Her eyes scanned her surroundings, and suddenly she spotted a hidden entrance ahead. A surge of joy filled her: "There's a way out!"

The fake doctor seemed to see through her thoughts, a cold smile playing on his lips: "You're quite clever." With that, he took out a jade pendant from his pocket and handed it to Xu Yuehuai, "Open the door."

Xu Yuehuai accepted the jade pendant, knowing that it might be the only chance of survival, but also worried that it might be another trap set by the fake ghost doctor.

She could not resist and could only slowly place the jade pendant into the groove on the stone door.

With a "thud," the stone door opened, followed by a barrage of flying arrows that nearly pierced her, but luckily she dodged quickly.

"Hmph, it seems you're still too green." The fake ghost doctor sneered from the side, a hint of smugness flashing in his eyes.

Xu Yuehuai suppressed her anger and pretended to be nonchalant as she walked over to help the fake ghost doctor up, and together they stepped into the tunnel.

The air inside the tunnel was damp and musty, indicating that it hadn't been used in a long time.

Xu Yuehuai's heart was still pounding. She remained vigilant, constantly scanning her surroundings, fearing that something unexpected might happen again. The fake ghost doctor, on the other hand, appeared calm and composed, as if he knew everything about the place.

The next instant, a loud bang came from the tunnel entrance, followed by several shrill screams.

Xu Yuehuai looked back and saw flames shooting into the sky at the cave entrance. Several men in black robes were blown away by the blast wave, their fates unknown.

The fake doctor stood aside, watching coldly, a sneer in his eyes.

Xu Yuehuai secretly rejoiced, but at the same time was shocked by the ruthlessness of the fake ghost doctor.

"Just a few men in black robes, nothing to fear." The fake doctor's voice was full of disdain. "However, don't be too happy yet."

Xu Yuehuai did not answer, but silently followed behind the fake doctor.

Inside the tunnel, the air was thick with the oppressive smell of smoke and dust, along with an unmistakable stench of blood, as if every inch of space was telling the story of the terrifying explosion that had just taken place.

The fake ghost doctor coldly stared at Xu Yuehuai kneeling before him, casually tossing a bunch of various medicine bottles into his hand, "Apply medicine to this venerable one."

Xu Yuehuai deliberately lowered her voice, imitating the voices of other men, her voice trembling slightly: "But I don't know any medical skills."

Even she herself felt a bit ironic when she said those words.

The fake ghost doctor smiled knowingly, "If I tell you to apply the medicine, then you'll apply it. If you can poison me to death, then you'll have some skill."

It was as if life and death were nothing more than a game to him.

Xu Yuehuai had no choice but to bite the bullet and bend down to pick up the scattered medicine bottles.

She had no choice but to carefully treat his wounds according to the fake doctor's instructions. This time, the injury was more severe than ever before, a gruesome sight of blood and gore.

The tunnel was so quiet that only the faint clinking of medicine bottles and Xu Yuehuai's slightly clumsy movements could be heard.

The fake ghost doctor closed his eyes to rest, letting Xu Yuehuai do as he pleased. There was no sign of pain on his face, as if his body was no longer made of flesh and blood, but of steel.

Xu Yuehuai initially tried to test the other party by increasing the force, but found that the other party did not move at all, not even frowning. Her doubts and vigilance increased.

Finally, after the medicine was applied, the fake doctor slowly stood up, his posture upright, as if the serious injury he had just suffered had never happened.

He turned around and strode into the depths of the tunnel.

Xu Yuehuai followed closely behind, and with the fake ghost doctor's guidance, they passed through one hidden mechanism after another, finally arriving at a spacious underground cave.

The cave was brightly lit, a stark contrast to the darkness outside. Various rare treasures were displayed around it, as well as some medical instruments and poison bottles that Xu Yuehuai had never seen before.

Beyond her surprise, she was more inclined to speculate about the fake ghost doctor's identity. This cave was clearly meticulously crafted, concealing countless secrets, and the fake ghost doctor was undoubtedly the controller of this secret world.

"Speak, who exactly are you?" The fake ghost doctor suddenly stopped, turned around, and stared coldly into Xu Yuehuai's heart.

Xu Yuehuai spoke weakly, "I don't know either."

"Stop pretending. Do you think you can hide those murders in the mine from me?" The fake ghost doctor's voice was as cold as ice, each word seemingly squeezed out from between his teeth.

"It wasn't me!" Xu Yuehuai hurriedly protested.

The fake ghost doctor suddenly stepped forward, grabbing Xu Yuehuai's neck tightly with one hand, the force so great it seemed he wanted to snap her in two: "All those who deceived me are dead. Do you want to become one of them?"

Xu Yuehuai felt increasingly short of breath, her face turning bright red. She shook her head with all her might, "No! I really don't know who I am. I... I suddenly came to my senses."

The fake ghost doctor stared into Xu Yuehuai's eyes, as if trying to discern something. After a moment, he released his grip. Xu Yuehuai collapsed to the ground, her face flushed and panting heavily. She had truly just escaped death.

"Since that's the case, you will stay by my side and become my slave." The fake ghost doctor's voice returned to its previous calmness. "I bestow upon you the name—DumbDumb."

Xu Yuehuai looked at the fake ghost doctor in front of him and bowed, saying, "Yes, sir."

The fake ghost doctor turned and entered the inner chamber of the cave, leaving behind the words: "Prepare the meal, it must suit my taste."

After saying that, he disappeared behind the curtain, leaving Xu Yuehuai alone in the same spot.

She knew that this was both a test and an opportunity, and that she might inadvertently uncover more secrets about the fake ghost doctor.

Xu Yuehuai moved through the kitchen in the cave. The kitchen was full of ingredients and utensils, which showed that the fake ghost doctor had very high requirements for food.

She skillfully wielded the kitchen utensils, carefully selected several ingredients, and poured her heart into every cut and every spatula, not only pursuing a perfect combination of color, aroma, and taste, but also trying to incorporate a subtle, almost imperceptible, element into the dish.

Soon, a table of delicious-looking and fragrant dishes was presented on the stone table, steaming hot and filling the air with aroma.

The fake ghost doctor slowly entered, his gaze sweeping over the dishes before finally settling on the seemingly ordinary dish that concealed a hidden secret.

He parted his lips slightly, picked up a chopstick, put it in his mouth, raised his eyebrows slightly, and then revealed an unexpected look of satisfaction.

"Not bad, it's much better than the skills of those mediocre chefs."

The fake doctor's praise stirred something in Xu Yuehuai's heart. He wondered to himself, "Has my cooking skill really improved again? Or has the subtle change in the dish touched his taste buds?"

As night deepened, a servant hurried to the outside of the fake doctor's cave and gently knocked on the door with trembling hands.

"Come in," the fake ghost doctor said indifferently.

The servant pushed open the door and entered, head bowed, holding massage tools in both hands, appearing unusually nervous.

"My lord, I'm here to give you a massage."

"Hmph, your technique is like tickling me." The fake doctor's tone was full of displeasure. He suddenly opened his eyes, and his sharp gaze made the servant tremble all over. He immediately knelt down and begged for mercy.

"Fine, get out! Replace him! Daidai, come here!" The fake doctor waved his hand impatiently.
