Sen no Rikyu was a Japanese tea master who was forced to commit ritual suicide in 1591 by the then emperor Toyotomi Hideyoshi. Rikyu was well known for refining chanoyu, a popular Japanese tea ceremony and inventing a two-tatami mat tea room named Taian, which is now at Myōkian temple in Yamazaki.
What makes this seed so creepy is the fact that this man's name when used as a seed spawns you right next to a jungle temple. After you spawn look to your left and there it is. Makes me think of the tea room he had his last tea ceremony in right before he killed himself in it.
Well when i done blood moon seed on Minecraft I saw the white moon in the Maddle of is hole the seeds is Saturn. You can try it you self well I did wait for 5 night that when I saw the moon hole in the maddle
Given the seed you provided, the Biome you have spawned in has lots of rocks that are + or plus shaped, the trees may spawn every now and then and be a slightly thicker cross, but to be honest due to the size of an infinite world regardless of any seed you use and the amount of blocks that are already in the game, be expected to see Millions of crosses if you really explore and pay attention! To date I have found a cross on nearly all seeds I have played on, and it's not sheer luck, it's how the terrain generation mixes up stuff! when you find veins of Iron, Gold, Diamond etc. there is always gonna be a chance those can be in a shape of a cross! People don't usually notice because they pick apart them block by block and digging blocks around it to make sure there is no more! The game is Huge, every seed you pick is gonna have Millions spread across the 100,000,000 by 100,000,000 by 50-100 or more blocks in each category! And because there is that many blocks in game also expect to see squares and rectangles and a blocky type circle or oval the blocks make as well, I see stuff like this all the time! The only way to prevent it from happening is by coding in complex math to if blocks are next to each other to offset blocks and such, and Mojang / Microsoft is not gonna do such measures! The cross or any other shape is here to stay
And last note because the Game if set on infinite is so vast, you will indeed find every biome including all the rare ones in game, regardless of seed you will always find all Biomes in a 25,000 by 25,000 block grid but lately with new biomes added the grid might be smaller since generation has changed, so you might find everything in a 10,000 by 10,000 grid these days! The only time you will find seeds that don't have all biomes in it is if you done a Custom Preset and removed stuff purposely out of it kinda thing but even if there is the odd seed you can't Find it in a 25,000 by 25,000 grid, you will surely find what your looking for within a 100,000,000 by 100,000,000 area, the key is just go exploring and you will find repeat structures etc. The loot may be different each time but that's a whole another algorithm! The chances of finding a seed that is Missing a Biome or More would be very rare to find simply due to the sheer size that an Infinite world size is!
Actually, the world border is at 3mil - 30mil (i cant remember which ) as its not possible for it to be infinite. So they set up a border most would never see. this border was discovered on anarchy servers such as Anarchy.pw or 2b2t, being popular servers, and being up for so long someone was bound to find the world border. however this entire 3-30mil world would be required to be stored in a huge terabyte file. so dont expect to be seeing the world border anytime soon unless you watch some youtube.
I have teleported to the world border before, New update Aquatic Snapshots removes the Farlands, and when you pass through it, it just repeats every so Many Million Blocks, another thing is if you affect a block on any area even if your like a Billion blocks away the game now repeats it and all changes happens everywhere onto infinity! Try changing a block at 10,000,000,000, 10,000,000,000 and go to something like 100,000,000,000, 100,000,000,000, you will see the Block or blocks you have changed doesn't get reset! How I found out is I was wanting to make a super secret base that you had to teleport to, but when I teleported further and further out my secret base kept showing up over and over! Thus farlands is removed now and it just repeats over and over now! Thanks to Update Aquatic Snapshots! Kinda disappointed but at same time at least the game wont crash now
