When Lu Ming touches the evidence, he can see the "upstream and downstream evidence" related to the evidence - not the content of the evidence itself, but the "connections" between the evidence and other evidence in the process of being produced, collected, circulated and used in the case. What he saw was not a picture, but a chain, a complete chain composed of countless evidence nodes from the incident to the verdict. When a piece of evidence is false, manufactured, or replaced, there will be breaks, dislocations, and distortions in the chain.
