In the spacious and bright cave, Ye Yan looked at a large wooden basin placed in front of him, the wooden basin was filled with crystal clear water, on the side of the wooden basin, there was a simple wooden frame, which was full of all kinds of medicinal materials, and there seemed to be dozens of kinds of forests, in order to find these medicinal materials, it took Ye Yan nearly three days.

"Give me the Meteorite True Liquid. After checking whether the required medicinal materials were complete, Yao Yu stretched out his hand to Ye Yan and said.

Hearing this, Ye Yan hurriedly put the thing into Yao Yu's hand according to his words, the latter held the jade bottle full of Qiang Hongwen, weighed it slightly, and then ripped off the cap of the bottle, and suddenly, a faint jade smoke wafted out, and finally condensed at the mouth of the bottle, which did not disperse for a long time.

Yao Yu took a deep breath of this mist, but felt a faint warm current flowing through his soul, and couldn't help but smile and praise: "It is worthy of being a spiritual object that condenses the power of the earth, it is so pure and rich, no wonder it has such a miraculous effect as washing the marrow and refining the bones." ”

After smiling and praising it, Yao Yu tilted the jade bottle slightly, and carefully poured ten drops of the jade-like liquid in the wooden basin, after these ten drops of jadeite liquid left the bottle, the liquid in the bottle was reduced by nearly a quarter.

And with the dripping of ten drops of meteorite true liquid, I saw that the clear water in the wooden basin was transformed into a rich jade color at a speed visible to the naked eye, and above the water surface, a faint mist gradually penetrated out, which lasted for a long time and looked extremely strange.

Looking curiously at the changes in the water in the wooden basin, Ye Yan shook his head and said in amazement: "Do you need to cultivate here?"

"Hmm. Yao Yu looked at the change in the color of the water with full attention, and said casually: "The energy of the Meteorite True Liquid is too huge, and it is impossible for you to take it directly with your current strength, so you can only take this way, and even so, it must be combined with other medicines to achieve the effect of washing the marrow and refining the bones, otherwise if you come forcibly, let alone wash the marrow, I am afraid that even your little life will be washed away directly." ”

Ye Yan smiled, his body bones are not so weak, right?

"Give me the rainbow grass. Ignoring Ye Yan's secret muttering, Yao Yu instructed lightly after observing the color concentration of the water.

Hearing this, Ye Yan quickly stretched out his palm on the wooden frame, picked up a small red grass from it, and then handed it to Yao Yu.

Holding this rainbow gong grass, Yao Yu's palm flickered, and a dark red flame took shape in his palm, and the dark red flame rose up.

Casually throwing the former into the flames, it only took a moment for the rainbow grass to wither rapidly, and finally turned into a drop of red liquid in the dark red scorching.

Ye Yan looked at the dark red flame in Yao Yu's hand and suddenly froze, he really didn't expect that there was actually a flame in Diandian, looking at the temperature of the flame, I am afraid it would not be lower than his Fire Ruin Empty!

"Dot, there are too many mysteries in you. Ye Yan smiled brightly and said.

"Hehe, there's a lot more you can't think of. Yao Yu smiled darkly.

After using the cold fire of the bone spirit to refine the red liquid on the ground several times, Yao Yu flicked his fingers, and the red liquid fell into the wooden basin.

As this drop of red liquid fell, the water surface, which was originally like an emerald, also quietly became a little darker red.

Medicinal herbs with different names continued to spit out from Yao Yu's mouth, and with the sound of spitting out, the medicinal herbs on the wooden frame also decreased rapidly, and an hour later, dozens of medicinal herbs were thrown into the wooden basin that had completely turned into liquids of different colors.

After refining the last medicinal material, Yao Yu also breathed a sigh of relief, his eyes looked at the wooden basin, and saw the water surface that had become colorful, then he nodded with satisfaction, and said to Ye Yan on the side: "Take off your clothes and enter it to cultivate, until the color of the water surface changes back to clear water again." ”

Ye Yan looked at the multicolored liquid that was fused with the essence of dozens of medicinal herbs with a surprised face, and couldn't help but admire Yao Yu's miraculous method of condensing medicinal materials, such a method has nothing to do with talent, it all requires the accumulation of experience and the understanding of the medicinal effects of various medicinal materials to achieve.

"Be careful after entering, although the Meteorite True Liquid has become much more docile after being neutralized by these medicinal materials, the energy contained in it has not decreased but increased, so when you are cultivating, you may have some pain, and you will benefit a lot from getting through it. Yao Yu clapped her hands and said with a smile.

Ye Yan nodded, quickly took off the clothes on his body, and then turned over and jumped into the tub a little impatiently.

As his body invaded the colorful water, Ye Yan's body suddenly shivered, the temperature of this water was frighteningly low, if he didn't use the source qi to protect his body, even his skin would feel a tingling pain.

"Don't use the source qi to wrap your body, that will hinder the medicinal power from entering the body, the cold of this water is because of my Dark Demon Emperor Fire, it will not do you any harm. Just when Ye Yan couldn't help but want to use the source qi to resist the cold qi, Yao Yu's voice suddenly sounded.

Hearing this, Ye Yan had no choice but to nod helplessly, his body was soaked in this colorful liquid, he could clearly feel the huge energy contained in it, which had not yet entered the cultivation state, and the energy filled in the water began to drill into his body uncontrollably, making Ye Yan feel itchy all over his body, as if there were ants crawling on his body.

Shaking his head fiercely, Ye Yan suppressed the discomfort in his body, he had suffered a lot over the years, so these sour and numb feelings could not make much of an obstacle to him, sitting cross-legged in the wooden basin, his hands formed a cultivation knot, his eyes were gradually closed, his breathing quietly became steady and long, after a while, the tingling feeling on his body slowly faded, and Ye Yan also entered the state of cultivation.

Next to the wooden basin, Yao Yu looked at Ye Yan who had entered the state of cultivation, nodded with a smile, and said softly: "Washing the marrow and refining the bones is of course a great benefit, but the hardships are not small, if you get through it, the road is flat, if you can't get through, not only will you fall short, but you can't say that your own meridians will also be damaged by the impact of that huge energy, and in the end you will end up with more than you can lose, although there are some risks, but the way of cultivation, without adventure and fearlessness, how can you go far?"

As Ye Yan entered the cultivation state, the colorful water surface in the wooden basin suddenly surged up with tiny blisters, and after a while, the blisters surged more and more violently, and it looked like he was in boiling water, although this boiling water still made Ye Yan extremely cold.

At the moment when the blisters surged, Ye Yan's body trembled violently, and he could feel that at this moment, countless streams of pure energy in the water liquid, as if under some kind of traction, were surging along the slightly open pores of the whole body, forcibly pouring into the body!

Because the influx of energy was so huge, Ye Yan even sensed that his skin was a little swollen and painful, however, these influxes of pure energy did not stagnate because of his feelings, but instead poured at a more ferocious speed.

In the end, the streams of pure energy, because there was nowhere to drill, actually scurried indiscriminately under Ye Yan's skin, and with their movements, the skin on Ye Yan's body also puffed up traces of scurrying around, that look, as if there were small snakes hidden under the skin, it looked quite terrifying.

The hideous and terrifying appearance Ye Yan naturally couldn't detect it, and now he could only use his mind with all his strength, paying attention to any movement in his body at any time.

The colorful energy that poured into the body did not listen to any command from Ye Yan, but rushed directly to all the bones in the body with great purpose, and all the bones that were bumped into by them would change into colorful colors in an instant, and under this colorful color, Ye Yan could vaguely feel that something had invaded the bones, and it was also mixed with the bone marrow.

Ye Yan didn't have the slightest way to stop these energy moves, so he didn't have the slightest way to stop them except to watch more and more bones in his body being rendered into colorful colors.

In less than ten minutes, the bones in Ye Yan's body were almost completely shrouded in that colorful color, and at a glance, there were colorful colors everywhere, which was quite weird.

Just when Ye Yan was a little puzzled by these energies, the tip of his heart trembled violently a few times, and he felt that the bones seemed to suddenly burn at this moment, and a burning sensation that penetrated deep into the bone marrow spread out rapidly, and finally spread to every corner of the body.

Clenched his teeth, Ye Yan's body sitting in the wooden basin couldn't help trembling slightly, and a strange ruddy flush also emerged on his skin, and his forehead was covered with cold sweat, and finally like a light rain, it slid down his face and fell into the wooden basin, he only now understood why Yao Yu said that there was some pain, but... Isn't this pain a bit too much?

Yao Yu, who was standing outside the wooden basin, saw Ye Yan's actions, and the corners of his eyes couldn't help jumping, and then sighed lightly, and said in a low voice: "Little fool, you have to stay up, if you succeed in purging the marrow, when you advance to the Holy Sect level in the future, it will save you a lot of trouble." ”
