Chapter 240: Immense Experience

"It is something he called the Preservation Effect," she told Eren. "It was something he prepared before we entered the Great Demon Sect as he was worried that things might go wrong and he might die there."

"Preservation Effect?" Eren pondered out loud. "Is that another ability of his?"

"I don't know much about it, but it is definitely a very strange ability that even I don't understand. From what I understand, it allows him to preserve things, especially items that could only be used once."

The woman tried her best to explain that strange ability. As per her words, the man was her son. In the past, he wasn't like this, but a few months ago, he suddenly changed.

She still remembered how he started talking about some characters and novel. Ever since that day, he became more distant from her. She thought that it was just a phase, only to realize what a fool she was.
