Shan Boyang's studio has an enclosed room, which is where he usually makes instruments.

Fang Tian was the only one in the empty space, sitting upright on the ground, and the stone axe and the soul of the refining weapon were all placed in front of him.

His own stone axe was an artifact that had lost its divine soul and fell into a deep sleep, and Fang Tian had no doubt about this.

The stone axe had been bound to Fang Tian's soul, it could be said that the two had merged into one, and Fang Tian could feel it.

Then the stone axe itself can also produce spiritual power, and it will also actively regulate the spiritual power in Fang Tian's body, indicating that it has a kind of consciousness.

The most important thing is that it can also teach Fang Tian techniques, and all of them are super techniques.

Teacher Shan Boyang's attainments in instrument research were unparalleled, according to the information Fang Tian learned from him.

The stone axe has all kinds of functions that no other weapon in the world can have, even the most top-level saint-level weapon.

Fang Tian firmly believes that it will definitely be the most important support in his growth.

"I'm going to help you advance!" Fang Tian said, stroking the stone axe.

The stone axe seemed to understand Fang Tian's words, and trembled slightly, and a faint white light appeared on its surface.

Weapon advancement is very simple, it is to integrate the soul of refining into the weapon, so that the two are perfectly fused.

But the actual operation is not simple at all, and there are three steps involved: soul refining, soul shaping, and fusion.

To put it bluntly, the soul of the refining weapon is the soul of the Warcraft, and it has manic energy from the Warcraft, which will repel other mediums.

Soul refining needs to be more cautious, that is, to suppress the demonic beast energy as a soul state through the spiritual energy of the human body, so that it will not be repelled from other mediums.

The soul has always been relatively fragile, even the soul of the monster is no exception, if the spiritual power used by a person is too strong, it may inspire the demon soul to resist, and the demon soul will be damaged.

Fortunately, Fang Tian was already a qualified spiritual martial artist, and he was very familiar with the control of spiritual power.

He first carefully released the soul of the refining weapon from the bottle, which was a crimson demonic beast soul, and it could be seen that there was a surging manic energy contained in it.

Slowly attaching the spiritual power, he smoothly used his spiritual power to gently wrap the soul of the demonic beast, and subtly condensed, without causing the energy fluctuations of the demon soul itself, and the soul refining was successful.

Soul shaping is a creative process, which is to shape a spirit core for a weapon. To put it simply, it is to put a virtual box in the weapon, and this box is used to hold the soul of the Warcraft, which is equivalent to the mind of the weapon, that is, the spiritual core.

The success rate of the spirit core is related to the maturity of the weapon's advancement, of course, Fang Tian's stone axe is already in the advanced maturity stage, so there will be no problem at all, Fang Tian has successfully shaped the spirit core for the stone axe.

However, the current spirit core is only an empty core, and the soul needs to be integrated into it to become a real spirit core.

The demon soul that had been condensed by spiritual power and the stone axe that had shaped the spirit core were all floating in front of Fang Tian.

The final step is fusion.

Under the control of Fang Tian's spiritual power, the demon soul and the stone axe slowly floated towards each other, and then began to make contact, and the demon soul gradually merged into the stone axe, closely combining with the spirit core.

Immediately after that, the entire stone axe began to shake violently.

A layer of crimson light overflowed from the spirit core, quickly spreading to the surface of the entire stone axe, and the stone axe's shaking became more and more intense.

Fang Tian frowned on the side, quietly staring at the stone axe trembling in the void, his face was very solemn.

Fang Tian knew that the stone axe was absorbing the essence energy of the demon soul at this time, and was trying to give birth to his own spirituality.

This process lasted about five minutes or so, and the situation of the stone axe finally changed.

A layer of pale white light, breaking through the crimson halo, slowly enveloped the entire stone axe.

And directly began to devour the crimson halo, the red halo became fainter and fainter, and gradually dissipated, while the white light became brighter and brighter.

When the red halo is completely gone, a golden halo appears on the surface of the white light.

This layer of golden halo closely echoed Fang Tian's spiritual power, which was exactly the power of his earth spirit.

"Succeeded?" Fang Tian blinked, secretly happy in his heart.

Rubbing his hands, Fang Tian held his hand on the stone axe.

The moment his hand touched the stone axe, an unprecedented sensation appeared.

An invisible strong aura fluctuation suddenly shot out in all directions, and everything in the room vibrated greatly, as if there was a strong wind blowing, and some objects on the table were blown messy, and even fell directly to the ground.

This powerful aura fluctuation had no effect on Fang Tian alone, holding the stone axe in his hand and not moving, only the gently swaying hair on the sides of his dark face could prove that this aura fluctuation did exist.

"Buzz ~~~~~"

The stone axe let out a low humming sound, like the roar of a demonic beast, although the sound was not loud, it hit Fang Tian's heart, and the sound shook the spiritual sea!

Immediately after that, a majestic power poured directly into Fang Tian's body through the hand holding the stone axe.

The hot blood in Fang Tian's body was tumbling, this was a feeling that he had never felt before, thick and full.

From the prestige, it can be judged that this is already a spirit-level weapon.

Mortal-level weapons themselves do not have real power, they often exert the power of holding the spiritual power of a warrior, or the power attached to foreign objects such as magic crystal gems.

This kind of power is estranged, flawed, and passive.

When it comes to spirit-level weapons, the power is generated by the weapon itself, and unlike the power attached to foreign objects, the power and the weapon itself are integrated, more thick and solid, and it is actively exerted by the weapon.

Because it has spirituality, the destructive power of the weapon is undoubtedly even greater.

Holding the stone axe in his hand, and waiting until the light on the stone axe slowly dissipated, Fang Tian could fully see the true face of the stone axe, with some slight changes.

Actually, nothing has changed overall, but if you look closely, you will see that there are some golden yellow lines on the outline of the entire stone axe.

This slight change did make Fang Tian a little disappointed, and he thought that there would be some big changes in his advanced spirit weapon, but this should be a proof of his earth spirit power attributes.

I remember that when I was competing in the martial arts examination before, my mind penetrated into it, and the stone axe directly transmitted the technique and engraved it in my mind.

I wonder if there will be new techniques after advancing to the spirit weapon?

It can't be wrong, nothing noticeably has changed on the surface, there must be a surprise inside.

This is mediocre on the outside, but there is something good on the inside!

Fang Tian couldn't help but feel a little excited.

Taking a deep breath, he sat down, his mind probed into it, and Fang Tian was quickly surprised to find that there was a void and dim space inside the stone axe.

It's dark, what's going on?

This space is very vast, and Fang Tian's mind turns into a virtual light and shadow portrait, floating in it as if he is in the boundless starry sky of the universe.

Although he felt strange, Fang Tian did not panic.

The virtual Fang Tian continued to explore and wander, and soon he noticed that there was some light.

He floated towards the light, and soon a stone tablet floated in the middle of nothingness.

The stele was as tall as an adult, black-brown in color, blending in with the dim surroundings and supposedly invisible, and it was the light from the words on it that made its outline appear.

The glowing words on it, Fang Tian could actually understand it.

"Open the mountain!"
