The surrounding immortal aura is very strong, Zhao Yu is like being in the immortal aura of the vast ocean, and suddenly feels as if he is bathed in a sea of immortal qi, which is extremely comfortable.

"What kind of place is this?" Zhao Yu muttered to himself with a look of surprise on his face.

He soon found that the nearby plants and trees were all immortal medicines, colorful and varied, exuding wisps of immortal energy, majestic and vigorous, as if they were spiritual.

After a while, Zhao Yu tried to cast the Void Realm Artistic Conception, and he was immediately pleasantly surprised to find that his Void Realm Artistic Conception could be explored thousands of miles away here.

Suddenly, he noticed that a giant serpent like a mountain was swimming in his direction, and his face suddenly changed greatly, and he immediately turned into an afterimage and fled into the distance.

Although the giant snake couldn't fly, it swam faster than Zhao Yu's full strength, fortunately, he used the Void Realm Artistic Conception to find the giant snake in time, otherwise he would soon be caught up by it.

Zhao Yu urged a chaotic immortal qi in his body with all his might, and suddenly the immortal power in his body gushed out, and his flying speed skyrocketed by five or six times, but he still couldn't get rid of the giant snake's pursuit.

He flew away for hundreds of thousands of miles in a row, and the ancient trees in front of him gradually thinned, and a large grassland faintly appeared.

The giant snake swam faster on the grass, and gradually got closer and closer to Zhao Yu.

Half an hour later, a large wasteland appeared in front of him, and the immortal qi there suddenly became very thin, causing the speed of the giant snake to slow down suddenly.

It didn't take long for the serpent to stop. It seems to need to devour large amounts of rich immortal qi on a regular basis in order to maintain its incredible speed and strength.

But Zhao Yu still flew away at great speed, like a streamer across the void, and soon escaped without a trace, and finally shook off the giant snake.

He flew away, and everywhere he went, the land beneath him was black and endless, with barely a single plant or tree to be seen, and no water source to be seen, so empty and silent.

Half a month later, Zhao Yu didn't know how many thousands of miles he had flown away, but he still didn't see a single plant or tree.

He knew that the most important thing now was to improve his realm strength, and he had to do everything he could to concentrate on cultivation.

Although there is almost no heaven and earth immortal qi here, there are a few low-grade chaos immortal crystals on his body, and as long as he refines a little of them, he can fill the immortal power in his body.

A few days later, Zhao Yu found a large desolate stone mountain, and he immediately flew down into a stone mountain, where he immediately opened a cave.

Zhao Yu rested in the cave for half an hour, and then concentrated on cultivating.

There were a few low-grade Chaos Immortal Crystals beside him, they were brilliant and dazzling, illuminating the interior of the cave.

Together, these Chaos Immortal Crystals were three taels, which was a huge fortune that could help him improve his cultivation.

Zhao Yu's cultivation was already very close to the peak realm of the Great Power Realm, so he had to seize the time to break through.

In the following days, the immortal energy in the cave was dense, and Zhao Yu's body was full of vitality, with many visions, and the fluctuation of immortal power was very strong.

Half a month later, the brilliance in the cave gradually faded, and the immortal qi became very thin, but the life essence in Zhao Yu's body was pervasive, and the immortal power fluctuated like sea water.

His bones and flesh underwent a massive mutation, becoming stronger.

At this time, Zhao Yu's entire body was almost dust-free, like a new life, and this transformation lasted for several days before it finally ended.

This time, he was reborn again, his physical body was several times stronger, and even the Yuan Shen and the immortal power in his body had increased many times.

However, this time, he refined all the three taels of Chaos Immortal Crystals, leaving nothing behind.

In this land where the immortal qi is extremely thin, it is difficult to survive for a long time without the Chaos Immortal Crystal.

"I'm going to go find the Chaos Immortal Crystal immediately, or I might not be able to sustain it for a month. Zhao Yu walked out of the cave and said secretly in his heart.

He had to look for the Chaos Immortal Crystal, at this moment his body was like a bottomless pit, and he needed to refine a lot of Chaos Immortal Crystals in order to improve his cultivation realm.

Now, Zhao Yu was very envious of those disciples of the Gu Immortal King family, not only did they have the most powerful cultivation immortal technique, but they also had endless heavenly and earthly treasures, and they only needed to concentrate on hard cultivation.

He had seen from ancient books that the Heavenly Realm's Gu Immortal King family possessed some Chaos Immortal Crystal Mine, and they provided enough Chaos Immortal Crystals for their disciples to cultivate and break through.

And he not only had to think of ways to get the cultivation immortal technique, but also went to the mines to find the Chaos Immortal Crystal.

Thundered!

Not only did Zhao Yu swing the blood-colored immortal sword to slash the earth, looking for the Chaos Immortal Crystal Vein, everywhere he went, the earth was full of big cracks, and there were crumbling earth and stones everywhere.

Half a month later, Zhao Yu was lucky enough to find a Chaos Immortal Crystal Vein, but it was a low-grade Chaos Immortal Crystal Vein, and it took him a day to collect half a tael of Chaos Immortal Crystals, which was too little.

Chaos Immortal Crystals are almost all hidden in the Chaos Stone, but there are very few Chaos Immortal Crystals contained in the low-grade Chaos Immortal Crystal.

In this land, the Chaos Immortal Crystal Veins controlled by the Gu Immortal King Family were the best, relatively speaking, there were very few Chaos Immortal Crystal Veins in other places, and the quality was very poor.

A few days later, Zhao Yu approached a large stone mountain again. At this time, he suddenly found a group of people, there were more than a dozen people, except for an old man, the rest were young and middle-aged, and they were looking around a stone mountain.

"Alas, the Song bandits have been too rampant over the years, if we can't hand over three taels of Chaos Immortal Crystals, we will destroy our stone village. ”

"Our strength is too weak, the strongest is only the quasi-great power realm, how can we fight against them, they are a group of very powerful bandits. ”

"There are only three days left before the deadline, and if we can't find the Chaos Immortal Crystal, then our village is really in danger. ”

The dozen or so young men whispered.

"Third Master Liu, you have circled around this stone mountain several times, are there any Chaos Immortal Crystals here?" Suddenly, a burly young man looked at the old man and asked.

"There must be Chaos Immortal Crystals in this stone mountain, and it must be a bonanza. It's a pity that this is a thousand-foot high stone mountain, and it is difficult to break through it with our strength. The old man with white eyebrows suddenly sighed and said.

"Let's go, let's go look elsewhere. Those places where the Chaos Immortal Crystals are harvested all the year round are almost all lighted, and it seems that we can only go farther away, and I don't know if we can make it in time. After a pause, Liu Sanye looked into the distance and said.

Boom, boom, boom!

When the dozen or so people had just turned their horses' heads and were about to rush into the distance, suddenly Zhao Yu suddenly appeared, he waved the blood-colored fairy sword, and slashed the stone mountain one after another.

The mountain stone continued to crack, and Zhao Yu quickly slashed the stone mountain out of dozens of huge cracks with a swing of his sword, and at this time, a chaotic immortal crystal vein suddenly appeared.

Soon after, he immediately started digging, and after half a cup of tea, he dug out one or two Chaos Immortal Crystals, and it seemed that this Chaos Immortal Crystal Vein was indeed a bonanza.
