Then, his body began to emit an eerie glow that came from his heart, and they jumped around his body as if to welcome him.

In that ancient ruin, Niu Er's body was surrounded by a mysterious light, his heart beating faster, and sweat dripping from his forehead.

His breathing became rapid and powerful, as if he could feel the power of another world slowly awakening.

The surroundings become eerie and terrifying.

The branches of the trees swayed and wailed.

The silent night breeze carries a strange aura that makes people feel suffocated.

The moonlight shines through the black clouds, illuminating Niu Er's figure, outlining his silhouette with an eerie atmosphere.

Niu Er's eyes flashed with light, and he took a deep breath, and the magic weapon in his hand let out a low humming sound, as if he approved of his ritual.

His voice grew low and hoarse: "O ancient power, please listen to my call and pour your wisdom and power into me!" ”

With the sound of Niu Er's incantation, an invisible energy began to gather around his body, forming a swirling light.

The light grew brighter and brighter, more and more dazzling, as if it was about to swallow the whole world.

Niu Er felt the power coming from the ancient stone tablet, his body trembled, but he was full of determination.

A deep hole appeared in mid-air, and the dark mouth of the cave emitted a suffocating stench, as if it led to the entrance to hell.

The air around the cave entrance became heavy and filled with an evil aura that made people shudder.

Niu Er stared at the entrance of the cave tightly, and an inexplicable fear surged in his heart.

He saw that in the mouth of the cave, countless long, twisted tentacles were constantly wriggling, like the fingers of the devil, with an evil aura, quietly swaying in the darkness.

The tentacles are covered in slime and shimmer with a creepy glow.

The monster's body gradually crawled out of the hole, and Niu Er's eyes almost popped out of their sockets. It was a huge snake-like creature, dozens of meters long, and its whole body was covered with black scales, revealing a terrifying and hideous appearance.

Its head was triangular, its eyes shimmered like rubies, and its mouth bared sharp teeth that smelled of decay.

Niu Er felt a chill in his heart, and he looked at this monster, as if he saw the darkest side of his heart.

He knew that he had summoned the monster, and that he had awakened the ancient power, but he could not control its power.

The monster gradually approached Niu Er, and those tentacles got closer and closer, as if to sweep him into the dark abyss. Niu Er's heart was full of despair and helplessness, and he realized that he had made a mistake and awakened an existence that should not be awakened.

"Stop! Stop it! Niu Er shouted in despair, only to hear his own voice echoing in the empty night sky.

His spell had lost its effect, and he could no longer control the monster.

The monster's tentacles were getting closer and closer, and Niu Er felt that his body was tightly bound by an invisible force, and he couldn't move.

His breathing became rapid, and sweat continued to drip from his forehead. He understood that he was destined to fall victim to this monster.

Suddenly, a flash of inspiration flashed through Niu Er's mind.

He remembered the magic weapon in his hand, and he held it tightly, gathering the remaining strength and delivering the final blow.

The magic weapon let out a piercing buzzing sound, and a bolt of lightning erupted from the magic weapon in the cow's second-hand and slashed towards the monster.

Thunder and lightning hit the monster's body, making a loud roar.

The monster's form quickly collapsed, turning into a cloud of black smoke and dissipating into the night sky.

Niu Er breathed a sigh of relief, and he fell to the ground, covered in sweat and wheezing.

He understands that although he has defeated the monster, he has also paid a huge price.

His body and mind have been irreparably damaged.

The moonlight shone through the black clouds again, illuminating Niu Er's tired and pale face.

However, it didn't end there, and another thing crawled out of the big black hole.

Niu Er turned his head, his heart filled with endless fear and despair.

A deep hole appeared in mid-air, and the monster that emerged from it was completely different from the previous beast.

Its body was huge and dragon-like, its black scales shimmering with an evil light, exuding a suffocating aura of blood.

When this monster saw Niu Er, his eyes flashed with horror and incredulity.

Niu Er stared into the eyes of this monster, as if he saw the boundless darkness and abyss.

The monster's body was like a giant mountain, and rough black tentacles spread out from its body

The tentacles wriggled wildly, soft and terrifying, like the touch of a demon.

They are covered in slime and shimmer with a creepy glow, like an evil fire burning in the darkness.

The monster's eyes gleamed like rubies. The mouth bared sharp teeth and exuded a rotten smell, as if it were a demon from hell.

However, the monster clearly has a human face!!

This is a handsome man, and if you ignore the tentacles on his body, you may still think that he is heroic and handsome.

Niu Er felt a chill in his heart, and he couldn't take his eyes off, as if he was attracted by the fierce aura of this monster.

He understood that this monster was summoned by him, and he never expected that he not only failed to summon Tie Dan'er back, but instead summoned a monster!!

Fortunately, the black hole closed when the monster came out.

The monster gradually approached Niu Er, and those tentacles got closer and closer, as if to sweep him into the dark abyss.

Niu Er's heart was full of despair and helplessness, and he realized that he had made a mistake and awakened an existence that should not be awakened.

"Stop! Stop it! Niu Er shouted in despair, his voice echoing in the dark night sky.

However, his spell had lost its effect and he could no longer control the monster.

The monster's tentacles were getting closer and closer, and Niu Er felt that his body was tightly bound by an invisible force, and he couldn't move.

His breathing became rapid, and sweat continued to drip from his forehead.

After the monster appeared, it instantly flew onto Niu Er's back, lying on his back and gasping.

Niu Er felt a chill coming from the monster's tentacles, as if there was endless darkness and malice flowing in that tentacle.

Niu Er felt the presence of the monster in horror, and his body seemed to be bound by an invisible force, unable to break free freely.

His breathing became rapid, sweat dripping from his forehead, his heart pounding wildly in his chest, and fear swimming through his blood like a viper.

Niu Er didn't dare to move, for fear of angering this monster, and even more afraid that his resistance would lead to an even greater disaster.

He felt the presence of the monster, it was an incomparably fierce aura, like a demon born in the dark, and its existence made Niu Er's back chill.

At the same time, Niu Er's consciousness opened like a dark channel, and he could sense the monster's emotions.
