As soon as the Jing army approached the bottom of the urn city, the Wei army on the city wall lifted the felt cloth, revealing a black cannon muzzle, which was thicker than a bucket, and then a deafening roar sounded on the urn city, the cannon muzzle spewed out flames several feet long, and the black iron ball was thrown out. Top Novel,

Cannon!

Everyone was taken aback, Cao Cao also had artillery, and it was the kind of super-large caliber artillery, which was larger than the caliber of the red-clothed cannon owned by the Jing army, and the iron ball thrown out was a solid bullet, although it was not as powerful as the flowering bullet, but a solid bullet was enough to penetrate a column of the Jing army.

The Jing army was taken by surprise and suffered heavy casualties, and was forced to suspend the offensive and withdraw to the battalion.

When Liu Ze received the report, he couldn't help but be secretly surprised, Cao Cao actually made artillery, which was too unexpected. It seems that he still underestimated the cottage of the ancients, Cao Cao suffered the loss of artillery in Xiapi, and naturally wanted to develop this powerful weapon with all his heart. Cao Cao's subordinates are full of talents, and there are countless skilled craftsmen, if there is a sample, it is naturally not difficult for the cottage to clone a cannon.

The key is that Liu Ze does not know how his artillery-making technology was leaked, and the manufacture and preservation of artillery has always been classified as top secret in the Jing Army, and all craftsmen and technical materials have strict confidentiality measures, and it is by no means easy for Cao Wei to steal them.

Liu Ze thought of a report provided by Jin Yingwei a few years ago, Cao Jun had transported a large number of items in Xiapi, although the vehicle was very tightly covered, but from the ruts, it could be seen that the goods transported must be very heavy. Combined with Cao Cao's later dispatch of Zheng Hun, a master craftsman, and hundreds of craftsmen to Ziyun Mountain near Xudu, Jin Yingwei analyzed and reported that Cao Cao must be developing some secret weapon. It's just that Cao Jun is very strict against Ziyun Mountain. The Golden Eagle Guard was unable to infiltrate and probe for details.

Now it seems that Cao Cao really built a cannon in Ziyun Mountain, and this Zheng Hun is really a genius. It's just that what Liu Ze is puzzling is what Cao Jun transported out of Xuzhou at the beginning, and when Xuzhou was evacuated that year, all the city fire cannons were transported to Wuchang. Nothing will be left behind.

However, it is useless to explore the reason now, as far as the situation is now mastered, Cao Cao deployed nearly seventy or eighty cannons in the two urn cities in the east and west of Xudu - no, it should be called a fort, and the caliber and range of these cannons are far more than the bronze cannons, and even larger than the red-clothed cannons, the only difference is. Cao Jun did not master the technology of flowering shells, and these cannons could only fire solid and shotgun. It seems that when Zheng Hun was developing artillery, he still encountered a bottleneck in the technology of flowering shells. But even so, the power of these cannons is quite amazing.

Cao's forts were built very strongly, and the strength of the infantry alone was simply not enough to conquer them, and defeating these two forts was necessary to conquer Xudu. The decisive battle with Cao Cao had been carried out to the last moment, and Liu Ze had absolutely no intention of giving up halfway.

The battle is on this. Stratagem and trickery no longer play a role, and what the two sides fight for is the real strength.

Bronze cannon PK cast iron cannon, which will be the first firearms clash in the history of mankind. Liu Ze's bronze cannon is small in size and light in weight, but with the killing weapon of the flowering shell, it still has a lethal effect on the Cao Jun artillery on the fort. But the only fly in the ointment was that the range of the bronze cannon was not as far as that of the cast iron cannon. If the bronze cannon wants to hit the turret, it must enter the range of the cast iron cannon, and the solid bullet of the cast iron cannon is also amazingly powerful, once hit, the bronze cannon will directly turn into a pile of scrap copper.

Artillery battles on both sides. From the very beginning, it was very tragic, both sides concentrated their firepower, trying to take the first shot, up and down the battery, artillery fire was continuous, the smoke of gunpowder was filled, and the sound of explosions was deafening.

The bronze cannon had a high hit rate, and almost every shot hit the target, but the cast iron cannon was thick and heavy, and it was not easy to blow it up, but the Wei gunners on the turret suffered heavy casualties. The hit rate of the cast-iron cannon is not high, but the damage rate is almost 100 percent, and once hit, it is not spared.

The artillery battle continued, the two sides were completely fighting for attrition, at the beginning both sides were full of firepower, the battle was unprecedentedly fierce, after a few days of fighting, the artillery on both sides had varying degrees of attrition, and the firepower was naturally not as fierce as it was at the beginning. The self-damage of the cast iron cannon of the Cao army is also very serious, the congenital defects in the process, so that the cast iron cannon is frequently blown up, and the self-damage of the bore alone accounts for about one-third of the loss of the Cao army's artillery, and the artillery battle continues, and the situation is more and more unfavorable for the Wei army.

The loss of the bronze artillery on the side of the Jing army is also very great, after all, the solid bullet of the Wei army is both heavy and fierce, as long as it is hit, everything is broken, but the artillery of the Jing army did not retreat half a step, after the most advanced artillery was destroyed, the reserve artillery immediately went up, a belief in supporting all the artillery officers and soldiers, even if it was fought to the last man and a cannon, it would never retreat.

While the artillery battle was going on, the infantry and cavalry of the Jing army were not idle, and carried out a large-scale horizontal attack on the positions outside Xudu.

The Wei army gathered more than 800,000 troops around Xudu, and it was naturally impossible for such a huge number of troops to shrink into the city of Xudu.

The great duel between the two sides at the level of millions of troops, its tragedy is no longer enough to be described as earth-shattering, both sides have put on a decisive battle posture, many strongholds are several degrees easy to defend, under the city of Xudu, the corpses are pillows against each other, blood flows like a river, these blood flows down, and soon freezes again, and there are black and purple ice ballast everywhere.

The battle is in a stalemate, the fighting continues, and no one knows when or how the battle will end. Slaughter! Endless, endless killing......

┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄

Compared with the bloody battle in Xu Du, the Shangdang side is much calmer.

After Zhang Renbing took Taiyuan, the army waved south, and formed a joint encirclement of the Wei army of Shangdang, but the terrain of Shangdang was dangerous, easy to defend and difficult to attack, and it was a place where soldiers must fight since ancient times.

Xu Huang defended by danger, let Zhang Ren challenge in every way, life or death is not to fight, Jing Jun scolded outside the village every day, foul language was endless, Xu Huang turned a deaf ear, ignored it.

Although Xu Huang was calm, he annoyed someone.

It's not someone else, it's Xiahou Shang, the deputy governor of Hedong.

After Xiahoudun was injured and returned to Yecheng, Xu Huang acted as the governor of Hedong, and then Cao Cao officially appointed Xu Huang as the governor of Hedong, with full responsibility for the defense of Shangdang, and at the same time sent Xiahou Shang to Shangdang as Xu Huang's deputy.

Xiahou Shang is Xiahou Yuan's nephew, young and vigorous, quite courageous, among the younger generation of the Cao family, can be regarded as an outstanding figure, Xiahou Shang and Cao Pi have a very close relationship, this time Cao Cao was appointed as the deputy governor of Hedong, but also because of Cao Pi's recommendation.

Li Tong's men and horses were also transferred to Shangdang, and the Wei army gathered nearly 150,000 troops in Shangdang, and Xu Huang adopted a strategy of holding on without fighting for the strong offensive posture of the Jing army, which made the young and vigorous Xiahou Shang very dissatisfied. In his opinion, the Wei army is not at a disadvantage in terms of troops, and it should take the initiative to attack, and there is no big problem in recapturing Jinyang.

"This old guy is really useless, the King of Wei actually sent him to be the governor of Hedong, it's really a wretch!" Xiahou Shang slandered Xu Huang and despised him extremely. He asked Xu Huang to fight three times, asking to lead a group of men and horses to go out of the village to fight a decisive battle with the Jing army, but Xu Huang never agreed, and said in a hurry, Xu Huang suppressed him with the title of governor. Xiahou was still extremely angry, and gradually held a grudge against Xu Huang.

Xu Huang refused to fight, but he also led troops to inspect the villages from time to time, and on this day, he met Zhang Ren unexpectedly in Mengtou Cottage. (To be continued......)
