Deep in the dark cave, the candlelight flickered, reflecting the hideous demon relief on the stone wall. A woman in a dark red robe stood in front of the altar, her scarlet eyes staring at the crystal ball suspended in the air.

She is the ruler of Shadow Valley - Blood Moon Priestess Serena.

Suddenly, a black mist appeared in the crystal ball, and Leander's message came into her mind.

"Oh?"

Serena raised her eyebrows slightly, and her red lips curled up in a cold arc.

"interesting……"

She turned slowly, her robe dragging across the ground, making a rustling sound.

"That old fox, Ryandel, actually took the initiative to send a message?"

She chuckled and tapped the crystal ball with her fingertips.

"It seems that he wants to use me to get rid of these aliens in exchange for an opportunity to be promoted?"

She didn't trust Leander, but she wouldn't take any potential threat lightly.

"Somebody come!"

She shouted coldly. Outside the cave, several black-robed believers quickly knelt on the ground.

"Master Priest!"

"Send an order immediately—"

Serena's voice was cold and authoritative.

"Expand the patrol area, mobilize all elite troops, and strengthen the defense of the valley entrance."

"in addition……"

She narrowed her eyes.

"Move the location of the sacrificial ceremony immediately."

The believers looked at each other, and one of them asked cautiously.

"Master Priest, is the enemy really so powerful? Do we need to move the ceremony location?"

Serena sneered.

"Although Leandel has ulterior motives, he will not do it without a purpose. Anyone who can be valued by the elf elders is definitely not an ordinary person."

She slowly raised her hand, and a ray of dark red energy condensed at her fingertips.

"No matter who they are... don't even think about disrupting the sacrificial ceremony."

The believers trembled all over and immediately followed the order and left.

Serena stood alone in front of the altar, her scarlet eyes reflecting the candlelight, like the eyes of a demon in the abyss.

"People from another world... Oh, I want to see what kind of waves you can stir up."

……

On the outskirts of Shadow Valley, eight figures quietly crept into the shadows. Lin Ji walked in the front, accurately avoiding the dead branches and leaves on the ground with every step, without making any sound. His consciousness spread out like water waves, taking in the surrounding scene.

“This is not right.”

Lin Ji suddenly raised his hand to signal everyone to stop, his brows furrowed.

"The number of guards is more than three times greater than what was reported in the intelligence."

Xiao Ningxue's white hair shone silver in the moonlight. She tapped her fingertips and a transparent water curtain unfolded in front of everyone, showing the distribution map of the patrolling guards ahead. Dense red dots almost covered the entire canyon entrance, most of which were stiff skeletons, but there were also more than 20 black-robed cultists exuding a powerful aura.

"These skeletons are nothing to be afraid of."

Xiao Ningxue whispered.

"But those twenty-odd believers... judging by their aura and energy fluctuations, each of them has at least the strength of a single realm foundation building."

Yun Shitian moved his shoulders, and the golden armor made a slight clash sound.

"Hey, it's a good time to stretch your muscles."

A hint of fighting spirit flashed in Feng Tian's eyes.

Lin Ji was about to start arranging tactics when Dao Yan's expression suddenly changed and his pupils suddenly contracted.

"not good!"

There was a rare rush in her voice.

"Lin Ji, according to my prediction, a large number of enemies will surround us in five seconds! We have been discovered!"

Everyone's expressions suddenly changed. Lin Ji reacted the fastest, grabbing Xiao Ningxue's hand.

"Ningxue, deploy the formation first!"

Xiao Ningxue did not hesitate at all and quickly formed seals with her hands. In an instant, countless array patterns spread out from under her feet, forming a huge array with a diameter of one kilometer. As the array patterns flowed, mist covered everything around.

But Xiao Ningxue looked puzzled. The area covered by the fog was too small and was not equal to the spiritual power she input. She didn't have time to ask any questions.

"Master Pu."

Lin Ji turned to Pu Jianxing, his voice steady and powerful.

"I leave that legendary warrior to you."

Pu Jianxing nodded slightly, and the long sword behind him made a clear sound.

"Just to my liking."

Almost at the moment when the formation was formed, countless dark red runes suddenly lit up on the rock walls on both sides of the canyon. The patrolling skeleton guards turned their heads in unison, and green flames ignited in their empty eye sockets. The black-robed cultists let out a piercing scream, and black mist rose around them, quickly rushing towards the location of the eight people.

boom!

Dozens of dark red energy beams fell from the sky, instantly passing through the fog, hitting the location where Lin Ji and others were, and piercing through the earth.

"There is indeed an ambush."

After Lin Ji moved through space and helped several people avoid the attack, he clenched his right hand, and the setting sun appeared in his hand. The fluctuations of time and space flowed on the sword.

Daoyan said quickly.

"It seems like they knew we were coming back."

"Now is not the time to pursue this."

Pu Jianxing said in a deep voice, his eyes fixed on a figure on the rock wall in the distance.

"The legend is here."

A woman in a dark red robe was seen standing in the air, her scarlet eyes particularly eye-catching in the night. In her hand was a staff inlaid with skulls, and she exuded a suffocating pressure.

"People from another world."

Her voice was as cold as ice, and her eyes looked straight at Pu Jianxing through the fog.

“Welcome to your burial place.”

As she waved her staff, thousands of black-robed believers poured out from all directions and surrounded the eight people. Even more terrifying was that the ground began to wriggle, and countless white bone arms broke out of the ground, forming an army of hundreds of thousands of skeletons in the blink of an eye.

"Everyone of the Blood Moon Sect listen up!"

Priestess Selena raised her staff, and eight bloody marks appeared above the heads of Lin Ji and others.

"See the mark clearly, kill all these invaders, and sacrifice their flesh and blood to my Lord!"

The believers shouted enthusiastically, and various magics rained down. Although they were not as strong as the priestess in seeing through the fog, it was a sure thing to attack the magic mark.

Lin Ji looked at the mark above his head and found that it could not be dispelled after trying. He realized that this thing was not aimed at individuals, but was based on the earth to mark their location.

He looked around at everyone and made a quick decision.

"Act as planned! Master Pu will deal with the priestess, and the others will fight on their own. Remember to support each other!"

"understand!"

Everyone responded in unison. Pu Jianxing rushed out first and appeared next to the priestess in an instant. He forced her to retreat thousands of meters with a sword, preventing her from affecting Lin Ji and others.

Yun Shitian's golden armor gleamed brightly in the moonlight. He laughed loudly and swung his fists. Each blow was as powerful as thunder, smashing the approaching skeletons into pieces.

"Hahaha, you came just in time!"

Feng Tian followed closely behind, with blazing flames all over his body. He put his hands together, and a flame barrier spanning a thousand meters appeared, blocking the first round of attacks.

Daoyan stood still. Her predictive ability allowed her to predict every enemy's move in advance and provide the most accurate support to her companions.

Lin Ji and Xiao Ningxue stood side by side. Xiao Ningxue's hands kept changing the spells, and the water formation bloomed on the battlefield, sometimes trapping the enemy, and sometimes boosting her own side.

Lin Ji held a long sword in his hand, and with the sword energy flying, he chopped the enemies in the area into pieces. Looking at the scene in front of him, he felt a little solemn.

When he first came to Aetherius, he did not feel any signs of being suppressed, but once the battle started, he found that all non-physical attacks that left the body would decrease exponentially in size and destructive power to the earth as the distance increased.

The sword energy that Lin Ji had on Kaiyang Star could easily cut through the mountains was suppressed here and dissipated within a thousand meters.

The good news is that the damage to the enemy will not change, and he can still exert the strength of the fourth realm foundation, simply limiting his destructive power against Aetherius.

The bad news is that the large-scale attacks that could have easily eliminated them were limited by the human wave tactics.
