Noticing that Yuki was too quiet, even Ren decided to take a peek at the sky, and he also was left speechless. Even Leon was quite surprised that the zombie snake obeyed his thoughts from so far away... not only that, it could actually emanate fire from its body on the outer space. That monster was something else, but Leon already knew that since it took him months to kill it.

"Very impressive, right?" Leon said. "I was inside that thing for only God knows how long... and now it is under my command. I didn't want to use that spell, but some bastards are messing with me, so I don't have much choice but to use it. Anyway, can we talk now instead of fighting?"

"That was very funny... as if a human being could control something like that," Ren smiled nervously.

"Then how about this..." Leon said.

The next moment, the snake started to move around the Earth. Even though it was fast despite its size, it had to move for ten seconds to complete a full lap around the planet. It was hard to be sure, but if the snake was five times longer, it could bite its tail while circling the planet like an ouroboros.

"That was... just a coincidence," Ren said.

"I guess your skepticism has no-limits..." Leon frowned. "Do I have to make the monster land on the planet for you to understand that I'm not joking?"

Yuki, Ren, and the guards were utterly defenseless. They forgot that Leon was a threat, and now they were wide open. Although it was quite sad to be treated like that by his old friends, Leon didn't have time for that. Yuki, Ren, and the whole of Japan were fine, and that was good, but Leon didn't have time to celebrate. For some reason, Yuki waged war against the allies from the past, and Leon had to confirm what she did... if Maya, Amanda, and his friends died due to her actions... Leon wouldn't be able to forgive her.

"Asking you this, it is a waste of time..." Leon said. "Did you guys register what happened over the years? I believe you two would at least give the order to someone do that..."

It took a long while before Ren and Yuki could recover from the shock. Despite that, Leon couldn't make them hurry. So, he just practiced Zen while they stared at the zombie snake as if they were zombies themselves.

That skill wasn't on the level of Meditation, but it was almost as efficient. Anyway, things got noisy outside the palace. Since Japan recovered itself, the country was quite well illuminated during the night, so most people only noticed the zombie snake moving around Earth after the word scattered.

"Yeah, four years after the monsters appeared, I met you two," Leon answered. "For me, only seven years have passed since then, but for you two, nine hundred years have passed."

"How exactly you know that?" Ren asked. "How is that even possible?"

"Because I was summoned to another world and there, I discovered that time passes ten times faster in different stages of the assimilation," Leon explained. "The few times the world changed, new dungeons appeared, right? Some dungeons stopped working entirely because of those changes... it is because the amount of mana on the planet increased. I learned that when those events happen, it is a sign that the planet is advancing to the next stage... the people of the first planet I visited said that it was a part of the assimilation system and the system has several stages."

Ren and Yuki looked at each other as if they heard the most stupid bullshit... even if they were to believe it would take a long while, so they guided Leon to the archives room of the castle. There Leon found Ryoko, Ren's number one subordinate... Although she was a warrior before, it looked like she became more suited to collect intel and register things rather than fight. Regardless, she didn't recognize Leon either, and she clearly showed her displeasure because someone who looked like a beggar entered her workplace.

"Ryoko, our... guest... wants to see the oldest documents we have since the monsters appeared," Ren frowned. "We need any file directed to America and the events that happened soon after the monsters appeared. Is that enough?"

"For the time being, yes," Leon answered. "But I also want to learn about the biggest events that happened after that."

"...What are you going to do once you learn about what we did to America?" Yuki asked.

"That will depend... unless you have some good reason, I will retaliate," Leon said. "Even if you had some good reason, I won't forgive you if you caused the death of my family and friends."

"What are their names?" Yuki asked.

"Amanda, Maya, Hector, Betty, Sasha, Gisela... and I guess Lennart, Tom, Sarah, and Pedro da Silva," Leon said and then rubbed his chin.

Leon only talked with Pedro one or two times, but he had been quite helpful. As for Lennart, Sarah and Tom, they were a bit close than Pedro, and they also helped Leon in some situations. Still, he was wondering if he would go to attack Ren and Yuki if they died due to their actions.

"Ah, those guys..." Yuki said, visibly displeased. "I tried to kill them many times, but they are strong... as strong as us... We waged war against them, but they survived and fled."
