Explain UD's spider flow and its weakness in detail. Help the gods.

There are two kinds of spider streams: technological spider stream and violent spider stream. Spider flow of science and technology: altar → crypt → psychic tower → shop → cemetery → psychic tower → upgrade base. The upgrade base produces some (5~7) spiders at the same time. The advantage is that the technology will not fall behind, and several spiders upgraded for attack and defense are very good both in suppression and MF. The weakness is that there are no soldiers in the early stage, so they can only go out alone and be harassed by the death knight. It is very troublesome to meet HUM who drives MK, ORC who drives BM and NE who drives WD. Violent spider flow: crypt → psychic tower → cemetery → altar → shop → psychic tower. In a book, after seven spiders upgraded their attack and defense, they upgraded their technology and established advanced mineral units. The advantage of this is that the troops in the early stage are very strong, even so strong that they may take away their opponents after a wave of suppression, and the firepower of spiders is very strong. The bad thing is that DK came out late, because the altar is on the fourth floor. Apart from the AC tree stream of NE, I have never seen a race that dared to attack the cemetery with ice towers in the barren land in the early days of TR UD. Dogs come out of people's cellars faster than farmers come out of your base. How dare you do that? Don't bring the way of playing computer to SOLO, just kidding.
