"Xiao Mo, I'm so tired, let me sleep."

"Your Highness, I was looking at the map at the stone castle just now, and I accidentally discovered that there is a secret room behind that wall."

"What?"

Liu Yi got up suddenly, but she was really tired tonight, so she held her waist with her hands and got out of bed with difficulty.

Chen Fang looked at her uncomfortable appearance, did he do it, and made a world Valkyrie like this.

Chen Fang helped Liu Yi, and when the two got there, Chen Fang opened the secret room in the previous way, and Liu Yi saw that there was indeed a secret room behind the map, and he had already stepped into it.

Naturally, Liu Yi also saw the piece of wood, she easily took it out, and the wood was not heavy. At this time, there is still a drop of solidified wax oil on the wood, and you can naturally see the corner of the text appearing on the wood.

"Xiao Mo, quick, use wax oil to make all the words on this piece of wood visible."

Chen Fang was originally for this, he told Liu Yi about this before, but he was not afraid to let her know.

How does she know, she understands chemical formulas, the laws of physics, and Chinese pinyin?

There are many things that have not been systematically studied by later generations, even if they are put in front of you, and you can't understand them at all. At this time, Hanyu Pinyin is like this, for Liu Yi, it is a lot of passwords that cannot be deciphered at all, and Chen Fang does not need to hide it at all.

The wax of a few butter candles was plastered all over the wood, and at this time the text on the wood that could not be viewed was displayed, no, it was pinyin.

Liu Yi looked bad and looked at Xiao Mo.

"What our ancestors left behind, we juniors can't decipher at all."

Liu Yi sighed, it seemed that she was still unwilling, and watched it a few more times, but unfortunately if she could understand it, she would also be a traverser. Hanyu Pinyin is something that the ancients couldn't understand at all.

Chen Fang looked at it openly at this time, without concealing it at all, and told Liu Yi that the benefits of this matter were so obvious, how he wanted to look at it, he didn't have to be sneaky. Anyway, Liu Yi didn't know that she could understand it.

However, there is no punctuation, and pinyin is also a little difficult to read.

However, when the whole sentence is connected, the meaning of it is known, it is nothing more than a waste of energy.

"Hi, hello, my name is Liu Naihe."

Chen Fang read the first sentence, and said in his heart, no wonder you crossed into Liu Xiu, your name, how did your father brutally break the word Xiu and give you the name.

"I'm a geography professor and a nautical enthusiast with a passion for military affairs. It's been 30 years since I came to this era, and I'm not fit in with it. ”

"I don't know how I became Liu Xiu and the leader of a group of peasant armies. Where can I fight, so I was beaten by other peasant armies and Han armies and had to flee outside Shanhaiguan. ”

...

Chen Fang looked at it, and sighed helplessly in his heart, this senior was so long-winded, and described his life in detail in Chinese pinyin, how he defeated the battle, how he was bullied by the natives of the Northeast, and he was almost exterminated by the natives.

And then he boasted about his son, how the son was amazing, how he defeated the natives, how they gained a foothold in the northeast.

Then it is how his son expands his territory, and then how he is obedient and how he honors him.

This family is often narrated, and Chen Fang is a little helpless.

"In the twilight of life, I think I have to leave something for the later travelers, so I sorted out what I learned and left it to the younger generations, and several of those things left behind were written in Hanyu Pinyin, in case the later travelers were crooked nuts, they couldn't be cheaper."

"When you see this, I know that all my efforts have not been in vain."

After reading it, Chen Fang breathed a long sigh of relief, in fact, the things on this piece of wood do not have much substance, and most of the content is known to the Liu royal family, and it is recorded in the family records of the Liu royal family. At this time, the wood was just written in another pinyin that they could not read.

After reading this, Chen Fang also completely understood the helplessness of the Liu royal family, the treasure left by the ancestors, but they couldn't open it, there was no key, so they could only guard it empty.

No wonder there are so many foreign books in this castle, you are wrong, you are wrong from the beginning, you want to unravel the content of these books written in Hanyu Pinyin, but you study from Latin and foreign languages, how can this be possible to unravel the content of these books, this mistake is wrong for hundreds of years, then let them continue to be wrong!

Chen Fang looked at Liu Yi, how to get in touch with those pinyin notes at this time is the key, although he can understand this thing, he must also see it.

Liu Yi sighed there, looked at Xiao Mo, and then sat weakly on the wood.

"Your Highness, I don't understand it either."

Chen Fang also sighed and sat on the piece of wood next to Liu Yi.

"Xiao Mo, do you know where those flint guns and ironclad ships of our big man came from?"

Chen Fang shook his head.

"It's from the notes of the ancestors, and there are a lot of illustrations in those notes, and we barely made these, but the words in the notes are like this, and we can't decipher them at all."

"Xiao Mo, if one day we can decipher these words, the strength of our Han will be even stronger."

Chen Fang looked at Liu Yi, and could only be glad that the Northern Han royal family could not untie it, if it was unraveled, he was afraid that the strength of the Northern Han Dynasty at this time, the Tang Dynasty and Western Qin would not be able to parry it at all.

At this time, it can't be solved, the ironclad ships and artillery muskets are enough for Datang and Xiqin to have a headache.

"Then can Xiao Mo try to untie it for His Highness?"

"Except for the Liu royal family, those things are not allowed to be viewed by outsiders."

Chen Fang sighed, thinking helplessly in his heart, this has come full circle, and the final problem is that he can't see those notes.

Going around and around, this is coming back again, and I can't see what my predecessors left behind, even if I can understand it.

Now I have to find a way to see those pinyin notes, but how to see this thing in the royal secret vault of the Northern Han Dynasty.

Even if Liu Yi is the princess of Jingnan in the Northern Han Dynasty, she is only a princess. You can't break the rules of the ancestors and take people who are not from the Liu royal family to the secret vault.

How do you see those notes, peek at them, and sneak into the secret vault to see, it seems that you can't do it at all, the palace vault of the Northern Han Dynasty must be tightly guarded and terrifying, and in that kind of place, there must be institutional personnel like the Tang Dynasty Guardian Prison or the Five Mansions and Four Courtyards of the Western Qin Dynasty.

It's almost impossible to peek, but you can't get in if you're upright, so it's stuck here.

There is no treasure mountain, but there is no path to it, Chen Fang is a little helpless.

At this time, he and Liu Yi were sitting back to back on this piece of wood, Liu Yi was worried because he couldn't unravel the text of those notes, and Chen Fang was worried because he couldn't see those notes.
