As Lonely As the Ocean

The underground passage and the mountain cave were covered with blood and broken limbs.

When the three knights entered, they almost killed all the dare-to-die fighters that Zhang Taixuan arranged here. Zhang Tie came all the bloody way to the cell where Ma Aiyun was detained. 

Although Zhang Tie could neither use his battle qi nor his ability as a divine dominator, his sheer strength was also shocking. The cell was girdled by arm-thick alloy rails. The iron gate was locked. Zhang Tie didn't feel like searching for the key; instead, he directly pulled apart the hard alloy rails, exposing a big hole.

Ma Aiyun was lying on the ground in a coma. After being brought here, she had already lost her consciousness due to force.
