We usually praise Riboku by ranking him as a better general than all the others. But what if his greatest strength lies in having the influence of a prime minister? Generals focus only on the battlefield at hand; they don’t concern themselves with or prepare for everything else. The prime minister views the ENTIRE country as a battlefield.
Examples: 1- Riboku led an army that was far to the north to attack Ousen and Moubu. A general alone would never worry about something so distant, though even so, Ouki sensed something was amiss.
2- Riboku modified the Retsubi fortress before Qin attacked it, making it a fortress difficult to defend.
3- Riboku building a real wall after Bujon and Heiyou, manipulating Ousen and Kanki to go north.
4- Now, the only time someone with just the rank of general thought outside the battlefield: Ousen securing a supply line with Qi via the river during the Western Zhao Invasion Arc.
