Auron was at the second front line as he saw that the ruin's core was releasing a mysterious aura. He directly thought that it was something similar to the smell that the [Dark Ancient Plant] released. Because of that, he unconsciously closed his nose with his hand.
Auron knew that it would not work, but subconsciously Auron did that. When he released his hand, he could not smell the same pungent smell. So, Auron thought that this aura was different. However, not long after, he received a notification that made him frowned.
After reading the notification's content, although the aura didn't have any smell, but its effect was the same. Many thought immediately appeared in Auron's minds.
Auron knew this was a grim situation. Although it would not happen now, but it will come true sooner or later. After all, he knew the impact of such aura's effect from his experience at with the [Dark Ancient Plant] back then.
