As soon as the next day dawned, the king of Jialan, Guole, got the news that a Tang army of more than 100 people appeared in the canyon west of Jialan City, Guole was still very nervous, he was worried that his secret collusion with the Tubo people had been known by the Tang army, so he immediately sent people to ask the Tubo army for help.

The Tubo army has a garrison of 800 people at the entrance of Chifotang Road, led by a thousand-commander, their garrison is about 20 miles away from the palace, although Guole sent a letter saying that only more than 100 Tang troops were found, but the Tubo army became vigilant, the Tang army appeared Datler Manchuan, it is by no means a good thing, the leader of the Tubo army immediately decided to go to reinforce Jialan City, and at the same time moved the garrison of the Tubo army to a more dangerous vicinity of the palace, as long as it held there, even if the Tang army came tens of thousands, they were not afraid of them.

Eight hundred Tibetan troops abandoned their garrisons and marched along the river valley to Jialan City, while at the same time, a Tibetan squad entered the secret road and headed east, and they were going to Lianyunbao to report the movements of the Tang army.

The heat shrouded the river valley, it was hot and sultry, it was less than ten miles, the weather in the valley was changing, the morning was still sunny and shining, but at noon it was dark clouds like ink, shrouded in the valley, the canyon was dark, suddenly lightning and thunder, the torrential rain was like a note, the Tubo army was caught off guard, they led their horses to the high place, the Tubo army has experience, if the rainstorm is a little longer, it is likely to cause a flash flood, swallow them all.

They soon found a mountain cliff crevice, everyone hid in it, this cliff crack as if the mountain was split by a sword, forming a huge palace, can accommodate tens of thousands of people, although the Tubo army has more than 800 people, but they only occupy a small corner of the palace, the other corner is tied to their war horses, at this time, the underground palace is full of noise, several bonfires are burning, the Tubo people gather around the bonfire to bake clothes, talk loudly, drink barley wine, and their leader is called Lunduojie, he seems a little impatient, From time to time, he jumped onto a big rock to check the situation of the rainstorm outside, he was anxious, if Jialan City was seized by the Tang army, his surname would be difficult to protect.

On Duojie sat down and drank a few sips of barley wine, and couldn't help but climb up the big rock to check the situation outside, the rainstorm had been falling for a long time, but it didn't stop at all.

At this moment, on Duojie suddenly saw a little metal light, as if the starlight in the dark sky flashed, in the blink of an eye this bright light came to the eyes, on Duojie saw clearly, it was actually a streamlined arrow, coming rapidly, the light of a star on the arrow was like a grim smile of death, on Duojie only felt a sharp pain in his forehead, and his eyes were dark.

With a scream, he fell from the boulder, and a wolf's tooth arrow pierced his head, and under the reflection of the bonfire, he could clearly see that two words were engraved on the arrow's body, 'Ling Shan', and the other two words 'blood arrow' were submerged into his head.

The sudden change made the dungeon silent, the Tubo soldiers looked at the corpse of the leader blankly, suddenly, they jumped up, but it was a little late, suddenly rushed into a large group of Tang troops from the rainstorm, they held bows and arrows in their hands, and the arrows were like rain for a while, the Tubo army was shot into a large area in a moment, wailing all over the ground, several Tubo soldiers fell into the fire with arrows, the fire instantly burned all over the body, they struggled to get up, cried and ran a few steps, and fell down again heavily, curled up into a ball.

The Tang army roared in, the long lance was sharp, the horizontal sword was cold, and the unsuspecting Tubo army was killed to the point of flesh and blood, the heads rolled to the ground, crying, shouting, and screaming, and the underground palace suddenly became a hellish slaughterhouse.

Li Qing'an rode around and galloped in the underground palace, drew his bow like a full moon, and killed more than 30 Tibetan soldiers in a moment.

At this time, a tall Tubo centurion as tall as a bear is fierce and abnormal, he is wearing chain mail, not afraid of swords, and five Tang soldiers in a fierce battle, he is berserk and abnormal, killing three Tang soldiers in a row, suddenly he was stabbed on the back, the sharp horizontal knife cut off the chain mail, and suddenly the blood flowed, the Tubo centurion suddenly turned around and grabbed the Tang army, a wild roar, actually tore the Tang army in half, bloody, miserable, Tubo centurion raised his head and laughed.

Li Qing'an was furious, he pulled out an iron arrow, his eyes narrowed slightly, staring at the bloody mouth of the wild laugh, and gradually pulled the bow to the full, as soon as the string was loosened, the iron arrow shot out like lightning, the fierce Tubo centurion was shot into the mouth by an arrow, the iron arrow came out of the brain, the blood plasma sprayed, and the arrow power was extremely strong, nailing him to the ground alive.

As the Tibetan centurion was shot to death by Li Qing'an, the morale of the Tibetan people was completely wiped out, and the Tang army was killed to the point of blood, and more than 800 Tibetan soldiers were finally killed, and none of them survived.

The battle gradually ended, the huge underground palace was full of corpses, filled with a pungent smell of blood, and the sticky blood water merged into a stream, flowing into the depression in the middle, and soon gathered into a blood pond, dozens of Tang soldiers who died in battle were cremated on the spot, and the bones were packed into urns and brought back to their hometowns in the future.

The figure swayed in the rain and fog, and Lifei Shouyu returned with dozens of soldiers.

"How's it going, have any of them slipped through the net?"

"General Hui, we ambushed the Tubo squad upstream, and all ten Tubo messengers were killed, none of them escaped the net, and the Tubo garrison was empty."

"Well done!"

Li Qing'an looked at the hellish dungeon, frowned, and then ordered: "Cut off their heads and take them away, and burn their corpses." ”

When the stench of corpse smoke filled the underground palace, the Tang army had already left, and disappeared into the vast rain with the horses of the Tibetans.

．．．．．．．

The rain had gradually stopped, and the torrent had not broken out, but the water of the Datler River had swelled, and the sound was like thunder in the narrow places.

The Tang army gradually approached the palace of Jialan City, the palace was like a great enemy, King Guole almost mobilized the entire city's army to guard the palace, in fact, there were only more than 1,000 people, they stood densely on the platforms on both sides of the palace, looking at the Tang army from the east with anxiety.

"General, do you want to attack?" Li Fei Shouyu asked in a low voice.

"No, you don't! To deal with such weak soldiers, we do not need casualties in the Don Army. ”

Li Qingan turned around and ordered: "Build a head mountain." ”

A hundred steps away from the palace, the Tang army began to build a mountain of human heads with Tibetan heads, more than 800 human heads all with hideous faces, some still wearing helmets, some with scattered heads, some with angry eyes, some with painful expressions, and even some burned beyond recognition.

The mountain of human heads was quickly erected, forming a shocking bloody picture, which was particularly terrifying, and many soldiers in the palace began to vomit, most of them trembled with fear, and the king of Garan, Golle, turned even pale, and the queen beside him suddenly saw what the hill was made of, and she screamed in fright, and fell to the ground softly, and passed out.

Li Qing'an inserted a letter on the shaft of the arrow, his giant bow gradually pulled away, aiming at the golden crown of the King of Jialan a hundred steps away, the string was loose, and the long arrow shot a parabola, flying towards the King of Jialan on the platform, a shout on the platform, Guole was at a loss, when he saw that the arrow was actually shooting towards him, he was so frightened that he was too late to hide, 'Bang! With a thud, the arrow entered his golden crown, and his scalp even felt the cold shaft of the arrow, and Goller's eyes were dark, and he fainted with fright.

"King! Queen! ”

There was a lot of chaos on the platform, and in the middle of the night, Gole woke up, and he shouted: "I'm going to die!" I'm going to die! ”

"My Majesty, it's a letter."

"Letter?"

Gole was so weak that he couldn't even hold the letter, and he said in a trembling voice, "What is written on it?" ”

The guards tore open the letter, which was written in Tocharian with only one sentence: 'Surrender to the Tang Dynasty, continue to be the king of Garan, do not surrender, and build another mountain of human heads.' ’

"King, what should I do?"

Gole sighed, "What else can I do, tie me up with the queen and surrender!" ”
