Xie Ji's eyes gazed at the figure before him. He had heard of the Immortal Village before. With someone like the Undying Old Man emerging from the place, it was near impossible for anyone not to have heard of the place.
What the Undying Old Man was known for was to keep things immune from decay, be it living beings or dead objects. His old vines were something that not even fire would be able to do anything about.
Du Ao wanted to escape from the mess he was in and went about killing passers-by to do it, but he had not expected the one he had burned was someone from the Immortal Village, and ended up paying the price with his life for it. It was something that would have left many outside deep in thought. The warzone gathered many geniuses from all over the Barren State, which meant that any carelessness could result in dire consequences.
Du Ao of the Sacred Fire Sect would have probably been oblivious as to who killed him, even at the time of his death.
