This kind of change is obviously out of Chen Hui's expectation. However, Chen Hui is the party. Jiuyan can laugh recklessly, but Chen Hui only feels that he can't laugh or cry.

At this time, Chen Hui's skin is as black as coke, so he can't see people.

Chen Hui didn't talk nonsense either. He quickly sat down with his knees crossed and began to absorb the aura of heaven and earth into his body to replenish the aura of Qi sea and elixir field in his body.

"No!" As soon as Chen Hui was running on Sunday, he opened his eyes, and his face looked sad and smiling again. It was just that there was more helpless bitter taste than before.

"What's the matter?" Jiuyan sees Chen Hui's appearance, hears Chen Hui's words, realizes that Chen Hui has really encountered a problem, and quickly goes to ask.

"I'm very slow to absorb the aura of heaven and earth into my body!" Chen Hui said with tears and laughter.

Only Chen Hui, Jiu Yan and Su Yin know the saying of heaven and earth aura.

Because this statement was made after they analyzed the different auras in Chen Hui's body at that time.

The so-called aura of heaven and earth refers to the aura stored in Chen Hui's Dantian sea of Qi. This aura is not divided into five elements, and is the same as the aura cultivated by Jiuyan and Suyin.

In order to distinguish them from the five elements aura, Chen Hui called them heaven and earth aura.

No need for Chen Hui to explain anything more, Jiuyan understood it in an instant, and after understanding it, Jiuyan laughed again!

There is no doubt that Chen Hui's speed of absorbing the aura of heaven and earth has become extremely slow, which is the result of his change at this time.

Chen Hui's change at this time is like black charcoal. In fact, it is because he radiates aura from the inside out to the four limbs of his body, and forces the dirty air from the inside out to discharge out of his body.

In other words, Chen Hui's dirty Qi has become substantiated. It's not sure what the actual substantiation is, but the result is that Chen Hui's skin turns black, like black charcoal. This change also leads to Chen Hui's slow absorption of heaven and earth's aura.

Jiuyan's understanding of this is just here.

But Chen Hui has a deeper understanding, because the world Chen Hui came from is based on the research results of Western Medicine on the structure of human body.

In Chen Hui's opinion, his situation at this time is actually similar to that when his pores are blocked, the dirty air in his body can't be discharged. At the same time, because his pores are blocked, he can't quickly absorb the aura of heaven and earth.

Of course, the so-called blocking is just a central description. To be more precise, it should be blocking.

If it is completely blocked, Chen Hui will not be able to absorb any aura of heaven and earth into his body.

A more vivid description is that the sewer is blocked. If it is completely blocked, it will not be able to go down at all. If it is not completely blocked, it will go down very slowly.

Chen Hui's situation at this time is actually like this.

"What about the Buqi pill? Do you have a tonic pill with you Jiuyan stopped laughing for a long time and said, "you don't have any way now, only Buqi pill works best!"

Jiuyan is telling the truth, but Chen Hui has only five kinds of Qi tonifying pills at this time, and the five kinds of Qi tonifying pills can't supplement the aura in Dantian Qi sea. They can only supplement the corresponding aura, and they can only be stored in the five zang organs. They can't be stored in Dantian Qi sea.

Fortunately, Chen Hui took the bronze tripod with him.

"I'm going to look for herbs!" Chen Hui says helplessly that no matter what time it is, he goes out of the ethnic community and looks for medicinal materials in the dense forest outside.

This matter, nine Yan is not helpful, because nine Yan is not proficient in medicinal materials.

Besides, Jiuyan also needs to practice. At this time, Su Yin has given Jiuyan the magic weapon of flying sword, and let her practice it quickly with the magic weapon of flying sword. Time is also precious to Jiuyan.

Chen Hui searched for some herbs in the middle of the night, and finally found some herbs. Then he directly used the bronze tripod to refine the Buqi pill in the dense forest.

There are only two Buqi pills in these herbs.

Chen Hui, regardless of whether it was enough or not, immediately took two Buqi pills.

After entering the body, Buqi pill immediately works. Chen Hui can clearly feel that the aura in Dantian Qihai is slowly improving.

However, the two invigorating pills did not fill Chen Hui's aura in his elixir.

Chen Hui estimated the aura that he used to run Dantian Qihai from the inside out, sighed, and got up to continue to look for medicinal materials.

Because after calculation, Chen Hui found that he was full of Qi and might still hope to be able to expel these dirty Qi. When he was not full of Qi and Qi, he had no hope at all.

While searching for medicinal materials, Chen Hui also tried to absorb the five elements aura into his body, and found that it was extremely smooth to absorb the five elements aura into his body.

However, the five elements aura can not supplement the aura of Dantian Qihai, but can only supplement the five elements aura of Dantian Qihai.

It's just like a one-way street. It's feasible to transport aura from Dantian Qihai to five zang organs, but it's impossible to transport aura directly from five zang organs to Dantian Qihai.

At the same time, Chen Hui is also thinking about another question in his mind. The five elements aura can't supplement the aura of heaven and earth defined by him, Jiuyan and Suyin. Does it mean that the aura of Dantian is higher?

In other words, is Reiki a way to supplement Reiki from higher level to lower level?

And it's totally impossible for the lower order to supplement the higher order?

This possibility exists, but Chen Hui is unable to determine at present.

Chen Hui had been looking for some herbs until the morning. After all, Buqi pill also needs to be composed of prescriptions. It needs many kinds of herbs, and the dosage is enough.

This time, Chen Hui used the bronze tripod to refine three Qi tonifying pills.

Five tonic pills are just right to fill Chen Hui's aura in his Dantian sea of Qi.

Chen Hui went back to the lake and said hello to Jiuyan. He immediately sat down with his knees crossed. Facing the morning sun, he began to send out the aura of the sea of elixir into his body in the same way as before, forcing the foul air out of his body.

Chen Hui's estimate is correct, but he has no estimate of time.

It's true that Chen Hui expelled the foul air from his body, but it took him a whole morning. By the time Chen Hui expelled the foul air from his body in this way, it was already noon.

At this time, Chen Hui's elixir was lost in the sea of Qi!

Different from the previous one, although successful this time, Chen Hui also felt a great sense of fatigue. When the foul air was discharged from the body, Chen Hui lay down by the lake, breathing heavily.

After a while, Chen Hui sat up and jumped directly into the lake, because the foul air discharged from the body was materialized. A sticky layer of black material covered Chen Hui's body and gave off an unpleasant smell.

Chen Hui jumped into the lake, of course, in order to clean up the essence of the foul air.

Soon, Chen Hui came out of the lake, turned fire into aura, and dried his clothes.

Then, Chen Hui sat with his knees crossed and began to absorb the aura of heaven and earth into his body, which was stored in the sea of Qi in Dantian.

After Zhou Tian's movement in Chen Hui's body, aura exists in the sea of Qi in Dantian.

However, Chen Hui can clearly feel that he is absorbing the aura of heaven and earth into his body much faster than before.

In a short time, Chen Hui's aura in his Dantian Qi sea was completely filled. This speed was even faster than that of taking Buqi pill to supplement aura, and the difference was not big.

You know, the speed of absorbing weather aura into the body is quite different from that of taking Buqi pill to supplement aura.

"It's very fast!" At this time, Jiuyan comes to Chen Hui and throws him a roast chicken.

This roast chicken is a pheasant. It's obvious that Jiuyan caught it. When Jiuyan saw that Chen Hui was practicing, he didn't come to disturb Chen Hui. Instead, he baked the pheasant in the ethnic community and brought it.

It's just that the meat of pheasant is not as delicious as that of Chen Hui's world, because this kind of pheasant has a huge amount of activity, and its meat is tight and hard to bite. It's more suitable for cooking than roasting!

Of course, Chen Hui won't say that. He took Jiuyan's roast chicken and took two mouthfuls of it. Then he put it in the lake and said, "I've changed a lot since I discharged the foul air!"
