@Sk1d00-Cod33r The origin LiquidBounce's BoostHypixel Mode Fly + 1.39 Timer, bind them on one key
Or you can use blinkfly, bind Hypixel Mode Fly and blink and 2.5 (recommand) timer to one key
Another way is to edit the LiquidBounce because it has opensourced on github XD
There are minceraft versions where you can use cheats to write colored signs or even commands onto signs cause a check is missing.
1.8 -1.8.3 allow for that and also 1.12 as far as I know. But its patched by spigot/bukkit. So it only works on vanilla servers.
And the anticheat thing, although the anticheat is bad, it can still detect you if your settings is too ez to detect (like killaura 7 block range lmfao), or maybe staff banned you but you just don't know that
