The chance had finally come.
Ling Han and Chi Menghan were both rubbing their fists. This was the best chance for them to break through to the Spirit Transformation Tier in terms of strength of their souls, and what made the two of them feel that it was a pity was that that early stage Spirit Transformation Tier yin soul shouldn't have been killed so early, but should have been used to help them break through.
It was too late for regrets now.
Thankfully, they didn't necessarily require a great yin soul of Spirit Transformation Tier to take this step, but rather one in True Self Tier was enough, so they would have a greater range of choices.
They waited patiently. A month later, they saw the Western Desert King lead an army into battle. All his elite subordinates followed him, and there was no one to mine or guard the mine.
