At this moment, Qi Jiuxiao and the five of them flashed out without even needing Li Yichen to greet them.

Although they were already a little tired from the attack just now, everyone knew that if they missed this opportunity in front of them, they didn't know when they would be able to force out the sand core next time.

And once they can't contain the sand core, they will be greeted by a new round of endless attacks.

"I shouldn't be able to run away!" Li Yichen said with full confidence at this time.

Although the sand beast is extremely strong, but in terms of pure combat effectiveness, it is estimated that anyone present has the certainty of retreating, it is difficult to face the sand beast, and the entire desert is his battlefield, and if he can't attack the sand core, then the battle will never end, so when many warriors face the sand beast, they are not killed, but exhausted to death.

Now that the sand core was forced by Li Yichen to show his true body, it was naturally impossible for them to miss such an opportunity.

However, Li Yichen obviously didn't intend to give them another chance to play, and his ten fingers rolled between his words, forming one after another weird-looking seals, only to see that the crimson array that filled the entire heaven and earth quickly converged.

Just like saying that there was still a gap in the previous formation net, then under the current contraction, the formation network can no longer be called a net, but becomes a ball that traps the sand core in it, and then between Li Yichen's deep cry, the ball instantly turned into a scorching flame.

The fire condensed by the six Venerable Rank Formations, not to mention the sand core trapped in it, even Qi Jiuxiao and the others, who were originally going to contain the sand core, felt that their whole body was hot in this high temperature, and even if they ran the technique, they couldn't completely resist this scorching heat, and they continued to fly away.

At this time, as if he felt that his life was threatened, the sand core in the center of the flame also emitted a piercing scream.

The whistling sound of this scream piercing through the flames seemed to directly attack everyone's spirits without passing through everyone's hearing, and just when everyone's hearts were slightly relaxed, the surrounding sea of sand became violent again.

Countless winds and sand were like sea water, setting off wave after wave, and the troops divided all the way, attacking Li Yichen and the flame in the center.

However, Qi Jiuxiao and the others are all people who have been in battle for a long time, and at this time they all understand that the key to victory or defeat at the moment lies in Li Yichen, as long as Li Yichen can solve the sand core, all problems will be solved.

"Brother Chen, don't worry about us!" Qi Jiuxiao shouted loudly, and the Golden Sword Nine Tricks once again urged without reservation, and at the same time, the other four people also made their best moves.

They knew that this was the last fatal blow of the sand beast, as long as they resisted the past, with the power of Li Yichen's burst of fire, they could definitely refine the sand core completely, and then all the dangers would disappear with it.

"You dare to be presumptuous!" However, since Li Yichen had completely spent more than ten breaths before to complete the formation in an unprotected state, how could it be so easy to dissolve.

As soon as the cheers stopped, a flame jumped up from the ground, instantly swallowing the impossible sea of sand in it, and suddenly in the sea of fire, red and earth yellow were intertwined, and in countless crackling sounds, red and yellow continued to alternate.

Under the original state of equal division, with the addition of Qi Jiuxiao and others, the sand and dust in the sky were constantly shattered and disappeared, and this was the reason why Qi Jiuxiao had scruples about Li Yichen's fire and did not dare to get too close.

And as time passed, the sand core in the flames seemed to be constantly losing power, not only the screaming sound was getting weaker and weaker, but even the attack of the surrounding sand and dust was also greatly reduced, and in less than a quarter of an hour, except for a red flame enveloping the entire earth, there was no sand and dust at all.

"Solved?" Seeing this, Qi Jiuxiao said with joy on his face.

"This guy is very tenacious, you recover your spiritual power first, and I will refine him slowly!" Li Yichen said immediately.

Now that the threat of the sand beast has been lifted, but in Qingyun Peak, no one knows what kind of danger they may face next, at this time, it is naturally particularly important to maintain the best condition, and the sand core is in the flames, Li Yichen is also sure that it will be completely refined, and all that is needed now is time.

"Good ......"

Qi Jiuxiao and the others naturally knew the situation in front of them, and immediately sat down and recovered, while Li Yichen's spiritual tips on his hands were still constantly changing at this time.

However, fortunately, everyone else had entered the cultivation state, otherwise if they looked closely, they would definitely find that what Li Yichen had changed at this time was not the formation technique, but the pill technique!

Li Yichen is alchemy!

In fact, after completing the six-step formation, the links of the six supreme formations had already blocked the entire heaven and earth, not only the performance of the desert, but even the dozens of zhang underground were under Li Yichen's control.

Because Qi Jiuxiao's previous attack did not expose the sand core, Li Yichen had already guessed that the sand core might hide itself underground, so Li Yichen would set up a space confinement array.

In fact, the sand core was indeed underground, and Qi Jiuxiao could only see Li Yichen's formation attack before, but they didn't know that in the underground of the desert, Li Yichen's formation was still constantly attacking the sand core.

Although the sand core is not as intelligent as humans, it also has intelligence, and after feeling the aura of danger, the first reaction is to flee quickly.

It's just that the sand and dust that was manifested at that time was constantly destroyed by Li Yichen's formation, which weakened the sand core's feelings about the outside world, so they desperately escaped but became self-defeating.

And Li Yichen's six formations were superimposed, and the previous array network was just to force out the true body of the sand core, and the last flame nuclear burning array was the real killer weapon, that is, the flames transformed by the formation behind it.

Originally, everything was in Li Yichen's plan, and even the final desperate counterattack of the sand core was within Li Yichen's expectations, but Li Yichen finally found that he still underestimated the hardness of the sand core.

Under the continuous scorching flames that were enough to refine the supreme rank medicinal materials, the sand core was now only suppressed to the point that it was completely connected to the outside world, but its performance was like an incomparably hard rock, and no matter how much Li Yichen urged the power of the formation, he could not refine it.

At this time, although the sand core has lost the power to resist, if Li Yichen can't completely refine it, then once he breaks through Li Yichen's flames, all the previous efforts of everyone will also be in vain.

When he realized that the ordinary array refining method was no longer helpless, Li Yichen suddenly had a thought in his heart to refine the sand core again by alchemy.

Danhuo!

Its incineration ability was not comparable to ordinary array flames, and when Li Yichen found that the effect was still insignificant, he even began to inject Heavenly Dao power into the flames.

With the injection of Heavenly Dao power, the sand core was finally no longer as unmoved as before, but the speed at which it was refined was still very slow, according to Li Yichen's guess, if it was refined at this pace, it was estimated that it would not be possible to refine it in three or five months.

And with Li Yichen's current ability, even if he eats the elixir that replenishes spiritual power with him on his body, it is impossible to support his refining at this strength for three or five months, and if his firepower is weakened, Li Yichen, who has never been in contact with the sand core, does not dare to guarantee that this guy will not break out of the predicament.

This is also why Li Yichen wants to let Qi Jiuxiao and them quickly recover their spiritual power, not only to prevent sudden accidents, but also to leave a way back for himself to be unable to refine the sand core.

Melting Potions!

Suddenly, a flash of inspiration flashed in Li Yichen's mind!

Although if there is an alchemy furnace, it is only a matter of time before refining those medicinal materials, but there are still alchemists who have explored a set of melting techniques in order to save time.

After softening the herbs with the molten herbs as a guide, the characteristics of the herbs are fundamentally revealed, supplemented by continuous herbs, to neutralize their solidity and achieve a method of rapid refining of the herbs.

Although Li Yichen didn't know if such a method would be effective for the sand core at this time, for a real alchemist, everything in the world could be alchemy, and Li Yichen still decided to give it a try.

Molten herbs are the most common medicinal materials, and they are also essential for every alchemist, and Li Yichen is naturally no exception.

As the two molten herbs were thrown into the flames, Li Yichen found that after the liquid of the molten herbs was stained on the sand core, the appearance of the sand core began to become soft, and his face was immediately happy, and he began to sense the essential attributes of the sand core.

The art of melting medicine, although it is said to be an alchemy technique, is actually more like a formula.

Different medicinal materials have different properties, and the melting herb is just a medicinal introduction, so that the medicine village softens and reveals its true attributes, as for how to refine it quickly, it requires alchemists and even different needs to add different medicinal materials, and as for what medicinal materials to add and what kind of weight to add, it depends on the comprehension and understanding of the Dan Dao by each alchemist.

Therefore, after Li Yichen sensed the attributes of the sand core, he secretly deduced it in his heart, and then began to slowly add various medicinal materials.

However, the only good thing is that Li Yichen at this time does not want to refine any pills, his purpose is only to completely refine the sand core, so that after a lot of scruples, Li Yichen can completely let go of his hands and feet.

Gradually, Li Yichen found that in the process of refining, the changes in the attributes of the sand core were completely beyond his expectations, which also made Li Yichen seem to see the Dan Dao beyond what he knew.

Unconsciously, Li Yichen's whole mind seemed to be completely immersed in the mystery of the Dan Dao, and even at this time he had forgotten that his original purpose was only to refine the Dan Sand Core, and at this time, the thoughts he still retained seemed to only exist in the unknown exploration of the Dan Dao.

"This ...... Is this refining the sand core or alchemy?" The crackling sound here naturally woke up Qi Jiuxiao and the others, watching Li Yichen sometimes throw some medicinal materials into the flames, and several people looked at Li Yichen with blank expressions......
