Seeing Cao Cao's cold and murderous gaze, his heart jumped, and he quickly retreated, and said in a deep voice: "Don't worry, the secret guards will not let you down!" ”

"Very good, you go down, this matter will be done immediately!" Cao Cao was undoubtedly very satisfied with Dark One's statement, nodded, waved his hand, and signaled that Dark One could retreat. "Yes, the subordinates are retired!"

"Slow!"

Seeing that Dark One bowed backwards and was about to leave, Cao Cao didn't know what he thought, and suddenly stopped Dark One with a voice, seeing his puzzled gaze, Cao Cao thought about it, a struggle flashed in his eyes, and then he firmly said: "You secret guards, not only to investigate Jinyiwei, but also Jia Xu, who is in charge of Jinyiwei and is in the position of the secretary of the Criminal Department, you also investigate Gu to see if he has collaborated with the enemy!" ”

Dark Yi's heart sank, he didn't expect that Cao Cao would even have to investigate Jia Xu, who was also the commander of the Jinyi Guard and the secretary of the Criminal Department, but through this, Dark One also understood very clearly that Cao Cao valued this time, and was unwilling to look up at Cao Cao, Dark One bowed his head, and after promising again, he got Cao Cao's order to let him retreat.

After the dark one retreated, Cao Cao, who was sitting alone on top of him, knocked on the desk and said softly with a disdainful expression: "Jia Wenhe, I hope you don't let Gu down, otherwise, Gu will naturally cry and kill Ma Yan!" ”

Jin Yiwei's dereliction of duty this time can be said to make Cao Cao very annoyed, if Xun Yu didn't happen to come to Youzhou, the sudden attack of the 50,000 Xianbei army is likely to affect not just Youzhou, but the entire north, as long as he thinks of this, the nameless fire in Cao Cao's heart has not been extinguished no matter what.

Similarly, Jin Yiwei's dereliction of duty this time made Cao Cao pay attention to some things that may have appeared inside Jin Yiwei, as a Jinyi guard who was investigating intelligence, Cao Cao absolutely could not allow the slightest problem to appear within it. This is the reason why Cao Cao ordered the secret guards, including Jia Xu, to investigate.

Ordering the secret guard to investigate the Jinyi Guard, it is inevitable that there will be some wrongful things, after all, it is just like the later generations of internal and external intelligence bureaus did not deal with it. Even the brocade guards and dark guards more than 1,800 years ago were the same.

However, compared to the internal problems of Jinyiwei, and the big problems that will occur in the director, some Jinyiwei who died unjustly, Cao Cao also turned a blind eye.

Of course, the reason for this. It's not nothing, so as to deter the idea of Jinyiwei, and there is that after this incident, Jinyiwei and the secret guard will inevitably become fire and water, and in the future, Cao Cao will control these two big killers, as long as it is appropriate, it will definitely be handy, and balance is the royal way of the emperor.

And the secret guards in Liucheng secretly left Liucheng in batches. When he went to the place where Jinyi Wei was located and began to investigate, Zhao Yun, who led 20,000 cavalry in Youzhou, finally arrived at Youbeiping County in Youzhou after several days of rapid marching.

"Phew, how long is it from here to the mound?"

"General Hui, Tuyin City is not far from here, and if you march quickly, it will only take about half an hour. If you march slowly, it will only take about an hour to travel. Looking at the scorching sun in the sky, Zhao Yun wiped the sweat on his forehead, and a Cao military captain behind him. Nor is it much better than Zhao Yun, and after calculating the distance from here to the mound with a tired look on his face, he replied.

Fatigue and fatigue are the most obvious appearance of the 20,000 cavalry at this time, and Zhao Yun, who saw this, thought that there was only one hour left, and his brows relaxed slightly. He said: "Tell the soldiers, as long as you hold on for another hour, after reaching the mound, the whole army will rest for a day!" ”

"Yes!" Although tired, as the elite 20,000 cavalry of the Cao army, they did not oppose Zhao Yun's order, but obeyed and drove the war horse under their crotch again and headed towards the direction of the city.

Because it was not the previous rapid march, it took a little more than an hour for the 20,000 cavalry to arrive at the mound, but in this way, the 20,000 Cao soldiers at least got a little rest.

However, just when Zhao Yun was about to lead his soldiers and horses into Tuyan City, a horn sounded, Zhao Yun's face changed, and he looked towards the place where the sound came from, only to see the dust billowing in the distance, nearly a thousand Xianbei cavalry without armor, waving the weapons in their hands, whining and screaming in the direction of Tuyan City, showing off their might under the city, and the Cao soldiers on the city wall, although everyone was out of the sheath and the arrows were wound, but there was no trace of soldiers and horses out of the city.

"General, looking at the clothes, I think it's a Xianbei barbarian army, and the Tu Yin Taishou doesn't know what he's doing, so he doesn't move!"

General Cao Jun looked at the Xianbei cavalry who were whining and howling, and his face changed, not only did he not expect that the Xianbei soldiers and horses had already arrived in Youbeiping County.

What made his face change even more was that as the county guard of Youbeiping County, and also the official of the Taishou City of Youbeiping County, He Qi's soldiers and horses did not make the slightest move, allowing the Xianbei cavalry to come and go, which made the general feel very aggrieved and angry.

"Don't make a conclusion about this matter for the time being, let's talk about the defeat of these Xianbei cavalry." Although Zhao Yun's heart was full of doubts, he still had a clear distinction between the main and the secondary, and the enemy was at present, even if the Tuyuan was too guarded and did not move, it was because he was weak and afraid of war, and he still had to deal with these Xianbei cavalry first.

"Ready!" Zhao Yun's spear was raised high, and the 20,000 cavalry of the Cao Army behind him bowed down one after another, grasping the reins tightly, and their eyes were also fixed on the spear raised by Zhao Yun in front of him.

"Kill!" Immovable as a mountain, aggression like fire, 20,000 Cao cavalry from extremely quiet to extremely moving, only in a moment, and the 20,000 Cao cavalry charge raised the dust and vibration, also let the Xianbei cavalry get a warning.

However, even so, it was useless, and it quickly hit the Cao cavalry a hundred steps away from the Xianbei cavalry, riding and shooting, returning fire, and returning the horse gun, after the three-plate axe of the Cao army's light cavalry was used one by one, the Xianbei cavalry, which was originally caught off guard, completely collapsed under the three-plate axe after firing a few rounds with the Cao cavalry.

The war started quickly, and ended very quickly, and when the Cao soldiers on the city wall came back to their senses, the Xianbei cavalry that was originally showing off their might under the city had collapsed, and on the battlefield, the Cao cavalry was divided into small teams, strangling the Xianbei cavalry back and forth.
