This is a dark red cliff as high as more than 100 zhang, and a black hole is exposed more than 10 zhang high from the ground, the hole is only about a few zhang in size, and it looks like a black scar on the cliff from a distance.

As soon as Han Fei approached this rock wall, he felt a strong aura of fire attribute rushing towards him.

According to the information he had, this was a huge red gold vein in the past, and the content of red gold was extremely rich, which allowed Jiang Yunzong to mine for thousands of years, and it was not completely abandoned until more than a thousand years ago.

Since this area was extremely remote, it had bred many low-level demon beasts, and it was not too far from Jiang Yun Sect, so it became a place of trial for the disciples of the Diligent Palace.

Red gold is a primary-level material with fire attributes, but its quality is much higher than that of Xuantie, and it is a good material for refining high-grade magic weapons and even top-grade magic weapons.

Even if it has been abandoned for nearly a thousand years, the fire attribute aura in it is still strong, because it has attracted many fire attribute demon beasts to entrench here, but since it became a place of trial, the stronger monks have either been killed or driven away, leaving only the demon beasts below the third order to survive here.

Han Fei didn't remember to enter the Fire Cloud Cave, but instead took out the jade talisman first and checked the general terrain of the Fire Cloud Cave again.

However, this map is relatively rough drawn, and only identifies more than ten main passages and dozens of large forks in the Huoyun Cave, but from these points alone, the entire range of the Huoyun Cave is hundreds of miles in a radius.

After pondering for a while, Han Fei jumped forward, stepped on the Red Scale Sword and escaped into the Fire Cloud Cave.

After entering the Fire Cloud Cave more than ten zhang deep, Han Fei put away the Red Scale Sword, and after probing the direction with his divine sense, he chose a main passage to enter it and began to rush forward in the darkness.

According to Han Fei's plan, there were only a few days left before the end of the trial, so he planned to enter through this main passage and then return along the other main passage, and how much he could gain was up to his luck.

Almost two hours later, Han Fei encountered the first demon beast, this was a second-order gold-eating beast, this beast was not too big, it was not more than a foot in front and back, but the speed was indeed extremely fast, and the darkness around it did not have the slightest effect on it.

The gold-eating beast is like an ordinary demon rat, but its tail is much shorter, and the proportion of its head is much larger than that of ordinary demon rats, and its body is covered with dark red hair, and its neck has a circle of red stingers more than a foot long, and its roots will stand up when it is angry.

Coupled with its four sharp fangs that emerge from its mouth, it looks very ferocious and terrifying.

The passage was relatively narrow, so it was not conducive to Han Fei's dodge during the battle, so the battle was almost equivalent to hand-to-hand combat.

Seeing this, Han Fei took advantage of the opportunity of the gold-eating beast to attack him, and his body dodged to the back of the gold-eating beast, and then continued to run forward, while the gold-eating beast let out a few piercing screams before continuing to chase after Han Fei.

During this time, Han Fei had already felt some rules of the passage, and every ten miles of passage, there would be an open field, the small ones were more than ten zhang in size, and the large ones were dozens of zhang in size, so Han Fei planned to lure the gold-eating beast there and solve it again.

The screams of the gold-eating beasts were so piercing that after Han Fei heard these sounds, his mind couldn't help but feel restless, originally Han Fei felt that he had little chance of winning against this second-order gold-eating beast.

But when he found that the beast was angry, it glowed with a faint red light, allowing him to see its presence in the dark, and he was a little more sure.

After half an hour of fierce fighting, Han Fei finally solved the gold-eating beast, but he also caused three more wounds on his back, which were caused by the gold-eating beast's sharp claws.

It was impossible to see the wound in the dark, but apart from the burning pain on Han Fei's back, something sticky was slowly flowing out of the wound.

Immediately, Han Fei took out some gold sore medicine and applied it to the wound, then took out a coarse cloth to temporarily bandage the wound, and after treating his own injuries, Han Fei took care of the corpse of the gold eating beast, and then continued to move forward.

The Fire Cloud Cave is indeed much more dangerous than the outside, and the first demon beast he encountered after he came in was a second-order demon beast, and his strength was a few points stronger than the strength of the second-order demon beast outside.

But the harvest is far more than the outside, not to mention the trial points, just the materials on this gold-eating beast are worth dozens of low-grade spirit stones, and the stingers on its neck and the claws on its limbs are some usable primary-level materials.

And in the past few days that Han Fei has been outside, he has killed a lot of second-order demon beasts, but there are almost no materials that can be used.

Han Fei had just gone deeper than ten miles into the land, and suddenly there was a disturbance in front of him, except for the roar of a demon beast, as if he heard a few sounds of "run", and at the same time, the sound of gold and iron was also endless.

In this way, it seems that there is a trial disciple ahead who has encountered a powerful demon beast.

Without further ado, Han Fei saw that there were several forks in the nearby rock wall, and when he chose a place to dodge into it, and then ran several miles away in one go, he slowed down.

Just now, his divine sense had already sensed that there were as many as three trial disciples in the fierce fight, and all of them were cultivators of the fourth level of qi refining, so their strength was still inferior, and the demon beasts they encountered must be above the third order.

With his current strength, he can barely cope with a second-order demon beast alone, if he encounters a third-order demon beast, he can only escape, and if he encounters a third-order demon beast with relatively strong strength, he will not even have a chance to escape.

Although the praying mantis catches the cicada and the yellow finch is behind, the strength of the mantis and the cicada is too strong, and the strength of the yellow finch is too weak, I am afraid that not only will it not be able to pick up any cheapness, but it will also take its own life.

When he came back to his senses, Han Fei found a serious problem.

Just now, I panicked, entered such a small fork in the road, and ran such a long distance in one breath, only to find that there were more small forks in the fork, and I couldn't find which one I just came in?

None of these forks may be too long, but there are so many of them that they are criss-crossed and difficult to tell in the dark.

After pondering for a moment, Han Fei had an idea, and for now, he was afraid that he could only make a mark on the rock wall while moving forward, so as to prevent himself from just turning in circles in place like a ghost hitting a wall.

I don't know how long it took, but I only knew that I had killed five or six second-order demon beasts during this time, and after going around for a long time, Han Fei finally turned back to a living passage, which made him feel much more relieved.

The cave was so dark that after staying for a long time, he didn't know how long it had been? Han Fei could only take out the jade talisman and glance at it, according to the mark on the jade talisman, there were only five days left in the trial.
