Wang Tao had been able to attempt a Second Awakening a while ago, but with only a 40% success rate. To Wang Tao, this rate might as well have been zero.
Although he'd usually had good luck, he was not willing to gamble. Should he lose the bet, the next attempt at Awakening would demand even more Secret Keys and face an even lower success rate.
Later, he accidentally encountered a Catastrophic Serpent. After killing it, he obtained an Advanced Awakening Secret Key with a 70% success rate for himself, and the serpent also dropped a Solid Advanced Awakening Key.
With these two keys, Wang Tao's success rate for the Second Awakening had increased to 70%, but he still felt it wasn't safe. After all, he had a failure on record when fusing an Epic Crystal Core with an 80% success rate, even though it was just that one time, he had indeed failed.
If an 80% chance could fail, a 70% chance was naturally perilous...
