Qian Country, sandwiched between Liang and Yin Countries, struggled to deal with the concerted attack of the two countries despite having the strongest national power.
Luckily, the past alliances between Liang and Yin Countries were far from being united. Most of the time, Yin Country instigated Liang Country to send troops and then chose to stand by and watch, in hopes of gaining from others' misfortunes after both sides were weakened.
Last year, Liang Country, which had been badly fooled by Yin Country, chose to appease Qian Country by agreeing to a royal marriage between the two countries after once again failing.
Duanmu Yi had expected that Yin Country would not sit idly by. However, it was beyond his expectation that Yin Country, known for its scheming and despicable behaviors, would directly target Qian Country.
