Green Serpent House is one of the many places that you will get to visit while playing Phantom Blade Zero. But there is an underground passage that may be difficult to spot if you do not know about its location. Discovering the underground passage will enable you to uncover some secrets of the house.
How to Open the Green Serpent House Hidden Passage
If you want to access the secret passage, visit the Green Serpent House located in Pangzhen. Here, you will see that there is a huge door which has a design of a serpent on it. But you will not be able to enter because there are three pieces missing in the serpent, which include the Red Serpent Tongue, Black Serpent Fang, and White Serpent Eye.
Red Serpent Tongue Location
Return to the house of the Red Serpent in the Crimson Forest. For this task, you will require the Flaming Mane power. This is an ability that you receive after beating the Mask-Bound Lion Dance Grandmaster known as Flame. Burn the branches barring your way using the Flaming Mane power. Once inside, collect the Red Serpent Tongue.
Black Serpent Fang Location
After that, head for the Black Serpent House found in the Village of Lu. Once there, you will see some branches obstructing your way. Burn these branches with Flaming Mane, enter the house, and retrieve the Black Serpent Fang.
White Serpent Eye Location
The last thing can be found in the White Serpent House located on an island in Meigu Lake. In order to get it, you should unlock the Sha-Chi Powered Boat and then get to the island through the lake. Once you get there, you should defeat the Heartpiercer, who is an Elite Shadow Warden. After the fight, enter the White Serpent House and collect the White Serpent Eye.
How to Unlock the Hidden Passage
Once you acquire all three objects, head to the Green Serpent House in Pangzhen. Interact with the green serpents on the door and place each object in its rightful place in order to unlock the secret pathway to Mirage Estate.
Important: Before entering Mirage Estate, make sure that you complete all your unfinished quests. You should complete all necessary quests for the perfect ending, since entering Mirage Estate means a significant point of no return, where failure of some quests becomes possible.
