This notebook contains all the information related to soul research.
Unlike Cha Wenliang's strange and irritable temperament, the records in this notebook are extremely meticulous and rigorous, supplemented with various detailed illustrations and extensive experimental cases at critical points.
Unknowingly, Xue An became somewhat engrossed in it.
At that moment, Cha Wenliang stepped in.
An Yan nodded slightly upon seeing this and then left the room.
Even by then, Xue An was completely unaware of Cha Wenliang's arrival.
Cha Wenliang did not urge but sat quietly by the side waiting.
After a full hour, Xue An finally put down the notebook and sighed lightly.
"How is it?" Cha Wenliang asked.
"Impressive!"
"Of course, this is probably the most genuine and detailed firsthand material on souls in the entire Sky Beyond the Skies," Cha Wenliang said with a bit of pride.
Xue An nodded, "Indeed, but I feel there are improvements to be made in some ideas within!"
