May.
Several years had passed since Li Chengyi arrived in Anze, and the development of Shadow Dragon Prison was finally nearing its final phase.
The so-called eighty-one Dragon Jails had been mostly opened by him by releasing prisoners in the form of his Primordial Spirit.
Now, the development of Dragon Jail was finally coming to an end.
Inside Shadow Dragon Prison.
Gloomy shadows were omnipresent, enveloping everything within the Dragon Jail.
Li Chengyi floated in the darkness, and having spent a long time here, he gradually discerned the entire structure of Dragon Jail.
This place was like a huge cubic Rubik's cube, with each small square being a cell for imprisoning a prisoner.
And he had already explored the vast majority of these cells.
Next up was the remaining core region, which was also the most dangerous area.
It contained Dragon Jail's most powerful prisoners, those who had been imprisoned the longest.
