Harry has entered his second year of study at Hogwarts School of Witchcraft and Wizardry. Just when he was about to return to Hogwarts to continue the magic course, a house elf named Dobby advised him not to return to Hogwarts, which would put him in great danger. And Harry, who wanted to go back to school to be with his friends again, ignored advice and went back to the school where he missed a vacation. He was still so famous in school, still not popular with Professor Snape and other Slytherins, everything was the same as last semester.
But soon something strange happened: the students at Hogwarts were petrified, no one knew what it was, and Harry could always hear a sound, a sound that seemed to come from inside a wall , They are telling a story about the secret room. It is said that this secret room can only be opened by the people of Slytherin. It involves an ancient evil secret, the secret of the young Voldemort.
The celebrity of the wizarding world, Guidro Lockhart, came to Hogwarts as their Defence Against the Dark Arts teacher, and Harry and the others were very excited. Harry accidentally discovered that he could understand the language of the snake, and the snake was the symbol of Slytherin. Everyone wondered if Harry opened the secret room, and this was Slytherin's privilege.
