Chu Ling calculated it for a while, and quickly determined the treasures he needed.

What is a comprehensive magic weapon?

It has a series of functions such as protection, attack, spell, escape, road protection, etc., and can fight, carry and run. These pseudo-saints on the earth, due to the incomplete Dao system, the treasures refined into them often have a single function.

The Zilan Tang Knife only has the ability to attack, the Thunder Seal only has the power of spells, and the other Black God Armor, Four-Rank Lotus Terrace, etc., are all pure protection. There is no effect that Chu Ling thought of, with a treasure in his hand, and nothing else.

"The key is that if you only sacrifice one function, you can maximize your power. It's too difficult for these pseudo-saints on the earth to concentrate all their functions in one magic weapon. With their refining techniques, they may be able to do it if they advance another 10,000 years. ”

Chu Ling shook his head amusedly.

However, it was difficult for earth cultivators, but in Chu Ling's hands, it was very simple.

He didn't refine it before, but he didn't have the materials in his hands. finally got a pseudo-holy rib, and he accepted a few ghosts and gods, and reluctantly cultivated them into a divine flute. But the material of the Divine Flute is only a pseudo-holy rib, and those ghosts and gods are only half-step Spirit Venerables. It's very good to be able to get to this point.

"But with these artifact materials, it's different. What kind of treasure should I sacrifice and refine?"

Chu Ling's gaze swept over the alien artifacts, thinking happily in his heart.

Although these artifact materials are relatively rare, their attributes are completely different, such as the Heart of Light, the Feathers of Fire Beasts, the Spear of Thor, the Halberd of the Sea God, and so on...

"It's better to use the Thunder Seal as the core to refine a Five Elements Divine Seal. ”

Chu Ling's gaze finally fell on the thunder seal, and suddenly there was a flash of inspiration.

Chu Ling slapped his palm.

After deciding, Chu Lingxun began to refine and prepare.

He first ordered someone to deliver the news that he was going to retreat for a while. Then sealed the entrance to the treasure vault passage. This dark treasure house, located hundreds of meters underground, cannot be blown up by nuclear bombs, and is definitely the best place to retreat.

"To refine a spiritual weapon, you need the Emperor Saint True Fire, or even a stronger Divine Flame. But I have a fire, but I am not inferior to the true fire of the Emperor Saint. ”

Chu Ling said, sacrificing the thunder seal, and two golden flames quickly erupted from the pupils of his eyes. As soon as this golden flame burned the thunder seal, even with the material of a medium-grade spiritual weapon, it buzzed and roared.

But Chu Ling didn't stop at all, but continued to urge the golden pupils.

The brilliant flames, like two pillars of golden light, firmly enveloped the thunder seal in it. The spirit weapon has already given birth to a trace of spirituality, and can feel that it is about to be destroyed. But it is not a spirit treasure after all, and there is no machine spirit yet. Therefore, after being controlled by Chu Ling, he could only obediently be tempered by the flames.

One hour, two hours, three hours.

Slowly, the surface of the thunder seal began to melt gradually.

This statue is made of mysterious bronze, and the thunder seal with countless patterns is drawn on it, and gradually turns into a copper juice. Countless generations of Heavenly Masters, the various magic circles and thunder talismans that the pseudo-saints blessed on them were also gradually stripped out by Chu Ling.

Those magic circles were too rough, Chu Ling couldn't look down on them at all, and directly abandoned them. There was only the core thunder talisman, but it was left behind by Chu Ling, preparing to use it as the center to build the Five Elements Divine Seal at that time.

"Almost, it's time to add other materials. ”

Chu Ling beckoned.

A red light appeared in front of Chu Ling. In the glow, there is a tail feather like a long sword, this tail feather is half a meter long, the two sides are as sharp as a sword, and the emperor and saint god pattern are painted on it, red as fire, and a heat wave comes out of thin air.

Phoenix Feathers!

Legend has it that the great magician of the peninsula, after the death of his partner, a phoenix, finally obtained a tail feather with infinite power. It can unleash a heaven-shattering fire.

"Although this is not a real phoenix, it is just a spirit beast with a trace of phoenix blood, but it is barely enough. ”

Chu Ling said, pinching the magic technique, spewing out golden flames, and refining the feathers again.

True Dragon, Heavenly Phoenix, those are all existences comparable to the True Immortals of the Dao. The longevity is long, over a million years, and the powerful can even rival the Immortal Venerable. A feather can burn the earth to ashes, how can it be obtained by a mere pseudo-Saint Emperor Saint.

"Poof. ”

Although the phoenix feather is also a fire genus, it can't support it under the sacrifice of the golden pupil from the fire. I saw that the red light on its exterior gradually shrank, and it retreated under the golden divine flame, and finally its wings began to melt gradually.

However, although the material was melted, the Emperor Saint God pattern in the feather was retained by Chu Ling.

He was the top refining master, and his manipulation of the heat was unimaginable. Soon, two cyan and red balls of light appeared in the void.

But that's just the beginning.

"Poseidon Halberd. ”

"Earth giant heart. ”

"Immortal Golden Sword. ”

One by one, the treasures from the mythology of the earth were unceremoniously thrown into the golden flame by Chu Ling. These may be the treasures collected by the Dark Arbitration Department and even the Blood Ancestor for thousands of years, and they are almost the only artifacts left on the earth now. But Chu Ling didn't feel distressed at all, and one by one he was separated from the fire golden pupils and melted into juice.

Soon, seven or eight balls of light appeared in the void. Each orb of light is completely different in color, representing ancient artifacts.

"The materials are ready, and now the official sacrifice begins. ”

Chu Ling wiped his sweat.

Even with his cultivation at the peak of his Spirit Venerable, he released the golden divine flame for three days and three nights in a row, and he felt that he couldn't bear it, but Chu Ling knew that the real refining weapon had only started now.

"Five Elements God, listen to my orders, the thunder of the nine heavens gathers here!"

Chu Ling pinched the magic trick and punched out one magic seal after another.

The surging Five Elements Vitality within a radius of ten miles, as if ordered to do so, gradually poured into this underground treasure house from all directions. One after another, spells and magic circles gradually condensed in the void.

Each magic circle represents a certain function of the future magic weapon.

Generally, for a low-grade spiritual weapon, five magic circles or runes are sufficient. There are only ten medium-grade spiritual weapons. There are thirteen angels on the thirteen-note scale, which is already very powerful, and is known as killing gods.

But this time, Chu Ling's refining of the Five Elements Divine Seal required at least twenty-five magic arrays!

It's just shocking and appalling!

Once he said it, it was enough to shock the entire Earth Cultivation World. Even a stronger monk would be very troublesome here.

It is unimaginable that once this magic weapon is cultivated, the power will be so powerful!

"Boom!"

When Chu Ling was refining the 'Five Elements Divine Seal', a thunderbolt descended directly from the Nine Heavens and exploded over the Winter Palace, rolling thunder and trembling, and the sound spread for hundreds of miles. It was just on, and then, the second and third thunderbolts, came down one after another, and it was like a thundercloud in the sky, and the clouds were thick and surrounded by lightning.

Sun Kai and the others had already received Chu Ling's orders and did not panic.
