Eren didn't expect the Tower Master to call out his real name.
Even Feng Yu, Mist and the Holy Priestess failed to see through his disguise, so how did this person manage to find out? He didn't understand.
The only thing he knew was that it wasn't looking good for him if the Tower Master knew his real identity.
"Ren Necroline?" Eren asked, appearing confused as if the name had been completely unfamiliar to him. He also took a step back as the Tower Master landed right in front of him.
Unfortunately, his legs started feeling a lot heavier as the ground beneath him became darker. There was nothing holding on to his legs anymore, but still he felt as if something was pulling him down.
His entire body felt heavier and the dark ground started pulling him down. Before he could react, his ankles were already inside the ground, as if it was quicksand, pulling him inward.
"You can hide your identity. You can even gain these strange new abilities, but you can never cleanse yourself of the sins within your soul, now that you are in this territory."
The Tower Master looked at Eren, his eyes shining in an unfamiliar glint.
He reached out his hand, but he didn't touch Eren. Instead, his fingers stopped a few inches before Eren's throat. He appeared as if he was touching something very fragile that no one else could see.
"Hell is calling for you... The Sinner, deserves to return." He said, his voice carrying not even the slightest hint of emotion.
He was the one person who could see a thin black thread that was wrapped around Eren's neck like a shackle. The other end of the thread was within Hell itself, marking Eren's soul.
In the past, the soul thread was long visible to the Tower Master when Eren was within the Necromancer Tower. However, with the opening of the Hell's Door, the connection between this world and hell was becoming stronger.
His behaviour was slightly strange, even for the Tower Master. Not only was there no resistance from Eren, but strangely enough, there was also not much of a fear visible on his face.
Instead, Eren removed his disguise. Now that he was caught, there was no need to keep the facade. For the first time since he entered this world, he was revealing his real face as Ren Necroline in the real world in front of another person.
"How did you recognise me?" Eren asked the Tower Master, as if he had actually accepted his death.
"I found you with the guidance of Hell. It has been craving for you for a long time. The wait won't last long now." The Tower Master answered, fulfilling Eren's curiosity.
He lightly moved his finger and used an illusion to make Eren see the trace of the soul thread that was tied around his neck.
"As long as you are within the Northern Territory, you can't avoid the soul thread."
Eren frowned while watching the thread that was going in the direction of the Necromancer Tower.
"So it is something like a gps tracker on me. That is frustrating indeed."
From the words of the Tower Master, he also became certain that it only worked within the Northern Continent. That's why he wasn't discovered by the Tower while he was in other Continents.
Another thing he learned from the small clues was that only the Tower Master could see it. If that wasn't the case, the Left Guardian or the Guide would've caught him before he left the tower.
"Gps what?" The Tower Master didn't understand what strange words Eren was using out of nowhere.
By now, Eren was already waist deep in the darkness. His body kept being pulled down, leaving only a matter of time before he was completely engulfed.
"I assume you also know that I was looking for the Recording Crystal? Before I die, can I at least see the recording?" Eren asked the Tower Master who was finding Eren's behaviour even more strange with each passing second.
