Before taking action, Sergei directly conveyed his intentions to Langya through a letter, striking first and striking hard.
An extremely naive yet arrogant declaration of war, one that would surely infuriate Langya and mobilize his men towards Sergei's coal mine.
In Langya's eyes, Sergei is just a lucky little brat, lacking strength but sitting in a seat that doesn't belong to him.
Relying on servitude to foreign businessmen for mere survival, Langya loathes Sergei but doesn't deem him worthy of personal action.
Upon seeing Sergei's letter, Langya knew he had to personally clean up this mess, or else he would lose respect in the Underworld.
On the other side, the head of the mining district, Tretov, saw Langya leading his team away and was utterly baffled, as he himself was ready for a mutual destruction.
It seemed that the other side must have run into some trouble, and Tretov immediately followed quietly with his team, not wanting to miss out on a good opportunity.
