As soon as the next day, Jialan King Guole received news. A group of more than a hundred Tang troops appeared in the canyon west of Jialan City. Guole was still very nervous. He was worried that the Tang army had already learned about his secret collusion with the Tubo people, so he immediately sent someone to ask for help from the Tubo army.

The Tubo army had 800 troops garrisons at the entrance of Chifotang Road, led by a thousand-man commander. Their garrison was about twenty miles away from the palace. Although Guole wrote that he had only found more than a hundred Tang troops, the Tubo army became alert. It was definitely not a good thing for the Tang army to appear in Datler Manchuan. The leader of the Tubo army immediately decided to go to reinforce Jialan City, and at the same time moved the Tubo army's garrison to the more dangerous palace. As long as he guarded it, even if the Tang army came to tens of thousands of people, he would not be afraid of them.

The eight hundred Tubo troops gave up their garrison and headed towards Jialan City along the river valley. At the same time, a Tubo team entered the guardrail passage and headed eastward. They were going to Lianyunbao to report the movements of the Tang army.

The heat covers the river valley, which is sultry and hot. After walking less than ten miles, the weather in the river valley changes as soon as possible. The sun is still shining brightly in the morning, but at noon, the clouds are as dark as ink, covering the valley. The valley becomes dark. In an instant, lightning and thunder are roaring and heavy rains are pouring. The Tubo army is caught off guard, and they lead their horses to the high places. The Tubo army has experience. If the heavy rain falls longer, it is likely to cause mountain torrents and swallow them all.

They quickly found a cliff in the mountain, and everyone hid in it. The cliff seemed to be split by a sword, forming a huge palace that could accommodate tens of thousands of people. Although the Tubo army had more than 800 people, they only occupied a small corner of the palace, with their war horses tied to the other corner. At this time, the underground palace was filled with noise, and several bonfires were burning. Tubo people gathered by the bonfire to bake clothes, talking loudly, drinking barley wine, and their leader was called Lun Duojie. He seemed a little impatient and restless. From time to time, he jumped to a big rock to observe the heavy rain outside. He was anxious. If Jialan City was seized by the Tang army, his life would be difficult to protect.

Lun Duojie sat down and drank a few sips of barley wine, but couldn't help but climbed up to the big stone to observe the situation outside. The heavy rain had been falling for a long time, but it didn't stop at all.

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

Lun Duojie screamed and planted from the big rock. A wolf-toothed arrow shot through his head. Under the reflection of the bonfire, you can clearly see the two words "Lingshan" engraved on the arrow, and the other two words "Blood Arrow" penetrated into his head.

The sudden change made the underground palace silent. The Tubo soldiers stared at the leader's body blankly. Suddenly, they jumped up one after another, but it was a little late. Suddenly, they rushed into a large group of Tang soldiers from the heavy rain. They held bows and arrows in their hands. The arrows were like rain. The Tubo soldiers were shot into a large area in a moment, and wailed everywhere. Several Tubo soldiers were caught in arrows and fell into the fire. The fire burned all over their bodies in an instant. They struggled to get up, cried and ran for a few steps, and fell heavily again, curled up.

The Tang army roared in, with a sharp spear and a cold sword. They killed the Tubo army without any defense and flesh and blood, and their heads rolled on the ground, crying, shouting, and screaming. The underground palace suddenly turned into a hell slaughterhouse.

Li Qing'an rode his horse around in the underground palace, pulling his bow like a full moon, and taking his arrows to death. In a moment, he shot more than 30 Tubo soldiers to death.

At this time, a Tubo centurion, who was as tall as a bear, was extremely fierce. He was wearing chain mail, not afraid of swords, and fought with five Tang soldiers. He was extremely violent and killed three Tang soldiers in a row. Suddenly, he was stabbed on his back. The sharp horizontal sword cut off the chain mail, and blood was flowing. The Tubo centurion suddenly turned around and grabbed the Tang army. With a roar, he actually tore the Tang army in half. It was bloody and terrible. The Tubo centurion raised his head and laughed.

Li Qing'an was furious. He pulled out an iron arrow, narrowed his eyes, stared at the big, laughing bloody mouth, and gradually pulled the bow to fullness. When the string was loosened, the iron arrow shot out like lightning. The fierce Tubo centurion was shot in from his mouth with an arrow. The iron arrow penetrated his brain, and the plasma splattered. The arrow power was extremely strong, and he was nailed to the ground alive.

As the Tubo centurion was shot to death by Li Qing'an, the morale of Tubo disappeared and was killed by the Tang army and blood flowed into a river. More than 800 Tubo troops were eventually killed, none of them alive.

The battle gradually ended. The huge underground palace was covered with corpses, filled with pungent blood. Sticky blood flowed into a stream and flowed into the depression in the middle. It soon formed a blood pond. Dozens of Tang soldiers who died in battle were cremated on the spot, put the bones in jars, and brought them back to their hometown in the future.

The figures swayed in the rain and fog, and Li Fei Shouyu came back with dozens of soldiers.

"How about it, are there any fish that misses the net?"

"Report to the general, we ambushed the Tubo team in the upper reaches. All ten Tubo newsmen were killed, none of them missed the net, and the Tubo station was empty."

"here you go!"

Li Qingan looked at the hellish palace, frowned, and then ordered: "Cut off their heads and take them away, and burn them."

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

The rain had gradually stopped and the mountain torrents did not erupt, but the water in the Datler River surged, like horses galloping in a narrow place, and the sound was like thunder.

The Tang army gradually approached the Royal Palace of Jialan City. The palace was facing a great enemy. King Guole mobilized almost all the troops in the city to guard the Royal Palace. In fact, there were only more than a thousand people. They stood densely on the platforms on both sides of the palace, looking at the Tang army coming from the east with a nervous mood.

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

"No! We don't need to deal with such weak soldiers to have casualties."

Li Qing'an turned around and said, "Build Rentou Mountain."

A hundred steps away from the palace, the Tang army began to build Rentou Mountain with Tubo heads. More than 800 heads were all ferocious, some still wearing helmets, some were disheveled, some were full of hair, some were full of eyes wide open, some had a painful expression, and some even burned heads beyond recognition.

Rentou Mountain was quickly set up, forming a shocking bloody picture, which was particularly frightening. Many soldiers in the palace began to vomit, most of them were trembling with their legs, and Jialan King Guole's face was even more pale. The queen beside him suddenly saw clearly what the hill was made of. She screamed in fear, fell softly and fainted.

Li Qingan inserted a letter on the arrow shaft. His giant bow gradually opened and aimed at the golden crown of Jialan King a hundred steps away. The long arrow shot out a parabola and flew towards Jialan King on the platform. A shout from the platform, Guole was confused. When he saw clearly that the arrow was shooting at him, he was so scared that he was so scared that he was too late to hide. With a "crack!", the arrow shot into his golden crown. His scalp even felt the cold arrow shaft. Guole's eyes turned black and he fainted.

"King! Queen!"

There was a turmoil on the platform. After a while, Guole woke up and shouted: "I'm going to die! I'm going to die!"

"Master, it's a letter."

"letter?"

Guole was so soft that he had no strength that he could not even hold the letter. He said tremblingly: "What is written on it?"

The guards tore open the letter, which was written in Tochari, with only one sentence: "Surrender to the Tang Dynasty, continue to be the King of Galan, and do not surrender, and build another Rentou Mountain."

"Master, what should I do?"

Guole sighed, "What else can I do? Bind me and the queen and surrender!"
