"Thirty years doesn't seem like a short time."
However, the soil in interstellar space is extremely weathered, making it difficult to grow plants, let alone cover them with greenery.
In particular, there are people constantly causing trouble behind the scenes, trying to destroy the entire interstellar space.
“I tried planting them, but the trees died very quickly,” sighed Old Gu.
"No matter what, we must try. Even if we can't completely cover everything, it's better to have tried than to perish in the end."
Qin Su insisted that while she might not be that good at combat, she could still give it a try when it came to planting.
"How about this, Mr. Gu, we'll go out and divide up the areas later to see if we can plant a batch of crops."
She refused to believe that in such a vast interstellar space, not even a single green plant could be grown.
"good."
Inspired by her, Mr. Gu also became full of energy.
Qin Su was about to go out, so Huo Sijin quickly came back to keep her company.
Huo Sijin clearly knows this land in the interstellar space very well.
“I have measured the moisture, temperature and humidity here before. Compared to other places, the conditions here are the most suitable for planting.”
Even so, the temperature difference here is still very large, and the moisture is particularly scarce, so the humidity is naturally insufficient.
"To improve this land, we must bring in some fertilizer from other places."
Qin Su frowned. This piece of land alone could be transported from Earth with soil.
But interstellar space is so vast, there's definitely not enough soil on Earth.
Therefore, to improve the soil here, we must find other ways.
Seeing Qin Su deep in thought, neither Huo Sijin nor Old Master Gu dared to disturb her.
Looking at the vast expanse of yellow earth, both of them sighed.
In fact, back then, this place was also a grassland with abundant water and grass, and herds of cattle and sheep were everywhere.
At that time, high technology suddenly emerged, and more and more people liked the high-tech lifestyle, neglecting the land around them, causing large-scale soil erosion.
By the time they came to their senses, it was too late.
Some people tried to change the environment, but it was no use; they could only watch helplessly as the interstellar space became desolate.
"I want to travel to other parts of the interstellar world."
The soil of interstellar space may lack the same thing; what is available here may not be available there, and vice versa.
If these factors can be combined, then improving the soil will not be so difficult.
"good!"
Huo Sijin listened to her in everything; as long as there was no danger, she could go wherever she wanted.
"I'll go too."
Old Gu echoed, saying that although he felt it would be difficult to improve the soil and plant greenery, he had a gut feeling that Qin Su could accomplish this impossible task.
Huo Sijin glanced at him: Why are you always getting involved?
Old Gu touched his nose and chuckled.
“I can help. There’s strength in numbers. With me here, we might be able to find a solution sooner.”
Huo Sijin glanced at him again: "You haven't come up with a solution after all these years, what solution do you have now?"
Old Gu: ...
He felt he was being looked down upon, but he actually thought it made perfect sense.
But so what? He just wants to follow Qin Su and watch her find a way to cover the area with greenery; that's a great thing in itself.
So, when the aircraft took off, Old Gu went along with it.
Xie Erxun wanted to go too, but the clinic needed him to stay, so he had to stay.
"Waaah, Master, I don't want to leave you."
Qin Su patted him on the shoulder: "The clinic needs you. Do a good job and I'll bring you a gift when you come back."
Xie Erxun's eyes lit up immediately: "Okay, okay, then you can't forget, Master."
"good!"
Old Gu curled his lip, "What kind of gifts can we bring from this crappy interstellar space?"
But it's better that this kid doesn't go; it saves me from having to deal with his endless questions.
"Miss, you must come back soon."
Aunt Zhi was reluctant to part with Qin Su, especially since she herself had an accident while making the aircraft, and she was now even more worried about Qin Su.
But she also knew that the young lady had to go; it concerned the entire interstellar space, and she had no reason to stop her.
"Okay, Aunt Zhi, don't worry, we will definitely come back safely."
Qin Su agreed and boarded the aircraft to leave.
Their camp was located in the eastern part of the interstellar space. Next, they were to head south, west, and north respectively.
"Let's go to the south first. The south has the most fertile land in the interstellar space. When I was young, it could be called a land of fish and rice."
Mr. Gu recalled that it was there that he met the Holy Doctor.
Everything was so beautiful back then.
"Mr. Gu, was your first love also here?"
Seeing the longing on his face, Qin Su couldn't help but smile.
Old Gu blushed and said awkwardly.
"Is that not allowed?"
He did not deny that that fleeting glimpse back then had completely captivated him.
Qin Su blinked, surprised that it really was true.
"So, Mr. Gu, who was your first love? Didn't you manage to win her over?"
She had heard Xie Erxun say that Old Master Gu had been alone his whole life and had never had a woman by his side.
"No, she already has someone she loves. I'm too late."
If he could do it all over again, he would definitely have taken the person back, and then none of the subsequent events would have happened.
Seeing his regret, Qin Su didn't say anything more.
In this life, some regrets are irreparable.
After disembarking from the aircraft, she quickly examined the soil.
However, the soil composition here is even worse, lacking not only the components that are lacking in the east, but also many other components.
This unsatisfactory result made Qin Su's heart sink.
"Don't rush, we can also go and take a look to the west and north."
Huo Sijin offered words of comfort, but the situation became even worse in the west and north.
"Even if you mix these soils together, you still can't grow any green plants."
Qin Su frowned repeatedly. Where could she find suitable ingredients to improve the interstellar land?
"Actually, there's another place we haven't been to yet."
After hesitating for a long time, Old Gu finally revealed the forbidden area of interstellar space.
That place is forbidden to everyone in the interstellar space. The reason is simple: the forbidden area is too mysterious.
Many people who had entered the forbidden area never came out again.
But outside the forbidden area, one can hear the chirping of birds, beasts, and insects, and the flowers and plants growing inside are even more beautiful.
"There are places like this in interstellar space!"
Qin Su looked at Huo Sijin: "Have you been there?"
Huo Sijin shook her head: "Su Su, that's not a place to take risks."
As a space god, he wouldn't fail to observe that place.
Even before the interstellar war, he had deployed countless robots into the forbidden zone.
However, none of those advanced robots returned.
They lost signal as soon as they entered the restricted area.
No one knows what happened inside the restricted area, but it is clear that entering the restricted area is a one-way street.
