In the game, if you want to improve your character's combat effectiveness, you must know how to complete the Three Days and Nights achievement in Genshin Impact 4.6. Only by solving this problem can your character become stronger and fight enemies more easily. If you want to know the solution to this problem, then take a look at the guide brought to you by the editor of Source Code Network.
1. First, the player enters the lowest difficulty level in the game [Sky-Swallowing Whale]. After the player enters the level, the whale will directly let the character swallow it.
2. Be careful not to kill the whale. Do some damage to speed up the anger bar. If the damage of the character you bring is too high, wait slowly.
3. After the player is swallowed, prepare skills directly and try to kill the monster with one set without giving it a chance to transform. After players defeat it inside, they will automatically complete the achievement [Three Days and Nights in the Belly of the Whale].
