I don't really understand the ending

Hello, allow me to explain a bit about the ending part.

The main plot is about surviving inside the virtual game. Once they install and log on the game, the automatically lived inside the game until they suceeded and survived the game.

Ruam Lanzhu is an NPC that created by Gao Dawei to assist Ling Jiushi to survive inside the game.

The main purpose of their journey is to purify the game because it has been used to control people and caused so many deaths.

At the ending, Ruan Lanzhu and Ling Jiushi finally managed to survived and reached the last door [12th door]

The last door only can be activated by Ruan Lanzhu because he is the 'key' or we can say the 'program' that needed to purify the game.

After the game was purified, everything returned to the normal world before the game exist. Everyone didn't retain the memory of their life inside the virtual game world [except Ling Jiushi].

Ling Jiushi felt devastated of losing Ruan Lanzhu and his Obsidian family, he then worked hard to rebuild the Spiritual Realm.

It took him 50 years to create everything and everyone [in a form of NPC] back inside the Spiritual Realm.

When he finally made it, he decided that he wanted to leave his real world and spend the rest of his life inside The Spiritual Realm that he had created, to live with his Ruan Lanzhu and Obsidian Family.

I think that's the ending based in my own interpretation. Hope it can help you to understand the ending and the series in general.

Thank you
