Gu Mingwei heard Grandma Gu ask in a soft voice, although puzzled, but nodded hastily. Grandma Gu asked again: "Do you know how to use it?"

  Gu Mingwei didn't make a sound, shook her head, and her intuition told her that something had appeared in the window that Grandma was looking at. However, her head was being held by Grandma Gu, and although it would have been easy to break free, she didn't do so. She slightly turned her head to look at Gu Mingyu on the side, only to see his face pale, with a hint of dark grey, and a tinge of deathly ash.

  "Take out the sword token, Grandma will teach you how to use it." Old Lady Gu hugged Gu Mingwei, one hand gently stroking her head. In this brief moment, she had already tied a seven-colored mysterious silk thread onto the end of Gu Mingwei's hair, and Gu Mingwei didn't notice due to her tension.

  Gu Mingwei was completely unaware, and Gu Mingyu didn't see it either. He stared intently at the windowsill, where several figures were squeezed together in the lamplight, as if peeking in. Now, the windowsill was slowly being pushed open, and from the gap that had opened up, there was no one to be seen, only endless darkness. The darkness seemed to have swallowed all the light.

  However, on the windows that had not been opened yet, several people's shadows were clearly reflected, looking as if they were lying on the windowsill, trying to look inside. Gu Mingyu's face was getting worse and worse, and her eyes seemed to be infected by the gloomy atmosphere of Balin City, becoming cold and stern. Gu Mingwei looked at his brother's expression and suddenly thought of the evil ghost's eyes for some reason. She took out the sword symbol that she had been hiding on her body, feeling suspicious in her heart. The sword symbol looked very simple, not made of gold, silk, silver or jade, but like a thin slice of soft ice, shrouded in a layer of mist. Through the faint mist, one could clearly see a small sword on the symbol paper that looked like thin ice. There was nothing special about the sword body, but just looking at it for a moment made people feel that if this sword were to fly out, it would surely shock the sky and no one could stop it.

  At least, that's how Gu Nainai felt now. She took the sword token from Gu Mingwei's hand and said softly, "This token can only be used by you, River God must have taught you how to use it, right?" Although her voice was much softer, she didn't show any signs of panic.

  Gu Mingwei thought about the scene when Chen Jing gave him the sword token, and vaguely felt that Chen Jing had indeed said something, but no matter how hard he tried, he couldn't remember it. At that time, his mind was in a mess and he couldn't hear anything.

  "Think again! Calm down and think carefully." said Grandma Gu in a low voice.

  Gu Ming slightly raised her head to look at Grandma Gu's expression, but she only wanted to turn around and see what was on the windowsill. She could clearly feel the gloomy aura behind her. Grandma Gu shook her head, stopping her action.

  "Calm down and focus on sensing the sword symbol, don't rush, just quietly concentrate your mind."

  Gu Ming's hand grasped the sword token, took a deep breath, and focused all her attention on it. As soon as she concentrated, she felt an inexplicable connection to the token, as if they were linked by blood and flesh. She only needed to move her mind, and the sword within the token could fly out to slay demons and evil spirits. When she took out the token to look at it in the past, she would also have this feeling, but she thought it was just her own illusion.

  At this time, she felt a sense of stability in her heart and heard Grandma Gu's voice saying: "Steady, steady, don't relax."

  Gu Ming's mind stabilized, the sword symbol in her hand slowly transformed into a ball of white mist, like a small white cloud floating in her palm. Inside the white mist was a small sword suspended within, its cold light intimidating.

  Old Lady Gu was overjoyed and hastily said: "That's right, don't be distracted, wherever Grandma calls, you'll cut wherever."

  Gu Mingwei didn't nod, but instead stared intently at the small white mist sword held in his palm, as if he hadn't heard anything.

  Grandma Gu took a deep breath, slowly closed her eyes, and suddenly shouted: "Mingyu..." The voice was extremely resolute.

  "Ah......" Gu Mingyu responded as if he had just woken up from a dream, but what entered his eyes was a dazzling flash of light.

  Only to see the originally dimly lit hall suddenly shine with a dazzling light, the light was like lightning, and it flashed out from Gu Ming's palm. Before Gu Ming could even finish his "ah", the light had already pierced through his forehead, and a blood arrow shot into the air.

  The "person" shadow behind the windowsill seemed to have been startled and suddenly closed with a "bang".

  "Ah..."

  Gu Ming's voice was hoarse from shouting, her hands clutching her head, as the sword light transformed into a hazy sword symbol that floated down to the ground amidst her cries.

  "How did this happen, why... grandma... brother..."

  Gu Ming crouched on the ground, as if all her strength had been exhausted in that one sword strike. She didn't dare to approach Gu Mingyu, who was lying on the ground with eyes still filled with deep terror.

  "Grandma, how could you have called out the wrong name, how could you have called out the wrong name......" Gu Mingwei didn't lift his head, both hands grasping his hair and tugging at it with force.

  Grandma Gu slowly opened her eyes, but instead of lowering her head to stroke Gu Mingwei's head, she spoke in a slow and measured tone: "I didn't make a mistake, you didn't kill Mingyu. What you killed was just an evil spirit. Mingyu had already been possessed by the evil spirit when he came back."

  Gu Ming was stunned and disbelieving, losing his voice as he muttered: "He wasn't always good..." As he spoke, he looked over at Gu Mingyu, who had fallen to the ground, only to see that Gu Mingyu's face had already turned a bluish-green color, with hints of decay.

  She was startled, her voice stopped abruptly, and she looked around at Grandma Gao in a daze. Grandma Gao continued: "Mingyu has been possessed by an evil spirit without realizing it. I have a talisman on me that can ward off evil spirits, which is why I was feeling hot when you came in. After testing you both, I confirmed that Mingyu was indeed possessed. I'm heartbroken too, but don't blame yourself, he didn't die at your hands. Now if you don't kill him, he will devour your soul when you're not paying attention."

  "Ah, ah, but he's my brother......" Gu Mingwei burst into tears again. Just then, the sound of a window opening came from outside, and Gu Mingwei, crouching on the ground in tears, didn't even hear it. A gust of cold wind blew in, bringing with it an eerie chill.

  "Xing Wei..." Grandma Guo called out softly, but Gu Xingwei just hugged her head and didn't get up at all.

  Grandma Gu just shouted once and didn't shout again, she couldn't make a sound either, because she was already shrouded in a black aura, those black auras drilled into her seven orifices, in the blink of an eye, Grandma Gu's face was already covered with a layer of grayish death. Her skin and flesh shriveled up instantly, and in an instant, it had turned into a skeleton attached to human skin. The lamp suddenly went out, and the hall was pitch black, the only light source was the seven-color silk ribbon tied to Gu Ming's hair, which emitted a faint seven-color glow, shrouding her.

  All along, Gu Mingwei had always disliked Gu Mingyu, but she never thought of killing him, after all, he was her elder cousin. However, just now, when she concentrated all her energy on the sword symbol and heard Grandma Gu shout out "Mingyu", she suddenly thought of Mingyu in her mind, the tightly drawn bowstring was released instantly, the sword symbol flew off like an arrow, and by the time she reacted, the symbol had already pierced through Gu Mingyu's skull.

  Suddenly, she felt something was wrong, lifted her head, and everything in front of her eyes was pitch black. Her heart was greatly shocked: "Niangniang..." Looking towards Gu Niangniang, all she saw was a dark figure sitting there.

  "Grandma... Grandma..." Gu Mingwei didn't hear any response, she slowly got up, feeling a chill all over her body, as if someone was watching her in the darkness. She stretched out her hand to touch Grandma Gu's face, but suddenly felt a sense of warning, as if there was a poisonous snake waiting for her hand to reach out. Her hand withdrew like it had been burned by fire, and she slowly backed away, but at the same time, she felt that something in the darkness was closing in on her.

  "Hellish evil spirit..." The four words suddenly surged up in her mind, and she couldn't help but shudder, not even daring to take a breath. Just then, she saw a faint light on the ground not far away, and upon closer inspection, it was the sword symbol that had fallen to the ground.

  She immediately took a step closer, but as she turned around, she felt that the darkness in front of her was even darker, and it seemed as if the darkness was leading to an endless abyss. The light emitted by the sword symbol on the ground was blocked by the thick darkness, making it even weaker.

  She felt the same sense of danger ahead, and her footsteps came to an abrupt halt. Looking around, there was only endless darkness, as if this place was a hellish prison, with loneliness and fear surging up in her heart.

  She closed her eyes, her chest heaving, and suddenly let out a loud cry, charging forward before tumbling to the ground with a thud. It was Gu Mingyu's corpse that had tripped her up, and she happened to fall right next to Xuanwu, clutching him tightly in her hands as she wailed: "You demons, I'll kill you all! Give me back my grandma, give me back my brother... Ah..." The sword symbol in her hand transformed into a sword amidst her cries, radiating a dazzling white light that flashed and disappeared, circling around her body before vanishing. As it passed by, there was a "zizi" sound, accompanied by the mournful wails of the damned.

  In the flash of the sword, Grandma Gu's appearance appeared in her eyes.

  "Grandma..." Gu Ming quickly walked over, reached out and touched Grandma Gu's body, and instantly it crumbled like sand, turning into a pile of gray dust.

  She cried out again and turned around, then walked away, with the sword symbol transformed into a real sword resting in her palm.

  She opened the door, and outside was the same darkness, without a single sound, not even the sound of domestic animals. The vitality was completely extinguished. She walked straight out of the Gu's residence, although everything in sight was dark, but for some reason, she felt that there were ghosts lurking everywhere, where was still a human city, it had clearly become a ghostly realm.

  Suddenly, she vaguely saw someone crouching on the ground ahead, quickly walked over, and only heard the sound of chewing food. Getting closer and closer, it was too dark to see clearly, and she couldn't help but ask: "Who are you? Why are you here?"

  As soon as she finished speaking, the person crouching on the ground seemed to be startled awake, and the chewing sound stopped abruptly. He turned his head around, but Gu Mingwei couldn't see his face clearly, yet he felt a chill run down his spine. He took a step back, while the other party let out a low growl as if he had spotted something delicious, and pounced towards Gu Mingwei at an extremely fast speed, like a wild beast.

  Gu Mingwei's heartstrings were already stretched taut, and as soon as the man jumped up, her palm-supported symbol sword flashed out. A white light streaked across the man's throat, and he fell to the ground with a thud, his head severed from his body.

  Gu Mingwei composed herself and walked closer to take a look. She saw that there was another corpse lying in the place where the man had been crouching earlier, but its flesh had been gnawed away until it was unrecognizable.

  Gu Ming's face suddenly turned pale, and she rushed to the side to vomit. She continued to vomit until her stomach was empty, then stood up without looking back, and walked straight towards the city center.
