"This all is related to this land's spiritual energy." Xiao Bao answered.
They all fell silent as they carefully listened.
"As master Cheng has said, everything has a spirit." Xiao Bao started. "The trees also have a spirit and they can cultivate until they form their spirit body that they will imitate from humans. The animals also can cultivate, too, and become humans. Some people who will discover their existence would call them demons, but they aren't." he explained. "We aren't," he added.
They understood. Sword spirits are the same as the trees and the animals. And xiao Bao… the one before them is the sword spirit's spiritual body. The sword is his real body.
"The difference between us spiritual entities, or I will call us 'phantoms'." Xiao Bao continued. "Our first difference from the demons is that we are spirits. The second difference is that we are 'born' as pure. Thirdly, we bear no ill will." He explained.
