The Sword God Is on His Last Legs, and the System Only Shows Up Now?

After fifty years, Lin Mo reached the pinnacle of swordsmanship and subdued the myriad races, only to be ambushed by his closest friend and hidden enemies from the Immortal Realm. His cultivation was destroyed, he was beset by hidden injuries, and he had only three days left to live.

Reduced to living in a ruined temple, he was mocked by the world as the "crippled old swordsman," barely clinging to life.

His past glory had faded like smoke; powerless to settle his blood feud, he could do nothing.

Just as he was about to burn away his remnant soul and take his enemies down with him...

The [Sword God Life-Prolonging Comeback System], fifty years late, finally activated!

"Not enough lifespan? Complete missions to gain extra days!"

"Lost all your cultivation? Exchange points and instantly restore your realm!"

"Your swordsmanship is incomplete? Deduce everything with one click and break through every technique!"

"Your enemies are too powerful? Just watch me cut them down with one sword!"
