Hong Shan learned that this interstellar alliance is composed of the earth, the moon, and Mars. The three planets are now inhabited and controlled by humans, and each other can pilot starships and trade freely, live, etc.

The reason why Mars became the first planet inhabited by humans is because fossils of life have been discovered in previous scientific expeditions.

Moreover, Mars's autobiographical period and axis of rotation are similar to those of Earth. Methane was discovered on Mars a long time ago, because many microorganisms on Earth, they use methane as the main exhaled gas, and Mars is not as inhospitable as originally thought. It deservedly became the first habitable planet for mankind.

The other planets in the solar system, Mercury, Venus, Jupiter, Saturn, Uranus, and Neptune, are not inhabited by humans.

Because the periphery of these planets, some are surrounded by a circle of material and cannot be broken through for the time being, such as a thick atmosphere outside Venus, which is being studied.

Some planets are resource planets and are not suitable for habitation for the time being, but they can collect resources, mine, etc. For example, Saturn, which has the most abundant water resources, is equivalent to 830 Earths, and the thickness of the water wrapped around its rock core has reached 5,000 kilometers, and this layer of water on Saturn alone has exceeded 7,000 times the total amount of water on the Earth.

Another example is the 1986 DA asteroid, which is composed mainly of iron (about 100 billion tons) and contains about 1 billion tons of gold, platinum, iridium, and other precious metals and rare earth elements.

Some planets have not yet created an environment suitable for human habitation, and are still under construction. For example, Uranus, Neptune.

In order to explore the more distant starry sky, the Interstellar Alliance has been sparing no effort in researching interstellar technology. Now it has developed a time through the past, parallel world time adjustment and transcendence. Of course, it is still in the preliminary experimental stage:

In parallel worlds, the evolution of life is 1 year: 100 years.

It means that five thousand years have passed since the ancient parallel world, and only fifty years have passed since the interstellar civilization world.

Therefore, the purpose of Traveler 1 is to travel through the past thousands of years and find an object for experimentation. It can be a person or an animal, a plant, etc. Nurture its growth, cooperate with the promotion of civilization progress, and provide real-time feedback.

And why did you choose to start from the Yu Dynasty, because the Chinese civilization of thousands of years is ancient, and the inheritance and continuation of history remain intact, which is recognized by the world.

The crossing of parallel worlds, simply put, is two parallel roads, and a car on road A can cross the fence and suddenly cross to road B.

Of course, this is only a preliminary experimental stage, and there are many risks and uncertainties. Your car on road A suddenly crosses over road B and there will definitely be a traffic accident. This requires the establishment of rules and technical conditions to circumvent it, so it is not implemented now, and research is still ongoing, which is a project that the Interstellar Alliance has been vigorously promoting.

Because the earth in the parallel world is now very advanced in high technology, but with the development of the inevitable side effects, it has caused irreplaceable damage to the soil and environment of survival, and many areas are no longer suitable for human habitation.

In addition, different countries on the planet have great differences in people's living standards due to geographical location, resources or other reasons. The Interstellar Alliance hopes to break down this barrier and build a real global village, but the reality is that it cannot be done for the time being.

Therefore, I hope to travel to the past, use the time acceleration of the parallel world, start from the basics, build a new one, just like building a house, and then move it as a whole when it is more livable.

Another point is that the world of the future is constantly developing new habitable planets. This requires a large number of human beings to inhabit and master.

The research department of the Interstellar Alliance is considering whether it is possible to collect and package the humans and resources of the parallel world in the past, and cross over when the conditions are right. Of course, the first human beings who crossed were destined to be the elites and well-known figures of that era.

This idea is very bold, and there are many practical problems involved in how to connect perfectly, but there are also possibilities for future realization.

So send Traverser No. 1 to the Yu Dynasty.

Traveler 2, went to the moon.

Traveler 3, to Mars.

"Five thousand years."

But there is a premise that after traveling through the past, in the course of 5,000 years in history, the original order cannot be disrupted. It is necessary to follow the trajectory of the original history and promote it step by step.

How to cross and merge parallel worlds after 5,000 years is the second stage of experimental research.

Because it is still in the first stage of experimentation, it is impossible to grasp. So you can't change it easily, otherwise no one knows what chaos will happen later.

One of the functions of Traverser 1 stores more than 7,000 years of civilization from the Yu Dynasty to 3800 years.

In other words, from primitive primary dynasties to interstellar science, there are various technological cultures of human beings.

There are many other technical applications in it, and Hong Shan knows very well that these need to be slowly learned, familiarized, and mastered by himself in the future. As for the other features of the Traverser One, it will be understood later. For now, let's digest the knowledge in my mind first.

Traverser 1 has not yet proposed a specific task, and it is estimated that it will give itself a period of adaptation first.

After all, my former self was just a simple little hunter, who went into the mountains to hunt with a bow and arrows every day. I am very happy to have a certain harvest, and I don't have much pursuit.

Now there are so many things in plain white, which completely disrupts normal life, and I need to slowly adjust my mentality.

While thinking wildly, I fell asleep unconsciously. After all, so much knowledge suddenly increased in my head, and it suddenly became a world encyclopedia. Hong Shan hasn't gotten used to it yet, which is very energy-consuming and brain-burning.

As a result, this awakening came the next day. Hong Shan couldn't help but smile bitterly, packed the package and came outside.

Against the snowflakes falling from the sky, Hongshan followed the mountain road and climbed to the top of Yushan. Looking into the distance, looking around, they are covered in snow.

Hongshan was deeply touched, this is the blue planet that gave birth to human civilization, and it was the first time that he found it so beautiful.

Looking back at the Yu Dynasty in which he lived, it is said that it has experienced more than 1,500 years and had fifteen emperors, but the Yu Dynasty has not left any verifiable historical records. More than 1,500 years have only been a drop in the ocean in the long river of history. At present, the tribe is still in the stage of development of half-farming and half-farming, and in the current slave society, human beings have only made simple use of iron, stone tools, and pottery, which can be regarded as the initial stage of civilization.

More than 7,000 years later, the Interstellar Alliance, human beings can already drive spaceships between the stars.

But the biggest headache for Hongshan is to see the back of the Yu Dynasty, which has experienced about 5,000 years of dynasties and hundreds of emperors.

Xia, Shang, Zhou [Western Zhou, Eastern Zhou (Spring and Autumn, Warring States)], Qin, Han (Western Han, Eastern Han), Three Kingdoms (Wei, Shu, Wu), Jin (Western Jin, Eastern Jin), Wuhu and Sixteen Kingdoms, Northern and Southern Dynasties [Southern Dynasties (Liu Song, Xiao Qi, Xiao Liang, Southern Chen), Northern Dynasties (Northern Wei, Eastern Wei, Western Wei, Northern Qi, Northern Zhou)], Sui, Tang, Five Dynasties and Ten Kingdoms [Five Dynasties (Later Liang, Later Tang, Later Jin, Later Han, Later Zhou), Ten Kingdoms (Former Shu, Later Shu, Yang Wu, Southern Tang, Wu Yue, Fujian, Ma Chu, Southern Han, Southern Ping, Northern Han)], Song (Northern Song, Southern Song) , Liao, Western Xia, Jin, Yuan, Ming, Qing.

Thinking of what Traverser One said, let yourself assist in the excavation, resource collection, and advancement of each dynasty's civilization. Even more confused, "Hey, how do you play this?" ”

Hong Shan took out the Traverser No. 1 from his arms and complained to the small metal box in his hand: "Can Lao Tzu return all these things in his mind to you?" Please go next door and ho the others. ”

Before the words fell, a lightning bolt happened to strike down in the sky, "stab," hitting the big tree on the edge of Hongshan, and a puff of black smoke came up.

"I'll go, this trick again, change to a new routine, okay, shameless future people."

Well, Hongshan children's boots are knowledgeable people in the end. This way of thinking, tone and words are also starting to be a little different from this Yu Dynasty.
