In the Refining Pavilion, all the metals and ores that Xiang Tianyi brought were refined.

In this world, there are not only ordinary metals such as gold, silver, copper, and iron, but also higher levels of existence such as refined iron, refined copper, refined silver, and pure gold.

This kind of high-level metal is very rare, and it is usually the material used by martial artists above the Bone Refining Realm to forge weapons, and the ordinary metal above the Bone Refining Realm can no longer hurt its flesh, and only with this high-level material can a weapon that hurts people be created!

At the same time, the ratio of metal is also very important, a good weapon must not only have good hardness but also have considerable toughness.

In addition to ordinary metals, most of the metals brought to Tianyi are refined iron and refined copper, and the amount of refined silver is very small, and the pure gold is only a piece the size of a fist.

In terms of hardness, fine iron is the hardest and softest, but in terms of value, pure gold is the most expensive and cheapest.

According to Elder Feng, the value of pure gold lies in the fact that it can break through the protective battle qi of the powerhouses of the Refining Marrow Realm, so there is no price in the world.

The ratio and use of Adamantite in weapons is quite the level of a refiner, and using good materials does not necessarily make a good weapon.

A weapon that is all refined from higher-level materials is considered a yellow-level soldier, and the yellow-level soldier can be divided into three classes according to its power, which are the yellow-level lower grade, the yellow-level middle grade, and the yellow-level upper grade.

In terms of refining, Feng Lao is the best refiner in Gushan Town, but it is still difficult for him to refine a yellow-level soldier.

One of the best weapons refined by Feng Lao is a sword mixed with a little fine iron in ordinary metal, named Fenghua Sword, this sword is extremely sharp, and it can easily break its weapon in a fight......

As soon as Xiang Tian had the Star Chasing Dragon Yin Sword in his hand, he naturally didn't need Feng Lao to practice swords for him, but simply made a batch of bullets with refined iron and refined copper alloy, and plated 100 of them with pure gold, even if it was only plated with a layer, but the 100 warheads also consumed half of the pure gold.

After putting all the refined metal back into the Desert-Eagle, Xiang Tianyi took out the Star Chasing Dragon Yin Sword that now looks like an ordinary big sword, and under a closer look, there are many gaps on the blade, just fighting with Xiang Xuanyu, this big sword coat has been tattered, if you continue to use it, it is estimated that it will all fall off after a few times.

This sword is a master's sword, and it has a great stake! If it is recognized when his strength is low, it will be a big trouble.

Taking off the outer garment of the sword body to see that the gauntlet and hilt of the big sword were still intact, Xiang Tianyi decided to keep it.

With the help of Feng Lao, he remade a sword body coat with refined iron and refined copper alloy, and after the exquisite fancy dragon pattern was covered, it looked like an ordinary big sword.

Bidding farewell to Feng Lao, Xiang Tianyi returned to his small courtyard again, and happened to see Xiang Yuan pacing back and forth in the courtyard......

With Xiang Yuan's current identity, he has already had his own mansion, but he has a lot to do with Xiang Tianyi, and he wants to enter and exit Xiang Tianyi's courtyard, so naturally no one will stop him.

Seeing Xiang Yuan like this, Xiang Tianyi thought something was wrong, and asked while trotting forward, "Brother Xiang Yuan, what's wrong with you?"

Xiang Yuan also turned around and looked at Xiang Yuan when he heard this, and Xiang Tianyi realized that Xiang Yuan was pacing anxiously, and he was clearly excited!

"Tianyi, it's time to wait for you! Something to tell you......" After Xiang Yuan saw Xiang Tianyi, he didn't have a polite greeting at all, and went straight to the point.

It turned out that Xiang Yuan was recently assigned a task by the family, which was to integrate all the mining areas and ore veins of the three major families, not only to check the map information handed in by the three families, but also to disrupt all the mine disciples and redistribute the mining area, and each mining area must have Xiang family disciples to participate.

During the integration period, Xiang Yuan found that a circle was drawn on the west side of a remote new mining area on the map of Liu's family, and the danger was specially marked.

He asked a disciple of the Liu family to ask, it turned out that this was a natural cave, the entrance of the cave slowly extended downward, and the cave was unfathomable.

The Liu family came here 25 years ago to explore the ore vein, a disciple found this hole, and then the Liu family sent someone to check, the result was a heavy death, according to the disciple who escaped death, there is a very powerful demon beast in the depths of the cave, they just found out that most of the dead and injured.

Later, the Liu family organized several powerhouses of the Bone Refining Realm to enter, but they were all frightened and retreated when they felt the aura of the demon beast from afar!

It is speculated that the demon beast is at least a low-level demon beast of the Xuan level, and its strength is comparable to that of a strong person in the Bone Refining Realm, and the strongest person in the Liu family at that time was only the peak of the Bone Refining Realm, so how could he dare to take risks easily, so it was specially marked on the map, so as not to let the disciples or mining slaves mistakenly penetrate the mine cave with it......

Xiang Yuan followed Xiang Tianyi and had many treasure hunting experiences, and when he heard it, he felt that most of the treasures in this cave were hidden, so he immediately looked for Xiang Tianyi to discuss whether he could explore it.

Xiang Yuan came to the small courtyard, but did not find Xiang Tianyi, so he waited here for him to come back, and during the waiting period, Xiang Yuan thought of the treasure guarded by the Xuan-level demon beast, and his heart was extremely excited, so there was a previous scene.

Xiang Tianyi's brows furrowed slightly after hearing this, and when he heard this situation in the cave, he also felt that there should be treasures, but why did Ren Lao never mention this?

"Brother Xiang Yuan, show me the map of the Liujia mining area. "To the sky.

Xiang Yuan immediately took out the map from his arms and handed it over.

Xiang Tianyi spread out the map on the stone table, and began to ask Ren Lao in his consciousness.

"Hehe, Tianyi boy! This cave is too far away, old man, I can't detect it at all! This treasure exploration also has a range, and I can't sense it beyond the range!" Ren Lao explained with a smile in his consciousness.

"I see!" Xiang Tianyi suddenly said.

"Brother Xiangyuan, let's go and take a look!"

Since he knew that this place was not within the scope of Ren Lao's exploration, Xiang Tianyi was of course very interested, so he pulled up and walked away.

Xiang Yuan couldn't wait, so the two rushed directly to the gate of Xiangfu......

On the way, Xiang Tianyi handed over the star-chasing dragon sword imitated by Feng Lao to Xiang Yuan, although it was not a divine weapon, Xiang Yuan still liked it very much.

The two did not detour directly over the mountains and mountains, about 50 kilometers away from the cave drawn on the map, Ren Lao sensed that there was indeed a treasure breath in that direction, and it was very strong, Xiang Tianyi only knew that Ren Lao's treasure exploration sensing distance was at least about 50 kilometers away.

It is about 5 kilometers west of the Liujiaxin mining area.

Xiang Tianyi and Xiang Yuan stepped into the deep cave, the cave was first an open area, full of natural vines, strange stones, as the depth of the cave gradually narrowed relative to the cave entrance, but the width and height were at least 10 meters away.

Such a wide cave makes Xiang Tianyi more and more frightened, if there is only one demon beast, it would be fine, if it is a group demon beast like the highly poisonous sky tarantula, I am afraid that this trip is dangerous!

"Ren Lao will do his best to help me investigate, and you can pick whatever you want!" Xiang Tianyi said to Ren Lao in his consciousness.

"Hehehe! Okay! It's not the first time this old man has done it, so you can rest assured! There are no demon beasts within 100 meters at the moment. Ren Lao said with a smile.

"What?100 meters?, Ren Lao, can your divine sense cover so far now?" Xiang Tianyi said excitedly when he heard this.

"At the beginning of the No. 4 vein, my memory was just a short time of cultivating immortals, and at that time I could detect a distance of ten meters, but now my memory has recovered to the late stage of foundation building, and detecting a hundred meters is nothing. Ren Lao said.

"That's a hard job! This time it's a ruthless character, we have to be very careful!" Xiang Tianyi admonished.

Moving on, the two of them walked down for about half an hour before the cave gradually calmed down.

"Tianyi, look ahead!" Ren Lao reminded.

There is no need for Ren Lao to remind him, Xiang Tianyi has already seen that there is a light at the end of the dark cave.

"Is it already at the other exit? Is this cave empty? No! No way. This cave has been going down for so long, it must be deep underground at this time, and there can be no exit to the outside world, then there is only one explanation, there is a pit that connects to the ground. Xiang Tian secretly guessed.

After a pause, Xiang Tianyi once again took out more than a dozen torches from the Desert-Eagle and handed them to Xiang Yuan.

"Brother Xiang Yuan, this time is different from the last time, from now on, start to plant torches, and stick them on the stone wall every 10 meters forward. Xiang Tianyi confessed.

Since there is a bright light ahead, if you encounter danger and want to retreat, your eyes will inevitably be extremely uncomfortable, and it will be too dangerous to be unable to distinguish the direction or see the road in this dark hole.

Now Xiang Yuan still has absolute trust in Xiang Tianyi, he chose a stone crack with the torch in his hand and inserted it, nodded and said, "Okay, listen to you!"

As they went, just as they reached the eleventh torch in the distance, the two of them also came to the bright and glaring hole.

Squinting his eyes, Xiang Tianyi endured the discomfort of alternating light and dark, and looked out.

Sure enough, this is a pothole, the vines on the wall of the hole are intertwined, all kinds of plants grow in a staggered manner, and occasionally you can see some small insects, they crawl or fly, birds sing and flowers are fragrant, a good cave blessed land!

At this time, Xiang Tianyi didn't know if it was real or an illusion, but he felt that the aura here was strong, and it seemed that it would be of great benefit to be able to stay for a while.

I couldn't help but take a deep breath, but I felt that my cultivation had increased slightly......

"Hiss~!"

Xiang Tian turned his head to look, but Xiang Yuan was doing the same thing as him at this time.

"It's not an illusion, Brother Xiang Yuan, do you also feel the strong aura here?" said Xiang Tianyi in surprise.

Hearing this, Xiang Yuan also seemed to react from intoxication, experienced it again, and exclaimed: "Tianyi, I feel like I have returned to the experience of entering the medicine pool before, and it is very comfortable!"

Xiang Tianyi's eyes widened when he heard this, you must know that they are all powerhouses in the Bone Refining Realm now, and they need far more spiritual energy than in the Flesh Refining Realm, not to mention the feeling of ordinary people when they first enter the medicine pool.

If that's the case, wouldn't that mean that staying here and cultivating would be as fast as refining the Skin Realm?

Or maybe the treasure here is extraordinary, and just the breath it exudes can make such a Jedi a fairyland on earth?

The two couldn't help but step out, and the first thing they saw was another hole that appeared opposite them.

Obviously, as Xiang Tianyi guessed, this is a big hole, which cuts off the cave, and neither of them looks up to look up, because the dazzling light shines directly from above, and the two of them are subconsciously ready to go to the opposite cave entrance first......

As soon as he took two steps, Xiang Tianyi was trembling, Ren Lao was already anxious, and directly transmitted the information detected by his divine sense into Xiang Tianyi's consciousness, and at the same time, the voice came, "Tianyi boy! Danger, go quickly......"
