(Repost) [jar Tutorial] 'Remove the Four Default Websites in UC "My Navigation"'

This tutorial is requested by someone, it's quite simple. Actually, I think the main purpose of going to these four default websites is to reduce the size, because the image code for those four navigation links takes up quite a few characters. Taking version 8.3 released on 5.15 as an example: Tool: MT. Search for 'Sina', you get a class called bn.class, search for 'Sina' again, you get a method e()V, go inside, from the third line of iconst_0 all the way to aastore under bipush 23, delete that, then change the first line bipush 24 to bipush 0 (it's okay if you don't change this), save. If you want, go into the constant pool, filter by *, delete the URLs, image codes, and website names of the four websites, save, review, and push it back. No bugs were found.
