Tang Zhong heard this, realizing that the tales of ghosts weren't just made up nonsense, but were spirits formed from accumulated evil energy.
It's just that the evil energy on Earth is rather thin, making the spiritual bodies fade in and out, hence some people claim to see ghosts.
Now, the spiritual bodies here can hear sounds, so they must also be visible!
"These evil energies, when combined with human obsessions, can create spiritual bodies. Did you hear earlier? That spiritual body said it died miserably, it was likely someone who died tragically that fused with evil energy to become like that!" said one of the Flame Dragon Soldiers.
"Can these spiritual bodies be absorbed?" Tang Zhong asked.
"No!" replied the Flame Dragon Soldiers.
"Doesn't that mean this thing is useless?" Tang Zhong asked.
