Seeing that the senior brothers and sisters had already entered the fourth layer, Xiao Cheng couldn't wait to step into it, but just when he was about to step on the spiritual barrier with one foot, he seemed to smell a strange smell, so he retracted his steps, looked at the medicine pool behind him that had become clear and transparent, and after a little contemplation, he turned around and walked towards the medicine pool again.

This time, Xiao Cheng is not to invade the medicine pool to enhance spiritual power, but he feels that this medicine pool seems to be a little strange, the medicine pool has been emitting a faint strange smell, but this strange smell is not the smell of medicinal materials, according to reason, for a medicine pool with such a high medicinal effect, even if it smells, it should be the smell of medicinal materials, the formation of the medicine pool is mostly to put some medicinal materials absorbed from the outside into it, so that the medicinal effect of the medicinal materials is completely integrated into the medicine pool, and then let people invade the medicine pool, absorb the medicinal effect in the medicine pool into the body, so as to achieve the effect of making the best use of things。

Therefore, for the medicine pool that has been soaked in many medicinal materials, even if it emits a smell, then most of the smell emitted should be the smell of medicinal materials, but Xiao Cheng, who has been buried in the medicinal materials since he was a child, did not smell a trace of the smell of medicinal materials in this medicine pool, instead, it was a strange special smell, this smell is very faint, if it is not for Xiao Cheng to sniff carefully, I am afraid that it really can't smell from the medicine pool.

Xiao Chengshang had already vaguely smelled this smell when he was still in the medicine pool, but he didn't dig into it at that time, and when he was about to bury himself in the fourth layer, he inadvertently smelled this smell again, and at this time, a voice in his heart was also telling him that this smell seemed strange, so he decided to find out.

Xiao Cheng walked to the middle of the medicine pool, held his breath, took a deep breath, and sniffed the medicine pool that had become transparent and had lost its medicinal effect again.

This time, Xiao Cheng also smelled that strange smell, this smell, with a little sour, and a little astringent, in short, this strange smell has nothing to do with the smell of medicinal herbs, and this smell is not very good.

So, where does this smell come from?

Xiao Cheng picked up a touch of pool water and sniffed it carefully, but found that the water was not the source of the strange smell, because the water was like clear water, and there was no smell at all.

Xiao Cheng stretched out his tongue and licked the potion, but when the tip of his tongue just touched the potion, he spat out the saliva, and the potion was too bitter.

Xiao Cheng spilled the potion into the pool again, and gently tapped his head with his right hand, as if he felt that his previous behavior was too stupid, the medicine pool was used for brewing, not for drinking, and in doing so, it was impossible to find the source of that strange smell.

But no matter how Xiao Cheng sniffed, he was sent to find the source of that strange smell, and he only knew that the strange smell came from the medicine pool.

Xiao Cheng pursed his lips tightly, but a stubbornness appeared on his little face, and he felt more and more that this medicine pool seemed to be not simple, if he could really find out the mystery, it might be extremely important to him.

Xiao Cheng squatted beside the medicine pool, his brows furrowed, his palms supporting his head, he fell into deep thought, and after a while, he was surprised to find that some green ripples seemed to begin to appear in the center of the medicine pool.

Then, the calm medicine pool was blistered from the middle under Xiao Cheng's surprised gaze.

Xiao Cheng's throat rolled, he took off his clothes, walked into the medicine pool again, and walked towards the middle of the medicine pool.

Walking to the center of the medicine pool, Xiao Cheng's eyes suddenly paused, and he sighed lightly, looking directly at the bottom of the water, because before, there seemed to be a little luster there flickering.

In this case, if it were placed in normal times, Xiao Cheng would definitely not care, but now, he is obsessed with this medicine pool, vowing to find out what is strange about this medicine pool.

Xiao Cheng's gaze locked on the place where the previous subtle luster flickered, and his eyes did not blink, and under his tight gaze, the flicker of the previous luster appeared again, and this time it was a little hurried, and then, a subtle light jetted upward, and under Xiao Cheng's gaze, the surface of the pool water, where the light points gushed, there was a circle of subtle ripples.

Xiao Cheng looked at the place where the subtle light poured into the medicine pool in a daze, and immediately swallowed a mouthful of saliva, and when the light gushed out of the water before, he vaguely saw that there seemed to be a drop of green liquid in it.

It seems that the secret is in the medicine pool, and it is under the water in the center of the medicine pool.

Xiao Cheng looked at the bottom of the water that sprayed green water droplets, and was surprised to find that there seemed to be a small stone lying there.

Immediately after, another subtle light shot upward, and this time, Xiao Cheng saw clearly, the green liquid was emitted by the small stone lying motionless in the pool.

And those green liquids are supposed to be the source of the medicinal effects in this medicine pool.

What kind of stone is this, it can emit such strange energy, Xiao Cheng wondered, he had never heard of anything other than medicinal herbs and pills that could emit medicinal effects, not to mention, there was not even the slightest smell of medicinal herbs here, but it had already emitted medicinal effects.

"Let's take it out and take a look!" Xiao Cheng muttered softly, and then he reached out and grabbed at the strange little rock under the water.
