They did not have the upper hand in terms of movement speed, and they also lacked war horses, many of which were obtained from the Turks through trade, and naturally they could not afford much with their financial resources.

The advantage of the cavalry of the vanguard was that they did not have, and after a while the Goryeo people felt that the situation was not right, because each time the other side had no intention of attacking.

Is it so easy to go out and walk back, of course not.

This was how the newly arrived soldiers familiarized themselves with the environment, and during this time they drew many maps, and the various points leading to Goryeo were marked.

"The only way to get around the enemy's rear quickly is to go by boat." Based on this period of research, Hebida came to a conclusion.

"No, we're all cavalry, it's too risky to go there by boat." Shi Huaiyi said.

Horses crossing the river have to be carried by boat, and horses can take up more space than people, so they really don't have any advantage in terms of capacity.

Even if you are behind the enemy, you may be surrounded by the enemy because of the unfamiliar terrain.

"Looks like we can use a ballista." Luo Yi said suddenly.

When everyone heard this, most of the chariots brought by Luo Yi were crossbow carts, and the attack distance could be several times that of archers, and it happened to be able to attack Goryeo Silla and form a defensive position.

"Not only does the chariot have a very long range, but it also has fast movement, and if you attack them every day, you don't believe they can still sit still." Ding Qilin said.

"Good idea." Why bother to agree.

After discussing the battle plan, the implementation began the next day, and the ballista arrived at the mountain defended by the Goryeo, and lined up far away, and the Goryeo people hid in the mountain, thinking that the natural mountain peak was a cover, and was indifferent to the soldiers and horses of the Sui State.

They knew that none of the archers could hurt them.

"Look at those people from the Sui Kingdom who are tossing around again, we haven't slept peacefully since we came to quarrel every day during this time."

"Just pay attention and see what tricks they play."

Many Koreans watched from a high vantage point, not at all worried, as if danger had never approached.

"What they're fiddling with, it's a ballista, and I've heard it's a long range."

"The key is whether it can hit or not, don't think about it, look at things that don't need it."

While they were chatting, a sudden rain of arrows suddenly came at them.

"Ah~"

There were many people who were hit by arrows, and they couldn't imagine how the Sui people did it at such a distance and such a high distance.

In fact, it is not difficult, the angles of the ballistas they use are all parabolic, and the arrows are adjusted after measuring the angle, and it is not uncommon for them to hit the enemy.

The problem is that the first round plays a big role when the enemy is not paying attention, and then the second round is not obvious, but it still makes the opponent nervous.

Su Gavin heard a report from the defending soldiers that the ballista of the Sui State could kill them, and immediately went to the battlefield in person, and the arrows fell on his side, and he didn't react at all.

Such a move calmed down the panicked soldiers.

Su Gavin was dressed in a drape, with two long knives on his back, and two knives hanging from his waist, which looked a little weird, but his appearance could immediately stabilize the mood of the soldiers.

Such a general is really difficult.

Su Gavin looked down the mountain and saw that the rows of ballistae were still continuing to attack, and many soldiers on the cliff were hit by arrows, and the arrows of the Sui State were as if they didn't want money.

"Be hidden, hide all." Su Gavin also has no good way to do it, so he can only avoid the edge for the time being.

Just when he wanted to observe again, he found that the ballista of the Sui State had been transported away by the carriage, and Su Gavin looked at the way the carriage was so slow, and suddenly had an idea in his mind, but he didn't do anything else.

"General Luo, it seems that there are some effects, but it is not a way to consume arrows like this." Ding Qilin said.

"Let's see how it goes for two days." Luo Yidao.

The next day, Ding Qilin and Luo Yi came again, and when they saw the Goryeo soldiers and horses haunting the cliff, they immediately had several rounds of arrows, and when they saw that it didn't work, they beat the horses again and left.

On the third day, it was still the same, but the Koreans learned smartly, so they didn't show their heads at all, and let Luo Yi leave early after two rounds of arrows.

Just as Luo Yi had just left with the carriage, the Goryeo soldiers who had hidden their bodies with soil on the mountain suddenly broke through the ground, and thousands of people rushed out of the chariot in an instant.

Seeing this, Luo Yi immediately asked people to fight back, using bows and arrows to stop the pursuers.

Su Gavin watched the speed of the Sui State's ballista from the mountain very slow, and their men would soon be able to catch up, thinking that with this kind of sharp weapon, they would be handy in defense in the future.

What he didn't know was that he had fallen for it.

The chariot is not a carriage for transporting goods, and the biggest feature of the chariot is that it is flexible and mobile, and how to do the chariot without flexibility, just when the Goryeo soldiers are about to pursue it.

The ballista behind Luo Yi began to exert force, and the arrows were quickly released, and a few people who breathed thousands of arrows had not been able to keep up.

The chariot suddenly accelerated, throwing the enemy far away, and at this moment, a cavalry suddenly galloped past and wiped out thousands of enemy soldiers and horses.

Su Gavin saw it clearly on the mountain, he knew that he was so cautious and cautious in the end, he was careless, and he found the enemy's way, he did not feel regret, but realized that the enemy he faced was more terrible and difficult to deal with than he thought.

For this sneak attack mission, for fear that the enemy would find out, Su Gavin ordered 5,000 men to cover it with soil in the middle of the night and hold out until the Sui soldiers and horses appeared.

How could such a ruthless person be sad for the demise of thousands of people, what he cares about is the result, success or failure, and the first thing he does when the action fails is to summarize the shortcomings.

Su Gavin realized that the enemy was strong, and the previous defensive tactics could no longer continue, and he was not afraid when facing millions of Sui soldiers and horses, because he knew that he could use a natural barrier to drag down the enemy.

They also can't afford to drag it out, but compared to the effect of a million soldiers, their 200,000 soldiers and horses are nothing.

He saw the strength of the vanguard when he was attacking the city, and today he saw that the vanguard is powerful, and the general who leads the army is not a fool who can only charge.

In the face of such an enemy, his emotions were mobilized, he is the kind of person who is strong when he is strong, and he does not admit defeat in anything.

Luo Yi and Ding Qilin cooperated very tacitly, cutting the enemy by five thousand, and they were very careful when they cleaned the battlefield, anyway, the Koreans could only watch from above.

It will be very annoying to watch, want to defeat the opponent, anger the other party is a method, once people are angry and do things, they rarely consider the consequences, as the saying goes, you can do anything when your brain is hot.

Their strategies also include these, and how to do it is the subtle play of the generals.
