The best Yin Vein is like an extremely deep Netherworld Ghost Cave, the part close to the surface is scattered with ghost energy, and the bottom is scattered with Netherworld Qi.

At the bottom of the best Yin vein, there is a small river that is dozens of miles long and meandering, and the riverside is full of Netherworld Stones, and the river flows with black water, and the river water exudes a rich Netherworld aura.

At the outlet of the river, there is a mottled stone tablet about three meters high that exudes the endless ghostly atmosphere, and the four ancient characters of "Netherworld Stone Tablet" are faintly written on the stone tablet, and the font is simple and evil. The black waters of the small river came from the edge and spread out of this Netherworld Monument.

At the end of the river, there was a bottomless crack into the ground, into which all the black water flowed. If this seam is also counted as a part of the best Yin vein, then this best Yin vein is really bottomless.

Ren Xiaoyao stood in front of the stele, looking at the four big characters of "Netherworld Stele" on the stele, and his heart couldn't calm down for a long time.

"Is this really the Underworld, or is this the Underworld? But it's not like it, the real Underworld can't be the one you enter now, and the so-called Styx is too small. Ren Xiaoyao muttered to himself in his heart.

Ren Xiaoyao stared curiously at the Styx Stone Monument for a long time, and then walked slowly along the Styx, and collected all the Netherstone stones encountered along the way into the Blue Yin Pool. Soon, the Netherstone on the edge of the River Styx, which was dozens of miles long, was all picked up by Ren Xiaoyao into the Blue Yin Pool. The water level of Biyin Lake has risen by 100 meters.

In the end, Ren Xiaoyao came to the Netherworld Stone Tablet, and the divine thought turned into a hand to grab the Netherworld Stone Tablet, wanting to put the Netherworld Stone Tablet into the Blue Yin Pool.

Suddenly, the Netherworld Stone Tablet shook, and a strange force came out of the Stone Tablet, strangling all the divine thoughts that Ren Xiaoyao threw on the Netherworld Stone Tablet. At the same time, a skeleton man wearing black armor and holding a silver Fang Tian Painting Halberd appeared from the Netherworld Stone Stele, and the Fang Tian Painting Halberd in his hand brought a black halberd-shaped hurricane, pointing directly at Ren Xiaoyao's heart.

Ren Xiaoyao was startled, his body retreated rapidly, and at the same time, the tips of the nine beast bone swords touched each other, forming a circle and slashing towards Fang Tian's halberd, and immediately turned into a spiral cone to meet the halberd-shaped hurricane.

As soon as the spiral tip cone encountered the halberd-shaped hurricane, it immediately collapsed, and the halberd-shaped hurricane only paused slightly, and continued to stab at Ren Xiaoyao.

Ren Xiaoyao's whole body shook violently, feeling the extreme power above the halberd-shaped hurricane, his face changed greatly, the mana in his body surged, and the seven bone swords instantly became one, and at the same time slashed towards the black hurricane.

"Nine Beast Soul Fire Slash, Seven Elements in One Slash!"

The seven flames slashed out from the nine bone swords combined in the air and quickly condensed into a huge sword of light, which seemed to slash towards the black hurricane slowly and urgently.

After performing the Seven Elements in One Slash, Ren Xiaoyao used the back thrust of the mana to cast the Wind Footwork under his feet, and quickly retreated ten miles away from the Netherworld Stone Monument with a mysterious body technique and extremely fast speed. After standing still, Ren Xiaoyao, who was panting wildly, immediately took out a pot of thousand-year-old spirit ru, poured it violently, and quickly replenished the mana that had just been lost. At the same time, Ren Xiaoyao took out a few more healing pills and quickly swallowed them in case of emergency.

Except for the ultimate slash that can't be performed casually, this seven-element one-in-one slash is Ren Xiaoyao's most powerful attack at the moment. Sure enough, under the attack of the Seven Elements in One Slash, the black hurricane shattered in an instant, and even the skeleton figure holding Fang Tian's painting halberd was slightly shocked and retreated a hundred meters.

"I am the ghost general of the Styx, I am ordered to guard here, wait for the mortal creatures, and leave quickly!" The skeleton man who called himself the ghost general of the Styx, after attacking Ren Xiaoyao once, did not continue to attack, but after the divine thought announced loudly, he continued to retreat into the Styx stele.

Ten miles away, Ren Xiaoyao, Tong Guò Shennian can see and hear every qiē clearly.

"The power of the blow just now is definitely stronger than the full force of the average Yuan Infant mid-stage. Moreover, the Styx ghost general doesn't seem to be using all his strength. In other words, the strength of this skeleton man, who calls himself the ghost general of the Styx, should have reached the late Yuan Infant stage. Ren Xiaoyao analyzed it like this, and immediately had the idea of retreating.

Although Ren Xiaoyao was extremely confident in his own strength, he was not confident enough to think that he could compete with the late Yuan Infant Cultivator. Moreover, this is the bottom of the best Yin Vein, and the Netherworld Qi that permeates the air has a great restriction on Ren Yao's battle.

After weighing it repeatedly, Ren Xiaoyao still decided to give up this Styx Stone Tablet with unknown effects, and not to be an enemy of the Styx Ghost General who had reached the late Yuan Infant Stage.

However, just as Ren Xiaoyao was about to leave, the bottom of the entire Superb Yin Vein vibrated violently, and the Netherworld Ghost Qi in the air quickly flowed in the same direction.

Ren Xiaoyao followed the Netherworld Ghost Qi and found that the endless Netherworld Ghost Qi in the air had all gathered on the Netherworld Stone Tablet. And the water of the River Styx in the River Styx also flowed backwards, and finally flowed into the Netherstone Tablet. The air suddenly became fresher, and there was a little more light. Ren Xiaoyao sensed slightly, and actually sensed a faint aura.

At this time, the Netherworld Stone Tablet, after sucking in all the Netherworld Qi in the air and the Netherworld Water in the Styx, actually emitted a dark nine-colored light. The Netherstone Tablet vibrated violently while emitting nine-colored light, as if some incredible force was pushing the Netherstone Tablet upwards from the ground.

The Netherworld Ghost General had already come out of the Netherworld Stone Tablet at this time, his body was upside down in the air, and the silver Fangtian Painting Halberd in his hand was against the Netherworld Stone Tablet, helping the Netherworld Stone Tablet suppress the mysterious power underground.

"Thou mortal beings, come and help me. If the Yin soldiers descend into the world, the mortal world will be in danger!" The divine thoughts of the ghost general of the Styx River hurriedly drilled into the mind of Ren Xiaoyao, who was about to retreat and run away.

Although the tone of the Styx ghost is strange, like an extremely remote ancient language, Ren Xiaoyao can still understand it. For a while, Ren Xiaoyao hesitated, not knowing whether to continue to run.

Listening to the meaning of the words of the ghost general of the Styx, there seems to be an extremely terrifying power called "Yin Soldier" pressed under the Nether Stone Tablet, once this power is born, it may destroy the entire Four Directions Realm, and may even affect other surrounding interfaces.

However, the words of the Styx ghost general have some credibility, and Ren Xiaoyao does not dare to guarantee it. Moreover, for things with unknown risks and unknown returns, the principle of letting loose is that if you can dodge, you can dodge, and if you can avoid it, you can avoid it.

It's just that if the words of the ghost general of the Styx are true, the Yin soldier is really likely to destroy the Miè realm, then it is closely related to Ren Xiaoyao, after all, Ren Xiaoyao still lives in the Quartet Realm, and is adjacent to the Quartet Realm from the business world.

"What you said is true?" Ren Xiaoyao asked as the demon eyes on his forehead opened, staring at the Netherworld Ghost General.

"What I say is true. If you help me, after this calamity, I should send you to creation!" said the ghost general in a hurry.

"Really!" Ren Xiaoyao was shocked, and he was even more uncertain about whether to help this ghost. Through the observation of the devil's eyes, Ren Xiaoyao was able to judge that what the other party said was all true.

It's just that even the ghost generals in the late Yuan Infant can't resist it, and they ask for help from Ren Xiaoyao, with Ren Xiaoyao's cultivation in the early stage of Yuan Ying, even if it is added, it is still a question whether it can prevent the Yin Soldiers from descending. If he can't stop it, Ren Xiaoyao will lose a chance to run away in advance, and maybe once the Yin soldier descends, he will become the first victim.

However, according to what the ghost general said, once the Yin Soldiers descend into the world, the entire Quartet Realm will be finished, and even if Ren Xiaoyao escapes now, he will only live for a while longer, and sooner or later he will have to face the Yin Soldiers. Rather than facing the Yin soldiers that even the Netherworld Ghost Generals in the late Yuan Infant will be afraid of in the future, it is better to stop them under the Netherworld Stone Tablet now.

"That's it, that's it, let's help him first, it's really not too late to run away, if I have to face the Yin soldiers in the end, I'd rather hide first and let those great monks worry about it. Ren Xiaoyao thought so in his heart, and finally made up his mind, and his figure flashed and rushed to the Netherworld Stone Tablet.

"Hundred ghosts drill map, out!"

Ren Xiaoyao came to the Netherworld Stone Tablet, and stretched out his hand to summon a hundred ghost drill diagrams. The Hundred Ghosts Drill Diagram flew out, quickly wrapped the Netherworld Stone, and then the four corners buckled to the ground, clinging to the ground, pressing the Netherworld Stone Tablet down. The thirty-six ghost kings who were advancing in the Hundred Ghost Drill Diagram also drilled out of the Hundred Ghost Drill Diagram at this time, pounced on the Netherworld Stone, and pressed the Netherworld Stone Tablet together.

Ren Xiaoyao drank the thousand-year-old spirit ru in a big gulp, while frantically inputting the mana into the Hundred Ghost Drill Diagram, at the same time, Ren Xiaoyao's hands kept pinching the magic trick, and the nine swords of the beast bones came out together, and the tips of the swords shot out flames of different colors, wrapped around the Netherworld Stone, and pulled the Netherworld Stone Tablet like a rope to press down.

With Ren Yao's joining, the Netherworld Stone Tablet that was slowly moving towards the ground stabilized and slowly pressed back to the ground.

At this time, Ren Xiaoyao personally felt how terrifying the power of the Netherworld Stone Tablet pushed up the ground. After the Netherstone Tablet itself has absorbed most of the thrust, the remaining small amount of thrust will be borne by Ren Yao and the Netherworld Ghost in the future. This small part of the thrust is borne by the ghost general. However, Ren Xiaoyao, who only undertook a very small part of the thrust, was still a little powerless after using ten percent of the mana in his body.

According to the previous style of doing things, he must have reservations. But he has a thousand-year-old spirit, and there is no crisis of insufficient mana, so there is no need to keep mana. Moreover, letting the ghost ghost see his strength can also serve as a wake-up call.

"If this trend continues, these so-called Yin soldiers should not be able to be born. Watching the Netherworld Stone Tablet slowly descend, Ren Xiaoyao's heart was relieved, thinking that this peerless crisis should be over. Thinking that he had unknowingly saved the Quartet Realm and even saved hundreds of other interfaces around the Quartet Realm, Ren Xiaoyao felt a sense of pride and pride in his heart for no reason.

However, Ren Xiaoyao's sense of pride and pride had just sprouted, and it was strangled in the cradle by the next scene.

Under the stone tablet of Youhe, an extremely terrifying thrust suddenly came, which made Ren Xiaoyao feel a sense of panic and powerlessness. Even if Ren Xiaoyao used the mana in his body to the extreme and exerted twelve percent of his mana, he still had the feeling of a mayfly shaking a tree.

The Netherworld Stone Monument is rising rapidly
