In the middle of the night, Zhao Yu and Cui Lizhu were still busy at their desks. The two were both excited and nervous, wondering what they could find out from the box left by Tao Xiang.

Cui Lizhu had already carefully cut the outer skin of the suitcase with a knife, and was looking at the inside of the box, trying to find any hidden clues inside.

Zhao Yu was checking the contents of the box one by one, as well as looking through the ancient books and Tao Xiang's notes.

"Boss......" Cui Lizhu asked curiously while using the magnifying glass function of her mobile phone to check the surface of the suitcase, "You say, will my father's plan have anything to do with gold? I have heard him mention this word many times!"

"Really?" Zhao Yu looked at the book seriously without raising his head, "In my opinion, it seems to be normal for a thief king to often mention gold, right?"

"Hey?" Cui Lizhu began to use her imagination again, "Boss, boss, you say, could my father have discovered some shocking secret......?" For example, the Golden City is not a blind name, there is really gold buried in the city?"

"No, it seems to be ......" Zhao Yu put down an ancient book and picked up another notebook, "I heard Miao Ying say that the real origin of the Golden City is because of the golden chrysanthemums outside the city!"

"No," Cui Lizhu hurriedly said, "When I was in school, I heard that it was the city that the Yellow Turban Army built there after it retreated north! You say, the Yellow Turban Army made such a big fuss at the beginning, didn't they leave behind some important treasures? My father got the clue to this batch of treasures?"

"Xiao Cui......" Zhao Yu pursed his lips, "Although I am the discoverer of the Golden Buddha treasure, I can tell you responsibly, where in the world are there so many treasures?" Besides, the Yellow Turban Army is a matter of the Eastern Han Dynasty, the Three Kingdoms, this has to be ...... Hmm......" Zhao Yu couldn't figure it out, so he simply said, "It's been many years, right?

"It's only 1800 years!" Cui Lizhu said, "I know that the history of the Golden City is no longer than that of the Ming Dynasty, but ...... What if there was an ancient city 1800 years ago, but then it disappeared? Maybe my dad got some inspiration......

"Wait......" Before Cui Lizhu finished speaking, Zhao Yu suddenly interrupted him, and then pointed to a black notebook in his hand and said, "This ...... What is this!?"

"Huh?"

Cui Lizhu hurriedly put down her work and came to watch. But seeing that Zhao Yu was holding a notebook that looked very ordinary, but after just one glance, Cui Lizhu couldn't help but be stunned.

"Boss, I seem to have some impressions ......of this book," Cui Lizhu recalled, "When I was in Golden City, I once saw it on my father's desk, and it seemed to be ...... It seems to be this notebook.,He still had a ruler and drew a picture on the notebook at the time......"

"Really, these ......" Zhao Yu opened the notebook, but saw that the first dozen or so pages of the notebook were not handwritten words, but copies. Zhao Yu leaned over and took a closer look, and then he saw the clue, "Oh...... These copies are glued to the notebook! This is ...... What the hell?"

"It seems to be ......," Cui Lizhu carefully examined and guessed, "It seems to be a memoir written by someone, or a letter or something, right? This text has been written for many years, and besides, this paper ...... It seems like a long time ago...... Is it rice paper for painting?"

"It's not like ......" Zhao Yu stroked it and found that the paper was very soft and very thin. Originally, he wanted to use the invisible identification device to identify it, but he was quickly attracted by the words on the paper.

The characters are all in traditional Chinese, and there are annotations in red pen and some symbols under some of the characters, and it is obvious that those annotations should have been painted by Tao Xiang.

"I'm clicking!" Cui Lizhu's eyes were sharp, and she pointed to a certain text and said, "See? Gold...... Look here......" she pointed to another, "it's still gold!"

Zhao Yu also noticed the word "gold", he turned a few pages back, and found that the appearance rate of the word "gold" was very high, almost every page.

"Oh my God, is it really gold?" Cui Lizhu said in surprise and excitement, "My dad is ...... What the hell are you looking for......"

"Look here......" Zhao Yu recognized a few more words, "These two words are written as treasures"!

"Golden treasure!" Cui Lizhu excitedly grabbed Zhao Yu's shoulder and said, "Boss, are we going to have a big time this time......?" Always looking for a golden treasure!?"

Although the eight characters have not been skimmed, Zhao Yu also felt that it was not trivial, and immediately turned it back, but saw that there was no old paper pasted behind, but it was replaced by Tao Xiang's notes.

Although Tao Xiang's writing has no pen style, it is unusually beautiful, very clean, and easy to understand at a glance. On the last few pages, there are some drawings, maps, etc., which just confirm Tao Xiang's statement that he used a ruler......

"...... here" Zhao Yu flipped the notebook back to the place where the paster ended, and finally found a name from the end, "Liu Dianchen!?"

"Liu Dianchen ......," Cui Lizhu said, pointing to a line of small characters behind her name, "These words are the torture codex...... Torture I know, what is a codex?"

"Do you ask me?" Zhao Yu snapped his fingers, "Why are you stunned?

"Yes, yes......" Cui Lizhu hurriedly turned on her mobile phone to surf the Internet, and within ten seconds she had already checked the answer, she said in surprise, "I click, this Liu Dianchen, it turned out to be a big traitor!"

"Ah, traitor?" Zhao Yu wondered, "Why did a traitor appear again?"

"Whew...... It is written here!" Cui Lizhu pointed to her mobile phone and read, "During the Anti-Japanese War, this person served as the director of the Construction Department of the puppet Manchurian government, as well as the chairman of the Democratic Union, and several chambers of commerce...... After Japan surrendered, he was arrested by the military commanders and secretly executed......

"Huh, strange......" Cui Lizhu also frowned, "I don't know, this name on the codex is this big traitor, a person with the same name and surname, but there are!"

"It's not ......" Zhao Yu carefully observed Tao Xiang's annotation and said, "Look, there are words of torture on it...... How do I look at it, it should be the same person! The interrogation record of the big traitor? Hmm...... Xiao Cui, what is a codex?"

"The Codex is the meaning of a handwritten letter," Cui Lizhu replied, "but the torture codex doesn't understand what it means......! Is it a letter written by a criminal when he confesses the facts of the crime?"

"Big traitor...... Golden treasures?, the puppet Manchurian government?" Zhao Yu pondered, "The puppet Manchurian government refers to the northeast of our country, and the Golden City is among them, is it ......?"

"Tut-tut......" Cui Lizhu answered excitedly, "Is it ...... Is this the last thing my dad wanted to tell me......? Hmmm......"

"This batch of treasures ......" Zhao Yu also guessed with great excitement, "Could it be that it has something to do with Japanese devils!?"

"Come on, come on...... Cui Lizhu pointed to the notebook and said, "Although it's simplified, we should be able to understand it! Not to mention, there is also my dad's annotation......
