There wasn't any fence that could be seen with the naked eye between the area of the blue hole and the area of the open waters, but the invisible electric fence was even more powerful. The moment Gu Nianzhi managed to get out, she swam towards the water's surface. This time around, there weren't violet electrical arcs attacking her from the top. She surfaced from the sea, removed her diving mask, and inhaled deeply.
The people on the lifeboats and ships nearby saw Gu Nianzhi surface and cheered loudly. They were all glad that she managed to escape death from the horrendous violet electrical arcs. Gu Nianzhi heard the cheers and waved cheerfully at them. Everyone forgot which side they were on at that moment. They only felt that someone had managed to surpass a threshold, which no one had done before, and were all happy for her.
