Nine Hundred Years of Swordsmanship

In the space station, a huge celestial body detection signal suddenly appeared next to Yinghuo's orbit. No one knows when that huge star ring appeared. Compared with the star ring, the spacecraft that went to explore it was like a grain of rice dropped into the pot. This is a ruined fragment of a continent. After fifty years of excavation and exploration, human technology and civilization have reached unprecedented heights. Deep in the dilapidated ruins, there is a line of words written on a broken stele: Everything behind the door cannot be looked at directly, cannot be described, and cannot be defined. Facing the giant golden door imprinted on the ground, people have exhausted all technological means, but they can't leave the slightest trace on it. After clearing out the entire door, people were horrified to find that the door was covered with dense fist prints. At the bottom of the giant door, there was a line of handwriting written with fingers: I am at the gate, and I will not spare anyone.
