The war between Britannia and France lasted for over a century. The Night Watchman had also experienced it... however, as a king from a much more ancient era, he didn't have much interest in the mutual slaughter between human races.
If I remember correctly, during that period, he was already in the Far East Region, on the one hand to avoid the chaos of war, and on the other to search for the legendary elixir of immortality in the Far East Region.
But he had the right to longevity because of a wish granted by the Magic Lamp... so what about Xie Jiatu?
He certainly wouldn't have wished upon the Magic Lamp... how exactly did he achieve longevity? At this moment, even though the Night Watchman wasn't interested in what Xie Jiatu was trying to accomplish, he was still a bit moved by the fact that Xie Jiatu could live to this day.
