"Where's Childe? In the carriage? Did I find something interesting? The little third son began to yell at the carriage, and the people around him were used to his character, so they didn't say anything.

It's just that he has the temper of a child, but the soldiers are curious in their hearts, why Song Yunshu came to the battlefield with this young man.

Only the soldiers who followed Song Yunshu knew that this young man was not just a child, his martial arts were higher than anyone present.

"Little Sanzi, what did you find?" Song Yunshu is not just just curious, but what can interest the little third son is definitely worth seeing.

"Shadow Ten, let's go over and have a look!" Song Yunshu jumped down from the carriage with a heroic appearance.

She didn't squirm like a woman, which made Shadow Ten quite admire.

In a place like the battlefield, he is not here to put on a show, and Song Yunshu can behave so calmly, he is even more impressed.

The reason why Chu Yuchen asked him to come forward to protect Song Yunshu was just in case, now that Lord Song was going to see something unknown, of course he had to accompany him.

However, he is not a person who talks a lot, he directly proved it with his actions, and walked in the direction where the third son left, Song Yunshu shook his head helplessly and followed.

Qian Shen was still busy with the aftermath and didn't notice the movements of a few people, but the soldiers around him found out that it was not dangerous to look at the direction they were over, and they didn't pay attention to it.

After walking for about a quarter of an hour, the soldiers behind him also threw a considerable distance, and Song Yunshu finally realized that something was wrong, and they were walking towards the water's edge at this time.

"Little Sanzi, what did you find?"

The little third son, who was running forward, stopped when he heard this, and looked back at Song Yunshu with an innocent expression.

This is still very rare for Song Yunshu, and he has seen this kind of expression on the face of the little third son.

"Childe, I noticed that the water in this river next to me is very strange in color, some places are green, and some places are blue."

Of course, the third son will not be idle and bored to observe this thing, he also heard what Song Yunshu said in the cave just now.

Song Yunshu and Chu Yuchen left just now, and Qian Shen wanted to go before and after the battlefield, he was bored alone and thought about coming over to take a look, but he didn't expect to really find out that something was wrong.

Hearing him say this, Song Yunshu noticed that the corners of the little third son's clothes were still a little wet, and they were dripping with water, although he used internal force to dry the clothes, he missed a little.

Song Yunshu stared at the little third son seriously: "Did you enter the water just now?" ”

"Childe, don't be angry first, I don't dare to swim far, I just observed at the edge for a while, the water on the top layer is green, and the bottom is blue."

"But I noticed that the darker the color, the more chaotic it became, and in the end the two colors were directly mixed together, but some of them were as incompatible as water and fire, and they were still separated."

The more Song Yunshu listened, the more frowning he became, but Ying Shi on the side didn't understand, he didn't understand at all.

"I seem to know what's going on." Song Yunshu has such a high IQ, and after thinking about it for a while, she finally understood what the truth was, but she still needed to confirm it.

The little third son continued to walk forward, bringing the two to the side where he found that the water was of different colors.

After arriving at the destination, Song Yunshu found that there was indeed no difference on the surface, but the fog here was very thin, and compared to other places, it could almost be said to be gone.

Song Yunshu stayed here for almost an afternoon, and she finally determined the explanation in her heart, but she didn't dare to go into the water to see what the scene was.

In the end, it was Ying Shi who took over this important task and entered the water to tell Song Yunshu everything he saw.

"Lord Song, that's all I see!"

Listening to his words, Song Yunshu was already shocked in his heart, he didn't expect such a strange scene in such a place.

If it weren't for her inhuman ability to accept, ordinary people would definitely be scared to death when they came.

"Okay, I already know what's going on, let's go back and tell the prince now."

Ying Shi and Xiao Sanzi are still confused, but they won't understand it with their IQ, as long as Song Yunshu can solve it, the others are not a problem.

They have nothing to dwell on!

As soon as Song Yunshu returned to the temporary camp at the entrance of the cave, he saw that Chu Yuchen had also returned, and it was already dark at this time.

"Lord Wang, come on, I found a strange scene!"

Song Yunshu beckoned to Chu Yuchen as soon as he saw him, and the two entered a tent alone.

"Today I went to observe the water, what kind of eyes do you have! Xiao Miko and Kage Ten are following me! As soon as she was halfway through speaking, Chu Yuchen's face was wrong, but fortunately, she reacted quickly and said that she was not in any danger.

After watching Chu Yuchen's expression calm down, Song Yunshu continued: "The water here is not ordinary, it is very likely that part of it is mountain springs, and some of it is ordinary river water, do you remember the sea I told you?" It's amazing that there is seawater in there! ”

"Don't listen to me that it's all water, but they don't have the same density, and there are three of them in this river, so they have different colors, and they often form that kind of whirlpool!"

“...”

Song Yunshu tried his best to use words that Chu Yuchen could understand, but in the end he still didn't understand, but he asked the key point of the question.

"Does it have anything to do with the fog?"

"Ahem, don't you slap your face like this, okay? I just knew that the pond did have access to the outside world, and that it was not a threat, and that the water was not contaminated with the toxins of the fog..."

Song Yunshu's words became quieter and quieter, what she found was really useless, what really worried people was the fog on the water.

"It's okay that you'll be able to find this, and don't be discouraged." Song Yunshu's cute appearance made Chu Yuchen's desire to protect it all revealed, he stretched out his hand and rubbed her head, and said dotingly.

Seeing that Chu Yuchen didn't blame herself, Song Yunshu was embarrassed in her heart, although her knowledge was very profound, she couldn't solve practical problems, it was really useless.

"Lord Wang, it suddenly occurred to me that a person might know what was going on, he was different from us after all!"

Song Yunshu suddenly thought that someone could solve this trouble, maybe he would study what the toxin in the mist was, and then deduce whether it would float to the realm of Chu according to the weather.

Chu Yuchen frowned slightly: "Do you mean Qing Han?" ”

"That's right! It's the National Teacher, he probably knows something, and the telescope I gave him can see the center of the fog, don't we all see what's in the fog at the border water source of the two countries? ”

After listening to Song Yunshu's words, Chu Yuchen nodded thoughtfully, it seemed to be the truth.
