The spirit invaded the square metal box, and Levi felt that his spiritual power that had spread from his 'analytical' ability was hindered.

He cautiously increased the output of spiritual power, and in the face of this unknown item, Li Wei still didn't dare to pour too much spirit into this thing in one go, so as not to have any bad effects. If you put in less mental energy, even if you are really in big trouble, you can withdraw in time.

With the investment of energy, the 'analysis' ability that has just been upgraded once has been upgraded to a level, and it is very difficult to parse the information of this box.

"Ancient metal: The age of the metal of this material cannot be verified, and the age of its manufacture is about 2,000 years ago. The outer metal has excellent energy and spirit insulation properties, and is a very good sealing material, and it is also very strong. ”

"Ancient Beads Crafted from the Earth's Core Divine Crystal: The beads polished from the 'Earth's Core Divine Crystal', in this ancient metal box, the six crystal beads act as switches. Operates with some complex mechanism that controls the seal strength of the Ancient Metal Box. ”

These two paragraphs are a summary of the information that Li Wei obtained through his 'analytical' ability to the outer packaging of the box in his hand. And the final result surprised him very much.

The characteristics of the two materials are different, but according to the analysis results, they are both top-level materials that have reached the level of the main material of the artifact!

The Earth Core Crystal itself is a very rare and famous thing. It's just that the general Earth Core Divine Crystal should be an irregular polygonal body, and it is extremely difficult to process, and Levi has never heard of anyone who can make the Earth Core Divine Crystal into a regular circle.

And the ancient metal is completely out of Levi's understanding. With the infusion of knowledge brought by infinite alchemy, he usually mixes in the market, and his knowledge reserve in materials is already very rich.

However, despite this, he still couldn't recognize what the metal on the outside of the box was, so he could only name it 'Ancient Metal', and barely analyzed some of the properties.

But that didn't prevent him from confirming that this 'Ancient Metal' was a high-grade artifact main material.

Unlike artifacts, which are divided into inferior, medium, and superior, the main material of divine weapons is only ordinary and superior.

Generally speaking, it is great that a single divine weapon main material can be made into a second-class artifact, and a medium artifact generally requires multiple divine weapon main materials to be created together.

And the high-grade divine weapon, that is, another level of things, must be matched with at least one or more high-grade divine weapon main materials to be able to be manufactured.

With Levi's current alchemy ability, the success rate of forging inferior divine weapons is good, and medium divine soldiers can also try it, but the main materials of divine weapons are not so easy to do. But the superior divine soldier, that's something you can't even think about, it's not that Levi is not confident, but he definitely can't do it.

But this does not prevent the preciousness of the finest main materials.

However, whether it is the 'Earth Core Divine Crystal' or the 'Ancient Metal', the role of such a precious material in this box is just a 'container'?

What's in there?

It's scary to think about.

After completing the analysis of his appearance, Levi took a short break and regained some of his spirits, and then began to plan to continue his inward exploration.

He was so curious, and he had a vague feeling that he had found something very strange.

He vaguely felt that this box might be the most important reason for the formation of the heart-tearing giant ghost that had been raging in the bottom area for many years and no one could cure it.

After having experienced it once, this time the spiritual invasion was very familiar, and it quickly penetrated through the periphery of the earth's core divine crystal and ancient metal, and penetrated deep into the interior.

The next moment, Levi seemed to be in a dark yellow twisted world. There was no sky, no ground, and his entire spiritual body was in nothingness. Large expanses of thick yellow clouds gathered towards Levi's spiritual body.

In an instant, the storm formed, and Levi became the center of the storm like the eye of the storm.

These thick yellow clouds, twisted and chaotic, ancient and full of evil thoughts. This energy was constantly tearing at Levi's spiritual body, and at the same time, it was constantly invading, transforming, and assimilating his spirit.

All of this happened in an instant, his eyes turning scarlet, and the scythe of the windmill spun rapidly.

At the moment of attack, the Sharingan was opened. The power of the spirit was running wildly, resisting the invasion of these strong yellow powers.

Temporarily slowing down the speed at which the spirit body was being invaded, Levi began to look for a way to escape.

He had to rejoice that his previous behavior was still relatively cautious and restrained. This intrusion into the spirit body within the square box is only a small part of his overall spirit, not all of it. Therefore, he can use the ontology to resist erosion and tearing while relying on the spiritual protection ability brought by the writing wheel eye to resist erosion and tearing, and at the same time strive to pull the divided spirit back.

If it really comes to the worst case, he can also directly cut off the connection between the body and the separated spirit, and the strong man will cut his wrists. Although, that would cause mental damage to it, it would certainly be much better than being invaded by this ancient and disgusting power.

But fortunately, things didn't get to that point.

In the end, he still pulled the separated spirit back to its original body.

His eyes lit up, and his spirit returned to the real world. The metal box held in his hands, on the six sides of the six round earth core divine crystals, was spreading some thick yellow mist outward.

The demon's left hand lit up with the power of thunder, instantly dispersing these mist. The metal box trembled twice, and Levi seemed to hear an unwilling roar, and then the box returned to calm.

Putting the metal box back on the table, a slight cold sweat broke out on Levi's forehead, this thing was a little scary.

This mental invasion did not get any good results. He didn't fully understand what was sealed in this box, and he didn't dare to break the seal, and he didn't think he had the ability to do so. But the ancient and terrifying power inside made him remember it vividly.

It seems that this is how the heart-tearing giant ghost was created. The guy was supposed to be a human, or a mutant, and somehow got his hands on the box. He may have studied this strange thing as closely as Levi, or he was corrupted by the energy passively released by the Ancient Box, but he was unable to resist it, so his soul was annihilated, his body mutated, and he became a brainless monster.

In the case of unsealing, just relying on a part of the power leaked, you can create a monster like the Heart-Tearing Giant Ghost with a power level of truth, how terrifying should the energy contained in this box itself?
