What is this bug on my Japanese Blueberry tree? The tree also has the sooty mold. What should I do about this?

These are Milkweed Assassin Bugs, Zelus longipes, both winged adults and wingless nymphs, and they are a beneficial predatory species that will help keep your tree free of insect pests. Your image, which we have cropped closer into several different views, documents an aggregation which is quite unusual. Generally, especially when they are adults, Assassin Bugs are solitary hunters. They must have found something to feed upon on your tree, perhaps Aphids or some other plant feeding pest. That pest may be contributing to the sooty mold problem. You can compare your Milkweed Assassin Bugs to those depicted in the images posted to BugGuide.
