The sound of cannons was the sound of cannons, and even the Jurchens seemed to be used to it. The only thing they didn't get used to was that two or three miles away, the projectile could explode the human body and fall to the ground.

The shouts of the Jurchens, whimpera, originated from the shouts of driving away prey during hunting.

After a moment, all fifty cannons broke out, and the projectiles hit more than 30,000 iron armor, which was very powerful. This is the power that the cannon in Zheng Zhi's impression should have.

"Transfer the order, put up the cannon barrel, put on iron sand, and bang hard!" Zheng Zhi ordered the cannon again.

Use projectiles from far away, and use iron sand near. Iron sand was also brought by Ling Zhen from Hejian Mansion in the first few days. Although the range of iron sand is not far, it can cause large-scale damage. It is the most suitable for dealing with the Jurchens who are sieging like this.

If the iron sand is placed in a musket, the power it will be even greater. Countless iron sands are placed in large caliber gun barrels, and the power will be much smaller. Facing the Jurchen iron armor, whether it can be broken depends on luck.

The reason is that the airtightness of the barrel is different. The projectile can block the entire barrel, and the energy of gunpowder can be almost all applied to the projectile. Iron sand cannot block all barrels. It also needs to be stuffed with a ball of paper or straw, and then stuffed with iron sand. Even so, the energy of gunpowder will be wasted a lot.

Fortunately, iron sand gushed out on a large scale. Even if many places with heavy iron armor cannot be broken, there are many places with thin iron armor, or on the face, it is easy to kill people's lives.

Arrows are like rain, and arrows are always like rain. The arrows like rain are the basics of the real battle formation.

The long ladder has hooks, tightly stuck on the merceration.

The soldiers on the mercedes picked up a big knife and went to cut off the janitors above the long ladder with hooks. The stones kept tilting downwards to block the climbing Jurchens.

After the locket of the long ladder was cut off, the iron hook could no longer hold the long ladder. Then several powerful soldiers used two feet long tree branches to support the long ladder and pushed them outward.

Only in this way can we truly push down the long ladder. With human hands, we obviously cannot shake these long ladders in the slightest. People are climbing up the long ladder, and only by using tools can we push the long ladder out of the long ladder with the help of tools.

Both sides are familiar with the way of offense and defense.

The burning excrement has a good name called gold juice. In fact, this name comes from traditional Chinese medicine. There is a traditional Chinese medicine made of excrement and red clay, which is the name.

The burns caused by boiling excrement on people are just one of the reasons, and the infection of the wound is the untreatable thing in this era.

The hot oil becomes extremely flammable, and as long as a little spark is a blazing fire.

Zheng Zhi saw too many of these scenes and had no feelings for him, and he would not even frown.

Nianhan stood under the city, and today's battle could not be divided into any generals. The Jurchen clan, except Wanyan Wu Qimai, could die, and everyone needed to die on the battlefield.

After climbing up the long ladder, climbing up quickly, avoiding a few stones, Nianhan finally fell down, and then stood up again. The long ladder had fallen and hurriedly went to help.

Niu Da stared at the air with his eyes tightly. The flying feather arrows had obvious trajectories in the air, which allowed Niu Da to raise the wooden shield from time to time to resist the wandering arrow for Zheng Zhi.

The simple catapult cart was also pushed up by the Jurchens. The stones were thrown onto the top of the city, which would inevitably cause blood to burst into pieces.

The strength of the crossbow can allow huge arrows to penetrate directly into the brick and earth city wall, and it seems to help the Jurchens climb the city wall.

"Live, add five thousand people." Zheng Zhi issued an orderly order.

Under the urn city, five thousand people rushed up to replenish the defense on the city. A military man, before he could approach the battlement in front of the city, had not seen the Jurchens under the city, had been shot into the door by feather arrows, and fell to the ground and wailed.

Then two people carried him down the city wall, and someone came to pick him up. He carried the wounded to the foot of the city wall on the other side, and the medical officers were waiting there.

A black shadow came straight from the bottom of the city, Zheng Zhi, who was sitting firmly. Niu Big eyes were quick and fast, and quickly raised the huge wooden shield to block it.

Even with this block, Niu Da had already fallen at Zheng Zhi's feet with an explosion. The wooden shield was also split into pieces.

Zheng Zhi hurriedly leaned over to support Niu Da.

"Prince, I'm fine, but my arms are numb, maybe my bones are cracked. The Jurchen dog's stone throwing cart is really accurate." Niu Da jumped up before Zheng Zhi could help him, and said.

Zheng Zhi nodded: "Niu Da, you go down the city first to find a military doctor."

Niu Da wanted to shake his arm, but found that his arm was out of control and nodded: "Prince, I'll go down and come up in a moment."

Niu Da turned around and left, and then several wooden shields blocked Zheng Zhi. There was only a shield in front of Zheng Zhizheng's head, and it was already four shields.

The battle of siege seems extremely monotonous, and the methods of siege are mostly similar.

Wanyan Wu Qimai was no longer sitting upright on the platform, paced back and forth, his face was anxious, and his heart was beating wildly. This emperor who had just ascended the throne should have entered the Central Plains, forged unparalleled achievements, and forged the century-old Jin Empire, from grasslands to forests, from outside the pass to Yanyun, from Hebei to northwest.

At this time, Wanyan Wu Qimai knew that his empire had reached the point of life and death. If he could not continue this step today, he would be doomed.

Wanyan Wu Qimai didn't have the face to see his elder brother Wanyan Aguda, the hero who led his clan members out of the forest and destroyed the Great Liao Dynasty.

At this moment, Wu Qimai was still thinking in his mind that if his elder brother Aguda was still alive, would there be a better way or a better way? Instead of constantly consuming the few tribe members in this way.

If Olibubububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububububu

At this time, the two sides should still be in a stalemate. It seems that everything will not reach this point.

Wu Qimai probably regretted it a little.

Of course, everything can be thought of the opposite. If Olibu directly breaks the barrier, it will be a different situation at this time.

Things in the world always touch the whole body in this way. If Master Zhong was not dead, Lu Da did not rush to go south, nor did Zheng Zhi go south. This war could not be started at this time. There were not so many ifs, everything was a coincidence by fate.

It seems that God has long been destined.

The Gubei Pass, which was destined to use all its resources to defend, cannot be defeated by the Jurchens.

The Jurchens cannot break this barrier, not Zheng Zhi’s current defense. It is because Zheng Zhi’s many years of planning. Over the years, Zheng Zhi has been waiting for this moment and making all the preparations for this moment.

Countless iron armor, strong bows, crossbows, and large and large artillery. Even Zheng Zhi was in Xiongzhou at that time, regardless of even and desperately, he was determined to cross the Juma River at the first time and went straight to Yanyun to start a war with the Liao Kingdom. It was also for this moment and for the long-abandoned Great Wall Pass.

In order to control the defense line north of Yanyun, the whole family was almost taken hostage by Cai You.

Zheng Zhi has been preparing for the war with the Jurchens, and even everything is more or less about it. The Jurchens never really took Zheng Zhi seriously until the battle on the grassland.

Today, the Jurchens obviously cannot get up to the front of the ancient north city.

This is also why Zheng Zhi was able to sit upright on the city wall, rather than paced anxiously like Wanyan Wu Qimai.

In Wu Qimai's vision, only Jurchens fell down from the long ladder. At this time, Zheng Zhishou's Gubei Pass was obviously a world of difference from Shi Jin's defense.

Wuli could not attack the city because most of Shi's army were Cangzhou soldiers, and the arrows in the army were used up, and the rolling stones of the wood were not ready.

Today, Zheng Zhishou’s pass was prepared for everything. Even the most elite soldiers were at the pass.

On the platform, there was a seriously injured Wu Libu sitting, and a Wu Qimai who was walking non-stop.

"Your Majesty, I'm afraid that this will not work. I still have to let the Goryeo consume Song Gou's feather arrows first. Only when the Goryeo dies will I, the Jurchen warrior, work in one blow." Olibu naturally discovered something was wrong, and this battle should not be fought like this.

Wu Qimai stopped hearing this: "Goryeo? Will the Goryeo go up the day before yesterday work? The Goryeo we killed ourselves the day before yesterday is no less than Zheng Zhi killed."

"Your Majesty, even so, the Goryeo people should die first. Song Gou's arrows can consume as much as they can." O Libu replied.

When Wu Qimai heard this, he did not answer the words. He walked a few more steps and said, "How about withdrawing troops at this time?"

When Wu Li heard this, his eyes were dumbfounded: "Retreat troops? Your Majesty, how can we withdraw troops at this time... After withdrawing troops, I'm afraid..."

Wu Libu obviously understands the truth.

Wu Qimai suddenly became a little firmer and said, "I withdrew my troops and led Zheng Zhi out of the pass to chase him. In this way, we will fight with the cavalry."

When Oli Bu heard this, his eyes lit up. He thought for a moment and replied, "Your Majesty's method... is recommended to do it."

It's a bit better than this battle situation.

Wu Qimai already shouted: "Sing the gold, quickly sound the gold."

Even Wu Qimai could no longer bear the elites of the Jurchens falling down from the long ladder one by one. It was really meaningless to consume such a thing.

A masterpiece of gold roaring!

The Jurchens who were still gritting their teeth and rushing to the city wall looked north with confusion on their faces. When the sound of gold sounded particularly sincerely, they turned around and began to retreat.

Even the Jurchens have never fought like this since they started their army.

The tide comes and the tide goes.

Shi Jin rushed to Zheng Zhi, looked overjoyed, and shouted, "Prince, the Jurchen dog is defeated."

At this time, Zheng Zhi's face, which had been serious, finally calmed down and said, "Wu Qimai is really decisive."

Looking further away, soldiers of the Jurchen camp had already begun to board the horse.

Then more and more soldiers began to get on the horse. The camp was in chaos. Even the Koreans were released and a large number of sheep were driven out of the circle.

"Prince, this Jurchen dog is going to run away?" Shi Jin saw the Jurchen plan at a glance.

At this time, Wu Yong, who heard the sound of gold, also rushed to the top of the city, looked north for a moment, and said, "Your Highness, the Jurchens are really going to run away."
