watched Shen Teng 's solo walk on the moon today. In the play, Shen Teng thought of an unrestrained "extended day plan" and turned on the life-defying mode. In fact, this plan can also have a vacation mode. The moon's daytime is 14 days (Earth time, which will not be emphasized later), and the daytime can be extended to 41 days by chasing the sun, indicating that the speed of the lunar rover is 0.6585 times the speed of the moon's equatorial rotation line, and a day and night of the moon is 28 days. After calculating, it takes 42.56 days for the lunar rover to circle the moon. cos48.8º=0.65869, that is to say, if you drive the rover to 48.8º north or south latitude and then chase the sun all the way, the sun will never set, and it takes 42.56*48.8/360=5.76 days to drive to 48.8º north latitude <14天，如果继续往高纬度开就可以实现每天保证8小时睡眠。当车开到宇宙之锤所在经度时把车开到赤道附近取完再开到高纬度，按原来的办法就可以实现度假模式取宇宙之锤了。
