Yinfeng Canyon is moving from north to south, winding for more than two thousand miles. The mysterious cave that Lao Hei mentioned is located in the depth of the southern area. The location of Suche at this moment is still more than five hundred miles away.

Now, Su Che has the fourth level of Qi training, and staying in Yinfeng Canyon for a long time is a prohibited behavior. However, the "Spiritual Covering Technique" that he just learned is just in handy, and he can easily imitate the spiritual power fluctuations of Qi training in a prisoner in the Immortal Prison. I believe that monks below the Foundation Establishment Stage will definitely not see any flaws.

It took more than an hour to arrive at the destination. The old black transformed into the form of the "Rat King" and sent out a spiritual summon. Soon, a black-haired rat king emerged from the crypt not far away. This area was the territory occupied by its tribe.

Under the leadership of this Rat King, Su Che and Lao Hei first crawled into a very inconspicuous small hole. After a distance just now, Su Che needed to kneel on the ground and crawl like a wild beast. Such a hole was as numerous as cows in the canyon, and generally speaking, it was not paid attention to by the disciples and casual cultivators of Tianxuan Sect who came here to experience.

After climbing for about twenty feet, the tunnel was much wider, Su Che was able to stand up and walk normally.

The trend of the tunnel is to tilt downwards, gradually penetrate deep into the ground, and after walking in a long time, it still looks bottomless.

"It's almost a thousand feet?"

Su Che calculated silently in his mind that this tunnel reminded him of the secret medicine garden of Xuanji Peak, which also penetrated more than a thousand feet deep into the abdomen of the mountain.

However, as he gradually deepened, Su Che realized that more than a thousand feet were really nothing. After walking several more than a thousand feet, the Black Rat King who was leading the way still ran quickly, without any intention of stopping.

"It's very deep!"

Lao Hei sensed Suche’s thoughts and replied with a smile: “This is nothing, it’s still deep in the back!”

Keep walking, still walking...

How deep it was to go deep underground? Su Che had long been unable to calculate it. He could only estimate it based on time. According to the current speed, he walked for two quarters of an hour and had been at least forty miles.

Finally, the Black-haired Rat King stopped, turned his head, and squeaked at the Rat King transformed from Lao Hei. Lao Hei relayed: "This Rat King said that if you go further, it dare not go further, because there is a very powerful red-tailed fox inside, which can be called the super nemesis of the Yinfeng Rat. Over the years, I have hunted countless Yinfeng Rats."

"Then let it go back and let's explore it on our own." It was just a red-tailed fox, Suche didn't care too much about it.

Lao Hei could sense Su Che's thoughts and reminded with a smile: "Master, this red-tailed fox is not ordinary. Think about it, the Rat King is already at the third level of Qi training. Its entire tribe has no choice but to use this red-tailed fox. Then, the strength of this fox..."

"Oh?" Su Che asked in confusion: "Didn't it mean that there are no intermediate monsters in Yinfeng Canyon? How could that red-tailed fox be so powerful?"

"This is the most interesting part of the cave here." Lao Hei replied: "There is a monster that surpasses the third level of Qi training, and even the Tianxuan Sect knows nothing about it."

"Okay, I've been here, I'll definitely find out what's going on."

Suche has developed a very high desire to explore for this kind of mysterious thing, because exploring such things can often bring considerable gains. In the world of cultivation, this is called a person's "blessings".

Next, the Black Rat King chirped twice and ran away along the original path; the image of the Rat King transformed by the old black also returned to the Immortal Prison, which turned out to Suche, who continued to move into the depths of the cave alone.

There was no light in the cave, and humans' naked eyes were completely invisible. However, Suche had long adapted to the advancement with Lao Hei's detection ability, and could fly with confidence and boldness with his eyes closed.

Still tilted downwards, twisting and turns, and after walking for a long time, Su Che suddenly stopped his pace.

Because Suche could see with his naked eyes that a small red dot appeared in front of the tunnel, and he obviously felt a heat current coming towards him, and the temperature suddenly rose countless times, as if a person accidentally fell into the boiling hot water pool.

"The temperature was still normal just now, how could it increase so much all of a sudden?"

With suspicion in mind, Suche took more than ten steps back, and suddenly, the heat flow coming towards him disappeared, and the surrounding temperature turned into a cool and cool again.

What's going on?

Suche tried several times before he was sure that there was an invisible barrier at this location that was invisible and invisible, like a transparent diaphragm, blocking the heat flow in front of him. Only by crossing this diaphragm can he feel the huge change in temperature.

"A man-made barrier or a natural barrier? How can such a thing exist underground?" Su Che silently conjectured.

"I don't know." Lao Hei had no idea and could only remind him: "This situation must be unusual. Master, it's still time for you to retreat now."

For Lao Hei, all the information he obtained cannot be concealed from the owner. Even if he thinks this matter is dangerous, he should tell the owner truthfully. As for how to make a choice, he must rely on the owner to make a decision. At most, he can only make a suggestion.

"No!" Su Che's decision was very decisive: "Since you embarked on the path of cultivation, you must have the courage to explore the unknown, otherwise you will miss countless good fortunes. Besides, if you don't move forward, how can we determine whether it is a blessing or a disaster that is waiting for the front?"

"Okay, I support any decisions made by the master." Lao Heipiao Astronomy Network said: "According to my estimate, the location here is nearly ten miles away from the surface, and the heat flow ahead is likely to be an underground fire vein."

"Is the small red dot directly in front of the tunnel a reflection of the underground fire veins?" Su Che asked.

"It should be." Lao Hei replied: "The distance is too far, and I can't recognize it like you."

Lao Hei's insight ability is only one hundred feet long, and beyond this range, what he sees is the same as what Suche sees with his naked eyes.

Suche once again stepped over the invisible diaphragm, facing the heat wave coming, his speed of progress could not help but slowed down a lot.

As the distance gradually approached, the temperature in the tunnel became higher and higher. Soon, Suche needed the body of true qi to resist the high temperature. If it were an ordinary person, he had been roasted and placed on the dining table at this level.

Getting closer...

When I arrived at the end of the tunnel, I suddenly realized that it was an extremely open underground space and a strange world of fiery red.

This should be an underground lava river channel. Orange-red magma flows slowly below, and the surrounding cave walls have already shown glazed characteristics, like a thick layer of red crystals, and the normal colors of soil and rocks are basically no longer visible.

Suche walked out of the tunnel and continued to move forward along a narrow path protruding from the wall of the cave on the right toward the downstream of the lava river. This is also the only feasible path, and I don’t know whether it was formed naturally or was dug by man...

After walking nearly a hundred feet, turning a curve, I saw that the lava river converged into a lava lake there. The space here is wider, and the length and width are difficult to estimate. The height is only more than thirty feet.

"A huge and majestic furnace hall!" Suche believed that although such a description was empty, it was very suitable to describe the scenery here.

However, the scenery here is not important. What is important is that Suche saw a small black island raised in the lava lake, which is not large in area, and looks like a radius of more than ten feet in radius.

Directly above the island, a triangular flag is quietly floating. On the golden flag, there are some dark patterns embroidered, and there seem to be two characters. The distance is too far for Suche to see clearly.

The island is not too far away and is within Lao Hei's detection range. So Lao Hei replied: "I can see those two words clearly, but I don't recognize them. It should be a very ancient font. Today's world of cultivation no longer uses this kind of text. I will write down their appearance, look back, find the relevant books and check them carefully."

"This flag can be automatically suspended, it should be a magic weapon, right?" Su Che asked in his heart.

"It must be a magic weapon!" Lao Hei was originally a weapon spirit, and he was particularly sensitive to magic weapon-like objects: "But, he cannot sense whether it has a weapon spirit for the time being."

Su Che wanted to get the treasure at the moment, but he did not forget that there should be a red-tailed fox with great strength here...

After observing around, there was no trace of the red-tailed fox, and Lao Hei also did not detect anything.

Su Che observed the distance. His current location was about sixty feet away from the island in the lava lake. He didn't know how to fly. If he wanted to reach that island, he could only swim through the magma.

Swimming in magma sounds extremely terrible, but in fact, it is just a terrible thing for ordinary people. Cultivators can come up with many ways to accomplish this feat.

For example, Su Che is already in the middle stage of Qi training and can control the top-grade magic weapon. He captured Luo Lianqiao in the Demon Seal Realm and seized his top-grade magic shield. With this magic shield alone, Su Che is not afraid of the high temperature of magma.

However, as soon as Suche took out this green magic shield, he heard Lao Hei's warning: "Something swams over in the magma, and it's very fast... I hid on the other side of the island and stopped temporarily!"
