The inside of the cave was pitch black.

Ye Mu released the Eastern Emperor Golden Bell, the golden light, instantly illuminated the entire cave as bright as day, only to see that this cave is very deep, and extends in all directions, full of forks in the road, like a labyrinth.

"Where do we go?"

"Where do we go?"

Su Ziyan frowned, looked around with some concern.

Ye Mu's eyes flashed, and he ran the Qiankun Divine Mirror in his body, and in an instant, he felt that in the cave on the far right, there was an extremely powerful spiritual power fluctuation coming.

"Such a strong spiritual power fluctuation, is it some kind of heavenly treasure?"

Ye Mu's expression moved, and he walked towards the cave with Su Ziyan.

Following the cave, Ye Mu and Su Ziyan came to the inside of the cave, and their eyes suddenly opened up, only to see that in the center of the huge cave, there was an underground lake with a size of dozens of miles.

Right in the middle of the lake is a huge white stalactite.

"Stalactite Spirit Stone!"

The moment he saw the boulder, Ye Mu was shocked in his heart, and a look of surprise appeared in his eyes.

Stalactite spirit stone!

It is a heaven and earth spiritual object formed by the convergence of spiritual energy, and the heaven and earth spiritual energy contained in it is extremely rich, even if it is a superb spiritual crystal, it cannot be compared at all.

Therefore, under normal circumstances, even a palm-sized spirit stone is a priceless treasure.

And such a large stalactite spirit stone in front of you, if you take it out, I'm afraid it will be a sky-high price!

Ye Mu never dreamed that such a treasure would be hidden in this seemingly inconspicuous cave, which was incredible.

"If I cultivate on this stalactite spirit stone, plus the golden body relics, in two months, my cultivation is estimated to be able to reach the realm of the earth element double, and even the earth element triple is very possible. ”

Ye Mu was quite excited in his heart.

Su Ziyan was also pleasantly surprised: "I didn't expect this treasure map to be real, there are really such treasures here, let's go up and cultivate." ”

Su Ziyan couldn't wait.

But just when she raised her foot to get up to the stalactite spirit stone.

Ye Mu suddenly grabbed her and said, "Wait!"

"What's wrong?"

Su Ziyan turned her head to look at Ye Mu, but saw Ye Muzheng looking at the underground lake below the stalactite spirit stone with a rather solemn expression.

"All heaven and earth spirit creatures have spirit beasts, such a large stalactite spirit stone, how can there be no spirit beasts to protect it? If that is the case, I am afraid that it has already been taken away by someone, and it will not be your turn at all," Ye Mu said lightly.

"That's what you said, it's just that where are the spirit beasts here, why didn't I see them?" Su Ziyan frowned and scanned the surroundings, not to mention any guardian spirit beasts, but she couldn't even see a ghost.

Ye Mu snorted coldly: "There is a black water snake hidden in this lake. ”

What the!

There's the Black Water Snake!

Hearing this, Su Ziyan's face instantly turned pale and bloodless.

She naturally knew the power of the Black Water Snake, it was the overlord among the fourth-order and fifth-grade spirit beasts, not to mention them, even those intermediate students, who did not dare to provoke easily.

"What then? Let's go back and find helpers, the Black Water Snake is not something we can deal with. ”

"If you are looking for a helper, do you think this stalactite spirit stone will still belong to us?"

Ye Mu shook his head and said, "Although this stalactite spirit stone is not small, it is at most enough for the two of us to cultivate, I don't want to give it to others again." ”

"But ......"

"Don't worry, it's just a fourth-order and fifth-grade spirit beast, I'll deal with it. ”

"How do you deal with it?"

When Su Ziyan heard this, her eyebrows immediately raised, and her eyes were full of doubt.

Isn't it a joke for a true Yuan ninefold martial artist to deal with a fourth-order five-grade spirit beast?

Ye Mu smiled mysteriously: "You look at it on the side, I will teach you a set of formations today." ”

Finished!

Ye Mu took out five array flags from the space ring, only to see that these five array flags were white, blue, red and yellow five colors, which corresponded to the five elements of gold, wood, water, fire, and earth, which Ye Mu had specially prepared these days.

With a flick of his wrist, five flags shot out and planted around the waterhole, forming a pentagonal shape!

Ye Mu immediately hooked the corners of his mouth, and then jumped forward, jumping towards the stalactite spirit stone.

That's it!

The waterhole below suddenly surged violently, and a huge wave rose into the sky, and immediately I saw a huge snake head the size of half a house rushing out of the waterhole, opening its bloody mouth and biting towards Ye Mu!

"It turned out to be really a black water snake, Ye Mu was careful......"

Ye Muren was in mid-air, a disgusting fishy wind came to his face, seeing that the big mouth of the black water snake was about to bite him, I saw a sarcasm on the corner of his mouth, his hands quickly pinched the magic trick, and then he shouted in a low voice: "Five Elements Trapped Spirit Array!"

Boom!

I saw that the five flags suddenly released dazzling light, and then the white, blue, red, and yellow five different colors, but the thick light locks shot out from all directions, instantly entangled the body of the Black Water Snake, and trapped the Black Water Snake firmly in mid-air.

The black water snake roared and struggled, and its brutal strength almost broke free of the five chains.

Seeing that the five chains still couldn't trap the Black Water Snake.

Ye Mu immediately snorted coldly and released the Eastern Emperor Jin Zhong and Xiao Jin at the same time.

Xiao Jin turned into a huge golden giant ape, holding the Eastern Emperor Golden Bell, and smashed it hard at the head of the black water snake.

Rumble!

With a loud bang, the black water snake shook its head a few times, but it did not suffer the slightest damage, but instead flicked its huge tail and directly blasted Ye Mu out.

"Hmph, it's worthy of the Black Water Snake, it's really powerful, but it's a pity that you met me......"

Ye Mu sneered, and the Qingying Ancient Sword was erected high, and in an instant, the human sword became one, and it stabbed towards the abdomen of the Black Water Snake like lightning.

The location that Ye Mu stabbed was exactly where the demon pill of the Black Water Snake was located, and it was also the weakest place of the Black Water Snake, once it was broken, it would definitely die.

The black water snake seemed to have guessed Ye Mu's intentions, and roared again and again, and its thick tail was suddenly afraid of hitting the surface of the water, setting off waves and blasting towards Ye Mu.

"Broken!"

Ye Mu let out a low snort, the light of the Qingying Ancient Sword surged, the wind howled, and it turned into a terrifying stegosaurus, which instantly broke through the waves, and stabbed towards the vital point of the black water snake like a broken bamboo.

This sword is extremely fast!

The huge body of the black water snake didn't even react before it was pierced by a sword, and dark red blood gushed like a spring, instantly staining the entire waterhole.

The black water snake roared unwillingly, and then fell to the ground.

The dignified fourth-order and fifth-grade demon beast died in Ye Mu's hands like this.

Seeing this scene, Ye Mu suddenly breathed a sigh of relief, and immediately his eyes flashed, and he looked at Su Ziyan, who was stunned and almost stupid, and said, "Come here, this guy is dead." ”

Su Ziyan reacted at this time, and looked at Ye Mu with a shocked expression, her eyes as if she was looking at another monster.

"Senior Brother Ye, you are too strong, you can even use this kind of high-level formation, how strong is your spiritual power, how did you do it?"

"I'll explain to you later, let's hurry up and cultivate. ”
