So Yu Feng stood aside, waiting for Senior Sister Yunxi to make a mistake.

I saw her urging the fire, and the red and bewitching fire instantly ignited the bottom of the alchemy furnace, and the sound of hunting began to slowly resound throughout the room.

After a while, a faint medicinal fragrance spreads, making people smell in a good mood.

But Yu Feng knew that the fragrance of the real Pei Yuan Dan should not be so faint, and it was obvious that Zuo Yunxi had failed to refine it again.

Sure enough, after half an hour of controlling the flame, this is the first furnace of elixir that belongs to today.

Seeing that the refining was completed, Zuo Yunxi hurriedly opened the alchemy furnace and took out the pills inside.

When I looked down, it was still black.

"Why did it fail again?"

Zuo Yunxi sighed and sat on the futon with some annoyance.

Yu Feng, who was pretending to be on duty next to him, saw that the time was almost ripe, so he slowly spoke.

"Senior sister, your alchemy has failed."

Zuo Yunxi heard someone ask a question and responded in a daze.

"Yes, I obviously controlled the proportion of medicinal materials very tightly, and even the order of the master's medicinal materials was the same, how could I fail."

Yu Feng smiled and said.

"Senior sister, why don't you want to think about whether the problem is on the tinder?"

"Tinder? How is it possible, this is impossible given by the master......"

At this time, Zuo Yunxi realized that it was a disciple on duty who was talking to him.

Alas, what could he understand.

"Forget it."

"I think that Senior Sister, your Danhuo control is a bit too hasty, which will cause the pill to mature ahead of schedule and miss the best time for refining."

"Huh?"

Zuo Yunxi originally planned to use the remaining Danhuo, and then try to refine a furnace of Peiyuan Dan, it doesn't matter if it succeeds or not, it's a big deal to be scolded again.

Unexpectedly, Yu Feng's words seemed to wake her up.

"I remember that the master seems to have said something similar, could it really be that there is a problem with my fire control?"

Zuo Yunxi held doubts, opened the Dan furnace again, and refined today's second furnace Pei Yuan Dan.

This is really worthy of being a disciple of the Academy, and the alchemy materials are thrown in one by one.

Now Yu Feng next to him sighed.

This time, when Zuo Yunxi was refining the pill again, he remembered what Yu Feng said, and deliberately controlled the fire.

Sure enough, the medicinal fragrance that burst out of the Dan furnace this time was much stronger than last time.

Zuo Yunxi opened the Dan furnace and saw that there were six Peiyuan Dans in a whole furnace, lying at the bottom of the furnace shiningly.

"I made it!"

Zuo Yunxi was overjoyed, he had been refining Pei Yuan Dan alone for three whole days, and he had not succeeded until today.

But it all seems to be thanks to ......

Zuo Yunxi only remembered Yu Feng at this time, so he glanced up and found that Yu Feng was carefully cleaning up the waste dregs he had just thrown away.

"You've studied alchemy before?"

Zuo Yunxi asked.

Although Yu Feng just said casually on the surface, it seemed like an unintentional move, and he happened to mention his alchemy by mistake.

But Zuo Yunxi knew that ordinary cultivators would not know the rhythm point of Danhuo at all.

What's more, he's just a handyman on duty.

"Senior sister has good eyesight, in fact, before I entered the Taiyi Taoist Sect, my father was also an alchemist, and I have been under the influence of his ears and eyes since I was a child, and I also know a little bit about fire control, so I saw that my senior sister failed, and guessed if there was a problem with fire control......"

Yu Feng's words seemed very sincere, and he said what he had thought of a long time ago.

When Zuo Yunxi heard this, he was instantly stunned.

"I see, no wonder you know how to control fire, you have contributed to the success of my refining this time, this Pei Yuan Dan will be given to you as a reward."

Zuo Yunxi smiled, as the senior sister of the Academy, she was one of the disciples who had the least shelf.

Yu Feng glanced at it, the quality and system reward were far behind, but on the surface, he still pretended to be surprised and didn't dare to accept it.

"It's just a gesture, and I'm just a handyman, I can't stand this, senior sister, you better keep it."

Yu Feng pretended to refuse, and then inadvertently pointed out that he was a handyman.

When Zuo Yunxi saw this, his eyes lit up, and he reacted.

The master had always asked her to find a handyman on duty to be a Dantong, but Zuo Yunxi always felt that there was no need to trouble others, and she could do it herself.

But it wasn't until today that she realized how important it was to have a Dan Tong by her side who knew the fundamentals of alchemy.

"In this way, from today onwards, you don't have to be on duty every day," Zuo Yunxi gave Pei Yuan Dan to Yu Feng and continued, "Come to me, be my Dantong, I will go to ask for someone tomorrow." ”

"Really, thank you, senior sister." Yu Feng took the pill homeopathically, although the quality of this white gift is not good, but don't do it in vain.

Zuo Yunxi threw Yu Feng another token engraved with his name, and gave a few instructions, asking him to clean up the mess here first, and by the way, familiarize himself with the environment of the school palace.

Then he hugged the remaining Pei Yuan Dan and walked out of the Dan room excitedly, probably looking for her master to invite merit.

[You found a mistake in Zuo Yunxi's refining of Pei Yuan Dan, and chose to watch first, and then point out the mistake, comprehending the basic Dan decision, Zuo Yunxi's favor +5]

Looking at Zuo Yunxi's departing back, Yu Feng suddenly felt a sense of guilt welling up in his heart.

This girl doesn't seem to be the same as other disciples, isn't it a little bad to fool her like this.

But the matter has come to this point, there is no turning back from the bow, at least this morning has not been in vain, this first step of the plan, can be regarded as a success.

Bang!

The flames in the Dan furnace made a sound, and only then did Yu Feng turn his attention to the Dan furnace.

The remaining flames were no longer enough to support refining Pei Yuan Dan again, but they couldn't just watch the fire go to waste.

Yu Feng smiled, swallowed the Pei Yuan Dan given to him by Zuo Yunxi, and activated the Red Fire Ghost Body to absorb the flames in the Dan furnace.

Originally, Yu Feng still felt that the remaining little flame was not worth the risk of using the Red Fire Ghost Body to absorb it, but after thinking about it, he finally adhered to the principle that no matter how small a mosquito is, it is also meat, and it accumulates a lot, and "reluctantly" devours it.

But what he didn't expect was that just absorbing such a little bit of Dan Fire would make him almost touch the door to break through the dual martial artist.

With the addition of the Red Fire Ghost Body, the entire arm has been strengthened, and when it stimulates the inner breath, the entire right arm seems to be enchanted by flames, emitting a faint fiery red light like a fire dragon.

Yu Feng could feel that after the entire arm was strengthened by the red fire, the local strength had at least doubled.

However, it consumed extremely internal breath, and in just a few seconds, it had already consumed at least half of Yu Feng's internal breath.

This......

It seems that this Red Fire Ghost Body can't support a long-lasting battle, and if it is occasionally used as a sneak attack to catch the opponent off guard, the effect may be good.

"It's worthy of Danhuo."

Yu Feng couldn't help but sigh.
