Now Chen Fei's heart is bright, and he must quickly improve his strength in order to rescue his doppelganger's Yuan Shen.

Huang Hao and Fei Bin did not hesitate and followed Chen Fei into the mine.

They are all smart people, they have all experienced too many dangers, their hearts are clear, now in this place, even if they don't enter the mine, just go out, they will definitely be misunderstood by countless fellow disciples that they have entered the mine, they will definitely come to rob their treasures, if they don't rob them, they may even be in danger of their lives.

Therefore, it is better to enter the mine cave once.

The cave was dark, deep, zigzag, but of course it was winding downward, and from time to time it merged and crossed with other mines, and even heard footsteps, which must have been the sound of other disciples hunting for treasure.

Chen Fei didn't want to have any conflict with any of the disciples of the Evil Immortal Sect, so he took the two of them to speed up his pace, avoiding any mining cave where there were footsteps.

They didn't pull out any lights, because they used their senses to get a sense of what was going on nearby.

However, as we go deeper, the black fog in the mine becomes thicker and thicker, and it is really like the black smoke, and the evil aura is the same, which makes people's hearts beat wildly. Maybe it's because of the black fog, or maybe it's because of the ban, their divine sense has been greatly restricted, and the distance of sensing is getting closer and closer.

The deeper you go, the wider the cave becomes, in some cases hundreds of meters in diameter.

The pale black soil, if you look closely, the absolutely dried blood, countless white bones lying on the ground, exuding an evil aura.

"True Evil Gate."

Chen Fei muttered, "You have to be careful and put on your armor." ”

"Well, you should be careful, too."

Huang Hao and Fei Bin said gratefully, almost at the same time, they floated their armor out of their bodies, and they stepped on Chen Fei's footprints, and definitely not anywhere else.

This is the common sense of avoiding danger mentioned in the book just now.

To enter the mine, if you are alone, you must step on the freshest footprints.

If it is a group of people, the person behind will naturally step on the footprints of the person in front.

Because it is very likely that you will step on a terrifying prohibition under your feet, or step on some terrifying monster.

"This is the shallow part of the mine, and many monks have been here, so there is not much danger, let's go a little faster."

After Chen Fei finished speaking, he really quickened his pace.

After walking for about five hours, I don't know how far I have gone in.

No footsteps could be heard from the other mines, and the footprints on the ground were completely gone.

Chen Fei had to stop, a look of jealousy appeared on his face, because in front of him, there was a monk from the Evil Immortal Sect who had a hole in his head, obviously even the Yuan Shen had been killed, and the strange thing was that there was still a space ring on the monk's finger.

Obviously, he did not die at the hands of his fellow disciples, but at the hands of the monsters in the forbidden or mine caves.

Chen Fei looked at it carefully, but found no monsters.

So, he slowly bent down, trying to remove the corpse's spatial ring.

"Be careful......

Huang Hao suddenly let out a frightened sound.

"Whoosh......"

Almost at the same time, a flying sword erupted from his mouth, slamming into a black insect that flew out of the cave wall to attack Chen Fei.

"When ......"

The sound sounded like striking iron, and the insects flew upside down into the air, making a terrible sound.

But if you look closely, there are no scars on its body, and it is extremely powerful.

Moreover, it immediately flew over again, just as fast as a bullet, and slammed into Huang Hao's forehead.

Obviously, it hated Huang Hao.

"Look for death."

Chen Fei roared angrily, the knife in his hand moved suddenly, and with a flash of the knife, the insect turned into two halves, and the corpse fell down, rolling on the ground non-stop, and its vitality was actually very strong.

"It's a brain-eating bug that likes to live in groups, and this place is dangerous."

Chen Fei's face became stern, he quickly took off the space ring, and immediately walked back with the two of them turning around, and then turned into another mine.

Continuing to dig deeper and find a place that seemed safe, Chen Fei poured out the contents of the space ring.

There were a whole bunch of them.

It's all a mess.

Two second-level immortal treasures, three golden stones, exuding a strange aura.

In addition, there are several second-level immortal elixirs and a jade bottle.

There were two pills in the jade bottle.

"This is the sweet fragrance pill, blessed are you two."

After Chen Fei finished speaking, he gave the jade bottle to Huang Hao, "One pill per person, wait for a chance to take it, maybe you can break through to the second level of the earth immortal." ”

Huang Hao and Fei Bin's faces showed a deep sense of surprise, and their bodies trembled with excitement.

They clearly knew that the Xinxiang Pill was a very low-grade pill, but the price was not cheap, and it would take 100,000 immortal stones to buy it.

Then Chen Fei cast his gaze on the three golden stones, recalled the contents recorded in the book, and said happily: "This should be the Immortal Soldier Mine, which is a fossil turned into a fragment of an immortal weapon from the previous era, and it is of great value, maybe it can be exchanged for a third-level immortal medicine." ”

The immortal artifact of the previous era collapsed when the universe was broken, and it was originally going to turn into dust after countless years of time, but this fragment is the essence of the immortal artifact, and the level of the immortal artifact must be very high, and it is likely to be a ninth-level immortal artifact, so it has become an ore.

Such an ore can not only refine high-grade immortal weapons, but also may contain the secret refining methods of the monks of the previous era.

Nature is precious.

"Great, it's actually an immortal soldier mine."

Huang Hao and Fei Bin were also pleasantly surprised.

As for those two second-level immortal treasures, they were the least valuable of these treasures.

"Come on, come on, we've divided the treasures."

Chen Fei said with a grin.

"Chen Fei, the two of us are still too weak, and the treasure will be placed there for you."

Fei Bin and Huang Hao glanced at each other, and then said almost at the same time.

"Okay, then I'll take it first."

After Chen Fei finished speaking indifferently, he put away these treasures.

He still doesn't care about such treasures, but no matter how few mosquitoes are, they are still meat, so he is still very happy.

They kept going, slowing down completely, treading in the footsteps of others.

Soon, they came to an open space in all directions, and it turned out that five mines were linked together.

"What's that?"

Chen Fei suddenly sensed a terrifying monster.

It turned out to be a three-meter-tall skeleton, without any muscles or internal organs.

However, he walked in the mine like a ghost, silently.

In his hand, however, he was holding a heart that was still beating, and he made a terrifying sound with a bang.
