The guards of Xiangyi Iron Mine were extremely brave in hand-to-hand combat with the Chu army in order to defend the family's property or to carry out the loyalty in their hearts, and almost every time someone died, they would drag a Chu army to die together! However, the Chu army came prepared this time, and the soldiers dispatched were all the elite of the Zhao clan, and when it came to real combat effectiveness, they were even more powerful than the soldiers under the command of the King of Chu!

Not only did they prepare sufficient defensive weapons, but they also threw an army of no less than 3,000 people into the attack in the Xiangyi Iron Mine alone. In a place like Xiangyi Iron Mine, which has no city walls to defend, how can the bravery of soldiers alone defend against so many elite attacks?

Only half an hour later, the Xiangyi iron mine was completely conquered by the Chu army. More than forty percent of the guards in the iron mine were killed or wounded, and the rest were all captured except for more than 100 people who fought their way out of the encirclement! The soldiers were followed by the workers who operated the machines in the iron mines, as well as the miners who remained underground and still mined.

For this kind of red-eyed battle, according to the rules of this era, the city will be slaughtered! However, Zhao Rat had previously received orders from Zhao Slip to keep the organization system in the iron ore intact, so that they could quickly apply the iron ore. Therefore, as soon as the iron mine was completely occupied, Zhao Rat not only prevented the Chu army from killing prisoners, but even the miners underground wanted to take advantage of the opportunity for the iron mine to change hands to retaliate, but Zhao Rat forcibly stopped it.

When the Xiangyi iron mine was conquered, the simple coal and iron industry established by Dai Yan on the south bank of Suishui was attacked by the Chu state. Coal mines, coking plants and ironworks have all been attacked, and the situation elsewhere is relatively better than the rapid capture of the Xiangyi iron ore mine.

Xiangyi's coal mine is the largest in several organizations on the south bank of Suishui, and the garrison force is also the most abundant, and the importance of coal mines in the eyes of the Zhao clan is far lower than that of iron mines and iron works, so although the army sent by the Zhao clan to attack the coal mine is also quite numerous, but in terms of the elite level is far less than the clan soldiers under Zhao Rat, so although the battle situation here is also extremely fierce, but under the command of the commanders of both sides, it has reached a draw.

The fiercest battlefield was a series of factories on the banks of Suishui. In particular, the ironworks in it were the most important target of the Zhao clan in this war, and this place was personally commanded by Zhao Slip!

However, the defense of this place is far from being comparable to the rudimentary defense facilities of coal mines and iron mines. In order to operate in the area for a long time and improve the living conditions of the workers, Dai Yan built a large number of accommodation quarters around all the factories. These lodging areas are similar to those outside the city of Taoqiuxi, with rows of buildings surrounding all the factories on three sides by the river, thus forming an impregnable walled city!

When the Chu army attacked the Xiangyi iron mine, in addition to the internal alarm, the iron mine also called the external alarm by burning black smoke. When Shogli led his army to the factory area, he was already facing a heavily defended city.

Since you can't launch a surprise attack like Xiangyi Iron Mine, let's attack it directly! Zhao Hua thought silently in his heart, and then, under his order, the siege equipment that the Chu army had already prepared was pushed out one after another, and the Chu army, which had an absolute advantage in numbers, began to attack head-on!

However, once the assault really began, the Chu army soon realized the difficulty of this place.

The three-storey factory dormitory was more than 10 meters high, which was more than the height of most cities in this era. These dormitories are all connected together, and they are no different from facing the city walls.

For such a dormitory wall, Zhao Slip did not rashly attack, he first rushed the closed gate with a rushing car. However, the iron gate does not move at all, and it cannot be broken open in a short time. Later, Zhao Slip used the trebuchet to test the thickness of the wall, only to find that the trebuchet's attack was completely ineffective!

Zhao Slip didn't know that for the outermost wall of the factory dormitory, Dai Yan was indeed planned and designed as the city wall of the city. Although it is not as thick as those earthen walls, it is not as tough as these thick walls.

Unlike the rudimentary bricks used in the earthen city walls, all the walls of the factory dormitory were made of bricks fired at high temperatures, and their hardness and toughness were not comparable to those of the earthen bricks of this era! Moreover, in the wall, Dai Yan even added part of the strip iron rarely, and mixed it with some sand and cement, thus forming a structure similar to the reinforced concrete of later generations!

Although due to the process, the strength of the concrete obtained by this soil method can be far from being compared with the real reinforced concrete in later generations, but this also makes the strength of the entire dormitory exterior wall extremely strong!

And on the outside of this extremely strong wall, Dai Yan also spent a lot of money! In all the exterior walls, Dai Yan used cement to paste the walls. In this way, the entire exterior wall of the dormitory is connected together, and the bricks that were originally visible to the naked eye cannot be seen, and the entire exterior wall is truly integrated! Even if someone wants to climb the city wall with tools, there is no good way to face such a cement wall!

The establishment of such a city wall was not because Dai Yan foresaw that there would be an attack by the Chu army in the future, but because Dai Yan also planned it when he planned the outer wall of Taoqiu. Since a dormitory similar to the one outside Taoqiu West has been established in the industrial zone of Xiangyi, it is better to simply use the experience of Taoqiu City here! I didn't expect his plan to be like this, and it worked wonders at this time!

According to Dai Yan's prediction, with such a solid outer wall, in the era of cold weapons, it is estimated that except for the Tongwan City established with blood, there is no city that can be stronger than it!

In the turmoil of the Sixteen Kingdoms of the Eastern Jin Dynasty in later generations, Helian Bobo, the last leader of the Xiongnu, established Bactria and established a solid city for his kingdom, Tongwancheng. When the city was built, soldiers would follow behind the craftsmen at every step of the city wall, and after the city wall was completed, the overseer would order the soldiers to take out a sharp cone to pierce the city wall, and if the awl pierced an inch, the overseer would kill the craftsman; If you don't stab in, the overseer will kill the soldiers! This kind of city wall built with blood has not fallen for thousands of years, and even in the Northern Song Dynasty, it once became the capital of Western Xia, and even the Mongols suffered a big loss under this city!

Dai Yan asked himself that he could not use such means to build such a high-quality city wall, and compared to defensive operations, he himself believed in the famous war philosophy of later generations - offense is the best defense!

If both the chariot and trebuchet are ineffective for attacking the city, then the only siege machine that can still be used is the ladder.

The ladder is the masterpiece of the former god-level craftsman Lu Ban! Lu Ban served the king of Chu and built many siege equipment for the Chu State, including rushing cars, trebuchets and even ladders are his inventions!

A ladder is a complex piece of machinery that consists of three parts: the bottom is equipped with wheels, which can be moved; The ladder body can be lifted up and down, carried by manpower, and leaned on the city wall; The top of the ladder is equipped with a hook to hook the edge of the city and protect the head of the ladder from being pushed and destroyed by the defenders. Such a siege machine can provide countries with the ability to climb cities, and it is the nemesis of all cities in the world!

Five hundred meters away from the outer wall of the factory dormitory, Zhao stood there steadily. Under his order, the rushing cars that had originally stormed the city gate and the city wall retreated, and stood dozens of meters away from the city wall, and the Chu army standing on the top of the rushing car began to fire arrows one after another, and launched an attack on the Song soldiers standing on the roof of the dormitory.

And the Song soldiers standing on it were not to be outdone, and launched a counterattack with arrows. Compared with the crossbow of the Chu army, the bow and crossbow of the Song army were more complex, faster in rate of fire, and more powerful, and the Chu army standing on the top of the rushing car quickly fell behind!

However, the goal of the Chu army is not to give the other party too much damage through such means, they just hope to harass the other party in this way and provide an opportunity for the cloud ladder to approach!

At this time, standing on the top floor of the city wall to direct the defensive battle was an elite among the disciples of the Mo family-Rong Xuan. Before the Mo family defected to Dai Yan, they went to the world to talk to the princes and advocate "non-attack", and they can have this kind of confidence because they are good at defending the city!

How to deal with the ladder, they have long been experienced! There are three kinds of defensive weapons invented by Mozi, the ballista car, the transfer machine and the car, and the first two of these three types of defense weapons are sharp weapons that fire a large number of crossbow arrows in a short period of time, and the last kind of car is a machine that can project charcoal!

Under the influence of the scientific theories pioneered by Dai Yan, these machines were modified by the disciples of the Mo family, and even Dai Yan was amazed by what they obtained. Dai Yan predicts that if there is still the Han Dynasty and Zhuge Liang in later generations, then the name of Zhuge Repeater will never appear again! In Dai Yan's eyes, the improved repeater has become an instrument that can fire dozens of arrows at one time.

After the ladder of the Chu army approached, the soldiers operating on the ladder were immediately attacked by this kind of crossbow cart, and in a short period of time, the soldiers of the Chu army on the ladder were shot by the Song army! If Dai Yan were to come to this battlefield in person, he would definitely think of some kind of NB weapon in later generations - machine guns!

However, this kind of casualty could not be touched by Zhao Slip in the slightest, and under his order, the cloud ladder began to move again, and the Zhao clan soldiers also followed without fear of death! Compared with the previous casualties, most of the Chu soldiers who climbed the ladder this time had a simple wooden shield in their hands, which made the killing efficiency of the crossbow car begin to decline.

Under such circumstances, Rong ordered the Song army to stop shooting. Under his command, a specially made bed crossbow made by the Divine Crossbow Factory on the castle tower began to operate! This is an enhanced version of the bed crossbow designed by the Divine Crossbow Factory, and it has nearly half the range of the average bed crossbow!

During the time when the Chu army's ladders slowly moved to the city wall, Zhao Slip was not idle, under his precise command, the Chu army moved in an orderly manner, and those ladders advanced step by step, slowly getting closer and closer to the outer wall.

Just when Zhao Slip was concentrating on commanding the Chu army, Rong Yi changed his identity as a commander, and he personally controlled the enhanced version of the bed crossbow and turned himself into a sniper! He wants to kill the general of the Chu army on the opposite side with one blow through precise sniping!

The enhanced version of the bed crossbow requires eight people to help turn the winch, and the only one who controls the bed crossbow and fires this fatal blow is Rong Worm himself! He knew very well that such a sniper might only have one chance to launch in this siege battle, and if he missed it, he would lose this opportunity forever!

With a "bang", the crossbow on the castle tower, which had been silent for a long time, made a sound that was different from all the bowstring sounds! With such a voice, even if Zhao Slip stood five hundred meters away, there was a chill in his heart for no reason, as if he had the illusion of being targeted by a fierce beast! At this moment, he had been able to use his sharp reflexes from years of fighting, and he only had time to fall to the ground on one side of his body, and then he felt a great pain hit him!

And the Rong Worm on the city tower, as well as all the Song soldiers who defended it, were all very happy when they saw the enemy generals fall to the ground!

However, they didn't rejoice for long, but in just a few breaths, the general of the Chu army, who had been shot by the bed crossbow, stood up again. People in the distance, even if they stood in the distance, the people on the city tower could see that the general of the Chu army drew out his saber and waved it directly to his left hand, and the entire left hand was cut off like this!

Then, the general of the Chu army pointed at the city tower with the sword stained with the blood of his body, and the cloud ladder of the Chu army, which had just stopped because he was worried that the lord would be killed, began to move slowly again!

Then, the general of the Chu army began to order someone to bandage his wounds, and he himself began to retreat hundreds of meters. However, he did not retreat to the large camp of the Chu army, or walked off the battlefield, but stood on the top of a high rushing cart, and continued to stand in a place where the soldiers of the Chu army could see and began to command!

As he retreated, one of his guards picked up his left hand, which had been cut off by the bed crossbow. Then the guards followed Zhao Slip's order and personally brought this left hand with crossbow arrows to the front line of the siege, displayed it in front of all the Chu soldiers, and told them: "This is the left hand of Lord Sima, the Song people shamelessly attacked and attacked, Sima hopes that you and others can break through this city and be ashamed!" Master Sima said that even if his left hand was broken, he would still stand on the battlefield and watch the warriors of the Chu State break through this city! ”

The Chu people were a romantic people, and such a people did not pay as much attention to strict order as the Qin and Jin states, which made their armies tend to collapse easily due to poor discipline when fighting against the Qin and the Three Jin. However, the spiritual power of the Chu people is extremely powerful, and when they are stimulated, they can burst out with a power that the world can't imagine!

After Qin destroyed the Six Kingdoms in later generations, although Chu had three households, the death of Qin would be Chu, which was the embodiment of this spiritual power! And Xiang Yu is in Julu, breaking the cauldron and sinking the boat, which is also the explosion of the spiritual power of the Chu people!

And the main general was shot off his left hand by the enemy on the battlefield, which is a great shame for all the Chu soldiers on the battlefield! And this kind of shame, in the eyes of the Chu people, must be washed away with the blood of the other party!

Under such a strong will, the Chu people immediately became fearless of death! The ladder, which had been moving slowly, suddenly increased in speed and soon reached the bottom of the city wall. When the ladder reached the city tower, the Chu army, whose morale was amazing, rushed up to the city tower through the ladder regardless of the intention of killing and wounding!

Under such a swift attack, the castle tower immediately became precarious!
