Su Xuan buried the makeshift helicopter before he was ready to continue his journey with Qiuyue.
Actually, Su Xuan wanted to fly the small helicopter to search for the Heavenly Mountain Snow Lotus right away, but he didn't know the exact location of the Snow Lotus, nor where to land.
Without this information, flying the helicopter would directly expose his location and make it easier for Song Tianbao to find him.
With Song Tianbao possessing a small helicopter, it was too terrifying; Su Xuan didn't dare to bet whether Song Tianbao had something like a rocket launcher. To be safe, Su Xuan decided to continue the journey on foot with Qiuyue. After all, his life would last another week, to be exact, five and a half days since consuming a third of the Heavenly Mountain Snow Lotus.
Walking also had its advantages: a smaller target and easier to hide. Helicopters dispatched by Song Tianbao occasionally flew overhead, and Su Xuan could not be bothered to shoot them down one by one.
