As stated in the Ancient Script found in "The Supreme Ultimate"... 5 Mighty GEOplanets will be awaken when our Cosmos faces imminent danger. And since Wu Ji's recent appearance, it has begun to disrupt the balance of the 5 energies. And if Wu Ji is not stopped in time, all existence will be suck into the nothingness. You'll need to find the 5 Mighty GEOplanets to unlock the location of the Gateway, and through those gates, you will find the means to save our Universe before all is too late.
This cache will reveal the Yellow planet, often known as "the Ringed One". This GEOplanet absorbs EARTH energy in our Universe and emits a bright Yellow color in the Ultimate darkness. The "Maternal" Earth energy is one that harmonizes the 4 other forces, and the only energy that found a perfect balance between the Yin the Yang. It is said to be the driving force that keeps the other planets in place and prevent them from drifting away into the abyss. My Fellow GEOmancy apprentices, finding the Earth Planet is crucial to stop Wu Ji... Do not fail humanity's last hope!
Fellow Geomancers are recommended to find the Supreme Ultimate first...
**Spoilers & Clues beyond this point**
Aside from you GEOmancy journey, you may ask why the EARTH element cache is placed here. Well, this location is selected because this location is the very edge of Singapore's "land" or "earth"...at least in the early 1960s. Many of us know that Singapore had undergone a fair bit of aesthetic surgery on the map. But how many of us still remember how the "Original" Singapore looks like? And how many of us know where exactly is Singapore's original soil (unreclaimed), and how massively Singapore have reclaimed our land space in the 1970s until current times. Allow me to give you a quick refresher...
This is Singapore in the 1890s, when we are still under British Empire. There is no Tuas, no Pasir Ris, no Marina Bay, no Marina South, no Keppel and Kallang is just a Basin. Many believe that Land reclamation have already been done prior by the British Empire.
On the final GZ, if you look towards the bearing of 81.0 Degrees and turn about 90degrees to left and right, you should be looking at vast Singapore Straits and ocean, with many trade ships sailing in and out of this spectacular trading heart of many shipping routes. Everything spanning from the Suntec City, Esplanade, Marina Bay and Marina Bay Financial Centre, all.... ALL of these land and buildings should be underwater!! ***Alright, take 5 mins to fathom the massive scale Singapore's transformation. This is a truly remarkable feat we accomplished, raising a magnificent city out from the ocean floor..
