[Hearing your inquiry, Jade took the Train Core and gave it a try, using her Equivalent Exchange innate talent again to exchange for a Train Core.]
[In the end, Jade stored the Train Core into her item inventory and shook her head, "I still can't exchange for them. The Train Survival World should have highly regulated the Train Core, and it's impossible for it not to know what my innate talent is."]
["Not only me, but other Train Conductors should have similar talents to mine, even if they're of lower rank. Because of that, the Train Survival World's Will must have imposed restrictions on those items that are unique and crucial to the Train Survival World."]
["Perhaps, the only reason I can exchange for those resources from station worlds was due to them not having problems when they're duplicated. I haven't encountered that many items with restrictions on having multiple copies like the Train Core and Train Coins, so I can't figure it out with a limited sample size."]
