You'll need a lot of computer power, like a lot of PC's, or else will take years to crack it
Not necessarily; any reasonably modern GPU can brute-force all 281 trillion possible "decoration" seeds within a few hours (the GTX 460 was released over a decade ago, which is ancient by computer hardware standards, and could still do it in about 8 hours):
When this tool was originally developed in early 2014, it could test about 10 billion seed values per second on a GTX 460; a GTX 760 could do ~20 billion values per second, and today a GTX 1070 (or other similar modern GPU) can test about 40 billion seed values per second. That means even with GPUs continuing to get faster and faster, it still should take over 14 years to reverse engineer a Minecraft world seed by trying all 18 quintillion possible values.
But there's a catch.
Minecraft only uses the full 64 bits of the world seed for biome and terrain generation. When choosing locations to put villages, temples and other such features, Minecraft uses the random number generator that comes with the Java language, and that only uses the lower 48 bits of the seed value. That reduces the search space by a factor of over 65 thousand (264 / 248 = 216 = 65536), which reduces the search time from 14 years to about 2 hours.
The only issue with this is that you'll need to search another 65536 seeds (at least) for the correct biome map, which is likely to be much more time-consuming than structure locations, but you can easily minimize false positives by supplying enough structure locations (more will not noticeably affect the search time since as soon as one location fails it can go on to the next seed and the failure rate per location will be very high).
Note that the tool in the link does not include End pillars (and may be outdated), and in any case they don't have enough variation to give meaningful results (there are 10 pillars which only vary in their relative positions, meaning there are only only 3,628,800 possible combinations - that gives an average of 77.5 million 48 bit seeds which will share the same arrangement as another seed).

As far as I know, I5-5000U (0 - I don't know the exact data, U - wwo cores and four threads). He broke the world seed in game, in about 10-20 minutes. If the person breaking the seed did it several times e.g. in singleplayer.

Unfortunately, I only have the coordinates of one (or two) villages, and I will not get the next ones.
To be exact, we have partially overwritten the voxelmap file / folder several times. From it I took everything that I wrote above. I'm sure the seed was randomized, not set
I have data on the height of the end pillars and 16 locations (x, z) of the biome. Can I crack the word seed?
The version is 1.15.2

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
