If I kill ghosts, I will become stronger: Invincibility starts with breathing

Chapter 257 Removing Impurities
Lu Yao's physical strength returned to its peak state.

It was already around noon, and everyone was going to eat, but Lu Yao didn't want to go for lunch. He just wanted to complete the second attempt.

The previous one was almost a success.

And he had a strong premonition in his heart, thinking that the next fusion process was likely to be successful.

It was precisely because of such a strong premonition that Lu Yao stayed.

The students left the classroom one by one, leaving only Lu Yao and his alchemy teacher in the classroom.

"This child is really hardworking. Class is already over, and he has to try again." The alchemy teacher said with emotion in his heart.

He came to Lu Yao's side, wanting to observe his second fusion process.

Lu Yao put the first medicinal herb into the medicine refining cauldron, and then covered the medicine refining cauldron.

He began to send his energy and blood into the alchemy cauldron.

The rune array on the tripod body was activated, and the temperature inside the tripod began to rise.

Although the fusion still failed last time, he also summed up the experience of failure, and he thinks he can do better this time.

In terms of Qi and blood output, as well as temperature control, there have been some minor adjustments this time compared to the last time.

Although there were many failures, Lu Yao became more proficient at controlling the entire fusion process as he practiced more times.

After 6 minutes passed, Lu Yao opened the alchemy cauldron and put the second medicinal herb into the alchemy cauldron.

Then, within about 21 minutes, Lu Yao successively put five different herbs into the alchemy cauldron in batches.

The power of his blood was also divided into 5 strands.

This is already the most critical moment.

The consumption of mental power began to increase.

When it was nearly 45 minutes, the five medicinal herbs were finally successfully refined separately, and the time between them being successfully refined was not more than one and a half minutes.

"The rest is the most critical moment."

Lu Yao became even more nervous. The last time he quarreled with each other, he failed at this crucial step.

However, this time there has been some progress. Last time, it took about 47 minutes to successfully extract 5 kinds of herbs.

But this time, the time when the five herbs were successfully refined was more than a minute earlier.

The extracts of 5 kinds of medicinal herbs are constantly approaching, they are mixed together, and under the action of high temperature, they are slowly refined into the shape of liquid.

The more critical the moment came, the more nervous Lu Yao became.

The temperature inside the alchemy cauldron reached its highest point.

A few more minutes passed, and the powdery extract was finally refined into a liquid.

A strong scent of medicine came from the medicine refining cauldron, which represented the success of the fusion process this time.

"Hey, it really succeeded!" The alchemy teacher who was watching from the side said with some surprise.

"Your progress is really a little bit, almost in the whole class, you have surpassed the progress of most of the classmates, and you are in the leading position."

He was really surprised, he didn't expect that the last student who entered their class was the one who made the fastest progress.

Originally, when I first came here, my foundation was very average, but within a short period of time, my progress surpassed most of my classmates.

"This child's talent is much higher than I imagined." He looked at the alchemy cauldron on Lu Yao's table.

This is just a low-level medicine refining cauldron, and it is considered the worst quality among the medicine refining cauldrons.

Among all the students in the entire medicine refining class, only Lu Yao's medicine refining cauldron was the worst.

But he surpassed the progress of most of the students with this stepless primary medicine refining cauldron, which is even more remarkable.

"Teacher, I have now completed the fusion of 5 kinds of medicinal materials, so can I enter the next step of study?" Lu Yao asked expectantly.

"Now you can barely complete the fusion of 5 kinds of medicinal materials, and you need to continue to practice a few times." The alchemy teacher said.

"In two days, I will start teaching you the next step."

"The step of fusion is the most difficult step in the process of refining medicine. You can complete this step now, but the following steps are relatively easier."

"I believe that with your current talent, you should be able to complete the next steps very quickly."

"Originally, I thought that apart from those students from the Alchemist Association, other students would need to enter the final stage and refine pills, at least until the next semester."

"It seems that according to your progress, I am afraid that you will be able to try to complete the refining of the pill in this semester."

"It's getting late now, it's almost 1:00 in the afternoon, you should hurry up and eat."

Lu Yao nodded, and immediately bid farewell to the alchemy teacher, left the classroom, and started walking towards the cafeteria of the college.

After finishing his lunch, he returned to his dormitory.

After putting the things in the dormitory, he left immediately.

When I came to the rune classroom, it was only 1:44 in the afternoon, and the teacher had not yet arrived in the classroom.

Lu Yao started to inscribe the runes very consciously.

In 7 minutes and 48 seconds, Lu Yao completed the inscription of a rune.

After completing the engraving of the 8 primary rune arrays, Lu Yao left the rune classroom.

He didn't go back to the dormitory, but went to the library for self-study.

Now after completing the fusion process of the 5 herbs, his heart is a little more relaxed.

At five o'clock in the afternoon, Lu Yao left the library and went to the cafeteria to eat.

Now he spends most of the time in the library alone, and the other partners spend their time training.

As the second key class challenge is getting closer, the time they spend in training is getting longer and longer.

After finishing dinner, Lu Yao returned to the dormitory.

He started to practice elementary sword skills, and he became more and more proficient in this set of sword skills. In the entire grade, there was no other student whose elementary sword skills could be more standard than his own.

It only took 3 minutes and 15 seconds for Lu Yao to complete the practice of this set of elementary sword skills.

After practicing elementary sword skills for an hour and a half, Lu Yao began to practice the fusion of five herbs.

In class, it took him nearly an hour to complete the fusion of 5 herbs.

On the second try, his experience was even richer.

It took him 57 minutes to complete the fusion process of five herbs.

In the evening, Lu Yao tried the fusion of the five herbs twice. In the second attempt, he was able to control the successful fusion time to 56 minutes.

In this way, another two days passed.

At 10:50 in the morning, Lu Yao had already arrived at the alchemy classroom.

Five minutes later, the teacher also came to the classroom. He asked the students to complete their own tasks, and then came to Lu Yao.

"We can start learning the next step today." The medicine refining teacher said, "The next two steps are relatively easy."

"The following two steps are called removing impurities and condensing the liquid medicine."

"The steps of removing impurities are very easy to understand, that is to control the temperature with the power of Qi and blood, and then remove the impurities in the liquid medicine."

"This requires your strong body control, and the control of qi and blood can do this."

"Your qi and blood power is not weak, and your body control ability is also very strong. I believe you can do this soon, so let's start to complete this step now."

Similar to the fusion of herbs, the removal of impurities also starts with the fusion of two herbs.

The teacher brought 6 medicinal herbs, each with two types.

"Next, I will start to show this step, you have to see clearly." The alchemy teacher reminded.

Then he opened Lu Yao's refining cauldron, and put the first herb into the refining cauldron.

In order to let Lu Yao see it more clearly, he did not cover the alchemy cauldron.

The rune array of the tripod body was activated, and the temperature inside the tripod was getting higher and higher.

After 1 minute, the teacher began to put the second medicinal herb into the alchemy cauldron.

It took only 4 minutes for the teacher to complete the fusion process of the two herbs.

The teacher's two qi and blood fused together, the temperature inside the cauldron began to rise, and the qi and blood were removing the impurities in the liquid medicine.

Lu Yao saw some black substances that were constantly being decomposed from the liquid medicine.

It took only 2 minutes, and the teacher had already completed the process of removing impurities.

"Okay, I have already shown this step, you can try it yourself, this is the easiest way to remove impurities, after you have completed the removal of impurities with two herbs, then you can try three herbs, four herbs or even The impurities of the five herbs have been removed," said the alchemy teacher.

"Wait until you've completed the five-herb impurity removal process, then you can move on to the next steps."

Lu Yao watched very carefully, and also listened very carefully.

"This step should not be very difficult."

After seeing the step the teacher rehearsed just now, Lu Yao was very confident in himself, and he didn't try the next step right away.

He still closed his eyes as usual, and began to recall the whole process shown by the teacher, and also thought about how he would need to complete this step later.

After thinking for about 6 minutes, Lu Yao opened his eyes.

He was ready to try it himself.

He put the first kind of herb into the medicine refining cauldron, and after covering the medicine refining cauldron, he began to send the power of Qi and blood into the medicine refining cauldron.

The rune array on the body of the tripod was lit up, and the temperature inside the tripod rose.

Six minutes later, Lu Yao opened the alchemy cauldron and put in the second herb.

The fusion process of the two requirements was not difficult for Lu Yao, and he completed this step very easily.

And it only took 18 minutes.

The two forces of qi and blood merged together, and the temperature inside the alchemy cauldron rose.

He controlled the power of qi and blood to remove the impurities in the liquid medicine.

But after persisting for about 8 minutes, there was a burnt smell coming from the alchemy cauldron, which meant that the attempt failed this time.

"There is something wrong with the temperature control, and the steps still need to be improved and optimized." Lu Yao summed up the experience of failure.

He closed his eyes again, thinking about the previous steps, and also thinking about what he did wrong, and how to change it next time.

About seven or eight minutes later, he opened his eyes and immediately began to try the second step of removing impurities.

It still took about 18 minutes to complete the fusion process of the two herbs.

It was time for get out of class to end, and the students left the classroom one after another. Lu Yao was too serious about completing his task, and didn't even realize that get out of class was over.

Then the two forces of qi and blood merged together, and he began to complete the last step.

With the experience of failure last time, let him do better this time.

After persisting for about 11 minutes, Lu Yao finally successfully completed the removal of impurities.

"Huh? What's going on? Why do I remove so few impurities!" Lu Yao said in surprise.

"It's already succeeded the second time, very good!" The medicine refining teacher praised.

"You don't have to compare with me, the more impurities you remove, the easier it is to refine higher quality pills."

"You have just completed this step now. When you improve your refining level in the future, you will naturally be able to remove more impurities."

"There are still a few herbs left, so you can take them back and practice. You can try to remove impurities from three kinds of herbs tomorrow."

It was past 12:00, Lu Yao bid farewell to the teacher, left the classroom, and went to the cafeteria to have lunch.

The next day, the teacher began to teach him the process of removing impurities from the three herbs.

This step is more complicated, but it is not difficult for Lu Yao. .

When he tried for the 5th time, he had successfully completed the process of removing impurities from the three herbs.

The next step is to remove the impurities of the four herbs, and the difficulty increases again.

This time, it was not so easy for Lu Yao to complete this step.

The six medicinal herbs given by the teacher have all been consumed, and he still has not completed the steps of removing impurities from the four medicinal herbs.

The time soon came to February 5th.

At 07:30 in the morning, Lu Yao had already woken up early.

After washing up, several friends came to his dormitory one after another.

They left the dormitory area together and went to the cafeteria to have breakfast.

It was time to get the pills again today, so after eating breakfast, they went directly to the Qi training classroom.

Sure enough, it was exactly as they had imagined before. When the teacher came, he was holding a big black cloth bag in his hand. No need to think too much, everyone knew that what was inside must be blood pills.

The teacher came to the podium and put the cloth bag on the table.

"Now it's time to get the pills again, and the next key class challenge is less than a month away." Teacher Liu said.

"I hope that in the next month, you will also be able to receive pills in this classroom."

The teacher's words made some of the students below become a little nervous.

The last key class challenge made these students realize that they are not safe.

The original relaxed state of mind has also changed.

"So without further ado, I will start distributing the pills to everyone now, and the students whose names I read will come up and get your pills." Teacher Liu said.

Then the teacher began to roll the roll one by one, and the students whose names were called walked up to the podium with happy faces and received their own pills.

In less than 10 minutes, the teacher had distributed the pills to everyone.

"My business has been done, so everyone can leave. I will notify you when the registration list for the next key class challenge comes out." Teacher Liu said.

After receiving the pills, everyone started to leave one after another.

Lu Yao and several partners also left the classroom and returned to their dormitory.
