Chapter 509: Did Not Sleep At All (2/5)

Mei Mengzhen was somewhat surprised, but even more so, she was delighted. Looking at the situation, the black material was providing energy to the black soil. Yet there was one question—where had this black material come from? Was it produced on Earth? And why did it have an effect on the space soil? Furthermore, how long could this black material sustain the soil's energy? Was it continuous or temporary? And, could she acquire more of this black material in the future?

One by one, doubts surged in Mei Mengzhen's mind, but there was no doubt that these were questions she couldn't answer. Even the origin of the black material was unclear to her, and she couldn't let others know she was continuing to search for it. If there were any issues, those in the know would definitely become suspicious. Thus, this matter could only be set aside for now.
