The Old Death God rambled on for quite a while.
He also talked about the nature and usage of these high-energy high-dimensional materials.
Regrettably, although Matthew could understand some of what was said, it seemed as if a thick mosaic had blurred the information, making it impossible to visualize and comprehend in his mind.
All he could do was forcibly memorize it deep in his mind.
Despite talking so much,
The materials that the Old Death God took weren't much, only about a third of what Matthew encountered in the world of the Rootless River with that crow.
Matthew wanted to give more, but the Old Death God waved his hand, refusing.
"For someone who is already dead, all this is already enough."
The Old Death God's words left Matthew somewhat perplexed.
However, the next sentence made Matthew's spirits surge:
"Now go to the tomb chamber, open that sarcophagus; what's inside the coffin is a little trinket that I have brought for the trade."
