Time Travel, Everyone Died That Year!

A conspiracy-led time travel has forever frozen the lives of a group of young people in a moment of despair. Under this cruel rule controlled by the order hierarchy. Yang Fan experienced the bloody baptism of "Killing Days" again and again, killing every leader with his own hands. Finally, holding a long knife, he stood in front of his old classmate who was now at the top of the order hierarchy. Before the blade fell, the other party spoke first and said in a calm tone: "I'm a bad person? How can you, as my brother, be any better? Are you right, Yang Fan?" Let's briefly describe the combat power system: Level 0-2, those who are capable can use source power to enhance the system or release source power to fight. You can change professions at level 3. Level 4-5, perfect different professional skills. You can change jobs again at level 6. Level 7-8, improve current professional skills. Level 9 can be basically promoted.
