Controllable nuclear fusion?!
This does sound interesting.
Lu Zhou was immediately interested once he heard Professor Klitzing mentioned this matter.
"Can I visit inside?"
Professor Klitzing smiled and said, "If you are interested, then sure."
Lu Zhou followed Professor Klitzing into this building.
Lu Zhou thought that this place would be highly confidential, but Professor Klitzing easily went inside with his work card.
Professor Klitzing noticed Lu Zhou's confusion and smiled as he said, "There's no secret here. You can retrieve the papers from the Firestone Library. The access restrictions are mainly to prevent troublemakers from coming in. The security in Berlin has gotten worse recently."
Lu Zhou joked, "I thought it was some highly confidential place."
Professor Klitzing smiled and said, "Don't worry, even I wouldn't be able to access a place like that."
