Seeing that Yu Ling'er had returned to the Blood Demon Cave, Qin Dong was not surprised, if it was that secret realm, everyone could enter it, and I was afraid that it would not become a secret place.

A little under his feet, Qin Dong's body was like a ghost, following Yu Ling'er's trail, the two of them were a demon, and soon returned to that underground space.

When she arrived at the place, Yu Ling'er had words in her mouth, pinched a few tricks in her hand, and condensed a star map in front of her, and then took Qin Dong into it again according to the "Orion" star position.

On the way, Qin Dong didn't ask why Yu Ling'er knew the way to enter, but picked up the key points and asked, "What is that secret realm called?" Could it be ...... Is this the source of this bloody demon cave? ”

"Yes, you are indeed very smart, you only watched it once, and you guessed it."

Yu Ling'er said with a mysterious face: "There are not many people who know this secret, and it just so happens that this girl is one of them!" Moreover, most of the blood-winged bat demons in the Blood Demon Cave also escaped from this source, otherwise, so many Xianmen disciples often come to harvest, why are those little demons always endless and inexhaustible to kill?! ”

"I see."

Qin Dong was secretly speechless, it seems that this place of trial, like the Ten Thousand Demon Mountain, is divided into two major areas, but there are not many people who know the true secret of the Blood Demon Cave, only some immortal cultivation families, or immortal sect masters, know where the secret realm is.

Just think about it.

Ordinary Immortal Sect disciples, when they come to the trial, if there is no star map to guide them, and no one tells them the secret in advance, how can they find this secret realm from the thousands of blood demon caves?

Moreover, to enter this place, it is not necessary to choose the right Blood Demon Cave and arrive at it, but after entering one Blood Demon Cave after another, you need to go through some special forks in the road to get right, otherwise, just one mistake, you will miss the secret realm, and you will never have a chance again.

In this situation, if you want to rely on chance to discover the secret realm, the probability is infinitely close to "zero", and there is almost no such possibility.

Half an hour later.

With the scenery in front of him, Qin Dong suddenly opened up, and found that he had actually escaped from the Blood Demon Cave and came to a primeval forest.

If nothing else, this place is probably very far away from the Blood Demon Cave.

Along the way, Qin Dong couldn't remember how many forks he had passed, as well as deep and mysterious underground passages, just from the perspective of time, it was at least more than thirty miles away from the underground space.

"Huh? Why are all the stones here black? And the ground...... Also black? ”

Suddenly, Qin Dong discovered that except for the forest, which was as usual, most of it was green, and the stones and ground here were all pitch black, as if they were born black, which was extremely weird.

"This is called the Forest of Dark Stones! Those stones are not ordinary stones, but dark stones, and as for the ground, you should treat these things as 'black soil'. ”

Yu Ling'er patiently explained, but it was the Qingling Ice Flame Snake, looking like an old god, raising its head, like a king, scanning the forest, as if this was its territory.

"These stones are 'dark stones'?"

Qin Dong took a step forward and grabbed a stone at random, just pinched it hard, and found that his strong grip was so strong that for a while, he couldn't grab a dark stone.

It wasn't until he increased his strength that he crushed a fist-sized dark stone, turned it into a stone, and fell to the ground.

This scene couldn't help but make Qin Dong gasp, being able to resist his grip was undoubtedly proof that the toughness of those dark stones was comparable to Jin Tie.

Even, compared to those ordinary gold and iron, it is still surpassed, with great toughness and resistance.

"Yes, these dark stones, I don't know how they were formed, in short, if it is not necessary, you better not get too close to these dark stones, because many demon beasts, especially those blood-winged bat demons, especially like to hide in the dark stones and sneak attack...... Yu Ling'er admonished.

The dark stone is black, and the blood-winged bat demon is also pitch black and lusterless, if it hides behind the dark stone, wouldn't it be an excellent hiding place?

"Whew!"

As he was talking, behind Qin Dong, a sharp roar suddenly sounded, followed by a huge black figure, rushing towards Qin Dong.

That pair of silver teeth, like a sharp cone, went straight into Qin Dong's chest, if he was carelessly hit, this sneak attack alone would be able to end Qin Dong's life in advance.

"It's not good, this thing is not an ordinary Blood-winged Bat Demon, but a Blood-Winged Bat King!"

Yu Ling'er was taken aback, she never thought that there was a Blood-winged Bat King hidden at the entrance, could it be that this demon was dormant here, just to sneak attack?

However, under the shock, Yu Ling'er's reaction was not slow, and with a finger of his hand, he controlled the Qingling Ice Flame Snake, and took the lead in pounced, blocking in front of Qin Dong, wanting to stop this fatal blow.

It's a pity, how could the Blue Spirit Ice Flame Snake, which is in its infancy, be the opponent of the Blood Wing Bat King? As soon as he got closer, he was hit hard by this demon, bounced out, and retreated ten meters away.

Seeing that Qin Dong was about to be bitten by the Bloodwing Bat King and died, suddenly-

"Just a little evil animal, dare to be presumptuous?"

I saw that Qin Dong did not dodge or retreat, and as soon as his five fingers were clenched into a fist, he faced the attacking Blood Winged Bat King, and his qi ran through the mountains and rivers, and he was like a thousand pounds, and he burst out!

He has divine power in his body, and after a fight, he already knows himself, and he is not afraid of this Blood Winged Bat King, and now he has encountered another one, Qin Dong only thought that the other party was giving people heads, and he didn't take it to heart at all.

Sure enough!

Bang!

Under one punch, the Blood Winged Bat King really didn't succeed, but was punched by Qin Dong's powerful punch, making him dizzy, and countless little stars appeared in his pupils, his ears and eyes were buzzing, and he was almost completely deaf!

Looking at the realm of this Blood-Winged Bat King again, it was only in the middle of the fourth order, and it was not much different from Lu Tongjun, Qin Dong's fist was shocked, and he punched hard, smashing on the top of this demon's head.

"Uh......"

The Bloodwing Bat King didn't have time to escape, and he didn't have time to regret it, so he only let out a muffled snort, and then clicked, his neck broke, his head was shattered, and he fell to the ground, dying of anger.

From making a move, to solving a fourth-order demon, that is, the Blood Winged Bat King, with Qin Dong's current strength, it only took a few breaths, as if killing this kind of progressive earth demon beast was as simple as eating and drinking.

"Whew!"

The Qingling Ice Flame Snake suffered a loss, and was waiting for an opportunity to take revenge, but when he saw Qin Dong's backhand, he killed the Blood Winged Bat King, and immediately let out an excited hiss, and then pounced forward, sucking wildly at the Blood Wing Bat King's body, and took that body of essence blood as his own.

For the Qingling Ice Flame Snake, the essence blood of this Blood Winged Bat King is undoubtedly a great supplement, if the amount devoured is enough, it can quickly advance and complete its transformation as soon as possible.

Survival of the fittest, survival of the fittest.

The rules of survival among monsters and beasts are often more cruel than those of the human world.

"Xiaoqing, this is Qin Dong's trophy, and people haven't agreed yet, how can you ......?"

Seeing this, Yu Ling'er smiled, and became a little embarrassed, although the two of them can be regarded as teammates now, but this Blood Winged Bat King was killed by Qin Dong, how could she forcibly occupy it without asking!

"It's okay, this Blood Winged Bat King's essence blood has no effect on me, give it to Xiaoqing, just let it advance, it's wasted, that's a pity......"

Qin Dong waved his hand, and said indifferently, when the little green snake was full and returned to Yu Ling'er, he was unhurried, took out the demon core from the body of the Blood Winged Bat King, and collected the demon corpse, ready to bring it back to the sect in exchange for a part of the merit points.

If it was a third-order demon, Qin Dong wouldn't care so much, this Blood-Winged Bat King had reached the fourth-order, which was enough to be comparable to the human Heavenly Soul Realm, and it must have been brought back to produce extremely high value.

In the Blood Demon Cave, there is no such good thing, you must know that before, Qin Dong and his party of four hunted and killed hundreds of Blood-Winged Bat Demons before they encountered only one Blood-Winged Bat King......

And here, as soon as he entered, he hunted and killed a Blood Winged Bat King, and all kinds of signs showed that this place was indeed as Yu Ling'er said, but it was a secret realm with endless chances!

Fortunately, Qin Dong saved Yu Ling'er by chance, otherwise, where would he be able to get his turn for such a good thing?

"Huh! Why does it smell of blood in front? Could it be that another Immortal Sect disciple has entered the Forest of Dark Stones? Let's go and see. ”

When Qin Dong was secretly happy, not far away, another cold voice suddenly came.

Then came the sound of hurried footsteps, as if the battle here had been discovered, and the others were drawn to come here to find out.
