Without any hesitation, Rein immediately picked up one of them and slowly probed his spiritual power into it.
As the spiritual power delved in, a large amount of knowledge about making various mechanical devices surged into Rein's mind, including things like flame throwers and synchronous gyroscopes.
Rein could feel that this knowledge ranged from easy to difficult, from shallow to deep, providing a fairly systematic understanding of Goblin Engineering.
Any wizard who acquired such a complete and systematic knowledge of Goblin Engineering, by spending some time and effort, could greatly benefit from it.
"Goblin Engineering? This is indeed..."
Rein looked surprisingly at the memory crystal in front of him.
He did not expect that this was what was recorded in the crystal.
After a brief thought, Rein decided to note it down first, as this precious information would be greatly beneficial both to him and his school, the Bixiu Mechanization School.
