Chapter 490: Early Preparation

"Can you understand this?" Chen Xi turned to look at Lu Xun sitting beside him and asked, "If you can, help me decrypt this. Fengxiao really has too much idle time, writing a letter to me in code, and with so many layers too."

"Ah, yes, I should be able to unlock it." Lu Xun nodded, took the envelope from Chen Xi, and said that Chen Xi had only skimmed through the letter before realizing that it did not contain any translation information. It was just a matter of turning plain code into cipher code and then encrypting the cipher code, without any reference table at all. Although it was not directly translated, the final output was definitely numerical.
