This improvised equipment is also a simple copycat version, with two wheels and a long thick plank, and there are bags of earth and stones piled on top, which can be directly erected on the trench for shield carts and soldiers to pass, and the piled earth and stone bags are used to place arrows and fill in the trenches, so that the soldiers who set up the carts in the trench can have a foothold.

Under the coercion of Wang Junlin's soldiers, the captive auxiliaries of the cart desperately threw the earth and stone bags into the trench, which was only more than 20 steps away from the city wall, and the long-range troops on both sides fought more fiercely. Constantly the captive auxiliaries who filled the trenches were shot and fell to the ground wailing loudly.

Goguryeo bows and arrows are generally shot like crazy, the body is all full of arrows, there are constantly soldiers on the side of Wang Junlin falling, the Sui army's continuous fast crossbow cover is also very violent, they fire a salvo according to the unit, and quickly overwhelm the bows and arrows of the Goguryeo people in terms of rate of fire, the Goguryeo people except for the first round of salvo fire, the back shots are very scattered, and the interval is getting longer and longer.

At this time, the giant stone throwing machine on Wang Junlin's side fired stone bullets on both sides of the city, and the Goguryeo soldiers had a long bow drawing and aiming process when shooting arrows. The bow and arrow did not pose the slightest threat to the shield chariot, and the Goguryeo archers fell in such a covered duel.

The Sui army had two small, finely crafted stone throwers that were pushed up with the shield carts, but they were never launched, and they stopped by the moat facing the gate, sandwiched between three sturdy shield carts.

At one point, an ingenious stone thrower on the left fired not a stone projectile, but a fusing bag of explosives.

"Boom!"

With a roar, the wooden gate of Daluo City shook violently like papier-mâché, making an ugly rattling sound, and a huge hole was blown out of the door.

"Another catapult is ready to be fired at any time, but don't rush to throw the explosive pack." The lieutenant in charge of the front-line command took a look at it, retracted and said to the rock-throwing crew on the right, "There is no earth-filled stone behind that gate, and the Goguryeo people may run out." Trebuchet No. 1 continued to throw explosives packets, blowing up the door for me. ”

The No. 1 trebuchet on the left threw out another explosive bag, and after a loud bang, the left door leaf collapsed, and the right door leaf also tilted crookedly, revealing the black door hole, and there were several corpses on the ground, and the backs of more than a dozen Goguryeo soldiers desperately fled backwards, and after getting out of the door hole, they hid left and right behind the city wall. Then there were many people who looked like Goguryeo auxiliaries and desperately piled stones on the streets.

At this time, the king in front of the city gate forced the prisoner auxiliary soldiers to throw down the earth and stone bags, and then pushed the trench cart down, and the front section of the trench cart fell into the trench, splashing a large splash.

The soldiers on Wang's side forced the Goguryeo captive auxiliaries to jump into the trench, and they stepped on the earth and stone bags below, removed the wheels of the trench carts, and then lifted the planks to the edge of the trench on the opposite side.

Under the cover of the moats, the bows and arrows at the head of the city could not reach them, but the soldiers on the side of the king shouted and cursed, urging them to set up as soon as possible. These panicked auxiliaries desperately held the planks and erected the edge of the trench one by one.

"The two-winged shield car is ready to cross the trench!" The voice of Lu Han, who was in charge of sniping at the city gate with the main force, came: "The explosives package is coming a few times towards the roots of the two wing walls, and the auxiliary soldiers are easy to dig up." ”

The commander of the front line muttered: "The city gates have been blown up, why don't you attack the city gates immediately?" ”

A hundred-man commander next to him shook his head and said, "Just now, the infantry on both sides also received an order, saying not to rush in, there may be how many Goguryeo people are in the city gate, from a gate hole on that side, we can be attacked all around, and there are bows and arrows on our heads." Dig both sides of the city gate first, and you can see clearly when you dig it down. ”

As the two spoke, the ingenious stone thrower immediately turned around and threw an explosive bag at the wall next to it, blasting the masonry there.

A moment later, a military horn sounded, and the two-winged shield carts began to cross the river one by one, each car followed by a hundred-man infantryman, and the continuous crossbow attacks in the back row became more violent, and the Goguryeo soldiers at the head of the wall screamed again and again, and the counterattack gradually weakened.

The shield cart stopped a few steps away from the city wall, several triangular roof carts were directly on the city wall, and the auxiliaries below began to dig the roots of the wall under the supervision of the Sui soldiers who followed.

There was a burst of scolding at the head of the city, and there were no rope control weapons such as yaksha slapping in the position of several chariots, and the Goguryeo soldiers quickly threw down stones one after another, smashing them on the chariot with a bang, and the top of the chariot was triangular, which had the effect of unloading the stone and wood, and similar pointed wooden donkeys and hook crash cars were of this shape.

The captive auxiliaries in the cart were very nervous, they could hear the movement on the roof of the car, this cart was made by the craftsmen of Wang Junlin's side with the army to guide them to work, these captive auxiliaries had no bottom in their hearts, they dug desperately with shovels and shovels, and after taking out the bricks and stones that were loosened by the explosives bag, they began to dig the rammed earth inside, these rammed earth are old for a long time, and the part that has been eroded by the rain of brick joints on the periphery is better to excavate, and the inside has already been pressed very tightly, and a shovel can only dig a small piece.

Wang Junlin rode on the bloodmane horse and looked under the city wall from a distance, and it took a while for a little dirt to be thrown out, and he couldn't help but say to Zhang Tiangang: "The excavation speed is a little slow!" ”

"They don't seem to be digging in the right place, I'm afraid the soil is going to be harder. I think those Goguryeo auxiliaries are also afraid at this time, and they will never delay time. ”

Wang Junlin raised the binoculars again, observed for a while, and said: "Go back and ask Lu Han and Guan Xiaotong's troops to make a training syllabus for gunpowder blasting, the explosives package thrown by a catapult is very limited, and it is not a way to use the captured auxiliaries of the Goguryeo people every time......

Before Wang Junlin finished speaking, there was a shout of killing at the south gate, and Wang Junlin stopped silent,

Hurriedly looked towards the south gate.

Piles of firewood and grass were thrown down from the wall, smashed on the triangular backs of the two chariots, and then slid down to the sides and piled up, all of them fell on the firewood and grass, and someone risked death to probe and poured down a kind of tung oil-like thing, and then several torches were thrown down, and the firewood and grass were suddenly blazing, and several burning people rushed out from under a chariot, and they kept rolling and neighing on the ground.

Lu Han, who was in charge of attacking the city gate, ignored those howls, kept his eyes on the location of the city gate hole, and ordered: "Pass the order, pay attention to the city gate hole." ”

As soon as Lu Han conveyed the order, many archers appeared at the entrance of the city at the same time, and fired a fierce salvo at the shield cart under the city, and several unprepared Wang Junlin's side was hit and fell to the ground, and some powerful Goguryeo soldiers threw the ash bottle far away and smashed it on the shield cart that crossed the trench, and suddenly lime powder splashed everywhere, and several captive auxiliaries whose eyes were fascinated covered their faces and rolled on the ground.
