After taking the Ning Yuan Grass handed over by Elder Chen, Lin Bai still put it into the Dan Furnace as he had done the previous two times.

After a cup of tea.

Lin Bai put the refined medicinal liquid into the bottle, perhaps because practice makes perfect, this time the purity of the medicinal liquid reached eighty.

"How the hell did he do it?" Elder Chen was puzzled in his heart, he would not believe that the goddess of luck favored him to death.

But he couldn't explain how Lin Bai moved, obviously he was staring at Lin Bai the whole time, and Lin Bai's method of refining medicinal herbs was the same as others, but he injected true qi into the Dan furnace and used the Dan furnace to refine the spirit grass.

"Then refine this spirit grass. Elder Chen handed a Ning Yuan Grass to Lin Bai again.

After Lin Bai took over the Ning Yuan Grass, he still followed the steps and continued to refine it.

After Lin Bai began to refine, Elder Chen secretly ran a technique to spy on the changes in the true qi in the Dan furnace.

Another cup of tea, Lin Bai once again put the refined medicinal liquid into the bottle.

"What the hell is going on?" Elder Chen was getting more and more confused at the moment, he couldn't see what Lin Bai was doing at all, Lin Bai's refining method was obviously the same as others, and he was also injecting true qi into the Dan furnace like others, but the purity of the refined medicinal liquid was terrifying.

"Let's see if you can refine this spirit grass. "What Elder Chen handed Lin Bai this time was a turquoise grass flower, no longer Ning Yuan Grass.

The spirit grass Lin Bai handed over by Elder Chen recognized it at a glance, and it was recorded in the wordless pill book that this was a healing spirit grass with a single grade.

The reason why Lin Bai was able to refine a high-purity medicinal liquid without being discovered by Elder Chen was because when he was refining the spirit grass for the second time, he had an idea in his heart, that is, to integrate the Dan Decision into those True Qi Channels in the Dan Furnace.

After all, in the final analysis, Dan Dueling is just a way of using true qi, and those hand duels are just to express this "way".

So what if you change this expression to those pathways in the Dan furnace?

Those pathways are essentially just a manifestation of the method of fire refining, which means that you can also use those paths to perform Dan Duel.

Lin Bai said to do it, and the paths in the Dan furnace extended in all directions, so he ran the true qi in those paths in the same way that he ran the true qi when he was running the Dan decision.

The result was gratifying, his idea was correct, and he also refined a medicinal liquid with a purity of seventy percent as he wished, and it reached eighty percent just now.

Lin Bai asked himself that it was impossible for Elder Chen in front of him to see his own method, after all, what Lin Bai had changed was only the way of operation of True Qi, and those pathways would eventually be filled, and their appearance was no different from the method of fire refining.

"Refine?" After Elder Chen handed over the blue flower, Lin Bai had a question in his heart.

He is only at the tenth level of qi refining, although he is an extreme realm martial artist, but refining spirit grass also has realm requirements, like a grade spirit grass, at least a martial apprentice cultivation is required, after all, compared to martial apprentices, the quality and quantity of martial arts true qi in the qi refining period are too different from those of martial apprentices.

But after some hesitation, Lin Bai still planned to practice, he wanted to see what tricks Elder Chen in front of him wanted to play.

After refining it several times, Lin Bai skillfully put the spirit grass into the Dan Furnace and integrated the Dan Decision into the passage of the Dan Furnace.

After a cup of tea.

This time, the crystal clear blue flowers in the Dan furnace did not ooze medicinal liquid like the previous Ning Yuan grasses, which made Lin Bai feel a little hindered.

Lin Bai frowned:

"Sure enough, it's still too reluctant to refine a grade of spiritual grass with the cultivation of Qi refining period food..."

But he didn't want to give up, he wanted to try where his limit was, after all, the quality and quantity of his true qi were much higher than those of ordinary qi refining martial artists, and with Dandu, he didn't think he was without the possibility of success.

Drink!

Lin Bai shouted loudly in his heart, increasing the amount of true qi input, and at the same time integrating Dan Du into it.

With the injection of Lin Bai's true qi, the temperature in the Dan furnace was also rising, and the blue and blue flowers became more crystal clear.

Slowly, the green grass finally oozed a drop of medicinal liquid.

At this time, Elder Chen on the side was already so surprised that he couldn't close his mouth, he had been peeking at the situation in the Dan furnace, originally he asked Lin Bai to refine this spirit grass just to test Lin Bai.

He didn't think that Lin Bai would refine the medicinal liquid at all, but what he didn't expect was that the truth made him lose his teeth, Lin Bai not only refined the medicinal liquid, but also looked at the situation and was very likely to succeed.

What method did Lin Bai use?

And how could Lin Bai's true qi be so strong?

He had no way of knowing this, he couldn't see that Lin Bai had done anything at all, everything was the same as when an ordinary Alchemy Hall disciple was refining the medicinal liquid.

Elder Chen's eyes flashed, and he seemed to have changed his attention, and continued to spy on the situation inside the Dan Furnace.

After refining the first drop of the medicinal liquid, Lin Bai was overjoyed, and then he added strength.

Everything was developing in a good direction, and the green grass in the Dan furnace was oozing more and more medicinal liquid, and at this time, a layer of fine sweat appeared on Lin Bai's forehead.

The first-grade spirit grass was not as easy to refine as he imagined, and the difficulty was several times higher than that of the non-grade Ning Yuan grass, and the amount of mind consumed was much higher.

Tick!

Finally, the last drop of medicinal liquid fell on the bottom of the Dan furnace, Lin Bai wiped the sweat on his forehead and put the medicinal liquid into the bottle, the purity of this bottle of liquid medicine was only one percent, but Lin Bai was already very satisfied, after all, he was only a martial artist in the Qi refining period, and the blue flower was a first-grade spirit grass.

Lin Bai handed the medicinal liquid to Elder Chen and then spoke:

"Elder, the disciple's cultivation is low, and he can only refine to this extent. ”

After taking the medicinal liquid handed over by Lin Bai, Elder Chen was already speechless in shock, he didn't expect Lin Bai to really refine it, although the purity was only one percent.

But you must know that he only has the ninth layer of qi refining! And this blue flower is a first-grade spirit grass!

After a long time, Elder Chen spoke:

"What cultivation do you need to refine the second-grade spirit grass?"

After hearing Elder Chen's words, Lin Bai felt a little inexplicable, and he didn't understand the other party's words very well, but after estimating his ability, he still said stubbornly:

"About the sixth floor of martial arts. ”

Martial Disciple Sixth Floor?!

Elder Chen seemed to be startled by Lin Bai's words, and exclaimed in his heart.

He knew at this time whether Lin Bai was lying to himself, but after looking at the liquid medicine in his hand, he felt that Lin Bai seemed to be able to really do it.

Then Elder Chen asked:

"What purity can be achieved?"

Lin Bai hesitated for a moment and then said:

"About fifty percent. ”

Fifty percent is just a conservative estimate, he has only mastered the most basic refining pill decision on the wordless pill book, and the purity of refining spirit grass is already so high, you must know that there are more than a dozen refining pill decisionless pill books that are more advanced than the liquid extraction decision.

After Lin Bai finished speaking, Elder Chen took out a bag from his sleeve and threw it to Lin Baidao:

"Wait for your martial disciple on the sixth floor, come and do me a favor, now you can go. ”

Lin Bai took the bag, and the weight of the bag was not small:

The disciple took his leave. ”
