Yang Yi and Grevatov sat down face to face, while Anton and Tartar continued using binoculars to observe Yarebin's funeral.
Grevatov seemed like a very composed person. Before Yang Yi could ask any questions, he spoke slowly and calmly: "About that graffiti, the reasons are quite complicated. The decision to use a nuclear symbol was because Yarebin didn't have time."
Only Yarebin and a few of his closest associates knew about his physical condition, so Yang Yi understood Yarebin's helplessness. He should have had better options, but time was not on his side.
A hero in his twilight years—that's all there is to it.
