After killing the Earth Desert Python, Lu Chen didn't have to stay, and immediately rushed towards its lair.

Located in the heart of this mountain, when you first enter it, you find it cold and wet.

And in this nest, there are still a lot of white bones, most of them are human bones, and I don't know how many unlucky guys are in this place, who have been used as rations by this wild python.

Lu Chen and the others frowned and walked through these mountains of white bones, and then finally stopped at the end of the cave.

At the end of this place, there is a red land of rocks, and among these rocks, there is a pool about five meters wide.

This pool is filled with red blood, and from time to time some blood bubbles will rise in the blood pool, and when the blood bubbles burst open, there is a rich energy in them, and it immediately spreads.

"This is the blood pool of the Earth Desert Python?" Seeing this red blood pool that makes the scalp tingle, Hua Butterfly couldn't help but ask.

"Judging from this breath, this is the right one. Lu Chen nodded slightly, he could clearly sense that the aura in this blood pool was the same as that of the Earth Wild Python.

He then turned his head slightly, and said to the flower butterfly again, "I may need to spend some time here, but I need to trouble you to help me control the wind at the edge of the hole, is it all right?"

Flower Butterfly nodded, her gaze fell on the pool of red blood, and then a trace of worry appeared on her face and said, "This ...... Nothing will happen, right?"

Lu Chen smiled slightly and said, "Don't worry about me, although the energy in this is violent, he can bear it." ”

Seeing Lu Chen's insistence, Hua Butterfly didn't want to say anything, and then she instructed and said, "Since that's the case, then you have to be more careful, I will definitely not let the monsters outside disturb you." ”

"Don't be too far away from me!" Before Hua Butterfly turned to leave, Lu Chen immediately said to her.

Hearing this, Hua Butterfly couldn't help but feel warm in her heart, and then paused slightly, then turned around and walked towards the outside of the cave.

Although the strength of the flower butterfly was strong, Lu Chen did not dare to guarantee that outside the cave entrance, there would be some powerful monsters rushing in.

At least when the flower butterfly is close to him, Lu Chen can also take care of her safety.

Seeing the flower butterfly turn around and go out, Lu Chen looked at the blood pool in front of him with a somewhat solemn face, the energy in it was much more violent and rich than he imagined.

The blood pool of the Earth Wild Python is of great help to the refining of its own body, and at this moment, its own strength is at the peak of the lower grade of the ground level.

Lu Chen also wanted to take this opportunity to be able to get the tempering of this blood pool, so that the physical body could be upgraded to a higher level.

At least when sprinting to the middle grade, having such a solid foundation undoubtedly increases a few confidences.

Lu Chen stood on the edge of the blood pool and groaned for a moment, and then he no longer hesitated too much.

The power of merit in the body quietly rose at this time, and finally wrapped around the surface of the body, and then Lu Chen's body fell into the blood pool with a pop.

"Snort!"

As Lu Chen's body fell into the blood pool, the originally quiet Earth Barren Python Blood Pool suddenly boiled when it came into contact with the power of merit.

Countless blood bubbles continued to rise, and violent energy roared wildly in the blood pool.

This violent power faintly erupted with a strange sound like thunder, echoing in this cave.

These violent forces were like countless poisonous snakes, overwhelmingly hitting Lu Chen's body.

In the energy in it, I don't know what kind of thing is fused, Lu Chen can feel that the energy in it has an extremely strong corrosive force.

As soon as these violent energies touched Lu Chen's skin, they immediately burst out bursts of white smoke and rose up.

Even with the protection of the power of merit, Lu Chen could feel a faint tingling pain in his skin.

"Hiss......"

Under this stinging pain, Lu Chen couldn't help but gasp, and then his mind moved, and the power of merit in his body burst out again, enveloping his whole body tightly again.

As soon as the power of merit appeared, those surging violent energies suddenly erupted into a sneering sound, and then those corrosive energies gradually merged with the power of merit, transforming into a warm power and integrating into Lu Chen's body.

The kind of energy that he actually felt became a little cool, and Lu Chen began to breathe a sigh of relief.

After the fusion of the power of merit, those energies that were harmful and corrosive to Lu Chen were all skillfully separated by the merit pool.

The rest of the energies that were beneficial to Lu Chen were all injected into his body after being fused and refined.

With this stream of warm and cool energy pouring into his body, Lu Chen could clearly feel that this energy was constantly swimming in the flesh and blood veins and bones of his body.

Every time he obtained the tempering of these energies, Lu Chen would instantly feel that the tenacity of his body seemed to start becoming stronger and stronger at a slow speed.

In this process of continuous tempering, Lu Chen enjoyed it very much.

This feeling of cultivation is indeed very fulfilling.

Sensing the subtle changes in his body, Lu Chen's heart couldn't help but surge with joy.

This progress may seem very slow, but it goes on like this. I'm afraid that I can really use this energy to lay a more solid foundation for the strength of the peak of the lower grade of the earth.

This is also with the help of the power of merit to get along, if it is an ordinary cultivator, just soak in the blood pool of this wild python like this.

Not to mention refining the energy in it, being able to hold on to this blood pool for five minutes is already extremely good.

Within the blood pool, as more and more energy was injected into Lu Chen's body, he closed his eyes tightly, gradually immersed in this kind of cultivation, and he didn't know how long time had passed......

And in Lu Chen's quiet cultivation, nearly three days passed in the blink of an eye.

In the past three days, the flower butterfly has stayed in this cave, and there are no particularly fierce beasts around.

This is also because those demonic beasts have a sense of territory, and this area belongs to the territory of the desolate python, and some other fierce beasts naturally dare not approach easily.

So much so that in the past three days, it has always maintained a safe state.

In the depths of the cave, in the current blood pool, the water in the pool has been reduced by nearly two-thirds, and even the red color has faded a lot.

Lu Chen, who was in the center of the blood pool, the skin on his face was much more rosy than three days ago, and under his skin, it was as if there was endless blood flowing.

Lu Chen, who was refining the blood pool, was still tightly closing his eyes at the moment, his body was not moving, and he was sitting cross-legged like a sculpture.
