The monster was huge, its eyes flashed a ferocious red light, its fangs were exposed, and its sharp claws flashed coldly in the darkness.
Mo Xi immediately protected Mu Li behind him, and Mu Feng also drew his sword in an instant, ready for battle.
The monster roared and pounced on them. Mo Xi cast a powerful spell, and a beam of light rushed towards the monster. The monster nimbly dodged and continued to attack.
Mu Feng took the opportunity to go around the monster, trying to find its weakness. However, the monster noticed his intention, turned around suddenly, and swept its tail towards him, and Mu Feng dodged hurriedly.
Mu Li was not to be outdone. She waved the staff in her hand and cast a buff spell on Mo Xi and Mu Feng.
With the close cooperation of the three, the monster gradually lost the upper hand, but it remained extremely ferocious and fought desperately.
Mo Xi saw the right moment, concentrated his strength, and delivered a fatal blow. This blow hit the monster's vital point, and the monster screamed and fell to the ground.
"It's finally solved." Mu Feng breathed a sigh of relief.
"Be careful, it's not over yet." Mo Xi said.
The monster's body began to undergo strange changes, emitting a black smoke that quickly spread and enveloped them.
"Oh no, this smoke is poisonous." Mu Li shouted.
The three of them hurriedly held their breath and tried to rush out of the smoke. Just as they were panicking, a mysterious voice sounded in the cave.
"Hahaha, you can't escape."
Mo Xi shouted loudly: "Who are you? What's the point of hiding your head and showing your tail? Come out if you dare!"
"Hmph, you will know soon." said the mysterious voice.
As the smoke grew thicker, Mo Xi and the others' vision became increasingly blurred, and their hearts were filled with anxiety and vigilance.
Suddenly, a gust of wind blew, and the smoke slowly dissipated. Before them appeared a figure in a black robe, his face hidden by a hood, making it impossible to see his features.
"Do you think you can defeat my pet easily? I just lured you here on purpose." The black-robed man's voice was icy cold.
Mo Xi sneered: "No matter what conspiracy you have, we are not afraid of you."
The black-robed figure raised his hand gently, and countless dark blue flames emerged from the surroundings, drifting towards the three people. Mu Li waved his staff, muttering something, and a pale golden shield appeared before them, blocking the flames.
"You're quite capable." The black-robed man formed seals with his hands, and the ground shook. Several vines broke out of the earth and wrapped around them. Mu Feng flashed, and with a sword he raised and fell, severing the vines.
Mo Xi seized the opportunity and rushed forward, a stream of spiritual energy transformed into a sharp blade and stabbed the black-robed man. The black-robed man dodged sideways, but he didn't expect Mo Xi to have a follow-up move. Another stream of spiritual energy hit his shoulder. The black-robed man groaned and retreated.
"I'll let you go today, but you won't be so lucky next time." The man in black robe disappeared after saying this.
The three of them looked at each other. Although they were still frightened, they were determined to get to the bottom of the matter and find out the secret of the man in black robe.
They continued to explore the cave and found a hidden stone door. Mo Xi pushed it gently, but the door didn't budge.
"This stone door may have a mechanism." Mu Feng said.
The three began to look around for clues to open the stone door, and Mu Li found a strange symbol behind a stone.
"This symbol looks like the mark of some kind of formation." Mu Li said.
Mo Xi observed it carefully and said, "Perhaps this is the key to opening the stone door."
They injected spiritual power according to the patterns of the symbols, and the stone gate slowly rose, and an old breath came to their faces.
Inside the door was a spacious secret room, surrounded by various strange instruments and books.
"These things don't look simple." Mu Feng picked up a yellowed book with obscure and difficult-to-understand words on it.
Mo Xi noticed a painting on the wall, which seemed to hide some mystery.
At this moment, a low buzzing sound suddenly came from the secret room, as if something was about to wake up.
"Be careful!" Mo Xi shouted.
The ground in the center of the secret room slowly cracked open, and a huge sarcophagus slowly rose up.
Mu Li gripped her staff nervously as the lid of the sarcophagus slowly moved. The scene inside made them gasp.
Inside the sarcophagus lay a woman with a face as pale as paper. She was dressed in gorgeous yet ancient clothing, and a faint chill emanated from her body.
"Who is she? Why is she here?" Mu Feng asked in a low voice.
Just as Mo Xi was about to get closer to check, the woman's fingers suddenly moved slightly.
Mu Li exclaimed: "She seems to be still alive!"
Mo Xi stopped in his tracks warily. At that moment, the woman slowly opened her eyes, which were surprisingly blood red. She sat up, glanced at the three of them, and a strange smile curled up at the corner of her mouth.
"You are the ones who woke me up." The woman's voice was ethereal and cold.
"Are you a human or a ghost?" Mo Xi asked.
The woman chuckled and said, "I was originally a witch of the Styx, sealed here ten thousand years ago. You have disturbed my slumber. However, since you have the fate to open the stone door, I can give you a choice. Either become my blood slave and help me return to the world; or stay here forever."
"The Styx Priestess? It is rumored that the Styx Priestess is a special existence in the Asura clan. She is influenced or protected by the power of the Styx Ancestor. She has the ability to control the power of the sea of blood and can summon the power of the Styx at will!" Mu Feng said in surprise.
"I didn't expect that after all these years, there are still people in this world who can remember me!" The Styx Witch said with a smile, "You look good, so stay and be my blood slaves!"
"You're ugly, but you have beautiful thoughts! You look so pale, I'm afraid you haven't been in sight for years!" Mu Li deliberately provoked her.
Upon hearing this, the Styx Witch's face darkened and she waved her hands, sending a powerful force towards the three people.
Mo Xi, Mu Feng, and Mu Li exchanged glances before joining forces once again. They simultaneously cast spells, working together to fend off the woman's attacks. A new battle unfolded within the secret chamber.
The three men's combined resistance prevented the Stygian Witch's attack from succeeding. Furious, she formed seals with her hands and chanted an ancient incantation. Instantly, a sea of blood surged within the chamber, and a blood-red liquid emerged from the ground, spreading towards the three.
Mo Xi's eyes glared, and he clasped his hands together. A dazzling white light emanated from his body, forming a barrier to block the blood. Mu Feng leaped up, his sword ablaze with flames, and slashed at the Stygian Witch. Mu Li swung his staff, casting runes into the sea of blood, temporarily slowing its spread.
The Styx Witch waved her long sleeves, and a huge wave of blood surged towards Mu Feng. Seeing this, Mo Xi teleported in front of Mu Feng and tried his best to dispel this wave of attacks, but he was also injured and vomited blood.
Seeing Mo Xi injured, Mu Li was extremely anxious. She suddenly remembered the record in the ancient book about the sealing of the Styx Witch and shouted, "If we find her life-defining magic weapon, we can seal her again!"
The three dodged the attacks while searching the secret room. Mu Feng spotted a strange light flickering in a hidden compartment on the wall. He fought his way through the witch's obstruction and retrieved a bone whistle. Mo Xi, despite his injuries, blew the whistle, and a golden light shot out, trapping the Stygian Witch and slowly sealing her back into the sarcophagus. The crisis was temporarily averted.
