"That instrument is too mysterious; its secrets still need to be studied."
Su Yu had previously told Tang Xiaomei that as long as they could understand the secrets of the Subspace Analyzer, Tang Xiaomei could be promoted to eight stars.
This was Su Yu's promise because the Subspace Analyzer originally belonged to Tang Xiaomei, and now that Su Yu had taken it, he certainly should offer some compensation.
But up until now, nothing has happened regarding the promotion, so Su Yu felt the need to explain a bit.
In fact, what Su Yu said before was not wrong.
This Subspace Analyzer is so mysterious; if its secrets are truly understood, it might not only allow Tang Xiaomei to be promoted to eight stars but even to nine stars or beyond without any difficulty.
However, currently, Su Yu only understands a small part of the secrets of the Subspace Analyzer.
So, he is temporarily unable to help Tang Xiaomei with her promotion.
