The Qilian Mountains are one of the most important mountain ranges in China. It consists of multiple northwest-southeast trending parallel mountains and wide valleys. It is 800 kilometers long from east to west, 200-400 kilometers wide from north to south, and 4000-6000 meters above sea level. There are 3,306 glaciers with a total area of about 2,062 square kilometers.

The whole mountain range is like a natural barrier, blocking a large area of land west of Jincheng County and now belonging to the Western Regions Protectorate (that is, Qinghai Province now) from Liangzhou, so that only the westernmost Yangguan and Yumen Pass can be passed, and this road is the famous Hexi Corridor, which is the most important section of the Silk Road in later generations.

On the night when Cheng Yinggong reported to Han Sui, a caravan of about 100 people quietly arrived outside Yangguan in the southwest of Liangzhou. By this time it was already dark, and the gate had long since been closed. The caravan did not force the customs clearance, but chose to camp near the mountains and forests outside the customs, preparing to enter the customs again early tomorrow morning. In this regard, the officers and men on the wall have long been accustomed to it and have not paid much attention to it.

After a while, a bonfire was lit outside the gate, and the smell of meat made people's appetite move, and a soldier defending the city couldn't help but swallow his saliva, and subconsciously looked outside the gate, and suddenly his eyes were round, and he couldn't take his eyes off again! At this moment, there were several women of different races singing and dancing beside the fire, and the revealing clothes made the soldier's saliva water.

Seeing this, several soldiers on the side also followed his gaze, and one of them, who seemed to be the captain, couldn't help but kick the people around him.

"What do you see? It's not the first time I've seen Hu Ji, this group of people is a big businessman in the Western Regions Protectorate at a glance, maybe they still know us Lord Han, don't make a bad idea! ”

"No... No... Captain, look... Look over there! ”

Everyone looked in the direction of the soldier's finger, and they couldn't help but be stunned, and their faces were greedy!

Maybe it was the tarpaulin on the carriage that was blown by the wind, but through the light from the bonfire, you could see the crystal clear light inside, and if you looked closely, it was actually a box of agate jade!

This kind of agate can be exchanged for a small house in a small place, and now it is full of cars... Several people couldn't help but swallow their saliva in unison, and when they looked at each other, they all saw greed in each other's eyes...

"Boss, why don't we call the Captain to do his vote?" A soldier stared straight at Orchid's chest, which was shaking with the swing, and said with difficulty.

"Look at your worthless look!" The captain pursed his lips and continued: "There are less than a hundred of them, and later while they are asleep, we will secretly go out and give them to..."

"What the boss said is that when the time comes, we will take these jewels to Chengdu or Zhongyuan to buy a family business, and then take a few concubines, and we will be able to have no worries about food and clothing for the rest of our lives!"

About half an hour later, the merchants outside the city were full of wine and food, and they all hugged the orchid into the tent to rest. Soon, silence regained on the mottled ancient road.

After a while, there was a squeaky sound in the silent night, and more than forty black shadows slowly came out of the crack in the door, the first of which was the captain who had been on the city wall before.

A group of people tiptoed to more than ten tents, gestured to the people around, the soldiers dispersed, the captain came to the largest tent, smiling and raising the curtain, at this moment, the dense forest behind him suddenly sounded a rapid sound of breaking wind, before the captain reacted, he felt a pain in his heart, and then the whole person lost consciousness...

At the same time, countless soldiers flashed in the mountains and forests and rushed towards the gate where the gaps were exposed, and when people were still asleep, this Xiongguan, which was famous in history and had the name of "no reason for the West Out of Yangguan", had quietly changed hands.

Coincidentally, the same scene also happened in Yumen Pass, another Xiongguan in the northwest of Liangzhou, the difference is that it is simpler there, and before the wealth is displayed, just seeing the graceful orchid, the soldiers can't help but open the door directly to snatch the orchid for fun!

The two key points of connecting the Western Regions Protectorate and Liangzhou were all owned by He Si'an overnight.

Early the next morning, in Dunhuang Taishou Li Kan was woken up by the shouting outside, and in a daze, he heard hurried footsteps outside the door, and then the bedroom door was pushed open with a bang, and the housekeeper didn't bother to knock on the door, so he rushed directly into Li Kan's room, causing the concubine in his arms to exclaim.

"Lord Taishou, it's not good, a large number of enemy troops are entering the city."

"What? How is this possible?! Didn't Lord Han already cooperate with the Huns? Could it be that they have backtracked? ”

Li Kan blurted out, his eyes full of confusion. Fortunately, there was still a mess outside at this time, and the housekeeper didn't care about what his lord said, but said anxiously: "It's not the Huns, look at the clothes, it should be the soldiers and horses under King Hongnong!" ”

Hearing this, Li Kan calmed down, what should come will come after all, since he chose to be with the Huns, then he has to face the consequences.

Dressed neatly, Li Kan picked up the big knife in his hand and rushed out of the Taishou Mansion, at this moment there was already a mess outside, fortunately, the Huns left some people to help defend the city, plus their own men desperately blocked, although they were caught off guard at first, but with the bravery of the Huns and the desperate resistance of his soldiers, they were not directly defeated, but after all, the opportunity has been lost, and the defeat is only a matter of time.

Seeing Li Kan come out, his guards hurriedly stepped forward.

"The enemy army has broken the city, let's buy time for the adults, the adults better flee quickly!"

Hearing this, Li Kan was furious.

"Let's go! How can I leave you behind! ”

"My lord, there's no time!"

When several people were entangled, the leading Dong Yue led the troops to kill here, and at a glance he saw Li Kan in front of the Taishou Mansion, Dong Yue snorted coldly and rushed directly to kill!

Li Kan and others on the opposite side also found Dong Yue's arrival, and the guards hurriedly drew their waist knives to block the front, but in a hurry, which was Dong Yue's opponent, they saw the iron spear flying up and down, and all the guards who were blocking the way were knocked down in a few stabs.

Hearing only a loud sound of the bell, Li Kan stepped back a few steps, and the war horse under Dong Yue seemed to be unable to withstand the force, and as soon as the horse's legs bent, Dong Yue's whole person fell directly to the ground.

Li Kan, as one of the eight horsemen under Han Sui, his strength and experience should not be underestimated, and when he saw that the opponent's horse stumbled, he was immediately overjoyed, and did not hesitate to step forward and raise his knife to slash.

Dong Yue just got up, he saw a big knife cut head-on, and hurriedly raised the gun to block, with a loud noise, Dong Yue only felt that his arm was numb, and his eyes flashed, taking advantage of the moment when Li Kan's big knife was knocked away, he held the handle of the gun tightly, and made a fierce round with one hand, only to hear a click, and the iron gun was directly pumped on Li Kan's waist impartially...
