Feeling Chen Xi's terrifying sword intent, Ye Feng took a playful smile, and after taking a look, his body disappeared in place.

On the west side, the air was cloudy, emitting billowing clouds that permeated the void, and even rained, and the ground was very wet.

The temperature here is very low, which has a lot to do with the yin veins, and the closer you get to the yin veins, the rich yin qi comes to your face.

Although it is pure yin qi, the aura contained in it is hundreds of times richer than that outside, which is why Tianwu Mansion was built here.

Opening the Yin Dantian, the rich yin qi around him, like a tide, poured directly into Ye Feng's body and began to nourish.

In the dantian, there were monstrous waves, forming a dragon whirlwind, sweeping the yin qi in, and it evolved into rain again, the dantian roared like the sea, and the water level was growing wildly.

"Okay, good, my immortal yuan is getting purer and purer, if you find the yang veins and form an alternation of yin and yang, it is very likely to touch the level of the five tribulation earth immortals. ”

Feeling the changes coming from his body, Ye Feng almost jumped up with joy.

Don't dare to be careless, move forward cautiously, there is a Seven Tribulation Zombie Emperor guarding here, once it is alarmed, it will be very difficult for Ye Feng to find the source of the Yin Vein.

"Knock Knock Knock ......"

There was a banging sound in front of him, and the ground began to shake, Ye Feng froze his body, looked forward, and found that it was a small group of zombie kings patrolling, there were hundreds of zombie kings, all of them five tribulations.

"This place is so tightly guarded, there must be no doubt that it is the source of the Yin vein. ”

Looking at the patrolling corpse king, Ye Feng concluded that the source of the Yin vein was here.

The further you go in, the more corpse zombie kings you will encounter, and they will gather in groups, the main purpose of which is to protect the source of the yin veins from being destroyed by humans.

Close to the Yin vein, there are many buildings built in a radius of 100 miles, different from human buildings, the buildings here are all made of stones, like fortresses.

The largest one in the middle should be the Zombie Emperor guarding here, the Seven Tribulation Demon Man, his strength is very terrifying, just now Ye Feng witnessed with his own eyes, the four Six Tribulation Peak Geniuses couldn't shake a Seven Tribulation Zombie Emperor.

If he was discovered, he would definitely have to run away and hide all his breath, Ye Feng followed the breath of the yin veins, bypassed the fortress, and approached a deeper place.

After bypassing the fortress, Ye Feng found that there was no grass here, perhaps because the yin qi was too strong, which made it extremely difficult for the creature to survive, which also caused the light here to be very dark.

This also provided Ye Feng with an excellent opportunity to hide, the radius was desolate, only the bare ground, and even could be clearly seen, the ground could also seep out of the inky black yin, this is the underground yin qi is too strong, resulting in leakage to the surface.

"Why don't you see the entrance to the Yin Vein?"

Ye Feng checked several times, but he couldn't find where the entrance of the Yin Vein was, did he have to dig up the ground here by himself?

If that's really the case, it will definitely alarm the Zombie Emperor, at least find the entrance of the Yin Vein, so that you can enter without knowing it, absorb the laws of the Yin Vein, and it is best to find the fragments of the Great Dao of the Yin Vein.

The surroundings were desolate, with only gusts of wind blowing, and the corpse king patrolling in the distance, but nothing was found.

"Xiaobai, you enter the space and see if you can find the entrance to the yin vein. ”

Ye Feng never believed that the Yin vein was here, but there was no entrance, maybe some kind of prohibition had been planted by someone, hidden in the void.

Xiao Bai turned into a meteor and burrowed directly into the void, helping Ye Feng find the entrance to the Yin Vein.

After waiting for a cup of tea, Xiaobai returned to Ye Feng's palm, which was fluffy and only the size of a fist.

"Big brother, you guessed right, the entrance of the Yin Vein was controlled by someone with a big hand, and a gate of time and space was arranged using the method of space, and it looks like this is the entrance of the Yin Vein up close, but it is not, the entrance of the Yin Vein is still a long way from here. ”

Xiao Bai told his discovery, it turned out that this was not the entrance to the Yin Vein, it was separated by the Gate of Time and Space, and if you want to enter the Land of the Yin Vein, you must first cross the Gate of Time and Space.

Even the Seven Tribulation Earth Immortals did not dare to cross the gate of time and space, once they rushed in, they could not find their way back, and they were very likely to get lost in it.

"Okay, let's go in now!"

Xiaobai understands the use of the gate of time and space, so Ye Feng is not worried, it seems that this gate of time and space is arranged by the zombie demon, but he is afraid that the people of Tianwu Mansion will come and destroy the yin veins.

In front of Ye Feng, a strange portal appeared, and Ye Feng jumped deep and disappeared in place, and soon entered the boundless darkness.

The divine sense can't be emanated, and he can't see the way back, Ye Feng was secretly surprised, this gate of time and space is too weird.

Usually reaching the Six Tribulation Earth Immortals, they can tear the void, and they can fly for a short time, and even reach the Seven Tribulation Earth Immortals, they can shuttle through space.

But space is different from the gate of time and space, which leads to another world, and if you don't get it right, you can't come back.

And the shuttle space, after all, is still in the Hailan Star Domain, but the distance is shortened, and the two cannot be confused.

"Big brother, in front of you is the entrance to the Yin vein. ”

Xiao Bai turned into a huge white holy beast, Ye Feng rode on it, carrying him towards a huge portal, this is the real entrance of the Yin Vein.

Drilling into the portal, there is a more intense yin qi in front of you, very pure, pure like a pool of immortals.

Although the yin qi was rolling, the energy contained in it was very terrifying, and across the portal, Ye Feng saw a pitch-black dragon, which was the evolution of the yin vein, slowly flowing underground.

"This yin vein has turned into a dragon shape, and it is estimated that in another 10,000 years, it will be able to turn into a yin dragon and leave this place. ”

Looking at a huge Yin Dragon entrenched in the ground, Ye Feng showed excitement, he didn't expect that this Yin Vein had been conceived into the shape of a dragon vein.

Sacrificing the Nine Hell Demon Ding, he directly devoured tens of thousands of tons of yin water, turned into pure yin qi, and integrated into the dantian, Ye Feng's immortal yuan was climbing rapidly.

"Okay, good, great, although the realm has not broken through, but my strength is increasing crazily. ”

After absorbing these yin water, Ye Feng laughed, this yin vein contained a large number of immortal elements in it, and every time the stars broke out, those immortal marks fell to the ground and were absorbed by the yin veins.

Following the Yin vein, Ye Feng wanted to find the Yin Vein fragment and refine it, so that he could comprehend the power of Yin and Yang.

Absorbing tens of thousands of tons, compared to the huge Yin veins, it was like scooping up a scoop of water in the sea.

The core of the Yin vein is the Yin Vein Fragment, which gathers the essence of the entire Yin Vein, and no matter how much Yin Water is absorbed, it cannot be worth a Great Dao Fragment.

Drilling into the icy yin water, Ye Feng wandered quickly, and the fragments of the Great Dao were estimated to be at the source of the yin veins, and only where could they find it.

At this time, the seventh layer was already in chaos, and Chen Xi's Ten Thousand Swords Dynasty Sect injured this zombie emperor and cut off one of its arms alive.

"Roar, roar, roar!"

The Zombie Emperor let out an angry roar, and the entire seventh layer shook, causing more Zombie Emperor to approach this side.

"No, let's get back!"

After Chen Xi cast the Ten Thousand Swords Dynasty Sect, his body felt a burst of emptiness, and he immediately summoned a voice and quickly fled towards the sixth layer with his companions.

None of the zombie emperors were killed, and if there was another one, I am afraid that all four small lives would be left here.

"Damn humans, stay for me!"

The Zombie Emperor's body suddenly swelled, and endless Yin Qi appeared, wrapping towards the four of them.

"Puff puff ......"

After the four of them were eroded by the yin qi, they spurted out a mouthful of inky black blood, and they were poisoned by the corpse and must be treated in time.

"You guys go quickly, I'll break off!"

Chen Xi actually wanted to stop the zombie emperor who rushed over alone, and let them escape first.

"No, let's go together!"

The four of them will never be separated, especially another man and a woman, who have an extraordinary relationship with Chen Xi, and pull Chen Xi to leave together.

Just as the four of them hesitated, another zombie emperor appeared and swooped down on the four of them.

"Hurry up, no one can walk if you don't go. ”

Chen Xi was in a hurry and asked the three of them to leave quickly.

"Don't go!"

A man and a woman gave up and left, staying where they were with Chen Xi, while He Wu's eyes hesitated, his body jumped, and he rushed towards the sixth floor, abandoning his companions.

"Damn, this He Wu is so cowardly, he chose to flee alone at this time. ”

The rest of the men let out an angry roar, the four of them have been united all the time, plus in Xifu, they are all top geniuses, but they didn't expect that He Wu would run alone.

"Forget it, in the face of life and death, his choice is right. ”

Chen Xi sighed, He Wu has always been ruthless, and choosing to flee at this time is the wisest choice, although he bears the infamy of abandoning his fellow disciples, what is more precious than death.

"Hmph, if I am allowed to escape, I will definitely not let him go. ”

The man's name is Liu Shuangshan, and the woman's name is Huang Yin, and both of them secretly swore that as long as they escaped safely, they would never let He Wu go.

Seeing the two zombie emperors rushing towards them, the three of them turned pale, thinking that this time they would definitely die, after all, one zombie emperor could be placed in their place of death, not to mention the two heads.

And at this moment, the seventh layer began to shake, and countless yin qi converged towards the same place, as if something had awakened.

"Who entered the Yin Vein!"

The Zombie Emperor let out an angry roar, and in the Yin Vein, someone actually mixed in, and also found the fragments of the Yin Vein Dao.

The two stiff emperors turned around and left, and actually gave up hunting Chen Xi and the three of them, and the three of them looked at each other, not knowing what was going on.

"Let's go!"

The three of them no longer hesitated, and immediately turned around and hurried towards the sixth floor, not leaving at this time, let alone when.

Within a few breaths, the three of them left the seventh floor, which was considered safe, and seeing He Wu smiling and grinning, he swaggered towards the top, and the rest of his life made him very happy.

"He Wu, you stop for me!"

Liu Shuangshan let out an angry roar, and He Wu, who was about to leave, choked up, turned around and looked, and found that Chen Xi and the three of them had gloomy faces, exuding a strong killing intent.

"You ...... You're not dead?"

He Wu couldn't believe it, and in the face of the pursuit of the two zombie emperors, the three of them not only did not die, but also walked out intact.

"Do you want the three of us to die in there?"

Liu Shuangshan's tone was very bad, and Huang Yin, the two of them had murderous intent, and walked towards He Wu step by step.
