Have you heard the story of a mad scientist stranded on an island? Me neither, but if I recall correctly, he goes there and finds himself surrounded by seahorses, you might ask why seahorses? Well because they were all going through some gender/identity crisis and didn't know any better creature to fit their spirits better, anyways the mad scientist aka Alexander Quill finds out about their way of life and childhood problems then he ignores them and does his job which is figuring the secrets of the ocean and the universe.

Long story short, he is no longer with us unfortunately, legend has it that his curiosity got him killed by trying to eat a live octopus, poor man, he was insane after all, you know? 😂

Now what is the point of the story?  It's about the octopus which has his arms all over the EC, that means everything is attached to the head, in our case the head is at the start of our target key in hex, for example :
+n target :
-n target :
Now you can do a lot of things with them, like dividing them by any scalar and "adding" or "subtracting" the results to see what happens, maybe drop the first 31 0xf characters and do the /, +, -. Again to see the results all in hexadecimal mod n. Drop 25 0xfs and try again, or try changing the last character of +n target to 1, 2, 3 etc.  Then try dividing by secp256k1 -n/2 - 6 as starting range of division and +n/2 + 6 as end range increment by 1.

Check them all, compare them all, try it with unknown points following the same steps.  Remember N is a fixed value, you just need to find it's weakest points.

Ps, when you managed to crack a key, remember this, don't make a scene by attacking people's coins, you can live undiscovered by using puzzle keys alone, if you go after the coins which are not yours, you will have to live in fear for the rest of your life.  Don't worry about missing out, our beloved dragon will top up new keys for you.😉😘
