This was not a bloodline connection between the heavy armor knight and the giant earth demon rhino, but stemmed from the power of the spirit furnace.
There was a rare spirit furnace utilized by the 6 Great Sacred Temples, but which mostly appeared in the Knights Temple and Soul Temple, known as the Evolution Spirit Furnace. The greatest function of this type of furnace was evolution — It promoted the evolution of itself and its mount. The evolution concerned the power of the bloodline. When applied to humans, it evolved the outer spiritual power — within the 6th Rank, it could evolve by one rank; beyond the 6th rank, it could boost the outer spiritual power by two thousand. For magical beasts, it could stimulate the power of the beast's bloodline. For instance, the enormous earth demon rhino in front of them had evolved directly into a golden demon rhinoceros, just like Tao Linlin's Demon Suppression Tree, it had a golden bloodline.
