After Guarding the Border for Ten Years, I Lay Down and Became a God of War.

[You can improve your cultivation by sleeping] Lin An crossed the border and awakened the "Lieping System". When others practice swordsmanship, he sleeps; when others break through, he turns over. The Frostfang Wolf King attacked at night and split it in half with one sword—— Everyone: What grade are you in? Lin An: Don't make any noise, let me sleep for five more minutes, and I will be the God of War now.
