This is a pure land, wisps of spiritual energy rise from the ground, meet in the valley, if spiritual, it changes various forms in the air. And at the mouth of the valley, a giant ape more than ten feet tall is guarding.

Its whole body is as black as ink, its fine hair is like rain arrows, its two eyes are fiery red and bloodthirsty, and the bare skin on its chest is full of spirit patterns, faintly similar to a human face, and it is actually a strange giant ape that Xia Mu has never seen.

"This Yin Yang Valley is actually guarded by a hegemon-level fierce beast, if I come to break it myself, not to mention whether I can find this place, the mere existence of this overlord-level fierce beast is desperate. ”

Xia Mu was shocked, what he had seen in front of him in the past few days was extremely inconsistent with the record in the jade slip, what was the strongest only at the elite level?

Especially the demon ape in front of him, the fierce aura that permeated his body was far beyond Yun Tianpeng and Yun Giant, it was guarding the mouth of the valley, although it was only more than ten zhang tall, but it gave Xia Mu the feeling that it was like an ancient mountain lying there, tall and majestic.

And the appearance of Xia Mu and the boy in white was also sensed by this demon ape, but after seeing Ling Yao, the demon ape with a fierce face actually knelt on his knees, his upper body was completely prostrate, and he let out a gentle whimper to Ling Yao.

That kind of voice, like seeing the person closest to you, is full of longing and admiration.

Seeing him, Ling Yao's originally lonely face also showed a faint smile, and as soon as his body moved, he shuttled to the top of the demon ape's head with Xia Mu's void, and landed directly on the broad shoulders of the demon ape.

"Atai, let's go. Ling Yao instructed the demon ape and introduced to Xia Mu:

"Atai's body is the Taishan ape, which is as famous as the Zhenshan ape, and it has been with me for almost 600,000 years when the master has not yet shaped the spirit body for me. Although it is now the strongest beast in the Tower of Ten Thousand Worlds, it still regards me as a father, so when the Tower of All Worlds was completely closed, it gave up the last chance to leave the tower and chose to stay by my side. ”

600,000 years? Xia Mu was stunned when he heard this, it seemed that in his impression, the longest lifespan of the overlord-level fierce beast was only 100,000 years, if it was speculated according to such a standard, wouldn't the Taishan ape in front of him surpass the overlord-level?

As if he saw what Xia Mu was thinking, Ling Yao smiled and said, "Except for the turtle-level fierce beasts, which can exceed 100,000 years in life, the rest of the fierce beasts have no special circumstances, and 100,000 years is already the limit. It was also with the help of his master that Ah Tai struggled to break through the bottleneck of the overlord-level and advance to the heaven-level fierce beast. ”

"Senior, is it difficult to advance to a Heaven-Rank Fierce Beast?" Xia Mu asked.

Ling Yao nodded with a calm expression, and said: "It's difficult, the more powerful the bloodline of the fierce beast, the more difficult it is to advance, after all, this world is fair, the average combat power of the fierce beast of the same level is much higher than that of other races, and the lifespan is longer, so relatively, the difficulty of its advancement is naturally much greater than that of other races." ”

"When Atai crossed the catastrophe, even if he had the help of his master, he almost fell, and then he recovered after tens of thousands of years in the Yin and Yang Life and Death Divine Spring. Of course, this also has something to do with its impure blood. ”

Xia Mu said: "What is the specific relationship between the advancement of the beast and the bloodline, why do you have to purify the bloodline in the body until you return to your ancestors?"

Hearing this, Ling Yao smiled indifferently and said, "The things involved in your question are simple and simple, and it is not simple to say that it is not simple, you should know that there are also bloodlines in your human race, and their bloodlines contain the meaning of ancestors." In the same way, the bloodline of the fierce beast also contains the inheritance of their race, only if the bloodline is pure enough, the more inheritance memories it can open, otherwise the inheritance of the beast will become more difficult if it loses the inheritance of the race. ”

"Therefore, purifying the bloodline until the ancestors are atavistic, on the one hand, it is to strengthen itself, and on the other hand, it is also to open more inheritance memories, this is like the sect power of your human race, if you lose the Dao system, it will soon decay and die, on the contrary, if the Dao system lasts forever, the sect will prosper forever, even if there are no outstanding disciples born in the sect in a certain period of time, but as long as the Dao system is still there, there will always be a day when the mountain will make a comeback. ”

For Xia Mu, Ling Yao's words had already been explained very specifically and nuancedly.

While the two were talking, the Tarzan ape had already led the two to the deepest part of the valley.

In the deepest part of the valley, there is a cliff, except for a few ancient pines growing on the cliff, there are no other creatures, and even the aura in the air is much less than the outside world, almost nothing.

Obviously, there must be something in this place, which is wantonly plundering the aura of heaven and earth here, not only changing the density of the aura of the entire valley, but even the vegetation is difficult to grow here.

There was hardly a stop, and when the Taishan ape walked in front of this cliff, he walked through it without hesitation and entered the passage in the cliff.

It was only at this time that Xia Mu discovered that the cliff he had seen before was actually an illusion, or that the cliff did exist, but the part of the Taishan ape passing was false, and it was actually the entrance to a cave.

"Atai, just send it here. Ling Yao instructed Taishan Ape to guard the entrance of the cave, and with a flicker of his body, he took Xia Mu and walked inside along the entrance of the cave.

The area in the cave is quite small, the rock wall is smooth and flat, straight to the depths of the earth, its angle is basically 45 degrees oblique to the ground, along the way, you can clearly see a series of claw marks more than half a foot deep.

The two of them kept walking, flying straight down, and walked for nearly half an hour, Xia Mufang saw that at the end of the dark passage in the distance, a little light suddenly appeared, and as the two approached, the light became bigger and bigger, and finally turned into a passage exit full of green light.

Standing at the exit of the passage, Xia Mu took a deep breath, and Fang Cai followed Ling Yao's footsteps and stepped out of the passage.

The soft green light filled all of Xia Mu's vision, looking around, when the surrounding environment came into view, Xia Mu's face couldn't help but show a touch of consternation.

This is a quiet underground world, as far as the eye can see, fist-sized green balls of light are floating, and the brilliant green light emitted from them completely illuminates the entire underground world.

"It's so full of life force. The whole person was bathed in that green light, Xia Mu felt extremely comfortable, and couldn't help but let out a long howl.

At this moment, Lingyao, who had entered the underground world first, had already come to the center surrounded by a green ball of light, which was a spring, divided into blue and green, and there seemed to be an invisible barrier between the two, independent of each other but constituting that spring.

"This is the Yin Yang Life and Death Divine Spring?" His eyes stared at the blue and green staring below, Xia Mu's throat couldn't help but roll, and a flash of heat flashed in his eyes.

Yin and Yang Divine Fountain, condensed in the intersection of heaven and earth Yin and Yang, after millions of years to take shape, the spring water is blue and green, blue is Yin Spring, containing endless death, and green is Yang Spring, containing endless life force, the two are one, only then can it be called Yin and Yang Life and Death Divine Spring.

At this moment, looking at the spring in front of him, Xia Mu was inexplicably a little nervous and excited, he had been waiting for this day for a long time, although the reincarnation of life and death seals in his body had been sealed by the ten great god generals, but because of the long-term contamination of death qi, countless vitality had already been consumed in the three palaces of Shentai, so he needed this Yin and Yang Life and Death Divine Spring to recuperate.

With a look of emotion, Xia Mu also stepped on his feet, and quickly swept towards the Yin and Yang Life and Death Divine Spring.

"Time is running out, you go down quickly. Seeing Xia Mu coming, Ling Yao glanced at him and reminded.

It was only at this time that Xia Mufang woke up, and then hurriedly asked, "Senior, how long is it until the Ten Thousand Realms Tower closes?"

"Less than three months. Of course, if you don't have any interest in those Heavenly Treasures of the Thirteenth Layer Heaven, three months is quite a lot for you. Ling Yao said with a smile.

Hearing this, Xia Mu didn't say a word, and jumped into the water of the Yang Spring without hesitation.

"Boom!"

As Xia Mu jumped into the water of the Yang Spring, a green light rose into the sky, piercing through the ground and appearing directly above the valley, a green light between the heavens and the earth, causing the restlessness of the world.

In the Yin and Yang Life and Death Divine Spring, there seemed to be a chaotic explosion, not only the green light in the Yang Spring, but even the water of the Yin Spring seemed to be pulled out, bursting out of a faint blue light, which was extremely gorgeous.

At this moment, Xia Mu was floating in the water of Yangquan, and the rich life force gathered, turning into wisps of green light and pouring into Xia Mu's body, pouring into the three palaces of Shentai along the tendons and acupoints in his body, moisturizing every place contaminated by death.

Xia Mu was a little surprised, is this the Yin Yang Life and Death Divine Spring? It automatically poured into his body without him deliberately absorbing it, and the huge life force was like a boundless sea, vast and profound.

Ling Yao stood by Quan Tan and watched all this, and after observing it for a while, he sent a message to Xia Mu to say goodbye and let him leave on his own afterwards, and after doing all this, Ling Yao completely disappeared from this place.

The green light was filled with blue light, and the entire underworld was completely occupied by these two lights.

"Buzz!"

In the divine spring, the majestic life force gathered from all directions, pouring into Xia Mu's body from the various acupoints of his body, brilliant and blazing, becoming the only focus of this heaven and earth.

At this moment, Xia Mu was **** all over, sitting cross-legged in the Yang Spring, his black hair was flying, his body was crystal clear, exuding bursts of soft green light, quiet and peaceful, like a jade man, constantly absorbing the life force in the Yang Spring.

In the process, wisps of black mist floated out of his Heavenly Spirit Cover, and were pulled into it by the water of the Yin Spring.

The green light was like a tide, wave after wave, constantly pouring into Xia Mu's body, among which the light was the most abundant three inches below his umbilicus, and it seemed that all the green rays had converged here, forming a small green sun.

At the same time, there was a green glow surging in every inch of skin in his body, this was not an ordinary life force, it was the essence of the Yang Spring.

The pores of his body were all stretched open under the moisture of this green light, and wisps of black mist were constantly quenched out of his body, making his flesh and bones stronger and tighter.

It didn't take long for the three palaces of Xia Mu Shentai to sound in unison, completely regaining their vitality and vitality, and the hidden dangers left by the previous reincarnation of life and death seals were completely eliminated, and they could continue to practice.

"Brush!"

With a flash of light, Xia Mu rushed out of the yang spring, surrounded by green light, like a child of life descending into the world.
