It's roughly confirmed, a special material was used to achieve this, and skill is not the main factor.
I'll ask later, to see if the Immovable Immortal Dynasty still has this material.
Looking back at the large library, stone shelves, with various categories of classics, mostly jade scrolls, gold foil, and stone tablet gold books, which can be preserved for a long time without changing, paper classics are rare.
On the four stone walls, there are portraits hanging, judging by their attire, they should be the emperors of the Immovable Immortal Dynasty over the generations, Zhuge Baolin's portrait hangs in the last place.
As Yu Ziqing looked over, Zhuge Baolin's portrait began to move by itself.
The person in the portrait cupped his hands in greeting.
"Greetings, fellow cultivator."
Yu Ziqing was somewhat surprised.
"Zhuge Baolin?"
