The mountains are magnificent and the three servants are closed, the gates are connected to Jiuzhou, the river flows from Shaanxi Road, and the river flows around Huayin.

It is for Tongguan.

The north of Tongguan City is surrounded by the Yellow River, and the southeast of the city is surrounded by mountains, making it impossible for the enemy to encircle it. The living facilities in the city should be complete. The Tonghe River, which passes through the city, provides sufficient water for Tongguan and has enough fields to plant crops. Even if the city is besieged, it is difficult to get rid of ammunition and food.

Tongguan carries two capitals on one shoulder, one side is Luoyang and the other side is Chang'an. It can be said that it is overwhelming. Once it is lost, Chang'an will inevitably be insured. It is also known as the first level in the world.

Now, the Liang army led by Cao Xuan is making a final resistance against the Tang army in Tongguan.

It can be said that once Tongguan is defeated again, the collapse of Daliang will be a foregone conclusion.

The Tang army has been in Tongguan for nearly a month. For the past month, You Yong has been careful and has not done his best to attack at all costs. This is certainly because Tongguan is naturally dangerous and difficult to capture, and it is also because the Tang army has always paid great attention to reducing the casualties of soldiers. Without the necessity, it rarely uses the lives of soldiers to accumulate victory.

Even so, Cao Xuan felt great pressure.

The most important thing is the decline in morale.

Changyuan was defeated, Hulao was defeated again, and most of the elite troops of the Liang army were lost, which had already made the morale of the Liang army extremely low.

With the Zhenzhou Incident and the establishment of the Guangzhou court, the war of words in Wuyi and Guangzhou formed in actual military confrontation. Li Ze helped the coffin of the Supreme Emperor to come south, and Cao Xuan's pressure suddenly increased several times. You Yong no longer pity the lives of the soldiers, but launched a crazy attack on Tongguan.

Even in the bad weather with rain and snow, the Tang army never gave up on the attack.

Even in the dark, the Tang army's catapult never stopped bombarding.

This made the Liang soldiers guarding the pass extremely tired.

Because the Liang army had completely lost the courage to fight against the Tang army, they were trapped in Guanzhong and could only passively wait for the Tang army's attack. The Tang army's attack was time-consuming. Often, when you seemed impossible, you suddenly launch a rapid attack. If you are not interested, you will fall into a state of doom.

The psychological and physiological double pressure has made Liang Jun in Tongguan dynasty brink of collapse.

"Master General, today the Tang army launched a fierce attack on Jindou Pass." General Cong Xin walked to Cao Xuan's side. The other party was standing at the top of the city, looking at the road entering Tongguan.

Five miles away is where Cong Xin mentioned Jindou Pass is located.

Jindou Pass is not in Tongguan City, but three miles outside Tongguan City is a tall and lonely castle. To the north is the surging Yellow River and to the south is the towering Niutou Park. The road to entering Tongguan passes through here, the real Tongguan gate. The road to entering and leaving Tongguan is squeezed in the middle by the surging Yellow River and the high plateau. The terrain is extremely dangerous and the road is narrow, so a single carriage can barely pass through.

The reason why it was built like this was naturally for military needs. From here to the east gate of Tongguan, it is five miles long and is called the "Five Miles Secret Gate". A truly one man is at the pass, and ten thousand men cannot open it.

If the Tang army wants to capture Tongguan, they must first win Jindu Pass.

If the Liang army lost Jindou Pass, it would be equivalent to losing Tongguan.

"How are the casualties in Jindu Pass?" Cao Xuan asked in a deep voice.

"In today's battle, hundreds of casualties!" Cong Xin said: "Master, a group of people must be added to go in and withdraw the wounded soldiers at the same time. Where are the wounded soldiers? It's too harmful to morale."

Cao Xuan nodded: "Another five hundred soldiers will be added. The required materials will be transported in after dark. Tell Cao Zhen that the safety of Tongguan and the gains and losses of Chang'an are all tied to him."

Cao Zhen is Cao Xuan's eldest son and a general guarding Jindou Pass.

"The young marshal is extremely brave and has many wisdom and tricks. There will be no mistakes in Jindou Pass!" Cong Xin said.

Cao Xuan had no words. Speaking of courage, how many people in the Daliang army could surpass Xu Chao, the son of Xu Fu? In the battle of Changyuan, Xu Chao died on the spot.

Unfortunately, what else can be done except fighting to the death?

"Master General, there is an envoy coming in Chang'an!" An officer trotted up the city wall and said to Cao Xuan.

Cao Xuan nodded and said to Cong Xin: "You continue to check the defenses of various parts of the wall, and at the same time, you must check the military camps, warehouses and other places one by one, especially pay attention to the food of the soldiers. At this time, a little bit of Mars may cause major events."

"Don't worry, Marshal, at this time, everyone knows the severity of the matter, so there will be no problems with this." Cong Xin said.

"Be careful. The Tang army has made many tricks. In Hulao Guanzhong, General Xu was forced to fight and was annihilated by the Tang army in one battle. The old story of Tongguan should never be performed again." Cao Xuan sighed.

Cong Xin nodded repeatedly.

In the Battle of Hulao, the Tang army used the attacking plan to completely lose the fighting will of the Liang army in Hulao Guanzhong, forcing Xu Fu to lead the army to attack, and eventually fell into the trap of the Tang army, and tens of thousands of troops were destroyed in one go.

When he returned to the pass and saw Sun Tonglin, Cao Xuan was shocked. After hearing Sun Tonglin’s incident about Sheng Zhonghuai, Cao Xuan fell into a long silence.

Sun Tonglin was not rushing, but quietly waited for Cao Xuan to make a decision.

"So, Your Majesty has already taken care of it?" Cao Xuan spoke in an unknown amount of time, his voice was extremely low.

"Yes." Sun Tonglin nodded: "The current plan is almost over. This is the last little vitality and must be firmly grasped."

"At this time, the army entered the Qinling Mountains, how many people could go out?" Cao Xuan clenched his fists and roared in a low voice.

"Your Majesty only took the most elite 50,000 people away. It was divided into five routes and walked the five routes of the Qinling Mountains. Cao Bin had already set out to prepare." Sun Tonglin said: "The rest of the people can only give up."

"Fifty thousand people?" Cao Xuan lamented: "Are you going to give up here in Tongguan?"

"Your Majesty needs time, and Tongguan needs to resist until the last moment to buy enough time for Chang'an's retreat." Sun Tonglin said: "At present, there are only a handful of people who know about this matter. Even the troops that have already set out only think that they are leaving the city and preparing to reinforce the front line to resist Tu Lichun and Wang Sili's army. It is only at the last moment that the generals will receive the order to turn around and enter the Qinling Mountains."

Cao Xuan lowered his head and said for a while: "How long will it take?"

"The longer the better. The longer the time, there will be more materials in Chang'an and more effectively support the soldiers to walk out of the Qinling Mountains. Of course, Your Majesty said that when it is absolutely necessary, please be sure to escape from danger and rush to meet with him. Even if the army and horses are lost, it doesn't matter. As long as you leave the Qinling Mountains, everything can be started over again."

Cao Xuan smiled miserably: "Where can we start over again? I'm afraid that what I lost will never come back."

"Master General!" Sun Tonglin said: "Yizhou's natural danger, the country of Tianfu, is not without the opportunity to regain its glory."

Cao Xuan nodded. From a rational point of view, Zhu Youzhen made this decision. The path planned by Sheng Zhonghuai for him is the best way out now. But emotionally, he really couldn't accept it.

"I understand. Go back and report to Your Majesty, Cao Xuan will definitely fight to the last moment." He said a little lonely.

Sun Tonglin nodded: "Mr. Marshal's family, Your Majesty will take care of himself. There will be no mistakes along the way. Please rest assured. I wonder what else does the Marshal need Sun to tell His Majesty?"

"No more!" Cao Xuan shook his head, "It's up to people to succeed, and it's up to heaven. I hope we can withdraw from Qinling Mountains smoothly and start over in Yizhou!"

Sun Tonglin did not stop for a long time and immediately said goodbye and left.

Cao Xuan sat in the room and did not get up for a long time.

He and his army were all abandoned in Tongguan.

They must become the last line of defense for Zhu Youzhen to evacuate Chang'an. Although Zhu Youzhen only brought the most elite 50,000 troops away, it is conceivable how difficult it is to enter the Qinling Mountains under such weather.

"Old Zhu, that's all I can do for your old Zhu family. It seems that I will be able to reunite with you soon." Cao Xuan sighed: "But you were killed by your son, and I don't know if you have the face to see me. At least half of the good situation is destroyed in your own hands. You will never control your thing in your life, and in the end, it will be destroyed in your thing!"

When talking about this, Cao Xuan was very angry. If Zhu Wen had not occupied his daughter-in-law, if Zhu Youyu had not killed his own son, even if there was still a fight between his brothers, as long as Zhu Wen was alive, everything could still be controlled.

"Bastard!" He stood up, picked up his knife and walked out. He scolded him, but he didn't know who he was scolding.

After the Tang army camp failed again and again, You Yong looked at the towering Jindou Pass opposite, which had the world's number one level, and was filled with sorrow.

This damn pass can only be used to unfold so many people at once, and even heavy catapults and other weapons can only be placed on two at a time. The most taboo tactic of adding fuel to war has become the only choice here.

"Shi Zhuang, tell me, what else can I do?" You Yong turned his head to look at the number one fierce general of the Tang Dynasty.

"There is no choice but to fill in the life!" Shi Zhuang spread his hands.

"The King of Qin has arrived in Luoyang and will be able to arrive at us for half a month at most. If we haven't taken Tongguan yet, it would be embarrassing."

"I'll try again in the afternoon!" Shi Zhuang said: "The world's number one level is not that easy to fight. Now Liang Jun is desperate. The rabbit is still biting people when he is anxious, let alone people?"

The two looked at each other, and both shook their heads helplessly.

"The two generals, Zhu Yizhu, are in charge, please go back to the camp immediately."

"Who?" You Yong asked.

"Zhu Yi, Zhu Du is in charge!" said the man.

You Yong was a little unfamiliar with this person, but Shi Zhuang heard it and raised his eyebrows. Zhu Yi was specifically responsible for the research, development and production of some extremely secret weapons within the Tang Dynasty. Could it be that his arrival was something new?
