Sign-In could be repeated in front of the demon's den until every demon inside was defeated by Lin Jiufeng.
Such a system prompt had always only been in Lin Jiufeng's dreams.
He now had a place in the Cold Palace where he could Sign-In indefinitely.
Moreover, the people he would be defeating were all very powerful demons.
The rewards he could take upon defeating them were bound to be decent at the very least.
"Not bad, not bad. This Cold Palace really is full of treasures," Lin Jiufeng said happily.
The white cat looked at the joyful Lin Jiufeng in confusion.
"There's a demon's den deep underground, what do we do in the future?"
The white cat wrote and asked.
"We will live the same life as usual. The demon's den has already been sealed by me," Lin Jiufeng said casually.
He wasn't afraid of this demon's den.
