He will gladly sacrifice a low-level planet if it means that he can still be the ruler of this universe later.
That is how the universe works. Only some things can be achieved with sacrifices; for a ruler of an ever-expanding universe, a low-level planet is insignificant, and they would gladly let a low-level planet be destroyed if it meant that he could rule longer.
But that doesn't mean the planet itself can't do anything about it. Like every other low-level planet, its conscience was sleeping and collecting energy from space and the living people on the planet itself.
He gathers magical or heavenly energy from space that the inhabitants can use if it upgrades to a higher-level planet. The difference between magical and heavenly energy is that you get magical energy when a planet naturally upgrades from a low to a medium-level planet. Heavenly energy is something that the planet will rely on when it is helped or forced to evolve to the next level through a God.
The 'energy' that the planet gets from its inhabitants is soul nourishment. Every time an animal or a human dies, that soul strengthens the world's core. If the planet can only get to a higher level with this method, this process will take billions of years. But with the help of magical or heavenly energy, it is vastly shorter, from billions of years to millions.
This low-level planet is getting attacked by something outside of this universe, and it usually can't do anything about it. But when it felt the dread that would come in the future, its instinct kicked in, and its conscience was forcibly awakened.
When awakened, it felt that it was too weak, and its inhabitants were really weak. He felt that way until he sensed a group of humans in a specific location. From what he could see, they were approximately hundreds of times stronger than the average human.
Another advantage is that it could feel that it was close to evolving to the next level and would evolve before the attack or the apocalypse happened. When it evolved, it could choose a champion for its planet, and that person would get astronomically stronger in a short amount of time. The champion had the luck and destiny of the world on his shoulders, so that person had a lot of challenges before him.
But it felt that the strong people differed from the rest of their race on its planet. He could tell that every one of them came from the exact same origin and that a low-level god created it. But these guys evolved from that cycle and started a new one.
They had a new origin, not the one the rest of the humans had. This one was much more powerful, so powerful that it couldn't even see its origin. But that wasn't really its concern because those people cared about the planet and didn't even try to destroy it, even though they were really sure that they could do that if they wanted to.
The planet will now focus on upgrading faster and nourishing its world tree so that the energy gets purer when it upgrades for the rest of its inhabitants, who have to adapt and evolve when it does upgrade.
....
Amaterasu looked at the sky with a smile on her face. She just felt that this world's core consciousness had awakened and observed them for a moment. She was a bit curious about what it was going to do when it felt them, but it seemed like it appreciated us more than thinking about killing us.
He could do that with its champion or at least try, but it looks like it will do something other than that. Amaterasu is now the headquarters of their cult, which has grown exponentially. It now has a base in every country on this planet, and its influence is steadily increasing. When his master desires, he can even become the king of a country or start a new one, and nobody would have any complaints.
Amaterasu even influenced the most important women in this world to join them. In total, thousands of women were influential enough for her to move, so she did that.
She made quests to the existing members to invite these women to the base and accept their new faith. Some accepted immediately because they were curious and bored with their daily lives, and the ones who resisted had to drink the liquid only once to submit to our Lord.
Those women were now just like the rest of the women training while showing the media that everything was normal. One even became a priestess because of her faith in our Lord. Originally, she was just a queen of a little country, but after getting to know us and accepting us, we decided to help her a bit in her country's affairs.
We let her study how to become the best queen she could be and how she could lead people in the light but also influence her country from the shadows. She absorbed every bit of knowledge she received and became more fanatic as time went by. Now, she spends only one day of the week in her country, and for the other six, she is at the cult's headquarters because she wants to get closer to her God.
Her country was struggling before, and it could have been another year. A coup would have been organized, and she would, at best, be dethroned and, at worst, be killed. Her country was small and only had a few trade options, so it was failing economically, and the country's residents couldn't travel outside of it because they couldn't afford it.
And that it lies between two giant mountains didn't help. Traveling was much more difficult because of them, and nobody wanted to go on a vacation to a country where they lived in a cold environment and were dirt poor. But now, after all the work she put in and the help of the cult, it was a beautiful county known for its clean nature and high living standards.
