Just as Zhou Yu, who had also studied Cao Wei for 20 years, predicted, this time to capture Jingzhou, Sima Yi and Cao Zhang, after consulting with Cao Zhi, had already transported the thunderbolt cart that had previously shown great power in the Battle of Guandu to a county at the southern end of Weixing County, which was closest to Shangyong, in case of emergency.

The use of the thunderbolt in this battle was the result of Sima Yi's careful consideration, and the thunderbolt used in the Battle of Guandu was a siege weapon that used a thicker, extremely elastic bamboo as a lever to throw huge stones out. And this time the catapult that came with the army, its principle is similar to the thunderbolt car, but the size is only less than half the size of the thunderbolt car, although it is easy to transport, but the power is also greatly reduced, and it is tantamount to a fantasy for the Wei army to rely on the catapult in the army to smash the gate and city wall of Shangyong.

Therefore, Sima Yi and Cao Zhangcai decided to sacrifice in advance the thunderbolt car that they wanted to use in the capture of Xiangyang City, at this time, the thunderbolt car has been improved a lot compared to the battle of Guandu Cao Cao, not only the expanded car body, but also the use of more stout bamboo poles obtained from Shu, and the skilled craftsmen of Wei State installed the cardinal in the car, so that its power is more than double that of the thunderbolt used in the previous battle of Guandu, but the action is also much more cumbersome, so Cao Zhang dispatched 10,000 horses, while transporting and escorting, It was just to transport ten thunderbolts outside Shangyong City.

Less than ten hours after setting off from the camp, the non-stop Cao Zhang was already on the way back to the camp, although the thunderbolt was bulky, but fortunately, the county where the thunderbolt was stored and Shangyong were not separated from any mountains and rivers, some were just a flat river, which made Cao Zhang not spend any energy, but needed manpower to maintain the balance of the thunderbolt, and then there was a large number of boulders specially equipped for the thunderbolt, all of which were worn by the craftsmen, and would not slow down or lose strength under the rotation in the air. Striking at the gates or walls of the city will undoubtedly cause great damage to the gates and walls.

Along with the Thunderbolt and the Boulders, there were more than a dozen craftsmen who had transformed the Thunderbolt Car, and only they were the Wei Army, who had almost never used a Thunderbolt before, who knew how far away they could accurately hit the target, and if they were not there, it would be difficult to control it far or near, and a lot of boulders and time would be wasted.

But what Cao Zhang didn't know was that it was the craftsmen he brought to guide the use of the thunderbolt that indirectly made him and Sima Yi's dispatch a very painful memory......

"There are only more than thirty miles left from our military camp, you cheer up, after returning to the camp, the heavy task of attacking the city has nothing to do with you, and when you have laid down the mediocrity, the beautiful women in the city, and you will be selected first!"

For his 10,000 headquarters people, Cao Zhang naturally made a wish without hesitation, he knew that as the brother of Cao Zhi, the lord of Wei, as long as he maintained a basic consistency with Sima Yi in terms of strategy and tactics, Sima Yi was already very grateful to him, as for some other matters that were trivial in his eyes, how he wanted to do it, Sima Yi would let him do it, this was a small tacit understanding reached between him and Sima Yi, but no one said it clearly.

The 10,000 sergeants under his command heard the wish of their leader, all of them showed a satisfied smile, as Cao Zhang's headquarters, they were still treated very favorably in this expedition, and the battle to overcome difficulties was almost never let them go, which couldn't help but make them have a lot of superiority, and felt that the war in the Central Plains was much easier than facing the alien races in the north, after all, when the Wuhuan cavalry faced them, until the last few people had to fight with their lives.

Imagining those beautiful women in Jingxiang, Wei Jun's legs and feet moved even faster, they just regarded this time transporting the thunderbolt car as a task that was not difficult, so they were getting closer to their camp, and their hearts became more and more relaxed, and they were all on the road, and they didn't care about the surrounding terrain at all.

After walking less than five miles, the Wei army arrived at a slightly muddy place, if they were lightly armed, these muddy would not cause them any difficulties at all, but with a very heavy thunderbolt, the situation was naturally a little different, the mud that people could easily pass through was deeply trapped in the wheels, and after four or five of the ten thunderbolts passed, it was difficult to move forward because the wheels of one car were stuck in the mud, so that Cao Zhang's team had to stagnate.

"Hurry up and pull that wheel out of the dirt!" Such a small change made Cao Zhang, who was in a good mood, a little anxious, and for a while his eyes were all attracted by the thunderbolt car that was deep in the mud, but he did not observe, nor did he find a tall reed bush not far from the edge of the mud and a small forest behind it.

Of course, the soil here was not enough to make the wheels of the thunderbolt deep into it, but Zhou Yu, who discovered this place, naturally knew how to create favorable conditions for himself, and after discovering Cao Zhang, who rushed here, Zhou Yu ordered someone to expand this muddy place several times, and the deep ditch that fell into the wheels was dug by the defenders of Jingzhou less than an hour ago, because it rained a lot in Jingzhou, and it just rained a little last night, so this situation did not attract Cao Zhang's attention.

When hundreds of Wei soldiers were struggling to pull out the thunderbolt cart stuck in the dirt, and most of the other Wei soldiers were also focused on this, what they didn't see was that the reeds and behind them were already several times their size, slowly closing them, and thousands of crossbows had been mounted with arrows and were aiming at their respective targets.

After a long time of incense, the thunderbolt stuck in the dirt still failed to pull out of the dirt, which made Cao Zhang a little puzzled in his heart, there was such a deep ravine on such a path, he couldn't help but want to go closer to take a look.

Cao Zhang's actions made Zhao Yun, who was already staring at him, make up his mind in an instant, he didn't want Cao Zhang to get close to the ravine and see that it was not formed by rain, and then remind the sergeant under his command. Their goal is very clear, that is, to catch Cao Zhang off guard.

Finally, with a gesture from Zhao Yun, without warning, arrows suddenly flew out from the reeds on the side of the Wei army......
