In Demon Slayer, I Get Stronger by Checking In

Ji Fan transmigrates to the world of Demon Slayer. Just as he is at his wit's end, a voice suddenly sounds in his mind.

"Ding! God-Tier Check-In System activating..."

"Ding! Activation successful!"

"Ding! Congratulations, Master! You successfully checked in at the Butterfly Mansion and received one-fifth of the inheritance of the Peerless Sword Saint."

"Since this is the Master's first check-in, the System has analyzed the traits of the world the Host is in and awarded the Host Extreme Breathing as an additional reward."

"Extreme Breathing: By using a special breathing technique, the user generates peerless power within their body. This power strengthens all of the user's attributes. When used against an enemy, it can destroy their bodily structure and make them vanish."

"Next check-in location: Mount Fujikasane. Check-in requirement: pass the Final Selection. If you can slay the Hand Demon, you will receive an additional one-fifth of the Peerless Sword Saint's inheritance."

Ji Fan excitedly leaped down from the boulder.

A God-Tier Check-In System!

I knew it, my golden finger...
