It seemed he noticed his abnormal emotions.
Lin Yuheng was dumbfounded for a moment, then said with a wry smile, "What are you so surprised about?"
She picked up the pitted failure of the Heavenly Thunder Stone and said, "This is just a failure."
"Were you expecting it to be a space storage device?"
Jiang Fan quickly concealed his surprise and said, "I'm just amazed that a space storage device could be made this way."
Lin Yuheng replied, "Space storage devices generally fall into two categories."
"One is created by the artifact refining masters of our Human Clan, who extract the power of space and use their artifact refining techniques to wrap this wisp of space, forming the space storage devices you know."
"The advantage is that the space is very stable, unless the storage device suffers destructive damage or the material of the storage device itself decays over time, the internal space will always exist."
