Which episode is Shu Jingrong wearing red in the snow?

From the 12th episode of "Tingxue Tower".

Shu Jingrong blamed herself, thinking that Qing Lan and Bai Di died because of her. Shu Jingrong would rather die than her. Xiao Yiqing persuaded Shu Jingrong that if she continued to be depressed like this, Qing Lan and Bai Di would die in vain. Shu Jingrong told Xiao Yiqing that today was the last day for her to summon the souls of Bai Di and Qing Lan. According to the rules, it takes seven days to summon the souls.

Chi Xiaomo brought wine to Qingyu, but Qingyu looked sad and said nothing. Qingyu and Shu Jingrong met each other for seven days to summon the souls of Qing Lan and Bai Di. The two of them had a lot of worries, so they discussed that they might feel more comfortable doing the soul summoning separately today.

Chi Xiaotai told Qingyu that if anything happened in the future, he could go to Xuegu. Qingyu recalled Bai Emperor with a wry smile. Although Bai Emperor always said that he would punish him, when he actually made a mistake, Bai Emperor would always Tolerance and letting go never really punish, which makes Qingyu feel even sadder. Chi Xiao Tai remembered the last time he complained to Bai Emperor, but Bai Emperor allowed Qing Yu to kill Chi Xiao Tai's army, which showed how much he allowed his apprentice to misbehave.
