"Haha, it's a big profit, this set of combination magic weapons is simply a tailor-made equipment for me for us immortal cultivators!"

Li Ang was ecstatic in his heart, meditated cross-legged on the spot, silently decided the law, and urged the Vajra Demon Circle.

In an instant, the nine rings on the iron ball gradually lit up, exuding an earth-shattering ferocious aura!

A terrible roar came from within the iron ball, like a beast struggling to die, and it made people's hearts chill.

In an instant, the surface of the iron ball suddenly bloomed with a dazzling blue-purple light, condensing into a monstrous beast, roaring and roaring and rushing towards Li Ang, baring its teeth and dancing its claws!

"Humph! Insect carving skills! ”

Li Ang snorted coldly, fearless, and killed the past head-on!

He stretched his limbs, concentrated his spiritual power between his fists and feet, and fought with the monstrous beast, and a series of crackling crashes continued to explode, like a torrential rain, dense!

"Roaring ......"

The strange roar kept echoing, shaking Li Ang's internal organs for a while.

The two fought for ten minutes, and the giant beast finally couldn't bear it anymore, and fell to the ground with a bang, completely killed.

"That's it!" ，

Leon breathed a sigh of relief and wiped the sweat from his forehead.

Just when he was about to take the Vajra Demon Ring back to the storage ring, suddenly, a change occurred!

That giant Vajra Demon Circle turned into a spark in the sky, and it actually burned in mid-air!

Leon was so frightened that he almost jumped up, if this thing burned out, then he would lose all his money!

"What's going on?"

Li Ang quickly took out a syringe, inserted it into his arm, and injected a sedative to stabilize his mood.

The effect of the tranquilizer worked, and Leon's vision cleared a lot, and he saw that the burning metal powder was not really burning.

Instead, it converged into a vague silhouette in mid-air, and it was a burly body more than three meters tall, wearing golden armor, with six wings growing on its back, and its face was shrouded in mist, and it was not clear what it looked like.

"This is the machine spirit of the Vajra Demon Circle? Looks...... Seems to be dead? ”

Leon stared at the phantom fluttering in mid-air, his brow furrowed.

At this moment, a text flashed out of thin air and appeared in front of his eyes.

[Congratulations, you have obtained a special reward - the initial refining cheats of the Vajra Demon Circle, do you want to receive it?] 】

Li Ang thought for a moment and clicked "yes".

In an instant, the phantom dissipated, and the iron ball in Li Ang's hand suddenly disintegrated into countless parts, and fell to the ground one after another.

In the center of the pile of scrap metal floated a thumb-sized orb.

The beads are engraved with intricate and mysterious charms, revealing the charm of ancient vicissitudes.

Li Ang reached out and grabbed it in his hand, and suddenly felt a cold feeling surging through his body, as if he was in an ice cellar.

The next moment, the bead melted into Leon's body, and he felt an extra refining manual in his mind.

"King Kong Demon Circle".

"Original...... This is the refining method of the Vajra Demon Circle? ”

Leon muttered to himself and flipped through the manual.

This manual is extremely obscure, and some of the key words are so vague that it is impossible to fully understand.

However, after all, Li Ang also received a higher education and had a wealth of knowledge, and he quickly mastered the essence of this secret tome!

First of all, the basic refining of the Vajra Demon Circle is very cumbersome, and every detail needs to be treated rigorously, and there is no room for sloppiness!

Also, you have to use special materials and secret techniques, otherwise you will fall short!

"Huh? What kind of material is this......"

Leon rummaged through the manual and suddenly found a palm-sized piece of red jade, crystal clear, emitting a faint brilliance, as bright as red coral.

It's just that the red jade is transparent and has no ornamentation, just like the most ordinary jade.

But a closer look at its exterior reveals a magical aesthetic.

Leon tried to cover the palm of his hand over the red jade, but felt a burning heat, as if he had been burned by a soldering iron.

"Huh?"

His face changed slightly, and he immediately withdrew his right hand, and the red jade regained its composure, turning into the size of a palm again.

"What the hell is this red jade, how can it be so weird?"

Li Ang frowned and groaned: "According to what is said in the book, the core material of the Vajra Demon Circle is this red jade stone, if this red jade stone is lost, I'm afraid I won't be able to refine the Vajra Demon Circle, right?" ”

"In that case...... You have to take a chance! ”

Li Ang took a deep breath, closed his eyes, adjusted his mentality, and tried to focus on the ruby stone, wanting to keep it for himself!

As time passed, Leon gradually forgot about his surroundings and focused his attention on the ruby stone.

He could feel the temperature of the red jade getting higher and higher, almost boiling, as if it would burst at any moment!

"With such a high temperature, if it is forcibly refined, it will definitely damage the red jade and cause backlash!"

Li Ang gritted his teeth, resisted the coercion of the red jade, and persevered.

Gradually, the temperature of the ruby stone decreases and eventually returns to its normal state.

When Leon opened his eyes, he found that the red jade had disappeared and he had received it into the storage ring.

"Whew, swoop."

Leon gasped a few times, feeling extremely tired.

Although his strength is strong enough, he can't stand the temperature of this thing is too high, and it is hundreds of times higher in an instant, and he can't bear it at all.

"Still, it's done. In the future, as long as I refine this red jade stone, I will be able to have the Vajra Demon Circle. ”

Li Ang smiled with satisfaction, "As long as I am given a few years, I can cultivate a martial artist with superior combat effectiveness!" ”

At this moment, the system interface jumps and a new prompt message appears.

【Ding Dong!】 Congratulations to the host for completing the main quest and getting a special reward - obtaining the refining secret of the 'King Kong Demon Circle'. 】

[Refining method: Use blood as a guide, supplemented by spiritual power, and build a unique Vajra Demon Circle based on the Vajra Demon Circle. 】

[Note: This method is for reference only and cannot be used as a standard answer, please use it with caution!] 】

Li Ang was stunned: "I'm wiping?" ”

He never expected that the Vajra Demon Circle could still be refined like this!

Isn't this equivalent to refining a rope yourself?

Li Ang couldn't laugh or cry, what kind of main quest is this!

However, he didn't have enough energy to refine this thing right now, and he didn't bother to waste time researching it, so he just put it in the storage ring as a temporary benefit and pondered it later.

Later, Li Ang checked again, and after confirming that it was correct, he cleaned up the remaining clutter and walked out of the Scripture Pavilion.

……

Night.

A secluded mountain forest.

Leon sat cross-legged on a branch to rest.

He had killed a total of more than twenty demon wolves today, as well as four dark wizards, and three zombies, including a silver-tier demon!

This hunt is very rewarding!

"There are so many demon pills, it should be able to exchange a lot of money."

Li Ang took out a purple demon wolf king's demon pill from his arms, weighed it and said, "But...... The demon pill can only be swallowed directly, and it is not suitable for equipment. ”
