Li Tiantu, who had been a close minister of the Son of Heaven, of course knew that Tianxuandu's gout had been poisoned into the bone marrow and had been a stubborn disease for decades. If it had been placed ten years ago, with the theory of medical Taoism in the "Heavenly Dao True Scripture", he would have been more than eighty percent sure that he would have cured this disease. But now, even if there is no Chengcheng, how dare he treat the Son of Heaven?

Fortunately, there is still a meridian flower on his body, which was inadvertently obtained in the Heavenly Medicine Garden when he entered the Kunlun Temple at the beginning of that year, and it may be able to temporarily relieve the crisis of Tianxuandu's serious illness this time. As for how many years to live, then it can only be left to fate.

Li Tiantu gave Zhu Wenwu a letter of repair, and invited Gong Tu to take the meridian flowers and rush to Beijing on a fast horse. This time, his intention was naturally to borrow the hand of Zhu Wenwu, the head of the household department, to prolong the life of Tianxuandu.

After doing this, Li Tiantu easily went north to the Western Regions.

In the south of Xizhou City, the Tubo camp on the rocky slope.

Lingyou, who had a grim face, kept pacing in the tent of the Chinese army commander.

On the desk not far away, there is a brown paper letter, and the front of the letter is printed with the large seal of the king of the Tibetan court.

Ten days later, Ashina drove his own expedition, accompanied by His Royal Highness King Ming, and sent 20,000 royal red guards and 200,000 Tibetan iron horsemen to Xizhou City again, intending to take down the nail of the Celestial Empire in the Western Regions in the shortest possible time.

There were more than 70,000 people and horses on the rocky slope, but it was a full 300,000 people.

Ling You calculated the time, more than two months had passed since Li Tiantu left, and he secretly put it under the water, presumably Xizhou City had hoarded a lot of grain and grass.

With an army of 300,000 besieging the city, as well as His Royal Highness King Ming in the body of the Buddha and a group of masters of Daluo Palace, it seems that it doesn't matter how much grain and grass there is in Xizhou City.

He even believed that as long as the eldest brother couldn't come back, Xizhou City wouldn't be able to last even a month.

Thinking about it further, if Tubo took Xizhou City at lightning speed and relieved his worries, he took advantage of the chaos in the Celestial Dynasty when the emperor was seriously ill and waved his troops to Liangzhou, and crushed the 30,000 Liangzhou children who sealed thousands of miles as if they had played at home, as long as the Celestial Empire could not gather superior forces from various states in a short period of time, and when the Tubo troops suppressed the capital of the Celestial Empire, what kind of climate could the 80,000 Yulin army in Fengtai in the western suburbs alone?

Of course, Tianxuan was not confused, and he actually recalled the Heavenly Dynasty God of War Bei Shen Supreme to sit in the Yulin Army in Beijing when he was seriously ill.

Ling You's eyes were full of lightning, and he was very much looking forward to fighting with the first person in the Celestial Empire army, Bei Ming, and using his own 400,000 superior troops to force the 80,000 Yulin Army that occupied the geographical advantage, he was confident enough to defeat the North Ming Supreme and win the highest honor in the army.

Although Lingyou's ideals are good, the reality is not always true.

Li Tiantu saw signs of the movement of a large number of Tubo cavalry on the way to Xizhou, and knew that after a delay of more than a month, the Tubo royal court still decided to use troops again in Xizhou City.

He worked day and night non-stop, and finally arrived in Xizhou City before the Tubo army pressed the border.

After seeing Xue Rang in the Metropolitan Protectorate in the center of the city, Li Tiantu told everything he knew.

"There is plenty of grain and grass in the city, and the Anxi soldiers are all veterans, all of whom can fight well, if other personal force factors are excluded, this commander can hold Xizhou for more than half a year." Xue Li groaned.

"King Ming is unstoppable, and neither can I! I'm afraid Xizhou City can't be saved. Li Tiantu looked helpless and shouted in a low voice.

"There's one last way." Xue Li hesitated again and again, and said with difficulty: "Abandon the city to fight guerrillas." ”

This move is powerful for the overall situation, but it chills the hearts of 50,000 people, and it is indeed difficult to choose.

Li Tiantu was silent in thought.

"The king of Tubo, Ashina, drove the expedition in person, and there is the open-minded Lingyou as the commander, so he should not kill the people, this is the best way. Otherwise, even if we can hold out for half a year, I'm afraid that there will be no more of the 20,000 Anxi soldiers outside the city. ”

Xue Li analyzed the battle situation purely from the perspective of a soldier, weighed the pros and cons, and said: "Moreover, in this case, we can at least contain the Tubo people in the rear by 50,000 to 100,000 troops, so that even if the Tubo intend to invade Liangzhou, the strength will be greatly reduced."

"Wait, maybe there will be a miracle at the last moment."

Li Tiantu's eyes were dark, he had been in Xizhou for a long time, and he was going to regard himself as a complete Xizhou person, and he would never give up lightly until the end. Calculating the time, as early as a few days ago, Zhu Wenwu was afraid that he had already asked the emperor to serve the meridian flower, he didn't believe that Tianxuan couldn't see the strategic significance of Xizhou City to the entire Celestial Empire, and he didn't need to send a large army, as long as he had the courage to come up with enough chips to coerce the two Taoist real people in Louguan to come together, he was sure to drag the 300,000 army of Tubo in the Western Regions for at least half a year.

After half a year, maybe everything has changed.

Three days later, the secret agent from the front came to report that the 200,000 cavalry of Tubo had been less than fifty miles away from Xizhou City, and Li Tiantu still did not wait for the arrival of the two old Taoist immortals after all.

Carrying the infamy of the people in the city, after guarding Xizhou City for half a year, Li Tiantu and Xue Rang set out to evacuate the people who were willing to flee, and at the same time arranged for Qin Lan to gather all his troops at the gate of Dongcheng, ready to evacuate to the North Tianshan Mountain at any time.

Xue Li urgently evacuated the people in the city.

Li Tiantu took a thousand Xuantie Black Horsemen to take charge of the guard on the high slope outside the South City Gate.

"My lord, the Tibetans have converged."

Yu Bai Yu was condescending, and the snow eagle had just swooped down from the sky and landed on his emaciated shoulders.

Li Tiantu put a black horse in his crotch, he shook the reins and looked north, the wide Zhongcheng Avenue had passed for more than an hour, and there were still many people dragging their families to the east gate.

"Lingyou is already very interesting. If he drags us back before the arrival of the Tibetan army, the cruelty of this battle is destined to go down in history! ”

"The friends made by adults are really brothers who are like each other!" Yu Baiyu said with admiration, "My lord is not worthy of the country, and we have been abandoned in the Western Regions." ”

"Big mistake!" Li Tiantu said lightly, "The emperor is afraid that he is too busy to take care of himself now, as long as he can keep the dragon body to quell the civil strife of the Celestial Empire, and do his best to extinguish the dream of the Eastern Expedition of Tubo, it is already the most ideal state." The Jingshi is about to face a threat, so how can they take care of the Western Regions. It's my wishful thinking, the masters of the six sects of Buddhism and Taoism, probably only when Tubo hits the door will they make a move. ”

"My lord, you are the Buddha and Tao of our people from the Western Regions." The martial arts of the Western Regions have always been weak, and Yu Bai Yu saw hope in the young adult with extraordinary bearing in front of him.

Li Mo smiled, noncommittal, looked straight ahead and said with an awe-inspiring expression: "Bai Yu, the Tubo people are coming!" This is the second battle of our Xuantie Black Cavalry, one thousand against four hundred thousand, are you afraid? ”

Yu Baiyu stroked the delicate feathers of the snow eagle, shook his head and said, "Don't be afraid." In the eyes of the black knight, he has never been afraid of words. It's just that Bai Yu is not married yet, and it would be a pity if he unfortunately died. ”

The young black rider had a determined look on his face, but he had no regrets.

"Don't worry, adults know some numerology, and you will live longer than me." Li Mo shook the reins, and the war horse under his crotch neighed and charged towards the moat under the city.

A thousand black horsemen of the dark iron followed and roared down.
