Since the day Ling Lei and the others have retreated in their secret base in the outer area of the Divine Demon Beast Region, two weeks have passed, during which they spent all their time learning how to make God Bloodstones.
It only took them two days to learn how to make God Bloodstones which was the easiest part. Now that they had a much deeper understanding of how to make them, the hardest part was to make a lot of them.
Being able to make Blood Godstone was very cool and its usage was simply beyond beneficial and valuable. However, making them was extremely draining because it required them to use their blood essence and power to make them wich kinda weakened them in the process.
They were the ones that always hunt and kill demon beasts to absorb their blood and life essence to increase their strength, but now they have to extract their own blood essence and power to create something to feed the demon beasts which would increase their strength.
