A comic macro will help you build a bridge out of thin air.
To activate the macro, stand on the edge of the block and release the Shift key, taking a pose to build a bridge.
Then we set up the autoclicker on the right mouse button, turn on the macro and the magic begins! The macro will work until the activating key is released. The speed and accuracy of the bridge construction will depend on the settings of the autoclicker and your skill. Good construction!
