When approaching the canopy of the tree, Sun Yunhao probed with his divine thoughts, and after making sure that there were no other birds nearby, he sacrificed his wings, soared into the air, and looked around a few feet away from the dense forest. The sky was cloudy, and below it was a dense forest, and at the other end of the forest, there were mountains and lakes.

"There, it's 'Crystal Jade Peak'!" Someone exclaimed. Sun Yunhao's eyes froze and looked at a mountain more than 100 miles away in the east, this mountain is crystal clear throughout, forming a sharp contrast with other mountains, and it is also a landmark building in the Descending Dragon Valley.

On this mountain, there is an ore called "green crystal", and this ore is hidden in every corner of this mountain.

Hair crystal, as the name suggests, is a thin thread inside, like hair, condensed by pure spiritual power.

Generally speaking, the finer the hair, the more regular the shape, the purer and more precious the aura contained in it. It is precisely because of this that the monks divide these hedrons into two grades.

Xia Pin found that the spiritual threads inside were scattered and disorderly, and they did not have much effect.

The medium-grade hair spar is composed of spiritual threads, which are unconventional and neat, forming a circle of vortices, which can be used to refine the best magic weapons.

There is also a kind called blood crystal, which is an extremely rare top-grade blood crystal, and this top-grade blood crystal is an extremely precious refining material.

In the Valley of the Descending Dragons, exchanging for a Tsukidan is one of them.

In addition, there are only a few first-grade, second-grade, and third-grade demon beasts here, and their strength is also the appearance of the tenth layer of the Qi Refining Period, which is relatively dangerous in this Dragon Descending Valley.

Because Jingyu Peak was not too far away from him, and the danger level was relatively low, it did not contradict his original plan, so Sun Yunhao decided to go to this mountain first to see if he could find such a rare "blood essence stone".

Sun Yunhao didn't have the guts, he directly controlled the magic weapon and went straight to Jingyu Peak.

Yu Jian repeatedly told him that he could not fly the magic weapon over the valley for a long time. First of all, the sky above the Dragon Descending Valley was shrouded in an extremely powerful formation, and if it flew too high, it was very likely to touch the formation and kill people. This is an iron law forged with the lives of countless people and with blood.

Second, there are a lot of birds and monsters in the valley, and if they are targeted by them in the sky, it will be a big trouble.

The third point is that encountering other immortal cultivators in this valley is far more dangerous than those demon beasts. And in the high air, when the line of sight is not obstructed, it is easy to be detected by the nearby immortal cultivators, and thus be chased and ambushed by the other party.

Sun Yunhao flew back into the woods. He put a scale armor on his gray robe, and replaced his shoes with hundred-feathered boots. As for the black cloak, it would affect his vision, and in this valley, every time they met, it was a fight of life and death, and there was no need to hide his appearance at all, so Sun Yunhao didn't bring it with him.

Then, suddenly, a strange seal formed in his hands, and his body disappeared in place in an instant. This is a low-level "invisibility technique", a secondary spell that is very common among monks. But now, Sun Yunhao seemed to have disappeared out of thin air, and even his aura was completely hidden, if it weren't for the presence of other immortal cultivators, Sun Yunhao's existence would not be detected by his divine sense alone.

This is the "hidden spirit technique" that Sun Yunhao spent a lot of time and energy to master. To cast this kind of secret technique, you need to consume a certain amount of aura, and when you cast it, you can't use too much aura, otherwise, you will lose control of the aura, which will affect the casting of hidden spirits.

Sun Yunhao took out a cyan spirit stone with medium grade water attributes, and while performing the concealment technique, he also kept absorbing the aura in the spirit stone, recovering the aura he had consumed because of the concealment technique. In this dangerous Dragon Valley, you must have sufficient spiritual power.

And Sun Yunhao's divine thoughts spread within a radius of 100 zhang. In this way, he dared to march towards Jingyu Peak with confidence.

Sun Yunhao walked forward for more than 20 miles, then walked out of the woods and appeared by a quiet small lake. If he is not mistaken, according to the description on the jade slip, this should be a small lake called Gengxin Lake. In this lake, there lives a first-class demon beast "Spinning Turtle". This is a turtle with a bird's head, turtle body, and snake tail, and it is dark red on weekdays, which looks very weird. Although this turtle can only cast several low-level defensive spells such as "Vajra Cover" and "Stone Skin Technique", it does not pose any threat to the monks in the Qi refining period, but because it is extremely hard, it is extremely resistant to various spells, and its courage is extremely small, so it hides by the lake on weekdays, and it is difficult to be caught.

Sun Yunhao is also quite interested in this "spinning turtle", after all, in many ancient books, it has been mentioned that the carapace of turtle-like demon beasts is an excellent material for refining shield-type magic weapons. Among them, there are many high-grade and top-grade defensive magic weapons. In some ancient books, it is even recorded that the carapace of a turtle above the fifth order can be used to make defensive treasures!

Because Sun Yunhao didn't have a good defensive magic weapon, his speed slowed down when he approached the lake.

Sure enough, beside a lake a few miles away, there were seven or eight strange red turtles, lazily basking in the sun there.

This area has an open terrain and excellent views. Even if he used the concealment technique, as long as he was only a hundred feet away from this giant tortoise, he would be aware of it. And as soon as those turtles saw him, they would definitely retreat immediately. And as soon as they enter the lake, they are much faster, and it is not easy to catch them.

After thinking about it, Sun Yunhao thought of a way.

He walked cautiously through the grass, only three or four miles away from the turtles. Then a yellow "earth escape talisman" was slapped on his body, and after a flash of yellow light, Sun Yunhao's whole person disappeared into the ground.

This is a high-level spell in the Qi refining period called "Earth Escape Technique", which allows people to move underground for a short time without any hindrance, until the spiritual power in the talisman is exhausted, and they can not leave this place.

At this time, Sun Yunhao was four or five feet deep underground, and his whole person was wrapped in a round earthy yellow shield. The dirt and rocks around them disappeared in the yellow light, but in the blink of an eye, everything was back to normal. Therefore, Sun Yunhao, who was wearing yellow light, was walking on the ground as if he were walking on the ground, and was heading towards the lake where the turtle was located at an extremely fast speed.

After a while, Sun Yunhao's mind moved, and he found that he had approached the turtle, and immediately the yellow light turned, flew upward, and drilled out directly from the ground.

There were a few turtles playing by the lake, and suddenly, a figure came out of the mud, startled them, and then they got into the lake.

A talisman came out of his hand, and in a flash of yellow light, it turned into an earthy yellow light curtain several feet in size, trapping the huge whirlpool turtles inside, making it impossible for them to return to the lake.

This is the "dungeon talisman" that Sun Yunhao just threw out to imprison several huge whirling turtles. The tortoises kept crashing into the light curtain, but the light curtain didn't move. The Spinning Turtle was originally only good at defense, and its attack ability was very weak. Not to mention these whirling turtles, even if they are given seven or eight hours, they don't want to break through the light curtain of the dungeon.

Sun Yunhao took out the Yushan Seal and slowly poured a trace of aura into it, and after a while, the small seal became as big as the light curtain. Sun Yunhao hurriedly stopped the movements in his hand, and then controlled the Yushan Seal and flew towards the turtles.

These tortoises also have aura in the end, and they feel the great danger coming from their heads, and several of them make a "crackling" sound from their mouths, as if the wood has been split, and their heads, limbs, and snake tails are all retracted into the turtle shell.

With a loud "boom", Yushan Yin slammed into the tortoises, not only smashing the dungeon directly, but also slamming the feet of the tortoises into the ground four or five feet underground. It's just that after Sun Yunhao took back the jade mountain seal, he was stunned to find that the few turtles were still intact, and one of them was still trembling and getting up from the ground, ready to re-enter the lake.

With a sound of "Z", the golden light flashed, and the long sword in Sun Yunhao's hand flashed, and he cut down the still somewhat confused Xuan Turtle, cut off its head, and after struggling on the ground a few times, he could no longer move.

And the remaining Xuan Turtles, under the attack of the Yushan Seal, have been shattered to their internal organs, and they have already died.

Without saying a word, Sun Yunhao used a cloth sword to cut off the carapace of these turtles piece by piece, and then put them into his storage bag.

Then, he quickly ran to a small forest by the lake, and in a tree hollow, Sun Yunhao found a high-grade spirit stone and began to close his eyes and recuperate.

Casting the Jade Mountain Seal, the consumption is even greater than Wang Lin imagined, and with one attack, most of the mana in Wang Lin's body is immediately consumed, and he must use high-level spirit stones to recover quickly.

With the help of the top-grade spirit stone, in just an hour, he filled up the spiritual power in his body.

During this period, Sun Yunhao also used his divine sense to keep a close eye on his surroundings to ensure that if there was any abnormality, he could respond immediately.

A few hours later, Sun Yunhao finally arrived at the foot of Jingyu Peak, and it was already dusk.

Sun Yunhao raised his head and looked at the crystal clear giant peaks, as well as the crystal clear boulders of different sizes, and was a little speechless.

If he wanted to pick out a blood essence stone among these crystals, he couldn't see it at all with his divine sense, and he had to look for it one by one, which was tantamount to looking for a needle in a haystack.

Some hedrons are so smooth as a mirror that you can't step on them. Some are pointed, like sharp knives. All of this makes it more difficult to find the treasure in the crystal.

No wonder this is the safest place, but over the years, there are very few people who can get the Blood Essence Stone.
