Before he studied the Mid-tier Fire Origin Star Pattern, Xu Jin had not felt the effect of the Red Scale Heart.
But when he was fully engaged in engraving the Mid-tier Fire Origin Star Pattern under the full light of the Star Lamp, the effect of the Red Scale Heart almost burst forth, presenting itself to Xu Jin.
The Mid-tier Fire Origin Star Pattern that Xu Jin was engraving was incredibly smooth.
After just a hundred attempts, he already succeeded once.
With Star Patterns like Whale Swallow, Rain Curtain, and Warm Dream, Xu Jin had to engrave at least two hundred times inside the Star Lamp before succeeding once.
For the Fifth Tier Middle Whale Swallow Star Pattern, inside the Star Lamp, Xu Jin had to engrave at least three hundred times before successfully completing one, with a hundred percent success rate, not until the thousandth attempt.
For the Fourth Tier Star Patterns, a hundred percent success rate typically came after six to seven hundred attempts.
