Two hours later, two Tibetan ships appeared on the sea, these were two medium-sized grain ships, they did not come to the island, but slowly passed five miles west of the island, at this time, all the Tang troops on the island entered the castle that had not yet been repaired, and hundreds of Tang troops stood on a section of the city wall that had been completed, with bows and arrows, waiting for the battle.

Li Qing'an held the curtain and looked at the Tibetan ship in the distance, the carelessness of the Tibetan ship did not seem to be hostile, and the two ships could not carry many soldiers.

Bai Yuanguang looked at it for a long time and said, "Qilang, these two ships don't seem to be coming for our island. ”

"Not necessarily!"

Li Qingan shook his head and said, "Neither to transport troops nor food, these two ships are most likely here to reconnoiter our island." ”

Sure enough, as Li Qing'an expected, after the two ships reached the northwest direction for five miles, they turned around and came eastward, and the speed of the ships increased, obviously circling the island.

"Fuck, go kill them!" Li Fei Yuanli scolded resentfully.

"Can't catch up with them."

Lifei Shouyu sighed softly and said, "It seems that our existence has made the Tubo army restless. ”

Li Qing'an stared for another moment, and he suddenly ordered: "He Yingchuan! ”

"The last general!"

He Yingchuan stepped out and bowed.

"Take two hundred Jiangduying brothers and take five boats to intercept them, and scuttle these two ships for me."

"Obey!"

He Yingchuan waved his hand and rushed down the mountain with several teams of Jiangdu Battalion soldiers.

．．．．．．

These two Tibetan ships came from the south coast of Qinghai, and there were not many troops on board, less than 100 people, but there was a senior general of the Tubo army on board, that is, the former commander of the Tubo army, the governor of the Tubo State and the governor of Dafei Sichuan.

Dazaru Gong Han name Ma Chongying, is one of the four ministers of Tubo, is also a famous general of Tubo, acting ruthlessly, very strategic, to the first year of Germany, it is he led the Tubo army into Chang'an, wantonly slaughter and loot, brought a deep disaster to the Tang Dynasty.

This time Ma Chongying was appointed as the commander of the former army, commanding 150,000 troops to confront the Tang army, he made careful deployments, 30,000 heavy troops were deployed on the first line of Datong Mountain in the north, 20,000 Tubo troops were deployed in Chiling, and Dafeichuan was stationed with 100,000 troops, blocking all the roads of the Tang army to the west, despite this, Ma Chongying still made a small strategic mistake, he only stationed 3,000 troops in Haixi Fuqicheng, he did not take into account that the Tang army would attack from the western front, in fact, he took into account, but he thought that the western front could not establish a supply line, It was impossible for the brigade of the Don Army to come from the Western Front.

However, the city was attacked by a Tang army, hundreds of thousands of military rations were burned, the general Shang Xi Dongzan was killed, and the Tubo army was forced to withdraw 40,000 troops back to Wuhai, so that the front army of the Tubo army fell to 110,000, and one of his negligences caused serious consequences.

The Great Minister Shang Jiexi took the opportunity to impeach him to Zampu and removed him from the post of Great Comment, but Zampu Trisong Dezan was unwilling to temporarily change the general, and still ordered him to command the Battle of Tangbo.

Ma Chongying learned a lesson, adjusted the deployment of troops, transferred 10,000 troops from Datong Valley to garrison Fuqicheng, and strengthened patrols along the coast of Qinghai.

Based on the experience of Fu Qi City, he personally took a boat to inspect the sea, and the situation made him worried, and the Tang army actually built a castle on Longju Island.

Ma Chongying looked at the towering castle on the top of the hill from afar, his mood was particularly heavy, judging from the scale of this castle, at least two thousand people could be stationed, although two thousand people were not much, but it was like a sharp knife, against the back of Chiling, seriously threatening the supply line of the Chiling Tubo army.

At this time, the general beside him said in a low voice: "Dudu, it is now winter, and in half a month, the sea will be frozen, and it will not be too late for us to bring in a large army to attack at that time." ”

Ma Chongying didn't speak, he pondered for a moment and said, "When we came over in the morning, we seemed to see smoke rising from the three reef islands, it should be their beacon fire!" ”

"It must be! Otherwise, let's kill the beacon first. ”

"Nope! It was useful to keep it. ”

Ma Chongying smiled faintly and said: "If I guess correctly, the Tang Army should also have a beacon tower on the side of Sand Island, so that the reason why there is a Tang Army beacon tower on the coastal mountain on the side of North Chiling can be explained. ”

"What does the governor mean by not fighting Longju Island for the time being?"

"Did I say I wouldn't fight?" Ma Chongying snorted, "The Tang Army's garrison on Longju Island makes it difficult for me to sleep and eat, if I don't fight, I will not get rid of my heart disease, and I will cry and hide, and when the sea water freezes, you will attack Longju Island and implement my strategy." ”

As soon as Ma Chongying's words fell, someone on the boat suddenly shouted: "Governor, there is a boat from the Tang Army coming out behind." ”

Ma Chongying was taken aback, he hurriedly turned his head to look at the island, and sure enough, he saw several big ships sailing out of a bay, these big ships were actually their lost grain ships, Ma Chongying looked up, could it be that the garrison on this island was the Tang army that attacked and broke the ambush city, and made him be punished by Zampu?

It must be so! Ma Chongying gritted his teeth for a while, and he immediately ordered: "Speed up and get rid of the ships of the Tang Army." ”

All the sails on the Tibetan ship were pulled up, and with the help of the strong west wind, they sailed away like arrows to the east.

On the castle, Li Qing'an looked at the whereabouts of the two Tubo ships from a distance, the two ships were extremely fast, and it was difficult for the Tang army to catch up, he looked up at the sky, a trace of worry flashed in his eyes, and he turned around and said, "Please come over two monks." ”

After a while, two old monks hurriedly came, although Li Qing'an demolished their temple, but also promised to rebuild a larger temple for them after the end of the Tangbo Campaign, or let them go to the Central Plains Temple to preside, especially the latter one made the two monks overjoyed, no matter how big the temple on Longju Island was built, what was the use of no pilgrims?

The two old monks walked up to Li Qing'an, clasped their palms together and saluted, "What is the general looking for us?" ”

"Let me ask you, when is the ice period in Qinghai?"

"Back to the general, the ice period in Qinghai is very punctual, starting at the end of October every year, first by the sea and then slowly extending to the center of the sea, at most half a month, the entire sea surface is covered by thick ice."

"Is it possible to march on the ice?"

"It's completely possible, the ice is half a foot thick, and it is feasible for people and horses, three years ago, I saw with my own eyes a 20,000-strong Tibetan army marching from the south shore to the north shore, carrying a large amount of grain and grass, and passing by our island, the momentum was extremely huge."

Li Qing'an nodded, and said to Luo Han again: "The city wall is thicker by one foot." ”

"The last general obeys!"

At this moment, the Tang army shouted, only to see a Tubo ship on the sea turned around to meet it, there were nearly 100 Tubo troops on the boat, arrows like rain, shooting towards the main ship of the Tang army, and the other Tubo ship went faster and faster, did not turn its head to the south, and galloped directly to the east, the three boats of the other Tang army saw that there was no hope of catching up, they surrounded the Tubo boat that turned around, and attacked with arrows on all sides, more than a dozen Tang troops with excellent water surnames have been launched, the two armies are arrows on the sea, shouting like thunder, and people continue to fall into the sea with arrows, Four big ships of the Tang army surrounded the Tubo ship in the middle, and at this moment, there was a shout on the Tubo ship, and the Tubo ship began to tilt and sink, and the Tubo army on the ship was in chaos, and in just a moment, the Tubo ship disappeared into the vast sea.

Dozens of Tubo soldiers who fell into the water were captured or killed, Li Qingan stared at the Tubo boat that ran away, and shook his head with some regret, there was a ship that did not want to protect it, and there may be high-ranking Tubo officials on that ship, but it's a pity! Let it run.

．．．．．．．．

The weather was as cold as a day, and after another heavy snowfall on October 23, Qinghai entered the ice age, and Longju Island was also covered with ice and snow, but the upsurge of Tang military warfare was high, Yinglongcheng had been completed ahead of schedule, and most of the war horses were all sent back to Shanzhou, so that the Tang army had no worries.

On the 10th day of November, Qinghai has been completely frozen, the vast and clear sea surface is frozen and jade, covered in silver, just like a huge treasure mirror, shining in the sun, and finally radiating dazzling brilliance, several Tang soldiers have done an ice chiseling experiment, the sea surface is frozen up to five feet thick, not only is it feasible for men and horses, but also can be transported with large baggage sleds, and the time is ripe for the Tubo army to attack the island.

At noon on this day, Li Qing'an, as usual, inspected the Tang army's combat readiness in the castle, the southwest corner of the castle is the weapons workshop, nearly a hundred Tang army blacksmiths are busy improving the Tang army's armor arrows, and making trebuchets, the castle defense is condescending, and the long-range trebuchet has the best effect.

"General, this is the latest trebuchet, there is a special winch, only twenty people can throw fifty pounds of boulders to eight hundred steps away, and the joints are made of iron shafts, which is more durable."

A Tang general introduced the trebuchet to Li Qing'an, who nodded and asked, "How many planes can be made per day now?" ”

"General Hui, five planes are made every day, and we have made nearly a hundred."

"General!"

Captain Rohan hurried in with a soldier, and he pointed to the soldier and said, "This soldier has a good way to defend." ”

"What's the best way?"

The soldier stepped forward and saluted: "General, when we were polishing the bluestone today, we found that there was a thick layer of ice on the bluestone, and the chisel was slippery, so there was no way to use force, and my subordinates thought, if our city wall is also thickened with a thick layer of ice......

Before he finished speaking, Li Qingan smiled and said, "Then the Tubo army will not be able to climb the city, right!" ”

"That's right! Not only can the city not be climbed, even if the Tibetan army attacks the city with trebuchets, the stones will slip, and they can be repaired at any time. ”

A blacksmith next to him smiled and said: "General, then when we use ice water to water the city, we can make a downward inclination, and the trebuchet generally does not hit in a straight line, but smashes from top to bottom, just to remove the force of the stone to hit the city wall." ”

"General, I also have a suggestion that the mountain road can also be poured into ice to make it impossible to climb up the Tubo Mountain."

Everyone said a word, and soon put forward more than 20 opinions with a very strong construction surname, Li Qingxin was overjoyed, and said to everyone: "I will reward those who make good suggestions." ”

He turned back and ordered, "Pass the order and pour the ice city immediately!" ”

．．．．．．．．

Two days later, the rapid bell rang throughout the island, and 2,000 Tang troops rushed to the city, only to see the smoke rising from the three reef islands in the south, and the beacon tower of the nameless reef in the east also had three pillars of black smoke rising, which indicated that more than 10,000 Tubo troops were killing from the east and south, and cut off the retreat of the Tang army.

The city was immediately busy, and the Tang army was methodically carrying stones, adjusting trebuchets, preparing arrows, and setting up pots to boil water.

But Li Qing'an was still staring at the wolf smoke in the distance, and their brows were furrowed.

"Shichiro, what did you find?" Li Fei Shouyu stepped forward and asked.

"Don't you think it's strange? Why does the beacon smoke keep going? ”

Li Qingan turned around and asked him: "Shouyu, if you were the commander of Tubo, would you let the beacon tower ignite?" ”

Li Fei Shouyu's face became solemn, and he shook his head and said, "Never!" I would choose a snowy night and attack the beacon at night to blind us, and then the army would suddenly attack and catch us off guard. ”

"You're right, if I'm not mistaken, the beacon tower has been captured by the Tubo army."

"But why do they light beacons to confuse us?" Li Fei Shouyu asked puzzled.

"It's not just as simple as confusing us."

Li Qing'an slowly narrowed his eyes and said slowly: "I thought of a conspiracy of the Tubo people. ”

He suddenly turned around and ordered, "Where is Nan Jiyun?" ”

．．．．．．．．．

When Nan Jiyun led 300 cavalry to leave Longju Island for an hour, a long black line appeared on the east and south sides of Longju Island at the same time, and nearly 20,000 Tubo troops slaughtered in a mighty manner.

The Tibetan army marched not fast, they used heavy sleds to carry a large amount of grain and grass baggage, heavy sleds are made of pig iron, two rails about three zhang long, welded with iron bars in the middle, a sleigh can transport thousands of pounds of materials, each sleigh is pulled by three horses.

Among these military supplies, tents, food, meat, arrows, weapons, heavy trebuchets, ladders, etc., all the materials for attacking the island castle were all available.

The Tibetan army was getting closer and closer, and they turned from a black line to an overwhelming black carpet, and the ranks were neat, and the heavy sleds like small mountains were interspersed in them.

The Tibetan army stopped on the ice two miles from the island, they did not rush to attack, but began to set up tents, and after half an hour, thousands of gray mushrooms appeared on the ice, surrounding the island, and the five mountains of grain and grass were covered by a huge curtain, which was enough for 20,000 Tibetan troops to eat until next spring.

Obviously, the Tibetan army is ready to fight a protracted war, and the strange thing is that the beacon fire in the south has been extinguished, but the beacon tower in the east is still three pillars of black smoke in the sky, and there is a tendency to burn more and more.
