No material is assured that Sima Jilai is assured. Fortunately, there is no shortage of iron ore in Youzhou. Since this is the case, we must give full play to the superiority of the feudal system and increase the output by squeezing manpower, and the effect is very significant.

As the most important raw material for the industrial revolution in later generations, coal and iron were also present in the western suburbs of Jicheng. Otherwise, how could Jicheng in later generations become the foot of the emperor? The geographical location and the resources contained in later generations were really superior. With the same ability as the King of Coal and Iron, there was no ability to guide the industrial revolution, just like he did not turn the steam ball into a real steam engine.

But it still has the ability to play a role in the times. For example, now! The cities in the Jin Dynasty were not the brick and stone structures in TV series, but became mainstream after the Southern Song Dynasty. The resistance of the rammed earth city wall to catapults is actually greater than that of the brick and stone city wall. In theory, the catapult does not play a very big role in front of a city wall like Yecheng, assuming that it is someone else's catapult.

It is not the King of Yan's trenches! In front of the trenches on all sides of Yecheng, trenches have been assembled, and there are a bunch of great tree stumps next to them to serve as ammunition for the trenches. Among these trenches after the siege, wooden barrels are filled with kerosene unloaded from the warship, and are carefully transferred to the trenches closest to the trenches.

The old saying goes, water and fire are ruthless. Just this river that can barely move, imitating Bai Qi and flood Chudu, and not allowing Wu'anjun to be beautiful in the past, should be very difficult. Since that's the case, use fire. In early spring, trees are pulp-filled, and the trunks that have just been cut down are extremely difficult. Sima Ji had only had a life experience in black soil and had a try-taking attitude. He was not surprised at first sight. The North China Plain was the same, and the natural laws of the King of Yan could not do anything. Fortunately, he brought kerosene to him.

At an absolute safe distance, Sima Ji held a telescope and looked at the direction of the trencher and said, Sima Yong, do you know that I will spend more money on this king? How much copper coins can this coal tar be sold? Not to mention burning my king's warehouse several times.

Sima Ji really wanted to apply coal tar in many aspects, but he has never succeeded. The oil in the kerosene lamp sold in Jicheng is not such a dangerous coal tar at all. In addition to the fact that a layer of glass is not easy to blow out, it is still the original material.

Now it seems that only setting fire is more useful, and it just happens that you can try whether the by-products of important industrial raw materials are useful in Yecheng.

The abnormal movements of the army outside the city made the defenders suddenly alert and called Lu Lang, who was responsible for defending Yecheng. Lu Lang climbed to the top of the city and saw a catapult. The enemy soldiers holding flags had already climbed onto the high platform of the architecture. This was the prelude to the siege.

The Yan thieves were about to attack the city, and they ordered the entire army to be careful when they responded. The Yan thieves were cruel and bloodthirsty, and the people were in the city. Lu Lang shouted loudly, asking the soldiers on the top of the city to prepare for the fight.

As for whether this statement is useful, Lu Lang was actually unsure. The surrendered soldiers under the city have been calling for surrender every day for many days, and the soldiers on the front of the city have also listened for many days. If Lu Lang had not been watching it tightly, he said that the surrendered soldiers under the city were just pretending to be the soldiers in Yecheng who were caught by Sima Ji, most of the soldiers in Yecheng had been massacred, and the defenders had already been panicked.

This is why Sima Ji never cared about fame. It was not that he had to take a false notorie, but that he knew that what others liked to spread the most was his notoriety. If the result was the same, it would be better to spread it yourself. In the eyes of the defenders of Yecheng, the King of Yan was a man who was slaughtered by the world alone, and this was the result of his blockade of news. He didn't know what his notoriety would be like even further away.

Apply oil the stump, put it on the trencher, and ignite it. The leader who was responsible for the trencher shouted loudly and directed his subordinates to complete the final steps. Boom! The stump covered with coal tar burned in the trencher, causing a burning sensation on everyone's face.

Let it go! With a command, the big catapult's arm began to fall down again and again under the neat pull of more than ten strong soldiers, and then raised it. The stumps of cow-sized heads placed at the rear end roared into the air, and threw them far away towards the city opposite with burning flames and elongated smoke.

In early spring, trees were pulped with water. The weight was slightly lighter than stones, but the power was not light at all. The power of casting stones was very great. The power of casting wooden pier was not small. The wooden pier covered with coal tar hit the head of Yecheng City, and more of them skipped the head of the city and smashed into the city. Wherever they smashed, the battlements made of clay were smashed into pieces. The soldiers standing behind the battlements were smashed into pieces, burning the unburned viscous coal tar on their bodies, crying heart-wrenchingly, cursing the swallow thief they said that they would not die well.

It must be said that your father is still very blessed by God. These things were originally intended to be used on the head of Handan City, who would not use them? Sima Ji hugged Wang Shaoyi's young body and put the telescope in front of the little lady's eyes. While he was speaking, the body of a soldier in Yecheng was hit by a wooden pier. Blood was spit out of the corner of his mouth. After the flames on his chest disappeared into the battlements, the fate was predictable. The soldiers in the Longque Camp were afraid of heavy blunt objects, let alone the flesh and blood body was directly hit by the wooden pier of the catapult. What does it mean to burn all five inside? That's it.

I, I dare not look at it. Wang Shaoyi closed her eyes and avoided the scene in the telescope, and her tender face flashed with unbearable help.

He is not the same as Yang Xin! Sima Ji thought to himself and took away the telescope in front of the girl. If Yang Xin was by her side, he would be happily following the couple with the King of Yan. But this is also a good thing. Ordinary people like Yang Xin can't afford to eat or bear another woman.

I was wrong for my husband, go back to the camp! Sima Ji comforted Mrs. Xiao Wang quietly, saying that this test was a little bit unfamiliar.

Just as Sima Ji said, Wang Jun, who was also looking out from afar, swallowed a hard spit. Fortunately, he made a quick decision and was worthy of his shrewdness and courage as he had been practicing as an official for many years, and surrendered without hesitation. Otherwise, these things would not be Sima Yong, but him. Thinking of this, Wang Jun suddenly breathed a sigh of relief for no reason, feeling like he had a life after a disaster.

Throw all the wooden piers! The head of the catapults who were responsible for each snatching machine shouted loudly, and the soldiers threw out all the prepared wooden piers. No matter what the situation at the head of Yecheng City, they would not suffer heavy losses, even if there was no one above, they would only complete their own work and others would be responsible for the siege.

Most of the wooden piers did not hit the tall city walls of Yecheng, but were directly thrown into the city after they crossed the city walls. In ancient China, the main reason for wooden houses was that once there was a fire in the city, the consequences of Sima Ji was unimaginable. This time, Sima Ji was more experienced than when he besieged the domestic city of Goguryeo many years ago, with complete materials and the range of the trencher increased.

The fire at the city gate affected the fish in the pond. If the people in the city were inconceivable, the consequences would be unimaginable, and the morale of the soldiers guarding the city would definitely affect the morale of the soldiers guarding the city. Lu Lang, who was keenly discovered the long-range shooting of the Yan thief, had just seen a fire in a house, and immediately ordered the soldiers to suppress it. However, the fire on the Yecheng Tower burned, and he could not save it.

The defenders of Yecheng were attacked by the fire of the catapults, causing a rush. The catapults of the attacking team on the other side were still operating. The King of Yan said that it was too big, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, that is, to be, not food. This set of imperialist rhetoric, that requires cannons, butter, has been deeply involved in the minds of the soldiers under his command, and these soldiers are now practicing.

Just as the ammunition of the catapult reached the bottom, the flags of dozens of high platforms pressed down fiercely, which was a signal of siege. In an instant, countless soldiers in the trenches around Yecheng carried swords and shields and rushed towards Yecheng like huge waves.

At this moment, when he was officially making achievements! Wang Zhuo, who had just been appointed as the chief general of the former army, drew out his sword and shouted loudly at Yecheng, with a very passionate expression, and decided to make achievements for his brother-in-law.

Carrying hundreds of large wooden shields, they were quickly placed in front of the army, forming a barrier, and thousands of archers emerged from behind the shield. While advancing with the shield, they began to draw bows and arrows at the top of the city, suppressing the Yecheng defenders who were knocked and turned toward each other, and also opened up space for the soldiers behind to rush out of the trenches.

Blasts of black arrow rain flew out of the formation and flew towards the city. In fact, at the current distance, the cluster of arrows shot had no effect on the defenders above, but it was indeed a good way to disrupt it. The sound of messy steps and the sound of arrows breaking through the air.

As the formation shot wildly, countless siege soldiers who were pulling the cloud ladder rushed out of the trench and ran straight towards the city wall. The siege ladder was dragged toward the city wall quickly. Many soldiers were carrying cloth bags of soil on their backs. As for where the soil came from, they were dug into spiders outside Yecheng, which was a remains of the trench.

Under the education of the soldiers of Youzhou for many days, the surrendered soldiers understood what it means to enforce orders. They would never act without orders and dared to disobey the battlefield. There was also a supervising team wearing red clothes behind them. So it seemed that there was no formation to attack the city, but these soldiers who rushed out of the trenches were not in chaos at all. If they were in chaos, they would not die in front of the formation, and the same would be true for death by military law.

A large number of light-armed soldiers flew past the giant shield archers who were covering the cloud ladder and rope hooks.

Soon, the soldiers who used cloud ladders to fill the city with various means rushed across the moat. The sound of cloud ladders being against the city wall came from the city wall. The defenders on Yecheng City walls got rid of the threat of stone-capping machines and also pulled their bows and shot arrows, killing their comrades who were the same camp just a month ago.
