The gloomy dungeon, like a hellish inferno, lay deep underground, shrouded in darkness. Moss climbed the walls, and water droplets slid slowly down the stone, their dripping sounds echoing in the silence, like a countdown to death. Mu Yangzi slumped against the stone wall, his body tightly bound by heavy iron chains, as thick as a child's arm, rusted and deeply embedded in his skin, from which dried, congealed blood oozed and emitted a pungent, metallic stench.

His face was like a withered parchment, deeply wrinkled as if carved by a knife and axe, each line telling a story of the vicissitudes of time and the suffering of the present. His eyes were sunken in their sockets, dull and lifeless yet stubbornly flickering with a few sparks, a reflection of his indomitable spirit. Disheveled white hair fell wildly over his shoulders, and his black robe was torn into strips, fluttering helplessly in the cold, damp dungeon, just like his shattered dignity and hope.

"Cough, cough..." Mu Yangzi's cough broke the deathly silence of the dungeon. Each cough sounded like the mournful wail of a broken bellows, strained from his cracked lips, accompanied by violent tremors. Each tremor aggravated his wounds, bringing excruciating pain. Cold sweat streamed down his forehead, instantly disappearing into his filthy beard. He knew in his heart that Wang Jing, that villain, had lost all humanity and resorted to the most cruel methods for the sake of the Spirit Serpent Poisoning Technique manual. The entire Mu family was now like fish on a chopping block, poisoned and hanging by a thread. The fate of his family, so precarious, filled him with heartache, yet he was powerless to do anything about it, like a trapped beast struggling in vain.

Inside the Mu residence, red silk fluttered, like blood-red ribbons unfurling wildly. Large red lanterns hung high, their light swaying. What should have been a joyous wedding celebration was instead shrouded in a gloomy atmosphere, with a sense of decay lurking beneath the festive surface.

Mu Wanjing sat on a carved sandalwood chair, her wedding dress dazzlingly bright. The auspicious dragon and phoenix patterns embroidered with gold and silver threads were lifelike, every stitch and thread reflecting the painstaking efforts of skilled craftsmen. The jewels on her phoenix crown were dazzling and rare treasures, making her look like a fairy descended from heaven. However, her beautiful face showed no trace of the shyness and sweetness a bride should have. Instead, it was filled with restlessness and anxiety, like a bird trapped in a cage, frantically flapping its wings.

"Wang Jing's behavior these past few days has been extremely strange. Every time we make eye contact, his gaze is always shifty, as if hiding endless secrets. When we talk, his words are evasive and incoherent, completely lacking the affection and sincerity he once had. There must be something hidden here. Could it be that he's hiding something from me?" Mu Wan frowned, biting her lower lip, and muttered to herself. She tried to send her maids to find Wang Jing and get some answers, but the usually obedient maids seemed to be controlled by a mysterious force, making excuses and avoiding her gaze, as if they were afraid of some unknown fear.

The auspicious hour for the wedding had arrived. The sun shone brightly and blindingly into the courtyard of the Mu residence. Guests, dressed in their finest attire, chatted and exchanged greetings, their blessings ringing out endlessly. On the surface, it presented an image of peace and prosperity, like a grand celebration. However, behind this facade of prosperity, undercurrents surged, and danger lurked, like a turbulent undercurrent hidden beneath a calm lake, ready to unleash a storm at any moment.

Wang Jing wore a brand-new red groom's robe, its color as fiery as fire, or like congealed blood. The exquisite gold-threaded patterns shimmered in the sunlight, showcasing luxury and nobility. He stood tall and imposing, his steps steady, yet his eyes darted around rapidly, their gaze piercing yet laced with cunning and ruthlessness, like cold stars twinkling in the night sky, coldly observing every move around him. A calculating glint flashed in his eyes, as if concealing a hidden conspiracy.

As the wedding ceremony reached its halfway point, solemn and dignified music echoed in the air, and everyone's attention was focused on the newlyweds, immersed in this sacred and beautiful moment. Just then, Wang Jing seized the opportunity as Mu Wan turned around, his figure flashing like a ghost. With lightning speed, his right hand drew a gleaming dagger from his sleeve. The dagger was incredibly sharp, its tip flashing with a deathly light, instantly pressing against Mu Wan's slender waist. His left hand, like a hard iron clamp, gripped Mu Wan's delicate neck, holding her tightly in his arms, rendering her immobile.

"Don't move! Anyone who dares to make a move, I'll make sure Mu Wanxiang dies instantly!" Wang Jing suddenly raised his head and shouted at the top of his lungs. His voice was sharp and piercing, like the cry of an owl, shattering the peaceful tranquility above the Mu residence. The guests panicked immediately. Screams and shouts mingled together, and the scene instantly descended into chaos. People ran in all directions, pushing and shoving each other. The once orderly courtyard became a mess. Tables and chairs were overturned, cups and plates were shattered, and wine and delicacies were scattered all over the ground, resembling ruins after a disaster.

Mu Wan was both shocked and furious. Her eyes widened, burning with a fierce rage that seemed capable of turning Wang Jing to ashes in an instant: "Wang Jing, you shameless scoundrel, what exactly do you intend to do? Why are you treating me like this? My Mu family has treated you well, how could you bear to do such a cruel thing?" Her voice trembled slightly with anger and fear, carrying a hint of desperate sobs. Tears welled up in her eyes, but she forcibly held them back, stubbornly refusing to let them fall. That was her last bit of pride and dignity.

Wang Jing let out a maniacal, cold laugh that echoed through the chaotic courtyard, sounding particularly jarring: "Mu Wan, don't blame me, blame your Mu family's precious secret manual. If you want to live today, obediently make your grandfather hand over the Spirit Serpent Poison Technique manual, otherwise, we'll both go to the Yellow Springs today! All of this was forced upon me by your Mu family. If you hadn't held onto that manual so tightly and refused to give it up, how could I have ended up on this dead end!" His eyes revealed a twisted madness and greed, as if a demon had completely possessed his mind, his soul had long been devoured by darkness, leaving only this mad obsession driving him recklessly toward the abyss of sin.

At that moment, deep within the dungeon, Mu Yangzi felt a sudden, sharp pain in his heart, as if gripped tightly by an invisible hand, so intense it almost suffocated him. He knew that the Mu family's impending doom had finally arrived.

Wang Jing gripped Mu Wan's neck tightly with one hand, and held a dagger to her waist with the other, roughly dragging her through the winding, gloomy tunnels, heading deeper into the dungeon. Mu Wan struggled in terror, tears welling in her eyes. Her phoenix crown was already askew, and her magnificent wedding dress was in disarray.

"Wang Jing, you demon, let me go!" Mu Wan screamed angrily, her eyes filled with despair and hatred.

Wang Jing snorted coldly: "If you behave yourself, you might be able to save your grandfather's life."

Before long, they arrived at the dungeon. The dungeon was filled with a putrid stench, and the dim torches flickered weakly, illuminating Mu Yangzi's frail yet still resolute figure.

"Grandpa!" Mu Wan cried out in grief upon seeing Mu Yangzi's miserable state.

Mu Yangzi suddenly raised his head, his eyes filled with shock and anger: "Wang Jing, you despicable villain, how could you do such a treasonous thing!"

Wang Jing laughed triumphantly: "Old man, hand over the secret manual of the Spirit Serpent Poisoning Technique, or you and your grandson will both die!" As he spoke, the dagger in his hand moved even closer to Mu Wan's skin, and a trickle of blood seeped out.

Mu Yangzi was extremely anxious, but he still tried to remain calm: "You can forget about getting the secret manual. I would rather die than let it fall into the hands of a villain like you!"

Wang Jing's eyes hardened, and he made a move to plunge the dagger into Mu Wan's body: "Are you really not afraid that I will kill her?"

Mu Yangzi closed his eyes, tears streaming down his face: "Wan'er, it's all my fault..."

Mu Wan was filled with sorrow, but she still gritted her teeth and said, "Grandpa, don't worry about me, we can't let him succeed!"

A stalemate immediately ensued in the dungeon, the tense atmosphere seemingly about to burst the small space apart, and a life-or-death struggle quietly unfolded in the dark underground.
