To kill the main character, he needed something that could make his life saving treasure useless. He needed something that could prevent the main character's escape when he was on the verge of death.
Even in his wildest dreams, he didn't want to give the main character an opportunity to escape as he knew it was a recipe for disaster.
In almost every fantasy novel he read, there was always a villain who was too strong for the Main Character. But they allowed him an opportunity to escape, only for the main character to return stronger and kill them.
This was the last thing Eren wanted, hence he had been delaying his plan. But if he could make sure that the Main Character wasn't able to escape, he could finally take the last step.
According to the Author, there was no Transmigrator in the Eastern Continent except him. Once the Main Character was gone, this was more or less a safe space for him, as long as he was cautious.
He wasn't sure how true it was, but according to Celeste, the answer he was looking for was in the Spirit Realm.
"Hmm? Now that I think about it, where is Celeste?"
Thinking about Celeste, he noticed that the little girl had been missing. She was not in his pocket and he didn't even know when she left.
"Yelen?" he called out the first spirit queen by her name.
Yelen turned around. She wasn't just Eren's contracted spirit. She was also his guardian. She could neither betray him, nor go against his commands. She was tied to him.
Yelen went down on one knee, properly greeting Eren for the first time like a guardian.
Felona and the other spirits who had found out Yelen's identity were shocked to see their first spirit queen on her knees before a human.
"Ancestor, you don't have to-" Resphi tried speaking, but her back turned cold when she saw Yelen's glare.
"Little child, I would advise you to think about your next words carefully."
Resphi closed her mouth and didn't utter a single word. Eren didn't have to guess hard to understand what Resphi was about to say next.
"I wanted to ask you something with just the two of us," Eren told Yelen, ignoring Resphi and others.
"Yes."
"I thought so." Eren nodded, expecting that answer.
It was too obvious. The moment she was summoned, she appeared to have been prepared for it.
"My next question... Have we met before today?" Eren asked the first spirit queen.
The Spirit Queen looked back at Eren. "I don't understand why you are asking me these questions."
"The more hesitant you are, the more I can see that I am on the right track. So answer me, did we meet before today?"
Eren had only seen a glimpse of Ren's past. A lot of that was still a mystery. With the first spirit queen, he had a feeling that he was close to uncovering something.
If she already knew about him before today, that meant there was a high chance that she knew a lot more that she was not telling.
With Yelen's hesitation, Eren repeated the question. The spirit mark once again activated as Yelen hadn't followed his wishes by answering.
This time, Yelen couldn't control herself and fell to her knees, holding her chest tightly, feeling a throbbing pain.
Normally, a Spirit Contract wasn't able to inflict pain on a Spirit. But the Guardian Spirit was different.
"Even I don't want to hurt you after you helped me, especially when you had to kill your lover with your own hands to save me," he said, not liking the feeling of hurting his own guardian.
Still, he could not ignore these questions, as this might be another link to the past that he wanted to find out.
He further stated, "These answers are important for me. So please tell me... did we meet before today? Or rather, how did we meet?"
With her hesitation, he already guessed that the answer was yes. Ren had met Yelen before, but how and when? That was the question.
Yelen raised her head. Her lips opened as she finally said something. Her lips moved, and with each passing second, Eren's expressions darkened.
