In the spacious and bright cave, Xiao Yan looked at a large wooden basin placed in front of him, the wooden basin was filled with crystal clear water, and on the side of the wooden basin, there was a simple wooden frame, which was full of all kinds of medicinal materials.

"Give me the geocentric milk. After checking whether the required medicinal materials were complete, Yao Lao stretched out his hand to Xiao Yan and said martial arts.

Hearing this, Xiao Yan hurriedly put the thing into Yao Lao's hand according to his words, and the latter held the jade bottle full of "Earth's Heart Stimulation Milk" and weighed it slightly. Immediately ripped off the cap of the bottle, and suddenly a faint emerald smoke wafted out, and finally condensed at the mouth of the bottle, and it did not disperse for a long time.

Yao Lao took a deep breath of this smoke, and indeed felt a faint warm current flowing through his soul, and couldn't help but smile and praise: "It is worthy of being a spiritual creature 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, he asked the veteran to tilt the jade bottle slightly, and carefully poured ten drops of liquid like jade beads into the wooden basin. After the ten drops of jade liquid left the bottle, the liquid in the bottle was immediately reduced by nearly a quarter.

And with the ten drops of "the dripping of the earth's core quenching milk", I saw that the clear water in the wooden basin immediately transformed into a rich jade color at a speed visible to the naked eye, and a faint smoke gradually seeped out above the water surface. It has endured for a long time, and it looks extremely strange and martial arts.

Curiously looking at the changes in the water in the wooden basin. Xiao Yan scratched his head and said in astonishment, "Could it be that this time I am also cultivating here?"

"En" Yao Lao looked at the change in the color of the water with full attention, and said casually: "The energy of the Earth's Heart Quenching Body Milk 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 also be combined with other drugs to have the effect of washing the marrow and refining the bones, otherwise if you force it, let alone wash the marrow, your little life will be washed away directly. ”

Xiao Yan sneered, his body bones are not so weak, right?" Give me the "Incense Candle Grass", ignoring Xiao Yan's secret muttering, Yao Lao lightly instructed Dao Wu to move after observing the color concentration of the water.

Hearing this, Xiao Yan quickly stretched out his palm on the wooden frame, picked up a small red grass shaped like an incense candle from it, and then handed it to Yao Lao Wu Qiankun.

Holding this "incense candle grass", the old medicine man shook his palm, and a white flame was formed in the palm of his hand, and the white flame rose up, like a ball of ice flames.

Casually threw the former into the flames, and in just a moment, the incense candle grass quickly withered, and finally turned into a drop of red liquid in the scorching heat of Gu Ling's cold fire.

After refining the red liquid on the ground several times with the cold fire of the bone spirit, Yao Lao flicked his fingers, and the red liquid fell into the wooden basin.

As this drop of red liquid fell, the water surface that was originally like an emerald color also quietly turned a little red.

"Qinglian Fruit" Yao Lao spoke lightly again, and Xiao Yan hurriedly found this fruit medicinal material from the wooden frame.

After a few minutes of refining, the green lotus fruit also turned into a drop of cyan liquid and fell into the wooden basin, and there was also a faint touch of cyan martial arts in the water.

"Snake deflowering". Buddha Flame Root."

The medicinal herbs with different names continued to spit out from the medicine elder's mouth, and with the spit out of his voice, the medicinal herbs on the wooden frame also decreased rapidly, and after an hour, dozens of medicinal herbs were thrown into the wooden basin as a liquid of different colors.

After refining the last medicinal material, Yao Lao 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 Xiao 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." ”

Xiao Yan looked at the multicolored liquid that had been gathered by integrating the essence of dozens of medicinal herbs with a surprised face. I couldn't help but admire Yao Lao's miraculous method of condensing medicinal materials, but this kind of 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 be able to achieve martial arts.

"Be careful after entering, although the 'Earth Heart Quenching Body Milk' has become much more docile after being neutralized by the cultivation of 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 Lao clapped his hands and said with a smile.

Xiao Yan nodded, quickly took off the clothes on his body, and then turned over and jumped into the wooden basin with some impatience.

As his body invaded the colorful water, Xiao Yan's body suddenly shivered, and the temperature of the water was frighteningly low. If you don't use Dou Qi to protect your body, even your skin will feel a piercing pain.

"Don't use your fighting energy to wrap your body, that will prevent the medicinal power from entering your body, the cold of this water is because of the cold fire of my bone spirit, and it will not do you any harm. Just when Xiao Yan couldn't help but want to use his fighting spirit to fight the cold, Yao Lao's voice suddenly sounded martial arts.

Hearing this, Xiao 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 state of cultivation, and the energy filled in the water began to drill into his body without helping, making Xiao Yan feel itchy all over his body, as if there were ants crawling on his body.

Shaking his head fiercely, Xiao Yan suppressed the discomfort in his body, he has suffered a lot over the years, so these numb feelings can't make much of an obstacle to him, sitting cross-legged in the wooden basin, his hands are knotted with cultivation seals, his eyes are gradually closed, his breathing quietly becomes balanced and long, after half a sound, the tingling feeling on his body slowly fades, and Xiao Yan has also entered the state of cultivation.

The medicine elder beside the wooden basin looked at Xiao Yan who had entered the cultivation state, 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 impacted by that huge energy to operate, and in the end it will end up with more than worth the loss, although there are some risks, but the path of cultivation, without risk and fearlessness, how can you go far?"

As Xiao Yan entered the state of cultivation, the spotted water surface in the wooden basin suddenly hurt small 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 Xiao Yan extremely cold and martial arts.

At the moment when the blisters surged, Xiao Yan's body trembled violently, and he could feel that at this moment, countless streams of pure energy in the water liquid, as if they were being pulled by some kind of traction, were forced to pour into the body along the slightly open pores of the whole body!

Because the influx of energy was too huge, Xiao Yan even noticed 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, and after getting the leech, there was nowhere to drill the pure energy. It was actually scurrying under Xiao Yan's skin, and as they moved, the skin on Xiao Yan's body also puffed up traces of scurrying around, as if there were small snakes hidden under the skin. It looks quite terrifying.

、

Xiao Yan naturally couldn't detect the hideous horror on the outside, and now he could only use his mind with all his strength, paying attention to any movement in his body at any time.

Those colorful speckled energy that poured into his body did not listen to any command from Xiao Yan, but rushed directly to all bones in his body with extreme purpose. And all the bones that they bumped into would change into multicolored colors in an instant, and under these colorful colors, Xiao Yan could vaguely feel that something had invaded the bones, and it was also mixed with the bone marrow.

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

In less than ten minutes, the bones in Xiao Yan's body were almost completely shrouded in the speckled color, and at a glance, there were colorful colors everywhere, which was quite strange and martial arts.

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

Clenched his teeth, Xiao Yan's body in the wooden basin couldn't help trembling slightly, and a strange ruddy appearance appeared 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.

Yao Lao, who was standing outside the wooden basin, looked at Xiao Yan's actions, and the corners of his eyes couldn't help jumping, and then he sighed lightly, and said in a low voice: "Little guy, you have to stay up;
