"I caught that guy! I'll definitely kill him!" Zhang Nan said as he gnashed his teeth, before returning to the cave.

Over ten iron cages, each with one person locked inside. Although some of them had sharp claws, some were in their thirties or forties, they all had a common characteristic, and that was that they had countless rotten places on them.

Zhang Nan and Fox Fairy walked around the cave again. In another corner, they found a few wooden boxes and jars, with some food and gold and silver inside, and inside the jar, there were actually some bugs. At a glance, these bugs were exactly the same as the maggots.

And in the other jar, there was some white liquid, exactly the same as the liquid sprinkled down from the giant eagle.

"Take all of these back home and let Fei'er study them. Perhaps she can find out what they were made of." Zhang Nan took out one jar of liquid and one can of bugs, and smashed all the other insects and liquids.

"What about the people in the cage?" Fox Fairy asked.

"I don't know how long these people have been locked up here, I'm afraid their families have already thought of them as dead, and they seem to have lost their humanity, it's impossible for them to let their families claim it, so it's better to let them go, let them live their own lives, and leave the prison." Zhang Nan said.

"You have to think this through. They don't seem to be human anymore. If you let them go, what if they go and kill someone?" Fox Fairy glanced at the person in the steel cage and was very worried about this problem.

"Can we lock them up here and wait for their deaths?" After Zhang Nan finished speaking, he walked over and opened all the iron cages.

The moment the cage was opened, the people inside quickly ran out, while Zhang Nan quickly followed. The moment they came out of the hole, the 10 over people released heart-tearing and lung-splitting screams, following that, an unbelievable scene occurred.

The bodies of more than ten people were festering at a speed visible to the naked eye. They seemed very afraid of the sunlight, screaming as they ran back into the cave. However, before they even reached the cave entrance, they had already turned into a pool of thick water, exactly like the little girl just now.

"How, how is this possible?" Zhang Nan's eyes were wide opened, his face pale from fright.

"So it turns out that they are not allowed to see the light of day." Fox Fairy's face was also filled with disbelief. More than ten people had disappeared at the same time, turning into thick water.

"I, I killed them?" Zhang Nan's head exploded, he did not expect himself to release her, and in the end cause her harm.

"No, it's not your fault, it's not your fault, you didn't kill them, it's all your fault that the Ghost Doctor, it was all their fault." Fox Fairy walked over and hugged Zhang Nan as he consoled him.

"No, it's all me, it's all me …" Zhang Nan shook her head as tears rolled down her cheeks.

"Zhang Lang, I really don't blame you. I don't blame you. You let them go out of kindness. You didn't know they couldn't face the light, you didn't know anything." Fox Fairy comforted Zhang Nan.

Zhang Nan cried his heart out. He had always been thinking about how to save her, but he never thought that in the end, he would be the one to kill her.

"That's not your fault. It's not your fault. We buried them, killed that Ghost Doctor, avenged them, and avenged them, okay?" Fox Fairy consoled Zhang Nan as he walked to the side and started digging.

Over ten people had dug a huge hole, but there was no corpse to bury. In the end, they could only find a sword in the water to bury their pants.

"Don't worry, I'll definitely catch that Ghost Doctor and take revenge for all of you." Zhang Nan kowtowed three times in front of the grave, paid his respects, and then returned to Fu Zhou City.

By the time he returned to the city, it was already dusk. Seeing Zhang Nan returning, Pu Feier immediately ran over: "Where did you guys go? Why did you only return now? "

Only after he asked, did Pu Feier realize that something was wrong with Zhang Nan's emotions. He kept his head down, his face covered with dirt, his eyes red and swollen, as though he had been crying.

"What's wrong?" Song Yang walked over and asked.

"We found those two murderers. One of them was killed, and the other one escaped with his giant eagle. Finally, we found these two things. Fei'er, take a look." With that said, Fox Fairy handed the two cans over to Pu Feier.

Pu Feier opened the first jar, inside was the white liquid. She frowned: "That's right, this is the liquid."

She opened the second jar, which was filled with maggots. "Why is it so disgusting, full of bugs?"

"These worms were fed by humans. We destroyed the murderer's nest, so the things in these two jars are very important, so we brought them back for you to see." As Fox Fairy spoke, he glanced at Zhang Nan and sighed helplessly.

"Is it fed by humans?" Pu Feier squinted his eyes, and ordered someone to find a piece of pork, and put a maggot on it.

The maggots had just landed on the meat when a large piece of meat began to fester, turning into thick water in the blink of an eye.

Seeing this, Zhang Nan and Fox Fairy immediately understood.

"Damn it, they actually used people for experiments?" Zhang Nan punched onto the pillar, and with a bang, Zhang Nan created a huge pit in the pillar.

Seeing this, Zhu Liu was startled, he never thought that Zhang Nan had such power.

Even Constable Chen was secretly surprised. Such a weak and scholarly person was actually this powerful.

"What do you mean? Using people for experiments? " Song Yang asked in confusion.

"The culprit is a man called the Ghost Doctor. There was also a Volcano who colluded with him and we killed them. At that time, the Ghost Doctor rode the giant eagle and escaped. "Later on, we found more than ten cages in the cave. There were more than ten people locked in …"

Following that, Fox Fairy told them everything that happened in the cave.

"Damn it!" Hearing Fox Fairy's words, Song Yang also punched the pillar, and with another huge explosion, another huge hole appeared on the pillar.

"No wonder this white liquid is so corrosive. When it comes into contact with humans, it immediately began to fester, and then died a violent death. So they used humans to conduct experiments and fed these maggots to living people." Pu Feier said, and clenched his fists.

"Even if we use living people to feed maggots, this liquid is extremely corrosive. Once a person is exposed to it, they wouldn't die immediately. It's just that their body would be festering." Zhu Liu grabbed Pu Feier's fist, afraid that she would also punch the pillar. Zhang Nan and Song Yang had the power, but Pu Feier was just a weak woman, she did not have such a strong power.

This is their viciousness. They first used living people to feed these terrifying worms, and then used them to create a corrosive liquid, and this white liquid was also infused with a highly toxic poison. Just imagine, the white liquid corroded a person's body, and the venom followed the corroded wound and entered the body. Pu Feier said.

"This method of being inferior to animals is simply outrageous. If I catch that Ghost Doctor, I must cut her into ten thousand pieces or else I cannot avenge the citizens of this city that are suffering."
