Slowly opening his half-closed eyes, the corners of Han Chen's mouth also turned up slightly, and then he was in a good state, and the aura in his body was also running unconsciously.

With a wave of his palm, the Dan furnace that was originally parked in front of him also levitated, and the spiritual grass on the stone platform also followed closely and threw itself into it.

Han Chen's left hand urged the flames again, and wisps of fire continued to move towards the spirit grass in the Dan furnace under Han Chen's control.

Refining back and forth, drop by drop of essence also slowly increased with the passage of time, until all the spirit grass that Han Chen needed had been refined, and there was no accident at all, and Han Chen was still very satisfied with this.

And while Han Chen was working hard to refine, the others were not lagging behind, and they were all working hard to refine the elixir for themselves.

The refined essence was suspended in the Dan furnace, and seeing this, the movements in Han Chen's hand naturally did not stop, and he continued to refine it to slowly form a spirit pill.

Slowly, a faint danxiang also wafted out, and asked about this smell, although Han Chen had smelled this smell countless times before, but at this time, Han Chen was also full of joy when he asked about this smell, after all, this was refined by him himself, and the sense of accomplishment was also full.

After the faint danxiang, there is a thick danxiang, after this step, it is not far from success, with the many experiences of previous failures, Han Chen naturally will not take this lightly, concentrate on it, and will not miss any detail.

Subsequently, after the rich danxiang, the return to the basics disappeared, Han Chen didn't pay much attention to this, but he was more cautious, and nothing happened during the period, since Han Chen, everything was very smooth.

With unusual caution, soon, a spirit pill in the Dan furnace that had begun to solidify floated in the Dan furnace, and under the Dan furnace, Han Chen's aura flame never stopped according to the Dan Fang.

As the flames under the Dan furnace disappeared, all of Han Chen's movements at this time also stopped, and the elixir that had been faint and illusory in the Dan furnace was also really floating in the Dan furnace at this time, looking at the Dan furnace, Han Chen's stopped palm slammed towards the Dan furnace, and the lid of the Dan furnace was lifted as a result.

Quickly took out the elixir from it, looking at the elixir in his hand, the smile on Han Chen's face also quickly emerged, looking at his results, even if he had already succeeded, Han Chen still couldn't stop being happy in his heart.

In addition to being happy, Han Chen also put it away, no longer wasting any more time on it, and now he only had this last product left, as long as these three grades of Tianyuan Righteous Qi Pill were successfully refined, this level would be considered to be passed.

And just when Han Chen's alchemy was refined, more than half of the time had passed, and on the field, some people were happy and some were sad at this time, everyone was different.

Han Chen only paid a little attention to this, so he didn't pay much attention to it, and the rest of the time, he mainly refined these three grades of Tianyuan Righteous Qi Pill.

Different from the previous two times, in this Dan Fang, the method of refining the Sanpin Tianyuan Zhengqi Pill was not as detailed as the previous two times, before, Han Chen used this Dan Fang for a large part, every step, Han Chen would prepare before refining, and he had carefully studied it, which caused his speed to be considered faster than everyone else.

But at this time, the method of refining the three-grade Tianyuan Zhengqi Pill was not a little worse than the previous two times, and the key details of each of the previous places were gone, although the previous two times were much the same, but Han Chen did not dare to guarantee that the method of refining the third-grade was still the same.

Therefore, every detail that was not available had become the biggest problem that Han Chen had to solve before, if this could not be solved, he would never be able to refine these three grades of Tianyuan Righteous Qi Pill.

Touching his chin, Han Chen stopped and thought for a while, and soon, Han Chen knew that there was a feasible way, and this method depended on his previous preparations.

Looking at the various spirit grass materials on the stone platform in front of him, Han Chen smiled and immediately began to move.

Han Chen put away the spirit grass materials that were not needed on the stone platform one by one, as the saying goes, mosquito meat is also meat, no matter how small this wealth is, Han Chen will accept it all.

After Han Chen put away all the useless leaves, he divided the remaining useful leaves one by one, and he didn't dare to be sloppy in every place, what spirit grass materials should be in that place, how to place them, and where to put them, Han Chen remembered them clearly.

Han Chen's remaining materials can be said to be very much, enough for Han Chen to refine, when they are divided, looking at these spirit grass materials, he didn't expect that he would have so many left after pouring this last step, but this is also due to the many spirit grasses he took out from his spirit grass library before, and now on this stone platform, it can be said that more than sixty percent of them are all his previous spirit grasses, and the rest are all prepared by Mu Lao.

And now the spirit grass on this stone platform, Han Chen also knows all of them, and the name is also called, no longer like at the beginning, and this is all due to Ye Sheng, since he wanted Ye Sheng to ask for advice, his understanding of these spirit grasses can be regarded as having some foundation, that is, among the spirit grass that is still left on his body now, Han Chen also knows most of it, and all these various credits are Ye Sheng's.

Looking at these spirit grasses, Han Chen exhaled slightly, and also sighed very much at these changes in himself, if it was a few months ago, Han Chen didn't understand anything, but in this short period of time, Han Chen's changes were leaps and bounds, when he thought of this, Han Chen couldn't help but sigh how correct the decision to come out and see the world was at that time.

With all the preparations ready, Han Chen was about to start his plan.

There are still so many spirit grass materials left, Han Chen will naturally make full use of them, after understanding these spirit grasses, Han Chen also knows which ones are precious and which ones are not, and a few of them are precious, Han Chen will naturally pay attention to them, as for which ones are common and not precious, Han Chen wants to use them all to ensure that he can successfully refine this last three Heavenly Yuan Righteous Qi Pill.

And this refining method is still changing the soup and not changing the medicine, this time, he didn't have the detailed hints on the Danfang, only some rough hints, Han Chen had already thought of the solution, which was to use these many spirit grasses, continue to refine, improve, and finally successfully refine it.

As soon as he thought of this, the movements in Han Chen's hands had already been performed, and with skillful operation, Han Chen quickly began to refine, but without the previous prompt, not long after the beginning, Han Chen made a mistake and failed.

In terms of controlling the flames, Han Chen failed here, at the beginning, Han Chen was quite successful in refining, but then, not long after a while, the power that was just right seemed to be suddenly magnified, and directly burned the spirit grass material to ashes.

For this failure, Han Chen was also a little inexplicable, and took another plant, this time, Han Chen proceeded more carefully, refining very slowly at first, carefully recalling the failure just now, but he really couldn't think of why he failed just now.

"Since that's the case, then I'll take my time and see why this is failing, this shouldn't be!" Han Chen muttered, and what Han Chen didn't know was that because at this time he was already using a third-grade spirit grass material, compared to the previous spirit grass material, the current material is more difficult and laborious to refine, and there are two changes in the refining of a spirit grass, which is also the reason why Han Chen failed, of course, he is not clear now.

Facing the spirit grass material in front of him that was exactly the same as before, Han Chen was cautious, not daring to relax in the slightest, as he slowly refined it, a drop of spirit grass essence was also refined early, and at the same time that this essence was refined, the luster of the spirit grass from the lower end of the part disappeared by as much as a quarter.

Feeling the changes in the spirit grass, Han Chen roughly calculated how many drops of the spirit grass essence he wanted to refine, and soon, the two drops were successfully refined, and the luster disappeared a lot again as Han Chen thought, and the luster disappeared from the bottom up.

Han Chen naturally sensed this change and kept it in mind.

Just as he was about to refine the third drop, the same change as just now appeared, and the originally stable fiery silk instantly swept through the spirit grass, burning it to ashes.

And here, Han Chen carefully observed every place, and Han Chen also understood the general problem, in Han Chen's opinion, this is the difficulty of refining the three products, which will consume a lot of time, so go on like this.

Immediately, Han Chen looked at everyone and thought in his heart, "It should be, other people are like this!"

And Han Chen's guess is not wrong, now many people are facing this difficulty, and at this point, they have an understanding of this spirit grass and a subtle understanding of refining.

Unlike before, the rest is a matter of time, as long as everyone can figure out the original of this, it will not be a problem to successfully refine it.

And Han Chen, who knew what the problem was, naturally refined it again after recovering for a while, and he didn't want to waste time.

As soon as he thought of this, Han Chen's next step was another skillful operation, and the identical spirit grass also slowly appeared under his refinement, and two drops of spirit grass essence slowly appeared.

At this point, just as Han Chen was refining the third drop, Han Chen decisively quickly straightened the power of his flame to the lowest level, and sure enough, after Han Chen reduced his effect, there was no change like before.

Sensing this change, the worry in Han Chen's heart also disappeared, and then, under Han Chen's continuous refinement, the third and fourth drops also appeared.

And after refining these four drops of essence, the spirit grass lost its luster and lost its spirituality.

Without hesitation, Han Chen immediately put in the next spirit grass, with the previous experience, Han Chen got started quickly, and slowly increased the power of his fire wire, but as soon as he increased it a little bit, the spirit grass instantly ignited again, and everything before was completely wiped out.
