When I was digging in the middle of my old earth wall, was Long Mai broken?

The objective fact is:

How many generations have failed to get out of the land of yin houses, just because of "building roads, cutting mountains, digging tunnels, bridging bridges, and building reservoirs" on the Long Mai, these originally poor yin houses have become a treasure trove overnight.

Because they didn't have the idea and theory of "stratum structure and stratum energy accumulation" at that time, because they didn't understand "stratum with oil, stratum with natural gas, stratum with coal, stratum with iron ore and stratum with gold ore?" Of course, they don't understand which class of Long Mai is the pulse gas that affects human destiny, so they have to take a completely conservative way to protect it, that is, Long Mai can't be dug, and digging Long Mai is equivalent to digging pulse gas.
