Lu Yun closed his eyes and let himself feel more carefully.

This is a breath of qi, the same as the elixir in the Holy Medicine Hall.

Lu Yun was surprised, could it be that this is the revived aura between heaven and earth, the secret of the elixir?

He wanted to feel these aura, but found that these qi were like spirits in heaven and earth, and no matter how he tried to grasp them, he couldn't grasp them.

Just when he was in a hurry, a rhythm suddenly appeared in his mind, and he naturally began to breathe according to this rhythm.

In an instant, the aura around him became clearer, and with his exhale and breath, it entered his body.

Lu Yun seemed to have discovered something interesting, and he breathed happily.

A quarter of an hour later, he suddenly felt very tired and fell asleep.

Early the next morning, Chen Lao got up to clean up and was shocked when he saw Lu Yun in a coma.

"Childe, Childe, what's wrong with you?"

Lu Yun slowly opened his eyes, but he felt refreshed, which made him very surprised, the aura had such an effect.

It's just that last night's breathing method was going on?

When did you learn these aura?

This method of breathing was as if it were engraved on his soul and let him go with the flow.

Being able to absorb the same aura as the breath of the elixir shows that this breathing method is very special and precious.

Lu Yun understood the truth that Huaibi was guilty, and it seemed that he would not be able to run the breathing method in front of people in the future.

He shook his head: "It's okay, I just couldn't sleep last night, I came to the yard to look at the moon, but I suddenly fell asleep again!"

Chen Lao sighed: "Childe still has to take care of his body, some things may be fate, and it is only right to be at peace with the situation."

Late the next night, Lu Yun secretly came to the courtyard again.

He closed his eyes and exhaled and inhaled according to the breathing method, and more aura was attracted by him and entered his body.

In the same quarter of an hour, he felt tired again and fell asleep.

This time, however, before dawn, he had woken up and returned to his room.

Next, Lu Yun seemed to forget about his troubles.

He practiced the knife throwing technique every day and used this breathing technique at night, while he also tried to capture the aura.

Half a month has passed, and I don't know if it's because of his diligent practice or because of the aura.

Lu Yun's flying knife technique has risen sharply, not only is it stronger, but even the accuracy has been greatly improved, and he can basically achieve no false shots.

The most exciting thing for him is that he successfully captured a trace of aura.

It's not a lot, but it's finally caught.

Now that the aura can be caught, a bold idea rises in Lu Yun's heart.

"Old Chen, Old Chen!"

"Childe calling me?" Old Chen walked out.

Lu Yun took out the rest of the silver: "Old Chen, you go to the medicine hall to help me buy some herbs."

Chen Lao thought that he was going to use herbs to strengthen his body: "What herbs do you want to buy?"

Lu Yun naturally didn't know what to buy.

"Whatever, pick some cheap, buy more, don't be willing to give up the silver!"

Chen Lao was full of doubts, but he still left with the silver, and soon brought back a pile of herbs.

"These are not very valuable herbs, I don't know what Childe is going to do?"

Lu Yun smiled mysteriously: "I want alchemy!"

Chen Lao was stunned and shook his head.

"Thousands of years ago, alchemy flourished, and there were Taoists who used mountains, rocks, plants and trees as raw materials to refine gold pills."

"Regardless of the efficacy for the time being, but they all have alchemy artifacts and alchemy fire, I'm afraid you can't do this."

Lu Yun nodded.

"What Elder Chen said makes sense, please help me buy a stove and iron pot again."

Chen Lao hesitated: "Son, there is not much money left, if we continue to spend it like this, we can't even afford to eat."

"Old Chen just go and buy it, if my idea is correct, we won't have to worry about money in the future!" Lu Yun muttered.

Old Chen sighed, he originally wanted to persuade Lu Yun to give up, but seeing that Lu Yun was very interested, he didn't say anything.

Soon, the stove and iron pot have been bought, and naturally you can't try it during the day, otherwise it will not be good to be discovered.

In the dead of night, Lu Yun took out a bunch of herbs and spread them on the ground, he wanted to verify his conjecture.

Looking at this pile of herbs, Lu Yun's heart felt strange again.

Although he didn't know the herbs, he felt they were all very familiar.

He had planned to pick a few at random, but instinctively picked out six herbs.

It seems that these six herbs together can exert a special effect.

The use of herbs is a matter for Lang Zhong, and Lu Yun naturally hasn't learned it, but he doesn't know why he feels this way.

Shaking his head, Lu Yun grinded the six herbs he picked out, put them in a pot and added water, lit the stove and began to boil.

As heated, the herbs gradually melt into the water, leaving only a bunch of impurities.

When the water was almost boiled, Lu Yun removed the impurities, and the remaining potion continued to boil until the bottom of the pot became a paste.

When the temperature cooled, Lu Yun took out the paste, kneaded it with his hands, and kneaded it into three walnut-sized balls.

At this point, his boiling medicine is basically over.

Looking at the black ball, Lu Yun was a little speechless, this appearance is too bad.

However, it didn't seem to affect his operation, and he continued to dry the three balls until they were completely firm.

Next was the most important step, Lu Yun sat down cross-legged and began to capture the aura, and forced the aura into the three round balls.

Everything went smoothly, with the integration of aura, the three balls produced a special charm, with the same breath as the elixir.

Lu Yun was overjoyed in his heart, and his conjecture was completely correct.

After doing all this, Lu Yun felt a wave of exhaustion.

Here it was again, and he only had time to curse in his heart, and then fell asleep.

Early the next morning, Chen Lao found Lu Yun asleep again.

However, when he saw the three black balls, Chen Lao was speechless.

"This is the elixir refined by Childe? How is it the same as a dried pill. ”

Lu Qiao'er picked up a round ball, looked at it carefully for a moment, and laughed out loud.

"Brother, is this the elixir you refined?"

Lu Yun shook his head: "You guys feel it carefully."

Chen Lao and Lu Qiao'er were stunned for a moment, and took the ball and carefully observed it for a long time.

"Isn't this just a pill? What's the difference? ”

Lu Yun was stunned: "You didn't feel it?"

The two wondered, "What do you feel?"

Lu Yun was also full of doubts: "You don't feel that there is something special in this?"

The two shook their heads, and Lu Yun was shocked in his heart, the two of them couldn't feel the aura.

Isn't Reiki felt by everyone?

It seems that my breathing method is more precious than I imagined, and I must be extremely careful in the future, and I must not reveal anything related to Reiki.

He shook his head: "If you don't feel it, forget it!"

"Old Chen, you disguise yourself, let's go out and see if we can sell these three pills?"

Lu Yun was going to test his guess.

He has no market, the best way is to sell to a marketable place, and the first choice is naturally a pharmacy.

Although the Holy Medicine Hall was the largest medicine hall in Luoyang, he didn't plan to choose, the goal was too obvious.

He set his sights on the Huairen Hall, which was second only to the Holy Medicine Hall.
