The courtyard behind the house was overgrown with miscellaneous trees, and the rusty sword was everywhere, and there was a smell of decay. The boy covered his nose and looked around, there was nothing unusual, but the temperature was abruptly much lower, which should not be the case.

After walking a few steps further, Uncle Tie Hong pointed to a rusty iron plate on the ground and sold treasure to the young man.

"Yo, authentic?" Xu Han raised his eyebrows, sucking his saliva and looking expectant.

In fact, he is not a good drinker, and the drinks brewed by the villagers are all soaked in wild fruits in the mountains, saying that it is sake, but it is just a slightly alcoholic fruit drink, so it is not a big deal to drink more.

Brushing away the floating soil and broken leaves on the iron plate, Tie Hong bent down and overturned the iron plate. Sure enough, a dark hole was revealed under the iron plate. Xu Han looked over, and he couldn't see anything in the dim cave, but he could faintly smell the fragrance of fruit wine.

A cool breath swirled up from the cave, and the two people, who had been scorched by the scorching flames for a long time, looked sluggish by the cool breeze on their cheeks, and their spirits were suddenly lifted a little.

Xu Han looked at Uncle Tie Hong suspiciously, as if he was puzzled, the breeze was not a big deal, but the temperature in this cave was much lower than that of the outside world, and it could faintly make people feel the cold.

"Keep up, be careful......" Tie Hong didn't explain, his thick body crowded the hole to the brim, and he shrank into the ground with great effort, looking like a fat mouse, squirming and squirming for a long time before finally going down. And Xu Han also bent down and carefully followed Uncle Tie Hong into the cave.

A few feet off the ground, the boy jumped straight down the wooden steps, the room was so dark that he almost twisted his ankle. After standing still, he looked back, only to see Uncle Tie Hong's sturdy figure carefully holding on to the wall and touching it, there was a hanging object on the opposite wall, Tie Hong took out the flint from his waist, lit the torch on the wall, and dispelled the darkness of the basement.

Here is an ear room, the room is only ten steps before and after, the loess covers the ground, slightly cloudy and damp, the wall is made of bluestone slabs, but the years have passed, and it has become bleak.

The two of them lifted a curtain one after the other, and unexpectedly, behind the curtain was not a room but a long corridor. The craggy and strange rocks in the corridor are convex and concave, but there is a bit of gloom. Xu Han didn't ask, Tie Hong knew that the young man was confused, so he opened his mouth to explain,

"This place is a vein, and the ore was brought out of the hole where I came down twice, and the iron ore is not very large, and when it is cleaned, it is abandoned here and no one cares about it. A few years ago, when I came here by chance, I set up a stove above it and settled down. ”

"I don't know what's so special about this?" Xu Han was still puzzled and continued to ask.

"Heh, the left and right are just for convenience, if you talk about differences, it can be regarded as some!" Tie Hong sold a pass, signaling the young man to hurry up.

After a few more steps, Xu Han suddenly heard a strange sound, and it was clear after a little analysis.

"Underground Dark River?" Xu Han asked.

"Exactly, a few years ago, when the earth's veins moved, there was an underground water vein gushing up, and the water was a little colder than the ordinary one, and even after taking it out, its temperature could not change much in a few hours, just for quenching. The boy nodded, not speaking. The sound of rushing was getting louder and louder, and there was a faint light at the end of the road ahead. Tie Hong trotted up and beckoned Xu Han to follow.

Crossing the end of the road, the undercurrent of the water flow is quite turbulent and comes into view, the water veins gush out of the cracks in the ground on the left, and there is an open space of several zhang on the right, and then the cave gradually closes into narrow gaps, and the water veins do not know where to flow.

"This ......." Xu Han couldn't help but exhale in surprise, unexpectedly seeing the young man's surprised expression, Uncle Tie stroked his beard and smiled, "How is it?

What Tie Hong shows off is not this clear cold spring, but this several zhang long crypt. On the rock wall, every little distance, up and down are dotted with dense stones of different colors, the big stones have fists, and the small ones are only like buttons, and the large and small stones all exude a dense light!

The cold spring in the center is surging, and the rock walls on both sides of the river are dotted with starlight, which at first glance looks as moving as the Milky Way that can be seen on a summer night in the previous life!

Xu Han was fascinated by it, Tie Hong didn't care about him, he jumped down the river with a pop, the turbulent water could not shake his body, and still washed away the heat and poison of his body and mind by the cold current, and after a few comfortable moans, Tie Hong plunged into the bottom of the water, groped at the bottom of the river for a while, and dragged out two small wine jars from the gravel. When he got up, the water splashed everywhere, waking up the boy who was thrown in a daze.

"You kid has a good mouth today, I can take out all the treasures in the box for you!" said that he threw a pot with Xu Han, and Uncle Tie Hong couldn't wait to tear open the seal and drink it.

"Happy!" The spicy but cold jade dew elixir entered the throat, tearing apart the confused minds, but the soft aroma of the wine was extraordinary, making people immersed in it for a long time. "Huh, you kid was noisily drinking just now, why are you stunned now?" Seeing that Xu Han was still stunned, Tie Hong said quietly.

Xu Han pulled out a small piece of exotic stone from the rock wall and observed it carefully in his palm, this crystal transparent stone seemed to be peerless jade, exuding faint fluorescence, but this crystal transparency was not pure, most of the texture was just mundane, and only a small amount of crystal fragmentation was bred in it.

"Uncle, is this stone also a mineral?" Xu Han didn't pay attention to the blacksmith's complaints, but just held up the spar and asked.

"It's just some useless stuff!" Tie Hong jumped on, took off his shirt and wrung out the water, and hurriedly put it on.

"Useless things?" the young man was stunned, "this stone looks quite extraordinary, how can it be a useless thing?" he asked, puzzled.

Tie Hong didn't look up with his clothes buttoned, "The first time I saw this thing was also in this cave, I thought it was a great thing, so I took some smelted liquid and thought about whether it could be cast into a divine weapon, but I tried many times but found that this stone was just an ordinary stone after removing impurities, and even this broken light would not be emitted after solidification." ”

After a pause, he continued, "After that, I thought about whether it could be used if I carved it directly, but I didn't want this jade to be brittle and cracked, and it couldn't be carved at all, and many methods were not available, so I had to give up, thinking that it was just a kind of stone that could emit some light, and it was not a big deal......

Xu Han pondered when he heard this, he held the stone in his hand, and with a little force, the crystal clear jade turned into powder in his palm, leaving only a few impurities in his hand.

The powder spread out, and a cool feeling followed, and the young man realized it and confirmed his guess. If it is not bad, this inferior crystalline jade is not really just a useless waste as Uncle Tie Hong said, on the contrary, it should be an extremely important resource!

The young man's six senses are extremely sensitive, although he is not a monk, but he is gifted, and he can vaguely perceive the qi of heaven and earth when the veins are not opened and the divine sense is not expanded. When he entered this cave, he was not shocked by this clear aura, but he was just surprised at why there was such a little vitality in this narrow cave.

Many places in this small world have been turned around, but only last night in the clear stream in the mountain, the ancient cave world has detected traces of vitality.

It stands to reason that this should not be the case, this person is undoubtedly defined as a cultivation world, otherwise the ancient cave under the peak, how could the ancient immortals in the cave be so miraculous, not to mention the endless ancient immortals who were sealed under the earth that Xu Han saw in the cave world.

That being the case, the qi of heaven and earth in this ancient village should not be so weak, but the surging vitality in the ancient cave is normal, even if it is not as good, it should not be left so little. When you think about it, there's only one reason. The young man's mind is heavy, and all the reasons are caused by the divine peak that separates the two worlds and can't see its determination even after exhausting his eyesight!

That mountain peak is not only blocking space, it may be in the void, and the vitality of heaven and earth cannot pass through this peak barrier! Therefore, everything in this paradise is like a mundane place, although there are indeed some wonderful things, but it is also not a treasure. The inferior minerals containing luck in front of me, and the strange beasts that I first encountered that night, were all just created by the vitality that had overflowed into this area for thousands of years.

At this time, Xu Han remembered what his father said, the ancient village has its back to the peak, and when you walk a few miles away, you will encounter a misty place, as if you are in a cloud and mist and it is difficult to distinguish things, no matter where you go, you will eventually turn back. If you think about it, that peak should be a real barrier to the human world, and it shouldn't exist in this ancient village that is not known to the world!
