Wen Mochen walked in front with his hands, Xu Huaishan and a few disciples who were in charge of the competition followed step by step with a group of people who participated in the competition, and soon came to the side hall on the right side of the main hall. (Please search Bayi Chinese Net, the fastest updated novel website!)

It is said to be a side hall, but the area is not small at all, and around the spacious hall, there are many small rooms side by side, which is where these participating disciples will refine their own pills later.

Wen Mochen stopped, looked back at the group of disciples, and said with a flat expression: "The content of this big competition is to refine the second-level spirit Yun Pill, each person will get three sets of elixir materials, the time limit is three hours, after getting the elixir, choose the room by yourself, and start the timer immediately!"

Everyone was stunned when they heard this, they couldn't imagine that Wen Mochen was so straightforward, and he directly announced the start without even saying half a word of nonsense, and after reacting, everyone hurriedly rushed to Xu Huaishan and a few other responsible disciples to collect the materials, and then each chose a room, went in and started alchemy.

And hearing that the content of the competition was to refine the second-level Lingyun Pill, Lin Feng was also a little surprised, the material of the Lingyun Pill was very precious, and it was actually used casually for these disciples to test the alchemy pill, Ling Yuemen was really willing, but the Lingyun Pill was indeed the most powerful elixir that could test the alchemy technique, and he was worried that it would be bad if the competition was an elixir that he could not refine, but now he was relieved, he knew the refining method of the second-level Lingyun Pill, and he had practiced it many times.

After everyone else basically received the materials into the room, Lin Feng also received his own materials, and then chose an inconspicuous side room and walked in.

After closing the door, Lin Feng looked at the room, it was about five meters square, the layout was extremely simple, but the sound insulation effect seemed to be good, after closing the door, it felt as if it was isolated from the outside.

Moreover, after entering the room, Lin Feng noticed that the temperature around him had risen a lot, and the fire aura in this room seemed to be much richer than the outside, and after careful observation, he was surprised to realize that the surrounding walls seemed to have joined the fire ore building, so it made the fire aura in it more active, that is, if you alchemy in it, it would be easier.

There is even a shallow trough in the center of the room dedicated to the Dan furnace, and the bottom of the shallow trough is a fiery red stone slab, which is obviously also a fire ore, and it is even more advanced than the surrounding one, and if the Dan furnace is placed on it, it can better condense the fire.

In short, the qiē in this room is designed for alchemy, and in this alchemy, you get twice the result with half the effort.

After Lin Feng finished looking at the room, he walked to a futon on the inside and sat down, and took out the Dan furnace, and then checked the elixir bag he received.

Indeed, as Wen Mochen said, the elixir bag contains three groups of materials for refining the second-level Lingyun Pill, and the three-hour time limit can basically only refine the three-furnace Lingyun Pill, so even if someone has more materials by themselves, it is basically useless. Of course, if you are absessed at the beginning and scrap all three sets of elixirs in a short period of time, then if you still have the materials, you can continue to alchemize, which is not a violation.

"Whew...... So, let's get started!!"

Lin Feng adjusted his state, and then raised his right hand to urge the true yuan, and a puff of spiritual fire condensed out and entered the Dan furnace, and when the refining fire ignited, he threw the first group of elixirs into it.

As for why the spiritual fire was used instead of lava fire, needless to say, of course, it was because I didn't dare to use it, after all, there was an elder outside, and once I took out the strange fire, it would definitely be revealed, which would only summon trouble, so I could only use the spiritual fire.

Using spiritual fire to refine the pill is naturally more difficult than using a different fire, but Lin Feng has also been practicing for the past ten days, but there is no problem, under his full control, the elixir in the pill furnace is being refined little by little.

Time passed little by little, and after more than forty minutes, Lin Feng's True Yuan had already consumed more than half, and he took out a top-grade Huiyuan Pill and threw it into his mouth to replenish the consumed True Yuan.

After another moment, just when this furnace of pills was about to end, the refining fire in the Dan furnace suddenly jumped unsteadily, and before Lin Feng could remedy it, he heard a muffled sound of 'bang', and the entire Dan furnace shook slightly, and then a smell of burnt paste wafted out.

Lin Feng frowned, his eyes showed a trace of disappointment, and he sighed in his heart, he was still not good after all, although he had been practicing alchemy with sufficient elixir in the past six months, but after all, the time was too short, and there was still no way to guarantee success in refining the second-level Lingyun Pill, which was the most difficult of the second-level pills.

However, he was not discouraged, and there was no big problem with wasting this group of elixirs and an hour, because in his plan, as long as he could refine a furnace, he should also have a chance to win.

After cleaning up the medicinal residue in the Dan furnace, Lin Feng took out another Hui Yuan Dan and took it, and then began to refine the second furnace of Dan medicine.

After another hour or so, Lin Feng, who had always looked solemn, suddenly flashed a flash of joy in his eyes, raised his right hand and put it on the Dan furnace, and then closed his eyes, as if he was really engrossed in controlling the fire refining.

The refining fire in the Dan furnace was obviously more vigorous, and after a while, a faint medicinal fragrance came out of the Dan furnace, but it seemed to be mixed with a slight smell of burning, which showed that although the pill in the furnace was refined, the quality was not very good, I am afraid that at most it was only a medium grade, maybe some of it was only a lower grade.

Under normal circumstances, at this time, it should be Qi Ding Dan, but Lin Feng did not do it immediately, but still felt something with all his attention, the true yuan in his body fluctuated rapidly, and he said silently in his heart: "Repair!"

"Bang!!"

In an instant, the flame in the Dan furnace rose again, as if a special force was filling it, but in a moment, a refreshing Dan incense floated out of the furnace, several times stronger than before.

Lin Feng opened his eyes, a smile appeared on the corner of his mouth, and with a wave of his right hand, he opened the top lid of the Dan furnace, and a stream of true yuan wrapped in the pill flew out.

The seven pills fell into Lin Feng's hands, he took a closer look, nodded with satisfaction, and said to himself: "Three perfect quality, four 1o% broken top grade, should be about the same......"

Originally, it was only a medium-grade or even low-grade quality pill, but it suddenly became a top-grade pill, and the reason for this, needless to say, was naturally a repair technique, and the difference from before was that this time Lin Feng repaired these pills through the Dan furnace.

This is the 'new use' of a repair technique that came out of the real yàn that night after Lin Feng decided to participate in this big competition ten days ago, before that, he always held the equipment he wanted to repair in his hand, and then repaired it, and after the real yàn, he didn't have to 'hold' it now, as long as he wrapped the target with refining fire, then he could use the repair technique.

When refining this furnace of elixir, Lin Feng did not use all the elixirs he had put in for alchemy, but set aside a small part of it for 'backup' next to it, and when the elixir was refined, this spare part of the material was used to repair the newly refined elixir, which is why under normal circumstances, a group of materials that should be refined ten pills was only refined, and only seven were refined.

The reason why Lin Feng took great pains to develop such a method of repairing the pill in the Dan furnace was that he was worried that if he took out the pill and then repaired it in his hand, it would be revealed, after all, although there were no outsiders in this room now, if someone used his divine sense to investigate, he could show his behavior, so that it was repaired in the furnace before the pill was baked, and I believe that even if someone used his divine sense to probe the situation in his room, it would not be detailed enough to even explore the inside of the Dan furnace.

In fact, Lin Feng was a little worried, there were nearly forty people participating in the big competition this time, it was impossible for Wen Mochen outside to observe everyone's situation, he only paid attention to a few of the most outstanding disciples at most, and he didn't even have any interest in paying attention to strange disciples like Lin Feng.

However, the repair technique is Lin Feng's own biggest secret, and it must not be exposed, so it is always right to be cautious, even if it is a redundant move this time, but the new use of this repair technique that he has come up with for this reason will also have a great effect in the future.

......

Then Lin Feng put away the seven pills in his hand and began refining the third furnace of Lingyun Pill.

After another period of time, the third furnace of pills was also refined, but the situation was not as good as the second furnace, most of them were just lower grades when refined, and there were even two waste pills, but this naturally did not make it difficult for Lin Feng, after some repairs, when the pills were baked, they were already of top quality. The reason why it is 'just' of the highest grade is because the materials for repair are insufficient, so it has not been repaired to perfect quality, just like the second furnace is only enough for three pills to be repaired to perfect quality.

This was actually in Lin Feng's plan, he wouldn't be stupid enough to make all the pills of perfect quality, that would be too exaggerated, but it would be easy to attract the suspicion of others.

After checking the seven top-grade Spirit Yun Pills in his hand, Lin Feng turned his head and looked at the timer next to him, the time was just right, and the three-hour time limit was about to expire.

Putting away the Dan furnace, Lin Feng took another Hui Yuan Dan, and after breathing for a few minutes, he stepped on the end time and walked out......
