Echeng, geographically, is the "Wuchang" of the later generations, and at this time and Xiakou, that is, the "Hankou" of the later generations, still uses its original name.

The city wall of Echeng is far inferior to later generations, Xiakou is still only a small port, the three towns of Wuhan are experienced in the Eastern Wu Dingdu, the Eastern Jin Dynasty moved into Runan population, the Southern Song Dynasty built Xiakou, the Tang Dynasty set up a festival in the middle of the envoy, and the Southern Song Dynasty Yue Fei guarded the town...... After a series of strengthenings, it became the center of the three towns.

Now Echeng has not even carried out a wave of strengthening of the capital of Eastern Wuding, although it is the Jiangxia office, but it is only stronger than the ordinary county seat, but in the state city, it is ...... Medium to low.

The most important barrier of Jiangxia to the east is still the previous Chukou......

In addition to the city tower, the city wall is not five or six steps wide, and the sharp weapon of the Gongkou city can be transported directly to the mouth by water, and not more than ten miles by land, you can go to the root of the city wall!

"Daddy! At this time, how can I go back to South County? I'm ......" Huang Jie retorted excitedly after hearing Huang Zu's arrangement.

"Shut up! Regret should not let go of that Youheng, look at you now...... Also learned to talk back? Huang Zu said angrily.

"Someone, his talisman! Escort to Xiling! Huang Zu ordered directly.

Within a day of Huang Zu's forcible departure of Huang Jie, he received the news that Sun Ce had led his army.

Sun Ce and Zhou Yu were not ready to go through the city gate, and directly transported sixty white cannons to the southwest of Echeng.

The geographical location of Echeng is excellent, with the river and the river, the lake and the mountain, the left controls the Luqi, the right is connected with Fan Han, not only the east is close to the remaining veins of the Mufu Mountain, but also close to the water ...... That is, the lower reaches of the Han River, which is easy to dig a moat.

However, the current Echeng is not the "Jiangdong Town", and it is easy to bypass the mountain roads and intermittent semi-natural moats and come to the city......

Facing the city wall that was only five zhang high and five or six steps wide, Zhou Yu chose a direction, did not take the city gate, chose a location that was easy to quarry for bombs, and avoided the city tower, and directly set up the camp, and opened the posture of the white cannon in front of the camp, looking like he was going to break the wall and attack.

Huang Zu didn't expect that Sun Ce and Zhou Yu didn't even want to leave the city gate, above the city gate was the city tower, and the city wall in the city tower section could be wider and easier to defend.

However, when attacking a city, it is generally carried out around "climbing the wall" and "breaking the door", and it is generally a two-pronged approach, and if one side can succeed, the attacking side can see hope.

Especially "breaking the door", after all, even if the wall is successful, it will only make the proportion of offensive and defensive casualties closer, and ten successful climbs may not be able to finally stand firm once.

And if the door is broken, as long as it is not blocked, it is a long-term passage!

However, as soon as Sun Ce and Zhou Yu came, they didn't look at the city gate, and they didn't have the intention of building wells and ladders on the spot, but opened mountains and took stones......

This is also the siege method advocated by Bai Tu - avoid climbing the tower, so as not to cause too much damage to the enemy and us, we have to directly tear down the wall!

As a cold weapon counterweight catapult, the white cannon is much stronger than the primary artillery in the Song and Yuan wars in history, and in the Song and Yuan dynasties, both sides also had artillery put into use, but the effect was not good, and in the end it was the "return cannon" as a cold weapon played a decisive role.

However, it is obviously not wise to ignore the development of firearms for this reason, and the "future" has proven that although the return artillery is superior to the primary artillery in all aspects, it is ...... The return cannon is basically the limit of the cold weapon catapult, and the development of artillery has just begun.

Since the Anglo-French War, after France tested its artillery, artillery has been increasingly developed under the impetus of industrial civilization.

In the battle between the Ming Dynasty and the Later Jin, there must be artillery on the scene in large-scale battles, whether it is the "imported" Franc machine gun, or the self-produced mighty general cannon, which has never been absent in the late Ming and Jin wars......

It's a pity that the Qing Dynasty after Chengping, although it also relied on red-coated cannons to quell the chaos and fight against Tsarist Russia, but ...... Compared with the West, it gradually adapted to the "weak chickens pecking each other" in firearms, developed slackness, and even took the initiative to suppress it, and finally opened the modern history of the Chinese nation in a humiliating way.

And now, because Bai Tu strongly advocates the siege mode of "breaking the wall", whether it is the generals who lead the troops in terms of tactics or the technology of Gongkou City, they are trying their best to develop in the direction that Bai Tu admires......

Blast furnace ironmaking has already been modeled, reverberatory furnace copper smelting is still being tested, and the steel filling method was applied in a small range last month!

Although it is refracted to the application of war, it still needs to be accumulated, and the initial artillery is not as good as the return artillery, in the case of the already "white public artillery", it will take longer for the artillery to have real combat significance, but ...... Bai Tu has been able to look forward to the emergence of the Mercy Breaker.

As for the current Echeng......

Even if the city walls of the Chengji World are much taller and stronger because of the existence of battle armor, and there is a people's defense bonus, it seems that at the scale of today's Echeng, it can be slowly "knocked open" with the use of white cannons!

On the evening of the day when he set up camp, Sun Ce, who had collected enough stone bullets, first shot at the city wall in front of him for a while.

Huge stone bullets smashed on the city wall, although there was a pale golden barrier of popular support, which removed a lot of strength, but it still made the defenders above feel a little "vibration" under their feet.

And I don't know if it's an illusion, it's just the first round, which lasted for a quarter of an hour of wild bombardment, and it seems to be ...... At the end, the tremors of the walls were a little more pronounced than at first!

Sun Ce had no intention of attacking, so he pushed the white cannon back after smashing, arranged a vigil, and rested the whole army......

Early the next morning, the stone collection continued, which was also the weakness of the catapult compared to the artillery, the stone projectile needed to have weight to be powerful, and the transportation was inconvenient, so it was very dependent on the in-situ collection of stone projectile materials.

In contrast, the original solid bullets and scattered shells of the artillery were better, although they cost more, but they ...... At least it is much easier to transport a fist-sized solid iron bullet than a stone bullet.

At noon and in the evening, after being bombarded again, Huang Zu finally couldn't help it, and in the middle of the night, he sent troops to attack from the south gate and the west gate at the same time, wanting to attack Sun Cejun in the southwest at night!

However, Zhou Yu had long expected that in this case, the Echeng guards would definitely seek a night attack to retreat from the enemy, and with Huang Zu's temperament, he couldn't endure it for a few days, so he had already arranged a batch of scouts......

Seeing that the sneak attack had turned into a Ming war, Huang Zu still wanted to rely on the physical strength of the soldiers to force the attack - he also knew in his heart that tonight was the last chance, and Sun Ce would not let down his vigilance after that!

At least for now, the defenders of Echeng had rested during the day, while Sun Ce and Zhou Yu's armies had mostly just been interrupted from resting and hastily entered a state of engagement.

And...... At least in the case of a night attack, it is mainly a frontal charge, and it is impossible for both sides to set up a military formation in the dark, and even if they make some preparations in advance, they will not be able to notify the whole army, and it will be easier to bomb the camp.

However, Huang Zu obviously underestimated the huge gap between the two sides from generals to soldiers, the same night battle, the same can not get real-time command, can only be fought by the grassroots officers below Dubo, and the other side is obviously not well rested...... But it was still Sun Cejun who won a big victory!

Huang Zu's sneak attack was not enough for Sun Cejun to bomb the camp, especially some of the soldiers affected by the "heroic posture", who would defend against night attacks and play the effect of charging into battle.

Huang Zu's vanguard Chen Zuo and Deng Long were both killed by Sun Ce, and then chased Huang Zu all the way back to the west gate of Echeng, only to be forced back by the defenders on the city tower with bows and arrows!

Although Huang Zu saved his life, Echeng not only lost his troops, but also further reduced his morale......

Since the two defeats at Chukou, the morale of Jiangxia soldiers has been at a low point, and "fortunately" Huang Zu has always been very experienced in dealing with defeats, so he was barely appeased.

However, after this night attack, Huang Zu was no longer able to organize another attack - the overall morale had been decided, and now the defenders of Echeng were afraid that they would collapse when they left the city.

It seems that the only thing that can be done is to be lazy every day, and when Sun Ce pushes the white cannon into range, he shoots some weak and chaotic arrows, but ...... Sixty white guns, and four days later there are still fifty-one!

Most of them are self-inflicted...... After using too much, the details of the parts were damaged, although they could still be used after dismantling and putting them together, but they still reduced the number of three frames - the arm shaft was too easy to damage, and you should bring some extra spare in the future...... Zhou Yu wrote it down.

If you can't rush to the front, you can't effectively destroy these big guys with arrows alone.

Although Huang Yueying did not appear again, she sent the design of a catapult to Huang Zu through the Huang family's general.

It's just that...... With the current situation in Echeng, it is too late to build, and it is very difficult to get out of the city to collect materials.

Perhaps it was precisely because she understood that she could no longer stop her uncle's defeat, so Huang Yueying didn't want to see her uncle......

As Huang Chengyan said, since Huang Zu has chosen his own path, he must pay for it himself!

On the fourth day, the city wall of Echeng collapsed......

Sun Ce took the lead and rushed forward with a "heroic posture".

Although it was only three people wide at the bottom, it was too late to plug the cracks in the collapsed city wall, or even ...... Because after the collapse of the city wall, the morale almost collapsed, and the defenders on the city wall shot arrows a little sparsely.

On the contrary, on Sun Ce's side, many generals under his command, especially those who are now leading the charge, are mostly Wu Jun's disciples, and many of them have served Sun Jian.

On the one hand, it is to avenge the old master, and on the other hand, there is also the encouragement of Sun Ce's "heroic appearance", which is more and more imposing!

Sun Ce and a horse (A) took the lead in the gap to kill the past, although there were defenders overflowing the defense, but it was difficult to have Sun Ce's enemy, within five steps, the defenders were almost incapable of getting close, and pressed the battle line back to the gap in the city wall.

A green-armored young general behind him also rose up at this time, and took advantage of Sun Ce's almost single-handedness to suppress the defenders of the gap, and was the first to enter the city with a leap and a drill!

It can be seen that this young general's facial features are very young, and he is a little more immature than Ding Feng when Qu'a first went to the battlefield, but he is already a gilded battle armor.

Seeing that someone had killed and entered, the defenders who had gathered in the crack in the city were suddenly in a mess, and no one cared about the heavy objects that were being pushed over and wanted to block them.

"Hahaha, Gongji, well done!" Sun Ce laughed and boasted about this young general, and at the same time, the battle spirit surged, and the figure of twenty-eight horsemen rushed out of the surrounding "brush, brush, brush", completely breaking the defense at the gap in the city wall.

In the city, more and more Jiangdong troops poured in, and after Huang Zu saw this scene, he ignored the advice of the deputy general next to him, and silently turned around and went home......
