Twenty shield carts in the front row, three hundred Goguryeo auxiliaries with picks in the back, filled with dirt, and three hundred crossbowmen under the command of Guan Xiaotong in the second row, who were to cover the entrenchment.

Seventy paces away were more than 500 Goguryeo auxiliaries who were specially armoured, and they were divided into teams of fifty people, each team had three ladders, this simple ladder had no equipment to cover approaching, only iron hooks on the top, which could be hung on the battlements to prevent them from being easily pushed down by the defenders. There is also a bracket in the middle that can support more people to go up the ladder at the same time, and they will start attacking when the moat is filled. The last row is the 3,000 elite infantry led by Guan Xiaotong, commanded by Guan Xiaotong himself, and as long as there is an opportunity, they will immediately climb the city wall to support.

At this time, in the creaking sound of the front row of shield carts, they soon came to the edge of the city trench, and the rear row of shield carts stopped ten paces away, and a dense number of crossbowmen flashed from behind, aiming at the wall and began to fire suppressively.

Although he gave these more than 1,000 Goguryeo auxiliaries a good future, compared to being able to reduce the losses of the soldiers under his command, he did not hesitate to push these Goguryeo people to the front, and how much he could survive in the end was no longer something that Wang Junlin considered. No one can be merciful to one's own soldiers on the battlefield, let alone to the enemy.

The moats of Daluo Castle were not deep or wide, only about one zhang deep and three and a half feet wide, and the water in the moat was only four or five feet deep.

There are four gates in Daluo City, and the layout of the city is similar to many cities in the Great Sui, all of which are cross streets, and the two main streets run through the north and south and the east and west gates respectively, and Wang Junlin's main attack is the south.

With a shout, the auxiliary soldiers of the trench filled in flashed out from behind the front row of shield carts, and scrambled to pour earth and stones into the trench, and then went back to pick a second group, and the more than 200 auxiliaries also began to run back, also to participate in the work of filling the trench.

The head of the city heard the movement, some figures came out, pulled out the posture and prepared to open the bow, hundreds of fast crossbows under the city shot at the same time, the piercing sound of breaking the air sounded densely, more than a dozen Goguryeo archers were hit, struggling to disappear on the city, the panicked cries of the Goguryeo soldiers sounded, the crossbowmen of the Sui army under the city immediately retreated after launching eight crossbow arrows, and a new batch of fast crossbowmen were replaced behind the shield car, so as to rotate to ensure that the suppressive attack on the city head continued.

"Each stares at the city disc in front of you, don't care about others, look at those who dare to take the lead, every time a salvo, don't release it in advance." Hu Gouzi walked back and forth in the shield workshop, taking advantage of the artillery stoppage to alert the gang leaders.

Guan Xiaotong's 3,000 infantry, including 1,000 spearmen, 1,000 repeating crossbowmen and 1,000 sword shields, at this time, the 1,000 crossbowmen were divided into three rounds, alternately covering the soldiers who filled the trenches.

After more than an hour, the moat was filled in wide enough, and the auxiliaries in the rear howled loudly and swarmed with ladders.

There are many defenders in the city, and after the last time Yuangai Suwen returned to Annan County from the defeat on Bailing Island, he actually guessed that Wang Junlin would one day attack the land, so Goguryeo also made a lot of preparations, and the equipment to defend the city was extremely abundant.

There are several stone throwers in each of the four hundred city walls, and the level of craftsmen in Goguryeo is not much lower than that of the Great Sui, and these things can be easily manufactured, but the performance is far from that of Wang Junlin's side, even if it is inferior to the products of the Great Sui Ministry of Industry.

Goguryeo still has 5,000 soldiers in the city, and there should be some auxiliaries in Daluo City, all of which can participate in the defense of the city, and Wang Junlin's side has no military advantage. Only the momentum and morale are superior to Goguryeo, yesterday Jin Yibei had broken his courage, although they fled back back more than 1,000 people, but out of the city field battle is not courageous.

According to Wang Junlin's plan, the attack is still aimed at seizing the city gate, and this Daluo City does not have an urn city, let alone a jack gate that only a big city has, so the difficulty of the attack is not high.

Therefore, Wang Junlin planned to attach ants to the city on the surface, but considering that Goguryeo had enough manpower at the head of the wall, it was difficult for the soldiers who climbed up to stand on their feet, or that if they wanted to gain a foothold, they would inevitably suffer a lot of casualties, so secretly he mainly exercised the tactic of digging the roots of the wall, and the manpower was still Goguryeo's auxiliaries.

Although these auxiliaries also have a lot of hard-working people, Wang Junlin will not pity them now.

The shield cart in front is to fill the trench, but at this time, the second batch of shield carts in the back is creaking towards the city gate, and there are special combat team scouts around to swim at a distance of two hundred steps from the city wall, the shield cart is still two layers in front and rear, Lu Han sent a thousand people, advancing under the cover of the shield car, and there are two very elaborate stone throwers between the two layers of shield cars.

Soon after entering the five hundred steps, several stone throwers on the gate of Daluo City began to fire, and several stone projectiles flew out, flying high over the head of the shield car line, and smashed on the ground behind them with a bang, and the auxiliary soldiers of the cart screamed, and the two auxiliary soldiers who had a nervous breakdown turned around and fled backwards, and were cut down to the ground by the soldiers under Guan Xiaotong who escorted the car just a few steps.

The soldiers on the Wang Junlin side of the escort car shouted and scolded loudly with their blades, and let them continue to move forward, and the stone thrower on the city tower was fired again, this time it was closer, and the Sui soldiers loudly reminded the auxiliary soldiers that the stone thrower would lose its effect when they approached the city wall.

The auxiliaries rose up with all their strength in a panic, the shield cart went faster and faster, and finally was hit by the stone thrower at three hundred steps, and a shield cart in the back row on the left side broke like a pile of toys, and the fierce kinetic energy of the stone bullet exploded the thick trunk of the bowl into countless pieces, and the auxiliary soldiers of the cart flew with flesh and blood, and the miserable howl sounded to the sky.

The auxiliaries in the shield car array were in chaos, and the soldiers on Wang Junlin's side slashed and killed more than ten people in a row before the auxiliaries continued to advance, but fortunately, the accuracy of the Goguryeo stone-throwing machine was too poor, and it was never hit again.

The rest of the shield carts walked into one hundred and fifty steps safely, the Goguryeo stone-throwing machine had a straight trajectory, and there was a large dead angle after placing it on the city wall, and the bow and arrow basically did not pose a threat to the shield carts.

After entering the hundred steps, the head of the Goguryeo city shouted repeatedly, the Goguryeo soldiers and archers began to shoot, and the fast crossbow team behind the second row of shield carts immediately began to return fire, and people on both sides were shot and fell to the ground, but the shield carts in the front row of Wang Junlin's side still advanced forward to the moat directly opposite the south gate.

The ditch at the gate of the city was not filled, but Wang Junlin's side had a special trench cart for siege, which was quickly pushed up.
