The Jin army's shield chariot array slowly advanced, and at the same time, a large number of slave soldiers and traitor soldiers continued to spit out from behind, filling in the dense small pits on the ground with dirt bags and removing scattered obstacles such as deer rocks.

A qualified Golden Army Shield is capable of defending against all previously known ranged weapons, including the Eight Bull Crossbow and the Human-Powered Trebuchet.

More than ten years ago, the Zhou army was completely at a loss for this tactic, and was often approached to a distance of ten steps by the shield car, and then it was directly shot by heavy arrows, and then it would be ruthlessly pursued by the Jurchen cavalry.

The entire army of tens of thousands and tens of thousands of times in the Great Zhou was almost all defeated by this tactical hand.

Now the Jurchens are sacrificing this tactic again.

In Xu Shiyang's view, the biggest disadvantage of the heavy arrow tactics of the shield car is speed, the heavy shield car is extremely inconvenient to move, and it is easy to be blocked by small pits, stones or other obstacles, at this time, the huge and inconvenient shield car will become a big target for artillery.

If the artillery of the new army grows stronger in a few more years, this tactic is to send it to death.

But now, Qingzhou only has a small number of copper field guns, as well as dozens of divine machine guns that fire two-pound small shells.

The latter is very far behind in range and power due to the problem of air tightness, and it is difficult to kill a qualified heavy shield vehicle with one hit.

What's more, now there is not a single field artillery on the second line of defense in Qingzhou, because the defenders here are all militiamen!

The militia was even more lacking in long-range weapons, so they could only wait for the enemy to approach slowly.

So far, the ground has formed the biggest obstacle to the Jin army's attack, especially the dense and winding communication trenches between the first and second breastwork, which cannot be filled without filling them.

And the Qingzhou army mobilized 100,000 migrant workers and spent a lot of time digging up the fortifications, so it was unrealistic for the Jurchen slaves and traitors to fill up in a short time.

The atmosphere on the battlefield became very eerie, the defenders did not fire at all, just quietly waited for the enemy to approach, and the attackers advanced as slowly as a turtle, and the two sides kept approaching, but except for a few Jin stragglers who stepped forward and shot some light arrows, the two sides almost did not fight at all.

By night, the Tartars had only advanced about 200 paces from the second breastwork.

The Jin army had to start setting up camp with shield carts, and the first day of the attack was wasted on earthwork.

……

Nighttime.

The battlefield was still quiet, and there was a huge fire every other section behind the chest wall defense line of the Qingzhou soldiers, and some militiamen were baking the cakes sent from behind the fire.

There were also a lot of torches stuck in the breastwork, which illuminated the trench in front of them to prevent the Tartars from sneaking up.

However, just ten paces away from the trench, some of the most courageous warriors of the Jin army, Ulu, and hundreds of other companions lurked quietly.

The wolf-like eyes of the Ulu were fixed on the breastwork not far away, and every once in a while, someone stuck their heads out to look this way.

The vigilance of the Qingzhou thieves is obviously very high.

But it's not enough!

Uru licked his lips and a grim smile appeared on his face.

Bo Ji Lie Wan Yan Zongbi ordered hundreds of them armor soldiers who could travel at night to sneak attack the chest wall in front of them at night—although the shield car array would definitely be able to form a breakthrough, it was too much of a waste of time.

If the night raid can be won at a small cost, then it is certainly worth a try.

As for the shield cart, it will not be wasted on the few earthen walls in the back.

Today's momentum of the shield car formation's slow advance gave several Qingzhou Army commanders on the front line a false impression that the Jin army wanted to use this tactic to advance all the way to the edge of the Yellow River.

Therefore, many people are a little relaxed at this time, and they estimate that the Tartar will have half a day to reach the chest wall tomorrow, and then it will be the real time to fight.

This gave Ulu and his companions a great opportunity.

Another militiaman, as he did, stuck his head out from the top of the breastwork, and glanced at it by the firelight, but he saw nothing, and shrank back again.

According to Ulu's observations, the next time someone sticks their heads out to observe, it will probably be 20 breaths later.

The Jurchen brand leader (fifty households) waved his hand behind him, and more than a dozen armored soldiers hidden in the darkness suddenly got up, carried several short ladders, and quickly rushed towards the chest wall that was close at hand.

Soldier Armor approached the trench in front of the breastwork, carefully placing a ladder covered with thick cloth on the top of the breastwork.......

At this moment, the face of a Qingzhou militiaman suddenly appeared behind the breastwork, and the young man seemed to be resting behind this wall, probably hearing something, so he leaked his head to take a look.

He saw the ladder in the trench, and the cold glittering eyes of the tartars!

"Tartar!"

The sound of terror seemed so harsh in the quiet of the night, but it was only half heard.

The Ulu, who had excellent night vision, raised his hand and shot an arrow, right in front of the man.

"Attack!"

Woo~~~!

Several Mouke, who were in charge of directing the offensive, blew the conch horn at the same time, and hundreds of elite Jin Army armor soldiers shouted in unison, and swooped down several long ladders behind the chest wall!

The fastest of them all was the Ulu, who wore only a leather armor and carried a light waist knife in his hand, and it took only two or three breaths to step over the long ladder, and then leap to his feet, jumping over the low breastwork, and into the trench behind!

There happened to be a Qingzhou militia over there, and the strong Ulu who was like a bear pressed him directly under him, and the thin militiaman screamed miserably, his ribs were broken, and a large amount of blood clots spit out from his mouth, and he was no longer alive.

Ignoring the enemy at his feet, and after falling into the trench, he quickly turned around and swung his sword to the left side of the trench, a militiaman with a spear stabbed straight at him, and the Urus quickly flashed sideways to avoid the deadly tip of the spear.

In a place like a trench, where the spear had only one chance to attack, the Ulu swooped down and plucked off his opponent's head with horror and despair.

"Kill the Tartars!"

Seven or eight militiamen poured out from the bend in the trench in front of them, and they did not flinch to meet the Tartars.

Urum was silent, and with his left hand, he skillfully pulled out a flying axe from his waist, raised his hand and threw it out, hitting the chest of a militiaman holding an axe, and then three or four Jurchen armor soldiers jumped out of the heads of those militiamen, and as soon as they got close, they slashed and smashed with short weapons such as maces and one-handed axes, and the bloody qi quickly filled the trench.

In this sudden white-knuckle battle, the militia was no match for the Jurchen hunters at all, and in a very short time, nearly two hundred golden soldiers crossed the second breastwork, and they quickly controlled a breakthrough of about twenty meters, and some even spread to the rear along the communication trenches.

In this battle, the largest night battle broke out!
