An Lin was able to discern fruits at an extremely fast rate through the use of his Divine Inspection Technique.
There were over a thousand fruit trees, among which there were five hundred fruit trees outside with the colors on the rainbow spectrum. If he searched at a rate of ten seconds per tree, it would still take him about eighty-three minutes, which wasn't too bad.
The time limit on this activity was two hours, so he would make it before then.
However, the only thing that he was concerned about was that someone else would take the immortal peaches before he did.
But that didn't appear to be very likely. If one went by luck, then the probability of getting an immortal peach was extremely low. If they carefully discerned the fruits one by one, then it would be extremely time-consuming.
