This is a memory deeply engraved in Luo Di's mind, hard to erase and intentionally avoided.
Even if he completely comes to terms with his family's matters, he cannot come to terms with this event.
Gao Yuxuan's death perhaps could have been avoided, perhaps back then he just needed to stop the other's solo action, but Luo Di didn't dare to think about it in detail.
As long as he delves into it, death becomes inevitable, requiring that 'show' to create the current Luo Di.
The Squad Leader had to pretend to decapitate Gao Yuxuan to thoroughly stir Luo Di's emotions, making it possible for him to connect with Hell and survive in the extremely dangerous fissure environment.
Therefore,
Luo Di never dared to think about it deeply, he could only bury this matter profoundly, even using techniques from the Game Brain acquired in Hell to deeply shield it.
Whether in usual associations or in most of his dreams, Gao's figure no longer appears.
