Zhao Yi's face suddenly changed after hearing these words.
He had always thought that the Nether Tree had only invaded Earth City and Water City, but he never expected other cities had already fallen.
Considering each city was home to at least several million people, the mere tens of thousands here now meant that possibly tens of millions had perished under the Nether Tree's invasion.
Inwardly, Zhao Yi couldn't help but ask, "By devouring the lives of these common people, can the Nether Tree also grow stronger?"
The Nine Dragon Jade Seal quickly responded, "Reporting to my master, everything is a scarce nourishment for the Nether Tree; as long as it devours, it continues to grow."
Zhao Yi fell into an unprecedented silence.
The more he knew, the more pressure he felt inside.
He couldn't help but think about how strong the Nether Tree would eventually become, given that he had already dealt with it and had some understanding of it.
