My friend has some top-secret government intel. He left a message, but the government censored him! They didn't want the information to be leaked, but can you find out what he was trying to say?

nc p1.tjctf.org 8003

Ok, no other clue, so let's try the command.

╰─ nc p1.tjctf.org 8003
To prove you are worthy of this information, what is 10 + 5?
15

tjctf{[CENSORED]}            

Hum, we have the flag but with the censorship. Let's try to pipe the output of the command:

╰─ nc p1.tjctf.org 8003 | more
To prove you are worthy of this information, what is 4 + 6?

tjctf{TH3_1llum1n4ti_I5_R3aL}

Magic! The flag appears and stay without the censorship!
