In fact, judging from the surface of this stone, except for the crystal clear color, Yueting did not feel anything abnormal. So, she squinted, "What? Is this stone weird?"

"I'll try!"

After Shen Feng finished speaking, he didn't explain, he sat down cross-legged directly, held the stone with one hand, and began to mobilize spiritual power to circulate in the meridians.

As a result, after this cycle was carried out five or six times, Shen Feng did not notice anything unusual except that the stone became warm.

However, Shen Feng did not stop there, he still closed his eyes and accelerated his speed again, allowing the spiritual power in his body to contact the stone through his palm.

It wasn't until about thirty cycles later that Shen Feng was shocked in his heart. At this time, the stone in his hand began to slowly seep down his pores and into his body like the burning magma on the ground.

It's just that what's even more strange than this is that judging from the color, the flame flowing from this stone that Shen Feng has always identified as containing the power of the fire spirit, in addition to the scorching heat, is actually mixed with a piercing chill.

At the moment when the flame came into contact with the spiritual power in the body, the power of the fire spirit and the water spirit in the body, which was originally small, actually pounced like crazy. The moment he came into contact with the flames, he immediately fused with them, and then like a pioneer who opened the way, he rushed through the meridians with this indescribable power of ice and fire.

If it is a time for great health care in a massage room, the taste of ice and fire will always make people yearn for it. But now when these two completely unblended feelings are running around in the meridians in the body, that feeling is a bit miserable.

At this time, Shen Feng's meridians were like a channel that had been poured with gasoline and ignited, and the scorching pain seemed to burn people to ashes, but this pain had just been tasted, and what followed was a cold qi that was enough to directly turn people into popsicles, filling the entire meridians.

Shen Feng could even feel the sizzling sound from the wounding of the meridians.

He wanted to stop and rest, but he soon found that as long as the speed of his circulation was reduced slightly, the entire meridian was either burned by the flames or frozen by the cold. Only when you keep running at high speed will you suffer less.

There was no way, Shen Feng had no choice but to grit his teeth and speed up again and again. After a stick of incense, even Shen Feng himself didn't know how many laps this cycle had taken before the original scene of ice and fire began to slowly show signs of blending with each other. At this time, the round stone that was originally in Shen Feng's hand was already empty except for some fine slag.

"Whew!"

A fine light flashed from his eyes, and Shen Feng opened his eyes and exhaled. It was found that the spiritual power in the body was completely in a red and white liquid state at this time, and even the two spiritual powers of water and fire had exceeded the appearance of the seventh layer of qi training. If you have another one, you are sure that you will reach the level of the previous foundation building period.

"How?"

Yue Ting looked at Shen Feng curiously, although she could feel that Shen Feng at this time was stronger than before, but as for how much stronger, it was not something she said she could see through.

"Yes, let's see if there's anything like this around!"

Shen Feng smiled, and then immediately began to look for a similar cobblestone.

After a period of tossing, the two of them really found four in the stone wall, one of which was even the size of a fist.

In the next two hours, Shen Feng had been in a state of absorbing the spiritual power of water and fire. Knowing that after all the four cobblestones were absorbed, Shen Feng's two spiritual power attributes, water and fire, were already about to reach the realm of foundation building.

With this realm, it brought great convenience to Shen Feng to find spirit stones. When he first came in, Shen Feng couldn't touch the flames flowing on the ground at all. But now, as long as Shen Feng wants, he can press the ground with his hand at any time to absorb it. It's just that after absorbing the cobblestone, the little aura absorbed from the ground has become insignificant.

"You don't absorb it?"

Yue Ting asked,

Shen Feng shook his head, "Don't suck it, if you suck it like this, it's too much of a waste of time." Let's see how we get out first!"

The two came to the place where they first fell and searched for a long time, but there was still no gain. This made Yueting a little anxious, "We won't be trapped here, will we?"

"You get out of the way, I'll try!"

After finishing speaking, Shen Feng held his breath, then raised his palms and pushed towards the entrance that came in.

"Boom"

A fire dragon then rose from Shen Feng's palms, and rushed towards the stone wall in front of him with teeth and claws.

"Squeak ......"

The flames, with their suffocating heat, attacked the stone wall as they entered. The whole cave is like a hot oven.

As time passed, the rocks on the stone walls began to slowly melt and slowly flow downward.

"Why can't it work?" Shen Feng frowned, and after resting for a few seconds, a bucket-thick column of water appeared between his hands again, and with a thick chill, it suddenly smashed towards the slowly melting stone wall.

"......"

A foul white smoke then rose on the stone wall, and then due to the heat, expansion and contraction of the stone wall, accompanied by a slight click, the stone wall began with a crack that appeared at the beginning, and gradually spread to all sides.

"Get out of the way!"

Seeing that his method worked, Shen Feng grabbed Yue Ting and quickly retreated.

Before he could take two steps back, he heard a bang, and the stone wall that blocked the two of them collapsed. Under the light of these flames, the originally dark path outside also became bright at this time.

Shen Feng pulled Yue Ting, swept through the air, and then stood firmly on the path outside.

Walking along the path, after turning a few corners, Yueting finally stopped and came to a fork in the road in front of her.

"Right here!"

Shen Feng looked at it for a long time, and there was nothing unusual except that he found that it was just a crooked fork.

"Follow me!"

Yueting said as she walked into the fork in the road and came to a one-man tall stone.

"In order to hide people's eyes, this place is blocked with stones. As long as we push this stone away, it's inside!"

Pushing the stone was completely effortless for Shen Feng, I saw him stretch out his right hand, and in front of this stone that was more than one person high, he pulled it very casually, and the stone was pushed to the side.

Behind the stone, there was another swarthy hole, and Shen Feng tried to look inside, but still found nothing.

"Is this the spiritual vein you said?" Shen Feng questioned with a frown.

"Naturally, it can't be so simple!"

This time, Yue Ting took the lead in getting in, and after a while of searching, she slammed it on a protruding stone.

"Click!"

With a soft sound, a small door opened on the stone wall not far away. The moment it was opened, a faint halo shone through.

"We can't stay here any longer, and when we get in, we'll have to close the stone door from the inside!"

Yue Ting beckoned Shen Feng and walked towards the stone cave that emitted a halo.

Just as Yue Ting casually closed the stone door, Shen Feng used the halo to check the surrounding situation.

This stone cave, like the stone cave outside, stretches inward in a zigzag way. The only difference is that the surrounding stone walls are inlaid with all kinds of jade-like spirit stones. Although most of them are only the size of soybeans, a few egg-sized spirit stones occasionally appear.

"Oh my God!"

Looking at the stone cave in front of him like a stone cave with colored lanterns, shining in front of his eyes, Shen Feng was a little speechless with excitement, and it was not until Yue Ting closed the door of the stone cave that he came to his senses.

"So many spirit stones!"

"I really didn't expect there to be so many spirit stones here!"

Like fools, the two of them shuttled back and forth in the cave, touching the spirit stones that were exposed and emitting halos with their hands from time to time.

The passage inlaid with spirit stones is not long, and it is only four or five meters in total. Further down is the kind of ordinary black stone cave. Although for people like Yue Ting and Shen Feng, who have never seen so many spirit stones, they are extremely shocking. But after all, it's just like Yueting's father said, a little bit of the spirit mine.

After calming down his excited emotions, Shen Feng directly mobilized his spiritual power, pulled out a spirit stone with a stone from the stone wall, and then sat cross-legged on the ground with his eyes closed and began to absorb it.

This spirit stone was different from the red spirit stone just now, and after Shen Feng absorbed it, he discovered this problem. The one just now is the twin spirits of water and fire, and the one in front of you has no attributes at all. It's like the O type of panda blood in the blood, which can match any blood. In contrast, this kind of attributeless spiritual power is definitely an unattainable treasure for cultivators.

Soon, there was nothing left in his hand except for some stone residues. Shen Feng didn't open his eyes, he directly stretched out his hand and waved it on the stone wall, and three or four spirit stones the size of broad beans were held in the palm of his hand.

Looking at the gradually growing spiritual power in his body, Shen Feng was already completely in a state of crazy absorption.

On the other side, it took Yue Ting a long time to pull out a spirit stone the size of a soybean from the stone wall. I saw her follow Shen Feng's example and sit cross-legged on the ground. Slowly absorbing the spiritual power above.

Unlike Shen Feng's whale sucking, what Yue Ting absorbed was only filaments that were almost invisible to the naked eye. However, from the satisfied expression on her face, it could be seen that she was also very satisfied with the speed of her absorption.

As time passed, there were fewer and fewer bare spirit stones on the stone walls. And the aura of the two of them after absorbing the spiritual power became long.

Two hours later, there was no trace of the spirit stone on the stone wall. The whole cave became black.

Although there were no spirit stones that could continue to be absorbed, Shen Feng sighed slightly, and began to compress and fuse the spiritual power in his body again and again. It wasn't until the spiritual power that was originally like mist finally turned into a ping-pong ball, and the colorful spirit beads were suspended in the dantian, that Shen Feng suddenly opened his eyes.
