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

"I just remember that when we came in, we didn't speak, and then we went to the room and hid separately. In the end, I was so bored that I went to look for you, only to find out that something was wrong. ”

"As a result, the man stood behind me and slapped me, but fortunately, the flying sword flew out of his hand in time, changed back to its normal size, and forced him back."

"And after a while, I saw you coming out of the next room, with myself by your side, and I guessed at once that it must be a doll pretending to be me."

"Then, when you were about to go down, I panicked, and just wanted you to find out that something was wrong, so I threw the flying sword over."

Lao Wang explained why he confronted the man just now, and why he threw the flying sword.

"It's good that you threw the flying sword over, so I realized that something was wrong. Otherwise, if I go down at that time, there may be some trap waiting for me. Su Qin said fearfully, the doll man is indeed not strong, but maybe someone below is waiting for me, in case I didn't find out that there was something wrong with the doll Lao Wang at that time, it would be bad if I was plotted.

"That's the importance of knowing Ben Shao."

"Don't blow it, be careful." The two of them walked down the stairs at the entrance of the cave, and by this time they had reached the end.

After looking around, no anomalies were found.

When we got underground, there was only a long passage, and I didn't know where it went.

There was only a faint light on both sides of the passage, and the road could barely be seen, and from time to time water droplets dripped down from the top, making a crackling sound on 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, and after walking out of the passage, his vision widened.

What appeared in front of Su Qin's eyes was an underground research room, with all kinds of bottles and cans, and all kinds of instruments placed on the ground at will.

He noticed that the device 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, there is a passage on the left and right, Su Qin walked over and looked at it separately, and there are several rooms in each passage. I opened them one by one and searched for clues.

The doors of the rooms are made of iron doors with a special sheen, and there are holes in the doors for observation so that you can see the scene inside.

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

On the left side of the mural are various ghosts, kneeling to the right side of the wall, as if they were a king to greet them.

"Hundred Ghost Pilgrimage?" Lao Wang couldn't help muttering.

Strangely, the mural does not clearly depict the object of their worship, just a vague back.

After Su Qin finished turning around the underground research room, he returned to the hall, "The room is empty, I'm afraid we have already moved before we came." ”

"You say, what are they studying here? Zhu Jun was originally a human being, but he was tortured and turned into a ghost, could it be that what they did was to turn people into ghosts? What about the purpose? Lao Wang asked.

Su Qin looked at the mural in front of him, and suddenly remembered the story of Flame City in his mind, could it be that these ghosts are worshipping that man?

He paused, stared at the mural, and said: "The ghost of hundreds of years ago has been fooled around until now, and you say, integrated into the current society, is he a ghost or a human?" ”

Lao Wang scratched his head, didn't understand Su Qin's words, and wondered, "Is there a difference between ghosts and people?" Isn't the most important thing the heart? As long as he doesn't harm people, what difference does it make if he is a ghost or a human. ”

Su Qin sighed and didn't say much.

"Who?" Su Qin suddenly heard a movement in the corner room on the right, and slowly walked towards it.

With a creak, the door opened.

Unexpectedly, a small slender hand reached out, scarred on it.

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

"Get out."

"Okay."

After a while, a little boy of about seven or eight years old came out of the room, wearing a hospital gown, and the exposed parts of his body were covered with scars, many of which seemed to have just increased.

He fiddled with his little hands with some fear, and said timidly, "I... I don't dare to run anymore, don't hit me. ”

Su Qin did not let his guard down, slowly walked to the boy's side, and used his mana to probe the little boy's body, and found that his body was very weak, and it didn't seem to be strange.

He said softly: "What's your name, why are you here, can you tell my brother?" ”

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

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

"They fed me, changed into clothes, and asked me to play games with them."

"But I don't want to play games anymore, because it hurts to prick the needle, and I have to take medicine, and people are so uncomfortable after taking medicine, I want to run."

"Later, when I was running away, I was caught, and I was beaten and locked up." The little boy said with tears in his voice.

"It's okay, it's okay, my brother will take you away, and I'll talk about it when I go back." Su Qin stopped asking, not wanting Erdan to continue to remember the pain.

He took 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 lonely, to come and conduct experiments and turn into ghosts.

Erdan is an example of being abandoned by his parents, but unfortunately he doesn't know it yet.

Looking at Erdan's tortured, but still clear and transparent eyes, Su Qin secretly made up his mind to continue the investigation.

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

"Huh? yes, I didn't find anyone just now. Su Qin hesitated for a moment, whether he hadn't probed carefully.

Erdan suddenly spoke, "Actually, I just made my brother unable to see me. ”

What? The two were startled.

Erdan let go of Su Qin's hand, took two steps back, and stood near the wall, only to see that Erdan's figure gradually disappeared, and seemed to merge with the surrounding environment.

Lao Wang wiped his eyes, walked to the position where Erdan was standing, touched it with his hand, and could touch Erdan's body, which showed that it was just invisible to the naked eye, and the contact of the body could still be touched.

Including Su Qin, who used mana, did not find that Erdan was standing in front of him.

"Alright, come out, second egg."

When Erdan heard Su Qin's words, he 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 hid myself with my heart, I would not be discovered." ”

"So just when they were packing up and getting ready to leave, I sneaked into the corner and let them think I was gone."

"Those people couldn't find me, so they left in a hurry, and it didn't take long for my brother to come." Erdan lowered his head and looked at his toes.

It seems that the mysterious man must be in some trouble, and Lao Wang and I don't have that kind of strength yet, so let them abandon the research room and escape.

Su Qin thought to himself.

"Are there any people like you here? I mean hiding yourself. ”

"No, I'm the only one."

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

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

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

Lao Wang's face was not good-looking all the way, and when he arrived at the tavern, after Su Qin made arrangements, he pulled Su Qin to the room.

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

Su Qin took it and opened it to see that it was a record of the daily experiments in the underground laboratory.

Experiment 1: Xia Xia, after being broken up by her boyfriend, jumped from the eighteenth floor and died, stimulated by drugs, unable to turn into a ghost.

Experiment No. 2: Modi, whose parents were sick, was fired by his boss, and when crossing the street, he was paralyzed by the drunken second generation of the rich second generation, used a device, tortured for a week and then died, turning 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, thirst for strength, used new drugs and torture methods, and turned into a ghost, but unfortunately the follow-up failed, and it should be eliminated in time.

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

After the experiment was written, it was not written.

It seems that this research room is to study how to turn people into ghosts, so what is the purpose?

After a while, I shouldn'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 the second egg, I found it."

Su Qin nodded, it was right not to take it out at that time, so as not to be known by the second egg.

He rubbed his temples and said with some worry: "Wave after wave, take your time." ”

Then he motioned to Lao Wang to find a room to rest by himself, and he was about to start cultivating.

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

In the leaning tower, Liu Lao said to himself: "I didn't expect that it was still going on, and the master would not be happy, not to mention, the direction was wrong." ”

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

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

"I don't dare to forget, I'm just for the master." Xiuluo didn't stop it, clasped her hands around her chest, and snorted coldly to express her dissatisfaction.

Liu Lao quickly went up to the fourth floor, but no sound came out.

After a long time, Liu Lao came down from the fourth floor, and Xiuluo asked, "How?" ”

"He only has four words, and he is left to fate."

"I know, forget it, the master doesn't want us to do this." Xiuluo's expression was gloomy.

Liu Lao sighed deeply, his figure seemed to become more and more rickety, and muttered: "Providence, providence." ”
