Taihe City is a city that is extremely difficult to be captured by foreign forces, and the ease of defense and difficulty in attacking is definitely the most obvious sign of this city.

Because of its complex terrain, Taihe City is not like the common square city in the Central Plains, but because it is built on the slope between the peak of the Buddha of Cangshan and the Five Finger Mountain, thus forming a unique shape city with only two city walls.

The steep Cangshan Mountain forms a natural defensive barrier to the west, and the vast and infinite waters of the Erhai Sea to the east, two natural strategic barriers, which are enough to make Taihe City unnecessary to spend time and money on defense in these two directions.

The two city walls in the north and south are based on the terrain, winding like two long dragon-like solid city walls, lying between Cangshan Mountain and Erhai Lake, forming a fortified city that is easy to defend and difficult to attack.

Similarly, when Shelong was still the king of Nanzhao (Mengshe Zhao), he built two small cities less than 100 miles away from Taihe City, one south and one north, and named them Longkou and Longwei two cities, so as to defend Taihe City together, making Taihe City more impregnable.

And Lawless, Yuan Shuji, Guo Shi, Shelong, Xinuluo, Luo Shengyan and others are now standing under the gate of Longkou City, waiting for Li Hong's arrival.

The city is not very big, the winding small streets, quite the artistic conception of the water town in the south of the Yangtze River, plus the land of Yunnan and Guizhou is already full of mountains and rivers, small bridges and flowing water, ponds and small courtyards, thatched houses or rammed earth rammed yellow walls, here it seems, it is also quite a smart artistic conception.

From time to time, the people, dressed in various costumes, would sneak out of the poorly sealed log windows to look at the passing army, but none of them would come out to investigate.

At this time, the people of Nanzhao were not separated into various ethnic groups as they were in the previous generation, and now most of them regard themselves as the cuan tribe and call themselves the descendants of the Ban clan.

The formation of the Ban clan was in the Spring and Autumn Period, and the descendants of Ruoao of Chu State multiplied, and according to legend, their ancestors grew up eating tiger milk, so they took their tabby spots as their surnames.

Li Hong didn't know anything about this, and while listening to Shelong telling their history freely, he sat on horseback and looked at the Erhai Lake and Cangshan Mountain connected to the sky in the distance.

Sheron's rhetoric is obviously very convincing, after all, the meaning of the word "tiger" here is the meaning of the tiger, and it can be basically determined that their ethnic group is a clan developed by the descendants of the Ban clan as the main body.

At the end of the pre-Sui period, with the decline of the Eastern Plan, the West Plan once again led to internal division, thus forming a tribal state named after their royal title: the Mengwei Edict, the Yue Analysis Edict, the Langqiong Edict, the Dang Edict, the Shi Lang Edict, and the Mengshe Edict.

The Mengshe edict is often called the Nanzhao because it is in the south of the other five edicts.

In addition, its strength was stronger than that of other tribes, and when Li Hong sent people to give Nanzhao enough military support when they were in turmoil, he assisted Nanzhao to unify the other five edicts and formed the current Great Nanzhao.

Li Hong understood the purpose of Shelong and Xinuluo telling him about their history, which was to tell himself vaguely that they had unified the other five edicts, although they had their own support at that time, but they also had absolute legitimacy here just like the Tang Dynasty ruled the Central Plains.

Li Hongduan sat on the back of the horse and did not speak, according to their Nanzhao etiquette, after the etiquette of the gods and ghosts wearing all kinds of abnormal costumes, he stepped on the back of Xinuluo and slowly got off the horse.

After Xinuluo waited for Li Hong to stand firmly on his feet, he got up from the ground, and instead of a trace of annoyance at the big footprints on his back, he looked extremely excited.

Especially when his son Luo Shengyan watched him get up, the dazzling footprints on his back, and wanted to help him shoot it off, he was even severely stopped by Xinuluo with his eyes, so it can be known that Xinuluo is still quite jealous of Li Hong's arrival.

The city gate of Taihe City is not very tall, but as the remains of the ancient city of Dali in the previous generation, most of the streets and alleys are made of hard stones, and even the main body of this city gate is also made of stones, only in other places where the terrain is steep, it will be used to build the city wall with loess tamping.

Stone buildings abound throughout the city, and even the winding alleys under your feet are also paved with stones, but after years of trampling, they have become slightly uneven, but on the whole, especially walking in the narrow alleys after the rain, is like walking on a mirror.

Xinuluo is famous for his penchant for beauty, and even his son has inherited his fine traditions, and all the women in Taihe City who have some beauty will be forcibly recruited into the palace by him, and if they like it, they will stay in the palace, and then they will send someone to give their families a sum of money.

If you don't like it, it's not bad, and you will let her go home, but many times, the woman who gave up by Xinuluo will be snatched away from the middle of the road by his son Luo Shengyan and become Luo Shengyan's private thing.

Li Hong walked in the forefront, followed by Xinuluo on the left, followed by Shelong on the right, and behind him, there were two people who had not appeared for a long time.

The two quietly recounted to Li Hong what Xinuluo had done in Nanzhao, and reminded Li Hong from time to time that this time he came, Xinuluo stationed a large number of soldiers and horses in the north of Taihe City, that is, their Longwei City, to prevent the leaders of the other Five Zhaos from coming to Taihe City to meet him.

Taihe City also has the existence of a palace, after Shelong passed the Mengshe edict to Xinuluo, the young Xinuluo after getting the support of the Tang Dynasty, suppressed the five edicts in one fell swoop, and after unifying the entire tribe, he began to follow the Tang Dynasty and build a palace.

And once a person enjoys the supreme pleasure of supreme power, then his ambition will become greater and greater, just as Xinuluo, after ruling the entire tribe, begins to be dissatisfied with continuing to act in the eyes of the Tang Dynasty.

Instead, he began to secretly communicate with some forces in Tibet who wanted to restore their Zampu, including some forces in Zhenla, and Princess Fangling in Jiannan Province, so trying to get close to all forces, hoping to completely break away from the control of the Tang Dynasty, so as to become an independent kingdom like Zhenla.

The Tang Dynasty's Annan Protectorate is in Song Ping Mansion (Hanoi, Vietnam), which is not very close to Taihe City, not to mention that the Tang Dynasty did not deploy too many troops in Annam before Li Hong's dictatorship, but after Li Hong helped Xinuluo unify the Southern Zhao, he symbolically placed troops in Song Pingfu in Annam to prevent the threat of Zhenla to the Tang Dynasty.

In addition, the distance from Song Ping Mansion to Taihe City is long, and the terrain is complex, humid and sultry dense forests are extremely common, and the endless mountains are mixed in it, and it takes a month to go back and forth, so the Annan Metropolitan Protectorate obviously has less deterrence and containment to Taihe City, thus giving them more opportunities to win over others to help themselves.

Liu Yanyou is now in Songping Mansion, and Pei Xingjian and Chen Jingzhi's warship sailors are also at the nearest pier to Songping Mansion in Lingnan Road.

"How much do they know about the affairs of Chengdu Mansion?" Li Hong rightfully stood in the center of the palace gate, accepting the ministers of Nanzhao, under the leadership of Xinuluo and Shelong, to pay homage to himself.

"The slave has tried his best to let Jingwei cut off the messengers along the line, and from the observation of the past few days, it is obvious that Xinuluo has not noticed any movement, but ...... It's hard to say about the other tribal leaders of the Five Edicts, Lingnan Dao is too big, and it is even more difficult for all the places of the Six Edicts to be supervised by Jingwei, even if Miss Bai later secretly mobilized the seventy Jingwei, it is still not enough. Stunned stood behind Li Hong as usual, watching Nanzhao's guard of honor continue the lengthy ceremony of welcoming the crown prince.

"When Chengdu Mansion, Jingwei was not enough, but there was no way, the stall was too big, but this is an interlocking thing, if you don't solve the things in Chengdu Mansion, you can't get here, if you don't solve the things here, you can't face Zhenla without scruples, how is the prince of Zhenla? Did Shinura ask? Li Hong smiled and nodded at the fine slave who was standing at the bottom of the steps, indicating that he was satisfied with the solemn ceremony that welcomed him.

He asked twice, but until now, he didn't know where the three were being held by the slaves. However, Liu Duhu is also urging the slaves and maids now, if you want Jingwei to sneak into Zhenla, it is the best opportunity to return their prince first, I hope Your Highness, you can consider it carefully. Mangzhong lowered his head, and the shinuro below could only see his lips moving, but he couldn't hear what they were saying.

Therefore, Xinuluo smiled with Li Hong on his face, but his heart was full of ups and downs, and he didn't know what the eunuchs around Li Hong were plotting with Li Hong, or what kind of orders he was receiving from Li Hong.

"Then reveal it to Xinuluo, remember to be passive, let him think that he found it himself, let Zhenla inherit Xinuluo's favor, as for the infiltration of Jingwei, there is no need to jump over Hengshan for the time being, inform Pei Xingjian and Chen Jingzhi that the merchant ships coming from Quanzhou and other places should be put some of them, and let Jingwei follow the caravan into Zhenla from the waterway." Li Hong watched as the lengthy ceremony was finally completed, and then after Xinuluo and Shelong had obtained their consent, they slowly climbed the steps and began to lead the way in front of them towards the palace.

The Tang Dynasty soldiers behind him, as well as the officials of Nanzhao, were divided into two rows, closely following behind Li Hong and others, and began to walk towards the main hall of the palace under various ghostly talisman-like honor guards.
