In the past, when he was in the blacksmith shop, there was an iron mine outside Hanxiao City, and Xu You often went to dig it, and then came back to smelt it into pig iron.

After a while, Xu You's bamboo building was piled up with a lot of ore.

On the other side, Lin Xueqiao, one of the five masters of the outer gate of the refining peak, also came to the big pit, but her cultivation was profound, and she was already at the third level of qi refining, and other outer disciples could only go down slowly along the road carved out of the rock wall of the mine, but she was like a falling goose, stepping on some protruding stones, and she actually fell dozens of feet like this.

Seeing this scene in the eyes of those miscellaneous disciples and outer disciples, it was naturally another burst of admiration.

Reaching more than thirty floors below, Lin Xueqiao's figure flashed, stepping into the mine cave on this floor, compared to the above, it was like another world, there were already some poisonous gas mist miasma here, and there were even more demon beasts entrenched in the depths of the mine, no miscellaneous disciples dared to come down, even ordinary outer disciples did not dare to come down, those who could haunt here were the best among the outer disciples of the refining peak, or the inner disciples,

Naturally, the quality of the ore that can be collected here is also quite high, far from being comparable to the above.

When Lin Xueqiao came here, she naturally came to collect refining materials, but she could drive the flying sword and didn't need to use a mine hoe, which was naturally trouble-free and efficient. It's just that almost all the ore in this edge area has been emptied, so Lin Xue Qiaolian moved lightly, and her body turned into a green rainbow and entered the depths.

The third layer of qi refining can already spread the aura all over the body, cast spells, and control magic weapons, and the miasma here is under the influence of the pair of earring magic weapons in Lin Xueqiao's earlobes, and it is impossible to get within three feet at all. A moment later, she had arrived in a rare place, surrounded by a thick miasma and empty, while there were stars shining on the rock wall in front of her, which were obviously some rare crystals.

"Here it is. Lin Xueqiao took out a wide and heavy magic sword from the storage bag on his waist, this magic sword did not have any magical powers, but if it was driven to mine, it was much stronger than manpower.

"Go!" Lin Xueqiao pinched the sword trick, the jade hand continued, the wide magic sword had already flown out, as if holding it, it was jingling on the rock wall, and after a while, many crystal ores fell below.

Lasted for half an hour, Lin Xueqiao was already sweating on her forehead, after all, the sword technique consumes mana very much, she is only a third layer of qi refining, and the sword can't last, besides, the rock wall here is harder because of the crystal ore, if it is not mined by the magic sword, the ordinary mine hoe is afraid that even a piece of rock skin will not be able to be chiseled.

The crystal rock wall here was discovered by Lin Xueqiao by chance, and few people came on weekdays, but after her many diggings, there was already a hole in the rock wall. Just when she rested for a while, swallowed a Hui Qi Pill, and urged the magic sword to chisel a few times again, suddenly the wide magic sword seemed to hit something extremely hard, and it actually clicked, and the sword body shattered.

Lin Xueqiao was stunned.

Although the magic sword she used for mining was only extremely ordinary, it was also forged from stainless steel, and the tip and blade of the sword were quenched by secret methods, how could it be shattered by a mere rock wall.

Unless......

Lin Xueqiao's eyes lit up at this time, and she thought of a possibility, only some extremely special and high-quality crystal ores have such hardness, even if she is one of the five masters of the inner gate of the refining peak, but she does not have high-quality crystal ores, so at this moment, she looked forward to it, and stepped forward to check, but at this look, Lin Xueqiao was stunned again.

In the rock wall that she had chiseled with her magic sword, a metal horn was actually exposed, and it was obvious that it was this metal full of strange patterns that had broken her magic sword just now.

She took out another magic sword and slowly cleaned up some of the surrounding rocks, revealing more, and then she looked at it, and her heart moved, and she recognized that it was actually an iron coffin.

There is an iron coffin in the rock wall inside the pit, is there anything more weird than this?

Although he is one of the five masters of the inner door, Lin Xueqiao has never seen such a strange thing, although he senses that something is wrong, but people's curiosity comes up, sometimes he will always ignore it, especially women's curiosity is several times stronger than that of men.

Lin Xueqiao is also self-sustaining, after all, she is a third-level Qi refining cultivator, and she is already a top existence in the outer gate, so although she is shocked, she is not afraid.

"I'll see what it is. Lin Xueqiao took out another magic sword and spent time digging the entire iron coffin out of the rock wall. After revealing the full picture, even Lin Xueqiao secretly admired that this iron coffin itself should be an amazing magic weapon, with complex lines on it, and a hard texture, it is difficult for ordinary magic swords to even leave a scratch on it.

"Could it be the magic weapon used by the Demon Dao?" Lin Xueqiao heard that the exercises practiced by some Demon Dao monks were strange before, but this iron coffin didn't know how long it had been buried here, and it looked dense, if there was someone inside, it would definitely be a dead person.

It's just that Lin Xueqiao didn't know that just as she was digging out the iron coffin, a roar came from the depths of the mine. Then deep underground, under the rotting soil, many dried corpses crawled out, like wolves that could smell fish, and began to walk towards the location of the iron coffin.

The depths of the pit are rarely visited, so no one sees this change.

Xu You was sweating profusely here, although he had been cultivating hard in the Cold Sword Gate for more than a month, and had not yet stepped into the first layer of qi refining, his physique was much stronger than before, although he still looked a little thin, but waving the mine hoe was also a tiger, and in less than an hour, the bamboo basket he brought was already full of ore.

They are all some iron ore, and the highest quality is not more than three grades, of course, take it to the furnace for refining, you can also get a few catties of refined iron.

Xu You knew that there was a furnace spot nearby, so he packed up his things and went to smelt with a bamboo basket on his back. There is no way, Xu You doesn't have a Qiankun bag, he can't dig too much at a time, according to Xu You's idea, after having a contribution point from the sect, in addition to buying some pills for cultivation, the rest has to be accumulated, no matter how you say it, you have to get a Qiankun bag, even if it's just an inferior Qiankun bag. It is said that in the inferior Qiankun bag, there is also a three-foot square place inside, which is worth at least three bamboo baskets, but the inferior Qiankun bag also costs hundreds of contribution points, and Xu You can only think about it now.

All the way to the smelting point, Xu You looked at the dark path and was lucky, this smelting furnace was actually not used, and he immediately walked quickly, and when he got closer, he could feel a heat wave.

The furnace set up by the refining peak is engraved with a first-level fire array, and there are ten years of charcoal refined by the refiner, which means that after this furnace is set up, it can be burned for ten years without extinguishing.

Xu You began to smelt the ore dug out by himself at this time, under the fierce furnace fire, the refined iron melted and remained, the impurities were removed, back and forth, in less than half an hour, Xu You smelted all the iron ore in the bamboo basket, and finally got five catties of refined iron.

After taking a sip of the water in the cowhide water bag, Xu You was about to go back to continue mining when a strange sound made Xu You stunned in place.

Just a few feet away from the furnace, the dirt on the ground began to churn, as if something below was about to break through.

And the next moment, a rotten and stiff hand stretched out from the dirt, which made Xu You startled.

"Ghouls?"

Xu You felt that his legs and stomach were cramping, although he had only been in the Cold Sword Gate for more than a month, he was not the kind of rookie who knew nothing about the cultivation world, not to mention anything else, just said that he came to the mine to mine, at least he had to have an understanding and cognition of the dangers in the mine.

And there is no doubt that the corpse demon is one of the most dangerous beings in the mines.

This mine has existed for more than a thousand years, and tens of thousands of people have died here, and it is said that five hundred years ago there was also a piece of superb earth crystal here, which is a material that can refine a ground-level magic weapon, for which several major sects came here to fight for the death, and that battle lasted for several months, I don't know how many monks died, and I don't know how many monks buried their bones here.

The mine cave is hidden in the ground, the yin and evil atmosphere under the bottom is heavy, and the corpses of these monks have become corpse demons over the years, when the Cold Sword Gate was founded, there were Han Jianmen monks who came to clean up these corpse demons, although they got rid of a lot, but the deepest part of the mine is difficult for even the masters of the Cold Sword Gate to set foot on, fortunately, most of the corpse demons have no intelligence, except for the corpse demons in the depths of the mine will not go out easily, and even if there are two or three kittens in other places, it is not enough evidence, so the Cold Sword Gate has already let it go.

Generally speaking, it is unlikely that there will be corpse demons in these fifteen-layer or so ore layers, but I didn't expect Xu You to go out today without looking at the yellow calendar, and he actually met one.

At that moment, Xu You's scalp was numb, and he wanted to escape, but before he moved, the corpse demon underground had crawled out at a very fast speed, letting out a shuddering low roar, and a pair of milky white eyes without pupils stared at Xu You.

This time, Xu You didn't dare to move.

The classics in the Cold Sword Gate include clouds, corpse demons, soul and death, pregnancy in the atrium, flesh and bone like iron, minions like hook thorns, corpse poison, hairless body, all iron can be injured, Qi refining monks are easy to kill, those with hairy bodies, white hair is difficult to hurt by iron, the first layer of Qi refining is difficult to be beaten, the red hair magic weapon is difficult to hurt, the third layer of Qi refining is difficult to be defeated, the black hair encounters it, and the fifth layer of Qi refining is quickly escaped.

Every disciple who comes to mine is familiar with it, after all, it is related to his own life, of course, as long as he does not go deep into the mine, he will not meet a corpse demon, but the problem is that Xu You has an idea to carry today, and he actually met one.

And if you look closely, the sweat on your neck is coming out, and it's actually a white-haired corpse demon.

The white-haired corpse demon, the refining weapon is difficult to defeat on the first floor, Xu You is not even the first layer of qi refining, where is the opponent, if the seven-star magic sword is in hand, Xu You can also fight hard, but it is a coincidence that the seven-star magic sword is waiting to be tasted in the sword pavilion, and the only weapon in Xu You's hand now is the inferior iron sword issued by the sect.

Xu You only felt that his luck was on his back to the extreme.
