尔等可曾听闻歼10改？

Have you ever heard of the J-10 modification?

Lu Chen traveled through the parallel world, bought a modification factory, and unlocked the "Super Book Black Technology System".
Just read any relevant information, including books, drawings, documents, etc., to unlock relevant ultra-black technological knowledge!
On this day, Party A brought over a retired J-10 fighter with only its shell left, and asked Lu Chen to clean it up and renovate it. It would be displayed at the air show in a month, and it had to be high-end and classy. As soon as he saw the exhibition Fighters should give people a sense of unconsciousness!
Lu Chen looked at Party A's request documents and drawings and couldn't sleep! You still want to know Mingli even if you are an empty shell?
【Ding! Congratulations to the host for reaching 100% progress in reading the drawings! Obtain "a complete set of black technology knowledge related to the construction of the Baidi Fighter"]
Lu Chen: "Why don't you know Mingli? I'm here to give Party A a little shock!"
A month later, the Baidi fighter jet appeared at the air show! Shocked the whole audience!
Dean of the Longke Fighter Research Institute and the general person in charge of the "Baidi Fighter Plan": "The Baidi Fighter appeared at the air show? Who leaked our Nantianmen Plan!"
