The protagonist was captured by aliens on the way to buy cigarettes at night for experiments, but because the spacecraft malfunctioned, he could not return to Earth.

I recommend the following fantasy novels where the protagonist is captured by aliens for experiments: "The Strongest Overlord of the Galaxy","Legend of the War Witch","The Path to Protagonist Cultivation","The Rise of a Failed Civilization","The Night of Online Games","The Red Night Summoner","The Earthlings Are More Ruthless","The World I Live In Can't Be An Experiment". I hope you like my recommendation. Muah ~ If you need anything, feel free to consult me.😗

Do you recommend the " Alien "was a sci-fi futuristic novel. The plot matched the description. The main character, Luqiao, was an alien visa officer. After doing experiments, he became more handsome and reached the peak of his life. I hope you like this fairy's recommendation. Muah ~😗

The science-fiction super-tech novel,"Lord God's Experimentals," might be suitable for you. The plot of the novel was about a male protagonist trapped in a decadent society who suddenly had a mysterious mission panel and was brought to a new world. The people there had all kinds of amazing superpowers, and the male protagonist was an experimental subject. He was used in all kinds of dangerous experiments with other experimental subjects. His only way out was to grow and eventually escape. I hope you like this fairy's recommendation. Muah ~😗

This was the plot of a fantasy novel. A person was captured by aliens and sent to another world, but he could buy a gun at any time. In the other world, this person might encounter all kinds of challenges and dangers, but he also had the opportunity to become a powerful warrior and fight for his freedom. In addition, buying a gun would also add some interest to the story because people in this other world might use all kinds of weapons to protect themselves.

😋According to the plot you provided, I think you might like Doomsday Dragon Tooth, a sci-fi-doomsday crisis novel. The protagonist was under the alien's murderous rule, and finally obtained the experimental liquid that could integrate biological abilities, leading mankind towards a future of resistance against aliens. I hope you like this fairy's recommendation. Muah ~😗

Dragon Ball Ring.

I recommend "Transdimensional Annihilation" to you. The main character of this book, Fan Si, was captured by aliens, modified, and then released back to Earth. I hope you like this fairy's recommendation. Muah ~😗
