FC's Three Kingdoms Overlord Continent strategy problem. A chain of attacks and an ambush from all sides, how much intelligence did it take to have such a scheme?

The serial and ten-sided ambush were famous strategies proposed by Zhuge Liang, a general under Liu Bei during the Three Kingdoms period. They required a certain level of intelligence to implement. The serial strategy referred to trapping the enemy with multiple traps to force them to surrender. This strategy required the general to have a high level of strategic planning and command ability to accurately determine the enemy's position and actions, choose the appropriate traps and attack points to weaken the enemy's combat effectiveness to the greatest extent. Ambush on all sides was a more complicated military strategy that could only be realized in a large-scale war. This strategy included a series of ambushes, traps, and attack points aimed at eliminating the enemy in battle. This strategy required the general to have superb tactical command ability, be able to accurately judge the position and situation of the enemy and make a reasonable battle plan, and at the same time maximize the use of terrain and environmental advantages to achieve the ultimate strategic goal. Therefore, the strategy of a chain and an ambush on all sides required a high level of intelligence from the general. During the Three Kingdoms period, many famous generals had high intelligence, such as Zhuge Liang, Guan Yu, Zhang Fei, etc. They could use their wisdom and strategy to implement these strategies and achieve important victories.
