While watching the black-robed man refining, although this may increase the time consumed for Han Chen, for him, the gain is not small, and while watching carefully, he also found that the other party's flame power and temperature are similar to his, but the difference is above each other's efficiency.

This made Han Chen frown a little, but Han Chen was not sure, and then Han Chen did not dare to delay, and hurriedly turned to look at the stone platform in front of him, and after thinking about the Dan Fang for a while, Han Chen began to refine it.

With a wave of his palm, the Dan Furnace was also suspended in front of him, now he was not like before, he used brute force to shake this Dan Furnace, after knowing the method, Han Chen was also extremely fast.

With the Dan furnace levitating, Han Chen waved his right hand, and a spirit grass was directly thrown into the Dan furnace, at this moment, the spirit grass on the stone platform in front of him could be said to be countless, densely packed with all of them, so Han Chen was not too anxious, in his opinion, when it really didn't work, he would try his best to refine, and his perception would naturally become more and more, and in the end, it would naturally be refined.

Without thinking much about it, the flame in Han Chen's left hand immediately rose, and a wisp of fire immediately swam out, heading towards the spirit grass material in the Dan furnace, Han Chen concocted it in the same way, and began to refine it according to the previous method.

But the result is the same as before, the efficiency of refining is extremely slow, and if it continues like this, it is impossible for him to complete the refinement.

"That's really the case!" Han Chen thought to himself, then stopped the refining in his hand, and then instantly increased the firepower, incinerating the spirit grass materials in the Dan furnace completely.

Immediately, Han Chen clapped his hands and muttered, "Sure enough, there is not much consumption in this mind." At this time, he already roughly knew in his heart the reason why his efficiency was so low, in the refining just now, although Han Chen was able to successfully refine, but he also found that his consumption in the mind was very small, on the other hand, as long as it was successfully refined, all of them consumed a huge amount of energy, which made Han Chen perceive, and why he consumed so little, this was his problem.

Thinking of this, Han Chen's heart immediately turned around, the fire wire he controlled needed the mental aspect, and he consumed less, proving that the fire wire he controlled was not enough.

As soon as he thought of this, Han Chen immediately began to experiment, although this idea was already his efficiency problem in his opinion, but whether it was or not, he had to try it himself.

After adjusting his state, Han Chen immediately set out to verify the thoughts in his heart, and with another wave of his right hand, a spiritual grass material was immediately thrown into it, and the spiritual energy flame that had disappeared in his left hand also followed closely behind, and immediately appeared.

As soon as his mind moved, a wisp of fire immediately swam out of the flames and headed towards the spirit grass in the Dan furnace, and then Han Chen's mind was controlling the first wisp of fire at the same time, and it was a wisp of fire that burst out of the flame in Han Chen's left hand, seeing this scene, Han Chen was immediately overjoyed, it seemed that his idea was right.

And after the second thread of fire appeared, Han Chen still didn't feel any fatigue, and then, his mind moved again, and another thread of fire sprang out, followed by another wisp...... As the filaments of fire continued to increase, each wisp was like the first wisp, and Han Chen gradually felt weak, and finally by the twelfth wisp, Han Chen's face was already slightly pale, this was already the limit of what he could distract and control, and no more than half a wisp would work.

"This little guy, has you finally found out? It's really embarrassing for him, twelve wisps, it's not bad!" Mu Lao saw this scene, nodded well, at this time he was still watching everyone in the dark, Han Chen gave him a good impression at the beginning, at this time he naturally paid special attention to Han Chen, when he saw Han Chen struggling about efficiency, he wanted to see how Han Chen would solve this problem.

Sure enough, Han Chen did not live up to his expectations, and quickly solved the problem, he also knew that Han Chen was also a novice who had just started refining, but the more so, the more he could see Han Chen's alchemy talent, and Han Chen did not disappoint him, although the talent he showed was not a blockbuster, but it was very rare for Han Chen to be able to do such a thing at his age.

After knowing that twelve wisps was his limit, Han Chen hurriedly eliminated one wisp to reduce his pressure, and after reducing one wisp, Han Chen's mental pressure was suddenly reduced a lot, in his opinion, twelve wisps might be faster, but in that case, he wouldn't be able to last long, because refining also needed the help of his mind.

At the same time, he controlled the eleven wisps of fire filaments and refining, but he still resisted a little, and then, after he reduced one wisp again, he controlled the remaining ten strands of fire filaments and went towards the spirit grass material in the Dan furnace.

With wisps of fire threads constantly passing back and forth through the spirit grass material, soon, drop after drop of spirit grass material essence was continuously refined, and the efficiency can be described as a thousand miles a day, compared with the original, more than ten times faster.

In a few dozen breaths, Han Chen had finished refining all of them, and he didn't feel any discomfort, and then Han Chen's right hand waved again, and then several more materials were thrown into the Dan furnace.

Han Chen didn't dare to be careless about this, every step was according to what was said on the Dan furnace, step by step, and then Han Chen controlled the fire silk to continuously refine these spirit grasses back and forth.

Time passed slowly, and in the blink of an eye, four or five teas had passed since Han Chen began to manipulate the ten wisps of fire and began to refine, and now Han Chen had already refined more than half of the materials needed on the Danfang.

But at this time, Han Chen had the biggest problem in front of him, now he was already feeling a little weak, but he didn't want to stop, otherwise, half of the efforts to refine would be in vain.

Thinking of the result, Han Chen couldn't help but strengthen his mind in his heart, he had to refine this elixir, and the speed of the original control of the fire silk refining had also slowed down a little, but in this regard, Han Chen still insisted, although the efficiency slowed down a little, it was still very fast.

After a few more teas, Han Chen's face was already pale at this time, and he was now only about a dozen spirit grasses.

But as the fire wire pulled by Han Chen passed through again and again, finally, when there was the fifth of the dozen or so plants left, the fire wire controlled by Han Chen broke all of a sudden, and it was obvious that Han Chen couldn't support it anymore, and in the end he still couldn't hold on.

The weakness brought to him mentally made him regret it in the end, this time the refining finally failed, but Han Chen undoubtedly gained a lot, but the only thing that made Han Chen feel distressed was that he wasted a lot of materials and time, you must know that in the end he would not be able to withstand it, Han Chen couldn't help but think, "If I knew earlier, I should have stopped first!"

And Mu Lao naturally saw this scene, and said lightly with some regret, "Didn't you resist it in the end, but also, after controlling ten wisps, with his early strength of Yuan Ling, it is already good." In fact, Mu Lao was also a little surprised when he saw that Han Chen actually used ten wisps to refine, and at that moment he guessed that Han Chen might fail.

In this way, if ten wisps are used to refine, although the efficiency will be greatly improved, but the amount of mind consumed is also a lot, you know, at the same time, can it not be difficult to distract and control ten wisps of fire wires! In Mu Lao's opinion, if Han Chen can reduce the controlled fire wires, the chance of succeeding in the end is very great, but with ten wisps, the result is also the same as he guessed.

And Han Chen, who failed at this time, did not pay attention to other people anymore, but was busy recovering himself, he had consumed a lot of time originally, and now he would work harder, and whether he could pass it at that time was a question he had to think about.

After a while, Han Chen's face was no longer pale, and he had obviously recovered almost, but the feeling of weakness in his mind was still fresh in Han Chen's memory.

He who has recovered almost completely, naturally he will not waste much time, and has already begun to prepare for a new round of refining, and this time Han Chen is seventy percent sure that he will succeed in refining, with the lesson of the last time, this time Han Chen will not dare to hold on to it again, and reduce the number of fire wires under his control to seven wisps, in this way, the pressure on him will also be greatly reduced, and he will not have the same situation as before, although in the end he failed to survive, but he didn't want to feel that feeling once.

It was another skillful operation, and soon, Han Chen had already entered the state.

With wisps of fire threads going back and forth through the refinement, although the efficiency was much less than before, it still didn't take long for Han Chen to refine a lot of materials, and at this time, there was still a lot of spiritual grass left on the stone platform in front of him, but it was still a lot more than at the beginning.

At the same time, on the other side, Ye Sheng and Ruoxi at this time had also successfully refined their first spirit pill, and both of them were very excited, and all this was due to the fact that they were fortunate enough to listen to a fifth-grade alchemist in their sect explain the knowledge of alchemy.

In the past, they didn't think that they would refine the elixir, so they didn't pay attention to it, but this time, their test was actually refining the elixir, and the two of them made full use of the knowledge of alchemy they heard at the beginning, and sure enough, both of them quickly refined it, although they also failed a few times.

At this time, the vast majority of people on the field have successfully refined, nearly two days, although most of them have never been exposed to alchemy before, but now there are detailed pills and almost enough materials, if they can't even refine a first-grade elixir, they don't have to continue, quit as soon as possible.

And the rest of the unrefined, most of them are loose cultivators, compared to the disciples of the sect, they don't have an alchemist to explain the knowledge of alchemy to them, so they haven't refined it for a long time, and most of these people are still a little worse.

At the same time, on Han Chen's side, at this time, the Dan furnace in front of him had already begun to slowly emit bursts of Dan incense, and it was obvious that he had finished refining.
