Of course, there's also an element of fantasy in it.
Because what Ji Yuan needs most right now is this item. Once he gathers the Mysterious Ice Fire Lotus and Nine Luminaries Stone, then the [Celestial Craft Square] can be upgraded.
Once this building is upgraded.
He can get an extremely powerful Tier Three Array, the [Inverted Big Dipper Formation]. Ji Yuan reckons it's similar to Yun Qianzai's [Inverted Rivers and Lakes Array], both involving a reversal of the Array, enhancing its power while rendering those who enter the Array impossible to trace or break.
Additionally, he can obtain the Purple Mist Stone.
Ji Yuan has almost collected all the other sword refining materials, the only thing missing is this Purple Mist Stone.
Once he obtains the Purple Mist Stone, he can proceed to refine the Canglan Sword.
If it weren't for the Mountain of Mind and Heart, the Canglan Sword would have been Ji Yuan's Lifebound Magical Treasure.
