Chu Sheng stared at the three supernatural materials before him for a long time, then finally set the Sharpening Rod aside.
Only the piece of flesh and blood radiating a crimson aura and the seemingly unremarkable crystal ball remained before him.
The flesh and blood radiating a crimson aura needed no explanation. It was simply meant to strengthen the Butcher's body.
The crystal ball, however, was an entirely different matter.
Its trait was hypnosis, while its concept was alteration, something he had never encountered before.
In Chu Sheng's memory, many hypnotic abilities seemed to use crystal balls, clocks, and similar objects as aids. This crystal ball's trait and concept seemed to extend in that direction.
With that thought, Chu Sheng drew the Butcher from his waist. At a mental command, the Butcher appeared before him with a strange cry.
"Wah-gaga!" The tentacles behind the Butcher writhed, while the Cat Fiend clutched in his left hand bared its teeth and hissed.
Yet looking at him gave Chu Sheng an inexplicable sense of reassurance.
Perhaps that was the sense of security the Butcher brought him.
A butcher with loyalty embedded in his usage cost offered an unparalleled sense of security.
Looking at the Butcher, Chu Sheng said, "Butcher, I've picked up two new supernatural materials recently. Time for an upgrade."
"Wah-gaga!" At his words, the Butcher raised the Butcher Knife in his right hand high, and the tentacles behind him writhed even faster. A hideous, terrifying grin spread across his face, revealing the long, slender zombie fangs jutting from his mouth.
"Easy," Chu Sheng soothed him, then continued, "Pick up those two supernatural materials on the ground and start upgrading."
Obeying Chu Sheng, the Butcher wrapped his tentacles around the piece of flesh and blood and the crystal ball on the ground.
