If it didn't exceed five years, there was nothing to worry about. Just as he had done in Jinyun Immortal City, he would follow, find an opportunity to poison the target and put the matter to an end.
The main reason for setting a five-year limit was the issue of the Immortal Boat.
This time, in order to avoid any accidents, he spent a large sum of money to rent a Heavenly Immortal Level Boat from the Black Divine Tower. A Heavenly Immortal Level Boat was a mid-tier spiritual treasure usually affordable only to gold core cultivators in the late-stage Golden Core, and even up to Golden Core Peak stages.
Five years' time would cost a huge amount of spirit stones. If it exceeded five years, his business would have been for nothing, and he would have wasted years of time and earned a bad reputation with the Black Divine Tower.
If it was within five years, the cost of renting the Immortal Boat could be deducted, and he could still make some profit.
