Because Lucifer's organization in Russia was aloof and special, it was destined to disrupt the Korean-Chinese Alliance in Russia. Lucifer could only choose to cooperate with Russia's military and powerful nobles.
The situation in Russia was complicated. Although Gu Yuexi was a respectable member of Lucifer, he was regarded as the second-best under Rex, could not compare with Rex's influence in the upper society of Russia, and his authority over Russia's government forces was not as good as Rex's.
Therefore, he went to Russia in place of Si Yiyan, not only responsible for investigating the entire Lucifer operation but also coping with the war between the military and these nobles. Even though Gu Yuexi was superior in intelligence and more capable than most people, he could not help but feel pressured. He had not closed his eyes properly for three days and three nights since the operation began.
