It's not an exaggeration to call it a lake, a turquoise water, exuding energy fluctuations and vitality that can lift people's spirits with just a sip of it.

"Poof! Poof! Poof! ”

Suddenly, the air squirmed slightly, and several falling sounds came, and five figures with not weak breath fell into the pool one after another.

"There isn't much time, each of the five of us has a corner, and we should hurry up and cultivate."

Lin Dong's suggestion made the five of them immediately sit in the pool in a five-cornered posture and enter the cultivation state extremely quickly.

They could only stay in the Holy Spirit Pool for a month, and they had to seize all the time to extract the energy in the pool water to cultivate and lay the foundation for entering the Nirvana realm.

"The Great Realm of Darkness!"

Looking at the four people who were quickly settled, Lin Dong smiled slightly, and the thick darkness quickly surged out of his body, rendering the corner of the Holy Spirit Pool he occupied into a dark realm, covering all the eyes that might be peeping into the outside world.

The outside world is dark, but the inner world is like daylight.

"Boy, are you planning to let that stupid tiger soak in this Holy Spirit Pool?"

The air rippled rapidly, and a thin figure emerged.

"Roar!"

As soon as the mink finished speaking, a red kitten immediately burst out of Lin Dong's arms and quickly swelled to a hideous tiger beast about ten zhang in size.

"Well, Xiao Yan has already stepped into the half-step Nirvana Realm, and this Holy Spirit Pool is condensed by the essence blood of the ancient divine beast, just so that it can use the power of this pool of water to impact the Nirvana Realm."

Lin Dong touched Xiao Yan's head, and soon it will be able to turn into a human form, I am really looking forward to it.

"Well, yes, it stands to reason that the stupid tiger has eaten so many Nirvana Pills from you for most of the past six months, if you can't succeed in breaking through, you can just kill it."

The little mink rubbed his chin and nodded approvingly.

"Roar!"

Xiao Yan, who was quite intelligent, obviously understood something, and immediately roared at Xiao Mink.

"Okay, stop playing, I can sense a faint coercion at the bottom of the pool, I'm afraid that the ancient beast has fallen here. Little mink, you go down and take a look at the situation, if it's true, maybe you can get some benefits back. ”

Lin Dong's eyes looked directly at the bottom of the pool, and his spiritual power had already achieved that of the Second Seal Heavenly Rune Master, and he could clearly sense the savage and domineering hidden coercion below.

"Did you sense it? In my opinion, the cultivation of this ancient divine beast during its lifetime should have surpassed the Nirvana realm, and it was an existence that had stepped into the realm of life and death. If we can find its skeleton and find its natal essence blood and demon spirit there, maybe I can go further with Stupid Tiger. ”

"You look at the stupid tiger, I'll go down and take a look, and I'll be back soon."

The little mink nodded, turning into a purple-black glow and plunging headlong.

"Xiao Yan, let's start, I'll help you protect the Fa, this time you must step into the Nirvana realm, don't let me and Xiao Mink down."

Lin Dong patted Xiao Yan and encouraged.

"Roar!"

Xiao Yan's hideous tiger eyes suddenly flashed a bright color, nodded the tiger's head heavily, and immediately closed the tiger's eyes and crouched in the pool of water, exhaling and inhaling, there were ripples of turquoise energy along its hair into his body.

"Slow, still too slow, let me help you."

Lin moved his fingers to draw a circle in the void at random, and the rich devouring power immediately surged under Xiao Yan's body, quickly condensing into a hundred-zhang long vortex black hole, making it exactly in the center of the black vortex.

"Buzz!"

As the whirlpool black hole rotated rapidly, the surface of the water surged violently, and the turquoise energy in the pool was extracted by the devouring force, and frantically poured into the body of the tiger beast in a crazy attitude.

As the energy of the pond water continued to enter his body, Xiao Yan's red hair became brighter and brighter, and his breath became more and more obscure.

For a while, the surface of the pond was completely calm.

A day later, a purple-black glow burst out of the bottom of the pool like lightning and landed in the dark barrier.

"How's the catch?"

Lin Dong, who was sitting cross-legged with his eyes closed, opened his eyes.

"Hehe, how can there be a reason for the mink master to lose, the beast corpse under the bottom of the pool is an ancient crocodile, and it should be a demon beast that stepped into the Death Mystery Realm before his death, and he fell here for some reason."

"Part of the essence blood that flowed out of the wound condensed into the Holy Spirit Pool, which was later discovered by the Great Yan Imperial Family, and used it as a base to open up a country. You see, what is this? ”

With a wave of the mink's claws, two light clusters that emitted rich energy fluctuations immediately appeared in front of Lin Dong's eyes.

One is a mass of gray-red essence blood that constantly wriggles, like living life.

One is a simple white bone gun, the whole body is round, the material is like jade, and the faint cold light at the tip of the gun reminds people that this is not an extraordinary thing.

"Ancient Celestial Crocodile's Natal Essence Blood and Natal Spirit Treasure?"

Lin Dong glanced at them and recognized their origins.

"Well, this Holy Spirit Pool is only coagulated by some of the essence blood that flowed out of the wound of the ancient heavenly crocodile, and most of the rest is still left in its beast corpse.

"Although the Holy Spirit Pool of the Great Yan Dynasty may have been completely abolished since then, it doesn't matter, after my brothers and sisters are developed, I will come back to compensate them."

The little mink smiled rather treacherously.

"Coagulated by most of the blood of the ancient celestial crocodile? The essence blood of the ancient divine beast was of great benefit to Xiao Yan, if it could completely digest it, it would be able to set foot in the five-element, no, seven-element nirvana realm in the future. ”

Lin Dong nodded secretly, he was not the kind of pedantic person.

The Holy Spirit Pool is opened once in twenty years, how can he achieve the peak powerhouse of the Tianxuan Continent after twenty years, not to mention a secret realm of the Great Yan Dynasty, that is, to upgrade it from a low-level dynasty to the top ten super dynasties, it is also a casual matter.

"Don't stuff the essence blood of the ancient heavenly crocodile to Xiao Yan for the time being, it is currently a critical moment to impact the Nirvana Realm, and digesting the essence blood of the xenomorph divine beast will only distract it."

Lin Dong made a casual move and took this gray-red essence blood into his arms.

"You see, this bone spear is a natal spirit treasure refined by the ancient crocodile from its own bones." Mink continued.

Demon beasts with strong strength (at least in the Nirvana Realm) or bloodline inheritance will usually refine one of their body parts into a natal spirit treasure using secret methods, which may be the hair, skin, tail, and even teeth that naturally fall off their beast's body.

It is also possible that it deliberately cut off a powerful part of the beast's body and then refined it into a natal spirit treasure.

Anyway, the raw materials of the natal spirit treasures of all kinds of demon beasts are strange, only you can't think of it, and there is nothing that the big demons can't do.

Ahem, of course, there are also some sources of raw materials for the Natal Spirit Treasure, which are definitely something that the Terran powerhouses will never want to know, which is simply ruined.
