After taking the gray cloth bag, Gu Yi followed the original path back to his residence and cautiously closed the door.

Glancing at the gray cloth bag in his arms, Gu Yi breathed a sigh of relief, the rules in the door are quite strict, once others know that they went to the back mountain without permission, then the matter will be big.

Back at the residence, Gu Yi poured himself a glass of water, rested for a while, and then slowly got up, took off the green clothes on his body, and took off only the white wrap, covering the important parts, revealing his body covered in scars, skinny, but it looked very healthy, without a trace of fat.

Stripped naked, Gu Yi moved his hands and feet, slowly opened the gray cloth bag, and the next moment, the surrounding space suddenly changed, and there was a wooden basin like a trick, which was filled with steaming hot water, and the water temperature was still hot when he touched it, it seemed that Gu Yi had prepared for it a long time.

Just as Gu Yi took out the wooden basin, a black shadow quietly approached the thatched house, and his dark eyes looked through the doors and windows, watching everything inside.

"Wanling ointment, Wuzhi Baihua ointment, snow lotus jade toad pill, lark fairy grass ......"

Gu Yizhen took out the herbs he had just bought from the shopkeeper Wang, and took out some rare medicinal materials from the gray cloth bag, and put them on the table one by one, still reciting words in his mouth.

"Ten Thousand Soul Ointment, stimulating the potential of the body, suitable for martial artists in the Qi Refining Realm. ”

"Bailing Fairy Grass has the effect of washing away impurities in the body, and also has the purpose of restoring aura, which is suitable for martial artists in the acquired realm, and it is the most important medicinal material for washing the myelin pill. ”

"Snow Lotus Jade Toad Pill is a third-order demon beast Snow Lotus Jade Toad Inner Dan, which contains a large amount of spiritual energy......"

“......”

As the medicinal materials were taken out one by one, Gu Yi had words in his mouth, constantly sorting out his memory, analyzing the medicinal properties of the medicinal materials, and seemed to know each medicinal material very well, with a wooden expression, which seemed to be all subconsciously spoken.

In the hidden place, those dark eyes were full of horror, obviously I couldn't imagine that a martial artist in the Qi Refining Realm was actually proficient in medicinal materials, and he also understood the unilateral side of the Purifying Pill, which was simply incredible.

What kind of person is this kid? Just looking at cultivation, he only has the Qi Refining Realm, how can he know a lot of knowledge that the martial artists of the Ning Yuan Realm don't know, is he from a proud family? But the old man remembered that this kid was not from a wealthy family.

Eyes narrowed, an old face suddenly appeared, it was the king's shopkeeper, the old guy frowned in surprise, and was very puzzled at this time.

In fact, as early as when Gu Yi came to buy medicinal herbs, he felt that something was wrong, full of doubts, and finally couldn't help but follow Gu Yi, wanting to see what the little guy was tossing, but he didn't expect to find this scene.

In the quiet room, Gu Yi didn't notice anything, after checking the herbs, he took out the lark fairy grass, his eyes narrowed slightly, and after a while, he exhaled lightly, and above his left palm, some white flames appeared......

As soon as the flames appeared, the temperature in the room rose a lot.

The shopkeeper of the king in the hidden place, staring at the white flame without blinking, his heart was a little shocked, his eyes showed a look of disbelief, although he knew that the white flame was caused by the release of aura, but only a martial artist in the Qi refining realm could release the aura and turn it into substance, which really made him unbelievable, even if it was the Ning Yuan Realm, he couldn't reach it, how did this kid do it?

According to common sense, if you don't reach the acquired realm, it is difficult to release the aura, unless......

With an indifferent face, the white flame in Gu Yi's hand fluttered slightly, devouring the lark fairy grass...... The flames were churning, and almost instantly, the lark fairy grass was burned into a small green liquid......

After grabbing the panacea ointment in his right hand again and throwing it directly in, the green liquid became significantly larger.

In turn, many medicinal materials were all refined by it, and the red-hot temperature kept calcining the impurities in them.

As the flame calcined, the green liquid gradually shrank and became smaller and smaller, until finally only about the size of a fingernail was left, and it was thrown directly into the wooden basin.

The water in the wooden basin gradually became turbid, and suddenly, the basin of clear water turned cyan.

The entire refining process lasted for an hour, and Gu Yi's face began to turn a little pale and he was very tired.

In the palm of his hand, the white flame gradually faded, and finally disappeared completely.

"It's finally done, let's cultivate here in the future! But the medicinal properties can only last for a month, that is to say, I have to buy these things for today once a month, and they are really expensive. Gu Yi's face was full of pain.

However, thinking of the effect of medicinal properties, Gu Yi felt that it was worth it, this method of using medicinal herbs to activate the potential of the body, he was not hearsay, these knowledge were naturally taught by the elders in the family, it was easy to prepare these herbs for the first time, but he was a fledgling, he actually discarded the wooden basin after only using it once, knowing that the medicinal properties lasted for a month, he almost slapped himself in the face.

Thinking that now that he needs to prepare all the herbs himself, he will need to struggle for several months, Gu Yi sighed.

With a lot of thoughts, he was stunned for a while, and then he ordered some medicinal materials, only the Snow Lotus Jade Toad Pill remained, and he picked up the Snow Lotus Jade Toad Pill in his right hand and held it in his mouth.

Finally, I looked at the green liquid in the wooden basin with satisfaction, and climbed into it with great difficulty.

When he entered the tub, his body was completely submerged in cyan liquid, and only his head was exposed.

The next moment, the cyan liquid seemed to have found a breakthrough point, like a dam with an open valve, constantly impacting Gu Yi's body, and there was a pure power constantly pouring into Gu Yi's body.

Feeling warm all over his body, Gu Yi was overjoyed, and hurriedly ran the Blood Spirit Technique, running it over and over again.

The moonlight shone through the cracks in the window, shining faintly on the neat room, dimly dim.

Gu Yi ** body, sitting cross-legged in the wooden basin, hands handed, just at the beginning of the exercise to continuously refine the energy contained in the Snow Lotus Jade Toad Pill, his body gradually turned a little red, and his breath was a little short.

After a few hours, his breath stabilized significantly, his chest was slightly slight, and his breath was very rhythmic, and his frowning brows slowly relaxed, looking refreshed.

The cyan water liquid in the wooden basin gradually emitted a faint air current, the air flow was slightly cyan, slowly climbing, and finally following Gu Yi's breathing, it was not bad at all into his body.

When the shopkeeper Wang saw this scene, he nodded in horror, knowing that most of this kid had completely absorbed the Snow Lotus Jade Toad Pill, and when he calculated the time, he only had more than two hours of time, and the speed was indeed much faster, and it seemed that this strange method had played a great role.

After another half an hour, Gu Yi opened his eyes slightly, his expression was extremely excited, he didn't expect that with the help of the cyan liquid, he actually insisted on running the Blood Spirit Technique for nearly three hours, and gradually had a feeling of breakthrough.

I believe that as long as he is given an opportunity, he will immediately break through the bottleneck.

In addition to being excited, Gu Yi didn't think much about it, and quickly closed his eyes again and began to focus on cultivation.

Shopkeeper Wang saw Gu Yi open his eyes excitedly, as if he was thinking about something, and then closed his eyes and cultivated, knowing that it was meaningless to lurk any longer, and then flashed silently, and left the thatched house a hundred meters in a breath.

Stroking his beard, the shopkeeper Wang is still very excited, at least he knows this method, he can try to use it himself in the future, as for handing it over to the door master, then he will never do it, it is best to keep good things for himself.

Less than half an hour after the shopkeeper left the king, a bloody light suddenly flashed in the thatched house, illuminating the entire simple room, and suddenly, the aura of heaven and earth had a strange change, but it was only for an instant, and then it returned to the same as before.

However, Gu Yi opened his eyes, stretched out his arms, and looked at the black ring on his right hand in horror.

Just now, he felt that he seemed to have a slight connection with the Black Ring.
