• To complete the Travel Journal you will have to use tourist and write 1000 pages in your Travel Journal. It is a special ending.

Tips:
This is hard. So you can start the game with the quest of Followers of Force Knight.

• Within the quest of Followers of Force Knight, Dark Lord will not appear , which means you have a chance to get through this challenge safer.

• Once you clear the game in 5 different campaign worlds and other quests under the castle renovation tab, you can place 'Dimensional Wiseman' in the Castle. He can lead the way to demisional passageway.When recived the quest of Dimensional Wise man ,keep the Dark Lord alive and finally you could enter demisional passageway. The end of demisional passageway is 3000km.
  
• Tips:You can recruit Dark Lord before entering dimensional passageway.Just prepare a Buddy Tablets and some Holy Weapons in Vault.
  
• 完成五个不同次元以及其他城堡界面的任务进度条中显示的任务以后可以在城堡中添加次元智者NPC，在游戏刚开始时和他对话并在后来遇到他时有足够的次元金币就能进入次元回廊。次元回廊的总长是3000km，与达到次元回廊尽头的成就有关。进入次元回廊之前不能干掉魔王否则会进入击败魔王的结局。可以在进入次元回廊之前把魔王妹纸拉进队伍

The Darkness That Was Driven Away

• In order to get this epilogue , make sure you have the 'parchument of darkness'(image below) in your inventory

• 这个结局需要如图的物品(我从次元回廊2800+KM左右的地上捡的，这个东西大概需要在次元回廊才能获得)结局达成条件如下：
  1、跟狼女有过3次以上好感对话（就是获得2瓶友好药水）
  2、在狼女变成狼之前打败魔王
  3、打败魔王的时候物品栏中必须有黑暗卷轴(Parchument of Darkness)

'Parchument of Darkness' can be picked up from ground in demensional passageway, I got one at 2800+KM when walking in demensional passageway and save it in Vault
