Ling Chuxi was fully focused on studying the runes on the ancient Bell. This was the first time she had come into contact with a venerable realm spiritual weapon, so of course she had to study it carefully.
Compared to the heavenly domain, the craftsmanship in the venerable realm was obviously different.
Let's talk about the materials first. Some of the refined gold and Mithril used to refine the heaven and earth Thunder Bell were already on Ling Chuxi's body, while some were never heard of or seen before.
Furthermore, some of the arrays used in refining weapons were similar to those in the heaven domain, but there were also some that were beyond Ling Chuxi's scope of understanding. If she were to look at it from the perspective of the heaven domain's laws, it could simply be called an array, and it was impossible to refine weapons.
