After cultivating for a week, Cao Qi opened his eyes and felt that his cultivation speed was much faster than before, the spiritual energy was unimpeded throughout the meridians, and the speed of absorbing spiritual energy from the outside world was also faster.

If the speed at which the little one's psionic energy used to run in his body was that of a person walking.

The speed of the spiritual energy after the last I Ching cleansing was a 100-meter sprint.

And this time, after the I Ching cleansed the marrow, the speed of the spiritual energy can be said to be riding a fast-moving bicycle.

'No wonder Ouyang Keji's level is so high!' It seems that the cultivation resources of rich people are different!"

"Since the cultivation speed of spiritual energy is so fast, let's try to perceive the body's qi and blood, and after this I Ching cleansing, will it be easier to perceive the body's qi and blood?"

As soon as he thought of this, Cao Qi closed his eyes again to sense the existence of qi and blood in his body.

Soon, he sensed that the blood was flowing to produce a colorless wave, just like the heat waves we see on the ground in summer when the weather is too hot, they are slowly released outward, and when they pass through the muscles, they are absorbed by the muscles.

'This should be the initial state of the body's qi and blood!'

This discovery made Cao Qi a little ecstatic, and he was finally able to sense the existence of his body, qi and blood.

Then, Cao Qi slowly clenched his fist and raised his right hand, and the qi and blood in the surrounding muscles converged to the shoulder deltoid muscle.

When you raise your hand to shoulder height, pull your hand back to make a charging shape, and the qi and blood that gather in the deltoid muscle of the shoulder begin to flow to the biceps.

Finally, in the process of swinging the arm forward, the body's qi and blood flow from the biceps to the forearm muscles, and then to the fist.

After confirming that he really felt the qi and blood of his body, Cao Qi calmed down instead, and he began to ponder.

'Why does the body, qi and blood emanate from the blood?'

'Blood is ejected from the left ventricle and flows to the capillaries of the whole body through the aorta and its branches at all levels, where it exchanges substances with the interstitial fluid, supplies oxygen and nutrients to the tissue cells, transports carbon dioxide and metabolites, and the arterial blood becomes venous blood, and then flows back to the right atrium through the confluence of the superior and inferior vena cava through the surface fat at all levels, and this cycle is the systemic circulation. '

Blood ejects from the right ventricle and flows through the pulmonary artery to the pulmonary capillaries, where it exchanges with alveolar gas to absorb oxygen and excrete carbon dioxide, and the venous blood becomes arterial blood, and then flows back to the left atrium through the pulmonary vein, and this cycle is called the pulmonary circulation. '

'Could it be that the so-called physique, qi and blood are the material energy in the body?'

Therefore, the colorless waves produced by the previous perception of blood flow are material energy waves.

''And the way to cultivate the body's qi and blood is to follow the way the body circulation and the lung circulation work?'

Cao Qi immediately closed his eyes to look inside the heart, and he followed the blood pumped out of the left ventricle all the way along the systemic and pulmonary circulation paths.

He found that this was indeed the case, and that the blood had been releasing waves of material energy since it came out of the left atrium, and it was not until after the exchange of matter with the interstitial fluid that this wave of material energy disappeared.

That means that after the top-grade myelin cleansing pill I ate today, after being digested by gastric juice, part of the medicinal power entered the heart.

Then, with the circulation of blood, his own blood vessels were also cleaned up and improved, so he could feel the existence of qi and blood in his body after this I Ching cleansing.

Then the next thing he has to do is to familiarize himself with the way his body, qi and blood operate in each of his movements.

'Could it be that the Eighteen Palms of the Descending Dragon and the Turtle Sect Qigong Wave were activated after mastering the material energy waves?'

'Huh... Could it be that Sun Wukong and Kling have been forced to squeeze their bodies by the Turtle Immortals when they were children, just to make their muscles stronger, denser, and able to store more material energy?'

'Nima... Looks like that's really the case!'

It seems that the purpose of physical training is to allow the muscles to store more qi and blood to compress the body. '

'Well, it must be so. '

'I'll go... That's not if I have cultivated my physique, qi and blood, and I can become a Super Saiyan. '

Thinking of this, Cao Qi couldn't help laughing.

"Cao Qi, your uncle, is still smirking outside the door! Did you get the stinky sludge on Lao Tzu's body?"

Li Xiang's roar came from inside the dormitory.

"Yo... Shoko, you're awake!"

Cao Qi opened the door and entered the dormitory, and saw Li Xiang, who was in darkness, standing under the bed, staring at him with a fierce light.

"What's going on!?"

"Calm down, listen to me, it's none of my business, I'll go and show you the evidence. ”

Saying that, Cao Qi asked the washing machine to go, came to the washing machine, took out his clothes and pants and bed sheets that had not been washed from the washing machine, and shook them at Li Xiang.

"These black sludges are the impurities in the meridians and blood vessels in our body that we cleaned up after taking the Pulp Cleansing Pill, and I only figured it out after I woke up. ”

"I'm going... So much, so dark, and Tema so stinky! I can't stand it, I'll go take a shower first. ”

After listening to Cao Qi's explanation, Li Xiang calmed down, took off his clothes and pants to clean up the sheets, and ran to the bathroom.

Cao Qi smiled helplessly, threw his clothes, pants and sheets into the washing machine, covered the lid of the washing machine, pressed the on/off button, and returned to his bed to continue cultivating.

As soon as I thought about it, I heard Li Xiang's voice: "Screwdriver, it's not right! I just saw that the color of your clothes and pants doesn't seem to be as deep as mine! When you woke up, the level was lower than mine, how could it be that the impurities in your body were less than mine?"

"It's nothing, it only shows that my talent for cultivating physique qi and blood is better than yours, and I can already sense the existence of physique qi and blood in my body. ”

Cao Qi said calmly, he didn't want Li Xiang to know that he had already experienced a I Ching cleansing, otherwise he wouldn't be able to explain it clearly.

"Shenma, can you feel the body, qi and blood in your body!?"

"I'm going... This myelin-washing pill is so powerful!"

"No, I'll have to sense it later, you're all in front. ”

Li Xiang said excitedly, and sped up the speed of taking a bath.

After a while, Li Xiang came out of the bathroom in a hurry, found out his clothes and pants to change into, went to bed and sat up, and did not forget to say to Cao Qi: "Starter, don't disturb me before running in the morning!"

After saying that, he closed his eyes and sensed.

"Hmm. ”

Cao Qi also closed his eyes, and when Li Xiang was taking a bath, he had already figured out how to better familiarize himself with the operation of his body's qi and blood, so he began to cultivate spiritual energy now.

At five o'clock on Wednesday morning, the alarm clock rang to get up, Cao Qi slowly opened his eyes, moved his muscles and bones, and felt comfortable, his cultivation this night was equivalent to the previous two or three nights of cultivation.

Li Xiang was listless, with a sad face, he didn't feel the existence of the body's qi and blood all night.

Seeing that Cao Qi also woke up, he asked, "Screwdriver, how do you perceive the qi and blood in your body!?"

Cao Qi told him about his perception process, and Li Xiang was still frowning.

"Are you saying that the physique, qi and blood you perceive now are colorless energy ripples?"

"Well, that's it, oh! Don't worry! I can't feel that there is tomorrow today, why do you keep trying to compare with me! I'm just lucky. ”

"Let's go, wash up first, and then we'll have to run." ”

After Cao Qi comforted Li Xiang, he went to the bathroom to wash up first.

At 5:20 in the morning, the two came to the college playground and saw Lin Yun, who was already waiting here, doing body stretching exercises, and the two walked over.

Li Xiang also started to stretch his body without saying a word, and Cao Qi said hello to Lin Yun: "Miss Lin, it's so early!"

"Hmph, didn't you say it's five o'clock in the morning? Why are you here now?"

Lin Yun questioned Cao Qi a little angrily.

"Ahh

Cao Qi also looked innocent.

"You mean we met at the playground at five o'clock in the morning. ”

Li Xiang looked at Lin Yun's myelin-washing pill for the sake of it, and said this coldly.

"I'm going... You're elbowing out!"

Cao Qi was a little speechless, he usually didn't say a word, and at this time he came to dismantle his own platform.

"Hee-hee... Hurry up and get moving, and it's time to run. ”

Lin Yun smiled and grimaced at Cao Qi.

Cao Qi also began to do stretching exercises, and said to Lin Yun as he did it: "When you can run, you can control the use of psionic energy! ”

"If you can't keep up with us, you can use psionic energy, and if you can keep running on your own body, the exercise will be better. ”

"Okay, got it, don't talk about it, like an old mother. ”

Lin Yun was a little impatient, she wanted to try, how could she increase her cultivation speed with just one run.

Ten minutes later, both Cao Qi and Li Xiang finished stretching.

The three of them slowly ran side by side, and in the first kilometer, Lin Yun could barely keep up with Cao Qi's speed without using psionic energy.

At the beginning of the second kilometer, Lin Yun's breathing was getting faster and faster, and he felt that his physical fitness had decreased a little faster, and his legs and feet were getting heavier and heavier.

Slowly, Cao Qi and them pulled away a little distance, but Lin Yun was still reluctant to use spiritual energy, so he gritted his teeth and followed behind Cao Qi.

After two kilometers, Lin Yun had to use psionic energy, at this time she already felt exhausted, and if she didn't use psionic energy, she wouldn't be able to run.

After using the spiritual energy, Lin Yun's speed increased, and soon she was only about two hundred meters away from Cao Qi and them, and she also felt that Cao Qi's speed was getting slower and slower.

Soon, when it was close to three kilometers, Lin Yun caught up with Cao Qi and them, and her spiritual energy was already very little, seeing that Cao Qi and them were also out of breath at this time, sweating like rain, they felt a little proud in their hearts.

Waiting for the three-kilometer run to finish, Cao Qi and the others were already exhausted, so they stopped, and Lin Yun also stopped.

"What's going on! You can't run? That's not how you behaved during the fitness test!"

Lin Yun was a little strange, why Cao Qi and Li Xiang were so tired after only running three kilometers today.

Cao Qi breathed a sigh of relief before he said to Lin Yun, "We haven't used psionic energy all along, what about you using psionic energy?"

"I didn't use psionic energy for the first two kilometers, and I used it when I couldn't hold on to the last kilometer. ”

"It turns out that if you use psionic energy when your physical energy drops to the point where it is about to be exhausted, your psionic energy will also be consumed rapidly, so I used psionic energy to run a kilometer and I felt that my psionic energy was about to run out. ”
