Sima Yi quickly came to see Cao Cao.

"King, Liu Yu is afraid that he would attack Luoyang, but in order to sneak attack Bingzhou and then capture the strategies of Hebei such as You and Ji!" Sima Yi is indeed a genius who is almost the same as Zhuge Liang. He has seen through Liu Yu's strategy.

Cao Cao was shocked when he heard this: "What! Is this really the case?"

After Sima Yi explained, Cao Cao felt a cold air soaring into the sky.

Cao Cao said anxiously: "According to what you said, Liu Yu should have more than 350,000 troops to attack us, but there were only 300,000 troops to go east to Tongguan, and another Qin army of about 50,000 troops to attack Luoyang, which was a feint. One was to cover the 50,000 Qin army of unknown destination, which was sneak attacking Bingzhou, thinking that it would then capture the bridgehead of You and Jizhou. The other was to plot against this king in order to protect Luoyang, and to continuously dispatch troops from all over the place to reinforce, including Hebei, Kongxu, the defense of Hebei?"

Sima Yi confirmed: "King, I think so."

Cao Cao opened his eyes and Luoyang had been fighting for several days. He had ordered that 20,000 soldiers be transferred from Hebei to the south. Don't underestimate these 20,000 soldiers. You must know that the three states of You and Ji are only 150,000 soldiers defending Cao's army, of which 60,000 are guarding Yuan Shang, Yuan Xi and Wu Heng in Youzhou, and they are not easy to move. There are only 90,000 soldiers in Hebei, and now 20,000 soldiers are transferred to Luoyang. Now there are only 70,000 soldiers left in Hebei, and 20 counties, each county has less than 4,000 soldiers to defend. What a weak defense.

Cao Cao said anxiously: "I will immediately inform Yu Jin from Bingzhou, and also order the troops to return to Hebei."

Sima Yi shook his head and sighed, "King, it's probably too late. At this moment, the 50,000 Qin army must have entered Bingzhou."

...

As Sima Yi thought, the battle in Luoyang had been going on for ten days, and on the ninth day, another 50,000 Qin army led by Zhao Yun and Zhang Xiu had completed the detour from Hetao to the south of the Mosun and rushed to the bottom of Yanmen Pass.

Zhao Yun took the lead in white horses and silver spears, and behind him were Zhang Xiu and 50,000 Qin troops.

There were only five thousand Cao's army guards at Yanmen Pass, and the commander was a general named Chen Tong.

"Enemy attack! Enemy attack!" The city gate was in chaos.

Since Yanmen Pass is usually to prevent the Xianbei barbarian cavalry from hitting Caogu, the gate of the city pass has always been closed. Although Zhao Yun, Zhang Xiu and other Qin troops arrived suddenly, it was impossible to rush into Yanmen Pass directly.

At the city gate, Chen Tong was shocked at first. Seeing that it was not the Xianbei barbarian cavalry, but the armor of the Qin army in Guanzhong. He asked loudly: "Who is the commander of the Qin army at Guanxiu? Why did he attack my Yanmen Pass?"

Zhao Yun pointed at Chen Tong with a silver spear and shouted: "I am Zhao Zilong, Changshan, and General Cao is closed. If you don't turn on and surrender quickly!"

Chen Tong was shocked. It was Zhao Yun, the second strong general in the world? However, Chen Tong was loyal to King Cao Cao of Wei, and it was absolutely impossible to ask him to turn on and surrender. So what about Zhao Yun? Zhao is a hammer.

"Rebels in Guanzhong, go and die!" Chen Tong not only did not surrender, but also bent his bow and arrow, shouting angrily and shooting at Zhao Yun under Guan.

Zhao Yun turned his head and dodged the arrow that Chen Tong shot at him. Then Zhao Yun was furious. He quickly pulled out the horse-side bow and arrow and shot Chen Tong with a quick arrow. Chen Tong could not dodge and hit his right shoulder and was injured.

The city gate suddenly became in chaos.

"Kill!" Zhao Yun took the opportunity to order the Qin army to start attacking the key points.

Among the 50,000 Qin troops, 20,000 were the most aggressive soldiers who returned from the battle of Yizhou. They carried a large number of siege equipment such as cloud ladders to launch the fiercest attack on Yanmen Pass.

After three hours of the battle, Yanmen Pass was defeated. Five thousand Cao's army was killed and three thousand injured, nearly a thousand captured, and the remaining two or three hundred fled to Yanmen County with Chen Tong.

The Yanmen Pass was captured and the Bingzhou gate was opened.

Zhao Yun and Zhang Xiu went south without stopping, quickly captured the entire Yanmen County and killed Chen Tong.

Afterwards, Zhao Yun and Zhang Xiu continued to attack other Bingzhou counties and counties southwards.

There are six counties in Bingzhou. In addition to Yanmen County, there are five counties including Xingxin County, Taiyuan County, Hexi County, Leping County, and Shangdang County. The population is not large, and the total population of the six counties is only more than 400,000.

The Cao army garrisons in the six counties together were only 40,000, of which 7,000 were in Yanmen Pass and the entire Yanmen County, 20,000 were in Hexi County, and the other four counties including Taiyuan, Shangdang, Leping, Xingxin, etc., were only 13,000 Cao army.

Zhao Yun and Zhang Xiu left 7,000 Qin troops in Yanmen Pass and Yanmen County. In addition to other casualties, 40,000 Qin troops headed south from Yanmen County.

"Kill!" One day later, the gate of Xingxin County was knocked open, and Zhao Yun and Zhang Xiu rushed into the city one after another.

After capturing Xingxin County, Zhao Yun and Zhang Xiu continued to lead the Qin army south to Taiyuan County.

As the largest county in Bingzhou, Taiyuan County should have the largest number of defenders, but Hexi County is close to the east bank of the Yellow River and is the front line to prevent the Qin army from crossing the river to attack Bingzhou in Hetao area. Yu Jin and 20,000 Cao troops were all in Hexi County. In fact, Taiyuan County only had more than 4,000 Cao troops, even Yanmen County was inferior to Yanmen County.

When Yu Jin from Hexi County learned that Zhao Yun, Zhang Xiu and other 50,000 Qin troops detoured the south of the desert and attacked Yanmen Pass, Zhao Yun and Zhang Xiu had already captured Xingxin County and were about to kill to the foot of Taiyuan County.

Yu Jin was shocked: "What? The Qin army actually detoured from the south of the desert and attacked Yanmen Pass. Yanmen County was lost?"

"Xingxin County seems to be difficult to protect, and Taiyuan County cannot be lost. Otherwise, the three counties of Hexi, Shangdang and Leping will not be protected, and the entire Bingzhou will be lost." Yu Jin did not dare to slack off, leaving only two thousand Cao troops to guard Hexi County, and led the remaining 18,000 Cao troops to quickly support Taiyuan County.

As soon as he left Hexi County, Yu Jin received news again, Xingxin County was also lost, and the Qin army immediately came to Taiyuan County.

"We must arrive in Taiyuan County before the Qin army." Yu Jin was shocked and ordered a quick march as quickly as possible.

More than one hundred miles north of Taiyuan County.

About 35,000 Qin troops including Zhao Yun, Zhang Xiu also marched rapidly at the fastest speed.

Zhao Yun said: "As long as you take down Taiyuan County, Bingzhou will be more than half, and you will be able to capture the entire Bingzhou soon! In order to kill the Taiyuan County before the ban, General Zhang, I will lead the cavalry first, and you will lead the infantry later."

Immediately, Zhao Yun led 20,000 Qin cavalry to go first.

All the generals under Liu Yu, Zhao Yun, who led the cavalry to raid, had better ability than Lu Bu and Ma Chao.

Finally, Zhao Yungan arrived at the foot of Taiyuan County before Yuqian.

On the tower of Taiyuan County City, the Cao army general looked at Zhao Yun and other Qin troops who were rushing to the city quickly, and panicked. Fortunately, the city gate was closed in time and Zhao Yun did not let him directly enter the city.

At this time, on the northwest side of Taiyuan, a flag of Cao's army also appeared.

"It was General Yu Jin who has arrived!" said excitedly.

Zhao Yun also found that Yu Jin was waiting for Cao's army to arrive. He smiled disdainfully, and Yu Jin was finally one step later than him.

One step is a dead end!

Zhao Yun ordered the deputy general around him: "You will take three thousand cavalry here to monitor Taiyuan City and wait for me to lead other soldiers to defeat Cao's army."

After saying that, Zhao Yun led the remaining 17,000 Qin cavalry to the west, trying to defeat the Cao army of the forbidden army.
