Putting away the excitement in his heart, Lu Yan walked towards the entrance without hurrying. The closer he got to the entrance, the more he found himself unable to calm down, curious, excited, and apprehensive, not knowing what he was going to see next.

"Da... Da.."

When Lu Yan had already stepped on the steps with one foot, he seemed to think of something in his heart, and immediately turned around to look at the bear demon in the depression.

The bear demon also discovered that a secret door suddenly opened on the stone bed just now, and his eyes were full of shock and incredulity, he himself has lived here for a long time, and he has never found this secret door, but he didn't expect this human to find out not long after he came. The bear demon's face was full of chagrin and helplessness at this time, who called that human stronger than himself.

However, when it found that Lu Yan turned around, it hurriedly lay on the depression quickly, not daring to peek at Lu Yan, because it was really frightened by Lu Yan's fierce eyes just now, for fear that the little life it had finally picked up would be killed by this bastard.

"Don't pretend, I know you've been peeking just now," Lu Yan's reaction to the bear demon was both angry and funny, but he still said indifferently.

"Whew,"

When he heard Lu Yan's indifferent voice, the bear demon couldn't help but shiver in his heart, and then got up from the ground, baring his teeth and letting out a scream like a flattering one.

"Hehe....." The demon bear's reaction made Lu Yan couldn't help laughing.

"Okay, I know you can understand what I'm saying, so what I'm going to tell you next is that you have to do it honestly! or don't blame me for being merciless," he said, shaking his short sword slightly.

"Roar... Roar...."

The demon bear peeked at the glittering dagger slightly, nodded hurriedly, and let out a low roar in his throat.

"Well, that's good," Lu Yan was very satisfied with the performance of the bear demon and nodded in praise.

"Wait for me to go in, before I come out, you will stay here and not disturb anyone coming in," Lu Yan said, pointing to the secret passage behind him.

"Roar.. Roar...."The bear demon nodded reluctantly.

After explaining all this, Lu Yan turned around and moved towards the dark passage.

Along the steps downward, Lu Yan soon came to the bottom of the dark passage.

Standing next to the stone steps, Lu Yancai sent down that all around was dark, even with his strength as a Qi Realm martial artist, he could only see that he could see about five or six meters around, and the surroundings were all black and misty, and he couldn't see his five fingers when he reached out, and he couldn't see anything clearly.

It was as if I was in a dark world, with a strong musty smell everywhere and thin air. The Tianyan True Qi in his body moved slightly, and he waved his hand to shoot out one after another True Qi, which was able to dispel those musty smells a little, but the surroundings were still as dark as ever.

"I knew I would have brought the fire fold when I came out," Lu Yan muttered a few words, regretting that he didn't remember to bring the fire fold when he came out this morning, otherwise he would have been able to use the light of the fire fold to investigate the surroundings.

However, Lu Yan muttered twice and quickly regained his composure. Relying on his eyesight, which can still see a radius of five or six meters, he cautiously groped around.

He wanted to find out if there were any traps or torches here, after all, this place was dug by hand, so it was impossible for the people who had done this secret tunnel before not to think about the problem of lighting.

Soon, Lu Yan touched a side of the wall, and as soon as his hand touched it, he only felt that the tentacle was wet and smooth. Ignoring the wet hands, Lu Yan quickly groped up and down, back and forth, because this place was too quiet and too dark, and staying for a long time would gradually make people feel uneasy.

Time passed minute by minute, and Lu Yan didn't know how many meters he had walked forward, maybe tens of meters, maybe just a few meters, because he was so focused on finding the mechanism just now that he forgot about it.

"Smack...".

Immediately after that, there was a sudden light in the dark tunnel. The sudden light made Lu Yan's eyes shrink sharply.

After feeling accustomed to the light, Lu Yan slowly opened his eyes, and then began to slowly look at everything around him. And his hand was pressing on a round raised stone at this time, and when Lu Yan touched this bulge just now, he pressed it gently, and the surroundings suddenly lit up.

Sure enough, there was a mechanism for lighting, Lu Yan smiled indifferently.

When everything around suddenly became clear, everything around him was clear in Lu Yan's eyes. I saw that the road is arched in the shape of an arc, and the walls on both sides are made of square stone bricks, the surface is dark gray, and some bricks are still stained with water stains on the surface, and there is a thin layer of green moss on it. The floor is paved with bluestone bricks and extends to the depths. On the top of the road, there are night pearls the size of pigeon eggs, and it is the light emitted by these night pearls that illuminates the surroundings.

"Hey, it's so extravagant," Lu Yan took a deep breath and slammed his lips in exclamation.

It seems that the people who built this place before must have been either rich or expensive, otherwise how could they use so many night pearls to make lighting things.

You must know that even as one of the four major families in Longzhou Mansion, the Lu family, which has been inherited for thousands of years, cannot do such a luxury. It's not that Lu Yan underestimates the Lu family, but these night pearls themselves are very precious, and with his understanding, each of these night pearls in Longzhou Mansion is worth at least a thousand gold, not to mention that there are so many of them here.

"Rich.... I have made a fortune......" Lu Yan felt a burst of joy in his heart.

However, Lu Yan was not excited for too long, after all, he had just come in this road, and he had not been far away, and he had not yet understood what the situation was in front of him. So he drew his dagger from his waist, concentrated on keeping himself awake at all times, and began to walk along the corridor towards it.

Along the way, Lu Yan did not encounter any danger, and after walking for nearly a cup of tea, the field of vision in front of him suddenly became extremely broad, and at the end of about ten meters in front of him was a stone gate closed on both sides. Lu Yan quickly walked to the stone door in two steps as three steps, and then stretched out his hand and pushed hard, with a creak, his eyes suddenly opened up, and there was a huge space secret room. This should be the end of the corridor, no longer a narrow corridor, but a huge circular space. Lu Yan roughly estimated that this secret room was about a thousand square meters in area.

"I'll .........." Just glanced at it, Lu Yan couldn't help but roar.

He was completely shocked by the scene in front of him, his pupils were dilated, his eyes flashed with astonishment, and the whole person was instantly stunned.

I saw that this huge circular space secret room was full of all kinds of things, there were countless metal boxes, rows of bookshelves, and thousands of strange swords piled together like a hill.

"Wow..... Got rich... I've made a fortune...."Lu Yan exclaimed excitedly

Lu Yan put away the short sword in his hand, and then walked to the nearest box.

After walking in, Lu Yan saw that these boxes were all made of raw iron, and a layer of greenish-brown patina had appeared on the surface of the copper locks on them.

Reaching out and holding the copper lock, the aura in the body operated slightly, and with a hard pull on the hand, the copper lock broke in response to the sound. Toss the copper lock to the side and lift it gently to open the lid.

"Pop ....." Then a dazzling light came to the surface, and Lu Yan hurriedly blocked his eyes with his hand. After a while, he removed his arm.

"Spirit Stone ........." Lu Yan exclaimed in surprise, his eyes full of shock.

I saw that the box was full of small pale yellow stones, neatly stacked together, filling the entire box, and there was a thin layer of glazed halo on the surface of the small stones, exuding pure aura fluctuations.

This was also the first time Lu Yan had seen the spirit stone so really, and he had only seen and written it in the classics of the family's library before.

Lu Yan hurriedly opened several boxes in a row with the same square, and all of them contained the same spirit stones.

As the name suggests, "spirit stone" is a stone containing the aura of heaven and earth, these stones are formed by the aura of heaven and earth under special circumstances, because it is naturally formed, so the aura contained in it is very pure.

The cultivation of a martial artist is actually to absorb the aura between heaven and earth to refine himself, and the more he absorbs, the more refined he is, the stronger his own strength will be.
