Even while carrying Ling Menglu, Long Dangdang didn't feel his speed was significantly slower than when he was alone. To prevent Ling Menglu from getting struck, his body had already collided several times with stones at the bottom of the waterway. The cold underground water numbed him to the pain, making it bearable. With undivided focus, he continued to press forward with all his might.
At this point, Ling Menglu's body's numbness was gradually subsiding. It was a relatively comfortable moment during her breath-holding phase — her chest cavity was compressed due to the water pressure, temporarily lessening her discomfort and allowing her to relax somewhat. However, she began to feel spasms in her diaphragm below her chest, a sign that her breath-holding time was nearing its limit. According to previous experience, this could happen after around four minutes. Once in this state, she would normally be surfacing for air.
