield began to change.

This noise made Gao Yanshou extremely uncomfortable, as if he had swallowed fly droppings.

The reason was simple: the Tang army, which had been so aggressive just moments before, had suddenly mounted their horses and fled...

"You naughty boys, hurry up and ride your horses, hahaha!"

Li Shiji took the lead, leading 10,000 men in a frantic retreat.

In fact, those who could accompany Li Shimin on his campaigns were all seasoned veterans who had survived countless battles. As soon as they saw that the enemy's warhorses were all clad in armor, they knew they had encountered a tough opponent.

Therefore, without waiting for Li Shiji to give them a heads-up, they began packing up their equipment and preparing to flee.

Upon hearing Li Shiji's command, they ran even faster, quickly leaving the Goguryeo army far behind.

Gao Yanshou was furious when he saw the Tang army running away like rabbits.

However, no matter how angry he was, his heavy cavalry was far from being able to catch up with the Tang army's light cavalry.

Therefore, after he had calmed down, he could only order his heavy cavalry to control their speed and conserve their strength, so that they could give the Tang army a good beating when they reached their old camp.

Gao Yanshou knew the terrain of this area very well. This narrow strip of land was only twenty or thirty li long. As long as he caught up with them, the Tang army would be unable to pull off any tricks they had!

The situation on the battlefield changes in an instant. The Tang army, which had just been launching the main attack, ran away in the blink of an eye, and ran away very decisively.

All of this was observed by Li Shimin and Li Jue, who were lying in ambush on the mountain.

"Grandpa, General Li Shiji is so amazing!"

Li Shimin smiled slightly upon hearing this, and then asked with a grin.

"What's so great about it?"

"Grandpa, General Li Shiji has such strong control over the army. He can command so many people without causing any chaos."

"And our Tang Dynasty soldiers are amazing! Just now, one of the soldiers was retreating and he even remembered to pick up a few arrows shot by Goguryeo..."

"They really know how to live frugally..."

"Hahaha!"
