Chapter 649 - The Spiritual fluctuation
Sam doesn't know how long passed but finally you can say he is already able to destroy 90% of that barrier and only the 10% remain. The great thing is that the energy of the limit breakers is still present in that place and it is still preventing that barrier from regenerating quickly.
Naturally that energy of the limit breaker provides Sam with additional spiritual energy and additional stamina. But Sam also realized one problem at that time. Because he is using the original spiritual energy, the consumption rate of the energy of those limit breakers becomes much more and he just hopes until he does not break that barrier completely that the energy of those limit breakers stay in that place.
