Standing at the mouth of the passage and looking down, it was pitch black below, deep and bottomless, like a monster mouth that chose people to devour, the mouth of the passage was not large, and the first step of the stairs was winding towards the unknown depths.

After Xiao Ran and the two came to the entrance of the passage, a musty smell instantly came up from below, obviously, no one had opened this passage for a long time.

After glancing at Tianlao, the corners of Xiao Ran's mouth turned up slightly, he finally had a clue, and took an oil lamp from a person next to him, Xiao Ran walked down first, and Xiao Huang also lay quietly on Xiao Ran's body without the slightest sound.

This is a first-order black passage, on both sides of the passage, completely made of marble, the passage is two people high and one wide, people walk below without any problems, on both sides of the passage can be seen that many oil lamps are placed on it, but all of them have been extinguished.

As the two of them continued to walk forward, the stairs continued to wind down, although they couldn't clearly feel how many meters they had descended, but at least nearly 100 meters were still there, and the damp atmosphere was stronger.

Suddenly, the staircase that had been going down suddenly disappeared, replaced by a flat road, and at the end, a bend suddenly appeared in front of them, and the two paused slightly, and after making sure that there was indeed no danger, they turned and walked towards the bend.

As soon as they turned the corner, the eyes of the two of them suddenly lit up, and a very empty huge karst cave appeared in front of the two of them, and countless bright lights were also imprinted in front of the eyes of the two in an instant.

"This is the Crystal of Earth! My God, it's still so much!" When he saw everything in front of him, Tianlao suddenly let out an exclamation, with indescribable surprise and shock in his voice.

Obviously, Xiao Ran was also shocked by the scenery in front of him.

At this moment, it appeared in front of the eyes of the two people, it was a huge karst cave with a range of dozens of zhang, the cave was oval and the height was more than ten meters, and the stalactites were standing upside down, constantly dripping with drops of clear water, and beside it, a pool of pond water was constantly rippling.

However, Xiao Ran and the others' eyes were not on this, but stared at the wall in front of the two of them in a daze, on that wall, a large area of yellow, crystal-like things were inlaid on the wall, and on the wall next to it, there were many, roughly looking, there were probably no less than nearly 10,000 pieces, and the entire cave was illuminated because of them.

"Why are there so many Tuxuan crystals?" Xiao Ran frowned, in his previous life, there were no rumors about Tuxuan crystals, why are there so many Tuxuan crystals here now, just an accident?

The value of the crystal of Tuxuan, Xiao Ran even knows more than the elders, the crystal of Tuxuan, which contains the pure aura of heaven and earth, although it is said to be pure, but most of them still belong to the earth surname, but because of its single surname, any person with a surname can absorb it without the slightest side effect.

A piece of Tuxuan Crystal is enough to make a person at the level of a swordsman be promoted to a senior swordsman above the sixth level of a swordsman, which shows its precious surname, and the crystal of Tuxuan is not only for people to cultivate, but also in the entire Wolong Empire, there are not many places where Tuxuan's crystal can be produced, and now there are so many suddenly produced in the underground of the Xiao family, if it is passed out, I am afraid that the entire Xiao family will be destroyed in an instant.

It was also after seeing these Tuxuan crystals that Xiao Ran finally understood why the Wang family in the previous life would rather hibernate for twenty years than destroy their own family, these Tuxuan crystals, if they were really pulled out, would be worth at least millions, and if they were used to cultivate their own juniors, Xiao Ran would feel terrible when he thought about it.

"Xiao Ran, you, you wouldn't have known that there were so many Tuxuan crystals here, did you? Call me here, that's what you're here to carry these things?" or Tian Lao came back to his senses first, swallowed a mouthful of spit with difficulty, and said to Xiao Ran.

Hearing Tian Lao's words, the corners of Xiao Ran's mouth twitched suddenly, and he suddenly replied: "It's the first time I've come, how do I know so much, but since there are so many, let's take a little and keep it for backup, and leave the rest for the younger generations of the Xiao family to use, Tian Lao, don't you mind?" Xiao Ran thought about it and said apologetically to Tian Lao.

"Haha, how is it possible, even if you don't give me a piece, what can I do? After all, this is a product of your Xiao family's underground, I don't have any right to ask for it, besides, you are my young master, am I afraid that you won't give me some cultivation in the future?" Tian Lao said with a smile, without the slightest look of mind in his eyes.

Indeed, he is also very open-minded, these were not his in the first place, not to mention that Xiao Ran asked him to take it himself, even if Xiao Ran didn't let him take it, he couldn't have complaints.

Now that it has been decided, Xiao Ran is no longer polite, and immediately walked directly towards a wall, and then began to dig down quickly, and the crystals of Tu Xuan dug down were directly included in the space ring by Xiao Ran.

This space ring was originally intended to be used by his father, but his father didn't want it, so Xiao Ran had to keep it for himself, but the good things in the ring, Xiao Ran gave them to his father, and now this space ring is completely empty, and there is nothing to hold tens of thousands of Tuxuan crystals.

When Xiao Ran dug up the Earth Crystal, the Elder next to him was not polite, he flew directly into the air, took out a long sword and swept it on the wall a few times, and those hard Earthen Crystals were swept down by Elder Tian with strong force, and then included in his space ring without skull ornamentation.

Xiao Ran next to him couldn't say anything with envy, just digging hard, suddenly, Xiao Huang, who had not moved, suddenly flew up from Xiao Ran's shoulder, came directly to Xiao Ran, took a piece of Tuxuan Crystal that Xiao Ran was holding in his hand and swallowed it in his mouth, and then flew back in Xiao Ran's stunned eyes.

At the same time, Xiao Huang's voice also sounded: "Brother Xiao Ran, people want to advance, this thing is of great use to Xiao Huang, so, so" At the end of the sentence, the little girl was embarrassed to continue.

Xiao Ran was stunned for a moment, then didn't say anything anymore, but smiled slightly, and then began to mine, and the old man on the side had stopped collecting the Tuxuan Crystal at this moment and stood behind Xiao Ran.

After seeing that Tianlao stopped, Xiao Ran just smiled politely, but he didn't stop at all, nonsense, now as long as Xiao Ran is about being able to improve his cultivation, Xiao Ran will definitely not let it go, not to mention this Tuxuan Crystal that has no side effects? If it weren't for the younger generations of the family, Xiao Ran would like to take it all himself.

After collecting it again for a while, after collecting about hundreds of yuan, Xiao Ran stopped contentedly, looked at Tianlao and smiled embarrassedly, and then Xiao Ran's face became serious again.

At this moment, even if Xiao Ran and the two of them each received hundreds of Tuxuan crystals, the wall did not seem to decrease in the slightest at first glance, so that Xiao Ran had to sigh again about the storage capacity of Tuxuan crystals inside, but after receiving these, Xiao Ran once again faced a problem, Xuanbing Sword, where is it above?

When Xiao Ran was collecting the Earth Crystal just now, he was not idle, his spiritual power continued to search, and even probed into the distance of three feet deep on the wall, but he didn't find the slightest thing, and he couldn't help frowning again.

ps: Ask for a recommendation and a collection, and the first one will be sent!
