What is the highest proficiency level of the six Zhuang villages after tomorrow?

Manor can be upgraded every 5 levels, synchronized with the measurement of less than 8 manors. All the measured values of 6 manors are over 30, which can be upgraded to 7 manors. If some levels are advanced and some are too backward, the highest proficiency level will be stuck at 32 until the manor is upgraded, but there is no level limit after 8 manors.
