Chapter 231

Mei is worried about the cat killing order.

Before that, their plan went very smoothly, even too smoothly, so that he once suspected that Lester's guess was wrong. There were no aliens at all, otherwise the invaders would have dealt with them.

He imagined that the other party would inevitably take the means of using the power of the characters who have successfully invaded to put pressure on the third space foundation through the government or other forces, resulting in the division or even dissolution of the foundation, which he and several main members had long prepared for the worst. But in this way, the invaders will inevitably expose some people and strength. It is better to let them go to the table than to hide in the dark like a shadow.

Of course, the invaders may take more extreme measures, such as assassination. Mei Tuo has written his last words with Lester's signature, so that he can send another public warning to mankind like Lester in case of accidents.

But none of these things happened. On the contrary, the frequent revelations and cat killing orders on the Internet completely surprised him and disrupted the rhythm of the third space foundation.

In addition to the ongoing space box and dream guide games, their research focus at this stage originally has three directions: one is the development of gray brain virus vaccine, the second is the in-depth study of the origin of Toxoplasma gondii, and the third is the identification of human consciousness and parasitic consciousness.

In these three directions, the third is the most difficult. At present, apart from knowing that alien consciousness can induce the brain to emit the uncommon radio waves that make Toxoplasma gondii dance the death dance, there is no other discovery. Probably, a breakthrough will not be made until the space box is successfully developed; The first direction is difficult because there are too few virus samples and cases, and the research and development of virus vaccine itself is a long process; There is only the second item. Because of the prevalence of Toxoplasma gondii and the 100 year research foundation, it seems that there is the greatest hope of success.

But as soon as the cat killing order came out, it became very difficult to find a cat in the city, let alone observe and experiment in the natural state. Although other animals and humans also have a large number of Toxoplasma gondii, even more than cats, cats are the ultimate host of Toxoplasma gondii. Without cats, the most important link is missing.

Wearing white overalls and gloves, Mei Ziqing walked into the office with a black-and-white flower cat in her arms: "Professor, do you really want to keep it here?"

Mei tried to hold her pipe in her mouth, reached for the cat, put it on her lap and said, "why not? There are few cats in the street now."

"But don't you worry about infection?" Mei Ziqing said anxiously.

Mei Tui laughed and said, "I didn't worry before. Why should I worry now?" suddenly, she looked all over and said seriously, "People panic because of ignorance. You are a scientific worker. How can you have this idea? The cat is the final host. Toxoplasma gondii will not run from the final host to people for no reason. The danger of the cat is that its feces contain a large number of egg sacs. As long as it is disposed of in time, you will not lick the cat's ass. how can it be so easily infected?"

"But dogs are different. Dogs like to eat dung, and they may lick the cat's ass and then lick you, which is very likely to bring insect eggs to you. Therefore, raising dogs is more likely to be infected with Toxoplasma gondii than raising cats."

"Of course, the main way of human infection with Toxoplasma gondii is not cats or dogs, but eating raw meat. There are many intermediate hosts of Toxoplasma gondii, including cattle, sheep, chickens, ducks and dogs. People may be infected if they eat uncooked cattle and sheep meat, poultry eggs or unqualified fresh milk. Westerners like to eat fresh food. We love cooked food since ancient times, which is also that the infection of Toxoplasma gondii in China is far lower than that in the West In the general survey conducted in the early 1990s, the infection rate of Toxoplasma gondii in China was only 15%. In the past 30 years, many people's living habits have been westernized, and the situation is not optimistic. You can see from the sampling survey data a while ago, at least in cities, the infection rate of residents has exceeded 40 percent. "

Mei Ziqing said with a smile, "Professor, I know all this. I'm not worried about you!"

The cat was lying on Mei Tuo's leg, moving vigilantly and uneasily, with a little panic in her eyes.

"You see, it's scared." Mei Tui gently stroked the fur on the cat's back. The cat arched its back and turned back and meowed twice. "It can feel that its population is in crisis."

Mei Ziqing said, "can it still know things outside?"

Mei Zhuo said: "Any species can feel the racial crisis. Of course, it must be when the crisis occurs. You won't feel anything wrong if you lock yourself in your room, but if people outside are being slaughtered or there are zombies everywhere like in the movie, you can certainly feel the crisis. If the number of humans continues to decline and is below a certain value, such as 10000, then Even if you don't hear the news or see death, you will feel the loneliness caused by the scarcity of population. This loneliness is not your personal loneliness, but the loneliness of race. You must have heard a very famous saying - there are no two identical leaves in the world. "

"Yes, Leibniz's famous saying," said Mei Ziqing.

"But you may not have heard another sentence."

"What?"

"There are neither two identical leaves nor a single leaf in the world."

"What does this mean?" Mei Ziqing wondered.

Mei Tuo said with a smile: "this is a metaphor made by Professor Frank when describing the quantum state, but later many people in biology and physics made an extended interpretation of this sentence, and then deduced a very important theory - the non uniqueness of the universe."

"The non uniqueness of the universe?" Mei Ziqing said, "why haven't I heard of this theory?"

Mei Tao smiled: "Because this is strictly a philosophical point of view, not a scientific theory. It means that in this universe, nothing exists alone and only, and there must be something of the same kind that exists at the same time. There can be no one leaf, no one tree, no one person, and even the universe is not unique. Scientifically speaking, I We really haven't found two identical things yet. Even in the micro world, two identical atoms have different electron trajectories. Similarly, we haven't found anything that exists only. "

Mei Ziqing nodded and said, "I see. It shows that aliens must exist. There can't be life only on earth in the universe."

Mei Tui smiled and said, "you're right, but what I want to say is not this problem. What I want to say is that if all humans in the world die and you are the only one left, you will die. In theory, you should die at the same time when the last person other than you dies."

Mei Ziqing said vaguely, "this... Is a little incredible."

"Now you should be able to understand why there is a sense of racial crisis?" Mei tried to pick up the cat on her knee and give it to Mei Ziqing. "Discuss with Aoki to see if you can find a place to raise more cats."

The cat struggled in Mei Ziqing's hand, but Mei Ziqing seemed to understand the little guy's anxiety and anxiety.
