There are still a lot of insects and snakes in the mountains and forests.

Before the two of them entered the mountain forest, they both tightened their trouser legs and sprayed their bodies with drugs to repel insects and snakes.

These potions were also prepared by Zhen Bao.

It's not difficult to prepare the potions, but it's hard to think about it so thoroughly.

Because he had to travel, Yuan Yuan didn't wear a robe, and he was still dressed in a short suit.

Although the texture of the clothes on the body is good, there are no colors and textures, and they are very simple, so the two of them look like children of ordinary Orion families on the side of the mountain.

After entering the mountains and forests, Yuan Yuan and Wu Daniu knew how difficult the road in the mountains and forests was.

The mountains and forests are too dense, and there are so many plants on the ground that there are no roads at all.

The two of them held machetes in one hand to cut through the plants next to them, and with the other hand, they pulled away the lush plants and opened a path.

After walking for more than two hours, I found no traces of the activities of the velvet mink around, and the sky became dark. The two of them explored some of the surrounding areas to see if there was a suitable place to rest.

Next to a small stream, Wu Da Niu really discovered a cave.

The cave is open on a rock wall.

It looks like a natural cave, and the inside is not very clean, and it is clear that some large animals used to build their nests in it.

The two of them carried a bucket of water, cleaned it up, and then prepared to rest here.

Wu Da Niu hunted a goat by the stream, skinned it, cleaned the internal organs, and brought it back.

Yuan Yuan picked up some firewood and lit a bonfire.

Then, Yuan Yuan put the goat on the fire and began to barbecue.

The goat had some smell, but Yuan Yuan smeared honey, spices, and condiments, and those smells were removed.

The goats brought back by Wu Da Niu. Apparently still relatively young, the meat is very tender.

After roasting the goat, the two ate it separately.

The bonfire was moved to the entrance of the cave, and a thick blanket was spread in the cave, and the two were ready to rest.

Yuan Yuan lay down and was about to close his eyes, when he suddenly noticed some patterns on the top wall of the cave.

The top wall of the cave is very high, more than two zhang, I don't know, who it is. It was possible to draw these patterns on such a high top wall.

The pattern indicates five directions.

Yuan Yuan called out to Wu Da Niu, pointed to these patterns, and then followed the places indicated by these patterns to take a look.

Sure enough, the rock walls in these five directions have a small protrusion.

Because the rock wall is not smooth, and the top is also rocky, if it were not for the pattern indication on the top, these protrusions would not have been found at all.

Wu Daniu followed Yuan Yuan to find these things. Great doubts rose in their hearts.

Who exactly. Left these patterns, organs. What exactly are they leaving these patterns for?

The two looked at each other, then pressed the protrusion on the rock wall.

Press one. I heard the sound of "chirp, chirp".

Apparently the organ was activated.

Press another one, and there is another sound.

Until the two of them pressed down all five protrusions, a rock on the ground. Suddenly moved.

Then a swarthy hole was revealed.

Yuan Yuan and Wu Da Niu looked at each other, and decided to go down and have a look.

After all. I don't know what danger lies ahead, and I don't know what is in this cave, but there is such an amazing thing, and it would be very uncomfortable not to explore it.

Wu Da Niu wanted to go ahead, but Yuan Yuan took the lead.

The two of them walked down the hole.

Inside the entrance is a tunnel.

As soon as the two of them entered the tunnel, the rock above suddenly closed.

Wu Daniu and Yuan Yuan pushed hard, but they couldn't push it.

The two looked at each other.

Yuan Yuan said, "Since the entrance to this cave is blocked, let's go down, maybe there is something in front of us that can enter and exit." It's a pity that those felt blankets are all pure wool. ”

Wu Daniu nodded.

Although the exit path was blocked, the two did not panic much.

They believe that they will find their way out.

The two looked at the long tunnel.

On the rock wall next to the tunnel, there are still quietly burning oil lamps.

I don't know what kind of oil is used, it's been so long, and it's still burning.

Yuan Yuan secretly thought that it wouldn't be the oil extracted from the merman's body. Legend has it that the oil extracted from the mermaid can burn for thousands of years without extinguishing.

The two of them walked down the tunnel.

The tunnel was sloping, and it was clear that they were going underground.

After walking for about half an hour, they walked out of the tunnel and arrived at a very wide natural cave.

The cave is very large, also very wide and very high.

To the surprise of Yuan Yuan and Wu Daniu, in this cave, there was actually a palace built by man.

The palace is more than a foot high, and it is all made of stone. The style is very old, like the Baroque style of thousands of years ago.

The façade of the palace is a colonnade with twelve monumental columns with elaborate carvings on the capitals.

"Young master, there should be good things in this palace, let's go in and take a look. Wu Daniu said.

Yuan Yuan nodded, "Naturally, since you are here, you naturally have to take a look." ”

With that, the two walked through the colonnade and then walked to the gate of the palace.

With a gentle push, the door opened, and the two walked in.

Walking into the palace, the two of them were very surprised.

The side of the palace is very warm and warm, as if soaking in the warm hot spring water.

On the other side of the palace, it was cold and swishing, as if it had entered the early winter season.

At the front of the palace, there is a high platform, on which there are four exquisite porcelain bowls.

On each porcelain bowl, a flame burns.

There are two clusters of flames on the left, one golden and the other red.

The two clusters of flames on the right, one blue and one purple.

Yuan Yuan approached, only to find that whether it was the warm feeling just now or the cold feeling, it all came from these four clusters of flames.

Golden and red flames. Exudes a warm scent.

Blue and purple flames, emitting a cold aura.

When the two approached, they saw that on the high platform where the flames were placed, words were engraved.

In front of the golden flame, the words "Golden Crow Fire" are engraved.

In front of the red flame, the words "Tianyang Fire" are engraved.

In front of the blue flame, the words "Cold Frost Fire" are engraved.

In front of the purple flame, the words "Ice Silkworm Fire" are engraved.

Yuan Yuan was curious, and it could be seen from the warm and cold situation in the main hall. These four clusters of flames are not simple.

But I don't know, what these flames are used for.

Yuan Yuan and Wu Da Niu searched around, and really let them find something.

There is a small mechanism at the bottom of the high platform, and when you press it down, a small box pops out, like a drawer, from the stone platform.

In the box, a quick jade slip was placed.

Yuan Yuan picked up the jade slip. He put it on his forehead and began to read.

After reading the jade slip, the joy on Yuan Yuan's face was indescribable.

Because, Yuan Yuan finally understood the role of these four clusters of flames.

These four clusters of flames. In the jade slip, it is called the alien fire.

It was the owner who built this palace and tried his best to find it.

This strange fire, if it is subdued by the warrior. It will be of great benefit to the warriors.

In order to subdue the different fires, it is necessary to subdue two different fires at the same time, one is warm. A kind of cold.

The two different fires with different properties are included in the dantian, and the two different fires will form a balance in the dantian, which will be endless, guiding the aura and entering the body.

It will make a martial artist, even when he is not practicing, attract aura into his body.

Moreover, the alien fire is also a domineering combat tool.

Whether it is a cold type of fire or a warm type of fire, it can be used in battle. And it's very powerful.

Naturally, the different fires with warm attributes are the best choice for killing people and destroying corpses.

At that time, the owner of this palace collected these four kinds of fire, which were originally intended to be used by himself.

However, he found that these four different fires did not match his physique. His physique can't contain this strange fire to grow up and become stronger.

In other words, even if he subdued any two of these four different fires, it would be very difficult for him.

Because the alien fire doesn't get stronger.

And the weak alien fire doesn't have much effect on the master here, a martial artist of the Ninety-Nine True Realm.

There is another reason why the owner here has not subdued the strange fire.

That is, the owner here does not have a black jade spirit stone.

When the alien fire is subdued, the meridians and body will be damaged.

Of course, after subduing the alien fire, these injuries can be slowly healed, but if there is a black jade spirit stone, it will make the damaged meridians and body get better in an instant.

Because the nature of the alien fire is very tyrannical.

Whether it is the strange fire of the warm attribute or the doubt of the cold attribute, during the period when the meridians of the martial artist enter the dantian, the meridians of the martial artist will be damaged.

If there is no black jade spirit stone, the damaged meridians may take a long time to heal.

And the master here, during that time, happened to have a fight with someone, so, after thinking about it again, he still didn't subdue the strange fire.

And Yuan Yuan speculated that after the fight was over, the owner here never returned here.

That's why these four clusters of strange fires were left.

It seems that he has anticipated his future a little, so the master here has described the things about the alien fire in detail in the jade slip.

Including how to confirm whether the different fire and your own physique are compatible, and how to accept the different fire.

In the future, how to cultivate different fires, make different fires stronger, and so on.

There is also a very important use for alien fire, and the owner here also said it.

That is to use the alien fire of the warm attribute to alchemy.

The master here left a message, if anyone is lucky enough to subdue two of these different fires, they must also inherit his alchemy inheritance.

If you subdue the alien fire and don't inherit his alchemy inheritance, you can't get out of this place.

Yuan Yuan didn't care about these things, he carefully read the part on how to test whether the different fire and his physique matched, and told Wu Da Niu all about them.

Then, Yuan Yuan asked Wu Da Niu to test first, which kind of alien fire matched his physique. (To be continued.) )
