"Yun Shu, it's okay, go in directly, since the national teachers have already spoken in person, what are you still thinking about." Chu Yuchen noticed Song Yunshu's strangeness, stopped, and glanced back at her.

Qing Han also noticed the movements of the two at this time, and his hand that was about to push away the study paused.

"Lord Song, although only the national teacher can enter the study room of the Tianxiang Palace, but with my (yǔn) Xu, you don't have to worry about anything."

"It seems that I am thinking too much, since this is the case, then I have the privilege of witnessing what the study of the National Teacher is like today."

Now that they have already spoken, Song Yunshu doesn't want to twist and pinch anymore.

Qing Han also pushed open the door of the study happily, and the three of them walked in, and Song Yunshu saw the layout of the entire room clearly.

The study room of the Celestial Elephant Palace is indeed very large, it can be said that it is several times that of an ordinary study, but there are not many books in it.

"Lord Song, I see that you seem to be surprised, do you have any questions?" As soon as Qing Han came in, he opened the window, making the room even brighter.

He still didn't stop chatting with the two of them, but he had already started to walk towards the bookshelves, the room was large, and there were many bookshelves, almost every shelf had only a dozen or so books in bits and pieces.

Song Yunshu looked at what book he was looking for, it was probably the book that he had just told them that recorded this fog.

After hearing his question, Song Yunshu also said what he thought in his heart very bluntly. "I always thought you had a lot of books in your study, but I didn't expect so few?"

"Yun Shu, you don't know this, although there are very few books in Qinghan's study, every one of them can make a sensation across the country."

"Almost all the top and highest ranking ancient books in the country are also here with him." Chu Yuchen, who was on the side, found a place to sit down as soon as he came in, listened to Song Yunshu's doubts, and took the initiative to answer her.

"I see, Master Guoshi, can I take a look? I don't usually have anything good (ài), but my favorite thing is to read. Song Yunshu was curious about the books on the shelves and wanted to see them, and there was nothing wrong with what she said.

"I guess a lot of the books in your study are not recorded, just by the idea that you have so many tools in your head."

Chu Yuchen smiled and stood up, and took the initiative to pull Song Yunshu to another layer of bookshelves.

Qing Han was looking for books and didn't hear what Song Yunshu had just said.

"It's all outside in the study room of the national teacher, and no one can come in, but I don't know that I was reading here when I was a child, what type do you want to read? I'll help you find it. ”

As soon as he finished speaking, he saw Song Yunshu's shocked eyes, and said helplessly: "What kind of eyes are you?" Don't have anything you'd like to see? ”

Song Yunshu just wanted to nod, she was just curious, but the important thing now was to wait for Qing Han to find the kind of book that had a record fog.

"No, since you can come in at any time, will I have a chance to come in the future? For now, let's wait for the national teacher to find the books first. ”

The two were communicating, and Qing Han over there had already found the books he needed and beckoned to the two. "Lord Wang, Lord Song, come here, I have found the book."

"But you have to be mentally prepared, this book is more peculiar." Qing Han didn't say what was strange, and handed it to Chu Yuchen when he walked up to him.

The more Chu Yuchen looked at it, the more frowning he became, and he didn't dare to look at Qing Han confidently. "Are you sure this is really a book?"

Song Yunshu, who was a head shorter than Chu Yuchen, didn't see the content of the book, and pulled his sleeve even more curiously. "Lord Wang, what exactly is it on? Show me. ”

"Wordless Heavenly Book!" Chu Yuchen said this inexplicably and handed the book to Song Yunshu.

After holding it in his hand, Song Yunshu flipped through a few pages that were all blank, and there was not even a trace of ink, which was too strange, no wonder Chu Yuchen would show that kind of table (qíng).

"Lord Wang, Master Guoshi, what's going on?" She couldn't stop being surprised.

"Lord Song, it seems that you have no fate with this book, it is indeed a legendary wordless heavenly book, only those who approve of it can see the words on it, and I happen to be able to see it."

What Qing Han said was mysterious, but Song Yunshu believed it, and Chu Yuchen on the side did not question it.

He smiled and said, "Qing Han, when did you learn to sell Guanzi?" Now that we can see what's inside, let's say, what's going on with the fog? ”

"That's right, didn't you say that these fogs are fine? What we care about now is whether it will move over the state of Chu. ”

Song Yunshu unconsciously cared about the people of the entire Chu State, and in modern times, it was an era of peace, and everyone lived and worked in peace and contentment.

Unlike this ancient world, where there will be wars at every turn, Song Yunshu really hopes that this kind of natural disaster will not occur again**.

Qing Han didn't answer the words of the two for the first time, but took the book and read it again, only to see him casually flip through a few pages.

Only then did he turn his head out of the window, looking unfathomable.

"Lord Wang, Lord Song, you don't have to worry at all, don't worry, the fog on the water will definitely not reach the border of Chu State."

"It will not erode any grass and leaf of the motherland!"

What Qing Han said was very certain, Song Yunshu couldn't help but believe it, but Chu Yuchen on the side heard the meaning of the words. "Qing Han, why is this happening? How did you find out? There are certainly explanations in the book. ”

"The formation of these fogs does not happen overnight, but over many years, and its toxicity is also related to the geology over there."

"After reaching the water, I gradually came into contact with the border of Chu, and the geology here is different, in fact, the fog has begun to slowly disappear."

"The more you move towards the border of the Chu State, it will only speed up its disappearance, which is why you see different fogs from different angles."

Song Yunshu suddenly realized in an instant, and did not listen to Qing Han continue, but directly grabbed the topic. "Master Kuni, do you mean that after I put it in, it left the air there, so it turned black? Does this mean that the mist in the container is no longer free of any poisonous gas? ”

It turned out that this was the case, all the doubts in Song Yunshu's heart were solved, she also found out the problems of soil quality and water source over there at that time, but she didn't expect that it was this river that saved the entire Chu country.

"Yes, Lord Song is very smart and witty!" Qing Han praised without hesitation, Chu Yuchen, who didn't care at all, had already darkened his face.

The woman who praised him in front of him, only Qing Han dared to do this, if it was someone else, he would have broken his neck a long time ago.

"Yun Shu, since you already know, then this mist will stay, I think the national teacher will definitely be useful."

Chu Yuchen's suggestion Song Yunshu also agreed, and nodded at him, since it was decided to hand over the mist to Qing Han, he could solve it as he wanted.
