Kapitel 664: Chapter 646: Code 210

February 14, Yushu No.1 Base.

The Moon is a lonely planet, its color always a monotonous gray-white, never experiencing the changing seasons like Earth, nor does it witness the alternating colors of nature in all their variety.

Its interior has cooled almost completely, so there's no active magma to drive the movement of the crust.

Gravel from a hundred million years ago will still be here in another hundred million years unless displaced by a meteorite's collision.

But those occasional visitors from outer space are meaningless apart from adding a few insignificant scars, merely brief interludes in billions of years.

From the day primitive humans first saw the Moon until the numerous manned lunar missions, the Moon actually remained unchanged.

Even though there are tens of thousands of people bustling on Earth, the number of humans active on the Moon at any one time has never exceeded ten, and the total number of visits has not surpassed a hundred times.
