About the Land of Dragon Crystal
I checked the information carefully, but the information did not clearly state that the Land of Dragon Crystal was "just formed".
My statement that the dragon crystal land has not yet been formed at this time is mainly because in the plot, after the molten mountain dragon, the grand leader discovered this crystal, and everyone in the investigation team was surprised.
The grand leader has been tracking Nergigante for decades, and it stands to reason that he should have been to the Dragon Crystal Land, so I think the Dragon Crystal Land has only recently become like that in the MHW plot.
But the two points mentioned by book friends are very reasonable. One is that the scale of those crystals does not seem to be formed in a short period of time, and the other is that Fat Man eats crystals. (Especially the latter one, it is very clear in the ecology)
Taking the rationality into consideration, I will revise the follow-up.
Modified Jackie Chan's crystallization site already exists, but it is located in the core area where ancient dragons are densest and most dangerous. The environment is very closed. At this time, no one from the investigation team has arrived. It is a geological change caused by Laoshan Dragon. After opening a corridor, the head of the regiment was able to arrive.
So no one understands.
At the same time, this kind of crystal also exists in the area outside the Dragon Crystal Land, but it is very fine and not everywhere like the Dragon Crystal Land. (This setting is to give Fat House a way to survive.)
The approaching hatching of the Dark Lantern Dragon egg and the active energy will accelerate the growth of the crystal.
As for why the investigation team failed to connect the fine crystals on the periphery with the large crystals in the Dragon Crystal Land, well, I'm a hen. Just think if you see something the size of a mung bean or a soybean, you will think it is a diamond. If I give you a piece the size of a human head, you will subconsciously think it is something else
