Chapter 579: Saving it

Zephyr saw the object in Eren's hands, which made his expressions darken. The worst possible thing had happened for him. He didn't think Eren was able to find out, especially since it was kept in such a secure place.

The small grey box looked so ordinary that even Eren couldn't recognize it. If it wasn't for his Identification Skill, he would have still been confused about the purpose of the small box.

Even if Eren maintained a calm exterior, but deep down, his heart was racing. He was worried that the power balance might actually be broken, but thankfully it wasn't.

Zephyr wasn't strong enough to face the Overlords. He had just awakened, which was his weakened state. There was no way for him to be this strong in this state, even if he was an overpowered Necromancer.

Despite that, he was able to show such overwhelming strength. It could only mean that he was taking help from an external object.
