How did Napoleon die? Come on, everybody, 3Q.

1821May 5 17: 49, Napoleon, who was exiled to St. Helena in the South Atlantic, died. The French authorities later claimed that the emperor died of "cardiovascular disease". However, many people believe that the man of the hour who once dominated the European continent was poisoned. Recently, some experts pointed out that Napoleon finally died of stomach cancer. Some experts pointed out that the best way to find out the cause of Napoleon's death is to "open the coffin for autopsy" and conduct "DNA test" on his remains, but this is "completely unacceptable" for many French people. Some relatives of Napoleon think that "the cause of Napoleon's death is not important, because he still has many more important problems to study."
