Gentlemen,
I have here a treasure map (part of 3 sets of map) that contain the detailed cross section of the underground (vertical) forteified/concrete structural design of the big volume or Imperial treasure chamber or tunnel...the other two sets of map is the usual vicinity maps...we are not interested to operate these site bcoz its a big volume treasure and very expensive.
I think it was designed and done by " Miyata Engineering battalion" bcoz it was written on its end page ( we let it translated by TH japs)
My suspicion is....IF THE STRUCTURAL DESIGN OF THESE VERTICAL (aprox. 100+ feet deep) CONCRETE/ FORTIEFIED TREASURE TUNNEL AND CHAMBER IS THE SAME OR IN UNIFORM WITH OTHER IMPERIAL TREASURES CHAMBERS....or made by the same Engineering battalion...
THEN IT IS POSSIBLE....THAT THEY HAVE THE SAME ENGINNERING/STRUCTURAL DESIGN OF THE OTHER...IMPERIAL TREASURES CHAMBER SITES.....meaning after 6 DECADES OF TOTAL SECRECY...we finally have an idea how IMPERIAL TREASURE CHAMBER/TUNNEL DESIGN LOOKS LIKE AND MADE OF....including its sand/water/concrete/mud traps, concrete obstacles/decoys, types of treasure markers ...etc......these maybe the ACHILLES HELL of fortified... Japs Imperial treasure chambers... kaya nga dapat esekreto muna natin ...
Merry Christmas and Happy New Year !!!
