Emperor Xiyun immediately asked, "Jingjing, what are your brilliant ideas?" Say it! ”

Quietly: "Our current books are copied by hand, hand-copying is not only time-consuming, troublesome, but also easy to copy mistakes, copying omissions, obviously we will use seals, no one has ever thought about it, according to the principle of seals, a page of words are engraved on a board?" Then, brush the ink and cover the paper, and then all the words on that page are printed on the paper? The other pages are printed in this way and then bound into a book. In this way, it is much simpler, neater and more reliable than hand-copying. ”

As for the ancient movable type printing and engraving printing, Jing Jing has learned it in history textbooks.

Seeing that Emperor Xiyun and Su Chengyu both listened excitedly, their eyes lit up excitedly, and they were quiet and only funny, but they still continued: "This method is actually very simple, even if I don't say it, someone will definitely find out in the future, it's just a matter of time." Father, you can let people do this first, hand-copied books are really too expensive, and the average poor family can't even afford to buy a book, so how can you let your children go to school? In addition, printed books can also be sold to other countries, and they are cheaper than hand-copied, presumably other countries will buy them. ”

After a pause, he quietly concluded: "Small profits but quick turnover, let's make this one first." ”

Emperor Xiyun first praised the quietness, and then handed over the matter of printing the book to Su Chengyu to be responsible, and the treasury paid for it, and the money earned at that time also returned to the treasury.

When Su Chengyu was ordered to do the book printing, Emperor Xiyun first looked at Jingjing, then at Xiao Changyi, and finally, he couldn't help but sigh: "Yi'er, you and Jingjing are really a perfect match." "They're all amazing geniuses! It's really worthy, it can't be matched anymore!

Xiao Changyi squinted at Emperor Xiyun: "You only know now?" ”

Emperor Xiyun was stunned for a moment, and then laughed and said, "How could it be, I already knew, but I haven't told you all this time." ”

Xiao Changyi was satisfied, so he no longer squinted at Emperor Xiyun.

It's funny to be quiet, but it's sweet in my heart.

Leaving from Emperor Xiyun with four children, he thought quietly for a while, and said: "Xianggong, if it is really Linghe who dragged the Pingjun Mansion to treason together, in the future, we are really likely to start a war with Chilin again." ”

When she learned the news that Linghe himself asked to marry into the Chilin Kingdom, she felt that Linghe was uneasy and kind, and now looking at the situation, Linghe is really uneasy and kind, and it is really very possible to fight in the future.

Xiao Changyi didn't say anything, just said lightly: "It's a blessing or a curse, it's a disaster that can't be avoided." ”

Two days later, after severe torture by the Criminal Department, the distant cousin of the Pingjun Wangfu recruited him, saying that the Pingjun King invited him to drink one day, and as soon as he was drunk, the Pingjun King asked him anything, and he said it all, including what kind of raw materials were used to make white paper.

But King Pingjun refused to admit his guilt, and said that it was the distant relative who framed him.

Princess Pingjun also pleaded not guilty.

The sons of King Pingjun also refused to admit it.

They all said that as long as they did not admit their guilt, the words of the distant relatives alone did not condemn them to treason.

And those maids and servants in the Pingjun Palace, because they didn't know about it, no matter how they tortured them, they couldn't ask anything.

But the second daughter-in-law of King Pingjun is a person who is particularly afraid of pain and death, and before she was tortured for a long time, the second daughter-in-law was recruited, saying that she had overheard that King Pingjun and Princess Pingjun planned to commit treason and defect to Chilin Kingdom.
