Hi. Please could someone help me by answering me this question I have please? How did the king survived the fall?

He fell into some river or lake, so it is possible for him to survive it. That is all that is known. How he got out of water? Anyone helped him or did he get out himself? There is no answer. This is usual in dramas... if there is no dead body then the person is usually alive and returns to the story later. :)
