"One-Star Windfury Key," "One-Star Storm Key," "One-Star Space Key," "Two-Star Resentment Key," and the "One-Star Moonlight Key" he obtained from Gu Yueyan finally amounted to enough materials for synthesis.
First, he synthesized one-star keys into two-star keys, and soon Ren Suo obtained the "Two-Star Moonlight Key" and "Two-Star Space Key." After merging them with the "Two-Star Resentment Key," Ren Suo got—
"Three-Star Key."
"Huh? Where's the extra effect?" Ren Suo was stunned for a moment. He went back to check the synthesis rules carefully and saw a passage he had overlooked:
"When all the materials for the key are broken down to their simplest form, and the number of low-star keys (below 2-star or more) exceeds half, the key will lose its special effects."
"So, one-star keys can be synthesized into two-star keys, but using these 'artificially made' two-star keys to synthesize a three-star key causes the loss of effects, huh…" Ren Suo muttered.
