Improvement and conjecture_1

Tang Zhen's shop had become popular at an extremely fast speed.

It would be unreasonable if he wasn't angry. After all, he was giving money to his customers, and it was the kind that could knock them out.

Who would want to miss out on such a good opportunity and ensure that there were no problems?

A successful trade brought confidence to the other cultivators who were watching, and they began to trade with the shop eagerly.

Their refining arrays had many years of history, or they might have problems with low refining efficiency.

Although it was a masterpiece, it was only superior to ordinary arrays, but it was not that it was without flaws.

Looking at the refining array displayed in the shop and comparing it with the one in one's own house, it could be said that one could immediately determine the superiority.

Under such circumstances, trading the old for the new to obtain a more advanced version was only natural.
