As they grew increasingly deeper, Zhang Tie felt an increasing pressure that acted upon his protective battle qi.
It was like how a diver deepened into the ocean. The deeper he reached, the greater pressure he would suffer from the sea water.
However, Zhang Tie was not in the ocean, but in the scorching magma.
In the same depth, the pressure of magma was 2.5 times that of the water pressure. Canglan Palace of Bloody Soul Temple was about 5,000 m deep in the magma, the pressure at which location was equal to the water pressure deeper than 12,500 m. Anyone below knights would be crushed into pieces by such a great pressure, not to mention battle spirits who had formed protective battle qis. Even knights would not feel good under such a great pressure.
