In "Underground Castle 4," the Hidden Village is a concealed area located to the southeast of Darkfire Valley. Players need to meet certain conditions to enter and complete related quests. So, how do you pass through the Hidden Village in Underground Castle 4? To get through this place, players need to meet specific prerequisites, clear the corresponding areas or solve puzzles, and then complete all hidden tasks to obtain the final reward.

1. Entry Conditions
It's recommended that the team level reaches above 155 before exploring. Additionally, you need to complete three core missions involving ancient runes in the main storyline. Finally, you must defeat the 159-level elite guard to open the passage to the Hidden Village, after which you can teleport inside. After entering the Hidden Village, further exploration is required.

2. Exploration Process
On the periphery, you need to eliminate the Corrosive Slime group and collect bronze keys to unlock the storage room on the west side. Then, you need to solve the water channel puzzle, adjust the four sets of gears to the correct angles based on the water flow totem on the wall, and resolve the valve mechanism. In the end, you also need to battle the guards protecting the temple. It's suggested to bring equipment that can deal fire attribute damage to remove the regenerative shield.

3. Boss Fighting Tips
When facing the Immortal Priest, use frost bottles to slow down their casting speed and set traps at the edge of the battlefield to prevent reinforcements from small monsters. When encountering the Twin Magic Trees, weaken both of their health values simultaneously and use the flame altar on the field to trigger a chain burn effect. Next, have the tank absorb the damage while you focus on dealing damage from a safe position.

4. Triggering Hidden Plot
If you want to witness more interesting or fun plots, look for the glowing stone slab at the withered altar in the northeast corner of the map. Then, talk to the scholar wearing the Falcon badge in the camp to trigger the hidden plot about the broken map. Regarding the puzzles, successfully solving them will grant you ancient essences, which can be used to enhance your equipment.

How do you pass through the Hidden Village in Underground Castle 4? Actually, the Hidden Village is a high-difficulty secret realm. It's suggested that players prepare high-speed attack equipment in advance and reasonably match the team's skills to face different challenges. However, if you want to explore first, follow the steps above to meet the basic prerequisite conditions, and finally defeat the boss.
