At this time, outside the small world, in addition to Yue Gaoyuan, a few more people came, who were members of the Martial Alliance who came after receiving the news, and Wang Mingyu was also impressive!

It has been nearly an hour since he arrived here, Wang Mingyu anxiously looked at the location of Yue Gaoyuan's light gate, and while secretly praying for Zhou Yifeng's safe return, he kept moving, but his eyes never left the void.

Just when he was about to lose his patience, a ripple appeared in the place where his eyes were looking, and he was about to step forward with great joy, when a huge black shadow suddenly appeared, and then there was a muffled pop, and the corpse of a dog-like animal with a missing head fell to the ground!

Seeing Zhou Yifeng appearing, as well as the black dragon he was holding in his hand, Wang Mingyu's face was relaxed, and he hurriedly stepped forward and said:

"Xiaofeng, are you alright?"

Zhou Yifeng saw that Wang Mingyu was actually here, and after putting down the three black dragons, he said:

"I'm fine, Brother Wang, what's wrong with you?"

Wang Mingyu said:

"It's okay. I received a call from Yue Gaoyuan, knowing that you went in alone, so I hurriedly brought the people from the Wumeng here, but I couldn't enter, so I could only wait for you to come back. ”

Zhou Yifeng nodded, and told Wang Mingyu about the situation inside, and when he learned that the three corpses were cultivated before his death, Wang Mingyu's mouth opened wide in horror!

Then Zhou Yifeng took out the jade pendant and wanted to hand it to Wang Mingyu, but he refused, saying that he would let him keep it first, and if he could use it in the future, he would ask him for it.

After some conversation, Wang Mingyu commanded the wolf corpse to be loaded onto the helicopter, while Zhou Yifeng walked to the middle of the canyon to check the yellow stream.

At this time, Yue Gaoyuan walked over and said:

"Week. Instructor Zhou, thank you for catching the black dragon!"

When Zhou Yifeng heard Yue Gaoyuan call him Instructor Zhou, he knew that it must be Wang Mingyu who told him his identity, and he also understood that he said thank you because of the fact that Heilong killed his younger brother.

Zhou Yifeng waved his hand and said:

"Brother Yue is polite. ”

Yue Gaoyuan saw that Zhou Yifeng was very interested in this Huanglongquan, so he said:

"Instructor Zhou, I took a look just now, this stream entered the ground on the edge of the cliff at the end of the valley, and it seems that there is an underground river below. ”

Zhou Yifeng nodded, he had already checked with his divine sense just now, this stream did flow into a wide underground river, because the stream was small, after the confluence, he could no longer feel the aura. Now it seems that the only way to find out the cause is to start at the source.

At this time, Wang Mingyu had already loaded the wolf corpse into the helicopter and asked Zhou Yifeng if he wanted to go together, and Zhou Yifeng told him that he was going to practice here for a few days and let him go back first.

After everyone left by helicopter, Zhou Yifeng came to the place where the spring water flowed out, and his divine sense swept into the inside of the cliff, trying to find the head of the spring.

When Zhou Yifeng's divine consciousness penetrated into the cliff, he found that the original divine consciousness with a range of three thousand meters, after entering the rock, could only stretch out for less than a thousand meters!

But just this kilometer distance, he still made a discovery, about eight or nine hundred meters inward from this cliff, there was actually a cave that led to the other side! Zhou Yifeng stepped on the purple lightning and rose into the air, and carried out divine sense tracking along the cliff ridge, and finally found a place thousands of meters away from that cliff, a turbulent waterfall covered the entrance of a half-human-high cave!

Control the purple electricity to fall to the entrance of the cave, drum up the true yuan, and Zhou Yifeng rushed in. Upon entering, a damp smell hits the face, mixed with a faint smell of cement. Because this cave entrance is behind the waterfall, from time to time there is water blown in by the wind, forming a small stream in the cave, meandering forward, Zhou Yifeng secretly said, is this the reason for the formation of Huanglongquan?

After following the small stream all the way, the cave became higher and higher, and water droplets fell from time to time on its top, Zhou Yifeng looked up and saw that there were many, colorful bamboo shoot-like protrusions above, which were stalactites that were slowly formed!

After moving forward for a thousand meters again, a karst cave about 30 meters high about the size of a football field appeared in front of Zhou Yifeng, and thousands of stalactites hung down from above, some of which almost hung to the ground! And what made Zhou Yifeng's heart beat wildly was that in the middle of this karst cave, there was a giant stalactite with the thickness of a basin and milky white at the root! The bowl is about three inches high, the bowl is filled with a thick milky white liquid, emitting a burst of strange fragrance, take a deep breath, suddenly feel refreshed, and the soul seems to be cheering!

Occasionally, a drop falls and melts into the stream that flows below!

"Ten Thousand Year Stone Stalactites!"

Zhou Yifeng's face was red with excitement, his mind was blank, and his heart was almost jumping out, like a thunderous drum!

He finally understood why Huanglongquan had a trace of aura, it turned out to be because of the 10,000-year-old stone stalactites!

Seeing that a drop was about to fall into the stream below, Zhou Yifeng rushed to the scene, opened his mouth and sucked the drop of liquid out of the mouth of the bowl into his mouth! Suddenly, a majestic aura rushed into the meridians, transforming into a thick true element, and his cultivation actually rushed into the middle of the eighth layer of qi refining, almost reaching the peak of the middle stage! At the same time, the sea of knowledge was also cool, and the soul spring was even more cheerful with splashes, the small puddle at the spring seemed to have increased a little, and the space of sea knowledge seemed to expand outward by dozens of meters!

didn't have time to take a closer look at his own changes, Zhou Yifeng hurriedly took out a few jade bottles from the ring, put all the 10,000-year-old stone stalactites in the bowl into them, sealed them, and put them into the ring.

After collecting the elixir, Zhou Yifeng felt that there was still a strong fragrance, and couldn't help but wonder, could it be that there was still a 10,000-year-old stone stalactite?

"Bowl, bowl!"

Zhou Yifeng was shocked to find that this bowl was actually made of 10,000-year-old stone stalactites! No wonder he always felt that the strange fragrance was not far away, and it turned out to be in front of him!

The preconceived idea made him ignore this bowl, and he didn't think that there would be a bowl here.

Zhou Yifeng took out the purple electricity, cut off the entire bowl along the bottom of the bowl, put it in the ring first, and planned to make a relatively large jade box after going out and then put it in.

Then, he took out a jade bottle from the ring and placed it on the tip of the 10,000-year-old stalactite, ready to catch the next drop of the elixir.

But after waiting for a long time, I didn't see a drop falling, I looked up, and saw that the tip of the milky white stalactite had only a thin film of water, which was going to drip down, and I don't know how long I would have to wait!

Zhou Yifeng ignored it for the time being, sat cross-legged, and checked his knowledge. After entering the sea of knowledge, Zhou Yifeng found that the space of the sea of knowledge had increased from the original radius of 100 meters to a radius of 150 meters, and the splash of water spewing out of the soul spring had also become much larger, and the small Wang Qingquan seemed to be slowly expanding outward!

Looking at the changes in Zhihai, Zhou Yifeng was even more excited, the 10,000-year-old stone stalactites are really extraordinary, one drop can cause such a big change! You know, since he opened up Zhihai, no matter how much his cultivation increases, Zhihai has not changed much!

Thinking of the three and a half bottles of 10,000-year-old stone stalactites in his ring, as well as the big bowl, Zhou Yifeng's heart was hot! Feng Ziya had told him that the earlier the sea of knowledge was opened, the larger the space, the better the qualifications he would prove, and the faster the speed of cultivation! Feng Ziya had never seen the sea of knowledge opened up with the help of external forces in the middle stage of qi refining like him, but he knew that even if the sea of knowledge opened up when he was building the foundation, it was not as big as Zhou Yifeng's sea of knowledge, not to mention that a soul spring had formed in his sea of knowledge! It was even more unheard of in the cultivation world!
