This kind of dedication to research was something Tang Yu greatly admired, especially given the many contributions Elder Sun had made.
Elder Sun spoke earnestly, always eager to understand the basics of longsword crafting techniques, yet he never used his authority in Lindong Sanctuary to coerce.
Instead, he made promises.
The science academy was undoubtedly the place in Lindong with the most valuable items, whether it be equipment, gadgets, or anything else. Even if Tang Yu didn't need these things, proposing an exchange with Source Crystals was something Elder Sun would likely be very happy to agree to.
To be honest, Tang Yu was tempted.
There was no harm in taking out the longsword crafting process.
The problem was... the basic longsword was created by the workshop, how would he know the specific techniques?
