After waking up from a temporary blackout, Voldemort ordered narcissa malfoy to confirm Harry's death. Narcissa found that Harry was still alive during the autopsy, but she hid the truth from her son Draco out of selfishness and reported that Harry was dead.
Voldemort mistakenly believes that his greatest threat has been eliminated. In ecstasy, he forced rubeus hagrid to bring Harry's "corpse" back to Hogwarts for public display, and commanded the Death Eaters to March into Hogwarts Castle in a big way, demanding that all the defenders surrender. When neville longbottom openly refused to surrender and tried to fight back, Voldemort set sorting hat on fire in order to make an example, and put a whole body binding spell on Neville's head.
At this time, the Centaurs who supported Hogwarts arrived. Neville took advantage of the chaos to break free from the whole body bondage curse, drew Gryffindor sword from the burning sorting hat to behead Nagini the serpent, and destroyed Voldemort's last horcrux.
Angry Voldemort tried to kill Neville, but Harry, wearing an invisibility cloak, cast an armored spell and intercepted all Voldemort's spells. Voldemort was then besieged by Horace Lagerhorn, Minerva McGonagall and Kingsley Shackleport.
By this time, Voldemort's army had begun to show signs of rout, and the death eaters were knocked down one by one. When the last Death Eater, bellatrix lestrange, was shot by Molly Weasley, Voldemort was so angry that he tried to kill Molly. At this time, Harry appeared, stopped attacking and started the final decisive battle with Voldemort.
In the confrontation, Harry explained why he survived and pointed out that elder wand was not loyal to Voldemort. Voldemort refused to believe and cast a deadly spell on Harry, who responded with his usual disarming spell. Because elder wand is loyal to Harry and won't hurt his master, Voldemort's killing curse is directly bounced off and hit Voldemort himself.
Because all horcruxes were destroyed, Voldemort was completely killed in an instant, and dark wizard, the most dangerous and powerful man in history, also died under his own spell. After Voldemort died, his body was moved to a room outside the auditorium. And his broken soul will always be trapped in a dreamland, neither dead nor a ghost.

1945 After graduation, tom riddle originally wanted to be a defense against the dark arts teacher at Hogwarts School of Witchcraft and Wizardry, and applied to the school, but was declined by Armando Dippet, the principal at that time, on the grounds of "insufficient age" (in fact, it was the result of albus dumbledore's persistent opposition behind the scenes).
After being refused employment, the unemployed Tom made a special trip to Albania, found Ravenclaw's crown according to the clues provided by Ms. Gray, and made it into his third horcrux by murdering a muggle farmer there. After returning to England, Tom was invited by the Ministry of Magic many times, but he unexpectedly chose to work in the Jimbo-Bok Dark Magic Store.
The reason is that he thinks it is more convenient to find precious collections there as horcruxes. While working in Jinbo-Bok, Tom got to know Hepzba Smith, a client with deep pockets, and learned that there were two treasures in Smith's family-a gold box in salazar slytherin and a gold cup in helga hufflepuff. Tom had the idea of suicide, found an opportunity to go to Smith's house and poisoned Herzba.
At the same time, they stole these two treasures, and like Morfin, they modified the memory of Qi Hao, a house elf in Herzba, making her mistakenly think that she had poisoned the hostess's dinner and let her take the blame. Qi Hao finally died in Azkaban prison. By murdering Herzba Smith and a muggle tramp, Tom made two treasures into the fourth and fifth horcruxes respectively.
After this incident, tom riddle quit her job as Kimble Bok and disappeared for ten years. During this period, he traveled around, made friends with other dark wizard, and further studied dark magic. Because of too much contact with horcruxes, he began to change beyond recognition, so that people could no longer recognize the excellent and handsome boy and began to use the name "Voldemort" publicly.
Ten years later, he returned to the Jianghu and applied to be a defense against the dark arts teacher at Hogwarts again-his real intention was to continue to explore the secrets of Hogwarts and recruit followers among students, and he wanted to make the sword of Godric Gryffindor into the sixth horcrux. However, Dumbledore, who had long been wary of tom riddle's words and deeds, succeeded in becoming the headmaster of Hogwarts.
Rejected his application again. Voldemort bears a grudge for this, secretly cursing the post of defense against the dark arts teacher, so that all professors engaged in this subject will be unable to serve for more than one year for various unfortunate reasons.
At the same time, Voldemort took advantage of this opportunity to go to Hogwarts to secretly hide his third horcrux, the Ravenclaw Crown, in the room of requirement on the eighth floor of the castle, because he thought that no one could find this secret room except himself, and hiding the horcrux here would always prevent others from finding it.
