Chapter 485 (1/2)

Because of the existence of magic, many times the defense system of architecture must take it into account.

The commanding Office of olu city covers a large area, and it also has another name - inner city.

The gate of the inner city occupies nearly a whole street, and a moat with a width of 5-6 meters has been excavated on the other three outer walls. Not to mention the various sentinel towers in the city, just the arrow tower on the edge of the wall will be set up for hundreds of steps. If one day olu city is really captured, the inner city will be able to hold on for a long time.

The inner city itself is divided into the front yard and the back yard.

Naturally, the front yard is the base of many official departments of the alliance, while the back yard is the office and residence of Tang De.

For the ”transmission” this kind of five ring magic, the commanding mansion building complex was considered at the beginning of the design.

Not to mention the ”flying technique” from the sky, the ”stone walking technique” coming from the tunnel, as well as various ”probing techniques”, ”Eagle Eye technique” and ”sharp ear technique” to guard against secret theft.

The only defense against magic is the contradiction between the duration of the spell, the scope of action, and the difficulty of maintenance.

It is like the solid wood floor at home, sometimes because of the cost of the choice, only installed in the bedroom and even the master bedroom.

The Northern Alliance has been operating for many years, but it is not that it can not be realized. It is based on the simple cost-effectiveness problem, and has different emphasis on the deployment of the whole commanding government.

The most critical primary defense areas, such as the office areas of key departments and the commanding houses, are naturally the means to prohibit transmission and discovery.
