Ophiuchus Restricted Area

On the day the twelve warriors were thrown into the Crystal Trial Field, the broadcast said there were only two rules. First, crystals are exchanged for one thousand U. S. Dollars. Second, it is limited to seven days. The third unsaid thing is: if you die here, your heartbeat will stop simultaneously in reality. —— Elias is the thirteenth person captured by the system. He shouldn't be here. There is no place for him in the twelfth house. The system gave him four words when entering: hell difficulty, survive alone. Other players use skills to kill people, he uses a scalpel. Other players are grabbing crystals to exchange for money, while he is saving crystals to add to the schedule. While other players were trying their best to get out alive, he was thinking about one thing—— The system made three errors. The first was missing the ceramic scalpel he had sewn under his skin. The second one allowed him to see secret records that he shouldn't have seen. The third... Is that he is still alive. —— As the four teams battled it out in the Endgame Square, Elias stood atop the bell tower. He looked at them the same way he looked at the wounded with ruptured spleens on the operating table in the war zone. Not indifference. It's calculating. Who can be saved? Who is dead. And - who should he save.
