Yesterday morning, Dongyang also asked himself if he could find an opportunity to bring back the ebony trees that had been cut down at the beginning.

As a result, as soon as the day dawned today, a treasure no less than the ebony tree was obtained.

Wiping the soil on the surface, Li Youdao stroked the stone in his hand, or rather, black iron ore.

This ordinary iron ore, which was eroded by the energy of another world, has almost evolved into a completely different substance after a long period of mutation.

It can be said that to a certain extent, this is the natural equipment bred by Mother Earth, and it is a gift from this world to mankind.

The difference with monster breeding equipment is that this black iron ore has no attributes.

Just like the hexagonal ring and the glass ring, these two pieces of equipment are one of the spirit attribute and the other is the soul attribute, which can amplify the mage and the Taoist respectively.

And this kind of black iron ore is attributeless, that is, it cannot increase any otherworldly energy.

It may seem like Mother Earth playing a joke on us, but in reality black iron ore has other uses.

That's what Li Youdao thought of before - devouring.

Whether it's the best equipment with spiritual intelligence, or the ordinary equipment bred by monsters, as long as it is fused with black iron ore, it will be greatly improved, which is the growth of the origin of the equipment, and its unique no attributes, after being fused, will also change to the same attributes as the ontology.

Coupled with the fact that the black iron ore does not possess intelligence and attack ability, this fusion is extremely easy and there is no danger at all.

Therefore, once the best equipment with spirit encounters this kind of black iron ore, it will try its best to devour it, and once it succeeds, its strength will increase greatly.

As for ordinary equipment, it requires human beings to provide technology, that is, forging, as long as the black iron ore is smelted into ordinary equipment, then the entire ordinary equipment will also be greatly improved, of course, some materials do not support forging, such as hexagonal rings, low-level bone equipment can not be forged.

But even so, Li Youdao was very happy, because forging was not just about fusing black iron ore into ordinary equipment.

You can also smelt ordinary equipment with attribute amplification into a large amount of black iron ore, so that you can use the attribute amplification of ordinary equipment to create a large number of standard equipment with the same amplification effect!

This is also the most used equipment by humans in the last days, just like the bronze axes, bronze swords, short swords, etc., which were mass-produced by humans in the previous life, and these equipment played a vital role in the human fight against monsters in another world.

After "Hum ......" saw the black iron ore, the broken soul instantly became restless, but at this time, he had been subdued by Li Youdao, and naturally he needed Li Youdao's consent to devour the black iron ore.

Resisting the restlessness of the broken soul, Li Youdao looked at the surrounding earthen walls and pondered.

As far as he knew in his previous life, this kind of black iron ore was only available in the mine, and Li Youdao chose a location far away from the mining area and the skull cave because of the safety of the camp, so theoretically there should not be such a single piece of black iron ore here.

"Could it be ......" thought of a possibility, Li Youdao's eyes suddenly flashed: "Keep digging", and gave an order to the mutated skeleton on the side, Li Youdao carefully observed the reaction at the bottom of the cave.

Fortunately, the mutant skeleton has a huge strength, otherwise it would not be so easy to complete just transporting the sand out.

As the minutes ticked by, the ground below grew harder.

"Dang!" Another soft sound came out, and Li Youdao hurriedly stopped the movement of the mutated skeleton, came to the source of the sound, and leaned down to observe it carefully.

The light of the emergency light shone on it, reflecting the object below in a golden yellow: "It's a copper mine...... Looks like I guessed correctly, this location is supposed to be connected to some part of the mine. It's just that I didn't expect that the mining area that extends in all directions would extend here, and if it weren't for the keen perception of the broken soul, I am afraid that no one would find this place for hundreds of years......"

Thinking of the key point, Li Youdao shook his head again: "No, maybe it was the soul breaker of the previous life who successfully took this piece of black iron ore, which caused no one to discover the abnormality here for a hundred years in the last century." “

"The cycle of cause and effect is really wonderful...... "Sighing again, Li Youdao continued to order the mutant skeleton to dig down.

This time, however, the excavation slowed down because the ground below was getting harder and harder, and there were more and more non-mutated ores such as some ordinary copper ore and iron ore.

Seeing that the excavation had become difficult, Li Youdao nodded secretly, the entire mining area was surrounded by various minerals, which were extremely hard, so it was normal for the excavation to be slow.

In the last life, there were many people who were trapped in the mining area and could not get out, and almost everyone in them tried to make a hole to escape, but unfortunately most of them did not have the tools to dig with their bare hands.

And even with the tools, they can't break through the hard ore layer, and the monsters roaming around, and the direction of digging from the bottom up, no one has ever succeeded in this method.

However, these can't stop Li Youdao, firstly, Li Youdao is digging from top to bottom, and secondly, the strength of the mutated skeleton is obvious to all, and it is not an ordinary human force that can compete with it, so even if the progress is slow, it is still effective.

"Dangdang ......" With the contact with the ore layer, the sound of the whole excavation has changed, from the initial digging sound, and now the clanging metal collision sound: "If you are lucky, there will be black iron ore." ”

Carefully observing the situation on the ground, Li Youdao was afraid that he had missed a piece of black iron ore by mistake, although this kind of black iron ore is relatively rare, but in the case of large-scale excavation, the output is still very considerable, otherwise it would not be called a gift from Mother Earth.

"Boom ......" suddenly a strange sound came, followed by a slight stench!

The emergency light quickly turned on, and the light spread evenly across the bottom of the cave, and Li Youdao quickly looked for the location of the sound.

I saw that in the corner of the bottom of the cave, in the gap of a few pieces of ore, a bit of dirt, convex and convex, surging upward.

And as the changes became more and more frequent, suddenly a huge head broke out of the ground!

The dirt covering its face could not hide its internal decay, wisps of green liquid flowed from the corners of its mouth, and its pale eyes turned aimlessly, as if they were not very accustomed to the sudden light source, and the nose, which had been smoothed out by drilling in the ground, pulled out more green putrefaction with the swing of the head.

"Click!" As if he had finally found the target, the head suddenly turned its head at a strange angle, staring at Li Youdao not far away.

"Roar!" The pitch-black mouth opened suddenly, the black teeth were like sharks, as if they could bite steel, and a dark green tongue trembled with the roar.
