The world enters the age of myth

Professor Huang, who was standing aside, suddenly had a guess in his mind: "Could it be that the shallow water area in the Yang River can also form a continent? Can staying on the island avoid the danger of the night?"

This is beyond the scope of human experience...

"They should have discovered our plane, right?" Shi Dayong touched his chin and said.

Lu Yiming said: "Not necessarily. Our planes fly at high altitudes and low speeds, and the noise they make is difficult for ordinary people to hear."

Anti-gravity aircraft fly at an altitude of 20,000 meters, a distance that is difficult to detect with the naked eye.

Of course, people cannot rule out that the other party has special investigation methods.

"Even if they detect it, they may mistakenly think it is some special creature. Above the Yang River, there may occasionally be some mutated life forms."

People once encountered a very large bird, with a body length of 1 kilometer. The two sides met at a distance and separated at a distance.

I also encountered large groups of fish as long as whales and harvested many delicious fish eggs. Scientists have even bred this kind of fish, but unfortunately, their growth rate is not as rapid as expected.

Lu Yiming thought of another question: "If there is a shallow water area there, and our shelter drives through it, will there be a risk of being stranded?"

If the water depth is less than 300 meters, the chassis of the shelter may hit the submarine continental shelf. This is indeed worth guarding against.

"But no matter what, it's still worth investigating? This phenomenon is too abnormal..." Professor Huang said excitedly: "No matter what, they are a civilization. Maybe, we can trade? Yes, trading information, Trading items is a good choice!”

"It does make sense." Lu Yiming also nodded cautiously. He also wanted to contact unknown civilizations and obtain more information.

Maybe these ancient civilizations picked up the garbage of advanced civilizations?

Even if ancient civilizations picked up advanced technology, they couldn't use it, so they had to sell it cheaply.

Maybe they know more?

Moreover...the other party is also heading towards the New World. Maybe, probably...what do they know?

As long as you're careful enough, there should be no problem.

Especially now that the strength of the shelter has skyrocketed again.

Li Yao asked again: "Besides this ancient fleet, what else have you discovered?"

The pilot quickly said: "After the plane passed this small island, it continued to sail forward for more than a thousand kilometers, about three thousand kilometers away from the shelter. The instrument suddenly sensed an extremely strong magnetic field. The strength of the magnetic field exceeded the safety limit, and even Electric currents formed on the surface of the aircraft."

"I had to return due to fear of losing control of the plane."

When metal cuts magnetic field lines, electric current will be generated. This is junior high school physics knowledge.

Generating electric current on the surface of an aircraft is naturally extremely dangerous, making it vulnerable to lightning strikes and even static electricity fires.

The other two pilots also said: "Yes, the closer you get to that direction, the stronger the magnetic field becomes, and there are also large dark clouds in the sky. I don't know what is there..."

"Is that so..." Li Yao thought for a while and nodded slowly: "A very safe choice. The investigation this time is very good. You can go down and rest first."

In the next two hours, the investigation team leader Li Yao carefully wrote a report and submitted it.

About ancient fleets, magnetic storm clouds, the possibility of a continent beneath the dark clouds, and more.

The news soon attracted the attention of high-level government officials.

People organized relevant teams, and after detailed discussions and demonstrations, the photographed data were compared over and over again many times.

Finally, several pilots were carefully dispatched to fly the plane for a high-altitude reconnaissance, and more information was obtained.

It was also confirmed that the strange fleet was still staying in place and had not left.

After such a busy day, the relevant contact meeting was officially held at 8 o'clock in the evening.

Ding Yuan read out the fresh investigation report in front of everyone: "Everyone, after our investigation, we found that this small island belonging to an ancient civilization is not the island as imagined, but a... large floating island. It’s an island floating on the water, and it can move!”

"The specific reason why floating islands are formed is still unknown, but it is not unexplainable. It may be caused by the accumulation of gas in plant roots or underwater peat blocks, or it may be caused by part of the lake shore breaking away from the lake shore. On our former Earth, there were similar floating islands, but they were not as big."

"So, the emergence of this floating island did not exceed our expectations."

Transforming unknown phenomena into known phenomena is a conventional scientific research method.

Lu Yiming and many scientists didn't know what to say, and were even slightly disappointed. He actually expected to come into contact with an unknown product, but it turned out to be just a floating island.

Even if people don’t know how this floating island floated, how did ancient civilization build such a large floating island...

"Taken together... the direction of movement of this large floating island happens to be the direction of the magnetic field."

"They should know some special information. About... the New World."

"According to the survey data, this unknown civilization may have possessed the scientific and technological data of the first industrial revolution, but due to its population size, it probably just picked up some rubbish from somewhere."

Lu Yiming couldn't help but sigh after listening to these things...

Did you really go back to ancient times?

The product of the first industrial revolution was the steam engine. Even if it was piled on the ground and left to be picked up by people, it would mean nothing to the Unkai. At most, the raw materials have some effect.

"This ancient civilization moved slowly with the floating island as its core. The speed of movement per hour was about 4 kilometers. The power system was unknown. They owned a total of 15 thousand-ton wooden sailing ships, each of which was about 45 meters in length. , 12 meters wide.”

"According to the weight assessment of plants, the total population is about 12,000-13,000 people, and it should not be more. The agricultural capabilities and fishing capabilities of ancient civilizations will be difficult to feed a larger population."

"Including some supernatural means, 14,000 people is the upper limit. The main food rations are corn, sweet potatoes and a small amount of rice."

A 400-hectare island is equivalent to 4 square kilometers, which is equal to 6,000 acres of land. This piece of land is not too small to say that it is big or small.

In addition, 15 wooden sailboats can also be used to grow vegetables.

But the number of people who can support it is still not high.

Ancient people did not even have chemical fertilizers or pesticides, and the quality of seeds was poor. The yield of rice per mu was only 500 kilograms. If potatoes were grown, the yield per mu might be over 1,000 kilograms. The sweet potatoes may be taller, weighing two thousand pounds.

How can it be like Yunhaihao, who can produce thousands of catties per mu casually. The yield of potatoes per mu can even reach three to four thousand kilograms. So if you really traveled back in time to ancient times, if you could choose one item to bring with you, it would be sweet potatoes... This thing has a large production capacity and is easy to grow. Once it is donated, it can make the emperor happy to death.

The reason why population estimates are inaccurate is because people don't know how many animals each other has. Meat-eating and plant-eating require completely different foods.

At the end of the sentence, Ding Yuan took a deep breath: "That's it for the basic information. Do you have any opinions?"

Everyone looked at the information on hand, and the reconnaissance plane detected only the superficial content.

The plants on the floating island are lush and green, there are some watchtowers on the edge, and there is a small group of houses in the middle, making it look like a small country.

Lu Yiming was the first to raise his hand and speak: "Based on the preliminary investigation data, this unknown civilization's war capabilities are far weaker than ours. But we cannot underestimate them just because they are ancient civilizations."

"Since the other party is moving in the same direction as ours, I think we can make contact with Level 2 safety standards."

"We should not miss this opportunity to engage."

The first-level safety standard is the contact rules when facing an extremely malicious civilization like the Nubian civilization.

Under this alert, the two sides are always ready for war. If there is any trouble, Yunhai will immediately use nuclear weapons to carry out a devastating strike!

The security standards for the second level will be slightly relaxed. The situation of the contact object is unknown. It may have good intentions or bad intentions. The military's alert may be upgraded or downgraded throughout the process.

The third level of safety standards is naturally for civilizations with higher goodwill. Both parties can have harmonious contact and conduct trade to a certain extent.

The fourth-level security standard is for the entire alliance and will conduct academic exchanges and large-scale trade of goods.

The military's security controls will also be relaxed.

These safety standards correspond to different application scenarios.

After Lu Yiming offered his advice, more people soon responded.

"Yes, I agree with Mr. Lu Yiming. We really shouldn't miss this opportunity."

"If we want to survive in Yanghe for a long time, we must have more experience in external exchanges. This ancient civilization, which does not seem to be very powerful, is indeed a good contact target."

The speaker was Liang Zhenhui from the Hope, who now holds the position of deputy captain, "Not all civilizations are malicious. For example, we once encountered a group of indigenous inhabitants in the frozen world, and they taught us a lot New knowledge.”

"Besides, it will be dark in Yanghe in three months. As long as the other party has some ability, does not hide fatal dangers, and is not brainwashed by evil gods... I still prefer to stay together for warmth."

"They shouldn't be a rookie civilization, right?"

"It doesn't look like... their mental state is quite normal. They are obviously used to the living environment of Yanghe."

"What we need to be wary of is that the other party may have a 'god' similar to Nubi. However, gods are not omnipotent. When there is a huge disparity in strength, the problem will not be too big."
