In the vast universe, there are countless planets. Earth is just one of many planets. She is different from most planets, and life was born on this planet. However, in the vastness of the universe, it is impossible for life to exist only on Earth.

Human beings are definitely not the only ones in the universe. It's like many civilizations have visited the earth for thousands of years. At that time, the earth may still be in a primitive state, or there may have been simple life. These civilizations from the depths of the starry sky may have stayed on Earth for a very short time, but they must have left their own footprints on Earth. There are even civilizations that have inhabited the earth for some time. The Yaai are an alien civilization that has been on Earth for thousands of years.

The Yaai people came from the depths of the starry sky that the earthlings could not reach, and when they came to the earth, the earthlings were still in a very backward period. Due to some interstellar laws, the Yaai people are hidden on the earth, and they use this place as a backup land for themselves, trying to occupy this beautiful planet and solve the survival problem of their own people when they need it one day.

As the lurking Yaai people stayed on Earth for a longer time, they found the footprints of many other civilizations, proving that there were many civilizations that had come to Earth. Some even preceded them by tens of thousands of years. During the time they existed on Earth, there were also extraterrestrial civilizations that came to Earth. It's just that these other civilizations are quickly gone.

The first task of interstellar exploration is of course not to look for other civilizations. Their first task is to find a planet that is suitable for their survival or has the resources they need to plan for their future. Many advanced civilizations will occupy a planet that is suitable for their survival as soon as they find it. Even if there is already intelligent life on that planet, they will forcibly occupy it. Even if that planet has entered the list of the Star Alliance, they will rely on their strong strength to resist the punishment from the Star Alliance.

Those civilizations that came to the earth earlier than the Yaai or later than the Yaai came to the earth for the purpose of finding a land suitable for their own survival. Earth, is a very good choice. But they all stayed for a while and then left.

The Yaai people do not understand why some civilizations have far surpassed the Yaai people, but they have not forcibly occupied the earth. Do they feel that this is not the place for them to live? Or did they not even think about occupying it? Or are they afraid of the Star Alliance? Due to the limited strength of the Yaai people, although they really wanted to make this planet their own, they did not dare to do so, because in the Interstellar Alliance, the name of the earth was known for a long time. The Yaai cannot resist the punishment from the Interstellar Alliance.

With the passage of time, the Yaai people who remained on the earth gradually began to understand the human beings on the earth. They are not much different from the other races in the universe. You have to go through all kinds of hardships before you can grow up. No matter how severe the disaster, humanity has survived, and civilization has developed better. Especially in the last two hundred years, human civilization has advanced by leaps and bounds, and there is a vague meaning of stepping into interstellar navigation.

In the interstellar world that the Yaai people can reach, there is a large-scale interstellar war. This war involved several higher civilizations. Even the Interstellar Alliance could not stop this war. The Yaai have a limited level of civilization and cannot participate in this war, and at the same time they do not want to participate in this war. But the planet they live on has become a springboard for a higher civilization.

Almost overnight, the originally peaceful and peaceful Yaai Xing was hit by the Destruction Clan. In just one night, the Yaai civilization, which was much higher than the human civilization on the earth, was completely destroyed in its defenses. A large number of Yaai people died, and the remnants of the forces had to wage guerrilla warfare, hoping to hold on to their homeland. At the same time, the Yaai high-level also began to prepare for the interstellar migration of the entire race. They already knew their fate, and giving up the place where the Yaai people originated was already their only choice.

At an incalculable cost, the Yaai finally broke out of the enemy's blockade. They looked at the planet Yaai that had disappeared into the starry sky, and all the Yaai knew that they would never have a chance to go back.

Retrieving the warships and resources hidden there from several resource stars, they embark on a path to find a new home. At this time, the earth, which is far away from the war zone and even away from the sight of the Interstellar Alliance, has become the best target for the Yaai people. That is, when the Yaai people could not decide whether to risk occupying the earth for their own survival, a virus crisis broke out on the earth that almost destroyed the entire human race. The Yaai people, who had almost given up on the earth, saw hope. Because as long as the human beings on Earth are extinct in this crisis, they will be able to rightfully occupy the Earth and make it another home for him.

In fact, the Yaai people could not choose to live on the earth temporarily, or use some forceful means to make humans give up a piece of land for them to live in. This idea is indeed a good note. But any civilization that has advanced to the level of interstellar evolution knows that no civilization can allow other races to migrate to their own planet. Unless they are all exterminated, sooner or later there will be a life-and-death battle.

The armada of the Yaai tribe has reached the outer space of the Earth. They hid and waited quietly for all humanity to die under this crisis. It's just that no one thought that human beings had evolved under this crisis. Evolution, which would have taken thousands or even tens of thousands of years to occur naturally, has taken place in the midst of a crisis that has swept across the planet.

The Yaai people, who had been waiting for the extinction of the human race, panicked, and they knew very well what this evolution of the human race represented. This will mean that humanity will not perish in this crisis. It means that the Yaai people will not be able to receive the earth smoothly. They thought about taking the Earth by force immediately, but they didn't dare. Because the punishment of the Interstellar Alliance for invading a lower civilization or a civilization similar to itself is completely different from invading a civilization that is just beginning to evolve interstellarly.

The Interstellar Alliance may ignore the invasion of lower civilizations because of the strength of certain civilizations, or it may simply punish the races that invade lower civilizations. However, the Interstellar Alliance will never be soft on invading civilizations that are undergoing interstellar evolution, and other civilizations can also use this as an excuse to declare war on civilizations that are invading civilizations that are undergoing interstellar evolution.

The Yaai wanted to destroy all humanity overnight. But that would be a serious blow to the planet. They need a place where they can recuperate, not an earth that will take hundreds of years to build. At the same time, they did not dare to bet that the Star Alliance did not know what was happening on Earth.

Some of the Yaai people couldn't wait any longer and launched an attack on the humans. Attempts to exterminate humanity with replicants. When other Yaai high-ranking officials learned about it, they immediately stopped this behavior.

Just when there was disagreement within the Yaai people, they got two pieces of news. One is that they had sent out an expedition ship before their home was attacked, and had discovered a planet that had not been recorded in the Interstellar Federation as suitable for their Yaai people. The second message is about the monsters that have appeared on the earth. It is precisely because of the second news that the Yaai high-level completely abandoned the earth.

Overnight, the Yaai withdrew all the forces hidden on Earth, destroying everything they could not take with them. But one of the Yaai tribesmen named Stanin remained. He is not willing to be defeated by humanity, he wants to stay here and create a greater crisis for humanity, and even he wants to destroy the planet before a greater crisis for humanity comes. Destroy what he can't get.

In front of the largest base in HB province, the ground has been stained red with blood. The rain in the sky had no intention of stopping. The rain washed the ground, washing the blood farther away, as if God were going to dye the whole earth red. Scattered monsters roam around the base, dragging away the corpses of monsters or humans and eating them. In the sky, flying monsters with lightning bolts that sometimes streak across the sky look down on the seemingly weak creatures in the base.

In the midst of this heavy rain, the insect monsters all cowered in the hive. People living in the wild take advantage of the heavy rain to go out in search of food. Even Han Feng's three bases sent teams out to look for food. The food reserves in the base are almost exhausted, and if you don't find something else to eat with the food, the food in the base will not be enough for even half of the people to eat a meal. Now it is the meat of monsters that is eaten almost every day. There are already many people who haven't eaten serious food in a week. Even high-level figures like Han Feng can only eat some miscellaneous and noodle steamed buns.

In fact, the lack of food is not sad for some human gatherings of hundreds of people, or teams of more than a dozen people. Because they only need to hunt some insect monsters or lone monsters, they can eat barbecue every day. But for a large base, it can't be solved by simply hunting a few monsters.

Heavy rain is still falling, and if there is a weather forecast at this time, people will surely find that this heavy rain has swept almost the whole world. The river is rising, and more monster eggs from the sea are entering the river. In some corners of the world, sneaky people brave the rain and head towards a place that is surrounded by monsters or has been completely occupied by monsters. A conspiracy from the Staimin of the Yaai tribe quietly unfolded in this heavy rain. -------------------------------- thank you very much for your messages, these are very precious to me. Now I go to eat, I haven't eaten for a day, and I can't even speak. When I come back after eating, I will write down the next change.
