I'm Back from Eternity

Under the Arctic glacier, there was a corpse frozen here. It had been buried for an unknown number of years. Suddenly, the corpse opened its eyes suddenly, and the ice for dozens of kilometers around it cracked. The man slowly floated upwards. When he returned to the ground, he looked at the surrounding snow indifferently, and walked away step by step until he disappeared into the vast snow. Who is this person? Why is it buried under the Arctic glaciers, and what will happen next, so stay tuned. This novel and its characters are purely fictitious.
