Chapter 73 The Oxford Scholar's Conundrum
The Oxford scholar, who carried 20 volumes of Aristotle with him, posed a conundrum to his fellows, saying:

"For some reason, I have been thinking about the use of magical charms to ward off plagues and other evils. This extremely mysterious object is related to the magic square. But the little problem I invented last night will not be too much to you. Big difficulty. However, this question does not require much patience."

Next, the scholar took out a square.He asked people to cut along a straight line, divide into four pieces, and put them back together again to get the correct magic square, where the sum of each row, each column, and the two diagonals is equal to 34.
