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

Chapter 259 Concentration of Medicinal Solution
Now that a burst of gray air has just been consumed, Lu Yao's memory, comprehension, and comprehension abilities are at their strongest.

Some of the knowledge points I learned before, and the things I didn't understand, are almost mastered.

He doesn't want to waste any time.

The time for serious study passes very quickly, and soon it will be 5:00 in the afternoon.

He left the library and went to the cafeteria to have dinner alone.

When he returned to the dormitory, the other partners were still training hard.

Lu Yao also started practicing elementary sword skills. As he practiced this set of elementary sword skills repeatedly, his understanding of this set of elementary sword skills was also deepening.

In the process of practicing, he is also constantly correcting his substandard movements, making this set of elementary sword skills more perfect and complete.

After practicing elementary sword skills for nearly an hour, Lu Yao began to practice water source combat skills.

Practicing water source combat skills at this time also made Lu Yao's progress very fast.

He could feel that his understanding of water combat techniques was deepening, and he became more sensitive to the water element in the air.

"My water source combat skills have also improved some understanding. In the past, when I performed the first form of water source combat skills, I could only produce 10 drops of water, but now I can condense 11 drops of water. This makes me The attack range can be wider, and the consumption of energy and blood has become smaller." Lu Yao thought to himself.

The more water droplets that can be condensed, the more advantageous it will be in group battles.

Sometimes the enemy is not just one person, there may be a group of enemies.

After practicing the water source combat skills for another hour, Lu Yao's energy and blood were almost exhausted, and he did not accompany his partners for actual combat training.

After resting for a while.

He started the herbal impurity removal process.

In the previous class, it took him about an hour to complete this step.

And after completing this step, his energy and blood were almost exhausted.

This is also because he is not very familiar with this step, but now that he has succeeded once, it is only a matter of time before he is familiar with it.

In his mind, he has recalled the previous successful process again, and he is also thinking about the steps that he did not do well before, and the steps that can be improved next time.

Lu Yao opened the medicine refining cauldron, put the first herb into the medicine refining cauldron, then covered the medicine refining cauldron, and 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 was getting higher and higher.

The first type of herb was being refined rapidly, and after about 1 minutes passed, the alchemy cauldron that Lu Yao was going to open began to put the second type of herb into it.

The power of his qi and blood also split into two streams at the same time.

The more qi and blood power is diverted, the more mental power will be consumed.

But fortunately, he had consumed a stream of gray air before, and the effect of the gray air was still there.

Although mental power is consumed quickly, it is also replenished very quickly.

What he needs now is to practice the whole process more familiarly while the effect of the gray air current is still there.

After the gray air flow is completely consumed, the effect is gone, and he can only complete this step through the experience accumulated before.

The whole process is still very difficult for him, and he still maintains a very cautious attitude, but he feels much better than when he succeeded for the first time.

Recently, he has also had a successful experience.

In about 20 minutes, Lu Yao had put 5 different herbs into the alchemy cauldron one after another.

His qi and blood were also divided into five strands at the same time, and each strand of qi and blood was controlling a different kind of herb.

This time, it only took more than 30 minutes, and 5 kinds of medicinal materials have been successfully refined.

Then five qi and blood forces controlled five different herb extracts to approach.

When a cloud of dark green liquid appeared in the alchemy cauldron, it meant that the extracts of these several herbs had been fused successfully.

Then there is one more step left.

The five qi and blood forces merged into one, and the temperature inside the cauldron rose again.

Under the control of the power of qi and blood and high temperature, the impurities in the liquid medicine are slowly being removed.

This time the process lasted 55 minutes.

"It succeeded again." Lu Yao also breathed a sigh of relief with a smile on his face.

The whole process is very difficult and very labor-intensive.

After resting for a while, his qi and blood power recovered a bit, and he started the second process of removing the herbal impurities.

It wasn't until almost 11:00 that Lu Yao stopped continuing.

In this way, another day was separated.

At 10:30 in the morning, Lu Yao bid farewell to his friends and started to go to the alchemy classroom.

At about 9:00, the teacher came into the classroom.

He got the seat next to Lu Yao.

"You have completed the process of removing impurities from the five herbs, and the next step is called liquid concentration." The alchemy teacher said to Lu Yao.

"During this step, you need to start with the concentration of the medicinal solution of two herbs, and complete until the concentration of the medicinal solution of five herbs is successful."

"The most important thing in this process is to control the level of temperature, and the output of Qi and blood power."

The teacher still brought 6 herbs this time.

"Then let's start the process of concentrating the two medicinal herbs first." The medicine refining teacher reminded.

The day before yesterday, Lu Yao successfully completed the process of removing impurities from 5 kinds of herbs. Originally, the teacher asked Lu Yao to come to the next step in two days.

However, in order to make the progress faster, Lu Yao asked the teacher yesterday to let him start learning the next step today.

And yesterday, he had already consumed all the remaining medicinal herbs, and also completed several exercises in the process of removing impurities from the medicinal herbs.

The reason why he wanted to learn this step a day earlier was also because he had absorbed a gray air current the day before yesterday, and the effect of the gray air current was still in his brain.

His current memory, comprehension ability, and comprehension ability are all better than usual.

If you study now, the progress will be faster.

The teacher opened the medicine refining cauldron, and then put the first kind of herb into the medicine refining cauldron.

Lu Yao is already familiar with the fusion process of herbs, and the teacher has completed the fusion process of the two herbs in less than 3 minutes.

After the impurities in the liquid medicine were removed, the teacher increased the output of energy and blood again, and the temperature inside the cauldron rose again.

As long as you can see that the liquid medicine is constantly shrinking.

The liquid became more and more viscous.

After 3 minutes, the fragrance of the medicine became more intense, and Lu Yao saw a mass of brown-black solid matter in the medicine refining cauldron.

This is the product after the liquid medicine is concentrated.

"Successful! The difficulty of this step is actually not too great. I believe you can complete this step very quickly." The alchemy teacher encouraged.

"Now you can start trying it yourself."

The teacher didn't leave, but still stood by Lu Yao's table, wanting to watch him try.

Lu Yao closed his eyes and began to recall every step of the teacher before.

His current mental strength, memory, and character abilities are far superior to those in the past, which allows him to recall each step more clearly and understand it faster.

"You can try it yourself!" Lu Yao thought in his heart.

Five minutes later, Lu Yao opened his eyes. He opened the alchemy cauldron in front of him, and also put the first herb into the alchemy cauldron. The power of qi and blood is conveyed in the medicine cauldron.

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

The combination of the two herbs is already very easy for Lu Yao now.

Although he didn't practice for a long time, he practiced quite a lot, and the gray air flow was consumed to make his practice better.

It only took him 17 minutes to complete the fusion process of the two herbs.

In the process of removing impurities, he was a little more serious.

After 25 minutes passed, Lu Yao also successfully removed the impurities in the liquid medicine.

Then comes the most critical step.

Lu Yao increased the output of energy and blood, and the temperature inside the alchemy cauldron rose again.

Now his brain is running fast, thinking about every step, and constantly changing the output of Qi and blood power, as well as the control of temperature.

The liquid medicine is slowly concentrating.

He was very careful throughout the process.

He could see the liquid getting thicker and thicker.

Another ten minutes passed, and the liquid medicine was concentrated into a brown-black solid substance. Lu Yao knew that he had succeeded in this step.

"Huh? Since the first attempt was successful, even though it was only a fusion step of two herbs." The medicine refining teacher at the side said with some surprise.

"Your progress is a little faster than I expected. Tomorrow you can try the process of concentrating the three herbs."

get out of class was over in less than 10 minutes, and his remaining qi and blood power was not enough for him to complete the second concentrated practice of the two herbs, so he stopped trying.

He simply closed his eyes, continued to recall the previous successful steps, and also thought about what needs to be improved in the next attempt.

Soon it was time for get out of class to end, he bid farewell to the teacher and left the alchemy classroom, then went to the cafeteria for lunch.

4 Herbs left.

After he finished the rune class, he went back to the dormitory to practice the steps of concentrating the herbs.

At 8:20 in the evening, he finally consumed all the herbs that the teacher brought today.

And the time he completed the concentration of the two herbs can be controlled at about 37 minutes.

On the second day, the teacher asked him to try the enrichment process of the three herbs again.

The process of concentrating the three herbs is a little more difficult.

Lu Yao didn't succeed in one shot, he tried three times before finally successfully completing the process of concentrating the three herbs.

It took him two days to practice the concentration steps of the three herbs.

Then came the concentration step of the 4 kinds of herbs, and the difficulty increased again.

In this small step, it took him a little longer. He tried a total of nearly 30 exercises before he successfully completed the step of concentrating the 4 herbs.

Then comes the concentration step of the five herbs.

The difficulty increased a bit, and it took more than a week, but Lu Yao did not complete the fusion steps of the five herbs.

However, every time he fails, he will summarize his own failure experience, and he is also thinking about what can be optimized.

He is getting closer and closer to success.

On the morning of May 5, the students in the exercise class informed Lu Yao that they would go to the classroom the next day.

"It seems that the second key class challenge will be announced soon." Lu Yao thought to himself.

Another day passed, and at 7:30 in the morning, Lu Yao woke up naturally.

After washing up, he and a few partners left the dormitory area and went to the cafeteria to have breakfast.

Then they came to the body training classroom together.

The discussion in the classroom was very noisy.

The students seemed rather nervous. After all, it is already the end of May. Needless to say, everyone can already guess the purpose of the teacher asking them to come to the classroom this time.

Especially for those students who are weaker, their pressure is the greatest.

"We should have performed well last time. We don't know if we will be challenged in this key class challenge." Du Tong said.

"Don't worry, you will definitely be challenged. After all, in the last challenge, although the power of blood and blood you tested has improved a lot, the power of blood and blood is still at the bottom of the entire key class, which is considered a relatively good challenge. Yes." Lu Yao said.

"Maybe for many students in ordinary classes, you were just lucky last time."

"And in the last key class challenge, there were only a few ordinary class student challengers, and only they knew your performance when you came to the training ground."

"The other students in the ordinary class just heard about the strength of your Qi and blood in the last test, and your actual combat results."

"They don't think that you are strong, they only think that your challenger is weak."

For students in ordinary classes, the resources in key classes are one of the reasons that attract them, but what attracts them more is the honor of students in key classes.

The students who were able to be admitted to Guodu College all had good financial conditions, and the registration fee did not put any pressure on them.

As long as there is a little bit of confidence in the students, they will choose to sign up for the challenge.

"I don't know how many students challenge our key class this time?" Lei Ming asked curiously.

"Last time, more than 10 students were challenged in our class, and the number of students challenged this time may not be less than last time."

"Then I don't know, but I heard from them that the first key class challenge was the time when the number of challengers was the largest." Lu Yao said.

"There shouldn't be more challengers in this second key class challenge than in the first one, right?"

In Lu Yao's heart, he didn't feel any pressure, nor any sense of tension.

For him, no matter whether someone challenges him or not, he is very confident in his own strength.

It has been almost half a year since he left school, and his energy and blood power has increased. Although it is not a lot, his actual combat ability has increased tremendously.

After consuming the gray air flow, he had a deeper understanding of primary sword skills.

Now in about 2 minutes and 13 seconds, Lu Yao can complete a complete set of elementary sword skills.

The faster one can complete the primary sword skill, the stronger the sword skill's power will be.

Water source combat skills need to store energy and consume a lot of energy and blood.

Although the primary sword skills are less powerful, they consume much less energy and blood, allowing him to last longer in battle.
