The Eldest Lady from a Top Aristocratic Family, with the Support of the Whole Family, Who Dares to Touch Her?

[Big heroine + top hidden family + system + no CP + loyal dog twin brothers + salvation] In the college entrance examination room, Nangong Zhiyou put down the last stroke of the test paper. The voice of the system suddenly sounded in my mind: Countless novel worlds merged chaotically, the male and female protagonists wantonly destroyed and disrupted order, and the entire world of immortality was on the verge of collapse. Tiandao begged her to take action to save the people who were on the verge of destruction. Nangong Zhiyou immediately agreed. The system programmed her origin, (exclusive world = Nangong Zhiyou's exclusive secret realm) and she turned around and was born into the Nangong family, the most reclusive family in the world. She was born as the eldest daughter of the entire family, favored by all members, and pampered to the core. He also has a twin brother from the same mother, a soft and cute puppy, and an extremely loyal dog. He only has his sister in his eyes. She will never go east when she says it. If she says a word, he is willing to block all the swords and mountains and seas of fire in the world for her. It is fate that the two of them meet and redeem each other. Along the way to immortality, Nangong Zhiyou continues to grow. Defeat the arrogant and arrogant, tear down the hypocritical mask, defeat powerful enemies in the way, and suppress the male and female protagonists who are out of control and causing chaos; Healing the chaos in troubled times, protecting hundreds of millions of people, on the sacred road full of thorns, killing and singing all the way. Nangong Zhiyou looked at the Nangong family in front of him: Well... No one told these people that they came because of her and were willing to surrender to her. From being a visitor from a foreign land chosen by fate to being destined to save the whole world of immortality, it is also a fateful reunion.
