"Return." The Demon Extermination Sword returned to Zhang Fei's hand as soon as he jumped down from the tree, with Jian Hei'an and Jian Guang'an sitting on his shoulders.
Zhang Fei checked the heads of dozens of beast corpses, but he couldn't find a single perfect demon core, and he only discovered other grades of demon cores.
"Tch! Perfect demon cores are hard to get!" Zhang Fei muttered in annoyance.
[I think you should hunt demon beasts with a cultivation at the Celestial Venerable Realm, Master. All the demon beasts in that area have cultivation below that, so their beast core is below perfect grade.]
"Yes," Zhang Fei thought the same as Mei. "The upgrade will be completed in half a year, right?"
[Yes, Master. You have been so busy over the past few months, and the system will undergo major changes in six months.]
"I can't wait for the changes."
"Master!" Jian Guang'an pointed towards the front. "There are many powerful demon beasts in that area."
