The short answer is easy: "how to brew" by John Palmer. There is nothing better.
My longer response is:
There is nothing advanced or not about the equipment used to brew. Plastic buckets can be used to make every possible beer. The complexity of a beer is driven mostly by the fermentation regime. Monitoring and controlling temperatures, using wild yeasts and bacteria, secondary and tertiary fermentation withoother ingredients(fruit , vegetables, etc), barrel aging, etc.
Second, an advanced or semi-pro brewer would never rely on a single book. There is no person whois an expert on eevery facet of brewing. Any brewer that fits that description will have several books, and probably severalbooks on each topic.
Finally, becoming an "advanced" brewer is a process and a journey of experience. Brewing lots and lots of beers. Making lots of mistakes and learning from everything. Brewing the same beer over and over until it tastes the same every single time. Brewing experimental beers with only a single ingredient change... And comparing the results. Don thesame thing with the same rrecipe, but make a process change. This experience can't be learned by reading. It is sensory training.
Even the most "complex" parts of brewing are pretty simple. It's having the innate understanding in your taste buds that really makes an advanced brewer.
