Tai Chi Hall, Wu Cong's office.

"Your Excellency, the two dancing girls have already left Chang'an, and someone saw that they got into the carriage of Sun Shunde, the head of Pi Guoxiang, and went out of the east gate of Chang'an City and headed towards Luoyang.

After inquiry, the eldest grandson Shunde was going to Luoyang to deal with some business matters. ”

The person sent by Wu Cong to Qingyunlou for questioning has returned and is reporting to her.

Wu Cong asked them to step down, and came to see Li Su.

Li Su heard that the eldest grandson Shunde had also left Chang'an, and felt that the problem was a bit serious.

For more than ten years, the eldest grandson Shunde has served as the highest military governor in Luoyang, where he has great influence. This time to retire him as an adviser to the General Staff, it was a measure taken to eliminate his influence.

The dissatisfaction in the heart of the eldest grandson Shunde is obvious, at this time, he returned to Luoyang, I am afraid that it is not just as simple as dealing with his family's business affairs in Luoyang.

The three most important cities of the Tang Dynasty, Chang'an, Luoyang and Yangzhou, if Luoyang was in chaos, its influence would be too great.

Only then did Li Su find that he had been running the Tang Dynasty for so many years, and there were still so many internal hidden dangers, and the current situation was similar to the situation when Emperor Yang of Sui conquered Goguryeo.

Emperor Yang of the Sui Dynasty mobilized a large army to attack Goguryeo, but there was internal turmoil, which eventually led to the fall of the Sui Dynasty.

Li Su instructed Wu Cong to send people to check on the movements of the eldest grandson Shunde.

Soon, Wei Chigong came again, and what he brought was still not good news.

Hou Junji's army on the Western Route was originally progressing smoothly, and the Tubo people were defeated and retreated.

After a period of research, Lou Xianzhi, the commander of the Eastern General's Mansion, a famous Tibetan general, found that the Tang army was well-equipped and had strong combat effectiveness, but they relied too much on baggage.

Lou Xianzhi tried his best to avoid a head-on decisive battle with the Tang army, and he took advantage of the terrain to disperse his troops into troops ranging in size from more than 100 to several thousand, and took advantage of the terrain to start a guerrilla war with the Tang army.

The Don army was unfamiliar with the local terrain and repeatedly suffered losses, and without large-scale battles, the losses were quite serious.

In one battle, the artillery unit of the Tang army was attacked by the Tibetans and lost two cannons.

The situation encountered by the Su Dingfang Department of the North Road Army was not much different from that of Hou Junji's department, and the progress was very slow.

What about Gao Xianzhi, who Li Su had high hopes for?

After Gao Xianzhi received sufficient material support, he organized troops to dig south to collect snow and gravel. After more than a month of hard work, the road out of the valley was finally opened.

When the Tang army appeared under the city of Geji, they found that the Tibetans had already fled. Gao Xianzhi led the army to rest here for two days, preparing to continue south.

That morning, Gao Xianzhi suddenly received a report that a large number of Tibetan troops had been found south of Geji City.

Gao Xianzhi hurriedly ordered the whole army to assemble and prepare for battle.

In the field southeast of Geji City, Gao Xianzhi led the army to complete the formation, waiting for the arrival of the enemy army.

In the morning on the plateau of northern Tibet, the sun was shining, but there was still no warmth, and the cold wind blew the battle flag of the Tang army, making a loud noise.

On the front of the Don Army, a large number of troops appeared.

With the help of binoculars, Gao Xianzhi carefully observed the dynamics of the enemy army, and when he saw the enemy's outfit and banner clearly, he couldn't help but be surprised.

The enemy on the opposite side is not the Tubo people at all, but the army of the Kingdom of the Ring Sun!

The Tang army was strong and well-equipped, and the enemy army on the opposite side was only about 50,000 people, and Gao Xianzhi was completely sure that it would be defeated or even annihilated.

However, after all, it was not the army of the Tubo people on the other side, and he rashly started a war with the army of the Ring Sun Kingdom, and Gao Xianzhi was not authorized.

Gao Xianzhi didn't know how to deal with this situation for a while.

How did the army of the Kingdom of the Ring of the Sun appear here?

It turned out that in order to get the help of the Ring Sun Kingdom, Songtsen Gampo didn't care about the accident of Lu Dongzan and others in Tibet. Another mission was sent to visit the city of Qunu.

This time, the Tubo people not only benefited Wang Xiao of the Ring Sun, but also ceded part of the territory in the southwest in exchange for the support of the Ring Sun Kingdom.

The father and son of the king of the Ring of the Sun thought about it again and again, thinking that what the Tubo people said was reasonable, once the Tubo perished, the Kingdom of the Ring of the Sun would directly face the iron hooves of the Tang Dynasty.

Faced with the conditions offered by the Tibetans, the father and son of the king of the Ring of the Sun finally made up their minds and sent troops to participate in the war.

Gao Xianzhi sent people who were familiar with the Chinese language of the Ring Sun King to negotiate and ask them to give way, but as a result, the people said that the land here was already the place of their Ring Sun Kingdom, but they did not give way.

Gao Xianzhi couldn't figure out to what extent the Kingdom of the Ring Sun was involved in this war. Without receiving the authorization of the imperial court, he did not dare to rashly start a war with such a powerful country as the Kingdom of the Ring of the Sun.

Gao Xianzhi thought twice about it, decided to temporarily occupy northern Tibet, and sent people to ask the imperial court for instructions.

Tai Chi Palace, Li Su's study.

Gao Xianzhi's situation, the sticker has already reported to Li Su.

Immediately afterwards, Wei Chigong came again.

Seeing Wei Chigong, Li Su couldn't help but smile bitterly, he must have come to report the depressing news again.

Sure enough, Wei Chigong said: "Your Majesty, Xue Rengui sent a letter saying that the Arabs had rebelled against a province of the Persian Empire.

At the same time, the Arabs continued to increase their forces in the puppet regime they supported, the Kingdom of Potter. It is said that the caliph had the intention of mobilizing a northern expeditionary army to the south to settle the Persian Empire in one fell swoop. ”

Wei Zheng said: "Your Majesty, the situation is so chaotic now, if it doesn't work, temporarily stop the war against Tubo, and solve the domestic problems first.

Or abandon Persia and concentrate all your efforts on the Tibetans.

Otherwise, the stall is too large, and it is really possible to follow the old path of Emperor Yang of Sui. ”

Huang Furui agreed with him.

Wei Chigong objected, he said: "The attack on Tibet, which has been prepared for so long and mobilized so many people, cannot end in such a hurry. ”

Wang Xuance said: "The matter of Persia cannot be abandoned, I bet that once Persia is annexed by the Arabs, their next target is the Anxi Protectorate, and it will not be long before the entire Western Regions will be lost."

What is even more serious is that the dozens of ethnic minorities in the Western Regions, with the ability of the Arabs to assimilate into religion, will soon lose their influence there and completely lose the Western Regions.

The Han will lose that territory in the Western Regions forever. ”

Cheng Yanjin, who was invited to attend the meeting, said: "I agree with the opinion of Da Lao Hei, how can there be a reason to withdraw after half of the battle."

Aren't you just worried about chaos in the country? It's not that I'm bragging, but I'm armed police force, and I'm afraid that they will turn the sky upside down? ”

The ministers discussed for a long time, and finally focused their attention on Li Su.

How should Li Su face such a complex chaos?
