On a simple dirt road paved with gravel on the Yan cave floor of the "Xuelin cave", more than 30 tall "snow moose" marched. These "snow moose" were as tall as elephants, with two black leather cans like water tanks hanging on the left and right sides of their backs, and some sundries such as luggage and wooden boxes piled up into a hill.

Even though all kinds of goods are piled on the back of each "snow moose", the traveling speed is not slow, the pace is strong, the breathing is uniform, and there is no fatigue.

It can be seen that this kind of moose has very strong endurance. The caravan guys and guards sit on the moose's back together for two or three days. They stagger and make people sleepy. From time to time, someone stretches his waist and beats.

At the end of the caravan was a moose with black spots. Sitting on its back was a black haired man with closed eyes and beautiful eyes. He was a Zhongzhou man. Although many Zhongzhou people came to the north, they were not common.

The son wore a black eagle suit, tied his hair and crown, and put a white jade hairpin in his head. It was Liu Yu.

Liu Yuta left beluga port by a servant cargo ship, passed more than 120 stations, and lasted more than three months to reach the terminal of the cargo ship route, "Panshan ice town".

Starting from the "winding mountain ice city" and heading east, he flew the sword in the desolate Han ice and snow forest for four days before reaching a remote town on Da Xuelin.

The destination of this trip, "NiuGuo town", is in the "Yan cave" deep underground of this remote town. After a few days of rest in this town, Liu Yu took an escort task from the adventure trade union in the town.

The mission is to escort a caravan to the underground cave. The caravan will sell spirit wine along the way and end at the "limestone town" in the depths of the cave.

According to the route map given by Kate, this is also the way for Liu Yu to "NiuGuo town", so Liu Yu will take over the escort task.

I don't like the reward of the hundreds of low-level spirit stones. It's mainly on the way. The underground caves and tunnels are complicated. Even if I have a road map and go on the road alone, I'm afraid I'll take a fork. It's not only a waste of time, but also very unsafe.

Although the route of the caravan is compared with the planned route map in Liu Yu's hand, it takes a lot of detours and a few more days, but it will eventually reach limestone town. When it reaches limestone Town, it is only half a day away from NiuGuo town. Liu Yu is happy to follow the caravan all the way.

Liu Yu has been underground with the caravan for seven days. The caravan was almost on its way the previous four days. She quickly passed through the "ice cave layer" and "mystery cave layer". After reaching the "inflammatory cave layer", the journey slowed down and began to sell spirit wine through various post towns.

It must be that the "ice cave layer" and "mystery cave layer" are too close to the ground, and the spirit wine can't sell well. Therefore, the caravan passed some post towns a few days ago and didn't stop moving.

The caravan mainly sells several kinds of spirit liquor. The largest quantity is a strong liquor called "Baifu". Liu Yu also tasted it during the rest of these days. It tastes strong, pungent, bitter and spicy. It is not Liu Yu's appetite. It is another fruit wine with higher price and light aroma. It is still delicious.

The gravel and dirt road at the foot is the post road connecting underground post stations. There are signs at the entrance of some corners to indicate the direction. Along the way, the post roads of "ice cave layer" and "mystery cave layer" are spacious and clean, paved by whole rocks.

Moreover, there are many pedestrians on the road. At the "Yan cave layer", the road becomes more and more simple, the stone road has become an earth road, and there are few pedestrians on the road. There is no human shadow for a long time.

At this time, there was a burst of cheers in front. I saw the road sign, and I will arrive at a post town not far ahead.

At the post station town, the caravan will rest for a period of time and sell all kinds of spirit wine on the moose back to all pubs in the town. Although the large black leather cans hanging on both sides of the moose are ugly, they are all pot space magic tools that can fill a large amount of spirit liquid, and the price is not low at all.

About half an hour later, the caravan arrived at a post town built against the cave walls and walls.

The town is small, with only one street. There are all kinds of shops on both sides of the street, and the houses are made of large and small stones. Therefore, except for a "servant branch" which is a three story wooden building, other shops and houses in the town are low bungalows.

After the caravan moved into a restaurant, the caravan manager began to visit the owners of various pubs in the town to sell the spirit wine transported by the caravan, while the free guards and guys ran to the pubs on the street.

Naturally, these people don't go to the pub to drink. They don't drink less along the way, but there are women in the pub in addition to wine.

Liu Yu naturally didn't like it. She asked the shopkeeper for a guest room and began to practice martial arts. According to the experience of these days, the caravan needs to stay here for at least half a day. Liu Yu just took the time to practice "psychic eye" and "Taoist soul Sutra".

But unexpectedly, this stay is three days. It turns out that starting from this town to the next post station, you need to pass through a huge cave grassland. The wolf disaster in this grassland cave is rampant, and there are a large number of second-order "cave wolves", and a fourth-order "wasteland wolf king" has been born in some big wolves, which is very dangerous.

From time to time, there were passing caravans and pedestrians attacked by wolves. They suffered heavy losses. If they didn't go to the next post station, there was only one way. Even if they took more time to detour, the caravan wouldn't take the risk.

After all, the whole caravan has too many people, goods and targets. With a "snow moose", the risk of being attacked by wolves is even greater.

For example, the caravan of more than 30 "snow moose" escorted by Liu Yu is not large in scale. The number of escorts is limited. They run back and forth underground and earn hard money.

Compared with those big business trips, nearly 100 "snow moose" can carry a large number of goods, and there are a large number of escorts. They can make a lot of money when they come down.

As a piggyback merchant in the underground caves, the small caravan only wants to have a smooth journey. If it loses several "snow moose" in case of danger, it will be a white trip. The price of each "snow moose" is as high as tens of thousands of spirit stones, so the caravan will stay in the town for so long this time.

Because they have to wait for other pack teams to arrive, small caravans usually travel in groups through the cave grassland. Several caravans start together. Although this makes the goal bigger, the guards of several caravans work together, so they don't have to be afraid of being attacked by wolves.

After all, "cave wolf" is only a general second-order spirit beast, and its combat power is not high unless it meets a large wolf group led by the "wasteland wolf king".

However, after the "cave wolf" has advanced into the "wasteland wolf king", its intelligence has increased. Generally, it will not take the initiative to attack the caravan with a large number of guards.

The fourth day later, the spirit wine caravan escorted by Liu Yu set out from the town. At the same time, there were two other caravans, one was a grocer who bought spirit materials and the other was a grain merchant who transported spirit rice. Together, the three caravans had nearly 100 "snow moose", which marched in a vast line like a long dragon.

An hour later, the caravan passed through a huge half moon cave. In front of it, there was an endless plain. The surrounding ground was covered with weeds, which was no different from the open grassland on the ground.

It was just a little dark. Looking up, the cave top was very high and dark, just like the dark night with dark clouds.

It is said that the cave grassland covers a wide range. The caravan can only reach the post station at the other end after walking for half a day. As the caravan moves inward, the scenery becomes more and more novel. The small heads of the grassland on both sides of the pack team are poked out from time to time, which is a kind of small spirit beast "cave rat" who is good at digging holes.

According to the accompanying guard, this grassland is flooded with cave rats with strong fertility and a large number. It not only attracts a large number of "cave wolves", "night Eagles" and other beasts that prey on them for a living.

There are also many adventurous servants who specialize in catching and selling these cave rats. These cave rats are very fat. The post station tavern usually bids seven or eight low-level spirit stones, which is also a way to earn spirit stones.

In addition, some scattered low nameless luminescent vegetation slowly appeared on the grassland. These vegetation emit light and various colors of light, which is very beautiful.

The most striking thing is that there are many glittering grasses like dandelions floating in the air, flickering and swaying with the wind, just like the stars in the night, like a dream.

Therefore, this open cave grassland has another poetic name "Yingfeng Grassland". If the wolf disaster is not rampant, I believe more adventure servants will come here, especially for those young lovers who have not confirmed their relationship.
