These few times, Yu Shan has brought in a lot of various tools. For example, this time, he brought in a powerful composite bow, which is a big killing weapon.

If you use it well, Yushan can accurately shoot and kill 16 ferocious beasts, no matter how powerful they are.

This is mainly because the number of spider claws is too small. If there are too many, Yushan occupies favorable terrain and can destroy a population of ferocious beasts.

"I didn't expect that among the ferocious beasts, the most useful essence and blood are. In this way, I will collect more essence and blood in the future."

Yu Shan’s biggest gain when he went back this time was that he learned to brew beast blood wine, so Yu Shan did not make the wrong choice when he learned to brew wine.

The greatest function of beast blood wine is to replenish qi and blood, strengthen muscles and bones. If you use some spiritual beast bones, such as tiger bones, deer antlers, and animal blood, you can make the three-yang bone wine that strengthens muscles and bones.

Although these beast blood wines can replenish qi and blood, their greatest effect is to strengthen the body. For example, the beast blood consumed at the mountain increased his strength by more than 100 kilograms.

"The legend of blood bath in the valley of Hundred Beasts is true." Yu Shan heard from the fifth knife that in addition to swallowing the blood of the spirit beast, it can also be used to take a bath. It can take a bath like a medicinal bath. This can nourish the whole body, strengthen the muscles and muscles of the whole body, speed up the body's metabolism, and eliminate body damage.

Yu Shan only heard that the dragon blood can make people indestructible. In this way, the blood of the spirit beast should also have some effect.

Since it has a useful function, it must be used. Anyway, there are abundant resources here, so this time, Yushan came here for the spiritual beast resources here. After all, Yushan doesn’t know the medicinal materials, so it’s better to make some visible and tangible things.

The most useful thing Yu Shan brought in this time was a hot air balloon, or an airship, mainly used to transport prey.

Hot air balloons cannot fly very high, but it is enough to fly two hundred meters away. In this jungle, there are not many trees above one hundred meters, and most trees will not exceed two hundred meters, so it is the most suitable in a sky of two hundred meters.

There is no danger in this airspace and no wind, which can easily stabilize the hot air balloons, so Yu Shan is not afraid that the hot air balloons will be blown away by the wind after they take off.

The reason why we carry hot air balloons instead of real airships is because helium is not easy to carry, but the use of hot air balloons mainly consumes fuel. Some of this is in the secret realm of the East Wilderness.

The hot air balloon will expand as long as it is inflated, while the hanging basket below is very small and can only hold two or three people. As for transporting materials, it mainly depends on a large number of slings.

These slings are driven by a fixed pulley under the hot air balloon, which can lift the prey below. Of course, controlling the height of the hot air balloon can also bring the prey on the sling into the air.

After preparing the hot air balloon, Yu Shan sat in the hanging basket. He looked around and it was getting dark. At this time, all the ferocious beasts did not come out. It was the safest moment.

"I don't know if there are any flying beasts at night." The biggest enemy of the hot air balloon is the flying beasts. As for those on the ground, the possibility of them jumping to a height of two hundred meters is very slim.

I collected some dead wood and put it in the hanging basket. It felt enough to burn for a few hours. I lit the fire in Yushan and started to inflate it.

The hot air balloon brought by Yu Shan is also quite advanced. As long as you rush up, you don’t need to continue to heat it vigorously and float in the sky. Because there are controllable and adjustable valves inside, it can keep some hot air. So just need to heat it a little, and the hot air balloon can be kept flying in the air.

It will naturally take some time to ignite the fire in the early stage, but the trees here contain some spiritual energy, so they burn very violently.

With more heat provided, a piece of wood with a very short piece can burn for a long time. Therefore, Yushan collected about 100 kilograms of wood, which was enough for the hot air balloon to fly for several hours.

The air heats up quickly, and the hot air balloon slowly rises into the air. As time goes by, the hot air balloon slowly flies to a height of dozens of meters.

At this height, hot air balloons are not very safe, but they are enough to make most ferocious beasts sigh.

Therefore, Yushan started the blower on the side and manually drove a jet, spraying out a stream of airflow, and the promoter's hot air balloon began to move.

As for the control direction, it is even simpler. The control direction of the hot air balloon depends on the sandbag on the hanging basket. Use different positions of the sandbag to control the balance of the balloon. For example, if it is hung to the left, the center of gravity of the balloon is on the left, and the overall tilts to the left, move to the left according to the principle of centrifugal force. If it is almost down, heat and rise, and then adjust the direction.

Yu Shan only experimented a few times and figured out how to control the hot air balloon.

After staying in the secret realm of the East Wilderness for a few days, Yushan had never encountered strong winds. Therefore, the hot air balloon flew in the air quite smoothly, and in just a while, it flew out for hundreds of meters.

The small valley where Yushan is located is only about one thousand meters away from the giant camphor tree. It is blocked by grass. Every time he walks below, Yushan is worried, but with the hot air balloon, Yushan flies in the air and has a wide view. With a straight line, the distance between the two places is nothing.

"Is this a big grasshopper?" Looking at the things flying over at low altitude, it looked like an enlarged version of the grasshopper, but this grasshopper was a bit big, half a meter long.

"It goes without saying that this is a mantis! But such a big mantis, its pair of knife arms can definitely chop people into two pieces!"

There are not many other animals flying in the grass, and each of these animals has its own characteristics.

I won’t talk about monsters like a car. Now even mantis and locusts have seen them. They all have one common feature, which is their enormousization.

Think about it, even spiders the size of beans have grown to a few meters tall, and grasshoppers half a meter long should be considered normal, right?

Looking at the strange insects and recording their characteristics, Yushan flew to the entrance of the small valley in just three minutes.

At this time, night fell, and some small animals began to appear at the entrance of the valley. Seeing this situation, Yushan discovered that it seemed that more and more animals in these two valleys had been around in the past few days.

I don’t know if Yu Shan’s feeling was wrong. Yu Shan felt that these few times he came out, there were more ferocious beasts than the last time he found.

"I just happened to have no food to come here, so I'll hunt a small animal."

Yu Shan closed the propulsion system of the hot air balloon and hovered the hot air balloon over the entrance of the valley to prepare for hunting.

"What is this? A cat?" Yu Shan was a little surprised as an animal like a black cat ran past underneath. There were still normal animals here?

"Catch a mouse?" Just as he saw this black cat, Yu Shan discovered that it was a black cat preying on it.

The black cat snatched a mouse with a whoosh. At this time, five or six mice jumped in a series of whizzing in the grass beside the mouse. This was a group of jumping mice.

Originally, a black cat in Yushan had finished hunting and should have finished the work. Unexpectedly, as the five or six jumping mice jumped up, five or six black shadows jumped out of the surrounding grass again.

"So many black cats? They are all collective cooperation!"

Looking at the black cat jumping five or six meters high and directly intercepting the jumping rats in the air, Yu Shan felt something was wrong. He hurriedly added firewood to make the hot air balloon rise higher.

The hot air balloon is raised, the sling is lowered, and the height of the hanging basket has not changed, but it is still twenty meters away from the ground.

This height is low in danger and is convenient for mountain hunting.

After Yu Shan adjusted the hot air balloon, he took out a pair of night vision goggles from his backpack. Only then did he take out the compound bow and prepare to practice archery skills.

Yu Shan had just adjusted his bow and arrow and was about to look for prey when he heard a buzz coming from a distance.

Yu Shan looked at the West in confusion. The sound came from there, not like thunder, but like firecrackers.

The loud noise came, and the entrance of the valley immediately became quiet. All the small animals that were coming and going crawled into the grass and stopped moving.

Boom! Another loud bang came. This time Yu Shan listened and felt that he was getting closer.

Immediately afterwards, rumbling sounds continued to come, and the intensity was as close as the guns and cannons during the war.

Yu Shan pulled the hanging basket to a height of more than 50 meters in the air, and looked into the distance, and could not see anything.

"Did someone pull the cannon in?" Yu Shan thought for a while, and finally stepped on the pedal under his feet, urged the fan, controlled the hot air balloon, and flew in the direction of the loud noise.

No matter what the sound is, as long as it is not natural, it is artificial, which means there is someone there.

Listening to the loud noise, there must be a lot of people. Yu Shan once saw so many people entering the secret realm of the East Wilderness, but he was the only one around him, but none of the others saw it. This was obviously abnormal.

Today, when he heard the sound of cannons, Yu Shan naturally wanted to go over and find out. Maybe he could still use those people. After all, it was too inconvenient to hunt here alone.

The speed of flying in the air is much faster than running below. In just over ten minutes, Yushan came to a grassland.

Yushan looked at the grassland. The grassland was normal. Like the grassland on the earth, the height of the grass was only thirty or forty centimeters high at most, unlike not far away where there were grasslands more than two meters everywhere.

After entering the grassland, the sound was heard more clearly, and Yushan could see fire lights.

"It's not like a shelling, is it a pistol?" Yu Shan saw flames constantly ejecting from a distance, and no matter how he looked, it looked like the muzzle after firing.

"What kind of guns are so loud? Isn't it asking for death if it makes such a loud noise here?"

Yu Shan once again controlled the hot air balloon to climb upwards. After climbing to more than 200 meters, Yu Shan carefully approached the source of the sound.

It was not far from that place. It took only two minutes before Yushan arrived above the battlefield.
