It had been a long time since Rui had looked back to the past so deeply. The reason he avoided doing so was not because he was running away from the past.
No.
It was not that he was avoiding the past, it was that he was too focused on the future.
He had a Martial Path to tread. He had a Martial Art to grow. A higher Realm of power beckoned to him. That was why he didn't have time to wallow in the past. of course, he didn't forget it, but it had been a long time since he was immersed in it.
That was why he felt overwhelmed when he revisited his previous life. It made him boundlessly grateful for everything he had in this life.
A healthy body.
An extraordinary mind.
Priceless memories of his previous life which not only contained invaluable knowledge and experience, but also contained the magnum opus of his previous life; the VOID algorithm, and his lifelong ambition that became his Martial Path.
