Eren watched as life drained from Trisen's eyes, his body collapsing onto the ground.
He kept the heart of the hero in his inventory, saving it for later. He couldn't let go of the ability to disguise as it was something that was quite useful.
He wanted to devour the ability right now, but he didn't want to let the guards see him eating someone's heart.
There were already too many rumors floating around about him being a true demon. He didn't want to blame your rumors.
With the man dead, it was only a matter of time before his body was going to lose the disguise. He couldn't let that happen. The Guards had already started approaching them after seeing him kill the person.
Right before Eren's eyes, the man's disguise was removing itself. His face and physique was slowly changing to his real self.
To protect this secret, Eren placed a talisman on the man's body. In an instant, his body lit in fierce flames that hid him from the view. The flames acted as a shroud, hiding the lifeless hero's body from the Guards.
He could use the flames to get rid of Li Yunfeng's body as well, but that would have been too obvious. Once it was investigated, the people were going to know that the talisman from the sect was used.
On the other hand, he didn't have to care about that here. He could kill this person without worries, even if it was in front of everyone's eyes.
Trisen was dead, unable to protect his body from the flames. Within seconds, his body turned to ashes that flew away with the wind. Only the scorching mark on the ground was left behind.
"I knew that person was lying. There's no way someone like him would know Elder Ren." One of the Guards said, stopping a few meters away from Eren.
Eren didn't even have to offer an explanation. The Guards made a justification themselves. Since the person was a liar and wasted Elder Ren's time, he was killed. There was nothing more to it.
Eren turned around, quite pleased with the actions of the Guards. He didn't show it on his face though. His face was still emotionless. If anything, his cold gaze made the guards hesitate, making them wonder if they made a mistake.
The guard also realized that it made sense. They had truly failed in understanding the man's intentions. They were fooled by that middle aged man just because he made up stories about some ring with such confidence.
"Next time there are people who claim to know me or want to meet me, I want you to inform me directly. You don't have to go through the extra steps of letting others know."
Eren handed over a communication token that allowed the guard to deliver a message to him. If another hero actually came, he wanted to be the first to know it so he could handle it stealthily.
From now on, these guards were his informant, and after that they were the guards of the sect.
The guard accepted the communication token, realizing the responsibility that came with it. At the same time, he also knew what a great opportunity it was to get close to an Elder.
"I will not disappoint you!" he exclaimed, brimming devotion,
Eren arrived at the library. Only after he entered the library, the guard returned. He had completed his responsibility as a witness without even realizing.
....
Another day passed. Eren didn't leave the library, wondering how long it was going to take before someone discovered that Li Yunfeng and his disciple had gone missing.
He wanted to return to his disciple to see her progress. He was also getting somewhat impatient.
'How foolish are the people of the sect? More than a day had passed and no one noticed it? Did I overestimate them?' Eren thought, sitting before an opened book that he had already finished reading.
He was wondering if he should send Yelen to check. Amidst his thought, he heard the sound of rushed footsteps on the other side of the curtain.
"Elder Ren! Something big has happened!" The Librarian's voice came while Eren smiled behind the curtain. Finally he could leave this boring place.
