Yi Xuan called Lu Feng and gave a rough explanation, saying that he and Di Xing were going to inspect the neighborhood, seeing that the two of them had solemn faces, Lu Feng knew that something important was happening, so he didn't ask much, but told the two of them to pay attention to safety.

Yi Xuan followed the route in his memory, led Di Xing over the hill at a very fast speed, came to the edge of the grassland halfway up the mountainside, followed the direction of the fire tiger that day, walked dozens of miles, and came to a deep entrance to the Meteorite Sword Valley.

Di Xing didn't hesitate to say what he said just now, he really stood at the mouth of the valley at this moment and saw such an eerie scene, with a timid expression on his face: "Senior brother, why don't we take a look around first, this valley looks a little scary!"

Yi Xuan said with a smile: "There is no light in the spirit mine, it's not more terrifying than here, don't worry about me, it's fine." Senior Brother's Flying Sword specializes in defeating demons and evils, look at my Thunder Sword!" Yi Xuan raised his hand and released a small purple lightning, which flew in the air and grew bigger and bigger, and when it reached the mouth of the valley, it had already transformed into an electric python the thickness of a bucket, more than a few feet, and rushed towards the valley with its teeth and claws. The mist in the valley was scorched by the electric python, and there was a scorching smell in the air, Yi Xuan pointed to the valley: "Do you see it?"

Yi Xuan said it easily, but he was very vigilant in his heart, and put the most demon-suppressing thunder sword on the periphery, and the middle layer used the fire sword to form a second line of defense, and used the Xunfeng sword and Kanshui sword to protect him, firmly guarding himself and Di Xing, and going deep into the valley step by step, and using the thunder sword every hundreds of zhang to disperse the dense fog to ensure a good line of sight, because of the experience in the spirit mine, Yin Sha could not be detected in advance with spiritual sense, and he had to rely on his eyes to be vigilant.

Entering the valley mouth for nearly a mile, Yi Xuan's heart suddenly throbbed, and several thick trees around him each floated out a thick black mist like ink, and the surface was churning like boiling water, rushing towards the two of them.

Yi Xuan was distracted and dual-purpose: the electric python turned into the Thunder Sword shook its head and tail, opened its huge mouth and released countless tiny electric rays to form a power grid, enveloping the three nearby black fog in it;

The black fog wrapped in thunder and lightning came out with a crying howl like a night owl, and the black fog churned left and right and suddenly wanted to escape from the power grid, but where would Yi Xuan give Yin Xia a chance to escape, the thunder sword electric python spit out three small and exquisite purple electric snakes again, and accurately drilled into the three black fogs, and after three loud explosions like thunder, the black fog let out a sharp roar and then turned into nothing. The remaining two clouds of black mist found that the accomplice had disappeared, and without waiting for Yi Xuan's action, they quickly flew towards the depths of the valley......

Di Xing, who didn't dare to move next to him, had already been frightened by these yin demons, his face turned pale, and his lips trembled: "Master...... Elder brother...... Otherwise...... Let's not go into the valley first, and when we return to the sect, we will find some more people to explore, okay?"

Yi Xuan saw that he was really frightened, so he nodded and agreed: "Senior brother, I will protect you out of the valley first, I can visit alone, my swordsmanship is just to restrain the yin, if it is clear that there is a spiritual mine, it will not be too late to report to the sect." ”

Although Di Xing couldn't bear to let his senior brother take the risk alone, but because of the fear in his heart, he was at a loss, but it would become a drag, so he followed Yi Xuan out of the valley, and the two sides agreed that after three hours, no matter whether he found it or not, Yi Xuan had to come out of the valley, and if he didn't return on time, it meant that he was in trouble in the valley, and Di Xing immediately asked the sect for help.

Yi Xuan returned to the place where he had fought with Yin Xuan just now, and continued to move forward, without Di Xing on the side and needed to be distracted and taken care of, the speed of travel was greatly accelerated, and he could take out all the means, the wood incarnation and the earth incarnation also flashed around Yi Xuan, constantly passing on what he saw and heard to the deity. The Falling Sword Valley is a closed valley with a radius of more than ten miles, surrounded by the tall peaks of Fenyang Mountain on all sides, and there is only an opening more than ten zhang wide, with the assistance of the avatar, Yi Xuan quickly finished exploring the situation in the valley and came to a crack in front of the mountain wall.

It was a crack in the rock that was only the width of a palm, and it was pitch black and bottomless. Yi Xuan took a few steps back, and the Thunder Sword slashed heavily on the mountain above the crack, and a burst of rubble fell, and the crack expanded into a hole that could be passed sideways, and several Yin Evil slammed out from it, all of which were pierced through the heart by the Fire Sword waiting on the side, turning into green smoke.

Yi Xuan's mind turned, the Thunder Sword flew into the cave first, a purple thunderbolt instantly illuminated the cave, and the large clouds of pitch-black fog were so frightened that they hid in all directions, making a sharp whistle, and the fire sword followed closely around the entrance of the cave, and the cave wall spontaneously combusted without wind, sending out a raging fire that burned the damp and dark aura in the cave.

Yi Xuan put away the wood incarnation and slowly entered the hole, letting the earth incarnation go deep and quickly into the ground to explore if there were any traces of spirit ore. The inner edge of the cave entrance is smooth and neat, it is definitely not a natural formation, the more Yi Xuan walks, the more surprised he is in his heart, could it be that this place has already been developed?

With endless questions, Yi Xuan walked towards the depths of the earth under the guidance of the earth incarnation, and the yin evil that had escaped just now seemed to have disappeared, never appearing again, until he came to an empty underground hall.

The hall is obviously hand-hewn, and there are multiple metal columns in the center and at the four corners, but due to their age, the surface of the columns has long been rusted and mottled, and the original color cannot be seen. There are four entrances to the hall, each entrance has a stone door, the other three stone doors are all tightly closed, only the entrance stone door where Yi Xuan came in is opened from the inside, and the ground near the stone door is scattered with a few dry bones.

Yi Xuan remembered the scene when the remains in the spirit mine were possessed by the Yin Demon, cautiously approached the dry bones, and gently touched its surface with the Thunder Sword, but unexpectedly, all the dry bones turned into powder, but from one of them, a jade talisman rolled out.

Yi Xuan picked it up and looked at it with his spiritual sense, and only then did he know the origin of these dry bones: it turned out that thousands of years ago, there was a sect called Sword Washing Pavilion stationed nearby, these dry bones were all disciples of the Sword Washing Pavilion, and they were sent by the sect to guard and collect the spirit mine, but they were blocked and slaughtered in the spirit mine by one of the disciples in collusion with the monks of the hostile sect, this person engraved the encounter in the jade talisman before he died, hoping that someone could pass the news back to the Sword Washing Pavilion to avenge himself, but for some reason, the Sword Washing Pavilion did not send other monks here to investigate, and the spirit mine here seemed to be abandoned, until the arrival of Yi Xuan today。

"Wash the Sword Pavilion, this sect has never heard of it!" Yi Xuan recalled the classics he had read in the sect, but he had no impression of this sect, but there was really a genuine spiritual mine hidden in this Falling Sword Valley, which was the biggest gain of this trip.
