A large number of shoddy stone throwers on the Goguryeo side also began to fire, and the stone projectiles flew and projected the earthen wall of the defense side, smashing up a mass of scum, and after three rounds, the tide of shield carts came towards the earthen wall, and the Goguryeo soldiers actually launched two rows of shield carts this time, and there were even as many as three layers in the middle.

Liu Yidong stood at the head of Bai Lingcheng, condescending, controlling the overall situation, giving orders one by one in an orderly manner, the defending side was like a precision machine, running in a tense and orderly manner, everyone was a part of this huge machine, playing their own role or function.

When the Goguryeo soldiers entered within 700 paces, the stone throwers on Wang Junlin's side began to shoot in turn, and the heavy stone projectiles smashed those seemingly sturdy shield carts in all directions, screaming and screaming.

As soon as the two sides fought, the battle was fierce, the screams on the battlefield did not stop, and people died all the time.

With the experience of the fierce defensive battles of the previous two days, the defensive tactics of Wang Junlin's side have become proficient, and everyone knows very well what they should do and when. Six hundred paces later, the long-range crossbow also began to be fired, and the shield carts were smashed to pieces, and the Goguryeo auxiliaries who pushed the shield carts screamed miserably.

After entering the pothole area, the shield carts of the Goguryeo people stopped one after another, and the auxiliary soldiers rushed out from behind, risking their lives to throw dirt bags one by one into the holes, with the experience of the previous two days, they were much faster than the previous two days, and they did not have the fear and panic of the previous two days.

It's just that while they are filling in the pits, they are cleaning up the wreckage of the shield cart they left here two days ago, so that the progress is very slow.

All the auxiliaries howled as hard as they could, pushing the shield cart desperately forward, and no one thought of dodging, their faces were numb, they were all resigned to fate, thinking that they would die.

When the distance was close to a hundred paces, the soldiers in the front trench of Wang Junlin's side continued to fire with bursts of crossbows, and the Goguryeo auxiliaries who were responsible for clearing the obstacle were suddenly killed and wounded even more.

With such a quick and high probability of being killed, these auxiliaries finally became afraid, but as long as anyone dared to stop, they would immediately be shot to death by the overseers on their own side behind, thus forcing all the auxiliaries to continue to advance, without any protection, risking death to clear obstacles and fill pits, almost every time a pit was filled, a dozen Goguryeo auxiliaries would die.

In this way, the potholes were filled one by one, and the shield carts advanced little by little, but the Goguryeo auxiliaries were constantly decreasing, while the long-range strong crossbows, stone throwers, continuous fast crossbows, and ordinary bows and arrows on the side of Wang Junlin were still fierce, harvesting the lives of the enemy.

All the attacks seem to be chaotic, but in fact, the coordination between each other, the filling of gaps, and the combination of long-range and short-range are all carefully studied before the battle, and scientifically configured according to the local science, so as to ensure that the attack power is maximized, and no attack is wasted as much as possible, so as to continuously destroy those shield vehicles, shoot those Goguryeo auxiliaries, and break up their formations, destroying their will to fight.

After half a day, the Goguryeo soldiers finally advanced to 90 steps from the earthen wall, which was the effective range of their bows and arrows.

As the Goguryeo general in charge of the advance command gave an order, a horn sounded, and thousands of light arrows rose into the sky and poured down towards the Sui earthen wall on the defending side, finally sending out the first large-scale counterattack on the Goguryeo side since the beginning of the war.

However, the effect of such a counterattack made Yuan Gai Suwen, who was witnessing this process from a distance, look extremely ugly.

The hanging curtain on the earthen wall of Wang Junlin sounded a dense popping sound, the hemp quilt against arrows seemed to be overgrown with weeds in an instant, and the hanging curtain on the earthen wall seemed to be weak, but the strange thing was that all the bows and arrows could be blocked, and none of the arrows could penetrate this hanging curtain, and occasionally there were arrows that shot higher before they could fall behind the earthen wall, bringing a miserable scream from time to time.

In short, most of the tens of thousands of arrows fired diagonally by Goguryeo were blocked, and the soldiers on standby behind the earthen wall hid under the hanging curtain, and there were hanging curtains made of wooden frames with linen quilts on top of them, which effectively resisted bows and arrows.

The so-called "everything is foreseen, and if nothing is prepared, it will be wasted", and the advantages and advantages of a fully prepared defensive battle are vividly reflected at this moment.

The defending side fought back behind the breastwork and shot the Goguryeo soldiers who filled the pit, and the two sides entered the counter-shooting, but this kind of counter-shooting was too unfair, and the Goguryeo side often had tens of thousands of arrows to shoot a dozen people, but the defending side could shoot a dozen Goguryeo soldiers with a hundred arrows.

The defense behind the earthen wall was orderly, and in some cases that could not be seen, the observation posts on the castle head behind or on the hillsides on both sides would constantly transmit messages and send information with arrows.

……

……

Wang Junlin observed the enemy camp with a telescope, his own side attacked violently, the long-range attack was very accurate within a hundred steps, the fragments of the shield car were continuously exploded on the front line, and the screams of the Goguryeo people sounded in pieces, but there was no obvious reduction in the shield car of Goguryeo, after being hit and stopped, one was bypassed behind and added to the line, and the auxiliary soldiers were also endless, the front just fell, and a group of auxiliary soldiers were driven out after the shield car.

The shield cart stopped between seventy and eighty steps, and countless Goguryeo auxiliaries worked desperately in front of the shield cart, piling up the remains of the shield cart left in the previous days in front of the new shield cart, and thousands of Goguryeo archers behind the shield cart pulled their bows and threw them, and after five or six arrows, they replaced them with a round, maintaining their physical strength, and the rain of arrows seemed to not stop, even if the soldiers on Wang Junlin's side had a special hanging curtain, there were still casualties.

The shield workshop flashed some of the sharpshooters selected by Goguryeo, their marksmanship was accurate, and they were often able to suppress the Sui soldiers holding a burst of crossbows in the barricade ditch, after all, the defending side had a lot of strength difference than the other side, in order to reduce losses, they had to retreat to the earthen wall in turn, climb those crooked passages and retreat through the trench, enter the breastwork in front of the earthen wall, and continue to shoot the enemy relying on the breastwork.

In this way, the earthen wall has two firepower, but it will not affect each other's attacks, and it can also cooperate with each other to shoot at the same time, increasing each other's attack strength.

"Send a message to Liu Yidong that the auxiliaries behind the Goguryeo shield car are piling up dirt bags in the shield car, and it is likely that they also want to repair the trench." Wang Junlin took down the telescope and said to Zhang Tiangang next to him.

The latter immediately replied, quickly wrote what Wang Junlin said with a charcoal pen, and then sent a message to Liu Yidong with a sea eagle.

Wang Junlin observed from the perspective of the sea where he was located, after two stone bullets hit the shield car, the front guard plate was shattered, revealing the stacked dirt bags inside, and he couldn't help but say: "Yuangai Suwen is not slow to react, and he knows how to learn from us, and he even thinks of building a trench. ”
