Li Qing'an ordered Yan Ming to lead 100 people to guard Jialan City. He led the remaining 400 people to go on the secret guarding passage and continue to march eastward. Ten days later, Gao Xianzhi's army also arrived at Jialan City.

In the palace of Jialan City, Gao Xianzhi was considering his next deployment in front of the map. He could directly attack Xiao Bolu from Chifotang Road, but the road was long and difficult, and the logistics of his 10,000 troops could not be solved.

More importantly, there are nearly 10,000 Tubo troops on Lianyun Castle. If they fight back to Xiaobo and attack Xiaobo's Tubo army from north to south, the Tang army will be in danger! Moreover, it is meaningless to seize Xiaobo's if they don't take down Lianyun Castle, but it is more important to take down Lianyun Castle. Ten thousand Tubos in the northern valley of Telmanchuan will have no way to support them. They will also withdraw Tubo and kill three birds with one stone!

Thinking of this, Gao Xianzhi used a charcoal pen to make a heavy fork on Lianyun Fort, but as planned, he divided into three groups to march into Lianyun Fort. He Chongyi, the commander of Shule Guard and Captain, led 3,000 cavalry along the north bank of Telmanchuan to march into Lianyun Fort, cut off the connection between Lianyun Fort and the Tubo army in Telmanchuan, and replaced the commander of Jia Chongsheng, and went south from Chifotang Road to block the Tubo army that might have retreated from Lianyun Fort. Gao Xianzhi took the middle road and left the Telmanchuan valley and walked into the secret passage to march into Lianyun Fort.

The next day, the three armies separated and rushed towards Lianyun Castle.

Li Qing'an was hiding during the day and walked for nearly twenty days. In the middle of the night, they finally arrived at Polechuan, fifty miles away from Lianyun Castle. Polechuan is one of the two tributaries in the upper reaches of the Wuhu River, one is Bomi River and the other is Polechuan. Lianyun Castle is close to the middle section of Polechuan.

After the march came here, Li Qing'an's mission was completed. He would wait for Gao Xianzhi's main force to arrive. In order not to be discovered by the spies of the Tubo army, the Tang army found a huge cave to hide.

The soldiers were exhausted and could finally rest well. Everyone lay down and fell asleep quickly. The cave was quiet, and the soldiers slept sweetly, and the snoring sounds one after another.

Li Qingan lay on a sunken rock, with a military blanket under him like a soldier, but he couldn't sleep. The moon rose, and the silver-white light shot into the hole and sprinkled on his face. For more than a year, whenever the moon rose, he would think of his previous life, and his memory of his previous life was pale. The high-intensity military training gave him a strong body. The rest was on an archery field, year after year, day after day, and he didn't even have a mobile phone. He would only enter the prosperous metropolis during the competition. Despite this, he still missed his previous life extremely.

Li Qingan sighed, and he gently stroked the long scar on his face. The scar had become his permanent symbol. He seemed to remember something and took out a small bronze mirror from his pocket. This was something Gao Wu threw to him that night. He thought that the stingy little girl would give him a knife and arrow, but unexpectedly it was a bronze mirror.

Thinking of Wu Niang's strange thoughts, Li Qingan couldn't help but feel a warm feeling. He looked at his face with a bronze mirror in the moonlight. The scars healed very well and could hardly be seen. Most of them were covered by their hair. They only pulled a short one on their foreheads to the tips of their eyebrows. However, this scar did not bring him a sense of hideousness, but instead added a hint of a man's coldness and hardness to him.

"General!" A low cry from the guard post came from the entrance of the cave.

"What's the matter?" Li Qing'an stood up and walked towards the entrance of the cave.

"It seems like the river water has changed."

Li Qingan was stunned and hurriedly followed the sentry to the river.

The Pole River has become wider in this area. The river is thirty meters wide, with a strong water flowing deep and violently. It can cross the river very narrowly, only two miles wide. In the rest of the area, the river water flows close to the cliffs.

If it were Li Qing'an's hundreds of scouts crossing the river, of course it would not be a problem. However, more than 10,000 main force of Gao Xianzhi's crossing the river would not be so easy. The key is that it is easy to be discovered by Tubo spies on the other side, so that the Tubo army can come to intercept it in time.

When Li Qing'an came to the river, he saw that the water level of the river suddenly dropped greatly. They walked into the river to measure the water level. The depth was less than three feet, and they could almost ride a horse to cross the Pole River. It turned out that the water level was at least two feet deep.

"What's going on?"

Just as I was confused, a rumbling sound of water suddenly came from the upstream, and a white line was seen galloping like thousands of horses.

"It's going to rise, run!"

Li Qing'an and a few sentrymen ran desperately towards the shore. As soon as they climbed ashore, the water whizzed past and the water level immediately returned to its original state.

Li Qingan sat on the ground and cursed: "His grandma, I'm so busy that I'm urinating."

"General, one stick of incense!" A sentry panted: "The water level has only been reduced for one stick of incense. It's strange, for some reason."

Li Qingan was also puzzled. It was really strange that this river actually had regular water level changes.

He pondered for a moment and said, "Let's observe for a few more days. There is still this secret to other soldiers. If you dare to disclose it, I will kill you."

Several sentries responded quickly: "Don't worry, General, we will never dare to disclose it."

Li Qingan observed for five days and found that it was indeed like this every day. The river water suddenly dropped at the fourth update, and only lasted for one stick of incense, which was very short.

Three days later, on the eighth day of the seventh month, Gao Xianzhi's main force arrived at Li Qing'an and his camp. Due to Li Qing'an's exploration of the road ahead, their march was very smooth and they arrived near Lianyun Castle on time.

Gao Xianzhi had eight thousand main forces, and Bian Lingcheng, the military supervisor, also came with the main forces. In addition to the five thousand Tang troops, there were also three thousand coalition forces that concealed the country and protected the secret country. However, after nearly two months of trekking, Bian Lingcheng was not able to withstand the fatigue and altitude sickness.

As soon as the main force of the Tang army arrived, the cave became a temporary command post. An oil lamp was lit in the cave, and the wicks were shaking suddenly. The dim lights were bright and dark. Gao Xianzhi was scrutinizing the map on a flat stone. Behind him were more than a dozen Anxi military officers.

After a long time, Gao Xianzhi sighed and said to Modao Captain Li Siye: "The difficulty in expeditioning to Xiaobolu lies in the dangerous mountains and rivers. How to cross the Pole River is my first worry. I have thousands of people crossing the river, and the momentum is so great that I will be discovered by Tubo spies on the other side, so that they will be intercepted and killed by me halfway. But if there are few naval troops, I am afraid that they will not be a match for the Tubo people. It is a dilemma!"

"Supervisor Gao, why not let our Modao Army cross the river first, and can resist the interception of the Tubo people."

Gao Xianzhi shook his head, "You Modaojun are full of heavy armor, so how can you cross the river easily?"

Don’t give Xi Yuanqing aside and say, “Supervisor, let me cross the river first.”

"Ship, let me cross first!" The fan general He Lou Yurun was not willing to fall behind.

"Don't fight, you all want to cross the river together." Li Qingan, who was standing in the back row, interrupted the dispute with everyone with a smile. Gao Xianzhi glanced at him, and saw that his eyes were full of confidence, and he couldn't help but move, thinking, "He is the scout first, and he must have discovered something."

"Qiro, what advice do you have?"

Li Qingan walked up and said a few words in Gao Xianzhi's ear. Gao Xianzhi was shocked and nodded and smiled at everyone, "Everyone, go and rest! I naturally have a way."

Everyone was talking and dispersed in disarray.

At the fourth update, Gao Xianzhi brought several personal soldiers to the Polechuan with Li Qing'an. They tied a big stone with a rope and threw it into the river. The big stone was suddenly washed away more than two meters away. It can be seen that the undercurrent is turbulent below, and the river is 15 meters deep. Gao Xianzhi couldn't help but frown. He still didn't believe what Li Qing'an said.

"Look at the Grandmaster!" A soldier screamed in surprise.

The river water changed rapidly and the water level dropped sharply. In a moment, you could see the big stone on the riverbed. Gao Xianzhi was stunned and looked at the scene in front of him incredibly.

Suddenly, he knelt down and raised his head and said, "Oh my God! Are you going to help me succeed?"

After a stick of incense, the river suddenly surged and quickly returned to its original position. Gao Xianzhi laughed proudly. With this help from God, why worry about the Tubo army not breaking?

"Ship Gao, I have a suggestion for this matter." Li Qingan said with a smile.

Gao Xianzhi had extremely trust in Li Qing'an at this time, and he said without hesitation: "You said!"

"Master, the most important thing about fighting between the two armies is morale. Why don't Master use this matter to boost the morale of the army?"

Gao Xianzhi nodded when she stroked her beard and nodded. Li Qing'an's suggestion came to his heart.
