Review after class:

Data structure is one of Redis’s most important skills, and he has overcome all kinds of difficulties in order to develop such a powerful mind. But when he was practicing the highest level of mind method, his wife gave birth to his son. Because he was so excited, Redis went crazy and stabbed his wife to death. After waking up, his hair turned white overnight, and at this time he knew that his time was limited and he could not take care of his child for long. So he taught his children how to do internal work. This naturally creates a blockage, which has to be slowly deposited into the child’s body. Because he had hurt his child’s inner organs too hard before, Redis specially invited a doctor to seek treatment. The doctor looked through many ancient medical books, but could not find a suitable book. Therefore, Redis died of despair. It turns out that when Redis died, the doctor sucked out all of his child’s internal forces.
