The attack just now took most of the day, and the result of Cao's army was very small, only shooting more than a dozen Black Scale Army soldiers to death. Apart from that, no results were obtained.

On the contrary, Liu Zhe gained considerable results. Several ladders were destroyed or abandoned, and a well railing was destroyed. More than half of the archers on it were killed or injured. In addition, the damage of the attacking infantry, Cao Cao lost nearly a thousand soldiers in one afternoon. (To prevent readers from misunderstandings, let me explain here that casualties, including deaths and disabilities, not all of them were dead.)

Even though Cao Cao had an army of 60,000, his heart was so painful. He lost 1,000 in one afternoon, and then he might lose two or three thousand soldiers in a day. As long as he fought for a few days, Cao Cao would have no soldiers available.

Cao Cao directly ordered the attack to be suspended, let the soldiers rest and repair, and continue the attack tomorrow.

At night, Cao Cao pulled a group of his subordinates to see if there was a better way to capture Tongguan. As a result, he discussed for one night that there was nothing except that many people gained a dark circle. Facing a strong pass like Tongguan, there was no other way except for a strong attack.

So early the next morning, after Cao Hong received the order, he continued to lead his troops to attack.

Faced with the return of Cao's army, Zhao Yun commanded the Black Scale Army to respond calmly, but today the Cao army's attack increased, and they continued to attack the city wall. The ladder was pushed down and rebuilt, and the ladder was smashed and replaced with a new one.

Such repeated impacts greatly increased the pressure of the Black Scale Army on the city wall. In the end, they had to use tincture oil, pour the tincture oil on the cloud ladder, and burned all the ladders.

The raging fire forced Cao's army to retreat. Although it repelled Cao's army's attack, Zhao Yun had no joy on his face. This was just the beginning. Moreover, there was not much turbid oil in Tongguan City. If you use some, you would have less and you could not replenish it.

After the fire below the city wall was extinguished, Cao's army continued to attack. Cao Cao planned to attack the city day and night so that Liu Zhe's men would have a chance to breathe.

Cao Cao looked at Tongguan, and his soldiers crawled onto the city wall in a dense manner, and a sneer appeared on the corner of his mouth: "A mere 20,000 people, as long as he attacked day and night, I don't believe how long they can last. What's more, Zixiao has arrived, right?"

Although Tongguan is in Liu Zhe's hands, it cannot completely lock up the contact between Cao Cao and Cao Ren. The messengers they sent over mountains and rivers could still send the message to Gong Wan.

Cao Ren has sent someone to send news that his army is already on the road. Now, it should be almost here.

Mao Jie nodded and agreed: "At that time, the attacks between the two sides will be close to 150,000 troops, and they will take turns to attack. Liu Zhe's men can only be exhausted and will definitely not be able to resist."

"Hmph, Liu Zhe will definitely regret it." Cao Cao snorted coldly.

He looked at Tongguan coldly, wishing to capture Tongguan immediately, arrest Liu Zhe, and then deal with him well.

At this moment, Cao Cao's eyes suddenly subsided, and in the distance, behind Tongguan, a ray of smoke rose up.

Seeing the wolf smoke rise, Cao Cao was immediately overjoyed and laughed loudly. This was the signal agreed between Cao Ren and Cao Cao. As soon as Cao Ren arrived, he would ignite the wolf smoke and tell Cao Cao on the other side.

"Haha, Zixiao is here, Liu Zhe, I see what you can do this time."

"Light the wolf smoke and pass the order. Two days later, the entire army will attack, cooperate with Zixiao, and attack on both sides..."

......

There was a wolf smoke in the west of Tongguan. Needless to think about it, it was the enemy's reinforcements coming, and Zhao Yun's face became even worse.

Just dealing with Cao Cao's attacks was already a little stressed, and an enemy came on the other side, and both sides had to deal with the enemy's attacks, and the pressure suddenly increased greatly.

The enemy has not yet arrived to attack, but Zhao Yun has already felt the pressure.

"Lord, Cao Cao..." Zhao Yun went to find Liu Zhe, but before he finished speaking, Liu Zhe knew.

When Liu Zhe knew that the enemy was coming to reinforcements, there was no surprise on his face. He seemed to have expected that the enemy would come from the other side in the morning.

Liu Zhe smiled at Zhao Yun and said, "Don't worry, I already know."

Cao Ren's appearance was completely unexpected by Liu Zhe. If Cao Ren didn't come, he would be surprised and worried.

Seeing this, Zhao Yun couldn't help but ask: "Lord, did you know it long ago?"

Seeing that Liu Zhe's face was normal, he subconsciously relaxed. Since Liu Zhe guessed it early in the morning, there must be a trick.

The reason why Zhao Yun was so worried was that he was worried about Liu Zhe's safety, fearing that Tongguan would be in trouble and endanger Liu Zhe's safety. However, now seeing Liu Zhe's expression, Zhao Yun was not worried. If Liu Zhe had a backup plan, then Cao Cao would be the one who suffered, and it would not be Liu Zhe.

Seeing that Liu Zhe was confident, Zhao Yun felt relieved. He did not ask. Now his first priority is to defend Tongguan. He saluted Liu Zhe and said, "Since that's the case, lord, then Zilong will go down."

"Yeah!" Liu Zhe nodded, but soon he spoke to Zhao Yun again: "Zilong, please leave me a thousand cavalry, don't let them go up to defend the city, let them raise their energy and save their strength. I have my own use."
