"Phew!"
Xiahou Danxin raised his right hand, and unexpectedly, he was holding a fist-sized blue square crystal.
He exhibited a look of utter astonishment, closely observing the crystal as his shoulders began to spasm:
"Fuck! Fuck fuck fuck!"
"The Third Crown Rank gifted me a 'Life Crystal'! It's a treasure that can extend the life of mechanical beings, rumored to be mixed with its Divine Blood, and effective for mechanical authority too..."
"With this thing, could I possibly live another two or three thousand years?"
Xiahou Danxin hopped and jumped around, then fiercely swallowed the crystal. His pale and dry hair visibly turned gray and became lustrous.
He took a long breath, suddenly feeling itchy all over, and forcibly scraped off a layer of facial skin.
"Main brain! I need a bath!"
"Clang clang!"
