As the saying goes: a wise man thinks a thousand times, and there must be a mistake; A fool thinks a thousand times, and he will get one. Obviously, Du Chen is the wise man in the proverb, he never expected that the trial match would use his reputation to get so many soldiers, but Du Chen knew what to do, he really didn't have a good impression of the Shi clan, even if Du Chen chose again, he would kill those Shi clans.

At the specified time, the Yuan army obviously did not show any signs of surrender, the Yuan army on the city wall was actively preparing for battle, and the Cao army under the city was obviously not idle, taking advantage of this time, the Cao army was also preparing for the siege of the city.

Yecheng is definitely an easy to defend and difficult to attack city, the towering city walls and wide moat are daunting, but Du Chen is not in a hurry to attack the city, now the whole Hebei has no strength to fight hard with Cao Jun, as long as his army surrounds Yuan Shang, can he still be afraid that he will not be able to escape,

Moreover, today's Yuan army is obviously highly morale, Du Chen's order to attack Yecheng is definitely a thankless thing, Cao Jun has embarrassing catapults, with these catapults, it is enough to make the Yuan army on the city wall suffer,

Du Chen didn't use these catapults when he attacked Liyang, firstly because Du Chen wanted to hide his strength, and secondly, because it was too easy to conquer Liyang City, and no one gave him such a chance.

Now it is finally the time for these counterweight catapults to exert their might, after the improvement of skilled craftsmen, the power of Cao Jun's counterweight catapults has obviously increased a few points, this is Du Chen's dependence, even if Yuan Jun is cowering in the turtle shell, Du Chen can also make them uncomfortable.

On this day, Du Chen gave an ultimatum to the Yuan army in Yecheng, if the Yuan army could not hold out and refused to surrender, the Cao army would launch a strong attack on the Yuan army in Yecheng. However, for Du Chen's words, the trial obviously did not take it to heart, and the Yuan army in the city had already prepared, so he was ready for the Cao army to attack the city.

Without a satisfactory answer, Cao's army left the camp. Set up a formation, looking like they were going to storm Yecheng, but the soldiers of the Yuan army on the wall of Yecheng waited for a long time, and they did not hear the horn of Cao's attack and charge.

In this regard, the soldiers of the Yuan army felt quite puzzled, the Cao army under the city had already set up a position, but why had they not attacked until now,

Just when everyone was puzzled. Cao Jun's counterweight catapult was finally erected, one after another counterweight catapult set up a formation, looking murderous, countless Cao Jun soldiers are transporting stones to the catapult, and now all the catapults are ready, just wait for Du Chen's order, dozens of boulders will soar into the sky, straight to Yecheng.

Du Chen took a look at the catapult phalanx, which had been fully prepared. Then with a wave of his hand, he ordered all the catapults to start throwing stones.

With Du Chen's order. The catapults of the catapult phalanx launched an attack on Yecheng, and one after another boulders were thrown into the sky by the catapults, and they roared, flying towards the walls of Yecheng with a power that ordinary people could hardly match.

There was a loud bang~~, and a boulder smashed into the city wall. This huge impact makes people feel quite shocked, although this boulder smashed on the wall of Yecheng, but the soldiers of the Yuan army felt that this boulder smashed on their chests, and the depressed people didn't know what to say,

Perhaps. The soldiers of the Yuan army did not have a chance to speak at all, one after another boulders roared and smashed into the walls of Yecheng, of course, not all the boulders smashed on the city walls, many boulders roared and smashed into the soldiers of the Yuan army on the city walls,

The boulder is obviously not something that can be resisted and confronted by manpower, a boulder smashed on a person, and immediately turned this Yuan army soldier into a meat pie, and suddenly blood splashed everywhere, and everyone who watched it was stunned, not knowing how to be good, obviously, Yuan Jun soldiers did not expect that they were facing such a situation,

At this moment, the tall city wall can not bring people the slightest sense of security, one after another boulders smashed all the hopes of the Yuan army, the boulders roared, and constantly flew towards the wall of Yecheng.

A round of boulder attacks, most of the Yuan army soldiers have fallen into fear, even if they can hide behind the city wall, Cao Jun's trebuchet is so sharp, how can the city wall withstand such a fierce attack by Cao Jun,

A round of boulders thrown, Du Chen showed a slight smile, this round is just to test the waters, and the next is the most feared time for Yuan Jun, when he was in Xuchang, Du Chen was not idle.

He already knew that Yecheng was definitely a difficult bone to gnaw, in order to conquer Yecheng, Du Chen made sufficient preparations, in addition to improving the range of the trebuchet, Du Chen also invented an incendiary bomb,

The oil is placed in a container, and then the cotton cloth is used as a lead, the lead is ignited, and then thrown with a trebuchet, and when the container is broken, the oil will be ignited by the fuse, so that it can produce a huge destructive force in a very short time.

"Change the incendiary bombs." Du Chen said to the soldiers beside him in a deep voice, although the incendiary bombs are still in the experimental stage, but the actual effect is surprisingly good, so when he set out on the expedition, Du Chen specially ordered people to prepare a lot of incendiary bombs.

Hearing Du Chen's order, the soldiers moved down the loaded boulders one after another and replaced them with incendiary bombs ordered by Du Chen.

"Reloaded." After loading the incendiary bombs, all the soldiers in charge of loading reported that each catapult had a different division of labor, some were specifically responsible for loading, some were responsible for transporting ammunition, and some were specifically responsible for firing.

"Ignition." The general of the Cao army roared loudly, the movements of the soldiers were uniform, and everyone lit the fuse one after another, and then as the general roared, dozens of incendiary bombs with fire roared towards Yecheng,

I thought it was a boulder that rushed to the sky, but this time the situation was obviously different, one by one the things that were burning were thrown by the enemy, which surprised the soldiers of the Yuan army, and they didn't know what the hell Cao Jun was doing.

But then they knew, one by one, the canisters of fire rushed over with flashing fire, and as the incendiary bombs burst, the oil splashed out, and then ignited by the open flame above the fuse, which instantly stirred up a large area of fire.

The soldiers of Yuan Jun obviously didn't expect Cao Jun to have such a killing weapon, and the incendiary bombs attracted countless fires, although some of the fire oil was not ignited, but the incendiary bombs smashed on the soldiers obviously cost human lives.

After only two rounds of incendiary bombs, the entire Yecheng city wall was caught in flames.

Seeing this situation, the judge obviously didn't know what to say, and the city defense equipment he had carefully prepared seemed to have no effect at all, and Cao Jun's trebuchet destroyed a qiē, and also destroyed the hope of victory for the soldiers of Yuan Jun.

Boulders after boulders, incendiary bombs one after another, the Yuan army did not have any defensive measures at all, fortunately, the Cao army did not attack at this time, otherwise, the Cao army must have taken the city wall of Yecheng,

For the actual combat table of incendiary bombs, Du Chen was obviously extremely satisfied, and let the trebuchet phalanx throw a few rounds, and then Du Chen ordered the defenders, no matter when, the siege machine is the key to determining the victory of a battle.

Seeing Yuan Jun trembling behind the towering city wall, Du Chen had a heartfelt sense of pride, where is Yuan Jun the opponent of Cao Jun, no matter how difficult Yecheng is, in front of the powerful Cao Army, there is still only the share of being conquered,

Today's battle let everyone in the trial and Yecheng know that the combat effectiveness of Cao Jun and Yuan Jun is obviously very different, Yuan Shang is very envious of Cao Jun's siege weapons, but envy is envy, he obviously has no way to target Cao Jun's trebuchet.

The only way is to lead the troops out of the city and storm the trebuchet phalanx of the Cao army, if the situation is in order, the Yuan army may be able to solve the threat of the trebuchet, but it is not easy to attack the Cao army's position,

Du Chen obviously knew the power of the trebuchet, in order to protect the trebuchet, Du Chen definitely arranged the most elite troops of the Cao army, focusing on protecting the trebuchet phalanx,

When Yuan Shao was in the limelight, there was no way to start a positional battle with the Cao army one-on-one and break into the Cao army's camp, and now with these temporary troops, he wants to break through the Cao army's heavy defenses, and then burn the catapult, which is obviously a fool's dream.

"If this disaster is not eliminated, how can our army defend Yecheng!" Looking at the trebuchet being dismantled under the city, and then looking at the wolf appearance of the soldiers on the wall of Yecheng, Yuan Shang looked angrily at all the generals of the Yuan army and asked,

There are not many defenders in Yecheng, even though under the supplement of the scholars, the guards in Yecheng are a lot more sufficient, but their number is at best similar to the Cao army that has become, only forty or fifty thousand people,

There are indeed a lot of people who help defend the city, but it is obviously impossible to expect them to burst out with great combat effectiveness, the people are the people, and when they really go to the battlefield, they can only be slaughtered.

Everyone heard Yuan Shang's roar, and they fell silent, everyone knew that today's attack was just Cao Jun's actual yàn, Cao Jun didn't make the slightest movement at all, just let the trebuchet throw a few rounds, but just like that, Yuan Jun had already suffered heavy casualties,

Although the Cao army has withdrawn now, it is conceivable that the Cao army's attack tomorrow will definitely be more ferocious, today the Cao army has not sent a single soldier, if the Cao army sends a large army tomorrow, how should the Yuan army on the city wall deal with the menacing Cao army,

Looking at the silent crowd, Yuan Shang's heart couldn't help but sink, at this time he regretted a little, regret was absolutely desperate, against Cao Jun, if he chose to abandon the city and surrender that day, I am afraid that he would not be as desperate as today,

Cao Jun's catapult shattered the hopes of victory for many people, and of course even Yuan Shang was no exception.

Yuan Shang's changes were obviously seen by the judge, he stared at the outside of the city wall of Yecheng, Cao Jun's trebuchet phalanx, and couldn't help but show a little hideous, at this time he had an impulse in his heart, that is, to destroy those trebuchets regardless of a qiē.
