In 1879 AD, the roar of steam and steel echoed through London. After the Great Advent, everyone will receive a destiny pocket watch on their sixteenth birthday and open a live broadcast channel - all upgrades and battles will be broadcast live worldwide. Renn Stone, a low-level treasure appraiser from the East End Almshouse, faced his first upgraded trial today. The live broadcast started, and tens of thousands of viewers poured in, waiting to see this poor boy's joke. As long as the trial fails, he will be erased from existence and become the echo of London in the mirror, no one will remember it. But the pocket watch on his chest hides a secret - simulation deduction. Before going to the trial stand, he had performed it 47 times. The judge took out a cursed pocket watch that was said to be able to devour souls, causing an uproar in the audience. But Ren chuckled: "This watch is fake." Before he finished speaking, he revealed the maker's mark hidden on the dial, directly slapping authority in the face. However, the truth is corrosive. When he identified the true history behind the pocket watch, the entire courtroom began to shake - the rules themselves were activated to eliminate this treasure appraiser who knew too much. Renne must make another comeback in the live broadcast, use deduction to find loopholes in the rules, and at the same time deal with the secret calculations from the Eternal Parliament. Tonight, he wants everyone to understand that the people at the bottom cannot kneel on their knees. Moreover, he must personally uncover the truth that had been covered up for ten years.
