The White Dragon-sama rejected my worry.
“The Great Water Spirit Undine that serves the Spirit User-kun sleeping there can destroy a country on its own. With the five Great Spirits that showed up at Laberintos…if they were to get serious, they could sink the continent.” (Mel)
“N-No way… Haha.” (Anna)
there are also many instances where Spirit Magic had been shown capable of doing such destruction like The stopping of meteor and summon of many comets including the giant comet. As such the statement above are very liable to be use.
From that statement, I try to find the how much power can be derived from at least 2 millions Undines that Makoto summon during last Arc.
First, let’s go with the lowest interpretation. By considering country there mean (baseline) low 6-B (Low-Country level)
so, 1 Undine = (4.184 x 10^21) J
2 million Undines = 8.368 x 10^27J or 450.958 times above High 6-A (Multi-continental level)
now, let’s treat country as baseline country level.
so, 1 Undine = 2.9288 x 10^22 J
2 millions Undines = 5.8576 x 10^28J or 3156.708 times above baseline High 6-A (Multi-continental level)
now, treat the country refer to Large country level
So, 1 Undine = 4.184 x 10^23 J
2 millions Undines = 8.368 x 10^29J or 6.7484 times above baseline 5-C (Moon level)
Now let reverse calculate by taking 5 Undines = (baseline) Continent level = 3.17984 x 10^24J
so, 1 Undines = 6.35978 x 10^23 J
2 millions Undines = 1.271936 x 10^30J or 10.2575 times above baseline 5-C (Moon level)
Editted: Do we allow this kind of calculation translate directly to Ap?
