The world enters the age of myth

The destroyer circled the edge of the island several times.

In addition to all kinds of messy biological potions, humans have also invented all kinds of weird instruments that can measure ether value, psychic strength, etc.

As long as there is some kind of supernatural phenomenon hidden on the island, it can be easily discovered.

This powerful investigative ability is no longer what it used to be.

Unkai No. What humans fear the most is not actually monsters, but various physical disasters, such as the atmosphere suddenly turning into toxic gases, which can cause disease and death once breathed in; or the emergence of some kind of super microorganisms, which can cause death. Bacteria, viruses, etc. that even strengthened humans cannot resist.

If such a disaster really happens, with the capabilities of the Unkai, there is really no way to resist it, and we can only run away in despair.

On the contrary, the appearance of strange phenomena such as monsters is not very scary...

No matter what, with the combat power in hand, I have the confidence to fight head-on.

Now even the grassroots militias have begun to use the first generation of strengthening potions, and their strength has been greatly enhanced.

At least, the level of monsters in the White Mist Continent can no longer stop the Yunhai's exploration.

In this way, time passed slowly. Several drones made several large circles in the sky and took many photos, but no danger was found.

After that, several exploration team members wearing A-level enhanced suits and more than a dozen scientists wearing power armor carefully landed on the island.

People first examined the seawater here to test its composition.

"How is it?" Lu Yiming asked.

"Sodium ions, potassium ions, magnesium ions, etc. have been detected. The composition of the seawater here is similar to that of the Earth." The scientist replied: "No special toxicity has been detected in the seawater, and no fluctuating ether value has been detected. "

"So, the sea water should be normal."

"Oh, by the way, there are a small amount of residual traces of di-p-chlorophenyltrichloroethane... which means that the people here have mastered a certain degree of chemical manufacturing capabilities. This kind of substance does not exist in nature."

"What is this? Double pair of chlorine...what is it used for?" Shi Dayong asked curiously.

The scientist smiled and explained: "A chemical substance commonly known as DDT was widely used as a pesticide in earth civilization in the middle of the 20th century. The effect was very good. It eliminated malaria and saved at least 500 million people. It can be considered a certain contribution to human civilization.”

"However, this pesticide is no longer commonly used in our country because it has certain carcinogenicity, is not easily decomposed naturally, and is easily accumulated into the human body through biological chains. However, it may still be used in underdeveloped areas such as Africa. , this pesticide is very effective against mosquitoes and very cheap. If we replace another pesticide, underdeveloped areas cannot afford it.”

"That's it." Lu Yiming touched his gas mask.

He suddenly remembered that he had seen the news about "chemical pesticides contaminating Antarctica" when he was in elementary school. That was probably DDT.

Comparing human life safety and environmental safety, which one is more important is actually a quite complicated topic.

Many things have pros and cons, and the black-and-white way of thinking about diodes is actually unwise.

He quickly shook his head and abandoned these random thoughts.

After a while, people found some traces of plastic and some chemical fiber substances on the beach.

Plastic was invented at the beginning of the 20th century on Earth's civilization, while chemical fibers were invented at the end of the 19th century. In other words, the technological strength of the indigenous civilization here is at least higher than at these two points in time.

After carefully collecting these residues into a glass box, Lu Yiming couldn't help but sigh, what does human beings mean to the entire world? Is it a parasitic bacterial virus from above, or is it a simple environmental destroyer?

Even if humans become extinct, the traces left behind will still exist and can be easily discovered.

Another older scientist suddenly said: "We have detected another important information. The natural radiation level in the air here is relatively low, that is, the level of Co-60 is much lower than that on the earth. So we suspect that humans in this world The atomic bomb was not invented.”

"So based on the above traces, I guess that the technological level of this indigenous civilization will not exceed the technological level of the civilized 1940s, that is, on the eve of World War II."

"Now just by detecting the air, can we detect whether a nuclear bomb has exploded in this world?"

"Yes, it is true. As long as the era of civilization extinction is not too long ago, it can indeed be done."

There are fundamental differences between a world where nuclear explosions have occurred and a world where nuclear explosions have not occurred, such as the radiation background in the air.

There used to be an expensive material called "low background radiation steel" on the earth, which was mainly used to salvage sunken ships before World War II.

And because of the large-scale nuclear testing after World War II, the concentration of radionuclides floating in the air was many times higher than before World War II, and the resulting steel would contain higher background radiation.

And this background radiation will take hundreds of years to slowly disappear.

As soon as they heard that humans in this world had not invented the atomic bomb, everyone breathed a sigh of relief.

Even if supernatural science continues to advance, nuclear bombs are still the Unkai's strongest weapon. With the existence of this trump card, many things that are difficult for superpowers to accomplish can be easily solved.

"Our engineers are transforming five atomic bombs into more powerful hydrogen bombs?"

"Yes, there is an upper limit to the power of the atomic bomb, but there is no upper limit to the power of the hydrogen bomb. Plus we have talents in this area, it is not too difficult to transform it. In addition, there is also powerful crystal energy Cannons can replace these super weapons to a certain extent."

Everyone discussed carefully, looking for effective information everywhere, and captured many insect specimens and put them into glass boxes.

So what exactly are the disasters in this world?

There is nothing strange about the flora and fauna on the island.

There are also some ordinary lives.

Small animals such as insects and crabs are very active and are very regular species, and the plants do not have any variation.

"Coconut trees, there are several mature coconuts here..."

It took me half a day to circle around the island, but nothing suspicious could be found.

"It seems that we still need to go deep into the mainland to discover more information."

After reaching this conclusion, Lu Yiming couldn't help but sigh. He knew that things would not be that simple. However, being able to eliminate disasters such as soil, water, plants, and insects can be considered a small gain.

"If there is no disaster on this small island, can we live directly on this small island? It would be good to have an extra square kilometer."

"It's not as simple as you think?!"

Zhong Peng shook his head and pondered for a while, then suddenly said: "Isn't it another periodic disaster? The world is in a period of peace now? Come again?"

Lu Yiming shook his head: "It's hard to say... Anyway, it's right for us to hurry up."

The exploration team returned to the destroyer with the collected samples, and many scientists began to further sort out the samples.

Lu Yiming and others were sitting in a room, talking to the Yunhai base camp through a remote conference.

Let's sort out what we observed today.

"Good afternoon, comrades of the expedition team. Here is some important information to share with you." Ding Yuan said in the video: "Our drone penetrated 800 kilometers into the mainland, took a large number of photos, and found that this civilization was completely trapped in A state of dead silence..."

The photos show factories, farmland, forests, cities, and streets.

"No living people found in the photos! No large animals!"

The silence was terrifying.

Lu Yiming's breathing gradually slowed down and his brows wrinkled.

Ding Yuan said: "So, there must be a major disaster here. And the disaster must have affected the small islands above the ocean."

"The humans here are not fools. If living on a small island can help people survive disasters, they will definitely move to the island, right?"

"But now that this has not happened, and there is no one living on the island, either they are fools, or... you must have left behind some important information."

"That makes sense."

Everyone on the destroyer was shocked and looked at the small island outside the window. Would people die if they lived here?

So, what exactly is being missed?

Everyone is racking their brains to think about, for example, periodic disasters or other reasons.

According to current research, superpower, as a kind of psychic power, must also follow some basic laws. For example, its appearance will be accompanied by the fluctuation of "ether value". This is almost an iron law!

Without the help of "ether", superpowers cannot appear for no reason.

But no one has detected any ether value on the island at all...

After thinking about it for a long time, I really found some strange places!

"I found a very important point," an expert on the Unkai said in the video.

"We have observed many insects, plants, and a large number of fish in this world, but we have not observed small mammals and birds in this world. Does this mean something?"

"Military drones have been flying in the sky for so long, and they have never found any birds. Not just birds, but monkeys, dogs, cats on land, including humans, have disappeared."

Lu Yiming's heart suddenly moved. If there were no birds near the island, it would not be surprising.

But there are no birds in an entire continent, so there is only one reason...the birds have been wiped out!

The only thing that can accurately exterminate birds is a supernatural disaster!
