For the next few hours, Sam maintained the same lead as he created after realizing the use of glass boulders.
He kicked the boulders at Gran whenever she tried to throw the knives at him or whenever she tried to reduce the distance. He managed to keep that steady distance without any changes. But he knew that he couldn't go on like this. Because the glass boulders reduced in numbers and the rocky boulders took their original dominating spot and even they are not as dense as before.
On this way, Sam noticed the effects of this meteor shower on the land and the environment. He noticed that there is even an undead glass boulder that turned some beasts into undead and in fact it is so potent that it managed to create some undead trees which are extremely rare.
So rare that even in the realm of undead he only managed to see a few.
