The journey to Tong'an from Leilani was a cruel one. The distance alone can make one wish they never took it for it was harsh and seemed not to end, Yishen left his kingdom with fifty thousand trained soldiers whom he could trust. He could have took more but he was sure he didn't need that much, after all it was rather very cold in Tong'an at that time of year.
At night, after a long ride they would camp outside and sleep under the stars as they regained their energy to fight, the whole time Qianlong had no idea what was coming to him - it was an ambush.
Wars do really bring out the best and worst in people, but also unusual alliances are always formed during this time. One I didn't expect was of Lee and Yishen, somehow they found themselves bonding over rum or simply telling tales at night.
