Thanks to the rewards of "Caterpillar" and "Hero is difficult", I won't say anything, shake the claw.

-----------------------------------

Clearing the rocks was a big task, but just in case, he decided not to go around through the crevices above, but fortunately he had free labor, and a few corpses helped together, and the cleanup work was progressing very quickly!

Another hour passed, and the passage was about to be opened, when suddenly an iron-armored corpse "slammed" twice, raised its claws and took a few steps back.

What's going on?

Qin Chuan hurriedly came over to check, only to find that a blood hole had been pierced in the center of the iron corpse's claws, and he found that it was inappropriate, so he hurriedly asked the corpse to stop cleaning up the messy stones.

"Huh, how is this possible?" he soon discovered that it was a ray of light that pierced through the claws of the iron corpse.

Hesitating, he picked up a stone and approached the light, only to see that two or three inches thick was also pierced.

"Sizzle... It can't be..."Qin Chuan first thought of the radiation produced by some radioactive substance, and his scalp was a little numb for a while, and even a cold sweat broke out on his back.

"Haha, Qin boy, you are so lucky, what Lao Tzu didn't find when he launched the entire Tianlong Gate back then, was actually encountered by you so coincidentally. ”

"Senior Situ, what are you talking about?"

"Tsk, it's really unlearned, I thought you guessed it, this is called Gengjin Yuan Guangsha, if I'm not mistaken, this vein should be Gengjin mine!"

"Gengjin?" Qin Chuan had seen the introduction of this kind of thing from the Immortal Cultivation Treasure Book, this kind of material belonged to the metallic spiritual material, if the magic weapons of flying swords and flying knives were added to this material, the sharpness could be greatly increased, and the fan bone of the Three Treasures Xiaoyao Fan was also mixed with a little of this material.

"Yes, only the Gengjin vein has a certain chance of producing this kind of Yuan Guangsha, boy, it's a pity that your Xuanming True Qi is of earth attribute, if it is metallic, just with this Gengjin Yuan Guangsha, you will change to sword cultivation in the future, and the future is limitless!"

Situ Wuregret has always admired physical cultivation and sword cultivation, and he scorns other types of immortal cultivators, Qin Chuan has long been accustomed to hearing his tune, but he is still very interested in the specific use of this Gengjin Yuan Guangsha.

"Then is this useful to me? Is it the same as the Nine Yin Absolute Evil, which can only be used to refine the Evil Sect?"

"Of course not, after you build the foundation, you can use the true fire to refine the Gengjin Yuan Light into a sword element, and finally cultivate it into a sword fetus, although your true element attribute determines that you cannot become a top-level sword cultivator, but it is still possible to surpass the average master!"

"Do you have to wait for the foundation to be built?" Qin Chuan's interest immediately decreased, it was not something that could be used immediately, and he didn't know if he would have a chance to use it in the future!

"You kid... Alas... It's really a thunderstorm!" Situ Wuregret was completely speechless, this kind of blessing can't be touched by others, this guy actually has the mind to pick fat and thin.

Anyway, Gengjin Yuan Guangsha must be a good thing, put it away first, he just tested whether the Gathering Brake Bottle left by He Mingqi worked.

The whole body is cold and the collection of evil bottles is in his hand, this magic weapon he has already sacrificed, its internal space is composed of nine independent subspaces, the specific method of collecting evil, the jade slip of the collection of evil recipes is recorded.

The cork was removed, the mouth of the bottle was facing the golden light that passed through the stone, the magic trick was played, and a soft halo was emitted from the bottle, and a strange scene appeared, when the sharp golden light met the soft halo, it actually deflected, and it seemed to become a soft silk thread that was sucked into the bottle, and after dozens of breaths, the golden light disappeared completely.

Sensing the golden light that was beating in the space inside the bottle, Qin Chuan couldn't help but secretly admire, immortal cultivators could even collect this kind of ray, so is there a way to deal with nuclear weapons?

The chaotic stones were cleaned up by the corpse, and as a result, a golden light was transmitted throughout, so that a total of seven Gengjin Yuan Light Shatters were collected, and the entire passage was completely opened.

Feeling the feeling of his skin being scraped by a blade, Qin Chuan was sure that if it was placed in the era where he lived in his previous life, it would definitely be defined as a place with strong radiation, and ordinary people would not dare to approach it at all.

The cavern was clear due to the light transmitted by the rift above, with some ore scattered on the ground, as well as a few pickaxes that had been completely broken.

The pickaxes are special tools for mining, and judging by the degree of rust of these pickaxes, they have been abandoned for a long time.

For the sake of prudence, the two iron corpses opened the way in front, and Qin Chuan followed behind with the Gathering Evil Bottle, and collected more than 20 Gengjin Yuan Light Brakes one after another at a distance of dozens of zhang, until they reached the end of the entire cave.

There is a bit of a deviation from Situ Wuregret's judgment, this vein is a polymetallic associated vein, which is dominated by copper and gold, and perhaps heptane gold used to occupy a considerable proportion, but according to the current situation, the heptane gold here has been almost mined, so it was abandoned by the discoverer.

There is not much left, it means that there are still remnants, how could Qin Chuan let go of this precious material, he has long remembered the place where the Gengjin Yuan light is emitted, and the probability of the existence of Gengjin ore here is naturally the greatest.

In fact, as he expected, the yellow-white ore mixed with other ores is heptane gold ore, but the quality is relatively inferior, and at most it can only be classified as inferior.

It was extremely difficult to mine these ores, and the black axe quickly curled up his blade, so he had no choice but to use the scythe weapon to mine it.

When the last glimmer of light transmitted from the mountain crevice disappeared, and the busy day finally ended, Qin Chuan only obtained more than 20 pieces of heptane gold ore, if all these ores were refined, it would be good to be able to refine a pound of heptane gold, so he was very unwilling and decided to use his "mining weapon" to see if this vein ended here.

Saltpeter, sulfur and other materials are ready-made, after eating something, I took a look at the situation of Zhou Zixu and He Kui, and found that the vital signs of the two were good, indicating that there was no major problem, and he began to make a simple "detonator".

"Hey, what are you kid fiddling with?" Situ Wuregret found that Qin Chuan had used some alchemy materials, but it didn't look like he was alchemizing, but it was more like a refining tool.

"Hehe, this is called a cannon battle, you just wait to hear it in a while!"

I have to say that with the means of cultivating immortals, it is much easier to do things, such as hollowing out a piece of hardwood or stone core, which can be easily done with a flying sword.

Two hours later, the materials ran out, and a dozen or so ugly "cannon battles" were made, and a few holes were hit with flying swords according to the direction of the ore veins, and then the cannon battles were inserted into them, and as for the ignition, it was more convenient, just use the fireball technique.

"Boom" With several violent explosions, the whole cave shook violently, and the rubble fell, and its momentum was extremely huge, as if it was about to collapse, but fortunately, this kind of thing did not happen after all.

"Good boy, your cannon battle is a bit interesting, if you are proficient in refining weapons, the power of this thing may increase exponentially!" "Situ Wuregret's vision is so wide, he sees all the materials used by Qin Chuan, they are all ordinary things, but this power is really not to be underestimated.

Qin Chuan smiled, and when the smoke and dust cleared, he began to check the "results", it was Yuan Guangxu again! When he saw this thing, he knew that there was a play.

After collecting two Gengjin Yuan Light Evils, he really found a few pieces of yellow-white ore in the pile of rocks, and the quality was slightly better than the previous ones.

Once he succeeded, he was naturally full of energy, put all the remaining cannon battles in it, and then detonated them again, and the result was another harvest, but unfortunately the cannon battles were gone, and the materials for making them were also used up, so he could only mine them by hand again.

Suddenly, he heard movement in the mine behind him, and hurriedly released his senses, and at the same time secretly guarded, but when he found the person who came, he finally let out a sigh, "Zhou Daoyou, He Daoyou, you have finally woken up!"

The two of them looked sluggish, obviously not fully recovered, "Brother Qin, that blue-scaled python was killed by you, and what happened to the movement just now?"

Qin Chuan guessed that it might be that the movement just now was too big to wake up the two, but he didn't intend to tell the truth, "Oh, this is an abandoned mine, I found a small amount of heptane gold ore, which is being mined!"

"What??," the two men asked, almost in unison.

"Well, the quality is too poor, you see..."

The two of them took it over and took a closer look, the expression on their faces immediately became colorful, and the malaise just now was swept away, they had already seen that this was not the Ancient Xiu Cave Mansion at all, and they originally thought that this trip was a big loss, but they didn't expect to have an unexpected gain.

"Don't be too happy, the ore veins here have long been scrapped, and it took me half a day to get a few pieces!"

Zhou Zixu and the others didn't show disappointment when they heard his words, "Brother Qin, people should be content! Do you know what the price of Gengjin is now?"

Qin Chuan shook his head, he only knew that this thing was relatively rare.

"Hehe, just before we came, at the auction of the foundation building period, there was a piece of heptane gold weighing about one catty and two taels, which was auctioned at a high price of four thousand spirit stones, let's not have more, as long as we get a few taels, at least we can fight for a few years!"

Regardless of the fact that their bodies had not yet recovered, the two took out the pickaxe from the storage bag and immediately started working in full swing.

It turns out that there is really not much "oil and water" in this mine, and each person can still mine a few pieces of ore in the first few days, and there is no harvest after the tenth day, Qin Chuan received three more Gengjin Yuan Guangsha, Zhou Zixu and He Kui also guessed that this is a good thing, but unfortunately they have no ability to collect it, and in the end they can only cheapen him.

"You two, I don't think there's any need to waste any more time!"

"Qin Daoyou, in two more days!" He Kui was obviously still a little unwilling, and Zhou Zixu was silent.

"Well, if you don't want to leave after two days, then I'll take my leave!"

Three days later, the two stayed in Cangyun Mountain in the name of hunting demon beasts, how could Qin Chuan not understand their plan and didn't want to break it, so he chose to return alone.
