Wei Xiao Bei shook his head. He was a bit too greedy. There was already a latent power rune and two wind runes on the arrow. When he thought about adding another wind rune, the arrow had been turned to scrap and wasted his efforts.
Naturally, this was because of the material of the arrow. If he used better material, then even if his attainments weren't sufficient, he could still insert more runes.
In short, the better the material, the lesser the difficulty of inscribing runes.
As for the second arrow there were two latent power runes and two wind runes. This time he was not greedy.
However, the third and fourth arrow made Wei Xiao Bei feel as if he was out of luck. Perhaps because of the inferiority of the material, they were turned to scrap.
The fifth arrow finally succeeded.
Just like that, he finished refining two arrows.
Although the success rate was low, he was not discouraged.
