What Tang Xiao obtained was an evolved version of the "super deduction system". It was not a direct prediction, but a quantum-level, millisecond-level mathematical modeling of the battlefield based on all currently observable physical parameters (wind speed, terrain, enemy firepower points, our number of people, supply status, and even the fatigue level of soldiers, etc.), And deduced the success probability and optimal strategy of various action plans in the next 90 seconds. This is equivalent to his brain becoming a supercomputer, but only for tactical-level games with clear physical parameters. The flaws are: 1) He relies heavily on the accuracy of information. If the enemy uses information deception (such as fake artillery positions), his calculations will arrive at a completely wrong "optimal solution". 2) The ethics, emotions, and high-dimensional strategic values (such as political impact) during the deduction process cannot be quantified by the data model, which leads to a huge gap between him and his comrades when using his abilities. This conflict between "digital rationality" and "human emotion" is the biggest internal contradiction in the book.
