Four tall and stout Human Immortals from Indestructible Sect were seen walking up to the platform, together carrying a box made from yellow jade, three feet in both its width and length. They were breathing heavily, and with every step, their bodies shivered. These cultivators from Indestructible Sect were cultivating Earth element techniques; the techniques that used specifically to temper their corporeal bodies. Among all thirteen Immortal Dao Sects, they excelled in the strength of their muscles. Every single Human Immortal of Indestructible Sect had a muscle strength that was at least one hundred times stronger than any other ordinary Human Immortal. Usually, with every swing of their arms, they could unleash over one hundred thousand kilograms of pure muscle strength.
But now, with four Human Immortals from Indestructible Sect carrying such a small yellow jade box, why did it seem like they were struggling strenuously in moving it up to the platform?
