The Coffin Jade Stone increases the chances of upgrading a sword to the Eighth Rank Flying Sword by fifteen percent.
Ye Rong held a long, jade-like stone with mysterious patterns and seals, which was the unsealed Coffin Jade Stone he had obtained earlier.
However, with the stone in his hand, he kept comparing it to his fake Eighth Rank Tiandu and Minghe Twin Swords for a long time, not daring to take that risk.
Damn it, these were still Eighth Rank Flying Swords tailored for Qingcheng disciples. If he wanted to resell them, he could definitely sell them for twice the price of ordinary Eighth Rank Flying Swords among Qingcheng disciples.
Furthermore, if he were to sell both swords together, the price would be even higher.
