Weird apocalypse: Spend money on ghosts and get a 10,000x return

At this time, the mysterious voice sounded again: "Very good, you have completed the steps of the test."

"It's just a dog. If it dies, it dies."

"but..."

"As the controller of the final level of the Aurora Ruins, I am used to being prepared for everything."

"There is a pill on the table right now. It is extremely poisonous. Any creature that eats it will surely die."

“But if a creature with cancer eats it, a wonderful reaction will occur, eliminating the cancer.”

The mysterious voice paused, but Tengu stretched out his claws to take the medicine without saying a word.

The medicine suddenly emitted light, piercing the Tengu's claws.

"I haven't finished speaking yet."

"In a specific sense, this medicine can save a life. According to the law of equivalent exchange, to obtain this medicine, you also need a life."

"However, since your lives are more important than this dog's, the conditions have been mitigated. You only need to permanently lose both eyes in order to receive the medicine."

The mysterious voice lowered its volume, like the whisper of a devil, which made Chu Yang and others shudder.

In other words, if you want to save the little white dog's life, you have to exchange it for glasses.

What does it mean to lose an eye in this place? It's normal to fall down if you accidentally step on empty space.

Losing an eye is equivalent to losing your life!

Chu Yang looked towards Tiangou suddenly. He wanted to see Tiangou's expression.

"Wang Wang."

The little white dog stuck out its tongue and licked the Tengu's torn paws.

"Chu Yang, ask your men to get the medicine, and I will give you 10 million ghost coins." Tiangou said.

"Get lost." Chu Yang cursed, and seeing that Tiangou still wanted to do this, he continued.

"I will never do anything to harm the lives of those who follow me or those who are evil."

Tengu's face turned ugly. When he thought about the poor little white dog dying, his heart was twitching with pain.

In a trance, I seemed to be back to those childhood days that I couldn’t bear to look back on.

Finally, he made up his mind, gently touched the little white dog's head, and said: "If I save you once, I may also be saving myself."

After saying that, Tengu made up his mind and stretched out his claws to reach for the medicine.

"Are you crazy?" Chu Yang shouted.

He didn't expect that Tengu, who had such a strong murderous intention, could actually be so kind.

"I am an orphan. Before I gained intelligence, I lived the life of a stray dog." Tengu looked dazed and spoke softly.

"Even after gaining wisdom, because of his special identity, he was bullied at the bottom of the world and wandered around the world."

"I was even bullied by a cat and a mouse for several years."

"Those dark years were my childhood. Now I'll do whatever I can to help this little white dog."

"From now on, I'm a stray dog, but he's not."

What Tengu said was very touching, but as a human being, Chu Yang couldn't be moved at all.

A dog adopting another dog?

It’s over, I need to use my brain!

However, Chu Yang could more or less understand what Tiangou said about his childhood.

Any living being will eventually be trapped by his or her childhood for the rest of his or her life.

"I don't agree. We are a whole now. If you lose your eyes, you will be useless and it will affect us." Chu Yang said seriously.

"I'm giving you face, right? I have the final say with my eyes." Tengu cursed.

Chu Yang began to get anxious. If Tiangou was determined to do this, he would definitely not be able to stop him.

What a vicious final level controller.

The first three problems wanted to kill one of them, and now the cancer problem wants to kill one of them again!

Eh?

and many more?

There were three questions before, why did it become a cancer test here?

wrong!

I didn’t think of it just now, but now that I think about it carefully, it’s so inconsistent, there must be something fishy!

"Wait, don't be in a hurry. Even if the little white dog has cancer, it hasn't broken out yet." Chu Yang said.

Tengu looked at Chu Yang in confusion, not knowing what he was doing.

After Chu Yang felt this sense of disharmony, his strongest brain burst out and he immediately grasped the most critical issue.

"Well, let me ask, the subjects of this test paper are all ordinary people, right?"

The space was silent for a while before the mysterious voice said, "Yes."

"There's a problem." Chu Yang's eyes lit up.

"What's the problem?" Xuezhan looked silly.

"This test strip has a 98% accuracy rate for positive results, but a 2% error rate!"

"Among the vast population of ordinary people, two percent of false positives were detected!"

Chu Yang became more and more emotional as he spoke. After figuring out the key to the test paper, he also figured out the intention behind the mysterious voice.

“How vicious!”

"In fact, the number of people who have cancer accounts for 0.3 percent of the general population! The number of people with cancer is far less than the number of false positives."

"The cancer population ratio is 1, and the false positive population ratio is about 6.7, which allows us to draw a conclusion."

"Even if the test is positive with an accuracy rate of 98%, the actual disease rate is far lower than 100%. It is estimated to be only around 15%!"

"If the number of false positives and cancer patients is the same, then using a 98% accuracy rate for calculations won't be a problem at all!"

Chu Yang's mouth kept talking like a machine gun.

"Wait, what are you talking about? Don't I understand?" Tengu was confused. He felt a sense of pleasure as if knowledge passed through his brain without stopping at all.

"Then let me explain it more carefully. This is just like the three questions before. It's very confusing."

"It's like the three-door problem we had earlier. After eliminating one door, there are only two left. Many people think that since there are only two doors, the probability is 1/2, but that's not the case."

“The same goes for this question.”

"Cancer accounts for about 0.3 percent of the general population, and the test strips are tested on the general population, with an error rate of 2 percent."

"This 2% is far greater than 0.3%!"

"When people with cancer go for testing, 98 percent of them get tested accurately, which is 0.29 percent."

"And the false positive rate is 2 percent, which is much higher than the true positive rate."

"The actual test result you get is most likely a false positive, meaning you don't have cancer, but the test strip shows you have cancer!"

"If the test comes back positive, the probability that you actually have cancer is only about 15 percent. That's an extremely low probability. Do you understand?"

Chu Yang said a lot more and it felt like his mouth was about to run dry.

He felt that this should also be some kind of paradox, but he had never encountered it before.

Fortunately, he is now very powerful and his brain works much faster, so he can figure it out immediately after feeling something is wrong.

Otherwise, would I really be fooled by this damn mysterious voice?

No one responded.

"Do you understand?" Chu Yang asked again.

"I don't understand, smecta." Tengu was confused.
