The warm current broke under Khan's violent swimming technique, but its traces stretched ahead, allowing him to follow the intended path.
Khan swam through most of the lake before finding another underwater tunnel. The channel was even narrower than the previous one, but the warm current was still there, so he resurfaced to refill his air bubble.
The break only lasted a second. Khan immediately dived into the lake again out of fear of losing the warm current. He didn't need to hurry so much, but his curiosity pushed him to do his best.
