Xu Fan spent 3 months comprehending the Sun and Moon Rune fully, and the rest of the time was spent refining this Time Treasure called Time House of Hope.
At the moment Xu Fan input his spiritual power into the Time Hut, which took him countless brain cells to refine successfully, he felt a little disheartened.
According to the rune array he drew, the flow of time inside the Time Hut was twice that of the outside. That is to say, it would take him just over 60 years to break through to the Foundation Establishment Stage.
But he had overlooked one thing: the time law is the supreme law of the world. To drive the treasure infused with the time attribute, he also needed the power of time law.
So, for the remaining few months, Xu Fan went through various books to find a compromise using the easily accessible Sands of Space and Time as a medium to drive the Time Hut.
In his calculations, one pound of Sands of Space and Time could power the Time Hut for five years.
