"By the way, didn't we just come in together? What went wrong?" Su Qin asked as he walked down.

"I only remember that after we came in, we didn't talk. Then we went to the room and hid separately. Finally, I was too bored, so I went to look for you, and then I realized something was wrong."

"In the end, the man stood behind me and slapped me. Fortunately, the flying sword flew out of his hand in time, returned to normal size, and forced him back."

"And after a while, I saw you coming out of the next room, followed by myself. I immediately guessed that the doll was pretending to be me."

"Then, when you were about to go down, I also panicked. I just wanted to make you realize something was wrong, so I threw the flying sword over."

Lao Wang explained why he had just confronted the man and why he had thrown the flying sword.

"Fortunately, you threw the flying sword over, so I realized something was wrong. Otherwise, if I had gone down there, there might be some trap waiting for me." Su Qin said fearfully. The doll man is indeed not very strong, but there might be someone down there.

Wait for me, it would be terrible if I didn't notice something was wrong with Doll King at that time and was plotted against me.

"That means you know how important this young master is."

"Stop blowing, be careful." The two of them walked down the stairs at the entrance of the cave and had reached the end.

I looked around and found nothing unusual.

After arriving underground, there is only a long passage, and I don't know where it leads.

There was only a faint light on both sides of the passage, and you could barely see the road clearly. Water drops dripped down from the top from time to time, making a pitter-patter sound when it hit the ground.

Su Qin took the lead and asked Lao Wang to follow carefully.

The passage was not long, and Su Qin walked to the end smoothly. After walking out of the passage, his field of vision suddenly broadened.

What appeared in front of Su Qin's eyes was an underground research room, with various bottles, jars, and equipment randomly placed on the ground.

He noticed that the equipment was still stained with blood, and it looked like it had just been used.

The research room is very large. After entering the passage, there is a hall with a passage on the left and right. Su Qin walked over and looked at each passage. There were several rooms in each passage. He opened them one by one and searched for any clues.

The doors to the room are all made of iron doors, which shine with a special luster. There are observation holes on the door, so you can see the scene inside.

The most special thing is the middle location. As soon as he entered the research room, Lao Wang's attention was attracted by a mural in the middle.

On the left side of the mural are various ghosts and monsters, all kneeling in unison towards the right side of the mural, as if they are welcoming their king.

"Hundred ghosts worship?" Lao Wang couldn't help but murmured.

The strange thing is that the object they worship is not clearly shown on the mural, just a vague back figure.

After Su Qin completed a tour of the underground research room, he returned to the lobby and said, "The rooms are all empty. I'm afraid they were moved before we came here."

"Tell me, what are they studying here? Zhu Jun was originally a human, but he was brutally tortured and turned into a ghost. Is it possible that what they are doing is to turn humans into ghosts? What is the purpose?" Lao Wang asked.

Su Qin looked at the mural in front of him and suddenly remembered the story of Xinhuo City. Are these ghosts worshiping that man?

He paused, stared at the mural, and said: "A ghost from hundreds of years ago has been wandering around until now. If you say that he has integrated into today's society, is he considered a ghost or a human?"

Lao Wang scratched his head, not understanding what Su Qin said, and wondered: "Is there a difference between ghosts and humans? Isn't the most important thing the heart? As long as he doesn't harm anyone, it doesn't matter whether it's a ghost or a human."

Su Qin sighed and said nothing more.

"Who?" Su Qin suddenly heard movement from the corner room on the right and slowly walked towards there.

With a creak, the door was opened.

Unexpectedly, a slender hand stretched out, covered with scars.

"Don't... don't hit me, I don't dare anymore." A crisp voice came from the room, sounding like the voice of a little boy.

"Come out."

"good."

After a while, a little boy of about seven or eight years old walked out of the room. He was wearing a hospital gown. The exposed parts of his body were covered with scars, many of which seemed to have been added recently.

He fidgeted with his little hands in fear and said timidly: "I...I don't dare to run anymore, don't hit me."

Su Qin did not relax his vigilance. He walked slowly to the boy's side and used his magic power to explore the little boy's body. He found that his body was very weak and did not seem to be weird.

He whispered: "What is your name and why are you here? Can you tell me?"

"My...my name is Erdan. My parents and I got lost. I kept crying under a bridge."

"Then I was so hungry and cold, and I didn't know how long it took to wake up. Until one day, an uncle said that he could feed me, give me clothes to wear, and would take me to find my parents, so I followed him.

Came here."

"They gave me something to eat, changed my clothes, and asked me to play games with them."

"But I don't want to play games anymore because the acupuncture hurts and I have to take medicine. After taking the medicine, I feel so uncomfortable that I just want to run away."

"Later, I was caught while escaping. I was beaten and locked up," the little boy said with a cry.

"It's okay, it's okay. Brother, I'll take you away and we'll talk when you get back." Su Qin stopped asking questions, not wanting Erdan to continue recalling the pain.

He held Erdan's hand and sighed. It was obvious that these people were specifically looking for people who were willing to pay the price or who were helpless to conduct experiments in order to become ghosts.

Erdan is an example of someone who was abandoned by his parents, but it's a pity that he doesn't know it yet.

Seeing Erdan's clear and transparent eyes despite being tortured, Su Qin secretly made up his mind to continue the investigation.

"Su Qin, didn't you say that there was no one in the room?" Lao Wang was a little surprised when he saw Su Qin suddenly leading a little boy out.

"Huh? That's right, I obviously didn't find anyone there just now." Su Qin hesitated for a moment, wondering if he didn't investigate carefully.

Erdan suddenly said, "Actually, I was the one who made my brother invisible to me just now."

What? The two of them were shocked.

Erdan let go of Su Qin's hand, took two steps back, and stood near the wall. He saw that Erdan's figure gradually disappeared, seeming to blend into the surrounding environment.

Lao Wang wiped his eyes, walked to where Erdan was standing, and touched Erdan's body with his hand. This meant that although it was invisible to the naked eye, physical contact could still be touched.

Even when Su Qin used his magic power, he didn't notice Erdan standing in front of him.

"Okay, come out, Erdan."

After hearing Su Qin's words, Erdan slowly showed his figure again.

Before Su Qin could ask, Erdan took the initiative to answer: "After I escaped and was caught, I felt that I had this ability. As long as I hide myself carefully, I will not be discovered."

"So when they were packing up and preparing to leave, I hid in a corner to make them think I was missing."

"Those people couldn't find me and left in a hurry. Not long after, my brother came." Erdan lowered his head and looked at his toes.

It seems that the mysterious person must have encountered some kind of trouble. Lao Wang and I don't have the strength yet to ask them to abandon the research laboratory and escape.

Su Qin thought in his heart.

"Then are there people like you here? What I mean is that they can hide themselves."

"No, it's just me."

After learning the information he wanted, Su Qin planned to go back with Lao Wang Erdan first, but it always felt weird here.

After returning from the original route, Lao Wang drove the car and the three of them returned to the tavern.

After arriving at the tavern, Su Qin asked Liu Ying to settle Erdan.

Lao Wang looked unhappy all the way. When he arrived at the tavern, he took Su Qin to the room after waiting for Su Qin to make arrangements.

As soon as the door was locked, he took out a notebook from his crotch and handed it to Su Qin.

Su Qin took it and opened it. It was filled with records of daily experiments in the underground research laboratory.

Experiment No. 1: Sia, after her boyfriend broke up with her, jumped to her death from the 18th floor. She was stimulated by drugs and could not turn into a ghost.

Experiment No. 2: Modi, whose parents were sick, was fired by his boss, was knocked to the point of paralysis by a rich second-generation drunk while crossing the road, was tortured for a week and died after using instruments, and turned into a ghost.

Experiment No. 3...Suddenly, Su Qin discovered Zhu Jun's name. Experiment No. 43: Zhu Jun, in order to take revenge on the hospital, longed for power, used new drugs and torture methods, and turned into a ghost. Unfortunately, it failed in the follow-up and should be eliminated in time.

Experiment No. 99: Erdan, an abandoned child, only stimulated by drugs, no abnormality for the time being, escaped and has been recaptured.

After I wrote about the experiment in Erdan, I stopped writing it.

It seems that this research laboratory is just to study how to turn people into ghosts. What is the purpose?

After a while, I probably won’t be able to grasp the truth.

Su Qin returned the note to Lao Wang, "When did you get it back?"

"Just when you found Erdan, I found it."

Su Qin nodded. It was right not to take it out at that time, so as not to let Erdan know about it.

He rubbed his temples and said worriedly: "One wave will come after another, so take your time."

Then he signaled Lao Wang to find a room to rest by himself, and he was going to start practicing.

Lao Wang yawned and found a room to rest, while Su Qin also silently crossed his legs and began to practice.

In the leaning tower, Mr. Liu said to himself: "I didn't expect that it is still going on. The master will not be happy, not to mention that the direction is wrong."

He stroked his beard and his eyes drifted to the wall, as if he saw the outside world through the leaning tower. He squinted slightly, as if he had made some decision, and walked up to the fourth floor of the leaning tower.

When passing the third floor, Xiuluo stood by the stairs and said coldly: "You want to go find him? Have you forgotten what the master said?"

"I dare not forget, I am here just for the master." Xiu Luo didn't stop her, folded her hands around her chest, and snorted coldly to express her dissatisfaction.

Mr. Liu quickly reached the fourth floor, but no sound was heard.

After a long time, Mr. Liu came down from the fourth floor, and Xiu Luo asked: "How?"

"He only has four words: resigned to fate."

"I knew it, forget it, the master doesn't want us to do this either." Xiuluo looked gloomy.
