Huang YiYi made a password game using four letters, cleverly used password games and An ZaiTian to speculate on the "light secret" encryption technology. At the same time, she hinted that An ZaiTian's own thoughts were in this password game. An ZaiTian decrypted the confidential letter and four big characters came into view - I love you very much. An ZaiTian has always been indifferent to Xu YuanZhang's persuasion of his personal problems. He told Xu YuanZhang: First of all, he loves his wife Yu Yu. Second, everything is now necessary to make way for light. An ZaiTian found Huang YiYi euphemistically rejected her feelings and Huang YiYi could not understand the behavior of Ann. Huang Yiyi's dream gave her the inspiration to make a screen-type cipher, and soon he took action to stop wondering about the geometric model. Instead, he seized the time to make a screen-like cipher machine. Although Huang YiYi's conjecture was denied by Chen Erhu, An ZaiTian still saw another way out, and decided to invest all the labor to verify Huang YiYi's conjecture. All calculation staff including Huang YiYi and An ZaiTian devoted all their energies to this conjecture within a month. However, the result was guessing mistakes. Huang YiYi rushed out of the calculation room with tears. An abacus battle, the end is scattered.
