"你知道吗，别费心展示视频了。我们将制作一段迷你潜艇/舱穿越到第五洞穴的视频，毫无问题。对不起，恋童癖家伙，你真的自找的。"

Simplified Meaning:

Someone is saying that instead of showing an existing video, they will create a new one to demonstrate how their mini-submarine can reach a specific cave. The speaker seems confident in their invention and dismisses the need for proof with an existing video. They also insult someone by calling them a "pedo guy" and imply that this person deserves the criticism. An example to help understand this could be from a school project. Imagine two students arguing about the best way to solve a problem. One student, convinced they have the right solution, decides to create a new demonstration instead of using someone else's. During the argument, they insult the other person, claiming they deserve it because they questioned them. This shows how confident and confrontational the speaker is, and how they prefer showing their own work over relying on others. It also illustrates a more negative side of human behavior, where people can be aggressive and insulting when defending their ideas. For someone applying this in life, it teaches the importance of confidence in your abilities but also reminds us to avoid unnecessary insults. Instead of demeaning others, it’s better to focus on demonstrating your strengths through positive actions.
