Yan Song would never know until his death how Fu Jiujiu knew about the cipher book he had hidden, and of course, he wouldn't know if it was Fu Jiujiu who knew.

This evening, Fu Jiujiu felt a sudden urge to set off fireworks.

Zhou and Mengyan were out with several children, also giggling happily. However, the two couldn't help but chat curiously amongst themselves.

"Lao Si's family, you said our family doesn't have any big happy events today, why are fireworks being set off?"

Mengyan shook her head smiling, "Sister-in-law, who cares? Our family isn't short of money anyway, and besides, Little Sister is happy, aren't we happy too?"

"That's true, these fireworks are beautiful. They can probably be seen for miles around."

The two people talked back and forth, and the elderly Fu couple didn't blame Fu Jiujiu for her sudden whim.

If her bestie wants to do something, she has to let her. If her bestie has any demands, she has to fulfill them.

Soon, Tang Xian arrived.

Zhou smiled and said, “I told you so, fourth brother’s family. Even from this far away, you can see it.”

Mengyan smiled.

Zhou Shi didn't expect that she had still said it, Tang Xian just came because he saw the fireworks.

The two of them played for a while longer, until the fireworks were finished before they rested.

"You looking for me?" Tang Xian's tone was affirmative. "Why didn't you have the guards notify me, and even set off fireworks? Such a waste."

Fu Jiujiu smiled brightly, "Of course it's a good thing."

But she was even happier that Tang Xian actually knew it was her who called him over.

The two of them understood each other perfectly.

"What good news?" Tang Xian was not in a hurry.

Fu Jiujiu arrogantly took a book from the bookshelf in the room and said, "Here you go."

"This isn't…" Tang Xian would never be naive enough to think that Fu Jiujiu went to all this trouble to call him over just to show him a book.

"The characters on this tree, how... are they from where?"

"It is simplified Chinese."

Tang Xian said he hadn't heard of them, but he knew some. He just thought that some looked like they were written by children who had just learned how to write, cutting corners and saving money.

"So, this is the place where He Tianlin and you came?"

Tang Xian is indeed clever.

Fu Jiu Jiu nodded, "That's right, this is also a cipher book."

Tang Xian flipped through a few more pages, recalling the numbers from the intercepted report. Following the method Fu Jiujiao had taught him before, he searched and surprisingly, they turned out to be personal characters.

Checking again, it was just a few numbers. One, two, three - he recognized those. He guessed that Yan Song was reporting the number of soldiers to the enemy country.

He took a bold guess, it should be the number of soldiers from the Li Dynasty at the border.

"Chirp, chirp, you can't take this out."

Tang Xian came back to her senses from shock, looking at the little ball of fluff very seriously, "You know, if you do this, your secret will be exposed."

Fujujiao, of course, had thought about this, and she also knew what Tang Xian was worried about.

She couldn't possibly explain herself to everyone, and she would easily be labeled a demon woman. Even the supreme imperial power, that lofty emperor, might not tolerate her existence.

The progress of a backward civilization to an advanced one takes a long time. This is also true for the things that Fujujiju has come up with, which are only slightly ahead of this era. They look novel but not out of place.

Fu Jiu chuckled, "Tang Qijiu gege, you're silly. Just write it in modern characters."

Tang Xian patted her forehead. "Oh, how could I have forgotten that?"

Fu Jiujiu looked at the little boy, her heart filled with emotion.

He gave up a victory that was within his grasp, but chose to protect his secret.

"Thank you, Tang Qi gege," Fu Jiujiu said sincerely.

At that time, I really hesitated for a long time before telling him my secret. If I had known better, I should have told him sooner.

Tang Xian patted her head, "Silly girl, why are you thanking me? You're the one who helped me a big favor. With this, just see how Old Strict will dare to run there again."

Fu Jiujiu was truly relieved and happy for the Qin siblings. After so many years, their wrongful case could finally come to an end.

Tang Xian recalled the news she had received today and told Xiao Nai Tuanzi about Tang Yang's affairs.

Fujujiao thought for a moment, "Then let's clean up together."

But I'm worried that Father will, for the sake of Fourth Brother, let Fifth Brother off easy.

"Has the Fourth Prince returned?" Fu Jiu asked.

Tang Xian shook her head. "No, today, Fourth Brother wrote a letter to our father. I guess it was Fifth Brother pleading for mercy."

Fu Jiujiu smiled. "The Fourth Prince is thousands of miles away, yet he cares so much about what's happening in the capital. And it seems he truly has a deep bond with his family."

She thought about what Tang Xiulin had said to Tang Xian the last time they met before he left.

If possible, please spare their lives.

Tang Xian smiled.

"The Consort Li is skilled in using poison. The Fifth Prince must have ensured his own safety before doing this, gambling on the Emperor's familial love to save him from death. He put himself in a desperate situation, hoping the Emperor would spare him."

“Maybe I was right.” Tang Xian smiled. “Before, Old Lu told me that my father asked Fifth Brother to be a shield for us weak princes. My father must have been very uncomfortable inside, too. At the time, he had to make a choice. After all, no matter what, Fifth Brother is still my father’s son.”

Fujujiao thinks Tang Yang is buffed up this time and should be able to come out, but the timing...

"Tang Qi Gege, Yan Xiang also received a secret report. With the Fifth Prince appearing at this time, I'm worried things won't be so simple."

>It was because she received a secret report that her animal friends could see the code book. Of course, they didn't know any of the words, but they crawled across the paper following the characters for quite a while before managing to figure out a few.

This is how Fujujiao found out which book was the cipher book.

Of course, she didn't think someone like He Tianlin would write a book himself. It must have come from his golden finger source, some famous novel.

"What about the contents of the secret report?" asked Tang Xian.

Fu Jiujiao shook her head, "He burned through it after a glance. You know my friends, they're all afraid of fire and won't go near it."

"It's already great, you helped me find this, it's been a huge help."

"However, could you please also change this to our wording?"

Fu Jiujiu let out a chuckle. "This is easy, just..."

Fujujiao found another book from the shelf.

"Just go find someone to write it down according to this."

How could you have this?

"Fu giggled and said, 'I'm a girl who loves to read.'"

Classics, whether you read them or not, who doesn't have a few on their bookshelves?

Fu Jiujiu had stockpiled a lot of books in her space before, planning to take a long vacation after completing her mission and read them one by one. However, she ended up meeting an unfortunate end...

She happened to find two copies of the same book in the space, one in simplified characters and one in traditional characters.

Tang Xian put away the book, "You are truly my lucky star. No one has such good fortune."

Fujujiao dreamed again and thought of the old Taoist's words. Tang Xian's qi had been taken away, could it all have gone to her?
