LitRPG: I Recycle Demonic Beasts In Underground Cave

In the Catacombs, there are countless beasts!
Ye Nan had traveled through Blue Star and obtained a critical strike recovery system that was billions of times more effective.
Ten times, twenty times, thirty times... a hundred million times critical strike!
In the Catacombs, Ye Nan looked at a Grandmaster level vicious beast, the Golden Armored Giant Lizard.
"Ding! Recycle successful! '"
"A million times critical hit!"
"1 billion spirit stones!"
"The Emperor Grade Combat Sword Scarlet Flame! "
"Origin Skill - Mad Dragon Breath Swallowing Art!"
"Shadow Talent!"
Through the recovery of vicious beasts, Ye Nan's strength continued to grow. However, his path was not Blue Star, but the entire... universe!
