The sudden upheaval fluctuations in the horn apparatus surprised Yan Fall, and he hurriedly used his mental power to stabilize the restlessness, and secretly wondered in his heart why he used those seven changes to make the fusion of the potions produce such a big reaction.

However, if they didn't continue to fuse, even if Yanfall forcibly curbed the spread of medicinal power, it was very likely that these medicinal materials would destroy each other one by one between the collisions, and it would still mean that the potion refining would fail.

Gritting his teeth, Yan Yan couldn't take care of it too much, and now there was only one way forward, and the back road had been sealed.

The seven changes were applied to the spiritual power, and the strong spiritual power of Yanfall suddenly turned into dozens of rays of light, each of which was like a chain wrapped around a medicinal material, without the suppression of Yanfall, these medicinal materials once again rioted, and Yanfall ignored this, concentrating and holding his breath to put all his mind on controlling the spiritual power.

Gradually, a sense of enlightenment rose from the bottom of his heart, and this sudden feeling made Yanfall a little inexplicable.

"My spiritual power has just reached the peak of the fourth order, is it possible that I will break through the fifth order in such two days?"

Thinking of this, Yan Cheng's heart jumped, and he quickly denied his idea, joking, if he cultivated so fast, it would be too shocking.

But the spiritual power was indeed steadily growing, rushing towards the fifth-order calm.

The spiritual storm swept through the entire stone house, and the lamps on the walls of the room also began to sway with the appearance of this spiritual storm, as if they would be extinguished in the next moment.

The black glow on the horn became more and more abundant, and the body of the instrument also trembled.

A hint of uneasiness suddenly appeared in Yan Yan's heart, "This horn weapon ...... It's not going to explode, is it?"

As if to fulfill what Yanfall thought, a crack on the horn suddenly appeared, and when he saw this crack, Yanfall couldn't wait to slap himself, this crow's mouth was simply amazing......

Flamefall's knowledge of the pharmacist is limited to the method of refining the potion and the method of fusion, but he does not know some of the taboos of the pharmacist.

The first taboo of pharmacists: "In the refining of pharmacists, it is most taboo to use different methods of refining, once this happens, the fusion of the medicine will appear extremely unstable, if this happens, then it means that the refining of the medicine has failed......"

Yan Fall didn't know this, so after Yun Zi'er's spirit was exhausted, he continued to fuse the potion with his own fusion method, and the two completely different techniques were applied to the ice potion at the same time, and this energy riot was caused in this way.

Seeing that the cracks on the horn device were getting bigger and bigger, Yan Yan frowned, and quickly thought about countermeasures.

Now that he was almost in a process of slow death, once the horn organ shattered, the cold ice potion would 100% fail, and Yan Fall didn't think that he could stabilize the medicinal properties that were escaping everywhere without the horn device.

In other words, this horn must not be broken!

Thinking of this, Yan Fall carefully sensed the situation of the fusion of the elixir, and suddenly his expression was happy, in Yan Fall's perception, he applied those seven changes to his spiritual power, which actually added a few points to the fusion of the cold ice elixir, as long as he came a few more times, it was very likely that the cold ice elixir would be successfully fused.

But...... How many times can the horner withstand it?

After using his own method to fuse, the medicinal power began to disperse, and the horn weapon was gradually broken because of the medicinal power of this riot, although Yan Cheng locked these medicinal powers with his spiritual power, but after all, this qiē was carried out in the horn vessel, how strong Yan Fall's spiritual power was, and it caused damage to the horn apparatus in the constant friction with the horn apparatus.

Thinking of this, two words came to Yan Yan's mind: "Compress." ”

If you let your spiritual power wrap the medicinal power without touching the horn device, not only can the medicine be fused, but the horn device will not be shattered so quickly.

But compressing mental power will definitely cause pain, and as for how far the pain will be, Yanfall doesn't know, but for now this is the only way.

Thinking of this, Yanfall no longer hesitated, and controlled the spiritual power to compress the center of the horn device, and at the same time, the seven changes were used again into the spiritual power to start the fusion of the potion.

A cone pain made Yan Fall's brows furrow, he didn't expect that compressing his mental power would produce such a great pain, that feeling was as if he had been cut by someone with a knife, even with Yan Fall's patience, this pain still made him sweat.

It's just pain, isn't there much Yanfall has experienced?

Half an hour passed quietly, but for Yanfall, every minute was like a year, and the pain from the depths of his soul made Yanfall's whole body tremble faintly.

The only good news is that under the control of Yanfall's spiritual power, the potions are fused in an orderly manner, but it is conceivable that while enduring such pain, he still has to use his mental power to perform those seven changes, which is quite a severe test for Yanfall.

There will always be a reward for the effort, and all the medicinal materials were finally fused, and a pool of liquid like blue crystal slowly took shape under the wrapping of Yanfall's spiritual power.

A smile appeared on Yan Fall's pale face, and while bearing the pain, he had to fuse the potion, the consumption of spiritual power was too huge, and the fatigue that had not appeared for a long time came to the bottom of his heart, and his consciousness was slightly relaxed, and a spiritual force easily destroyed the horn weapon, and at the same time, Yan Fall used his last strength to fill the pool of liquid into the jade bottle.

The spirit was completely relaxed, Yan Cheng held the jade bottle in his hand, and fell to the ground, before he fell unconscious, there was still a smile on the corner of Yan Cheng's mouth, this time, he did it.

Although it is not a real refining of a bottle of potion, most of this cold ice elixir was completed by Yanfall himself, a kid who has not been a beginner in potion for a long time, and he refined the potion the next day, and it is also an extremely difficult potion to refine in the second order, which will frighten many people if it is said.

......

I don't know how long it took.

"Hmm......"

Yun Zi'er opened her eyes and saw a dim stone wall, and the tingling pain in her brain made Yun Zi'er frown slightly, and then she suddenly thought of something, struggling to do it, and when she supported the ground with her hand, she only felt a pain in her fingertips, and frowned, but found a pitch-black fragment cutting her finger.

With a shrunk pupil, Yun Zi'er ignored the scratched fingers and picked up the debris on the ground, and the familiar feeling made two lines of tears flow from the corners of Yun Zi'er's eyes.

Yun Zi'er, who had refined potions hundreds of times, how could she not recognize this horn weapon that had been with her for several years?

It doesn't matter if the horn is destroyed, but the most important thing is that the destruction of the horn means that the Ice Elixir has failed......

Tears slipped silently, Yun Zi'er sat up, and at a glance saw Yan Fall lying on the side, Yan Fall's pale face made her slightly stunned, this is obviously a manifestation of excessive mental power consumption, how strong Yan Fall's spiritual power is Yun Zi'er knows, but now it is as strong as Yan Fall, and he has passed out due to excessive consumption, which shows how much effort he has put into refining the ice elixir.

A feeling called touching spread from the bottom of Yun Zi'er's heart, she and Yan Fall did not owe each other, but Yan Fall passed out in order to help her refine the potion, although it was said that she failed in the end, but Yun Zi'er already had a place in Yan Fall's heart.

Sitting beside Yan Cheng gently, Yun Zi'er looked at Yan Cheng's delicate face with soft eyes, and was actually intoxicated for a while.
