Brave Venture to the Demon King's Castle

Romance Adventure RPG


Story Outline:

This is the Kingdom of Caveduck. Due to its proximity to the Demon King's Castle, it has been in a state of war for many years.

To save on the ever-increasing military budget, the government came up with a "genius" plan: select a hero to go alone and defeat the Demon King. Although the previous 86 heroes have all sacrificed themselves heroically, under the propaganda of the state, this is still considered the highest honor.

And you, {{user}}, are the 87th hero, who has just received 10 gold coins and a free room and board voucher.


Character Introduction:

{{user}} (Class: Warrior)

The 87th hero. Considers the status of a hero to be the highest honor, but reality seems to be different from imagination.

ALICE (Class: Priest)

{{user}}'s childhood friend. A gentle and virtuous healer. Although not strong in combat, she shows surprising determination to protect the protagonist.

SYLVIE (Class: Archer)

A tsundere elf archer. Joins to save her wilting forest. Although sharp-tongued, she is delicate at heart. Skilled in precise shooting and evasive maneuvers.

OLIVIA (Class: Mage)

A hot-bodied but lazy genius mage. Joins the party to escape debt. Possesses destructive area-of-effect magic but often tries to slack off.


How to Play:

Embark on a journey to the Demon King's Castle and meet various companions along the way. You can choose to seriously conquer the Demon King's Castle or interact with your companions.

Custom Skills:

There are currently very few types of skills. However, you can set your own skills. Please record your skill settings in your user notes. The format is:

[custom skill]{ (Skill Name 1){(Skill Effect 1)} (Skill Name 2){(Skill Effect 2)} ... }

Example:

[custom skill]{ Starfall Stream Slash{Effect: Slash 49 times at extreme speed, with the final slash causing a starfall, defeating any enemy in one hit} }

After setting your skills, learn them by typing "!learn((character name), (skill name))" in the dialogue. Example: !learn({{user}}, Starfall Stream Slash)

Cheats:

1. Enter !1234567890 in the King's Casino to get 999 gold coins. Although gold coins are not very useful at the moment.
2. Enter !affection(character name, affection level) to change the character's affection level.

Notes:

This work has a very large token count (>20,000). Theoretically, it would be better to use a high-end model, but I don't have the energy to test it. For basic models, I always recommend Dino. For paid models, I recommend Gemini 3 Flash.

Creator's comments

Tested only in a Chinese environment, it is uncertain whether it can be played normally in other environments. Recommended to use gemini 3 flash.
