Is there a second American film "District 9"?

Right, because it seems to be adapted from a novel, and now it seems that shooting has already started.

Plot: The aliens finally return to their own planet and tell their companions what happened to them and their companions who are still trapped on the earth, and what the earthlings did, so that they can know how violent the earthlings are. The aliens who knew the truth decided to return to the earth three years later, save their compatriots and punish the people on earth. In the meantime, they made all the preparations, and the alien hero fulfilled him. We promised to prepare treatment equipment or medicine, and decided to set off the next day after calculating the time to arrive on Earth exactly three years later. Alien heroes also prepared therapeutic equipment or drugs.

The next guess is that it may be similar to the story of "World War II" and "Independence Day". After the alien hero came to the earth, he struggled to find the infected hero and finally found him, and the companion brought by the alien hero was destroying the earth. All this was seen by the hero, but he couldn't stop it until the alien hero met him again and said that he could be cured and brought to the world. His own planet may be destroyed in such retaliatory sanctions. Of course, the hero can't promise, and he repeatedly shows his attitude. If the alien continues to attack like this, he would rather not treat his infected self. He doesn't want to see the earth destroyed like this, because he is more eager for peace, although he also hates human beings. After being infected, the protagonist is hunted by human beings, and he wants to study him and use him to control alien weapons. But he is still very sensible. She knows that there is only one result of such hostility to each other, that is, the destruction of all living things on the earth, and all civilizations will cease to exist, including, of course, his favorite people, for mankind and for his lover. He refused the treatment of an alien hero and bravely found his lover. When she faced it head-on, the hostess finally knew who had been silently caring for her and sent her flowers ~! She also knows that she still loves this man. Although he is really an ugly alien now, their love finally makes the heroine willing to accept this ugly "alien" with him when the earth is about to be destroyed. I spent my last good time, and this scene happened to be seen by the alien hero, which made him understand that true love is above everything else. After some ideological struggle, I finally agreed to the hero's request not to destroy the earth, and just before the ultimate weapon was about to be launched to destroy the earth, I took the initiative to stand up and stop the start of the ultimate weapon, but I paid the price of an alien hero for it. At the cost of life (it may be accidentally injured by the earth warrior during the period), but it finally prevented the destruction of compatriots. Just before the alien hero died, the hero tried to save him, but the alien hero knew that he was dying. With trembling hands, he took out his own medicine for treating hero variation and died. All the aliens left the earth with the bodies of alien heroes.

After the hero recovered his true colors, he lived happily with the heroine. .....................................
