I think what made this so effective in this particular novel is how Yan Hao's achievements in his new life provides such a stark and tragic contrast to his unrealized potential in his previous life, while making it clear that his potential for greatness has always been there. Yan Hao had done so well as a pharmacist in his previous life, unacknowledged and ostracized as he was, and could have done so much more for their world if he continued, and that is just the tragedy of it. Yan Hao isn't doing great in his new life because he is snatching other people's achievements and making it his own, no. He had always done great things, even as a pharmacist, but was unacknowledged and robbed of recognition because no one cared enough to watch out for him or fight for him. As the novel progresses, it becomes very clear that his absence in the pharmaceutical field created missing links that drastically delayed and even all-out hindered the progress that could have been achieved if he was still a pharmacist.

At the same time, you can't help but feel despair for the old timeline which never saw the advancements and developments in mech building that Yan Hao helped to create in the new timeline, and you feel such grief for how the characters that you get to know and love in the new timeline were affected by this absence.

Their romantic storyline is certainly fun to read, lmao. These two basically made their love life into military milestones. Reading military officials bite their tongues and become unwilling third-wheels of their hardcore pseudo-PDA is hilarious because they can't even complain, hahaha. Oh, this custom-made mecha that marks the new age of mecha building? It's my boyfriend's proposal gift to me, tee hee 😂😂. Thinking about how the future students of their federation will have to learn about this part of their history is just hilarious.

I actually prefer how Yan Fei and their parents just gradually fade into obscurity as the story goes on. Not everything needs closure. In a way, their disappearance in the plot is a manifestation of Yan Hao letting the past go and breaking the shackles that used to tie him to them. His world became more than just their unattainable love. Yan Hao would never know if they ever truly regretted their treatment of him. He would never know if they were truly capable of being better for him, of caring for him, or truly loving him. It doesn't matter because they no longer matter to him. They are all in his past.

It was certainly a pleasant surprise when the main antagonist for most of the story gets a redemption plot. Making him have a bottomline that even he wouldn't cross definitely made him more complex and appealing as a character.

Only these two would fly into their own romantic world while everyone is scrambling in shock. Who cares reporting to the military after defeating the zerg king? Let's elope! Lmao
