Lei followed Hepburn's gaze and looked into the open door. Behind the door was a stone road suspended in the darkness, extending to the bottom of a gray tower.

This reminded him of what Hepburn said before his death, and what he learned from Posia that Hepburn had pursued throughout his life, the tower of Paumos, the legendary sacred object of the Eling Dynasty.

But isn't that a false saying that has been falsified?

Lei walked forward, and the moment he stepped onto the stone slab, the emerald door behind him slowly closed and disappeared into the darkness like a shadow.

Standing at the starting point of the stone road suspended in the vast darkness, rocks, ruins, collapsed buildings, and gray moths flew past. He raised his feet and walked forward. The stone road seemed to be crumbling at his feet, but in fact it was very stable. In less than half a minute, he arrived at the end of the stone road.

Only then did he realize that the entire tower was dilapidated, and the tower body was covered with holes. It was a miracle that it could hold on to not collapse.

The entire tower base is visually measured to be nearly 100 meters in diameter, with thick and short stone pillars surrounding the edges. The tower gate is the most complete place and is a semicircular arch dome-shaped design. The relief on the left half of the gate represents five star bodies of five types of metals, and the right half is embossed with symbols such as earth, water, fire and wind. The pallet of a scale is located at the bottom of the tower gates on both sides, and the entire lintel forms the cross arm of the scale.

The meaning of the pattern on this door is obvious.

"The conversion of matter and energy?"

As soon as Lei had this idea, the door blew up and opened to both sides.

An ancient breath came to my face, and inside the door was a dark hall with only a faint light in the center.

Thunder walked over, and the sound of footsteps echoed in the empty hall.

As he approached, he saw eleven stone statues holding oil lamps in the middle of the hall. The wicks in the oil lamp were lying quietly, still intact.

The stone statue surrounds a jade slab placed on the stone platform, emitting a faint green light.

“This is the end.”

Lei Jue felt something and took off the slab with both hands.

In an instant, the last trace of spiritual light on his soul was suddenly pulled away and sank into the stone slab.

Thunder's soul seemed to be decomposed in an instant, but was instantly reconstructed, emitting an unprecedented green glow.

A line of words suddenly appeared in Lei's mind.

"One means everything, everything is born from one."

A line of words suddenly appeared in Lei's mind. At this time, the jade slab floated up from his arms, hovered in the air, exiled the darkness, and illuminated the entire palace.

With the luster of jade, Lei finally got a glimpse of the whole hall. The hall area was close to a playground of about 3,000 square meters, and the ground was covered with gray stone bricks. Apart from the twelve stone statues holding lamps beside him, the whole hall was empty...

Under the ubiquitous glow of jade, Thunder's soul is as warm as a baby returning to the mother's fetus.

"This is my soul shelter."

Lei looked down.

His soul was originally light green, and his state was between flames and smoke, and it was unstable. However, after being reconstructed by the jade slab just now, it became much solidified. Although it was not clear about the specific meaning of this change, it was obviously a positive change.

Thinking that his body was still asleep, Lei did not intend to continue exploring the mystery of the soul and the spiritual world.

“How to get out?”

He looked up at the jade slab, imagining the return of the soul to the body.

...

Lei opened his eyes.

The orange light of the gas lamp is still stable.

Although he had left the spiritual world, he could still feel the existence of the jade slab, as if it was part of his soul.

As long as he wants, he can use the jade slab as the coordinates to re-enter the soul site at any time without having to re-pass the path of sublimation.

Moran was writing at the desk beside the table, and the pen stroked across the paper, making a rustling sound.

Lei looked out the window, it was still late at night.

He has not had a rest for dozens of hours in a row, but now he is in high spirits.

The mouse in the basement crawled past, and a newspaper on the street was blown away, and various sounds were heard in the ears, and the brain was able to process these sharp increases of information with ease.

This feels very wonderful, just like a person who has been myopic for many years finally put on glasses, and everything has not changed, but he feels like he has opened the door to a new world.

Until now, he successfully completed the sublimation of his soul through the Moonlight Path, possessed the soul site, and finally solved the deadly trouble. The biggest motivation that prompted him to come into contact with taboos is no longer there. But now, this novel power stimulates him again, making him want to get in touch with taboos more deeply.

Exploring the unknown and pursuing strength is a desire engraved in a man's bones.

At this moment, when he heard the movement, Moran put down his pen and looked back at the contemplative thunder.

"It seems that you have completed the sublimation, do you feel different?"

“My perception is much more acute.”

"Oh, it seems that you have gained extraordinary spiritual powers!"

"Mental ability?"

"Yes, you should have experienced it. A reconstruction should occur when your soul is sublimated. This will give you extraordinary abilities. Some people are proficient in animal languages, some people can control elements, and some people can see some strange lines... These abilities are diverse, generally depending on your sublimation direction."

"I understand." Lei remembered Moran's words. The mysterious knowledge recorded in the Road of Yuezhao was pitifully small. "Does my extraordinary ability be keen perception?" He carefully recalled his feelings just now.

Moran continued: "No, it's not that simple. Generally speaking, becoming keen in perception is only part of the benefit of soul sublimation. The soul that has just completed sublimation is not stable, and you still need some guidance and adaptation to fully discover the qualities of your abilities."

“What should I do.”

"It depends on the type of your ability. I once had a friend who did not awaken for half a year after sublimation. It was not until he accidentally broke a finger that he realized that his ability was the regeneration of the limbs." Moran showed a gloating look and said seriously: "But if your ability is indeed related to the spirit, then awakening is not very troublesome. For the ability related to the spirit, you usually only need to make a real alchemy attempt to perceive its characteristics."

He added: "Of course, this is just an attempt, and we cannot fully confirm whether your ability is related to the spirit. But even if the attempt fails, you will not lose anything. In any case, you will eventually learn real alchemy."

"Real alchemy?"

"Yes, real alchemy."

...

Moran Book House Basement.

There is a gas lamp on each of the four walls, which casts even and stable light into the center of the basement.

A huge desktop filled with various instruments, potions, tools, manuscripts and books.

“As a beginner, one of the most basic knowledge you need to know is what alchemy is.”

"Generally speaking, the role of alchemy is to facilitate the conversion between matter and energy, but it is limited to the superficial world level."

"But for the extraordinary, the span of alchemy will be elevated between the two worlds."

In front of the laboratory bench, Moran explained in an orderly manner, and at the same time laid papyrus on the table, taking out various tools and potions such as white sage, graphite powder, alcohol lamps, etc.

Lei listened carefully and summarized: "In other words, we can exchange matter and energy in the world through alchemy?"

"Yes, that's it." Moran nodded: "When you exchange material things between the two worlds, your soul will be constantly refined and eventually become purer than gold. This is why all spiritual practitioners study alchemy."

"The spiritual matter that is exchanged usually has strange abilities. You can obtain power and speed far beyond ordinary people with some spiritual potion, or ability that can never be remembered, or even control elements... These are the mysteries of alchemy."

“Sounds tempting.”

"It's normal for human nature."

Moran picked up a piece of papyrus, which was a pattern of a base, contract cipher text and symbols.

"This is a basic formation, which is designed to facilitate the exchange between the steel in the world and the Ghirgy in the world."

"What is the difference between Gerbert and the iron in the world?"

Ray took the papyrus.

"In the world of the world, Gertiate is very sensitive to substances from the spiritual world. It can usually be used as amulets to detect evil thoughts and can also be used to identify extraordinary items. However, in essence, it is not much different from ordinary steel, so this formation is also very simple, which is just suitable for newbies like you. Let's start by mixing potions..."

...

Ten minutes passed.

...

"The smoked graphite powder of white sage, added with a small amount of pure white crystal powder, is a simple spiritual medium that can be used to draw and refine into a formation."

"The refining array serves as a beacon and contract at the same time, which can help alchemists communicate to the spiritual world, position a certain substance and facilitate exchanges."

"Start, draw the refining array, remember not to relax the guidance of soul power at all times."

In front of the laboratory bench, Moran patiently guided him.

Lei held a quill with an airbag, sucked the graphite powder, and then drew the array picture on papyrus.

The base of the array diagram is a complete circle.

The circle is the beginning and the end point, which means that the cycle remains unchanged, is not subject to interference, and can also resist interference. It is the most basic refining matrix base.

Then he drew the hexagrams within the circumference as a symbol of energy.

Draw the Eye of Omniscience in the Center as a notarization of the contract.

Write the contract cipher text evolved from the ancient Elying language.

Lei's sheathed steel short knife was placed in the center of the formation.

The hexagon of the hexagram is filled with the symbol of matter.

A spear and shield symbolizing iron.
