There were many novels that described the protagonist obtaining alien technology, such as the " Three-Body " series, the " Galaxy Empire " series, and so on. The protagonists of these novels often faced huge challenges and needed to use alien technology to improve their abilities and constantly explore the secrets of alien civilizations. These novels often involved alien creatures, interstellar travel, cosmic physics, and other aspects of knowledge that shocked and curious readers.
I'm not sure which novel you're referring to. However, if you are referring to the " Three-Body " series of novels, you can refer to the following plot:
In the " Three-Body Problem " series, Chinese scientist Ye Wenjie accidentally discovered a technology that could control the power of the universe while researching alien technology and brought it back to China. This technology had greatly improved China's scientific and technological level, making it a powerful country in science and technology. However, due to the terrifying power of this technology, Ye Wenjie and others had to hide it and have been trying to find a way to limit its use.
Another option is to start from the kidnapper's perspective. Show their planning and motives for kidnapping Allen. It gives a different view and hooks the reader as they wonder why this is happening to Allen.
After the protagonist obtained the alien technology, he established a country on Earth with powerful technology. He used alien technology to develop many advanced weapons and equipment to help the Earth army defeat the foreign invaders.
The protagonist also used alien technology to build a science and technology museum to display the various technologies discovered by the Earthlings in the alien civilization to show the strength of Earth's technology to the outside world.
As time passed, the protagonist gradually obtained more and more alien technology, and his country became more and more powerful. He began to explore the alien world in search of more alien technological resources.
In his exploration, the protagonist encountered some difficulties and challenges, but he always insisted on his dream and tried to make his country stronger. In the end, the protagonist successfully explored more alien technology and brought it back to Earth to share with the people of the world.
The protagonist became a great leader and his country became a prosperous and technologically advanced country.
One possible plot could be that Allen is a curious character who was exploring an old haunted house. His tiki ghost hand, which has a mind of its own, reaches out to touch an ancient door. As it tries to pass through the door, it gets stuck. Allen then has to figure out a way to free it, perhaps by using some magic spells he learned from a local witch.
One possible scenario could be that Barry gets hurt during a fight with a powerful meta - human. Maybe the meta - human has some sort of energy - based attack that Barry can't dodge in time, and he gets severely injured. Another scenario might be that he gets hurt while trying to save someone from a dangerous situation, like a collapsing building or a runaway vehicle. In some fanfictions, he could also get hurt due to some sort of betrayal within his team, where someone accidentally or purposefully sets him up to be attacked.
Perhaps in the fanfiction, the Tiki hand getting stuck is a sign of some sort of magic at work. Maybe the door is enchanted, and the only way to free the hand is to solve a riddle or perform a specific task. This could lead to an adventure for Allen as he tries to figure out how to free his hand.
