Su Jin was tallying up the number of Crystal Cores their family had obtained from killing zombies over the past three days while they were outside.
Since the third day mainly involved collecting items, they had a total of over thirty-six thousand Crystal Cores, among which the number of Mutated Crystal Cores was quite considerable.
"So, selling stuff really is the most profitable way to earn Crystal Cores," she concluded.
Su Jin reached this conclusion.
"Without strength, having materials is also useless,"
Lu Hao said, smiling. Killing zombies was to increase the family's strength and safety, which complemented selling materials.
"That's a must, everyone is getting more and more powerful now,"
Su Jin said, looking back at her family who were teaching Nie Qing how to play badminton.
"This one with wings is called a badminton, so what's this? An egg ball?"
