He is still in the egg and has been using the opportunity granted to him to work his way up the ancestral tree, looking to go back to its source. So he expected to come across the imprints of powerful dragons who are already world gods. But he didn't expect that they would be able to trace the imprint back to him and even interfere in the ancestral trial.
It reminded him of how Soverick had the first meeting with the First Sage. It was just like this. It was by mistake, and Legion was caught off guard.
Legion's greed made Soverick continue to have more encounters with the first sage. But that experience has taught Legion a very important lesson. That lesson is to never have a meeting with a world god, so he is already regretting his greed.
The voice asked again. "I am still waiting, young one. What made your soul so strong?"
He decided to do the same thing Soverick had done in his first meeting with the first sage. He lied and said, "I don't know. I suspect that it is something my parents did."
He is pretending to be harmless. Soverick did so by not exposing the fact that he could leave the mental world of the first sage at any time and went along with the meeting. He can't escape from this meeting since it is the world god that came to him. But he can also pretend to be harmless.
The voice asked him in doubt. "Why would your parents invest so much in an egg?"
He shrugged mentally. "I don't know."
He is just an unborn dragon. How is he supposed to know why his soul is so strong? Or how is he to know the motives of his parents?
Even the voice agreed. "Never mind then. I shouldn't have expected you to know."
"Let us return to the matter at hand. Who do you think will win this fight? You have seen her fight. How well does the little tyrant hold up to her?"
Legion-8 replied confidently. "Little Lightning Tyrant will win."
Little Tyrant is the one called Fourth. He doesn't know which of the people in the trial he is taking is the ancestor of the trial since the objective has not been announced yet. But he is certain that Fourth will win this fight.
The voice asked him. "Why?"
Legion-8 considered the question carefully before providing the answer. "They are equally skilled, but Little Lightning Tyrant is more ferocious. Ferocity doesn't affect the outcome of a battle in normal situations, but it does in this case because the element that Little Lightning Tyrant is wielding is lightning. His ferocity has made him achieve synchronization with his element, which will make his lightning more powerful."
The voice chuckled and said, "It seems you are smart too."
Legion-8 gave an explanation for why an unborn dragon would understand the importance of synchronization with one's element as a dragon, "I have gone through a lot of trials and seen a lot of things. It is as if I have lived many lifetimes."
"You are right. The little lightning tyrant will win. I am the one they call the Little Lightning Tyrant. I won the 900-year-long trial to emerge as the final victor. I got the help of the dragon spirit and was able to fuse the laws of fire and lightning to create my concept. I became an Origin god and defeated my father. My deeds were known by many dragons, and I was called the Monarch of Fire and Lightning. Then I became a world god. From then on, I was called the Tyrant of Fire and Lightning."
Legion-8 exclaimed like a proper dragonling, "That's so cool."
He is genuinely impressed, but not enough to exclaim like that. He did it to maintain his dragonling persona. It seemed to have worked.
The voice chuckled and went on to brag.
"This trial involves the most important victory in my life that eventually led to my success as a world god. I defeated her and even procreated with her. She bore wonderful offspring, one of which is currently with me. Maybe you will meet him in the future, since he is technically your older brother. He is pretty famous too, so you can find him by asking around for him. They call him Little Tyrant now."
Legion-8 asked in anticipation. "Is he strong?"
The voice chuckled even more. It muttered, "Dragonlings and competition."
Then it said to him, "I know what you want to do. You want to defeat him. The best answer to that question is the objective of this trial. Fight his mother and witness the strength of a dragon with the power of space."
The frozen world began to shake. It felt like there was an earthquake. Legion-8 became on guard immediately.
He thought to himself, "It seems I was right. Something bad is about to happen."
The voice chuckled. It said, "The dragon spirit is not happy. It doesn't want me to interfere with your trial. I have to go."
That surprised Legion-8. He thought to himself, "First it was a world god, now there is the dragon spirit. I have kicked a hornet's nest of trouble this time around."
The voice wasn't so concerned. "I will leave you now, young one. Remember to find the Little Tyrant when you grow up. Continue your trial for now. Defeat her, and you will gain more than your answer. You will also gain my protection and the element of lightning."
The voice became silent and disappeared. The world stopped shaking after the objective of the ancestral trial was stated, and the interference disappeared.
Legion-8 gained control of Fourth's body for the first time in the trial. He stopped being an observer. His view of the world changed abruptly from an overhead view to a confined view from fourth's perspective. Then the world resumed.
He wasted no time in adapting to the changes brought about by becoming fourth. It is necessary since he wasn't even given the time to. The fight was already underway before the world froze, so he has been dropped right in the middle of it.
