Lin Yun has been swimming towards the front, the further down, the colder the water in this pool becomes, and after swimming for ten minutes, he found that there was a black stone gate on the stone wall beside the pool, which was already covered with water plants, and Lin Yun swam towards the stone gate.

The stone gate is closed, and there is another space inside, even if ordinary people find this stone gate here, they can't get in, but Lin Yun won't think about it so much, he directly and violently solves the problem, and after several palms, he finally cracked the stone gate weighing nearly a thousand catties and swam inside.

The inside was filled with pool water, and a long passage appeared in front of him, but it was not paved with stone slabs, but an ordinary dirt passage, and the space in the passage was quite large, dug ten meters high, ten meters wide, all the way to the dark inside, and in this mountain it extended in all directions, it seemed to be a labyrinth.

But these can't stop Lin Yun from moving forward, he continued to swim forward, swimming for about a few minutes, only at this moment, the corner in front of a sudden green light flashed, a long tail, the whole body of the green strange fish suddenly appeared, towards him is to bite over, look at its size This strange fish is also huge, the width is at least one meter wide, the length is three or four meters long, Lin Yun has already defended, when the strange fish opened its mouth full of fangs and bit down, its body flashed, and it also avoided the attack of this green strange fish, but he didn't expect that this kind of creature still grows in this place。

But immediately in front of it, dozens of such strange fish gushed out, and the number of them was obviously more than these, and the bottom of this pool was huge, so that these strange fish lived in it like fish in water.

The dense strange fish blocked Lin Yun's direction, and it seemed that he would not be allowed to enter this world, but Lin Yun was not so easy to get along with, in his previous life, he was known as a treasure expert, where there was a treasure, where there was a figure, how could this little strange fish stop him?

Thinking about it, the stars in Lin Yun's hands surged, and he went straight towards the strange fish, only to see that his whole body was wrapped in the stars, "Bang!" kicked the strange fish that bit it back to the place, and exploded in the fish, this time, all the fish rioted, and they came towards Lin Yun in groups.

Lin Yun smashed the two monsters in the passage in an instant with one palm on the left and right, and the other fish saw that he had killed his companion, and they even widened a pair of fish eyes and rushed towards Lin Yun, but this kind of fish to deal with ordinary people, but to die one by one, to die two to a pair, with a strange force, and the skin is rough and thick, it is estimated that it is useless to shoot bullets in the water, but they met Lin Yun, and they directly smashed several of them with one palm, which made the fish even more crazy, and more and more strange fish gathered here to swallow Lin Yun alive.

Lin Yun frowned, there were a lot of fish in this school, and he didn't do a trapped beast fight at the moment, he opened a piece of flesh and blood in the school of fish, and went towards the passage inside.

This passage is indeed a labyrinth-like maze, Lin Yun used his divine sense to explore all the way, and after a while, he swam to a stone gate, the stone gate is ajar, and there is a cave inside, and there are a few strange fish swimming in it, after Lin Yun entered the stone gate, he slapped his palm on the stone gate, and directly shook down the stone gate of nearly a thousand catties, blocking the strange fish outside, and cleaning up the strange fish inside, which eased his mind.

This cave is quite big, about a hundred square meters, there is a hall in the middle, and there are four stone rooms next to it, there should be some cultivators who practiced here, but they are dead, or they have to become immortals, Lin Yun does not know, the entire cave is empty, and no bones or anything like this have been found, it seems that the owner here has at least died here.

The four stone rooms are the living room, the alchemy room, the enlightenment room, and a utility room, but this place has already been filled with pond water, and the things inside have basically been eroded by the pond water, and have become very simple, and there are no valuable things to see, all of which are some stone tables, stone benches, stone beds, etc., and the only thing that has a little style is an alchemy furnace in the alchemy room, which is almost eroded.

Lin Yun swept it through it with his divine sense, disappointed, thinking that he could find some treasure, but it turned out to be a hole with nothing.

However, just when he was about to return the same way, in the utility room, a bulge on the ground also caught his attention, not very conspicuous, ordinary people will only treat it as a stone bump, it is difficult to find, Lin Yunyou went forward, grabbed the bulge, and pulled it up hard, a stone box more than one meter long was pulled up by him, when he swept it with his divine sense just now, he didn't pay attention to it, there was such a thing hidden on the ground.

Lin Yun called the stone box and saw that it was a cyan sword, with a lot of patterns printed on the scabbard, and the whole shape looked simple and heavy, and it was a good sword.

Lin Yun "banged", pulled out the sword body, the whole sword body shook slightly in the water, there was no rust, in the pool of water emitted a faint cold light, shocking, on its handle inlaid with a golden round stone, exuding a faint golden fluorescence, this sword is actually a very good high-grade magic weapon.

No wonder the owner here treats it as a treasure and buries it under the ground, but Lin Yun just glanced at the sword, and then didn't stop, what really made his eyes a little straight was the golden round stone the size of a child's fist set on the hilt of the sword, it was this round stone that made his face show joy, this is the real treasure, this round stone that is used as an ornament, is actually a star gold, with Lin Yun's eyesight, this pure golden star gold is definitely an extremely rare material in the universe, the biggest feature is that it can be collected into the dantian, slowly warmed by the qi of the dantian, and then use the natal fire to refine a natal flying sword, killing people thousands of miles away.

This discovery made Lin Yun indeed a little happy, and directly buckled the star gold from the hilt of the sword, today's harvest is not small, and he casually threw the cyan magic weapon sword back to its original place, Lin Yun was satisfied, his body swam, and he swam back towards the pool.

In the afternoon, Lin Yun took out the star gold, how could this ordinary person recognize such a treasure, only decorated it on a magic weapon long sword, but he didn't know that this thing was an excellent material for making sword weapons, as long as they didn't know the essentials, although they felt that this golden ball might be extraordinary, but they didn't know how to use it.

Lin Yun wrapped this star gold with Xingyuan, suspended it on his chest, and then used his divine sense to probe into this star gold, and branded his life mark on it, and suddenly this fist-sized golden ball trembled several times as if it had life.

"Close!"

Lin Yun let out a low sigh, the star gold was a flash of starlight, submerged into Lin Yun's body, and stopped in Lin Yun's sea of stars, as if it was a star in this sea of stars, Lin Yun used Xingyuan to continuously nourish his spirituality, and then used Xinghuo to continuously temper his outer body, and when the sword was completed, his first natal flying sword was also practiced.

However, if you want to completely refine this star gold into a spiritual flying sword, it will take some time, if you can enter the innate nature, it is not very difficult, but if you can refine it successfully, in the future, under his warm cultivation, you will continue to transform into spiritual sense, spiritual thoughts, and even condense the real sword spirit, it is not a problem.
