(PS: It was quite a surprise when I woke up today and saw comments criticizing me for updating too much and having too many bursts of releases, which led to some readers dropping the book... I was a bit upset.)
After one year and four months, the construction of the Amazon River mouth dam was complete!
This was the grandest and most magnificent construction project in the history of mankind!
The exact duration was one year, four months, and eight days, involving a total of 33,624,439 workers, countless vehicles, trailers, airplanes, and more. Based on the workforce of over thirty million, nearly five times that number of logistics and related materials manufacturing and transportation personnel were involved. If all of them were to be included, the number of people involved in the project would reach an astonishing one hundred and ninety million!
