Tower Defense Strategy

At the end of September, for the first time in the same month, it arrived at the second dry cargo unit in orbit around the moon.

This is a batch of special goods-"civilization".

What is civilization? Different peoples with different customs in different regions may give different answers. The civilization sent to the moon is relatively narrow.

One is the seeds. There are 5,000 kinds of crop seeds, including wild rice, wild corn, wild potatoes not much bigger than peanuts, and artificially trained rice, wheat, and soybeans.

The weight of each seed ranges from 100 grams to ten kilograms. There are five thousand kinds of four tons in total, including seeds, containers, shelves, and protective devices. They land in front of the moon table in several containers of thirty tons in total.

Similar to the doomsday seed bank on the surface, they serve as the source of non-meat food, beverages, and early fabrics of human civilization. They not only witness the history of human civilization, but also exist as backups. They can be activated when necessary to eliminate certain generations. Genetic disease that accumulates worldwide.

Unlike the surface, icebergs or ice layers are not used to protect them in the Moon Palace. They will be pulled directly to minus 80 degrees in their respective fresh-keeping boxes.

The temperature itself is not special. The only reason is that the underground storage requires very little energy to operate at this temperature for a long time.

Too low a temperature will freeze the seeds to death, but after all, seed freezing is not at the same level as human freezing.

Human beings are too large to freeze or thaw quickly. During the process of cooling and increasing the temperature, the growth of ice crystals will cause damage to cells, which is a chronic disease of the so-called freezing of the human body.

The seeds are relatively small. This time, a set of rapid cooling devices was designed specifically for this "civilizational action" on the surface. Regardless of the size of the seeds, the entire ice-sealing process will be completed within two seconds at most.

Quick freezing can ensure that the ice crystal particles condensed by water are small enough and distributed uniformly.

Batch thawing experiments have also been conducted on the ground, which proves that the survival rate after thawing can generally reach more than 70%, and the thawing survival rate of seeds with little water can exceed 90%.

Seed survival to planting success is not a meaning, but as a reference, it can be more intuitive to understand the significance of the lunar perennial seed preservation technology.

Crop seeds, only a few varieties can be stored for thousands of years from zero to minus 20 degrees, and most of them have a shelf life of less than a hundred years, and some even only a few years.

High-speed and low-temperature freezing can extend the storage life of seeds to at least two hundred years. With a long enough storage period, only a small laboratory is needed to take out the seeds in order for planting and cultivating the next generation of seeds for storage.

The second part of "Civilization", animals.

There are two components, specimens, epidermal tissue samples and hair samples, and digital data.

Excluding humans, it covers about 20,000 species, from single-celled animals to polar bears.

Twenty thousand species obviously cannot cover all of the earth globes, and even a class of insects can only record a little.

Because the transportation from the earth to the moon is very precious, the selection criteria are very strict. The animals in it are all species that have a certain status in the history of biological evolution and civilization.

The smallest oxygen suppliers, such as green algae and cyanobacteria, without them, the earth ball is probably still a hockey puck today.

Insects such as bees, as professional creatures in the evolutionary history of plants, even now affect the global ecological chain. If the mysterious powers are used to make bees disappear overnight, human civilization will completely collapse within six years, and no pollinator such as butterflies can replace it. Its status.

Another example is the mosquito that no one likes. Regardless of whether it is admitted or not, mosquitoes are the hero of keeping the immune system active for a long time, and their status in this system is similar to that of unheated raw water. Without mosquitoes, it is difficult to imagine the extent to which human immunity will degenerate. By then, let alone alien planets, even in the space station, the sudden appearance of biological pollution may cause all people to be wiped out.

Birds that are one size larger than insects also have a larger proportion of samples.

In fact, modern human agriculture and part of the industry are based on bird poo accumulated over countless years in the earth globe. Bird poo and its fossils are the only source of phosphate fertilizer known to mankind that can be mined at a relatively low cost.

If there is no monster crisis, in addition to the freshwater crisis mentioned above, it is likely to trigger the next round of world war. It is likely to be a food crisis caused by a lack of phosphate fertilizer, because the accumulation of bird **** is not as fast as human consumption and fossil formation. The phosphate rock is far from rich, they will be exhausted before oil.

As the spirit of all things, human beings are a member of mammals and have a natural affection for furry mammals. However, in the standard of "civilized action", they still maintain restraint. The entire vertebrate subphylum Mammalia has less than one Thousands of species were selected.

Among these thousand species, various mouse samples accounted for more than 20!

In terms of blood relationship, humans and mice are very close, and the ancestors that humans can trace within the scope of mammals are also rat-shaped creatures that live in burrows.

Starting from the history of civilization, the plague brought by rats to mankind, and the related literary works that were born, are too numerous to list. The plague in West Central Continent is just that there are many deaths, not the only ones. It can be said that rats are the creatures that kill the most humans besides humans themselves... Not accurate, in fact, rats do not kill people, they are just carriers of germs.

Looking at the scientific point of view, the white mouse experiment is an introduction for students of various biology disciplines. Even a surgeon will inevitably have to perform surgery and suture on the mouse before going to the operating table. From the perspective of kinship and cost, the white rat experiment is the only acceptable starting point for the ultimate goal of the experiment directed to humans. By the way, the experimenters can also "avenge" the people who have died from the plague, and the psychological burden is relatively small.

Half of the remaining mammalian samples can be related to the history of human civilization.

Except for 20,000 specimens, the heavier ones are digital data.

Including those collected by country C itself and obtained from various partners, the mechanical hard disk machine equipment group alone is nearly 20 tons.

Including protective structure and supporting cables for data equipment, the total weight of the "civilized" animal part exceeds 80 tons.

The last is the history of civilization.

There are several specimens of skull fragments of ancient people, as well as specimens of ape-man skull fragments of the same era, and corresponding research data on the evolutionary history of humans.

A small number of hair and skin samples of modern people, no more than 500, are mostly provided by participants and candidates participating in the Future, Kunpeng, and Moon Palace projects, and a small number are samples of historical celebrities that can be collected.

Of course, the core information of this operation is also in this part-history.

As mentioned earlier, materialistic people account for a small proportion of human beings, and this is also very extreme in historical documents.

The history of civilization in Country C cannot be regarded as materialism, but it has experienced several major events in religion, and is more inclined to be practical: I am not here for psychological comfort, I am here to donate money, and you bless me to have children or get rich. Religious influence can hardly reach the ruling stratum, and country C has established a system of belief in history.

Faithful history, the chronicle is a true, credible, and untold historical record. The letter history system is not simply a history book, there are also various biographies and local chronicles to prove the authenticity of history from the side.

Faithful history can only be traced back a thousand years, and further, there will be more or less mixed history and legends.

Going forward, more than three thousand years ago, they will be more inclined to legends and myths. Although there are archaeological evidences, it is difficult to restore various details of historical events at that time because of the lack of credible written materials.

This is not the case outside of Country C.

So far, there are countries on the earth ball that use doctrines as constitutions!

In most parts of the world, the history only goes back a thousand years, and there will be legends, mythological history, and even historical materials that cannot be verified within 800 years!

But I have to say that, as mentioned earlier, the Da Qin Empire, which once ruled the East and West of the World Island separately from Country C, also has a relatively detailed record of events. Although it is inevitable that there will be taboos and beautifications, it is already the only historical data of that period and the "confidence" can be comparable to that of Country C in the same period.

Except for the history of Daqin and Country C, archaeological evidence has the highest confidence in the history of civilization a thousand years ago.

Although archaeological evidence is chronologically incontrovertible, it is irrefutable physical evidence, but it can only be used to speculate about the life culture and burial customs at that time, and it is difficult to reflect on credible historical events, unless the identity of the tomb owner and the time of entry are just right. Can match something.

This part is also the most difficult part of the "Civilization Project".

Finally, in the form of a research group, several groups submitted reports after consulting with foreign parties. Country C decided to formally use the two new indicators of "confidence" and "theological history" in historical data. They will be marked in the digital data of all documents. In the upper left corner, and will not disappear due to page turning.

"Confidence" is familiar to students who study physics. It is an indicator mainly used to observe microscopic particle phenomena.

Because applied science can’t keep up with the development of basic science, some phenomena cannot be verified or falsified with existing equipment, and they insist on claiming that they are coincidences or experimental flaws, and it is difficult for others to refute them. So there is confidence. Reproduced by experiments in different places and by different personnel, the experimental results are similar to the theoretical values ​​obtained in advance and the same results appear many times, etc., which can increase the confidence level, and vice versa.

It can be seen as a gray area between verification and falsification.

The same is true for the history of civilization data. C has a state-owned letter history system. The text has no dating. Mass archaeological evidence serves as supporting evidence. Most of the data can reach 100% confidence. A large number of data can reach 70% to 90% confidence in 3400 years.

But some, such as a certain person who separates the sea and allows people to move across the sea, cannot be said to have 100% confidence, and it is impossible to think with your feet. In the absence of circumstantial evidence such as written records, archaeological evidence, etc., its confidence is 0%, and the history of theology does not reach 100%.

The history of theology, UU reading www.uukanshu.com is a new standard based on the experience of the two largest monotheistic religions on the earth ball. Each of them has an internal chronicle. Although the gods and gods cannot be regarded as faith history, they have A large number of incidents can be confirmed with non-theological materials and personal diaries in the surrounding area, and even two rival religions can also confirm part of each other.

Therefore, reaching 100% of theological history will also produce a certain degree of confidence, and the data with zero confidence of 100% of theological history does not exist in theory.

In addition to things that have a certain degree of credibility, the pure legends and myths are also retained in the civilization history data. There are digital versions and data that can be collected. As long as the credibility is reduced to zero, they are here. Of course, there are many things that belong to a certain degree of confidence that the history of theology and mythology are mixed. If this part exists as the history of theology, it will cause additional deductions for the confidence. Due to algorithmic reasons, the minimum confidence of this kind of literature can also be maintained at 0.5%. , And will not be swept into mythological materials.

In fact, most of the work of this set of "civilization missions" had many research teams working on it before the monster crisis. At the beginning of this year, a special group was set up to coordinate the parties. In April and May, the standard calculation method for confidence and theological history was passed. It is a fully open random random inspection of authenticity, and after removing some data and samples, there are hundreds of tons of "civilization" that have arrived on the moon table today.
