Open ditches and underground ditches were two types of drainage ditches. Open ditches referred to visible drainage ditches, often used in places such as roadsides and stadiums. Water could flow directly into the ditches from various locations. The cover was usually a comb or grill, which could pass water and intercept debris. A hidden ditch was a ditch that guided water below the ground. It was usually used to lay water pipes, electric wires, and other pipes. The cross-section was larger than an open ditch. The cover was usually steel plate or concrete. Water could not flow directly into it, and the cover could not block it. Open ditches were suitable for excavation and helped to discharge surface water, which was beneficial to the regulation of underground water level and soil moisture. The underground ditch could drain water quickly, occupy a small area and have a small amount of earthworks, which was helpful for field machinery operations.
Sure. Once there was a superhero named Aqua Man. He noticed that the city's drains were clogged and it was causing floods. So he used his super strength to unclog the drains. He dove into the sewers and pushed all the debris out of the way, saving the city from the flood.
I'm not entirely sure what 'beauty drain fanfic' specifically refers to. It could potentially be a type of fan - created fictional story where there is some element related to the draining of beauty in a very imaginative or unique context. But without more context, it's difficult to be more precise.
One example could be in a fanfic set in a fictional corporate world. A large company is known for its innovative R & D department. However, due to better offers from a competitor, all the top researchers leave. The fanfic could then explore how the company tries to regain its footing, how the employees left behind feel, and what the competitor does with all the new talent. Another instance might be in a fan - created story about a magical academy. The most powerful and intelligent wizards are being drained away to a mysterious land, and the academy now has to deal with a lack of leadership and knowledge in certain areas.
I'm sorry I can't really give a specific example as it's not a very mainstream concept. However, it could be something like a fanfic based on a popular fairy tale. Say, in a 'Beauty and the Beast' - inspired fanfic, instead of the beast turning into a prince, the beauty of the princess is drained away because of a new dark magic in the story, and she slowly becomes 'ugly' in the eyes of the world, while the beast remains as he is.
I'm not sure specifically which 'ahri drain fanfic' stories are the best. You could try searching on some fanfiction websites like Archive of Our Own. They have a large collection of fanfics and you might find some interesting 'ahri drain' related ones there.
Sure. There was a story where a young boy was playing near a pool drain. His small finger got sucked into it. He screamed in pain as the suction was so strong. It took quite an effort to get his finger out and he had to be treated for a bad bruise.
Since 'beauty drain fanfic' is a rather specific and not - so - mainstream concept, it's hard to point out direct examples. However, in general fanfic related to magical or supernatural themes, one could potentially imagine a story where a witch's envy causes the beauty of a young maiden to drain away gradually. Another could be in a post - apocalyptic fanfic where a strange radiation or virus causes people to lose their physical beauty in a slow and terrifying process. But these are just ideas based on the concept, not actual existing fanfics that I can name.
As for the question of which was better, an open pipe or a hidden pipe, the following conclusions could be drawn: an open pipe and a hidden pipe had their own advantages and disadvantages. The advantage of an open pipe was that it was more convenient to repair, and there was no need to dismantle the walls or floors, saving costs. The advantage of a hidden pipe was that it was more aesthetically pleasing. It could be wrapped with decorative materials and did not need to be cleaned frequently. However, the exposed pipes could easily affect the overall beauty of the bathroom, and once the hidden pipes had problems, they needed to dismantle the walls to repair them, which was very troublesome. In addition, according to the different regions, the north suggested going through the dark tube, while the south could consider going through the open tube. Overall, the choice of open or hidden management should be decided according to individual needs and regional climate conditions.
