"Let's go back first, I almost have the answer in my heart, just wait for a while to verify."

Song Yunshu returned to his original position and called Xiao Sanzi and Xiao Bao back.

"You stay here first, and we'll go back." Song Yunshu instructed the third son.

Xiao Sanzi replied "yes" and continued to accompany Xiaobao to the side to play.

Song Yunshu and Chu Yuchen walked up against the river, so they should be able to find the source of the water, Song Yunshu was in front, and their steps were very brisk.

Chu Yuchen was two or three steps away from her, and Song Yunshu was like a little girl who hadn't grown up in his eyes at this time.

Song Yunshu walked while collecting an unknown small flower by the river. It didn't take long to pick a bunch of purple flowers, which bloomed densely on the stems, and although they didn't look gorgeous, they had a kind of back-to-basics beauty.

"Look, is it pretty?" Song Yunshu turned around and asked Chu Yuchen as he walked backwards.

Chu Yuchen was worried that she was afraid that she would fall if she didn't look at the road, so she hurriedly took a few steps forward and grabbed Song Yunshu's hand.

Then he said, "It's beautiful, but have you ever heard a word?" ”

Song Yunshu thought for a moment and shook his head, "What's the matter?" ”

Chu Yuchen deliberately cleared his throat and said, "People are more delicate than flowers." ”

Song Yunshu's faces on both sides immediately turned red, and he didn't care if he looked good, so he directly stuffed the bouquet of flowers into Chu Yuchen's hand and walked forward quickly.

Chu Yuchen smiled extremely happily.

After playing around for a while, Song Yunshu knew that he had something to do after all, so he took the children's thoughts and stepped up his pace. It didn't take long to go, and his forehead was dripping with sweat.

Chu Yuchen was a little distressed, and hurriedly took out a handkerchief from his sleeve to wipe her sweat.

"Hey, how far is the source of this water?" Song Yunshu was a little anxious, as if he was asking Chu Yuchen, and he seemed to be asking himself.

"Actually, you don't have to be anxious, and you don't have to work so hard." Chu Yuchen said, pulling the corners of his lips and smiling.

"Huh?" Song Yunshu didn't understand.

was thinking about it, but found that her body was light, and she fell into Chu Yuchen's arms.

"I'll take you with me, so I can be faster." Chu Yuchen said and rose from the ground.

Song Yunshu's face was red to the root of his ears, and he was about to break free.

Chu Yuchen said: "Be careful, if you have to break free, the two of us will fall from the sky to the ground with a 'snap'." Of course, Chu Yuchen deliberately scared Song Yunshu.

With his light skills, this is just a trivial matter, and there will be no mistakes.

Song Yunshu heard this, but he really didn't dare to move anymore, but carefully curled up in Chu Yuchen's arms.

After flying for about half an hour, the water became more and more turbulent and louder.

"It's almost there." Song Yunshu speculated.

Sure enough, it didn't take long for the two to reach a valley. It is an inaccessible place, standing on its own as if forgotten by the world.

"This is it, let's go down first, and then look carefully." Song Yunshu said.

Chu Yuchen fell to the ground as he said, and the two held hands and walked through the valley.

"Found it!" Bypassing a huge rock, Song Yunshu finally saw a waterhole.

She originally thought that the water was so turbid because of soil erosion, but now she found that the source of the water was already turbid.

Song Yunshu immediately understood.

"This is the source?" Chu Yuchen asked.

Song Yunshu nodded: "Sit down and rest for a while, I've been flying for so long just now, I'm tired." ”

Chu Yuchen walked over as he said, found a clean stone, and pulled Song Yunshu to sit next to him.

Song Yunshu threw a small pebble into the water, and the pebble quickly fell silent, and he didn't even make a sound. It seems that this pool is very, deep.

"What's going on? The water is so muddy? Chu Yuchen frowned lightly and asked.

Song Yunshu stopped selling Guan Zi in his heart, so he said: "The reason why the water here is so turbid is because there is a heavy iron component in it. ”

After saying a word, Chu Yuchen was even more puzzled than Fang Cai.

"Iron?" Chu Yuchen asked again, "You mean, the kind of iron pot that the common people usually use, or the weapons used in the army or something?" ”

Song Yunshu nodded, "Yes, it's the one we found." ”

Chu Yuchen knew that Song Yunshu knew what he knew, so he didn't ask anymore.

Chu Yuchen had already experienced Song Yunshu's keen observation many times before, so he was not much surprised at this time, and the admiration in his heart was beyond words.

Song Yunshu was looking at the water source and was distracted, but Chu Yuchen gently held his hand, and Song Yunshu didn't break free, so he let him.

Then he said, "The water here contains such a heavy amount of iron, of course, it will not grow good crops." It's no wonder that anyone who uses this water source to grow the land doesn't have a good harvest. ”

Chu Yuchen nodded: "The problem has been found, let's go back first." ”

Song Yunshu agreed, and the two walked back together. This stretch of river is flanked by low shrubs and vines, and is rarely walked by.

This is nothing for Chu Yuchen, but it is very difficult for Song Yunshu to walk.

"Oops." Chu Yuchen heard this, and hurriedly stopped and looked at Song Yunshu beside him.

"What's wrong?" Chu Yuchen asked.

Song Yunshu said: "It's nothing, I stepped on the pebble and stumbled." ”

"Otherwise, I'll take you with me." Chu Yuchen proposed.

Song Yunshu waved her hand again and again, in fact, just now, she accidentally stepped on the water and wet her shoes and socks.

Chu Yuchen didn't know why, he was a little worried about Xiaobao in his heart, although the third son was strong in martial arts, but after all, the two of them had been away for so long.

It's the nature of father and son.

Song Yunshu saw that Chu Yuchen was stunned for a moment, as if he understood his thoughts, and the two of them thought of going together at this time.

"That'...... All right. Song Yunshu lowered his head, "It's just that you're tired." When she went up against the current, if she was defenseless, she was thinking about Xiaobao at this time.

The shy and timid look all fell in Chu Yuchen's eyes.

Chu Yuchen nodded, and did not delay at the moment. picked up Song Yunshu horizontally, and then flew up as lightly as when he came.

Song Yunshu gently closed his eyes in Chu Yuchen's arms. The wind picked up her hair and gently brushed Chu Yuchen's ears, itching crisply.

The scenery in front of you flew by.

When Song Yunshu opened his eyes, he found that they were almost there.

"Let me down, there's still a section to come." Song Yunshu whispered that she was shy after all.

Chu Yuchen didn't answer, and hugged her until she was about to reach her destination, before she fell.

Before he could stand firmly, Song Yunshu gently broke free from Chu Yuchen's embrace.

The two walked forward for a while, and saw Xiao Sanzi taking Xiaobao to play in the sand by the river.

"Xiaobao, are you all right?" Song Yunshu asked.

"It's all good." The little third son replied simply.

Xiaobao had already run over and glued Chu Yuchen. Chu Yuchen picked him up: "Let's go, let's go back to the City Lord's Mansion." ”

A group of four people went towards the City Lord's Mansion together. Chu Yuchen hugged Xiaobao and walked in front with Song Yunshu, chatting as they walked.

The junior son was a few steps behind them.
