After practicing the ruthless way, the little sister is too strong

After returning to the courtyard, Xia Ling buried his head in studying. It took him nearly three days to finish reading the books given by Duan Nanxiao.

After reading them one by one, I understood a lot about the art of refining equipment, but when I tried to do it myself, I found that it was still difficult to remove the impurities in the Xuantian Crystal, let alone transform it into pure power.

However, there is one thing to be thankful for, that is, after tempering the Xuantian Crystal many times, her control over the divine fire has become much smoother.

Seeing her struggling for a long time, Xiao Jin said: "Go ask Duan Nanxiao about his techniques. Now that you have finished reading those books, he will not break his promise and not teach you."

"I was just about to go." Xia Ling used the wind element to put away the pile of books surrounding him one by one, then left the room.

As soon as I arrived at the gate of Duan Nanxiao's courtyard, I found that it was much tidier than before.

Of course, those houses that had become ruins had not yet been repaired, but overall they were a little bit better than that day.

"Stay there for a while, come in."

Duan Nanxiao's voice came from the courtyard. Xia Ling responded and walked inside.

He was sitting on a stone bench under the peach tree in the corner of the courtyard, holding a feather pen in his hand, writing something.

Seeing Xia Ling coming, Duan Nanxiao stopped what he was doing, raised his eyes to look at her, and said in a cold voice: "What do you want from me?"

Xia Ling took out the bundle of books from the space and placed them on the table. "I have finished reading the books you gave me a few days ago, and I have a written understanding of refining. This time I came here to ask you for advice on the refining method."

"You really have a good memory." Duan Nanxiao had heard other people mention her good memory, but he himself also had a photographic memory, so he didn't think it was special.

After saying this, he conjured up a magical herb from nowhere and said, "Try to use the divine fire to refine its power into a drop of concentrated liquid."

One drop?

Xia Ling didn't know what he meant, so she took it and did as he said.

It is more difficult to temper spiritual herbs with divine fire than with one's own spiritual fire. After all, the temperature is extremely difficult to control, and it will be burned to ashes if you are not careful.

Especially when it is still a seedling.

Sure enough, under Xia Ling's careful control, the spiritual herb in its seedling state did not turn into ashes.

However, the refined green liquid still contained a trace of dark impurities, which meant that the impurities had not been completely removed.

Is this... similar to the situation when refining Xuantian Crystal?

But why is this happening? Is it just because she is not proficient in controlling the divine fire?

Xia Ling was puzzled.

Duan Nanxiao just glanced at it and paid no more attention to it, as if he had known this would happen.

"Do you have a finished product of the elixir you made yourself?"

"some."

Xia Ling gave him a bottle of Fuling Pill and Qingxin Pill that he had made a few days ago.

Duan Nanxiao poured out the pill. Although the quality was good, it still contained a trace of poison, which was something that every alchemist could not avoid.

"Since you want to refine the Heavenly Grade Mysterious Sky Crystal into pure spiritual power, you must first solve the problem of the poison in the refined elixir."

He said so, but Xia Ling also had doubts, "Can erysipelas be completely eliminated?"

There is no such record in the history books of the continent, and even alchemists assume that it is normal for elixirs to contain a certain amount of toxicity.

Elder Guzhu did not mention this when he taught her.

It can be said that her alchemy skills were exactly as taught by Gu Zhu, but she had never thought about this issue in detail before.

“Others may not be able to do it, but for you who possesses the divine fire, if you can’t even do such a small thing, then what’s the difference between you and waste?” Duan Nanxiao said in a cold voice, as if it were a matter of course.

As soon as he finished speaking, a ball of blue flame suddenly appeared in his hand.

The moment it appeared, Xia Ling clearly felt a suffocating burning sensation.

He resisted the urge to retreat, raised his hand and summoned the divine fire to create a barrier-like circle of fire around himself, which made him feel better.

She had also seen the spiritual fire in Duan Nanxiao's hand in the treasure book.

It is called the Netherworld Fire, an external spiritual fire ranked number one on the Spiritual Fire List.

It has extremely strong destructive and corrosive power. Anyone who touches it will be torn to pieces. It can burn all visible and invisible existences.

The most important point is that it has the ability to evolve and will continue to evolve as the master's cultivation level improves. In other words, if Duan Nanxiao can become a god, it can also become a divine fire.

I didn’t expect that this unique and rare item actually belonged to Duan Nanxiao.

But Xia Ling didn't care about these. What she was most curious about was the word "trash" that Duan Nanxiao said.

"According to what you said, there is a connection between alchemy and weapon refining. Perhaps as long as I master the method of removing the poison from the elixir, I will also know the method of refining it, right?"

"Well, I'll demonstrate it once, and you watch carefully." Duan Nanxiao took out another young spiritual plant.

Under Xia Ling's gaze, the Netherworld Fire instantly enveloped it, but left a small gap in the center, using a trace of spiritual fire to devour the spiritual plant bit by bit until it was completely swallowed up.

The spiritual fire surrounding it only serves to provide a temperature blanket.

Xia Ling stared at the spiritual plant and found that the liquid that was quenched at the beginning had no impurities, but in the center it began to be stained with a trace of black liquid, which was the impurity.

At this time, Duan Nanxiao separated a small ball of spiritual fire and separated the black liquid from the Netherworld Fire.

Every time a trace of black liquid appeared, the small ball of spiritual fire that was separated out would engulf it and burn it to ashes.

This cycle continued, and soon, a drop of liquid that was pure enough without any impurities was extracted.

This level of processing requires more than just two things at once, as one must control the temperature, pay attention to the appearance and refining of impurities, and purify/burn the two separately.

To be able to do this, concentration is one thing. The most important thing is to fully control the spiritual fire. The consumption of spiritual consciousness and spiritual power is also extremely great, so a certain level of cultivation is required.

While Xia Ling was thinking, Duan Nanxiao took out another piece of top-grade crystal.

The method was the same, but his speed was even faster. It was obvious that the slow speed when tempering the spiritual plants just now was just a demonstration for Xia Ling.

In less than a minute, a ball of glowing white liquid floated in front of Xia Ling and was controlled by Duan Nanxiao to merge into her body.

Almost at that moment, Xia Ling felt his dantian heating up, and his bottleneck loosened a little.

The understanding of crystal stone can be said to be a higher grade spirit stone, its rarity and contained spiritual power are both higher than spirit stones.

And this ball of white light that merged into her body was the purest crystal source power after the impurities had been removed.

Xia Ling admits that he is currently unable to achieve this level, but this is limited to the present.

"Thank you, I know what to do." Xia Ling thanked Duan Nanxiao.

Duan Nanxiao said, "Just reach this level first, and then I will teach you how to refine it further. The last step is to refine a weapon. Don't forget that you still have the task of refining a spiritual weapon on your own."

"I will certainly not forget it." Xia Ling smiled at him and prepared to retreat. "Then I will go back to practice first, and come to visit you again when I have made some progress."

"Go ahead." Duan Nanxiao raised his hand to signal, then picked up the feather pen and continued to draw the unfinished weapon diagram.

As for Xia Ling... after getting the answer, he hurried back to his courtyard and started practicing.
