Although the previous options mentioned that the Earth Spirit Fruit could enhance defensive power and physical fitness, it did not specify the extent of enhancement, so unless a test was conducted, Zhang Yanhang probably couldn't learn much more.
Of course, Zhang Yanhang could assess the Earth Spirit Fruit from other angles, such as its taste, which wasn't at all like apricot, instead bearing a resemblance to goji berries with just a hint of sweetness. However, taste wasn't really important; after all, he wasn't eating it because it was delicious, but for its effects.
Another important aspect was that, although the Earth Spirit Fruit grew on an apricot tree, it was unlike regular apricots in that it had no pit, meaning Zhang Yanhang could not reproduce this Heavenly Material and Earthly Treasure through planting.
