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

Chapter 253 Consumption of Gray Qi

At 8:20 in the morning, Lu Yao finished his breakfast and returned to the dormitory.

He started practicing primary combat skills.

In 4 minutes and 35 seconds, Lu Yao successfully completed all the moves of elementary sword skills.

With continuous practice every day, the speed at which he can complete elementary sword skills is also increasing.

After completing an hour of elementary sword skills practice, Lu Yao began to practice water source combat skills.

The water source combat skill consumes the most energy and blood power, and after completing the two combat skills of the previous year, Lu Yao has already consumed nearly [-]% of his energy and blood power.

Lu Yao sat cross-legged on the ground, closed his eyes, and began to practice the intermediate breathing method, and he was also using the breathing method to recover the exhausted physical strength.

When the power of qi and blood recovered to [-]%, Lu Yao began to use the water source as a medium again to continue practicing the first four moves of the water source combat technique.

Lu Yao didn't stop practicing until 10:40.

He bid farewell to his companions, left the dormitory, and started to attend classes in the alchemy classroom.

When it was almost 11 o'clock, the alchemy teacher came to the classroom.

"Now you can start to try the fusion of 4 kinds of herbs. This time the difficulty of fusion has increased again." The alchemy teacher came to Lu Yao and said to him.

"To complete the fusion of the four herbs, you need to practice and try more times."

Lu Yao nodded, and he also understood this truth in his heart.

"Now I'm going to show you the process, you have to watch carefully." The alchemy teacher reminded.

Lu Yao concentrated his mental strength and began to watch the fusion process of the alchemy teacher seriously.

The teacher opened Lu Yao's refining cauldron. At the beginning, he still put the first medicinal material into the refining cauldron, which is also the most resilient medicinal material.

The teacher did not cover the alchemy cauldron, this is also to make the whole process more clear.

The reason why ordinary pharmacists cover the cauldron to refine pills is also to prevent the loss of the efficacy of the medicine. After covering the cauldron, the medicinal materials in the medicine cauldron can be heated more evenly.

After 1 minute passed, the teacher put the second herb into the cauldron.

His energy and blood split into two strands, and each strand of energy and blood controlled a kind of medicinal herb.

Lu Yao was also remembering the whole process.

With the fusion of 4 kinds of herbs, the whole process becomes more complicated, and there are more details.

It is impossible to remember all these processes in his mind. Even with Lu Yao's current memory, he can barely remember [-]% of the steps.

The teacher operated the whole steps very quickly, and the whole process was very smooth.

In the case of not covering the tripod, the difficulty of fusion is actually even greater.

But for teachers, this step is still very simple and easy.

Then the third medicinal herb was put into the medicine cauldron, and then the fourth medicinal herb.

In less than 4 minutes, the teacher had already put all four different medicinal herbs into the alchemy cauldron.

The order of placing these herbs is still according to the toughness and hardness of these herbs.

Just after 5 minutes, the four herbs were refined into a powdery substance.

Then the extracts of the four medicinal herbs kept approaching, and were refined into a dark green medicinal liquid under high temperature.

The whole process was completed in less than 7 minutes.

This is because the teacher deliberately slowed down the speed in order to let Lu Yao see more clearly.

"Okay, I have completed the fusion of four kinds of medicinal herbs, pay attention to temperature control, your current blood power is incomparable with mine, and you don't need to output like me, you follow your own habits , it’s enough to output the power of Qi and blood.” The alchemy teacher reminded.

"The most difficult thing to control in the fusion of four herbs is the blood output and temperature control of each herb."

"You need to make the time difference between these four herbs to complete the extraction less than 4 minutes, so that it is not easy to fail."

"If it takes more than 2 minutes for the four herbs to be successfully extracted, the herb that is successfully extracted first will be easily burned by high temperature."

Lu Yao was listening to the teacher's explanation very seriously, and the teacher explained all the details clearly.

He will repeat and repeat the more important steps.

"Based on your current level of refining medicine, it is already very good to be able to divide the output of Qi and blood power equally." Said the medicine refining teacher.

"When your qi and blood power is higher and your qi and blood control is better, then you can try a more difficult refining process."

"You not only need to split the energy and blood into several strands, but each strand of energy and blood also needs to have a different output."

"Only if you can do this, can you extract several different herbs at the same time, so that they can be fused at the same time."

"For you to complete this step, there is still a long way to go."

"Now you can try to complete the fusion of 4 kinds of herbs by yourself."

This time the alchemy teacher brought six servings of herbs, allowing Lu Yao to complete the fusion of four herbs six times.

Lu Yao closed his eyes, and began to recall the entire steps that the teacher showed before in his mind.

There are too many details, and Lu Yao can only remember a few steps.

"Forget it, let's try first!" Lu Yao thought in his heart.

Then he opened the medicine refining cauldron in front of him, and put the first medicinal herb into the medicine refining cauldron.

Lu Yao began to send the power of Qi and blood into the alchemy cauldron,
The rune array on the body of the tripod was lit up, and the temperature inside the tripod rose.

When controlling a herb, Lu Yao still felt very relaxed.

At 8 minutes, Lu Yao opened the alchemy cauldron and put in the second herb to be refined.

Lu Yao's energy and blood split into two streams.

Lu Yao was also able to control two different herbs with ease.

After more than 4 minutes, Lu Yao added the third herb.

The power of his qi and blood was divided into three strands again.

Three qi and blood forces control three different herbs.

This made his qi and blood power consumed faster, and his mental power was also consumed a lot.

The control of the three qi and blood forces made him a little cautious.

After more than three minutes, Lu Yao put the last herb into the alchemy cauldron.

The power of his qi and blood was divided into four strands, which required stronger control of qi and blood.

Lu Yao felt a little powerless.

Controlling the extraction of 4 kinds of medicinal herbs consumed a lot more mental power.

Just after putting the fourth medicinal herb into the alchemy cauldron, less than a minute later, there was a burnt smell coming from the alchemy cauldron.

Indicates that the fusion process has failed.

"Hey, it's really much more difficult. The power of Qi and blood is divided into four parts, and it's even more difficult to control the temperature." Lu Yao thought helplessly in his heart.

"In just such a short period of time, [-]% of the power of Qi and blood has been consumed, and the spiritual power feels like it is about to be exhausted."

"It seems that I can only practice more when I go back."

Before he completed the practice of herbal fusion, it was all done in the classroom.

Now the difficulty of merging the four herbs has increased. In order to complete this step as soon as possible, he had to prepare to continue practicing this step when he returned to the dormitory.

After the refining course was over, Lu Yao left the classroom with the refining cauldron and herbs, and went to the cafeteria to have lunch.

After returning to the dormitory, Lu Yao began to continue to try the fusion steps of the four herbs.

The second time is still a failure.

Lu Yao was also mentally prepared, and he was not depressed.

After finishing dinner and returning to the dormitory at night, he began to try the fusion of four herbs.

The third attempt was still a failure.

Then there was the fourth attempt at fusion, which still failed.

"It still doesn't work, there are still two fused herbs, try again in class tomorrow." Lu Yao thought helplessly in his heart.

"The alchemy teacher asked me to complete this step within a month. With my current progress, I definitely cannot complete this step within a month."

"When I try it tomorrow, I can consume a stream of gray air, which will allow me to complete the fusion of the four herbs faster."

Although he failed in 4 consecutive attempts, he still made progress.

To complete the fusion of 4 kinds of herbs, there is still a long way to go, and many times of practice is required.

At 10:40 in the morning, Lu Yao left the dormitory and went to the alchemy classroom.

When Lu Yao arrived in the classroom, the teacher hadn't come to the classroom yet.

"Complete the fusion of herbs first, and then use a puff of gray gas. After a few minutes of rest, start the second attempt." Lu Yao thought to himself.

Before the teacher came to the classroom, Lu Yao opened the alchemy cauldron and put the first medicinal herb into the alchemy cauldron.

He had tried the fusion process 4 times yesterday, and although he was still a loser, he had already accumulated some experience.

At least in the previous steps, he completed it more smoothly than yesterday.

In less than 20 minutes, he had put all four kinds of medicinal herbs into the alchemy cauldron one after another.
Lu Yao's energy and blood also split into four strands.

He could barely control the four qi and blood forces now, but with the consumption of mental power, it became more and more difficult for him to control these qi and blood forces.

After putting the fourth medicinal herb into the alchemy cauldron, another 5 minutes passed, and Lu Yao felt that his mental power was almost exhausted.

Although he still has some energy and blood left, it is difficult to control the output of the four energy and blood.

In the medicine cauldron, one of the energy and blood force suddenly dissipated, and in less than 10 seconds, there was a burnt smell from the medicine cauldron.

This time he persisted for a little longer, but still ended in failure.

"Sure enough, it still failed!"

His blood power has consumed more than 9%.

Mental power is also exhausted.

He felt very tired all over, and even felt a little dizzy in his brain, and his vision became blurred.

"The gray airflow can be used now." Lu Yao thought to himself.

His consciousness sank into the dantian, controlling a gray air flow in the dantian that began to flow to the brain.

When the gray air flow approaches the brain, the brain instantly absorbs half of the gray air flow.

Nuo Yao felt that the mental power that had been exhausted was replenished at this moment. Not only that, but he also felt that the memory that was somewhat vague before became clear in an instant.

He didn't remember clearly the fusion process of the 4 kinds of herbs shown by the teacher yesterday, but now it seems to be engraved in his mind, and every step has become very clear.

Even the content that has been learned before is slowly becoming clear.

He could feel his comprehension ability, and his comprehension ability had improved several times than before.

There are some places that I don't understand, and now they suddenly become clear.

Even the recovery speed of his qi and blood power was twice as fast as usual.

After resting for about 10 minutes, his energy and blood had almost recovered.

"There is the last herb left, you can try the last fusion step." Lu Yao thought to himself.

In this attempt, he became more confident, and he felt that all the previous steps had become a deep impression in his mind.

Because of the enhancement of his comprehension ability, let him know how to correct those wrong steps and how to control the power of Qi and blood, so that the whole process can become smoother and the power of Qi and blood can be consumed less.

Lu Yao opened the medicine refining cauldron and put the first herb into the medicine refining cauldron.

Just after 7 minutes this time, Lu Yao put in the second herb.

The power of his qi and blood split into two streams.

After more than 4 minutes, Lu Yao put in the third medicinal herb, and the power of Qi and blood was also divided into three strands.

In less than 17 minutes, Lu Yao had already put 4 different herbs into the alchemy cauldron.

Lu Yao's energy and blood split into four strands.

He felt that his brain became more refreshed. Although the mental power was constantly being consumed, due to the effect of the gray air flow, the mental power was also being consumed and replenished at the same time.

His comprehension ability has become stronger now, allowing him to better control the output of these qi and blood forces.

The strengthening of the control over the power of Qi and blood means that the consumption of the power of Qi and blood has become smaller, allowing him to maintain the output of Qi and blood for a longer period of time.

"The refining is almost successful!" After persisting for 40 minutes, Lu Yao felt that the refining step was almost completed.

There was joy on his face.

But even if the consumption of energy and blood power is smaller, maintaining such a long-term output of energy and blood still makes him feel that his physical strength is too great.

45 minutes passed, and the four medicinal herbs were finally extracted successfully.

Then Lu Yao controlled the extracts of the four medicinal herbs, making them keep approaching.

But in less than 2 minutes, the power of Qi and blood in the cauldron quickly collapsed.

Lu Yao's energy and blood had been exhausted again.

"It's a pity!" Lu Yao thought helplessly in his heart.

"If my energy and blood were stronger, I should be able to complete the fusion of the four herbs."

The reason why he failed this time was also because his energy and blood were not strong enough.

Of course, if he had better control over the power of Qi and blood, and could make the output of Qi and blood during the whole process smaller, then even if his power of Qi and blood was not strong enough, he could still complete this step.

As long as he can achieve one of the two points, then he can complete the fusion of the four medicinal materials.

"Teacher, I have used up all the herbs!" Lu Yao said to the medicine refining teacher next to him.

It was already past the end of get out of class time, he was the only student in the whole class, and the alchemy teacher had been watching his fusion process by his seat.

"I'll bring you some more tomorrow," said the alchemy teacher.

"I saw your whole process just now. You have done a very good job now. I believe it will not be long before you complete the fusion of the four medicinal materials."

"Originally, I asked you to complete the fusion of the four medicinal herbs within a month. I still felt a little embarrassed for you. Now it seems that I underestimated your talent."

Lu Yao felt a little helpless in his heart. The teacher did not underestimate him, but overestimated him.

The reason why he has made such progress is not because of his amazing talent, but because he has consumed a stream of gray air.

He now has 23 gray streams left, which makes him a little heartbroken.
