'Boom...... Boom......'

The nine huge stones gathered in the middle of the camp of the Wei army after a while, and suddenly, one after another Wei troops died tragically under the attack of the boulders, and the round boulders did not stop after they landed, but quickly rolled forward in the flat Wei army camp, this rolling, the casualties caused to the Wei army were more huge than these boulders falling.

For a while, the Wei army, who didn't know what was happening, all stood up and fled in all directions, and Sima Yi wanted to order the soldiers to gather together, but it was already a little too late.

Zhou Yu and Zhao Yun, who had seen the power of the thunderbolt for the first time, were also shocked by this result, they knew what kind of consequences such a boulder would be if it smashed on the city walls and gates of Shangyong, and now, fortunately, such a heavy weapon was already in their hands.

After the blow was hit, Zhou Yu and Zhao Yun naturally would not stop their attack, the nine boulders did not cause great damage to the Wei army, but the biggest effect was to make the Wei army very chaotic, they did not act according to Sima Yi's instructions, but ran in all directions, obviously, the pressure caused by these boulders to the Wei army was too great.

Soon, under the guidance of the craftsmen, a second boulder was projected from the nine thunderbolts, which were called thunderbolts precisely because of the sound of the stones fired like thunderbolts, and now, these thunderbolts were like death in the ears of the Wei army, and as soon as they heard this sound, they knew that the unavoidable boulders were about to reach their heads, and where they landed, they had to resign themselves to fate.

Under this reciprocating cycle, Zhao Yun launched five huge stones on the thunderbolt car half a mile away from Sima Yi's camp, and forty-five boulders destroyed the Wei army's camp to the point that it was not in shape, and the Wei army resting in the camp also lost at least 10,000 yuan, among which there were really not so many who died under the boulder, and most of the Wei troops died under the trampling of the robes on their sides.

Finally, Sima Yi, who had gathered twenty or thirty thousand soldiers with difficulty, was surrounded by Zhang Liao, Li Dian, Le Jin and others, and rushed straight to the location of Zhao Yun and Zhou Yu to kill him, although Sima Yi did not know how these thunderbolts that he secretly prepared arrived in the hands of the Jingzhou defenders, but he knew that he could no longer sit in the camp at this time, although he did not know the number of enemy troops, but at this time, only by impacting the enemy's approach could those thunderbolts be ineffective, otherwise, These Wei troops will still be a live target for the thunderbolts.

However, the result of such a hasty response was that the forty or fifty thousand Jingzhou defenders who rushed out behind the Jingzhou sergeants who pretended to be Wei soldiers rushed out and fought with the Wei army.

This chaos made the original numerical advantage in the Wei military camp completely unable to give full play, but fell behind because of the hasty response to the battle.

Even though the situation suddenly fell to the bottom, Sima Yi did not panic, he knew that when Cao Zhang's whereabouts were unknown and his life and death were uncertain, if he messed up again, then this war to capture Jingzhou would be completely defeated, and the final outcome would not be much different from Yang Xiu.

So Sima Yi ordered Le Jin, Li Dian and others led the army here to resist this wave of Jingzhou soldiers who broke into the Wei army camp, and on the other hand, it was strictly forbidden for everyone to inform Xu Chu who was trying his best to attack Shangyong City of this news, according to Sima Yi's previous prediction, even if there was no thunderbolt, Xu Chu could break through the gate of Shangyong in one or two days, as long as the gate of Shangyong could be broken, then no matter how this time he sent troops he was meritorious.

But Zhou Yu had already planned in the face of this situation, he saw that Sima Yi personally led the army to fight with his Jingzhou sergeant, and he had the intention of resisting to the death, so he hurriedly summoned a deputy general in the armor of the Wei army to his side, whispered in his ear, and the deputy general bowed his head again and again when he heard the words, and then waved his hand and took two people who were also wearing the armor of the Wei army, all the way to the south.

Zhou Yu's small move did not attract Sima Yi's attention, and after the deputy general left the battle group, he took off the white silk on his arm and put it into his shirt, no different from an ordinary Wei army soldier.

The destination of these people is exactly where Xu Chu, who is attacking Shangyong, is. Because there is still some distance from the Wei army camp, and Xu Chu's all his attention is focused on capturing Shangyong, so he did not notice the changes in the Wei army camp behind him, if under normal circumstances, Sima Yi did not come to inform Xu Chu of what happened in the camp, Xu Chu would definitely continue to attack the city, but this thing that Sima Yi did not do, Zhou Yu did for Sima Yi.

It didn't take long for the Jingzhou sergeants wearing Wei army armor to arrive at Xu Chu's place with a disgraced face, Xu Chu saw that his soldiers and horses were so anxious to come from the direction of the camp, his heart sank, and before the sergeant could speak, he asked sharply: "What's going on in the camp, why are you like this, tell me quickly!" ”

The sergeant first took a few breaths, and then replied eagerly: "I don't know why, a team of Jingzhou soldiers and horses actually captured the thunderbolt of my Wei country, and suddenly attacked the camp, under the attack of the thunderbolt, our army camp is already in danger, General Zhong Da sent me to ask General Zhong Kang to return to the camp to rescue quickly, if I go late, I am afraid that the sergeants in my camp are in danger of being wiped out!" ”

Such words are like thunder in Xu Chu's ears, Wei has such a siege weapon as a thunderbolt, Xu Chu, who followed Cao Cao in the early years to fight in the south and the north, is naturally well aware, and he has also seen the power of the thunderbolt, although he does not know the cause and effect of hearing this, but he has no doubt in his heart.

At this time, it was a good time to attack the city, Xu Chu had already seen the fatigue of the Shangyong defenders, and he even felt that he could break through Shangyong with such strength in less than ten hours, but the camp was broken, and the marching commander Sima Yi sent people to ask for help, this matter was naturally not trivial, although Xu Chu felt very sorry in his heart, but he still had to grit his steel teeth and give the order to withdraw to the camp.

The Wei army, which was still attacking bloodily one moment, retreated from the city like a tide the next moment when it received Xu Chu's order, which was without warning, and it was also a situation that had never occurred in the past four days.
