For the next half a month, Su Zimo discovered that Night Spirit - the mysterious little beast - was extremely picky with its food.
It did not touch the flesh of ordinary demon beasts at all.
When it came to ancient remnant beasts, Night Spirit would choose to eat some.
It did not seem like it enjoyed them either, eating very little.
Su Zimo did not give much thought to it, merely assuming that they had not found the right food.
After all, most demon beasts would not eat every other demon beasts as well - they had their own preference too.
Su Zimo planned to wait till Night Spirit was older before taking it out so that it could hunt on its own to see the type of demon beasts it preferred.
As time went by, Night Spirit's body began to turn rougher as though something was growing out.
A month later.
The disheveled old man came for a sudden visit.
"Zimo, I've got good news!"
