Proficiency: practice thousands of times

In the distance, at the boundary of the Earth Fissure, there is an underground cave.

At this time, a black-robed man was fighting with a gray-spotted tiger.

The hood of the man in black was torn to pieces by the tiger's claws, and half of his face had claw marks with deep bone visible, dripping blood.

His face was old, and his long beard was already grey.

But the energy and blood in his body was very surging, and there was no sign of weakening at all.

Still a powerful warrior at his peak!

It's a pity that this gray stone tiger is also difficult to deal with. With a strong tiger body, it is not easy to break through the defense, making it difficult for the man in black to fight.

"Damn idiot, he died so fast!"

The man in black saw some scraps of meat, a few scattered human organs, and half of a finger stuck between his teeth around Dumb's mouth, so he knew that his companion was dead.

He thought that the other party should be able to delay longer, but who knows that it will only take a while.

Before he had time to explore the underground cave, the guarding tiger came back.

He calculated and calculated, but still made a mistake.

He overestimated the strength of his peers and underestimated the threat of Dumb.

"It seems that the cave is where the stalactites are hidden."

Wang Yu watched the human-tiger battle without any sense of existence, and at the same time, he also discovered the underground cave that appeared because of the crack in the ground.

It's just that the big tiger made him quite afraid.

The intensity of Qi and blood of the black-robed man is at least above rank four, and his strength is much stronger than that of Luo Chu.

But that's it, under the bite of the big tiger, he obviously couldn't hold on.

The big tiger was too fierce, even Wang Yu couldn't do anything with it guarding him.

"It's really not possible. Taking the corpses of these two people back to the mission, there should be a lot of merit." Wang Yu thought to himself.

You can't come here for nothing.

After all, his current cultivation base is too low, and he is really not sure about dealing with this big tiger.

After returning to the military headquarters, I will find someone to come with me.

It's just that when the time comes, it's hard to say how much of the benefits in the cave will be shared.

Chapter 84 Geocentric Stalactite

It has to be said that Wang Yu's judgment was very accurate. Although the black-robed old man had tried his best, it was still difficult for him to cause more damage to this gray stone tiger.

As soon as he gritted his teeth, his figure flew away, turned around and left.

Dumb is not willing to let go of the food in his mouth.

The more human warriors are full of energy and blood, the more nourishing they are in the mouths of these fierce beasts.

On this point, both sides are surprisingly consistent.

Dug was about to pounce on him, but the man in black suddenly pulled out a green stone and threw it at Dug.

It's not an air blast rock!

The air-explosive stone exploded with a bang, a small one, but its power is really not small.

Fortunately, Wang Yu watched from a long distance, and was not affected by much explosion.

On the contrary, the man in black was too close. Under the impact of the explosion, his body was damaged and he vomited blood from his mouth.

Run towards the distance with the impact.

The gray stone tiger was finally broken this time, and its gray hair was burnt black.

However, after being injured, Duhu became even more crazy and chased after the man in black.

Several vertical jumps disappeared in the forest.

"..."

Wang Yu's thoughts flooded his mind for a moment.

Near the cave, there was silence at the moment.

The open door, without any hindrance, seemed to welcome his arrival.

"Maybe this is the outdoor opportunity that the master said!"

Wang Yu suddenly remembered the words when he chatted with Sun Chengshan and spanked.

Luck is something that cannot be explained clearly.

Some people were walking in the wild, and when they turned their heads, they were eaten by wild wolves.

Some people are careless, but they can encounter great opportunities.

During Sun Chengshan's 20 years of martial arts practice, he has also traveled around and met many people and things.

Sometimes when I get excited, I will talk to Wang Yu.

Listening to the sound of the tiger howling in the distance gradually faded away.

Dumb will come back eventually, but there is still a period of time in between.

Do you want to fight?

If you don't give it a try, then why am I here!

In an instant, Wang Yu rushed out of the bushes and quickly stepped into the cave.

He believed in his current ability. With the pursuit speed shown by the big tiger just now, even if he couldn't beat him, he would still have no problem running.

Seventh-level leg skills plus the ability to escape from the blood shadow method is not a joke.

Not to mention that the big tiger was also injured, so it was somewhat weaker.

The interior of the karst cave is much wider than Wang Yu imagined, and the terrain goes all the way down, with layers of layers that can't be seen bottoming out.

I don't know how long this natural cave has been buried deep in the ground. Most of the rocks inside have been crystallized. There is a green color in the white stone, and huge stalagmites hang down from the top.

The air is very humid, causing the entire cave to be filled with water vapor, and water droplets hang everywhere on the rock wall, which is dazzling to see.

"How do you find it so big?" Wang Yu frowned secretly.

Looking at this cave, it was as if the entire ground had been hollowed out.

In such a large place, it would take hours to find the so-called stalactites in the center of the earth.

Not to mention that Wang Yu is running out of time now, and Hui Shihu will come back anytime after eating and drinking.

"It doesn't matter, let's find it first." Wang Yu moved and began to move at high speed in the cave.

In such a big place, even if Dumb came back, it would not be easy to catch him.

Recall in your mind the relevant information about the stalactites in the center of the earth that you have seen before.

Since this thing is formed by the steam from the center of the earth, it must be in a place with a higher temperature.

The overall environment of the cave is cold, so as long as I am fast enough, I can still filter out possible locations in a short time and find them.

Thinking of this, Wang Yu stomped heavily, and his figure suddenly stopped.

Then the whole person was like a spring, suppressed to the limit and suddenly popped out.

The speed is fast, but it is silent, there is not much impact, and there is not even any wind.

A glimpse flashed across the entire cave.

He was at full speed, and now his bursting speed in a straight line is at least double that of before.

If the state of burning blood is activated, this speed can be even higher.

boom!

At the extreme speed, Wang Yu didn't control properly for a while, he rushed too fast and jumped too high, so that he smashed the stalagmite hanging from above.

Fortunately, Wang Yu's head is iron, so he won't be hurt.

He also didn't expect that after strengthening his legs, his speed could increase so much.

I was used to driving a bicycle, but suddenly changed to a motorcycle, so I couldn't get used to it when I hit the accelerator.

Shaking his head, Wang Yu took a moment to pay attention, and then slowed down a bit.

Soon he confirmed that there were no other ferocious beasts in the cave except for the big tiger.

As for the location of the heat source, it is not so easy to find.

The interior of the cave is criss-crossed, and the crystallized rock walls are everywhere, blocking the way like a maze.

Wang Yu was so annoyed that he didn't care about anything else, so he simply smashed and flattened all the rock walls blocking the road with his fists.

After a while, he finally found the deepest part of the cave.

It was a rock pillar connected up and down. The interior of the rock pillar seemed to be hollow and there was high temperature.

A trace of water vapor emerges from the small holes on several rock pillars, adheres to the surface of the rock pillars, and can condense into a drop of liquid after a long time.

This droplet is not milky white, but reddish yellow.

The most amazing thing is that the inside of the liquid bead is hot, and it falls into a circle of rock grooves beside the rock pillar.

Wang Yu saw that a small puddle of reddish-yellow liquid had gathered in the groove of the rock, about the amount of a small cup.

"Earth Clock Emulsion, with scorching properties, pure gold has the best luster, a drop can be worth tens of thousands of broken crystal coins, crimson is the worst, and its efficacy is relatively weak."

Wang Yu recalled all kinds of information about the earth clock emulsion in his mind.

The red-yellow droplet in front of my eyes is actually considered to be of medium quality in stalactite, although it is not as expensive as pure gold.

But such a cup is probably worth more than [-] broken crystal coins, or even higher.

Definitely a priceless item.

Sell ​​it?

Of course not, this kind of treasure that money can't buy is actually quite a loss when exchanged for money.

Even if Wang Yu didn't use it himself, he would exchange it for something equally precious and rare.

In short, put the baby away first!

Wang Yu took out a small porcelain bottle on his body, poured out a few hemostatic medicines inside, and threw it aside without any distress.

Then go forward and carefully fill in all the earth clock emulsion.

After the packaging was completed, Wang Yu only felt that his worth had skyrocketed.

"This is really a good place." I sighed in my heart.

Although the geocentric clock emulsion may not be able to produce a complete drop in half a year, it is a treasure of sustainable renewable resources after all.

And such a precious stalactite!

It's a pity that when the military headquarters takes over here in the future, there will be nothing wrong with him.

But at least he has already won the first place, such a small cup, I don't know how many years it will take to settle it out.

Perhaps that gray stone tiger had spoiled the stalactite here before him.

Thinking of this, it is inevitable to feel a little pity, but Wang Yu is also content.

Before the gray stone tiger returned, Wang Yu immediately wanted to run away, and finally his eyes skipped the location of the stalactite.

I wanted to remember this location, but found that the innermost rock wall seemed to be different.

With a heart move, I took a few steps closer to observe.

It was found that on the solid rock wall, there was a thin crack that went from the top to the ground.

There is a faint light shining through such a long strip.

"There is a universe inside!"

Wang Yu's spirit was shaken. Just now, his attention was all on the geocentric clock emulsion, and he didn't notice the abnormality of this wall at all.

Only now did I realize that there might be an unknown space inside the wall.
