At the foot of Langshan, King Yue surrendered.

Although Zhennan Pass is dangerous, it only guards a mountain pass. The surrounding mountains are continuous, the garrison is limited, and the supply is inconvenient, and it can also be self-sufficient in settlements.

Lang Son is different. Although the surrounding area is surrounded by mountainous highlands and the terrain is steep, the Qiongqi River, which is the Zuoliu River, flows through, and the mountainous area also has a fertile mountain basin plain.

More importantly, this place is still a place where the key is locked. If you keep it, you can block the enemy in the north in the mountains of Vietnam. After taking the sutra, you will be flat and you can go straight to Hanoi, Jiaozhou along the River Valley Avenue.

Compared with Lang Son, Zhennan Pass is at most a front yard gate, and Lang Son is the main gate of the mansion. With the rare flat land of the river valley, Lang Son can completely subsist in farmland and self-sufficiency, and can also build a large city, garrisoning troops, grain storage, etc., so that an army of no less than 10,000 people can be stationed here for a long time.

This is why Qin Lang has been staring at Lang Son.

A place like Langsang is naturally not a land without a home. It is precisely because of the superiority of this place that there has always been fierce competition. Now the Yang family controls this place, and their ancestors also come from the Central Plains. Yang Jiyuan, the head of the family, was captured when Liu Yuan of the Sui Dynasty sent troops to attack Li Fozi, so he surrendered to the court and was granted military position.

Later, after destroying Li Fozi's power, he followed Liu Fang to conquer Linyi Kingdom invading Jiaozhou. He then went to Chang'an to pay homage to the emperor and served in Chang'an.

After the chaos at the end of the Sui Dynasty, he returned to his hometown in Jiaozhou, recruited the brave young man and others, and organized a group of troops. At that time, Zhou Shuxuan, a man from Langshan, made a rebellion, called himself the Black Emperor, and robbed the Yang family. So Yang Jiyuan brought his men to fight Zhou Shuxuan, and finally captured and killed the Black Emperor Zhou Shuxuan. Therefore, Qiu He, the prefect of Jiaozhi, simply appointed Yang Jiyuan as the fake military officer of Jiaozhi County, and participated in the military.

At that time, the Central Plains were in chaos and Lingnan was also in chaos. Yang Jiyuan simply suppressed the old village at the thief of the former Hei Emperor of Lang Sang, began to build a dock wall, recruit refugees, gather clan children, and also accommodated many Li Liaoman tribes. So for a moment, he was extremely powerful and did not dare to invade far and near.

Even the prefect Qiu He of Jiaozhi was very polite to him.

Later, when Qiu He surrendered to the Lingnan, Xiao Xian, the officials he sent to pay tribute, had not arrived in Jiangling, and the Tang army had already destroyed Xiao Xian under the leadership of Li Xiaogong and Li Jing, so Qiu He turned to the Tang Dynasty.

When Jiaozhi was changed to Jiaozhou, Qiu He first became the general manager of Jiaozhou, then the governor of the Governor's Office, and then the governor of Jiaozhou. For several years, Qiu He still led the Jiaozhou area, and Yang Jiyuan, who was close to Qiu He, also controlled the Lang Son area.

After Qiu He was conquered and entered the court, Yang Jiyuan no longer held an official position, but retired and returned home. It is forgivable that Shanwu Wall has not only not disbanded in recent years, but has become bigger and bigger.

"What did Yang Jiyuan say?" Qin Lang asked.

A guy like Yang Jiyuan is so old, but it is even more difficult to deal with. These people are old people, and have seen all kinds of scenes, so the way they deal with the barbarians sometimes doesn't work for them.

The most important thing is that the Yang family’s Lang Sang Dock Wall is very powerful.

The stuff like Wubi, also known as Wubi, was actually popular in the Central Plains. From the Han Dynasty to the Wei, Jin, Southern and Northern Dynasties, there were many wars in the northern Central Plains, so many powerful local tribes and powerful people chose some dangerous places, either high mountains or deep valleys, to build Wubi forts.

This kind of dock is a small castle with walls, trenches, and even corner towers.

Outside the fort is the cultivated fields. The dock owner has a large number of troops and family soldiers in the fort, and many dock people are also attached to it.

Although Emperor Guangwu of Han once ordered the destruction of such a fort, it was repeatedly banned. Especially at that time, when the Qiang and barbarians attacked each other, the border people spontaneously built the fort and formed a group to defend themselves.

By the end of the Western Jin Dynasty, the Five Barbarians in the north invaded China, and the people were even more indifference. Therefore, the Han landlords and powerful people built forts, organized rural soldiers, gathered forts, and defended themselves in danger.

When facing ordinary thieves and hungry people or small groups of Hu soldiers, this kind of fortress can often defend itself. If the other party wants to forcibly capture these heavily guarded fortresses, it is not easy for the other party to fortresses, so it either bypasses or blackmails some money and food.

During the darkest period of the Five Barbarians' Invasion of China, there were only three million Han people left in the north, and most of these Han people survived on these forts.

Later, the forts of these Han Chinese powerful people in the Central Plains were also attracted by the Humans, so they also followed suit and set up forts to live in.

In the chaotic times, docks were very useful, but after the Sui and Tang Dynasties, docks had gradually decreased, and the rest were only large docks that had already formed large scale.

For example, at the end of the Sui Dynasty, Li Shimin and Liu Wuzhou fought in Baibi in Hedong. Baibi, which is actually also called Baiwu, is a large dock fort.

On the border, the fort was passed down.

Especially for the forts like Lang Shan Dock Fort, because they are in a wilderness and are not under the jurisdiction of the court, there are no laws here. The dock owners are local emperors. They do not pay taxes to the government and are not subject to the laws of the government.

There is a set of rules in the dock. The dock owner is actually the landlord, and the dock people are the dock owner's tenants, and the docks also have village soldiers and troops in the docks, which are equipped with armed forces.

In Langshanwu Fort, the main body is actually the Yang family, so many people in the Yang family are landlords.

It was just because of the rebellion of the Sui Dynasty that the Yang family also conquered many small mandates, so there were also many barbarians in the fort who were attached to the Yang family.

There are houses and markets in the dock, and even warehouses and prisons are fully prepared.

Especially because it has become more stable in recent years, Lang San is guarding between Jiao Yong and entering Jiaozhou by land. Lang San is a must-pass place, so commercial transactions here have been quite lively in recent years.

The power of the Yang family has further expanded.

Compared with the barbarians' villages, the significant difference between the docks is that their defense capabilities are very strong, not as good as the barbarians' villages, but they are actually simple villages. The docks are big and small, and the small docks are like the Hakka Tulou in later generations. In fact, they are simple versions of docks. The large docks can accommodate thousands of people and become a fully functional castle.

Many simple villages gathered around them, so a powerful force could be formed.

The late Eastern Han Dynasty and the late Western Jin Dynasty were the era of many forts in the Central Plains.

The Yang family redeveloped the forts that were from the Central Plains in Lang Son, Jiaozhou, and it was even far beyond the forts that were from the forts that were from the past.

There are thousands of people living in the main yard of Liangshan, and there are twelve yards scattered around. If there are some remote mountains in the mountains that are dependent on the Yang family and some Han immigrant villages, the Yang family is in the mountainous area, with more than 20,000 people.

Before coming to Jiaozhou, I looked at the records of the imperial court's Ministry of Revenue and found that there were only 20,000 households in Jiaozhou. But when I really came here, I found that the record was inaccurate at all.

The 20,000 households only had the population of Jiaozhou City and several county towns, plus the population of some Han villages outside the city, they did not include the barbarians, nor did they include the descendants of Han immigrants like the Yang family in the mountains.

In fact, there are many people on the mountain stream.

One Jinjidong Tribal Alliance has a population of more than 10,000, and now one Langsang Yang family has more than 20,000 people. This is just in the mountainous area.

Qin Lang sent someone to invite Yang Jiyuan to Zhennanguan to attend his concubine ceremony, but Yang Jiyuan did not come.

A few people sent to give some gifts, and Ah Huang was so angry when he talked about the gift.

"Then he gave me a few turtles, a few jars of willow pulp, and some things called earthy meat. What does this mean? Send the beggar?"

"Oh, by the way, the old turtle named Yang also sent someone a woman with black teeth, who was also black and thin."

Qin Lang went south, and the barbarians either gave pearls or gold, or ivory, rhinoceros horns, or agarwood.

Qin Lang, who gave turtle feet, willow pulp, earthy meat and black-toothed women, really didn't meet.

Yang Jiyuan is also an experienced handsome Han chief. What does this mean?

"Take me a look at the turtle feet you said!"

"I have someone to throw away anything to see."

"Let's take it to me first. I don't believe that Yang Jiyuan really gives me a few turtles."

Ah Huang went back cursingly and found the thrown things again, but he carried them over and looked disgusted.

"We came from Chang'an, what good things have you eaten? Do you want to eat turtle feet?"

Qin Lang asked Ah Huang to take out the turtle feet he said and put them on the table to watch. After Dugu Yanyun and others heard about it, they all came to watch.

A few strange things were placed on the table, and they looked like turtles, but their feet looked like crabs, but they had twelve feet, all of which were growing on their abdomen.

Turn it over, and there are still seeds on the abdomen, which are dense and small.

At this time, Nong Cunxin came over, "This is called a school fish. The mother is carrying the male. The sesame-like sons under her belly can be picked out to make sauce and eaten. It is very delicious."

Qin Lang thinks that this thing is indeed very distinctive in length, but when you look closely, it seems to be similar to a folded stingray. This kind of fish is commonly known as a manta ray, and it is very flat and patterned. There are many categories of manta rays, but the general ones are still very different from this one. Qin Lang thinks that even if this is not a manta ray, it should be a close relative.

It seems that Yang Jiyuan gave him a turtle's foot and it is wronged.

Nong Cunxin said that this is called school fish, which is very fresh, especially the boy who is under the belly makes sauce more delicious. It seems that this is a local specialty of Jiaozhou. Although Lang Son is a mountainous area, it is not far from the sea after all.

"What's that kind of rusty flake?"

The Yang family sent someone to give gifts to Qin Lang that the earthy meat flake is made of earthy meat.

"What's the thing about earthy meat?"

"A kind of sandworm, sand and soil live in the cave, like silkworm pupa, with no head or feet, narrow front and back, soft body, and squirming." Nong Cunxin said quickly, "This thing is delicious and can be eaten with grilling."

The Yang family came to the Yang family and said proudly, "My earthy meat flake is not a meat sauce made of ordinary earthy meat. This was obtained by my home owner when he built a dock wall by Qiongqi River in Langshan. When he was digging the soil to build a foundation, he dug a sand hole. It was a earthy meat king, dozens of feet long and more than meter thick, like a earthy meat mountain. My home owner first fed the earthy meat king various precious medicinal materials. After three years of feeding, he was slaughtered and made into earthy meat flakes. This is a unique dish. Only this batch, these flakes have been eaten after three years. They are both fragrant and fresh, and they also have the purpose of strengthening and health care. My home owner specially sent Nine Tan to Xuan Xiang."

After hearing the explanation, Qin Lang said in his heart that if according to what Nong Cunxin said, this earthy meat is just an ordinary sandworm. It can be eaten and tastes good, but what the Yang family said is too exaggerated.

It is dozens of feet long and more than meter thick. This is really the king of earth and meat, or even the emperor of earth and meat. However, Qin Lang doesn't think it is very credible. How could a sandworm without shells grow so big?

I also dug up when digging the foundation of the docking fort. This old guy is really good at fooling people.

As for the other two gifts, catkin juice and black-toothed women, it is actually not that exaggerated. The catkin juice is not juice squeezed with catkins, but grinds the seeds wrapped in catkins into a slurry, and then uses this slurry to make wine, which has a unique flavor.
