Ten thousand Han cavalry, led by general Pang De and deputy general Leng Bao, rushed towards Hehuang. The cavalry brigade ran on the dark night, stirring up rolling yellow dust on the official road. Only by marching at night would it not be too eye-catching. The cold moonlight shone on the soldiers' armor, with a cold metallic luster, one team after another, as if a torrent of steel was rushing to the west.

This cavalry had just returned from Hefei. Before he could enjoy the glory of victory, nor did he have time to reunite with his family. He went on his journey again to the soon-to-divided Hexi.

Before the cavalry, the soldiers of the Five Eagle Strike Army set out in advance and rushed to Dadoubagu. Once the Dadoubagu is really occupied by Ma Chao's army, the steep terrain is not something that can be conquered by the cavalry, but special troops must be used to have hope. The special forces of the Han army are the Eagle Strike Army.

In fact, Dadou Bagu itself is under the jurisdiction of Hexi, and one general led a thousand soldiers to garrison, all of whom were Ma Chao's subordinates. However, Liu Jing didn't know whether the garrison and garrison were replaced by Qiang soldiers. Once replaced, the situation they faced would become complicated. They had to attack the valley entrance, and they could not let Hexi know, otherwise Ma Chao would take action in advance.

A few days later, the cavalry brigade entered Longxi County, not far from Dadoubagu. At this time, the soldiers of the Five Eagle Strike Army had arrived at their destination. They were hiding in a valley about twenty miles away from the entrance of Dadoubagugu.

Deputy General Ren Ping led more than ten people to investigate the news. The rest of the soldiers drank water and ate dry food in the canyon, and seized time to rest so that they could maintain their full physical strength at any time. This army had already been in battle and did not need to give instructions. He knew what he should do.

The main general Liu Zhengze sat on a big rock, waiting patiently for Ren Ping's news. At this time, a low and rapid run came. More than a dozen war horses wrapped in thick linen on their hooves had already rushed into the valley entrance. Deputy General Ren Ping and the others were back, and there was a cloth bag behind one of the war horses.

Liu Zheng was excited and jumped off the big stone and met him, "How is the situation?"

“As His Highness worried”

Ren Ping replied in a deep voice. He turned around and waved his hand. Two soldiers carried the big cloth bag over, unzipped the rope, and tied it with both hands and a soldier with a threadbae blocked in his mouth appeared in the cloth bag. Judging from his appearance, he was obviously a soldier from Qiang.

"This is a patrol soldier at the valley entrance. We are caught by us. He will tell the general all the information."

Liu Zheng pulled out the dagger and picked the linen from the soldier's mouth. The sharp blade pointed to the soldier's neck. Liu Zheng asked coldly: "How many Han soldiers are there in the Dadou Valley?"

Liu Zheng meant to ask how many Han soldiers there were. Ren Ping had already asked this sentence. The Qiang soldier replied after a while: "No, they are all Qiang and Di people."

Liu Zheng asked a few more questions, and the Qiang soldiers answered hesitantly. Liu Zheng was anxious and stopped asking him. He turned to Ren Ping and said, "Since you have asked, please tell me the situation in Gukou."

Ren Ping walked to a large stone, put down a few stones, and said to Liu Zheng: "This is the entrance of the valley. Currently, there are about one thousand soldiers at the entrance of the valley, divided into two garrison sites."

Ren Ping used two small stones to place them on both sides of the big stone, "These are two garrison sites, exactly the same as on the map, one south and one north, fifteen miles apart, and five soldiers were stationed each. They used Xinying to contact Hexi."

"Where is Xinying?" Liu Zheng asked in a deep voice, which was his most concerned issue.

"The patrol said that the Eagle Nu lived in Yingpan on the north side."

Liu Zheng pondered for a moment and said, "We must divide the troops. I will lead half of my brothers to Beiyingpan. You are responsible for seizing Nanyingpan. At the same time, you must be quick and ruthless, killing them all."

Ren Ping nodded and asked again: "When will you do it?"

Liu Zheng looked at the moonlight and said, "It's probably the first update now. I led my army to climb from the back mountain. It didn't take much time. We started to do it at the same time."

Ren Ping smiled and said, "It's time for most people to get up at night. It's better to do it in the fourth update. I think it's more certain."

Liu Zheng understood what Ren Ping meant, but in fact he gave himself a little more time. After all, the cliff was very difficult to walk fifteen miles. He thought about it and then agreed happily, "Then let's do it in the fourth update."

The two immediately divided their troops. Liu Zheng led his men to run to the outside of the valley entrance, while Ren Ping led the two to touch the valley entrance quietly.

Dadouba Valley is a southeast broken valley that stretches thousands of miles across the Qilian Mountains, forming a shortcut from Hexi to Hehuang, Longxi. It is a thousand five meters above sea level. The peaks are covered with snow all year round. The broken valley is about a mile long, and it is as narrow as the north and the south. The south is the most narrow and steep. The valley is only more than ten feet wide and is dangerous and deep. The strange peaks on both sides of the canyon stand, the cliffs are abrupt, and the strange rocks are soaring that one man can pass by, and ten thousand man can’t open it.

Dadoubagu was under the jurisdiction of the Hexi Army. One thousand Han troops were deployed here at the earliest. However, just last summer, when the fierce battle in Hefei was in full swing, Hexi implemented a major garrison adjustment. Ten thousand Han troops were transferred to Dunhuang County in the north and Wuwei County in the south, while Zhangye, Jiuquan and Juyan County were stationed by 20,000 Qiang Di troops.

The garrison of Dadou Bagu was also among the replacement of defense. The original 1,000 Han troops were transferred to 1,000 Qiang soldiers. The Qiang soldiers and Di soldiers were also Han troops, but they only followed Ma Chao's orders and ignored Chang'an military orders.

This was also a hidden danger left by that time. When the Han army attacked Longxi and Hehuang, they completely defeated the Qiang and Di people, and then mixed them with the Han people and turned them into farming. They also moved some tribes that were determined to change to farming to Qinghai Plateau, causing the original Qiang and Di tribes to shrink and die in the next few years.

Liu Jing was worried that the change would cause a large number of changes to the Qiang people in Lingzhou and the Xiongnu people in Guannei, so he retained the original tribe and did not carry out agricultural transformation like Longxi and Hehuang, which made the Qiang people and Di people in Hexi just surrender to the Han Dynasty on the surface.

After the Qiang soldiers participated in the attack on the Huns, especially the Huns in Juyanhai were wiped out. The distribution of interests involved caused strong dissatisfaction among the Qiang and Di people in Hexi. Several major tribe chiefs began to discuss independence and reached an agreement with Ma Chao who was trying to restore Xiliang.

The thousand Qiang soldiers deployed in Dadouba Valley were Ma Chao's direct army, and they used Xinying to contact Zhangye City. However, at this time, since Ma Chao had not yet publicly raised his troops to stand up, the defense in Dadouba Valley was not particularly strict and did not enter a wartime state. It was just like usual, with regular shifts of guards and sentries. There were not many sentries and military disciplines were not strict enough. For example, a missing sentry did not arouse enough vigilance from the defenders.

Ren Ping led two soldiers to run away, pulled out two posts one after another, and gradually approached the garrison barracks.

The military camp to the south is located in a valley pass. There are dozens of camp tents at the foot of the mountain. There is a military fort at the foot of the mountain. If there is any movement at the foot of the mountain, the military fort will be discovered immediately. Then, a beacon fire is raised to notify the military camp in the north, and then the military camp to the north will release a letter to inform Zhangye City.

The Eagle Strike Army ambushed a few steps away from the valley pass, waiting for the agreed time to come, Ren Ping observed the surrounding terrain. The terrain here was basically the same as the sand table they saw before they set off, but some details were not displayed on the sand table.

For example, there is a thick wooden fence at the entrance of the valley, and several soldiers patrolled back and forth in the fence. This is mainly to prevent the invasion of beasts. There are many wild wolves, leopards and other beasts in the valley, which threatens the safety of merchants and travelers. It is also a huge threat to the garrison soldiers. Just like when they found a missing sentry, their first reaction was that they were attacked by beasts. This is common in the valley, and they don’t take it seriously.

Ren Ping observed for a moment and had an idea in his mind. He summoned several generals and whispered a few orders, then led fifty people to detour from the side towards the military fort halfway up the mountain.

Time passed little by little, and the valley remained silent. It was almost the fourth hour, and it was the time when people slept the deepest at night. Everything in the valley was silent, and the owls that were moving at night disappeared.

Ren Ping led his fifty subordinates to the cliff behind the barracks, only more than ten feet away from the fort on the mountainside. Ren Ping stared at a black shadow on the top of the fort, a soldier hiding in the corner and sleeping with a military blanket. The top of the fort was Fengsui, and soldiers must stand guard here.

But now it is not in wartime, but it is just a normal watchman. The soldiers are not alert. The soldiers standing guard naturally can't stand the sleepiness and hide in the corner and fall asleep.

Ren Ping waved his hand and everyone calmed down. He slowly raised his crossbow and aimed it at the black shadow more than ten feet. This crossbow is exclusively for scouts. It is less than half of the size of a normal military crossbow. It is very light and can be fired with one hand. It has a range of killing only ten steps. The crossbow arrow is four inches long, and the tip of the arrow is highly toxic. It is the best weapon to ambush the secret whistle.

With a light click, the short crossbow arrow shot out like lightning, and it was sleeping in the middle of the soldier's neck. The soldier groaned and twitched twice, and died immediately.

At this time, Ren Ping waved his hand again, threw more than a dozen ropes down, and fifty soldiers climbed down in groups, jumping to the top of the military fort like monkeys.

They took out the bamboo tube and blew a lot of smoke into the top floor of the military fort. After a moment, more than a dozen soldiers kicked open the window and crawled in, and soon killed the guards on the top floor. They did the same thing and soon killed all the soldiers in the top floor, including a military marquis and several village chiefs.

At this moment, a fire suddenly appeared in the distance, and a faint shouting of killing came. At that time, fierce fighting broke out in the military camp in the north. Ren Ping made a quick decision and a rocket shot out. This was a signal of attack. One hundred and fifty soldiers ambushed at the foot of the mountain jumped out and ran towards the fence of the valley.

In order to prevent wild wolves and beasts from invading, the Qiang people chose a valley to camp and built a thick wooden fence at the entrance of the valley. This way, they could indeed effectively defend against night attacks of beasts.

But everything has its pros and cons, but this kind of camping makes it easy for the enemy to be blocked in the valley. Ren Ping took advantage of this weakness of the enemy's camp and sneaked into the military fort on the mountainside, giving the Han army a condescending advantage.

Fifty soldiers were carrying tincture oil bags. They took off the bags and sprayed the tincture oil into the camp at the foot of the mountain. Several torches were thrown down the valley, and a raging fire suddenly ignited in the valley military camp.
