Zhang Wei's was interested in this yet another heavenly treasure, "...What does the Heavenly Mirror do?" he inquired.
[Normally, it can create an exact replica of anything when enough Qi is infused by the user. However, its true potential has been lost over changing eras. The Heavenly Mirror was originally designed to replicate not just objects, but even dimensions. If you provide it with sufficient Qi, it can generate a small mini-dimension for you—a space where you can grow Gu insects without any hindrances.] The system's explanation unfolded.
Zhang Wei was slightly taken aback. 'So we can create an entire dimension inside it, akin to Earth?'
[You can, but it would require a substantial amount of Qi. For now, you can cultivate it within a few months to create a smaller space suitable for nurturing Gu insects.]
