In The Long Dark story, one way to melt snow is by finding a heat source like a stove or campfire. Put the snow in a container and place it near the heat. Another option could be using solar energy if it's available.
It's highly unlikely. Second-story windows don't produce the intense heat necessary to melt artificial grass. Also, the materials of windows and artificial grass are not prone to such interaction.
As of now, the Genshin manga is not finished. The story is still evolving and there's more to come for fans to enjoy. The creators are taking their time to develop a rich and engaging narrative.
There's no definite answer yet. It might continue if there's enough demand and the creative team has more story to tell. But it could also stop if they feel they've completed the story arc.
There is a Genshin Impact manga available. It brings the game's world to life on the page with beautiful art and engaging storylines. It's a great companion to the game.
