When Lu Ban woke up, he saw a strange ceiling.

"Are you awake? The operation was successful, and you are now a girl."

A voice came from the side, and Lu Ban subconsciously looked down.

Fortunately, I didn’t travel through time again.

Turning around, Lu Ban looked at the person beside the bed.

Hongye was peeling an apple. Her skills were much better than Amber's, and the apple skin was not even broken.

Lu Ban watched Hongye finish peeling an apple. Just as he was about to reach out to take it, he saw Hongye take a big bite.

“Crispy and sweet.”

She commented.

This scene seemed somewhat familiar, and Lu Ban didn't know how to comment on it for a moment.

But he soon realized one thing, that is, his cognition had recovered.

At least he saw that Hongye had no tentacles and was not a monster.

"Are there tentacles under your skirt?"

Lu Ban asked, fearing that several tentacles would suddenly emerge from under Hongye's skirt and tie him up.

"roll!"

Hongye almost raised her leg to trip Lu, but considering her skirt, she didn't do it.

"You can faint even when you go to a police station, is that okay?"

Hongye teased.

"I'm super brave."

Lu Ban answered immediately.

"Forget it, I'd better not be brave anymore. Amber is worried to death. If she is worried, it will be hard for me too."

Hongye finished eating the apple, wiped her hands with a tissue, stood up and pointed to the other side of the bed.

Lu Ban saw that Amber was lying on the other side of his bed and seemed to have fallen asleep because she was too sleepy.

"How long have I slept?"

He glanced at the bedside and didn't find his cell phone.

"Just one day and one night."

Hongye said as he reached the door of the ward.

"I'll call the doctor, ha—"

She yawned, muttered that she was very sleepy, and walked out of the ward.

Lu Ban did not wake up Amber. After waiting for a while, the doctor came with Trist, Hongye and others.

This doesn't seem to be a mental hospital, just an ordinary ward.

"How does it feel?"

The doctor examined it and asked.

"Very good."

Lu Ban replied.

Amber woke up at this time. She rubbed her sleepy eyes, looking at everyone as if she was still dazed.

Everyone looked at her kindly.

"ah?"

Amber immediately sat up straight and wiped the corners of her mouth.

"I'm not. I don't."

She argued, though no one knew what she was arguing for.

"Are you really okay?"

Trist asked, you know, the two forensic police officers haven't woken up yet, and the results of the examination are not optimistic, but Lu Ban is now full of energy, as if he had just had a long sleep.

Are mentally ill people really better able to fight those things?

He thought of the iron box that still remained in the police station.

According to Lu Ban, they covered the iron box with several layers of coverings, and finally no more accidents happened.

It was the first time that Trist had seen such a weird thing. Just one look at it could make people hallucinate and go crazy.

Of course, he didn't dare to let people do the experiment. He just waited for Lu Ban to wake up.

What made Trist feel terrified was that everything Lu Ban said seemed to be gradually coming true.

After the serial killer woke up, he fell into complete madness as if he had lost his soul. He tried to bite off his tongue to commit suicide. After being stopped, he was in extreme fear all the time, suffered a mental breakdown, and was unable to communicate.

It was as if the last bit of rationality had been squeezed out of him when he met Lu Ban.

There is no way to explain this kind of thing scientifically.

Could it be that the pollution in the foreign land that Lu Ban described is real?

Is this world fake?

Drizzt was becoming increasingly uneasy.

"No problem. It seems that even though it is the same pollution, the way it works in this world is slightly different. The pollution of the jade pendant is not as serious as I imagined."

Lu Ban looked at himself. His hands and feet were still there, and his internal organs should also be in their original positions. There was no abnormality.

His mental state is also pretty good and he has not fallen into madness.

Either the pollution on the jade pendant is very mild, or the pollution in this world manifests itself in a different way.

It's also possible that it's both.

It has been a long time since Lu Ban actually came into contact with the source of pollution that caused his sanity to drop, so it is reasonable that his sense of pollution has become dull.

The pollution that would drive ordinary people crazy was just a tickle to Lu Ban in the past, but now, it is probably enough to make Lu Ban suffer.

"Have you packed that thing?"

Lu Ban confirmed it again.

"Well, in the warehouse, several more floors were added as you said."

Drizzt replied.

"What the hell is going on? I've never heard of anything that could affect people like this. Is it radioactive or chemical contamination?"

He asked again.

Trist knew that some heavy metals were harmful to humans. If exposed to them for a long time, it would cause mania and depression.

There are also radiation sources that can cause physical damage and confusion.

Coupled with Lu Ban's suggestion that wrapping the jade pendant in an iron box can isolate it from the impact, it is hard not to think of the radiation source.

“It’s knowledge.”

Lu Ban replied.

"In foreign lands, knowledge is pollution and pollution is knowledge. The surface of the jade pendant is engraved with the appearance of an indescribable great being from foreign lands. When you know its appearance, pollution will follow."

Hongye was stunned after hearing what Lu Ban said.

What she found strange was that when Lu Ban said these words, everyone looked at him as if he was a lunatic.

But now, Amber aside, the policeman was actually listening very seriously.

Could it be that the one who went crazy was not Lu Ban, but myself?

"This is outrageous. If knowledge is pollution, then aren't we being polluted all the time when we go to school?"

Drizzt found it incredible.

"Doesn't the process of your learning have an impact on your cognition?"

Lu Ban just replied indifferently.

"The knowledge we usually learn is only superficial and does not involve the underlying laws of the world. This kind of knowledge pollution is not fatal to humans who have been subtly influenced for tens of millions of years."

"So that's why I always feel dizzy when I study math. It turns out that I've been contaminated."

Hongye couldn't help but add a sentence.

"That's not the case. Maybe you just can't learn it."

Lu Ban answered immediately.

“…”

Hongye was speechless for a moment.

"Many years ago, the businessman got this jade pendant from somewhere. Two thieves broke into his villa and stole the jade pendant. They were affected and the child at home was killed. After that, the two thieves were contaminated by the jade pendant for a long time. One of them couldn't bear it and chose to commit suicide, and the other became a serial killer until he was caught."

Lu Ban briefly summarized the situation they had.

"Indeed, this is the current situation."

Drizzt nodded.

"But the clues end here. Or, the case should end here."

He was investigating a serial murder case from the beginning. The jade pendant was not related to the case, and he could not tell the judges that the man committed the crime because of contamination.

"not yet."

Lu Ban felt that his mind became much clearer and more active after being impacted by the jade pendant. He looked at Trist.

"Since the thief was contaminated when he stole the jade from the merchant's home, why was the merchant who collected the jade not affected?"
