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

Chapter 22 Grey Airflow
Being able to successfully condense the power of Qi and blood, Lu Yao was in a very good mood.

Although his current strength is still very weak.

But at least with the power of blood, he already has the capital to become stronger.

Lu Yao began to try to continue practicing Tempering Body Fist.

He found that his speed of completing Body Tempering Fist had become faster.

And when he was practicing Tempering Body Fist, he could feel a gray air current in his dantian, which seemed to be ready to move.

It startled him.

He recalled the previous scene in his mind.

He remembered that the gray air flow entered his dantian from the ghoul he killed.

"What is this gray air current?" Lu Yao thought with some worry in his heart, "It's coming from the ghoul, it can't be something unclean!"

But because he was going to have dinner soon, he didn't have time to study this gray air current.

After five o'clock, he, Du Tong and Zhan Yu went to the cafeteria to have dinner.

Then the three of them came to the training ground together.

Originally, after dinner, Du Tong and Zhan Yu went back to the dormitory to rest.

But as the assessment of the ghost slaughter team approached, the two also felt a sense of crisis in their hearts.

They want to take advantage of the last few days to work harder.

Du Tong and Zhan Yu were practicing Tempering Body Fist.

And Lu Yao sat cross-legged on the ground.

He was going to try to control this gray air current in his dantian.

He found that when he was practicing Tempering Body Fist, this gray air current became extremely active.

The power of his blood and his brain seemed to have a strong desire for this gray air current.

It's like the feeling of a hungry person seeing food.

"Why is there such a strange feeling?" He was both curious and worried.

He used his consciousness to control the gray air flow in his dantian, trying to slowly strip him from his body.

The gray air flow is also slowly flowing outward along his dantian.

Suddenly, the power of qi and blood in the flesh came a suction.

Under the influence of the suction force, this gray air flow entered Lu Yao's body.

This Lu Yao was taken aback.

But the changes that followed shocked him.

The power of qi and blood seems to be constantly merging with a gray air current.

The moment the gray air flow entered the body.

It was absorbed half by the power of Qi and blood.

After the power of qi and blood absorbed this half of the gray air flow, there was a very large increase.

Lu Yao felt that his strength had increased significantly.

"My qi and blood power has increased so much all of a sudden." Lu Yao thought in surprise.

He couldn't help but want to test his blood value now.

"This gray air flow can actually increase my energy and blood." Lu Yao's heart was beating violently.

He knew what a terrible effect it was.

Once he has more gray air currents, his blood power will continue to grow.

"How did this gray air flow come from?" Lu Yao guessed in his heart.

"Is it because I killed that ghoul before that I got this black air current?"

"So as long as I keep killing ghouls, I might still be able to get the gray air current."

"But I don't know if this gray gas flow can be obtained from all dead ghouls, or if I need to kill ghouls myself to get this gray gas."

These thoughts in his mind are just his guesses.

To truly confirm his guess, the only way to get the answer is to kill a ghoul again.

"Maybe I have a way to become stronger quickly." Lu Yao thought expectantly in his heart.

After all, he came from another world, and he could quickly accept such things.

The power of qi and blood can only absorb half of the gray air flow at the moment when the gray air flow merges.

The speed of absorption later became slower.

The power of his blood is also constantly growing.

Such growth feels very obvious.

"I don't know how much qi and blood power I have now. I feel that at that moment just now, I can at least increase the qi and blood value by 1 power." Lu Yao guessed.

As early as when they were about to eat, Teacher Qinglong had already asked the villagers to remove the dynamometer from the training ground.

He can't test his own strength now, which makes him feel a little regretful.

Lu Yao opened his eyes and stood up.

He continued to practice Tempering Body Fist.

It may be because the power of qi and blood has increased.

The speed at which he completed the Body Tempering Fist was a few minutes faster again.

This surprised him a little.

"The speed at which I can complete this set of Body Tempering Fist is no longer slower than that of Zhan Yu." Lu Yao thought in his heart, "After I absorb the remaining gray air flow, I can complete it a little faster. It's time to surpass Zhan Yu."

He found that when he practiced Body Tempering Fist, the gray air flow was absorbed faster.

This made him more serious when practicing Tempering Body Fist.

At eight o'clock in the evening, Du Tong finally couldn't stand it anymore.

After a long period of practice, his physical strength was very exhausted, and he was now panting.

"It's already eight o'clock, let's stop practicing here today." Du Tong suggested, "My physical strength has been exhausted."

"It's over so early?" Lu Yao still had some thoughts.

Although in the process of practicing Tempering Body Fist, his physical strength and blood are also constantly being consumed.

But as the gray air flow decreased, his physical strength recovered faster and faster.

Although he also practiced for several hours, he didn't look tired.

"Lu Yao, are you sure you've just condensed your energy and blood? Why are you so strong?" Du Tong exclaimed, "We've been training for so long, don't you feel tired?"

Du Tong glanced at Zhan Yu.

He was currently practicing Tempering Body Fist in a muffled voice.

His Qi and blood power is the highest among the three of them, and it is much higher than them.

But even Zhan Yu's forehead was slowly sweating at this time.

Only Lu Yao looked very relaxed.

"Maybe it's because I used to train my body at night before, and I'm used to this rhythm." Lu Yao gave an explanation.

"Since you are tired now, let's end today's training."

Lu Yao trained so late in the past, and he also exhausted his body.

That's why he died after being beaten up by the three senior brothers, and he occupied this body.

Now that Lu Yao's strength has become stronger, he can also practice for a longer time.

He knew that this was the first time Du Tong practiced for such a long time, and his body still had some discomfort.

He also complied with Du Tong's request. This time, he ended earlier and went back to the dormitory to rest.
