A quarter of an hour later, Xu Wu lay on the ground, beaten to death by Chu Yunfeng.

"I told you a long time ago, I launched a surge, and the consequences are very serious, but you don't listen!"

Chu Yunfeng clapped his palms and muttered to himself.

"Alas... Next time I see Mingyi, I don't know how to explain it to him..."

To this day, I still think that Ming Yi is his friend, and he has always been thinking about visiting his house for the third time.

Perhaps he was sorry, Chu Yunfeng found a place at random, buried Xu Wu's body, and set up a tablet, with the inscription "The Tomb of Prince Xu Wu", and the inscription "Lin Yushan never killed".

After finishing the incident, he suddenly remembered that the storage ring had not been taken off, and it took a lot of effort to dig out the corpse, and he happily put the storage ring in his pocket.

"The deceased is great, Xu Gongzi, offended! May you go all the way on the Huangquan Road!"

Chu Yunfeng respectfully bowed to the corpse three times, and then buried it alive.

After the wind blew, the cave was in a mess, and only Chu Yunfeng was left alive.

After a day of cultivation, Chu Yunfeng recovered intact and began to carefully explore the wind tunnel.

He wanted to see what kind of power could block a lethal Gang wind in the water droplets, and it could not dissipate for a long time.

Walking in a wind tunnel is like walking in the belly of a mountain.

An hour later, I finally saw something alive, a shady coral-like plant that grew in clusters on the rock wall.

Chu Yunfeng approached the rock wall, opened it and took a look, only to find that there were water droplets on the rock wall, it turned out that this plant grew towards the water.

It's also strange to say, this is the Elephant King Wind Cave, Gangfeng should be commonplace, how did these things survive?

They grow in clusters and have an extremely smooth surface that protects them from wind.

But Gangfeng is not an ordinary wind, the destructive power is extremely strong, even the monks in the early stage of Gangqi were torn apart in an instant, how could they be! However, the fact is that these shady plants are not only intact under Gangfeng, but they also look like they have been growing for some years.

On the rock wall, due to years of weathering and water erosion, traces have been formed, and at first glance, it looks like rows of ribs, and from the outside to the inside, the space is getting bigger and bigger. Surprisingly, no matter where the water droplets hang on the top of the rock, they don't fall easily.

From a distance, it's easy to assume that the water droplets are seeping down from the top of the rock. Actually, it wasn't, but it spread from the depths of the wind tunnel.

After going deeper into the three miles, the wind became a little stronger, and Chu Yunfeng slowed down, thinking that he should be close to the bottom of the cave. The further he went, the stronger the wind speed, until he could barely resist it with ninety percent of his physical strength, the front suddenly opened up, and the first thing that caught his eye was a stone spring.

In the layers of granite, the spring water is constantly tumbling, and the whole area is filled with mist, which was formed by the condensation of the water droplets that touched the rock wall.

In front of the side, about 100 meters away, there is an air outlet, from which a steady stream of wind blows, which should lead to the deepest part of the wind tunnel. After the wind came out of the tuyere, it was blocked by the mist, and its power decreased sharply after passing through. Even so, it was not something that ordinary Gang Qi Realm early stage cultivators could bear.

Chu Yunfeng cautiously walked to the top of the granite and stood on the edge of the stone spring, only to find that there was a pale golden ivory at the bottom of the spring. The wind passes through the mist, and the energy consumed is finally absorbed by the ivory. When the tusks absorb the energy, they release a trace of an unknown object that evaporates into the mist with the spring water.

Chu Yunfeng speculated that some of this unidentified object would be attached to the rock wall with the condensation of steam, and some would be carried by the Gangfeng, and after the Gangfeng passed over the rock wall, it would eventually attach to the rock wall.

Unknown objects accumulate to a certain extent in a certain part of the rock wall, and after a long time and a series of changes, bubbles similar to amber will be formed, resulting in the so-called "Gang weathering" phenomenon.

It's all speculation, but there's only one thing in general – this ivory is a treasure!

After making sure that there was no danger nearby, Chu Yunfeng slowly put his hand into the water, but as soon as he touched the surface of the water, he reflexively retracted.

The water temperature is hot, to say the least, it has to be hundreds of degrees, it is not normal water at all, no wonder it keeps tumbling. It's not that Chu Yunfeng is not careful, the air is full of mist, but the temperature is not high, it is easy for people to get swayed.

Chu Yunfeng had to take out a metal stick from the storage bag, stick it into the water, and salvage the ivory after a full stick of incense. As soon as the water came out, the ivory shone golden, and the entire wind tunnel illuminated was extremely transparent.

Put the metal stick away and hold the ivory in your hand. Suddenly, the ivory turned, and the golden light shrank violently, turning into gilded ancient characters, which were refracted onto the rock wall.

Seeing the first three words, Chu Yunfeng was immediately overjoyed - "Nine Elephant Fist".

Elephant, known for its strength, this boxing method is eighty percent of the cultivation of strength. Although the "Ten Thousand Stone Heart Sutra" he cultivated also had a cultivation of strength, the focus was on physical strength and on defense.

Chu Yunfeng can exert a maximum power of fifty stones, which is almost six thousand catties. And the power of one elephant is 12,500 catties, which is equivalent to the power of a hundred stones, that is, the power of the middle stage of the Gang Qi Realm.

After memorizing "Nine Elephant Fists", the ivory also ran out of energy and turned into an ordinary piece of ivory. Since then, it has been impossible for people to come back to find the opportunity of the Gang weathering elephant.

The Nine Elephant Boxing is divided into ten layers: the first nine weights, and the power that each weight can hit is the power of one elephant and the power of two elephants... Until the power of the nine elephants, nine is the number of the poles of a single word, so the tenth is the power of all elephants.

The ivory was taken away from the bottom of the spring by Chu Yunfeng, the temperature of the spring water quickly dropped, and the mist continued to dissipate, and at the same time, the wind became stronger and stronger.

Chu Yunfeng used ten percent of his physical strength, and gradually became a little overwhelmed, and he knew that it was time to leave the wind tunnel.

"Looks like you can't go inside!"

Chu Yunfeng glanced at the tuyere, turned around and walked out of the wind tunnel.

Just one Elephant King Wind Cave was so dangerous, and the three forbidden area wind tunnels were even more difficult, Chu Yunfeng felt that his strength was seriously insufficient. So, he decided to find a secluded place, cultivate first, improve his cultivation, and then explore.

For a month, Chu Yunfeng studied the Nine Elephant Fist day and night, but he was never able to get started. He had to put it down for a while and instead practice the Shadow Plum Blossom Needle taught by Saltwater.

The Shadow Plum Blossom Needle is one of the three great skills of the Divine Thief Mei Maniac Mei Sanxiu. Listening to her name, most people may think that Mei Sanxiu is a woman, but this is not the case. Sanxiu is not his real name, but is used to describe his three stunts: Wind Dance Steps, God's Hand and Shadow Plum Blossom Needle.

In the deep valley, Chu Yunfeng picked out a stone from the stone mill beside him, and threw it out without cultivating. After a few breaths, the stone hit a leaf a hundred meters away with unmistakable accuracy.

The monk is not an ordinary person, he is deaf and clear-sighted, and this kind of kung fu is not unusual. But it's such a simple thing, he repeated the practice for half a month.

Half a month later, the stones remained the same, and the target was replaced by leaves two hundred meters away, and he still completed it easily.

Ten days later, the stones remained the same, and the target was aimed at the leaves 300 meters away, which could also be completed, but there were occasional mistakes. With his physical body alone, he was able to strike fifty stones, which was enough for his eyes.

From 300 meters away, when you look at a leaf, you can only see a shadow, and you have to be 100% hit, you have to train your eyesight. This practice took more than two months.

After there was no problem at all, the distance remained the same, Chu Yunfeng replaced the stone with gravel, and the success rate plummeted by fifty percent. Gravel is light in weight, small in size, susceptible to air resistance, and deviates from the target halfway through.

If you only consider hitting the leaves, you can increase the strength and improve the hit rate, but if you want the strength is just right, not a single point, a lot of points, just right, when the gravel is about to land, just hit the leaves, this is difficult. It is necessary not only to have a foundation of vision, but also to control the subtleties of power.

At this point, Chu Yunfeng practiced for half a year.

Next, Chu Yunfeng replaced the gravel with a silver needle, the silver needle has a small cross-sectional area, and it is extremely fast, and the moment he makes a move, he must grasp the direction and strength. It took him five days to get used to it.

Then, the silver needles and distances remain the same, and the target is changed from leaves to mosquitoes. The target volume changes from large to small, from static to static, and the difficulty increases suddenly.

It was another half a year before Chu Yunfeng successfully stabbed the mosquito three hundred meters away with a silver needle.

However, that's not all.

In the end, Chu Yunfeng blindfolded himself with a black cloth, and only relied on his hearing and feeling to lock on to the mosquitoes in the distance. This step is the longest, up to a year.

After more than two years of cultivation, the emperor paid off, and he finally mastered the Shadow Plum Blossom Needle.

At this time, he went back to practice Jiuxiang Boxing, and many of the problems he had encountered before were solved.

Originally, Chu Yunfeng was obsessed with huge strength and neglected to be flexible, making it difficult to cultivate. After the Shadow Plum Needle first started the path, it also learned to be flexible.

"The wisdom of the ancient sages is really profound!"

Chu Yunfeng sighed secretly.

Three months later, Chu Yunfeng's enlightenment began to bear fruit, reaching the first weight of the Nine Elephant Fist, and he had the power of one elephant. This strength can be regarded as the guarantee of entering the wind tunnel in the forbidden area.
