If you want to change people's concepts in this era, you can only spend a long time to imperceptibly, and it is absolutely impossible to achieve it overnight. Therefore, it seems that more efforts need to be made in ideological work. However, what Feng Huaidao said gave Gongsun Jian a reminder that the new policy was actually to shake the rule of those wealthy families from the foundation. Even those Zhou nobles who had been standing behind them did not want Gongsun Jian to win in the end, but only used him to contain and fight against the Zhou royal family.

With that in mind, the rest is easy. Hu Tianyi was asked to find Hu Tianyi and then personally instructed Hu Tianyi's security department to strengthen the monitoring of internal personnel, not only to prevent the enemy's investigation of its own intelligence, but especially to understand the ideological dynamics and purity of internal personnel. Anyone who finds that his mind is wrong must act in time, no one can sabotage the implementation of the new policy in the area ruled by Gongsun Jian, and those who resist and sabotage whether openly or secretly will be executed. In addition, Feng Huaidao, Huang Wenyuan and others should also strengthen the education and screening of local officials. Gongsun Jian sent Feng Huaidao to go back first. After all, this is the front line, and a big war is about to begin. And Feng Huaidao's function is to handle other affairs for him in the rear.

Send Feng Huaidao away here, and Sun Sheng's army over there has also arrived. The two armies began a formal confrontation. What made Sun Sheng a little incomprehensible was that Gongsun Jian did not place the battlefield in Linshui County, where the city was stronger, but directly wanted to fight with himself in Dingxi County. Obviously, the purpose is not to lose an inch of land, and at the same time, it is not willing to destroy the good situation of the three northwestern provinces today. It's just that the more than 10,000 people of Gongsun Jian can really resist the army of nearly 80,000 under his command?

According to the information he has, Gongsun Jian now has at least 30,000 people under his command, and he is scattered outside the Seven Prefectures in his current sphere of influence, and there should be at least 20,000 people here, so where did Ding Feng's Fourth Division, which disappeared for a long time without news, go?

Sun Sheng sat alone in his handsome tent and analyzed the information in his hand, and the more he thought about it, the more he felt that Gongsun Jian was cheating. But even if there is a hidden, what can the more than 5,000 people of Ding Feng's Fourth Division do? Sneak attack on your own town far away? No way. Attacking their own rear army with heavy grain and grass? It's too wasteful, and besides, this place is so close to the town far pass, there is no chance for him to sneak attack.

After some analysis, Sun Sheng was always puzzled. So he ordered the generals to be summoned for a meeting to study. In the end, no unified conclusion was reached. Therefore, he simply maintained the vigilance he should have, set aside the necessary manpower to defend the camp and the back road, and at the same time sent people back to the town to ask for a stronger guard. The rest of the manpower was all devoted to the attack on Dingxi County, and they must fight down, and never give Gongsun Jian a chance to play tricks.

In the next day, the Wu army left the camp as a whole, with 30,000 people in the front army as the main attack, and 20,000 people in the rear army as a reserve to support the battle at any time. In addition, he promised to stay behind 30,000 people to prevent the destruction of grain and grass by Gongsun Jian.

The battle began as soon as it began, and there was almost no tentative attack, and the 30,000 and 55 armies rushed towards the not tall city wall of Dingxi County like a tide. Seeing the enemy coming up, he launched a full-scale charge. The soldiers at the head of Dingxi County were also prepared, and a small trebuchet was set up almost every five zhang away.

The trebuchet is not large, but it is lightweight, compact and easy to operate. They can be controlled in groups of three, and instead of heavy stones, they throw packs of explosives that have been prepared for a long time. Each explosive bag weighs about 15 catties and can be easily delivered to a distance of 300 meters, and the explosives package is calculated with the length of the lead, and basically more than 70% of it can explode in the air when it is about to land. The large number of steel balls and iron pieces filled with it are extremely lethal. This is also the reason why Gongsun Jian has the courage and the number of Wu troops far outnumbered him. However, Gongsun Jian did not have such an 'advanced' weapon in his hands. The mines that had been laid outside the city for a long time, and the crossbows on the walls were all powerful weapons for defending the city.

Looking at the Wu army rushing over from the city, although Gongsun Jian was sure, he couldn't help but be a little nervous. A large-scale bloody battle is about to begin, and it may have far-reaching consequences, involving his future plans and future development. This battle must be won by him, and he must win it cleanly, effectively killing and wounding more enemy troops.

The battle was fierce, very tragic from the beginning.

Of course, this tragedy belongs to the other side, Wu Jun.

Gongsun Jian's strategy was to completely hurt Wu State in one battle, at least for a long time, Wu State no longer had the courage to meddle in the affairs of Zhou State, especially not daring to threaten the territory of Gongsun Jian in the Northwest Three Provinces.

Fortunately, Sun Sheng was very cooperative, and as soon as he came up, he used all his strength, and the 30,000 army charged collectively, trying to take Dingxi County, which was not strong in defense, in one go. But he really underestimated Gongsun Jian.

The mine array 800 to 500 meters away from the city wall came up and gave Wu Jun a blow to the head. Fortunately, the production of gunpowder on Gongsun Jian's side has always been a problem, so there are not many mines. There is also the fear that it will seriously hit the morale of the Wu army at the beginning, so that it will not be possible to inflict heavy losses on the other party in one fell swoop.

After losing nearly 1,000 people, the Wu army finally broke through the mine array smoothly and approached a range of nearly 300 meters. And at this moment, those catapults on the head of Dingxi County began to exert their power. After a burst of bombardment, Wu Jun was really dumbfounded. Fortunately, the speed of the charge was fast enough, and coupled with the large number of people, most of the Wu army passed this dangerous distance. But more than 2,000 corpses were left behind.

When there were less than a hundred meters away from the city wall, the defenders began to attack with strong crossbows and bows and arrows, but the effect was not outstanding, and when the Wu army attacked within thirty meters of the city wall, the arrow rain suddenly became dense, and there was no time to stop.

Repeater, a Gongsun Jian participated in copying in his previous life because of his hobbies. Legend has it that this was a sharp weapon invented by Zhuge Liang during the Three Kingdoms, but it was later lost. Even the products copied under the superior technological conditions of the previous life have not been able to achieve the effect recorded in the history books, but this does not hinder its practicability. It's just that the range is too close.

The effective range of the repeater crossbow does not exceed 20 meters, and even more than 15 meters, it cannot play an effective killing role against soldiers with armor protection. However, Gongsun Jian and they shot from top to bottom according to the city, and the effective distance was more than 20 meters, and the first batch of Wu troops to attack the city were all light soldiers, and they did not wear too thick armor in order to facilitate carrying siege equipment.

Today's steel mill in Linshui County, in fact, this name has long been inapplicable. The entire plant has long been divided into several large blocks. The first part is the smelting of iron ore, and the second part is the rough processing of steel, which begins to be subdivided after reaching this point, and some of the steel ingots produced will be sold, and they are very sought-after. The reason is simple: large quantity and high quality.

Next, some of the rough-machined ingots will be refined, and then processed into various types of weapons and equipment according to different needs. Just like the crossbow arrows made of stainless steel used today, each arrow is different from ordinary arrows, and the whole body is made of pure steel, which is heavier and more penetrating. The only drawback is the short range. A pure steel arrow about six inches long can shoot at a maximum distance of seventeen or eighteen meters, which is the distance of a flat shot, and if you shoot down, it can reach about twenty-five meters because of its own weight, but the lethality is amazing, as long as it is shot, it can basically penetrate. Coupled with the three-edged blood groove of the crossbow arrow itself, it can be said that as long as the torso is shot, it is basically a dead word.

It is precisely because of such a sharp weapon that Gongsun Jian has such courage and confidence. The crossbow arrows that had been accumulated for a long time and amounted to 200,000 were all sent to Dingxi County this time. In addition, in order to solve the shooting gap caused by the addition of arrows, Gongsun Jian used the three-stage attack of the early musketeers in the previous life. All the crossbowmen were divided into three shifts, and after the first row of ten crossbows was fired continuously, the second row immediately made up for it and continued to shoot, while those who finished shooting stepped back and stepped up to replenish and install arrows.

Now Wu Jun has suffered a big loss. In just one cup of tea, more than 80,000 crossbow arrows were shot from the head of Dingxi County, and even if it was a one-tenth hit rate, the damage of the Wu army was as high as 8,000 people. The Wu army attacked by Wu Yang was like wheat that had been cut, and they fell one by one in an instant.

However, some people still rushed to the bottom of the city walls, but before they could erect the ladders for the siege, all kinds of rolling logs and stones fell on the top of the city like hailstones, mixed with the explosion of 'grenades'. All of a sudden, the corpses under the city were covered all over the ground.

Sun Sheng, who was not far away, was riding on a horse and quietly watching the battle, but what he didn't expect was that Gongsun Jian's soldiers guarding the city would be so powerful. 30,000 men charged, and although some of them reached the city wall, the total number was estimated to be less than half of the time they set out. This is also his Sun Sheng's way of governing the army, otherwise he would have lost his morale and military morale without fighting.

"Rush. The reserves were all pressed to support the front army. Sun Sheng waved the order flag in his hand. The reserve of 20,000 sergeants rushed forward again without hesitation.

At this moment, Sun Sheng knew very well that if the reserve force was not up, the soldiers who died in front of him would be in vain, and at this moment, almost all the fierce battles were concentrated within less than two hundred meters in front of the city wall, at least those obstacles in the distance would no longer be threatened. In addition, Sun Sheng asked the archers to shoot arrows collectively at the head of the city when they arrived at the right position, so as to suppress the resistance of the head of the city.

I have to say that Sun Sheng's crowd tactics still had a certain effect. The increasing number of siege troops under the city has caused problems in the scheduling of Gongsun Jian's side, and it is easy to let go of those who shoot far away, and those who shoot near and far away are quickly replenished.

However, Gongsun Jian was still very calm, and after observing the situation on the battlefield, he ordered someone to send a signal. Three puffs of wolf smoke were ignited in an instant, and then in a field not far from the battlefield outside the city, thousands of soldiers suddenly appeared, rushing towards the rear of the Wu army, the purpose was obviously to prepare to attack Sun Sheng.

There is a saying that 'shoot a man first shoots a horse, and a thief captures the king first'. This set has been used since ancient times. All the 50,000 soldiers under his command were sent out to attack the city, while the remaining 30,000 people were guarding the camp to prevent a sneak attack, and at this moment Sun Sheng only had 3,000 pro-army guards left by his side.

Fortunately, the number of people who attacked them was not large, about five thousand or so. According to the combat power of Sun Sheng's own soldiers, these people are basically not their opponents. But don't forget, Gongsun Jian's troops are not ordinary soldiers. What's more, their equipment and weapons are superior to those of this era.

"Hehe, Gongsun Jian'er is nothing more than that. Do you really think I'm going to leave all 30,000 soldiers in the camp? Sun Sheng rode on his horse and looked at the soldiers rushing towards him, without the slightest fear. Instead, there was a slight disdain on his face.

"I'll just tell you where Ding Feng's people went. You're waiting for me here, huh? Hahaha, Gongsun Jian is afraid that you are going to miscalculate this time. With that, Sun Sheng ordered people to wave the command flag, and the rear camp suddenly opened the camp gate, and a team of 10,000 people rushed out and went straight to the army that attacked Sun Sheng.
