"Zilong, you lead people to attack first, send people to keep an eye on Marudu City, once Marudu City sends troops to support and evacuate quickly, you must not fight with the enemy." Outside the city, Zhang Hao solemnly commanded.

The domestic city is built on the mountain, and there is also a Marudu mountain fortress on the Marudu Mountain, which is not only the military garrison city of the domestic city, but also used as the royal capital of Goguryeo.

It played an important role in the historical development of Goguryeo, and the mountain fortress of Marudu and the domestic city were interdependent and became the capital of each other, and the two cities formed a corner, one side was attacked, and the other side could quickly support.

Zhao Yun agreed and rushed to the domestic city with the team, and now the team led by Zhao Yun is half of the light cavalry of the Longwu Battalion, and the other half is the archers of the Feiyu Battalion.

Before he reached the city, Zhao Yun took out his treasure bow and shot an arrow at the soldiers at the city gate, and the soldiers behind Zhao Yun also bent their bows and arrows.

Although half of the light cavalry here can't catch up with the archers, they are all trained, and a group of people can do a certain amount of damage without aiming in a volley.

There was a mess at the city gate, some soldiers closed the city gate, and the soldiers on the city wall reacted and hurriedly shot arrows outside the city, but Zhao Yun's army did not rush straight to the city gate, and ran out of the attack range of the Goguryeo army after a round of arrow rain.

A round of arrows from the Goguryeo soldiers did not hurt any of Zhao Yun's soldiers, and when the Goguryeo soldiers in the city found that the enemy was not within their range at all, they stopped their movements.

But as soon as this side stopped, Zhao Yun led the army to charge, rushed not far from the city, and fired a rain of arrows at the city wall again, and then fled again.

After doing this several times, Zhao Yun's side was unscathed, but the Goguryeo army on the city wall suffered a lot of losses, and it seemed that the guards inside were beaten out of fire.

The city gate slowly opened, and a group of three or four thousand cavalry rushed out, and the war horses of Goguryeo were relatively short, belonging to the mountain breeding horses, suitable for walking mountain roads.

But in the open space in front of the city gate, there is no advantage at all, whether it is strength or speed, it is not as good as the war horses of Zhao Yun's army, and it cannot catch up with Zhao Yun's army at all.

Zhao Yun led the army to move forward, turned around and opened his bow and arrows, and in a short time, he shot and killed 12/10 of the Goguryeo cavalry.

After rushing out of the range of the archers on the city wall for a certain distance, seeing that they were about to enter the mountain, Zhao Yun's military flag waved for a while, and the army quickly formed a formation.

After the change of formation, a cone-shaped formation was formed, with Zhao Yun acting as a point at the tip, and the army formed a cone, with light cavalry outside and bow cavalry inside, rushing towards the Goguryeo cavalry.

The cone formation is a kind of formation in the ancient ten formations of "Sun Bin Art of War", and the ancient ten formations in Sun Bin Art of War are square formation, circle formation, sparse formation, several arrays, conical formation, goose-shaped array, hook array, Xuanxiang array, water array, and fire array.

The water array and fire array talk about the tactics of water warfare and fire warfare, not a simple battle formation, so Sun Bin Ten Formations actually only have eight basic battle formations.

In this era, the ancient eight formations were commonly used by generals in combat training, and the names of those formations that were well known to later generations had not yet been created in this era.

The Eight Formations of Zhuge Liang, who was the most famous in later generations, is a kind of group compound formation innovated on the basis of this ancient Eight Formations, which can be turned into different formations according to different terrain opponents.

It can be said that this ancient eight formations are the basis of all the formations created later, and people like Zhao Yun, Zhang Fei, and Tai Shici who have read many military books have naturally led their soldiers to practice these formations a long time ago.

The cavalry of the two sides rushed towards each other, and before they got close, the soldiers of Zhao Yunjun's army bent their bows and arrows again and again, shooting at the opponent's army, and when they were almost close, the light cavalry outside put away their bows and arrows and grabbed their spears, and the archers in the middle continued to shoot their opponents.

Zhao Yun was the tip of the conical formation, the first to make contact with the other party, the gentian bright silver spear waved again and again, no soldier was his one-in-one enemy, and he couldn't stop Zhao Yun's progress at all.

Zhao Yun tore a hole here, and the army behind followed behind Zhao Yun, tearing the hole bigger and bigger, and the archers in the middle did not stop their movements, shooting their arrows at the enemy in the distance.

With only one hedge, the Goguryeo cavalry team was killed in pairs, losing one-third of its troops, and the remaining soldiers dared to fight and fled in all directions.

Maybe it's not that there is no purpose to escape, but it's a tactic, once you can't beat it, you will go to other places to seek support, some of the Goguryeo cavalry ran in the direction of Marudu Mountain Fortress, and some went in the direction of boiling water, probably to ask for help.

Zhao Yun didn't care about them, and rushed to the vicinity of the city wall There was another wave of arrow rain, and the Goguryeo officers on the angry city wall scolded, just scold, anyway, Zhao Yun They don't understand.

"My lord, Marudu Mountain Castle has sent troops to the rescue." In the forest in the rear, a soldier reported to Zhang Hao.

"How many?" Zhang Hao looked at the soldier and asked.

"Almost seven or eight thousand." The soldier replied that although Marudu Mountain Castle was specially used to protect the domestic city, it was at most 10,000 troops, and it seemed that there would not be too many troops in it.

"Inform Zilong to retreat, Ziyi, after Zilong withdraws, you take someone to the mountain city of Damaru." After hearing this, Zhang Hao thought for a while and said to Tai Shici.

Zhao Yun was fighting on his side, and suddenly received an order from the herald to retreat, glanced at the domestic city, and withdrew with a wave of his hand.

Seeing that Zhao Yun retreated with the army, the Goguryeo soldiers on the city wall breathed a sigh of relief, although they all knew that reinforcements might have arrived, but no one dared to go out of the city to pursue, and no one even wanted to mention it.

On this side, Zhao Yun retreated, and on the other side, Tai Shi Ci took his men around in a circle, avoiding the army that came down from the mountain to support the domestic city, and rushed to the mountain city of Marudu.

Because the Marudu Mountain Castle was built on a mountain, there was no large cleared space in front of the city gate, and the current Marudu Mountain Castle was only used for garrison purposes, and there were no people living in it, so most of the time the city gate was closed.

Although the Marudu Mountain Castle was built on the top of the mountain, it had a good view, and it was easy to defend and difficult to attack, but because it was also easier to become a live target, Tai Shici did not adopt the tactics of Zhao Yun.

On this mountain, it is not suitable for such a fight, Tai Shici led people to hide in the woods outside the city, scattered into a fan, and did a good job of division of labor, two or three people aimed at an enemy.

With Tai Shici's order, ten thousand arrows were fired in unison, only one salvo, and all the soldiers on this wall were shot and fell.

"Rocket preparation, ignition." Tai Shi Ci gave a loud order, and the soldiers pulled out an arrow prepared in advance, and the arrow was wrapped with rags and other flammable materials.

In the ranks, one person took out the tinder and lit a fire, and the others lit the arrows.

"Forward." Seeing that all the soldiers were ready for the rockets, Tai Shici gave the order again.
