There are four happy occasions in one's life: rain after a drought, meeting an old friend in a foreign place, one's wedding night, and getting the top score in an imperial exam!
Jiang Yi had many women by his side, but he had never married one of them, much less consummated his marriage with any of them. This time, he was being forced to consummate his marriage with his new wives by a couple of old folks. He knew that the Buddha Thearch had his own interests at heart: the stronger Jiang Yi was, the safer everyone would feel, and the higher their chances of getting out alive and emerging victorious in the battle outside.
Since Yi Chan had no objections, Jiang Yi had no reason to remain stubborn. He bathed and changed into some new clothes. With everyone else as their witnesses, he married Yi Chan and Yin Ruobing, who were both dressed in red.
