If one were to view the Intellectual Sword as a topic, the topic would have far too many starting points, far too many factors, and far too much information. Even just confirming them all would be far too strenuous, not to mention calculating the final outcome.
Chen Changsheng decided that it would impossible for him to perform such calculations, or at least it would impossible to complete one round of calculations in the heat of battle. He even began to doubt that anyone could complete this sort of calculation, except that Su Li's performance in the battle that morning was proof that at least he could do it. Of course, Su Li was no normal man, but if he could do it, perhaps it meant that it was possible.
