After cleaning up the Dan furnace, then Han Chen didn't rush to continue, although he already understood where his mistake was, but if he wanted to succeed, Fei didn't have a little bit of effort.

Looking at it like just now, it will not be easy to control the fire and refine, let alone the later, it can't be broken during this period, if it wasn't in the best state, with Han Chen's overall situation now, it would undoubtedly not work.

The time of cultivation did not take long, during this period, Han Chen was not idle, not only looked around, wanted to see how others were refining, which was good for him, through the small refining just now, Han Chen's view of alchemy rose to a great level, and he originally looked at the middle-aged man who succeeded three times, so he was a little contemptuous of this alchemy, thinking that he only needed a few more times to succeed.

Thinking back to before, Han Chen felt how stupid his previous idea was!, "I underestimated this alchemy too much, even if the grade of the elixir to be refined is very low, but for someone like me who doesn't understand anything, this is still very difficult." ”

Looking around, Han Chen found that many people had already started refining, but there were still some people who were still indifferent, and Han Chen didn't know why they didn't do it for a long time, you know, their time was not infinite, but only seven days, in Han Chen's perception, this time had already passed for a day, he couldn't think of a reason, why these people were so leisurely, "Are they all alchemists?"

Looking at the refining techniques of these people, Han Chen found that they were all similar to the middle-aged man's before, only different in some aspects, but they were also similar, although these people were also refining, but so far, except for the middle-aged man, none of the others had succeeded in refining, it was obvious that the level of these people was still a little worse than that of the middle-aged man, although the middle-aged man was also a half-ass.

And the middle-aged man naturally noticed all this, and the corners of his mouth couldn't help but curl up slightly, as if to say, it's not as good as me, or I'm good, this time I will definitely be the first to finish refining.

Having said that, he also has that capital, at this time he is indeed ahead of everyone, and now he has already started refining the second-grade elixir very early, although he has been constantly failing since the beginning, but after each failure, he will improve a little, according to this, he estimates that within two days today and tomorrow, he will be sure to refine the second-grade elixir.

And in the remaining few days, he also believed that with the success of the first two times, it would be of great help to his subsequent refining, and the probability of successfully refining the fourth grade was also very great.

Therefore, when I feel distressed by seeing that others have not finished any of them, a sense of superiority arises in my heart.

And after looking at this, Han Chen not only found that no one had successfully refined so far except for the middle-aged man, but also found that among the remaining refining people who had not done it, most of them were people from the sect, including Ruoxi Ye Sheng and Xuanyuan Yu, who he was familiar with.

Now they haven't made a move yet, he doesn't understand why this is happening, "It's not a long time!" Just when Han Chen was puzzled by this, those people moved, whether it was Ye Sheng or Xuanyuan Yu, and the black-robed person who was the first to come in at the beginning, they all moved, not at the same time, but they started one after another in front of Han Chen's eyes.

"Why are you still acting together?" Seeing this scene, Han Chen muttered.

But the fact is that the reason why Ye Sheng and the others have only started to slowly start refining until now is also for a reason, among those of them who have only started now, most of them are disciples of the sect.

And although they don't know how to refine the elixir, they are not alchemists, but in their sect, there is no shortage of alchemists, in this aspect of refining the elixir, although they have not touched it, but they have more or less heard those alchemy masters in their sect explain this aspect, and the Tao is only starting now, because in addition to thinking about the Dan Fang before, they are recalling some of the key points that the alchemy master talked about at the beginning.

In their opinion, even if it took a little more time, as long as it helped them in refining the elixir in the future, it would be worth it.

And after such a long time, they also have some understanding of alchemy, not to mention that among them, the alchemists in their sect have personally practiced how to refine pills for them and explained to them, and when they see these at this time, it is not as strange as they faced these at the beginning.

Looking at the people who had already started refining, Han Chen glanced around again, and then stopped paying attention, now everyone has already started refining, the Dan furnace hangs in front of everyone, and the spirit grass materials are put into the Dan furnace with everyone's control, and slowly refined.

And Han Chen's side, who had recovered almost completely, was ready again and began to refine, with the first experience, this time, Han Chen controlled the power of the fire silk to a very low level, and with the input of the spirit grass material, Han Chen controlled the fire wire to slowly penetrate into the spirit grass material and began to refine it.

And this time Han Chen did not have the same situation as the first time, this time he successfully controlled and refined the fire wire, and there was no burning.

Seeing this scene, a smile immediately appeared on Han Chen's face, and seeing that the fire silk began to be slowly refined, Han Chen knew that what he was doing was right, and he couldn't help but be full of confidence in it.

After a while, finally, under Han Chen's continuous use of fire wire traction and refining, a drop of essence full of spirit grass material was finally refined by Han Chen, looking at that drop of spirit grass essence, Han Chen's mood was suddenly overjoyed.

But after a while, the joy in Han Chen's heart disappeared completely, replaced by a boredom in his heart, his brows furrowed slightly, refining this drop of essence just now, Han Chen took a lot of time, but at this moment in the Dan furnace, the smoothness of the spirit grass material has only gone a little, which can't help but make Han Chen worried, if it goes on like this, I'm afraid this time is not enough, this efficiency is too slow, just like this, he is afraid that by the last day, he will not be able to successfully refine one.

"No, it can't go on like this. Han Chen said secretly, he also knew that his method was right, but it was still a little worse, and that point of difference depended on the efficiency of his refining, as long as this problem was solved, this refining aspect would definitely be nine out of ten.

Looking at the slightly dimmed spirit grass material in the Dan furnace, Han Chen fell into deep thought, but soon, Han Chen looked directly at it.

"It looks like we can only give it a try!" Han Chen muttered.

In the contemplation just now, Han Chen thought and thought, but he still had no clue, but he thought that it was because the power of the flame was too great that he controlled its power to a very low level, which led to the successful refining.

But the efficiency is not high, thinking about it this way, Han Chen came up with the idea that if the power of this flame is fine-tuned in the control and fine-tuning, will it be able to speed up his refining speed, after all, the power is great, and the refining will also be opened, but he is not sure, if the power of the flame is increased, it will lead to the same as the first time, causing the spirit grass material to ignite, you know, this spirit grass is all containing aura and vitality, when encountering this aura fire, if the power and temperature are too high, it will produce a co-combustion effect, and the success will fall short.

But now Han Chen can't think of any other way, he can't help it, if he goes on according to that method, he will definitely not be able to pass this second level, there is no way, so he has to take a risky move.

Looking at the spirit grass material in the Dan furnace, the temperature and power of the flame in Han Chen's left hand had risen slightly under Han Chen's control, and then Han Chen was controlling the fire silk from it to refine the spirit grass.

Immediately after that, the fire silk came into contact with the spirit grass material, and the burning did not follow, seeing this scene, Han Chen suddenly felt a lot better, it seems that this method will work, but what he doesn't know is where this limit is, if the power increase is exceeded, it will definitely cause his spirit grass material to burn.

As the fire silk continued to refine under Han Chen's traction, soon, another drop of spirit grass essence was refined by Han Chen, and this time the time it took was far lower than the last time, but it made Han Chen still a little disappointed, although it was faster, but it was still not enough, according to this, he still couldn't finish it.

"What should I do now, is it possible that I still have to raise this power and temperature?" Han Chen scratched his head and muttered to himself a little overwhelmed.

After saying that, Han Chen once again increased the power of the flame in his left hand, and once again pulled the fire wire towards the spirit grass in the Dan furnace, and the spirit grass in the Dan furnace, after the previous refining, was much dimmer again, and some places on the branches were also yellowed, and this was obviously the result of being refined.

And the fire silk that Han Chen pulled was also convenient for the spirit grass to come into contact with, as soon as it came into contact, before Han Chen could react, a scorching smell came to his face, and then, the flames quickly swept through the spirit grass with the two drops of essence.

Smelling this smell, by the time Han Chen reacted, it was already too late, and the ingredients inside and the two drops of essence had been burned away.

Seeing this scene, Han Chen's face darkened suddenly, and his previous efforts were in vain.

While being annoyed by this, Han Chen was very helpless, this time he failed again, but this time Han Chen also probably mastered the power of the flame needed for this refinement, and he needed to control it well in order to refine it intact, as for the efficiency, Han Chen couldn't think of what to do for the time being.

Looking at the Dan furnace, Han Chen exhaled.
