The Mysterious Sky Sword Sect was facing a group of demons that were getting even more and more ferocious.

One side was getting more and more courageous while the other side was consuming a lot of spiritual power and gaining physical strength. The longer they dragged on, the more disadvantageous it would be for the good cultivators' side.

Although Lei Mingyuan was fighting efficiently with two demon experts, he understood the severity of the situation. He quickly issued an emergency plan.

"Disciples, listen up. Form the Heavenly Element Formation to fight the enemy. Hold on."

The Heavenly Element Formation was one of the great formations that the disciples of the Mysterious Sky Sword Sect had to learn to cultivate. It did not require formation flags and materials to set up, it only required an even number of cultivators to cast spells together to complete it. It was a simple and very practical formation. The more people who formed the formation, the stronger it would be, as long as the amount of people was an even number. The power it would unleash would also be stronger.

The disciples were already finding it difficult to defend themselves individually. At this moment, when they heard Lei Mingyuan's order, they forced their opponents to retreat. They gathered together with their injured and unconscious fellow disciples.

Ye Youji immediately divided the positions for everyone. After that, he sat down cross-legged. He placed his longsword on his lap and slowly closed his eyes.

All the disciples of the Mysterious Heavenly Sword Sect quickly returned to their positions and sat down cross-legged. Everyone surrounded Ye Youji and formed an eight-edged shape.

When all the preparations were completed, everyone chanted continuously.

"Dao can be Dao, non-regular Dao;

Name can be name, non-regular name.

Nameless, the beginning of Heaven and Earth; well-known, the Mother of all things.

Therefore, there is no desire, so as to observe its wonders, there is always desire, so as to observe its fragility.

These two are of the same name, but different names. The name is called mystery, the mystery of Heaven..."

An extremely mysterious chant sounded throughout the area, and faint white light rose from the bodies of the disciples of the Mysterious Sky Sword Sect.

Buzz!

A huge milky-white sphere of light enveloped all the disciples. Everyone felt a wave of warm energy surging into their bodies, and their originally exhausted spiritual power began to gradually recover.

The Heavenly Elemental Formation did not exert any offensive power. It only had two uses, one was to help cultivators who had exhausted too much spiritual power to recover their spiritual power and spirit, and the other was to transfer to them a rare tenacity that was difficult to break.

This was also the reason why this formation was a compulsory course for the disciples of the Mysterious Sky Sword Sect even though its level was not high. If used well, it would be more effective than a high-level formation.

And the current situation was the best time to use it!

It had to be said that all of this happened in an instant. By the time the demons reacted, the Heavenly Elemental Formation had already been cast.

"You are all a bunch of good-for-nothings. What are you all still doing in a daze? Hurry up and attack the formation!"

The demon expert holding the demon blade and another demon expert worked together to block Lei Mingyuan. At the same time, they could not help but turn around and berate their confused subordinates.

In the next moment, countless black demonic Qi rippled out. After circling for a while, they turned into strange skeleton shapes and roared towards the Heavenly Elemental Formation.

"Dao can be Dao, a name can be name..."

Mysterious and mystifying mantras rang out continuously. The protective barrier that enveloped the Mysterious Sky Sword Sect disciples became increasingly opaque. When the terrifying black Qi skeleton attacks landed on it, it was like a punch hitting cotton. Not only was there no effect at all, their attacks were even completely absorbed by the formation!

Now it was the demons' turn to be dumbfounded. Could this formation be used in such a way?

Just like that?!

The demons could worship the blood moon to recover, while the Mysterious Heavenly Sword Sect also had the Heavenly Elemental Formation to survive. The battle between the two sides was in a stalemate again.

The three figures collided fiercely in the sky, but the outcome could not be decided yet. It was just that they were restraining each other to buy enough time for their own people.

...

On the other side.

At the Great Feng Dynasty, near Green Mountain City.

As far as the eye could see, the Heaven and Earth had transformed into a blood-red world. The original Green Mountain City had been completely destroyed, turned into ashy ruins.

In the sky, a large patch of blood-red clouds suddenly appeared, and muffled thunder could be heard from the thick layer of clouds that were as red as clouds of blood.

"So there's a big guy coming out!"

Su Xing slightly narrowed his eyes. For the sake of safety, he had sent Su Yan'er and Shen Yaoling to a safer place before returning alone.

The two of them had yet to recover from the shock brought by Su Xing just now. They only felt their bodies become lighter and appeared in the sky more than ten miles away.

"Big brother, what is that big thing you are talking about?" Shen Yaoling asked after she had recovered from the shock.

As soon as she finished speaking, Su Xing's figure had disappeared from their sight almost at the same time.

"Big brother..."

Su Yan'er and Shen Yaoling exchanged a glance, and their expressions could not help but be worried.

...

Rumble!

The original Green Mountain City had been reduced to ruins, and on a high platform in the middle of the ruins, a huge scarlet sphere of blood instantly exploded.

Roar!

A strange cry rang out. It sounded like a horse, a tiger, and an elephant combined, beast-like. It contained an endless amount of evil energy.

A strange creature walked out from the ruins. Its whole body was as red as fire. As it walked forward slowly, its body grew larger and larger.

Every step it took would cause the Earth to tremble. After a dozen steps, its body had turned into a small mountain of one thousand feet.

Su Xing returned to a place not far from Green Mountain City. He did not make a move directly, but stared at the huge object in front of him curiously, as if he wanted to find some clues from the huge object.

The red light emitted from the sky became more intense. Amidst the booming sounds, the ground started to rain.

Was this rainwater?! It must be strong acid!

Su Xing lowered his head to take a look, and his face became somewhat stunned.

The raindrops actually made a sound of corrosion when they fell on the ground. Even if they fell on hard rocks or trees, they would corrode a large hole, and green smoke rose from the surrounding scenery.

Not far from the depths of the forest, a muscular black bear was wailing in pain due to the rain of blood. A moment later, its pitch-black pupils suddenly turned a rich blood-red color.

Then, as if it was fine, as if it had not been hurt at all, it quickly stood up from the ground.

"Bang, bang! Roar, roar!"

It was now demonic! The sound of a frenzied beating on the chest was accompanied by a series of fierce roars.

A deer with blood-red eyes had just revealed its head when the violent red-eyed black bear rushed forward and the bear tore it into pieces. The strange black bear bathed in blood in the bloody rain was now like a demon hunting for its prey.

It was not only here that something strange happened.

Roars and sounds of fighting could be heard from the surroundings of Green Mountain City. More and more living beings were bewitched by the blood rain, and they fell into a state of chaos in a short while.

Similar scenes happened one after another within a radius of five miles.

Su Xing had the body of a Human iImmortal, so the strange blood rain did not have much effect on him. However, he still activated the Mortal-Returning Realm out of caution.

After activating his purple demon eyes, the scene within a five-kilometer radius was instantly formed in his mind. Seeing that there were no other figures around him, especially when his two Junior Sisters were obediently waiting in the distance, Su Xing slowly let out a sigh of relief.

"This blood-colored rain can actually trigger the most primitive killing instinct in the hearts of any living soul! Fortunately, this five-kilometer radius is a remote mountain area, so there aren't many people coming and going. Otherwise, it would be really hard to counter!"

At this moment, a roar that could pierce through metal and crack rocks, filled with a ferocious aura and demonic energy, swept over like a surging tide.

Then, a huge monster walked out of the blood fog and walked toward the outskirts of Green Mountain City.
