Create a highly realistic Hell Gate CG scene. The city gate is huge and ancient, Made of rusty metal，with complex, Dark red and black corrosion pattern. The door is heavily stained with blood, jagged claw marks. The top and sides of the door are decorated with grotesque faces and grotesque carvings, Give it a nightmarish look. Lay a thick layer around the door, Swirls and thick smoke obscured visibility. Add flickering flames and irregularly moving shadows to enhance the unsettling atmosphere. The background should be dark, ominous skies，with a distant hint, hell fire. The door opens slowly，make a squeaking sound, A vivid red glow radiates from within. The ground trembles slightly
