If there is one substance to represent Chinese culture, it is jade.

Jade has a very special position in the history of Chinese civilization. Among Chinese characters, all Chinese characters including the character "jade" have a beautiful meaning.

The Chinese people's tradition of loving and worshipping jade began thousands of years ago in the Hongshan Cultural Period, the Liangzhu Cultural Period, and the Lingjiatan Cultural Period...... It has been inherited from ancient times, continued to future generations, and is still the same today.

The land of China nurtures a multi-ethnic family, and compatriots from different regions and nationalities may have unique characteristics in customs, lifestyles and even religious beliefs, but in terms of the use of jade, it has shown amazing consistency for thousands of years. Whether Han Chinese, Khitans, Mongols...... All have developed the custom of using jade and good jade.

According to relevant historical materials and archaeological excavations, even the ancients still mastered very exquisite jade carving skills even without metal tools, such as: wire cutting method - that is, the process of cutting with hemp rope and water, and so on......

"Baby, where did you get that?" Wei Huadun stared intently at the carved jade in his hand, and his voice was extremely serious.

Luoluo pointed to an old clay pot that had been discarded in the corner of the house, covered with dust, and replied truthfully: "It's in that jar, I was going to use it to store some water......"

"Captain," Wolf stood on tiptoe and tilted her head, she had been looking at it with Wei Huadun for a while, "what clues did you find?" ”

Wei Huadun dropped his arm and handed the carved jade to Ah Wolf.

"I don't know anything about this...... Ah Wolf said truthfully, but he still took the carved jade and looked at it carefully.

Wei Huadun pointed to a small handmade drill hole on the carved jade and said, "Look at this drill hole, what is the diameter?" ”

"Less than a millimeter." Ah Wolf looked at it carefully again, and confidently continued: "To be exact, it should be between 0.7~0.8 mm." ”

"That's right." Wei Huadun's eyes flashed, and he laughed deeply: "This level of craftsmanship, even in the 21st century, thousands of years later, it is difficult for skilled craftsmen to use more advanced tools to achieve!" ”

"......" fell silently and embarrassed. Since it is difficult for people in the 21st century to do so, this technology should belong to the more distant future......

Ah Wolf comprehended, and said with high morale: "Okay! I know where to look tomorrow. ”

"Hmm." Wei Huadun nodded with satisfaction, turned around and suddenly changed his heart shape in his eyes, dancing with his hands and sa huan to Luoluo, "Bao ~ Bei ~ Ya ~ You really helped a lot!" Let's have a good fancy '?~ma~' celebrate ~~"

Luoluo's face turned pale, but he didn't have time to dodge it......

Ah Wolf suddenly shouted from behind: "Here! ——”

Frightened, Wei Huadun turned around and jumped, "Well~~Na~~?" I'm going to die! ——”

But I saw that Ah Wolf was standing upright, maintaining a military posture, and muttering to himself in the air: "Yes! Elite Nineteen immediately delivered the order. ”

"......" Wei Huadun and Luoluo both understood.

That's right, it was Dr. Duck who sent the communication.

"Whew-" Luoluo quietly breathed a sigh of relief. If she was pasted by Wei Huadun, who was covered in mud and sweat, she was afraid that she would not be able to control and scratch people~

But now, it's a wolf who wants to tickle people......

Wei Huadun put his arms around Ah Wolf's head, and the two sides of their faces were pressed tightly together, and they began to hold an impromptu meeting.

As soon as Dr. Duck's voice came over, he was scolded sharply: "You bastard and deflated calf, you get carried away in front of your girlfriend, you don't know how to pretend to be blind to command, big straw bag!" Under-peeling! ～”

"It's just forcing you to make up for the history of Chinese agricultural civilization, and you really think you've become a 'historical know-it-all', ah? The exquisite skills of the Chinese ancestors in carving jade, how can you question the heavy N generation grandchildren thousands of years later? ”

Wei Huadun was scolded and red-faced, expressing disbelief: "But the 21st century ......"

"Yes, there are some crafts that are difficult to do even in the 21st century, but! In the archaeological excavation of [Lingjiatan Site, Hanshan County, Anhui Province], numbered 'M23 in 2007', 330 antiquities were unearthed, of which more than 200 pieces of jade alone! The largest and heaviest jade carved pig-shaped vessels found in Chinese archaeology are also included. ”

"In addition, several ancient jade figures have been excavated, especially the jade figure numbered '98M29 15', which has a bull's nose and eye type handmade tube drilled in the back, with a diameter of only 0.15 mm! 0.15！！！ Lingjiatan culture is more than 5,600 years away from the 21st century! Nearly 1,500 years before the plane you live in now! ”

"There are also earlier [Liangzhu Culture] and [Hongshan Culture], both of which have many exquisite jade archaeological discoveries. Do you need me to say anything more? You big idiot! ——”

As Dr. Tongya said, this time it was indeed Wei Huadun's misjudgment. But......

"Uh-ahem!" Wei Huadun cleared his throat and replied shamelessly: "Thank you Zhenggu Base for your strong support to our front-line workers, these are what I should do as the best captain of the Elite No. 1 Zhenggu Pioneer and the best captain of this Zhenggu operation, don't reward me anymore~ I will definitely continue to work hard, please tell all mankind in the 32nd century positive time and space, let them be relieved, as long as I am here, there will be absolutely no problem with negative time and space history, salute!" ”

"Wow~" Luoluo tilted his head slightly, folded his hands and fingers together to support his cheeks, and looked at Wei Huadun with autumn water in his eyes.

Ah Wolf bent his arms around his chest, squinting at his two sleepy eyes, his eyes were so slanted that he couldn't slant anymore, glancing at Wei Huadun. She had never seen such a brazen guy......

"You calf, you have to humbly ask for advice if you can't be sure, your father and I are not only proficient in five-dimensional technology, but also very knowledgeable in history, don't you make it! You big idiot, next time you don't know how to pretend to understand, blindly command, delay time, delay big things, look back at me and your mother don't pick up your two layers of skin! ——”

Wei Huadun still didn't blush and his heart didn't beat, and he replied like a matter-of-fact: "Oh, the directors, and the big ball captain of Bi Saturn~ I know that I am very good, so don't praise me like this anymore~"

Luoluo was so shocked that he stretched out his hand to cover his mouth, and the wolf was helpless and his eyes rolled white~

"Still pretending to be in front of your girlfriend, you face-saving bastard, give me a good job of myself, hum!" Dr. Duck slapped the stop communication button hard, the force was too strong, and the mobile phone in his jacket pocket fell out, and the popular science search page was displayed on the screen, with the keywords: "ancient, ancient, jade......"~

When the staff next to him saw it, he immediately had beads of sweat on his forehead, and his mind was full of Dr. Duck's words: "Your father and I are not only proficient in five-dimensional technology, but also very knowledgeable in history, don't you make it!" ～～

"Huh?" Dr. Duck picked up his mobile phone as if he was very confused, muttering to himself: "Whose mobile phone is this, why are you so careless, I have to find the owner and return the thing to its original owner." Hmm~"

The staff member next to him had black lines hanging down the back of his head, and turned his head in embarrassment to continue working, as if he hadn't seen anything.

Dr. Duck patted the shoulder of his glasses, gave a thumbs up, and said very approvingly: "Xiao Tian has worked hard, continue to protect strictly, and the safety of those colleagues on the mission is on your shoulders." Come on! ”

"Yes!" The glasses put down the potato chips in his hand, and the chocolate-flavored ice cream still hung on the corner of his mouth, stood upright, and saluted back: "Please rest assured, Doctor, this is my job, and I will ensure that there is no mistake." ”

"Hmm." Dr. Duck straightened his cap and left. As soon as he came out of the five-dimensional energy program department, he held his phone tightly and went crazy until his facial features were distorted, "Wow - shame on you!" ~~When will the Zhenggu Building invite a qualified 'history expert know-it-all'! ～～～”

～～～

"It's that abominable four-eyed pheasant again! - Wei Huadun could guess with his toes that it must be the glasses that were passing through the invisible communicator on Ah Wolf's body, performing protection work - when making sure that the communication connection was normal, he monitored the conversation between the three of them, and then gave a small report to Dr. Duck.

Ah Wolf felt that Deputy Director Tian had done a good job, and the implementation of the work was both serious and in place, which was something that made the Zhenggu pioneers feel very secure. In fact, Wei Huadun also knows this, he doesn't hate it, but: it's not right for people~ Who makes glasses incompatible with him.

"Elite Nineteen!"

"Here!"

"The content of the meeting just now, except for the boring content that praised the captain, everything else is the highest S~~~ level (wooden table) secret content of this Zhenggu operation, absolutely ~~~ Yes, you can't leak half a word! Otherwise, according to the crime of 'anti-Bi Saturn, betrayal of positive time and space, and leaking the secret of Zhenggu (Muji), you will be sentenced to the punishment of 'donkey kicking the brain'! ~Did you hear clearly? ”

Ah Wolf's two sleepy eyes blinked, tilted his head and said, "How can there be such a punishment??" And Bi Saturn...... There are no such creatures as donkeys. ”

"Dare to talk back? I'll kick without a donkey! ~Did you hear clearly? ”

A wolf turned up his helpless card again and rolled his eyes, "Yes~"

After that, Ah Wolf swapped his dirty sleeping bunk with Wei Huadun's, and then swaggered into the bunk and lay down next to Luoluo to sleep. She didn't like to sleep in the bunk, not because she was afraid of hearing any embarrassing sounds in the middle of the night and couldn't stand it, but because the bunk was so low that there were always bugs that could climb on it.

Before Wei Huadun went crazy, Ah Wolf closed his eyes and preemptively said: "Report to the captain, I have an incurable disease of 'sleeping in a dirty bunk and talking in my sleep', in order not to leak our 'S-level meeting (wood) secret', I have to let the captain you suffer for yourself." Report finished, good night ~ purr purr-"

"I'll rub—" Wei Huadun turned his head to look at the dirty sleeping bun that had been slapped with sweat and mud by himself before, and his whole face was wrinkled into a bun, "Ah! West-"

～～～

There are no words for the time being, and the three of them sleep.

However, stay until the night is quiet, and the moon and stars outside the window are scarce......

Wei Huadun suddenly opened his eyes, quietly got up, and cautiously walked to the big shop......
