"Yue'er, are you sure there's another secret compartment here?"

In Liu Xie's bedroom, Ma Chao looked at the neat bookshelves, and he couldn't see any mystery here. But when Liu Yue heard this, he smiled, and after touching an inconspicuous bulge in the second grid on the upper right, he only heard a 'click', and the book grid with ordinary bamboo slips immediately popped open a gap.

"Sure enough, there is something inside, thanks to Yue'er's delicate mind at the beginning." After Ma Chao praised Liu Yue, he stretched out his hand and began to pull out the secret grid, and at the same time secretly prayed in his heart that Liu Xie would not have time to take the contents when he fled.......

"Concubine Guan Liu Xie doesn't care much about the things in here." After Liu Yue heard Ma Chao's praise, his face was even more radiant, and he continued: "Although he kept it very strictly, he didn't stop shouting at the concubine that time, but checked it leisurely. Presumably, what is placed inside should not be anything important. ”

"This time, the Xiongnu invaded Chang'an, less than two hours, if Liu Xie fled in a hurry, he would definitely not be able to take the things inside. If you think it's useful, you can bring it to ........" Liu Yue said this to herself, and found that Ma Chao had not replied, so she looked up at Ma Chao's face. But at this look, she suddenly found that Ma Chao's face could almost be expressed in a brilliant way.

At this time, Ma Chao's face flashed with a complex expression that Liu Yue had never seen before, including shock, joy, wry smile, and nostalgia, and the careful Liu Yue even saw a trace of indescribable sadness in Ma Chao's eyes.

"Husband?" Liu Yue couldn't help but be a little surprised when he saw Ma Chao so demeanor, and touched Ma Chao lightly, intending to wake Ma Chao up from that complex emotion: "What's wrong with you?" ........ Hey? What is this? ”

Liu Yue stretched out his jade hand, took out a square thing, and asked. After Ma Chao took the thing from Liu Yue's hand, he said in an unusually strange tone: "The name of this thing is Kidney Five, because the shell is golden, it is also known as local tyrant gold, which contains mysteries and is all-encompassing. It was made by the barbarians outside the Fangwai, and after it was revealed to the Central Plains, it was highly sought after, and it once had the reputation of 'high-end atmosphere and grade, low-key luxury and connotation'. If it is an ordinary man, if he holds it in his hand, he can confuse thousands of women and seduce them invisibly. It's a must-have for home travel and making friends......."

"Is this really that amazing?" Liu Yue didn't look like Ma Chao was ridiculing herself, so she couldn't help but take the thing in her hand again, look it upside down and turn it upside down, and muttered: "The concubine grew up in the palace since she was a child, and she has seen a lot of luxurious things. And this thing is neither gold nor jade, it should not be eaten, and it cannot be worn........ The value is as high as the husband said, but it is the first time I have seen it. ”

Ma Chao couldn't help but smile bitterly when he heard this, and said silently in his heart: "This Apple Five, but it is a high-tech product 1,800 years later, if you have seen it, it will be strange........."

"The Han Dynasty is rich in land and resources, and there are some things that Yue'er has not seen, and it is reasonable." Ma Chao stretched out his hand and took the Apple Five again, tried the boot button, and saw that the local tyrant gold screen really had no reaction, and couldn't help but verify the guess in his heart: This Apple Five, I'm afraid it crossed over here with Liu Xie. It's just that in three years, the battery has long been out of power, and it can't be turned on. Presumably, Liu Xie also felt that this local tyrant gold would not play any role in 1,800 years, so he threw it into the dark grid as a thought.

But when he looked inside, Ma Chao's expression was replaced by surprise. After seeing him take out a few books, he said in ecstasy: "Liu Xie still has these books?!" ”

When Liu Yue heard this, he couldn't help but step forward to take a look. I saw that the book was made of fine wind-lifting paper, and the compilation was unusually neat and strong. After reading a few chapters in his hand, Liu Yue also spoke: "There is such a person in the world, who can write so horizontally and vertically, with edges and corners, square glyphs, and stiff strokes. Especially between the words, the size is the same, as small as a black ant, it is really a must in the world! ”

"This? ........" Ma Chao was speechless for Liu Yue's statement that he only praised the gravel when he entered Baoshan. But thinking that there was no printing in this era, Ma Chao felt that Liu Yue had reminded him that he should bring live printing to the Three Kingdoms as soon as possible and carry forward the second invention of the four great inventions in advance.

"Yue'er, don't you see the value of the content of these books?" Ma Chao spread the three books on Liu Xie's dragon bed, and continued to say in ecstasy: "With these three books, the Ma family can be at least a hundred years ahead of this era!" ”

These three books are very familiar to Ma Chao! They are "Iron and Steel Smelting Encyclopedia", "Crop Hybridization Handbook" and "Manufacturing Process of Construction Engineering Materials". Among them, the "Crop Hybridization Handbook" is also a professional book of Ma Chaonong Base Station in the previous life. And the other two, if Ma Chao remembers correctly, also bought them back by himself and put them on his desk for his usual study.

In his previous life, Ma Chao has always had a dream in his heart and struggled endlessly. He bought those two books naturally to learn more knowledge and crafts. At that time, he was depressed at the agricultural base station, and heard that the metallurgical industry and the construction industry were more popular and had oil and water, so he wanted to change his career through self-study, so as to earn enough money and have a certain amount of capital, and then hook up with the beautiful accountant of the agricultural base station.

But seeing these three books again at this time, Ma Chao couldn't help but smile bitterly and shook his head: just learn technology, don't understand the sophistication of human feelings, and the way of doing things, no matter what kind of industry he is engaged in, he can only get a pitiful dead salary, and he will never get ahead. Especially when I wanted to turn over and pursue a girl after I had a certain strength. It's even more ridiculous to think about it at this time.......

After flipping through it again, Ma Chao was even more sure that these three books were the three books that were usually placed on his desk. Some of the notes recorded in it seem to have returned to Ma Chao's mind, like a dream of Nan Ke.

And Liu Yue saw Ma Chao's demeanor, and seemed to feel the ups and downs of Ma Chao's mood. However, after a few more painstaking glances, she still shook her head lightly and said suspiciously: "Husband, do you know the words in these three books?" ”

Ma Chao was stunned for a moment, and suddenly thought that these three books were all printed in simplified Chinese. Liu Yue could probably recognize a few of the words, but it was impossible to read them through. In particular, some of the technical terms are unheard of by her. And Liu Xie may have given up reading because he couldn't understand the difficult and boring content, right?

It's unlikely, though. At least, Ma Chao felt that Liu Xie could already forge a sharp but inflexible blade, which should be inseparable from the "Steel Smelting Encyclopedia".

Perhaps, it is also possible that Liu Xie was in the intricate political whirlpool at that time and did not have the time and energy to engage in these things. He may need to wait until he is an adult and really takes charge of the imperial court, and then use these three books to strengthen the Han Dynasty.......

However, in any case, Liu Xie left these three books, which is really the biggest mistake and failure of his life. After Ma Chao got these three books, he could completely leave the other princes of the Han Dynasty far behind, and use the power of advanced technology to arm the entire Ma family. Then, the unification of the Han Dynasty is no longer a difficult task.

But at this time, Liu Yue suddenly said again: "Huh? Husband, in the dark grid, there is also a piece of wind paper? It seems, or a letter to you? ........”

When Ma Chao heard this, after reaching out to take the piece of paper, his face suddenly changed, and he seemed to be able to drip water gloomily! In the end, he sighed and said miserably: "Liu Xie, Liu Xie, I thought that you didn't take these three books away in a hurry. But I never thought that you actually wanted to use such a killing move to drag down the entire Ma family!! .......
