The Tang army began to attack, and the heavy shield soldiers at the front began to advance with large shields, while the archers followed behind the heavy shield soldiers with their waists bent.

They must now push forward and wait until they are sure that they can shoot rockets at the head of the capital city of Goguryeo, and then the heavy shielders will stop.

Before attacking, Xue Li had already calculated the distance and marked the location, they knew where to go and then stopped to attack the capital of Goguryeo.

The Tang troops slowly advanced forward, and as soon as they entered the attack range of the Goguryeo soldiers, the Goguryeo soldiers at the head of the city immediately launched a fierce attack on them with the city defense equipment in their hands without mercy.

Countless arrows and stones flew down from the city, but those arrows could not penetrate the large shield of the heavy shield soldiers, and the archers of the Tang Army were extremely safe under the protection of the heavy shield soldiers.

And now they are not particularly close to the capital of Goguryeo, most of those stones can't hit them, even if some stones occasionally hit the big shield, it only hinders the progress of the heavy shield soldiers.

The Tang army used this lineup, and the casualties could be well controlled.

They had thought about doing this before, but they rejected it later, because although this lineup could control casualties well, it was not conducive to siege, and the heavy shield soldiers had no way to climb the city wall with large shields.

Although the heavy shield soldiers can also escort other troops over, as long as the other Tang soldiers leave the big shield of the heavy shield soldiers, without the protection of the big shield, they will also be quickly shot by the Goguryeo soldiers at the head of the city.

So the generals dismissed the idea of attacking the city in this way.

And they are now thinking the same as the Goguryeo people at the head of the city, why did Xue Li think of using this formation to attack the city again?

And when they saw the archers hiding behind the heavy shield soldiers, they also understood a little.

Since they couldn't take the city in one go, they fought a war of attrition with the Goguryeos, escorting the archers to the foot of the Goguryeo capital with heavy shields, and then using the archers to shoot at the Goguryeos.

However, this does not seem to be a good method, although it can bring a little casualties to the Goguryeo, but the losses of the Tang soldiers will be greater.

It's not worth the loss.

But what they didn't know was that as long as they could shoot some of the rockets into the city walls, they would be much easier to handle the rest of the situation.

Those Tang generals calculated that if the Tang army shot from below, and the Goguryeo people shot from above, then the Tang army would definitely suffer.

But what they don't know is that even so, in the case of the Tang army having rockets, it will definitely be the Goguryeo people who will suffer.

Not to mention anything else, if a round of rockets can be fired at the head of Goguryeo City, I don't know how many Goguryeo people will be killed and injured.

And this is only physical damage, the appearance of these rockets can also deter the Goguryeo people and create fear in their hearts.

As long as they are afraid, then when they fight against the Tang army, they will have a psychological shadow, and they will feel that they are at a disadvantage, which will greatly affect the morale of the Goguryeo people.

The Tang army touched the foot of the capital city of Goguryeo at a very small price.

The Heavy Shieldmen began to stick their shields diagonally into the dirt, then pressed them against them with their bodies, and they used their bodies to add their shields to build an impregnable line of defense for the archers behind them.

At this time, it is time for those archers to be reckless.

The archers, who had been hiding behind the heavy shieldmen, were ready, and as soon as the heavy shielders stopped, the archers immediately reloaded their bows.

"Poof!"

"Poof!"

Countless rockets shot out of the full bow and headed for the capital of the Goguryeo people.

Looking at the attacks of those Tang archers below the tower, the Goguryeo people smiled contemptuously.

"Come on, come on, we're more happy for you to have more people to fight us."

They are on the city wall, the Tang army is under the city wall, if the Tang army attacks them with archers, then which is better and which is inferior, you can see at a glance.

When Tang Jun did this, he simply thought that he had too many people and wasted food, and he wanted to exchange some people with them Goguryeo.

The generals of Goguryeo couldn't ask for it, anyway, more than half of the people on their castle tower were miscellaneous soldiers, and half of the real elite soldiers were called by them as reserves for the promotion moment.

The Tang army exchanged its own elite soldiers with their miscellaneous soldiers, and these Goguryeo generals were going to laugh from ear to ear.

However, the next moment, their grown mouths really couldn't close.

Countless rockets fell on the head of the capital city of Goguryeo, a series of explosions rang out, countless Goguryeo soldiers wailed, countless wreckage and broken arms flew everywhere, and even the solid city walls were blown up and scattered bricks and stones.

"What's the matter, it was detonated by the Tang Army there?"

The Goguryeo people are all too familiar with this situation, this is the power of the Tang army's gunpowder bullets.

In the previous battle, the Goguryeo people had already suffered a great loss of gunpowder bullets, and it can be said that if it were not for the Tang army's possession of such a big killing weapon as gunpowder bullets, they would not have lost so badly in the previous battles.

But what is going on now, how could the Tang army throw gunpowder bullets on the city wall.

And it was so many gunpowder shells at one time, how did they get it, could it be those archers or heavy shield soldiers below?

But if it were their hands, it would have been impossible to throw so many gunpowder bullets on the city walls.

What the hell is going on!

And the second round of rocket attacks by the archers of the Don Army was quickly ready.

Once again, countless rockets once again covered the head of the Goguryeo capital, and this time, those Goguryeo generals finally saw it clearly.

It turned out that those gunpowder shells were tied to the arrows and shot at the city, so it is no wonder that so many gunpowder shells bombarded the city at one time.

It is no wonder that the Tang army, which has always been shrewd, would not have sent archers to shoot at them under the tower, so they would really be idle.

They should have thought that there must be a demon when things go wrong, and Tang Jun must have some conspiracy when he did this, and they shouldn't be careless.

But now they know that it's too late.

Countless rockets almost covered the entire Goguryeo capital, and they naturally could not escape death.

"Boom! Rumble! Rumble! ”

Countless gunpowder shells burst at the head of the capital city of Goguryeo, harvesting the lives of countless Goguryeo people, including those Goguryeo generals.

In order to prevent the Tang army from attacking the city, the Goguryeo people specially sent a large number of soldiers to defend the city wall.

Especially now, in order to do a good job in this defense, the city wall was almost crowded with Goguryeo soldiers, and as soon as the gunpowder bullet exploded, it immediately took the lives of countless Goguryeo soldiers.

On the walls of the capital city of Goguryeo, there is mourning all over the field.
