Residue layer, humus layer, viscous layer, calcium accumulation layer, ash layer......

Richard walked through layers of soil formations, sinking about a meter or so into the rock.

At this time, the ease of swimming fish in the water disappears, and is replaced by a sticky feeling of entering the glue, a little more resistance and discomfort, but still free to move.

Calming down, he traced the source of a mental fluctuation in the mountain and continued to sink, trying to find possible cracks and passages in the process. After all, only when a crack or passage is found can the flesh enter from the outside world. But after looking for a long time, it didn't work, but the fluctuations from the spiritual source became stronger and stronger.

Continuing to sink dozens of meters, the feeling of shuttling in the glue suddenly disappeared, the consciousness body suddenly lightened, and a space inside the mountain appeared in front of me.

The space is not very large, only the size of two houses, but it is square and has obvious traces of artificial construction.

That's weird.

"There is no passage connecting the inside and outside, but there is an inner space, how is this built? build a secret room first, and then build a mountain outside? or, with some kind of spell?" thought to Richard, looking ahead.

In the center of this space, there is a two-story altar, and on top of it is a crystal skull, which is crystal clear and lifelike.

After seeing the crystal skull, Richard's heart moved, and he couldn't help but think of some related legends on the modern earth.

Legend has it that in ancient times, there were 13 crystal skulls on the modern earth, which could speak and sing. These crystal skulls hold knowledge about the origin and death of humanity and help them unravel the mysteries of life in the universe. And humanity must find all 13 crystal skulls before the end of the world, otherwise the world will be destroyed when the 5126-year calendar ends.

There is also a legend that there are a total of 52 crystal skulls, scattered all over the world. The 13 mandibles are movable, called "singing skulls", which store a wealth of knowledge and are gifts from a mysterious civilization. The other 40 mandibles are immovable, called "talking skulls", which do not store knowledge, but can use power to help humans improve some abilities, such as physical strength, endurance, agility, intelligence, etc., to become guardians and help spread the knowledge in "talking skulls".

Legend has it that the crystal skull was an offering to the sun by the Aztecs, the original inhabitants of Mexico.

Legend has it that the Crystal Skull was a sacred relic, and when collected, it summoned the powerful Quetzalcoatl God.

In short, there are various legends, the rumored crystal skull is half the size of a normal human head, but the crystal skull in front of him is even smaller, not even a quarter of a normal human body, and can be grasped in his hand.

At this time, the crystal skull, which seemed to be miniature but was actually dangerous, was constantly releasing mental fluctuations towards the outside world, and Richard approached cautiously and tried to study it.

Five, four, three......

Suddenly, when approaching the altar and reaching a place three meters away from the crystal skull, the crystal skull vibrated violently, as if it was threatened by something, and more powerful spiritual fluctuations erupted, some of which rushed straight towards Richard's consciousness.

This!

Richard was startled, and while blocking with his own spiritual power, he quickly retreated.

But the next moment, something strange happened, and Richard found that his consciousness seemed to be bound by some force, and he couldn't retreat. Under the influence of an invisible force, his consciousness body was constantly drawn closer to the crystal skull on the altar.

Three meters, two and a half meters, two meters!

Stronger and stronger mental fluctuations kept coming, trying to erode consciousness, and Richard resisted with all his might. After half a ring, I found that it was not a way to go on like this, and I had to use the transparent belt on the back of my neck to return to the flesh as soon as my mind moved, but the method that I usually tried and tested was suppressed at this moment.

Richard could clearly feel a strong force coming from the transparent band on the back of his neck, trying to pull the consciousness body towards the back, but the crystal skull also emitted a stronger force and continued to pull towards the top of the altar.

Two diametrically opposed forces, like a tug-of-war, competed for the consciousness body in the middle, and bursts of pain came out as if they were being torn.

This can't go on like this!

Richard thought in his heart, and the next moment he deliberately slowed down the power of the transparent band, allowing his entire consciousness to slide towards the top of the altar.

Two meters, one and a half meters, one meter!

The corrosive mental fluctuations were stronger, and Richard could feel the bloodthirsty, angry thoughts constantly trying to control him, but at the same time, the pulling force eased slightly.

Now is the time!

Richard concentrated his mental strength, and controlled the transparent tape to pull it backwards with all his might, and his consciousness all became one thought: return to the body, return to the body, return to the body!

Brush!

An unprecedented force descended and enveloped the conscious body.

At this moment, the crystal skull seemed to be enraged, and it burst out with super spiritual fluctuations.

"Bang!"

The next moment, the spirit fluctuation of the crystal skull hit the surface of the consciousness body fiercely, and was blocked by the powerful force that descended, and then bounced back strongly.

With a "click", a slight crack appeared on the surface of the perfect crystal skull, and the sound of a ghost crying wolf howled came from inside, and the entire altar began to tremble, showing signs of cracking, and the binding force acting on the consciousness body disappeared instantly.

The transparent band behind him finally worked, and the consciousness body was jerked out of the mountain, and Richard felt like he had fallen into a wormhole. One second it was still in the air outside the mountain, and the next moment it directly crossed space and time, instantly appeared in the room in the ancient castle, and then fell out and into the flesh.

The change was so rapid that there was almost no reaction, and the moment it returned to the physical body, the consciousness body maintained an extremely high speed of movement, and then suddenly stopped. A force similar to inertia erupted, and as soon as Richard, who was sitting cross-legged on the wooden bed, opened his eyes, the whole person fell uncontrollably to the ground.

"Bang!"

He fell to the ground hard, and the pain spread, and then Richard realized how bad the situation was.

Originally, it was just a conscious body to explore the mountain, but at this moment, the body seemed to have been mortally wounded, with uncontrollable bleeding and blood in the nose and mouth, and the whole body seemed to be falling apart, and there was no place where it didn't hurt.

Of course, this is not the most important thing, the most important thing is that the heart in the chest cavity, in a calm state, beats uncontrollably at high speed, with a heart rate close to 200.

"Knock knock knock!"

At this moment, Richard could clearly feel the tightness in his chest, the swelling of his neck, the blackness in front of his eyes, and then dizziness. The body is unable to stand up at all because of fatigue, and if it continues like this, it is likely to lead to fainting and death.

This!
