Ye Xiao did not plan to use King El's beast skin to refine a single armor.
King El's beast skin was extremely tough, but compared to a few hundred pieces of Black-scaled Snakeskin stacked together, it could not be said to be too strong. That would be a little over the top.
Although the Black-scaled Snakeskin was strong, it was easily sliced by the imperial-level long-handled saber that he had refined.
Therefore, he should refine King El's beast skin and merge it with the Black-scaled Snakeskin.
That way, the benefits of merging the two would definitely far exceed the benefits of refining a single armor.
Ye Xiao took advantage of the fact that he had not returned to work yet and spent another day and night to completely refine the armor.
The outer appearance of the armor was still that of a black coat with black trousers. The head can be broken, blood can be shed, the cool feeling cannot be lost.
