Chapter 138: We need to make money nationally The two merchants came to the stone table in front of Robb and sat down. As soon as they sat down, both of them glanced at the big water tower in Robb's house. Robb looked at the two men's eyes and could not help but be happy, "Why? Do you like my tap water system? " The two merchants nodded, "the last time we visited you, we saw that as long as you twist the tap, clear water will come out. We saw it again just now, and it’s truly a great invention.”
It turned out that the Chapel of Darkness under construction had already gotten a pipe connected to the mayor's water tower and was ready to use water. The mayor is also a clever thief. He charges ordinary townspeople at the price of "twenty copper coins a month," but for "large buildings" such as the dark chapel, he charges them at the price of "two gold coins a month." The reason, of course, is that there are many people living in the chapel, and many people will come to use the public water, so he must charge more. "Mr. Robb, can you teach us how to make this thing called tap water?" The two merchants said respectfully, "if we go back and put this in her Majesty's temporary palace, she will be very happy." Robb smiled and said, "well, let me give you some advice, too. First of all, I have to warn you that it is impossible to rely on one water tower to supply the entire Bright Road. Such a water tower is impossible to implement with current technology. You need to partition the city first." At this point, Robb used the goose feather fan and painted the city on the ground with the fan handle, and then drew several horizontal and vertical lines to cut the city into large pieces. Then he drew a sign saying ‘water tower’ in the center of it all and said with a smile, "first calculate how many people a water tower can supply, and then divide the city into many districts according to the population, and build a water tower in each district."
