After entering Diao and Iwaju, the roads are all through the mountains and valleys. Most of the roads are surrounded by mountains on one side and surging rapids on the other, which are much steeper than the roads in the Cockscomb Mountains. Although the rivers here are not as wide as those in the plains, they are very turbulent and cold, and the water roars down through the mountains, making a loud roar. The folk customs here are fierce, most of the village villages are built in the places where it is easy to defend and difficult to attack, the houses are all made of stones, and the towers that are tens of meters high are often built in the dangerous places, and the two states of the towers and rocks are also named after this. The volume of armed caravans in the two states is not large, on the one hand, because of the war, the Qian family has been doing business here for a long time, and there are no sales agents here. In the Yibo area, the goods are generally sold to local merchants, who then resell them to the villages. In fact, the local merchants did not make this difference in vain, but took huge risks. In addition to the sparse population of the mountain and high roads, but also because there are many bandits here and extremely vicious, killing people and stealing goods is commonplace. This is also the reason why the Qian family's caravan stopped in Lizhou most of the time.

As soon as they entered the border between the two states, the armed caravans were constantly harassed. The robbers, seeing that the armed caravan was outnumbered and could not be attacked head-on, attacked or blocked the way, but they were all frightened by the explosion of firearms. Although these bandits could not succeed, they did not give up easily, and followed them for a few days before they could disperse. This made everyone on high alert at all times, and they were also exhausted. Even though the caravan was cautious along the way, several people were injured by stones pushed down from a high place by bandits, several mules and horses were killed, and even folding shields were smashed. Knowing that he could not entangle with these bandits, Boss Qian ordered the march to be quickened, selling goods and buying food only in the main villages along the way. The villages along these roads are only a few hundred people, and the small ones are only a few dozen people, and they are not able to rob armed caravans at all, but can exchange agricultural products for daily necessities, so naturally there will be no idea of robbery. It was late April, and the border between the two states was also in full bloom, and the climate was not cold. The caravan did not enter the village as a precaution, but camped outside the village for the night. Boss Qian ordered people to strengthen vigilance, so although it was difficult along the way, there was only no danger.

On the other hand, the transaction volume is not large, because Boss Qian wants to keep the goods, and goes directly to the arrow furnace - that is, Kangding in later generations, and even goes to the grassland area of the Tibetan region to exchange horses. Without the middlemen to make the difference, the number of horses exchanged for the goods on the grassland was at least several times that of Diao and Yanzhou. Since the disintegration of the Tibetan Dynasty, the Tibetan region has been divided. This is especially true in the grassland areas of the Diao, Yan and Tibetan regions, where there are many large and small tribes, and they are constantly attacking each other. Because the low productivity of the bitter cold land cannot support the standing armed forces, the large tribes here are only a few hundred capable soldiers, and the small tribes can only fight samurai, and the armed caravans that really fight also have the strength to fight, which is also one of the reasons that support Boss Qian's adventure to continue to advance. Another important reason why Boss Qian continued to go deep into the Fan District to buy horses was that Nima, the head of the arrow furnace, was his friend of life and death and a business partner for many years. Counting from their fingers, they haven't seen each other for more than ten years.

Dajian furnace is located in the narrow valley area surrounded by three mountains and two rivers, is the throat of the Han land leading to the depths of the Tibetan region, this place name first appeared in the Shu Han period of the Three Kingdoms, is the transliteration of the local local language "discount Zhu". This place is located at the junction of Shengbo and Shubo, the Diao, Yanzhou before the arrow furnace is the ripe Fan, and after the arrow furnace is the Shengbo area of the grassland. Although Diao and Yanzhou are also dominated by the Fan people, they are deeply influenced by Han culture, and they are civilized and enlightened mature Tibetans, and they have some sense of rules. Take robbery as an example, the local officials and leaders of the two prefectures of Diao and Yan knew that openly robbing caravans was killing chickens and eggs, and would directly cut off their own sources of taxes and necessities in their jurisdictions. In addition to asking for more money to buy roads, the local officials in these two states did not do too much out of the ordinary, and even cracked down on bandits in their jurisdictions. For these greedy landlords, Boss Qian didn't care, and simply used money to open the way to peace, and also laid the foundation for future business. The grassland area is different, the living environment here is even worse, the law of the jungle is believed, and there are even more bandits, and even some tribes are also bandits, and the head chief is the leader of the bandits. It is extremely remote and sparsely populated, and even during the period of Tibet's power, law and order did not take root here. The only fate of the Han caravan that dared to come here to do business was destruction, and even the local merchants often died and lost their goods. Because few caravans went to the grasslands, the nomadic tribes had to trade with the agricultural areas, mostly in the relative safety of Dajian furnace or Diao, Yanzhou, or even in Lizhou.

After arriving at the archery furnace, Boss Qian ordered Qian Laosan to choose a flat place to camp, and went to the village to meet his head friend. Li Gongzi, who accompanied him, led his platoon and carried gifts for Nima and the villagers—silk, tea, salt, and fine porcelain. Like most of the villages in the Tibetan area, the residents of the Arrow Furnace did not build the village in a river valley with easy transportation, but built it on a platform halfway up the mountainside, not only to defend against enemies, but also because of the frequent floods, mudslides, and even earthquakes in this area.

The air in the cold land of the Tibetan region is thin, and the people in the plains are quite uncomfortable here, and they will feel stuffy and short of breath when they move a little bigger, but the personnel of the armed caravan often come and go here, and they can also adapt to the mountains and rivers all year round. Seeing that his old friend was anxious, Boss Qian was in a hurry when he went to the village, and when he approached the gate of the village halfway up the mountain, he was already out of breath. After bending down to catch his breath, he straightened up and found that the gate in front of him was still closed, and the wall was full of native soldiers with knives and sticks. The situation in front of him made Boss Qian very angry in his heart: "Okay, you Nima, I came all the way to see you, and I actually gave me a closed door." Immediately shouted loudly to the wall in the local language, asking Nima to come out to meet him. After shouting for a long time, the village did not reply, and the native soldiers on the wall looked at him blankly. At this time, Li Gongzi and others had already arrived in front of the village with gifts, and Boss Qian pointed to the gifts and shouted to the wall in local language: "Nima Touren, I brought you gifts, as well as salt and tea goods for trading, don't you buy and sell now?" ”

The luster of porcelain and silk made the eyes of the soldiers on the wall flash with greed, and Boss Qian's words made them even more commotion. What started as a few people chattered with each other, then gradually turned into a whisper of the entire wall, and finally into a loud noise, and the array became skewed and scattered. The loud clamor of the soldiers did not last long. As a thin man in brocade clothes walked up to the wall, the soldiers automatically moved out of the way, and their eager eyes turned into cringe. Boss Qian looked at it and was overjoyed, the person who came was Nima's housekeeper Adam, so he called out, "Adam, how is Nima's head?" This Adam didn't understand Boss Qian, he first coldly swept the people under the wall, and then squinted and looked carefully at the gifts carried by Li Gongzi and others, and then stopped his gaze on Boss Qian, and said: "Nima Touren died of illness a few years ago, and Young Master Zelang doesn't know what happened, and I am now the head of this village." Now that the arrow furnace is no longer trading, Boss Qian, please go back", and turned around after speaking.
