Mother Earth was said to be 4.6 billion years old, yet these grains of sand were even older!
Song Shuhang sighed inwardly.
With the improvement of his strength, his mastery over the secret appraisal technique was also getting better and better. Right now, if he were to accidentally appraise Earth itself, he would probably survive.
However, even after paying such a steep price, all he managed to identify was that the sand was 5 billion years old. Wasn't this akin to purposefully stifling his heart?
It would've been better if the appraisal just failed.
Could there be some other information that hasn't been transmitted to my mind yet? Song Shuhang's primordial soul didn't move and kept using the secret appraisal technique.
After a while...
The black-skinned Scarlet Heaven Sword asked, "Did you find anything out?"
Song Shuhang raised his head and said with a serious face, "Yes, I got a very old piece of information."
