In the video, Xu Xin's body gradually stabilized after Xu Ying grabbed his arm.
His eyes became extremely tired, and his voice was a little hoarse: "It's okay, I will accompany you."
...Are there only two of them left?
Xu Xin's eyes trembled.
His tired expression seemed to have exhausted all his energy from the several days and nights he had experienced in that instant.
...Is the flow of my own time starting to become chaotic again?
"Brother... wuwu..." Xu Ying tightly grasped the arm of Xu Xin in the image, tears could not help but flow down, and she buried her head.
"Let me continue." Xu Xin in the video touched Xu Ying's head, who was clinging to his arm, and continued, "Over the past thousand years, perhaps because we've unearthed the bloodline of the giant beast deep underground, it's affected the Earth's vital veins, causing the entire planet to expand."
"We originally thought that the expansion of a planet would cause huge changes in the world. After all, if a planet's mass remains constant and it simply grows, its gravity will change significantly, which would also cause huge changes in the atmosphere that is attracted to the planet's surface by gravity."
"However, this did not happen. Even after thousands of years, when the Earth's diameter expanded to more than ten times its original size, the Earth remained the same. Aside from its larger surface area, nothing else had changed. Even the species on Earth remained largely unchanged."
Xu Xin himself has a deep understanding of this.
When he came here, he discovered that the creatures here, except for being a circle larger than those on Earth, basically have no difference, and even their habits are similar.
"We don't actually know that. The changes within the Earth are too mysterious for us to explore." Xu Xin sighed, feeling the effects. "This planet truly holds many secrets. Even the bloodline of the giant beasts is only the tip of the iceberg. Perhaps this is also why those alien invaders were willing to leave their main force behind for thousands of years, or even migrate to this planet en masse."
...collectively migrate to this planet?!
Xu Xin's eyes widened.
In other words, what he has to face now is really this population of alien creatures?!
He immediately thought of the back of the planet and the giant tree that was brightly lit and blocked out the sun.
Could that be where they live?
...After going out, I must ask Shi Wanyun carefully.
Even if it means using violence!
If the back of this planet is really what he guessed, then this woman is in big trouble!
"I can't tell you about alien invaders yet. You don't need to know at this stage. You need to discover it yourself," Xu Xin in the video whispered. "However, since you already know about the underground world, I can tell you that it was created by the movement of the Earth's crust during the expansion of the Earth."
It is true!
He knew how any creature could carve out such a huge space underground.
It really is naturally produced!
"Oh, by the way, there's one more thing. In order to ensure the continued reproduction of the human population, we have also taken another measure."
"Before the war, we moved a large number of humans into a secret underground space to survive. For the next thousand years, they remained undiscovered and thrived quite well," Xu Xin chuckled. "Because I was the one who led them underground, and I've appeared several times over the past thousand years, meeting different generations of that group. They all seem to... believe I'm a god, and have even erected countless statues of me."
Xu Xin felt that his brain was not enough.
...Didn't he just casually mention something very important?
In this world, it turns out that there is a human race that has existed underground for thousands of years!
……Grass!
This is amazing!
"By the way, I'm also a god!" Xu Ying, who had recovered, pointed at her nose and said, "They also built a statue of me!"
Isn't this a bit outrageous...
However, Xu Xin in the video did not continue to talk about this matter. He simply mentioned it casually and then continued to talk about the giant beast.
"The blood of the giant beasts has influenced the entire planet, making all animals on the planet more or less possess the blood of the giant beasts. You should already be aware of the function of this blood. It can resist the control of the blood pattern mutation of alien invaders."
...Xu Xin actually wanted to hear more about the human population.
This guy...
If it weren't for the fact that this was a recorded video, he would have interrupted the other person long ago.
"In our timeline, the alien invaders only discovered a way to control the bloodlines of the first generation of giant beasts after more than two hundred years. But in your timeline, the giant beasts have already been bred for many generations using the controllable time factor. Their genes are extremely complex and mysterious. Even if they study for thousands of years, they will not be able to succeed."
"Until now, we are still in a tug-of-war with them. This situation is in our favor. From now on, we need you to work hard."
In the image, Xu Xin looked at him with a serious look.
"Well... As for your situation, well... we didn't really think much about it when we sent you to the future."
There was a hint of embarrassment in Xu Xin's eyes.
"Although you are my past self, as a false and illusory future, I actually have little to do with you anymore. Your actions can no longer have any impact on me. So..."
