The reason why Shi Lei said to differentiate between the upstream and downstream wasn't unreasonable. If it was downstream, it was enough to prove that the water's purpose was to go there and the other upstream was where the water came from.

So, seeing Lin Shan's puzzled look, Shi Lei smiled, and said right away: "Actually, this means that if the water is coming from the upstream, then that place is the source, and the other place is the downstream, which is the direction that it is coming from. Do you know what I mean?"

Lin Shan was still in a daze. It was clear that she still could not understand what Shi Lei meant by saying all this.

Shi Lei had no other choice but to say: "Downstream, there might be the Medicine Garden that we are looking for."

Only then did Lin Shan open her eyes wide, and said: "Why do you say that?"

Shi Lei said: "You took the water from a place, where do you want to take it?"

Lin Shan's body suddenly shook. If someone really did get this water source here at that time, then it was most likely because of the so called Medicine Garden, so that they could charge into the Medicine Garden. But since it was to rush into the Medicine Garden, then the water would definitely rush up the Medicine Garden downstream.

This was what they called irrigation.

Therefore, there was a high chance that this downstream area needed irrigation.

Shi Lei continued: "Even if it's not there, it's more or less there. After many years of change, the downstream area, or should be the surroundings, should be where there's Medicine Garden. As long as there really is a Medicine Garden there. "

Lin Shan could not help but take in a deep breath of cold air, and then said in a heavy voice: "So that's why, if we're going into the water to look for it, all we need to do is go downstream, right?"

Shi Lei immediately nodded. "Yes, we just need to search downstream. We don't need to search across the entire river, it's also impossible to find such a place."

Lin Shan could not help but heave a sigh of relief, because she was not an idiot either. If she were to go and look for the Medicine Garden, if she had to dig the entire river, she would definitely not be able to find it!

The water source was too big. It was like looking for a needle in a haystack. He had to try his luck. How long would he have to stay in the river? As long as it was a person, even if they were professional divers, they would not be able to stay in the river for too long, let alone in the river under the snow mountain. This was completely impossible, because the temperature of the water was definitely very low, and if they were to stay down here for too long, there would definitely be problems, not to mention they were not professional divers.

Lin Shan felt that if she were to stay underwater for a while, she would definitely die from the cold. Therefore, she did not think that she could truly search underwater for three days and three nights at a time.

If they had a target, such as being able to clearly distinguish the way up and down, then it would be easier to find it. This would exclude at least two-thirds of the place, because now that they knew where the downstream was, if they wanted to find it, they would only have to start from the downstream.

"Then what do we do now, go downstream and search?" Lin Shan looked at the river. The current was flowing rapidly, and the current was flowing downstream, she could tell with one glance where it was flowing downstream and where it came from.

It had to be said that even if it was just a normal downstream area, it would still be very dangerous, because if they had to go into the water from here, other than going through the erosion of the cold river, the most important thing would be to be washed away by the rushing river. It wouldn't be a big deal if they accidentally suffered some minor injuries.

Thinking to this point, Lin Shan's face also revealed a slightly pale white expression. It had to be said that at times like this, she could still be considered as someone who treasured lives more, let alone that she currently had a highly toxic body.

Looking at her expression, Shi Lei naturally knew what she was thinking. He smiled: "Don't worry, although this river looks very turbulent, as long as you go to the side, there shouldn't be any problems."

Lin Shan was startled for a moment, and was unable to react for a moment, as she also did not know what exactly this meant. Of course, if she was born in a village, then she would know that the reason why Shi Lei said this was because she was talking about the nearby rivers. It was because there were a lot of nooks and crannies blocking the way, and some stones would occasionally fall from the shore.

In the rural areas, there were many places like rivers and rivers, not to mention a beautiful place like Qingshan Village. In this place, there was even less of a need to talk about it, it was completely a paradise. Shi Lei had also went into the water many times when he was young.

However, Shi Lei would naturally not tell Lin Shan about these, but he slowly walked to the side, he was currently observing, to see where he could go into the water.

Lin Shan followed along and said: "The water in this river should be around five to six meters deep."

Shi Lei immediately shook his head: "It's not that deep. There is indeed a depth of three to four meters, but it would at most be three to four meters.

Lin Shan was startled for a moment, and said: "Why do you say that?"

In fact, from her point of view, this river looked very deep. She said that it was five to six meters deep, but in reality, it was still a conservative statement. If possible, she would like to say something that was a dozen meters deep … She didn't see such a rapid flow of water and began to suspect if this was the Yangtze and Yellow Rivers! Of course, this was also an exaggeration. The main reason was because she rarely saw such a river was because she didn't have much experience with it.

But Shi Lei was different. Upon hearing Lin Shan's question, she immediately smiled and explained to her: "Think about it, what was the purpose of this river in the beginning?"

Lin Shan shook her head, she wanted to say that she did not know, but when she saw Shi Lei's look of contempt, she immediately thought of something, and said anxiously: "I know, this is used for irrigation, but what does it have to do with the water depth?"

To be honest, Shi Lei was actually a little reluctant to admit it. In her opinion, how could the river be so shallow, with such a swift river and in this kind of place, it must be very deep, right? After all, it had been so long, and his aura was so majestic. Plus, under the snow mountain, there would be snow falling, and then it would turn into water again.

That's right, what Lin Shan was thinking right now was that this was under a snowy mountain, so this river was rather deep …

Of course, she could also put her here, but of course, she was also afraid that when the time came, she would have some problems. After all, they were at the bottom of the snow mountain, if they stood there waiting for him, then who knew if there would be any snow avalanche or whatever, and at that time, Lin Shan would really be the only one who would not respond to her call every day, and would be completely unresponsive. Therefore, if it was possible, Lin Shan could naturally follow him and enter the water safely.

"It was originally used for irrigation. Since it was created for irrigation, do you think someone would be so stupid as to dig it deep?" Shi Lei immediately rolled his eyes and laughed: "Needless to say, after going through so many years of changes, the surrounding soil and stuff, will make his original depth even shallow."

Lin Shan was stunned, but when she thought about it carefully, it was not without reason. What was the purpose of this river before her? Since it was an irrigation ditch, then it was definitely unlikely that it would create something like a depth of more than ten meters. Then when the time came, with so much water being irrigated, wouldn't Medicine Garden be drowned? So when Lin Shan thought about it more carefully, she finally understood.

At this time, Lin Shan's heart couldn't help but exclaim. What the hell was this Shi Lei in front of him doing? How did she only know so much about these things?

How could she know, actually, that as long as it was someone who had lived in the countryside before, most of them would know, and she, who spent all her life studying in the city, would naturally not have a good understanding of these things, so it was understandable. Everyone had their own lives and systems for these things, and it was unlikely for them to have access to so many simple agricultural techniques within Lin Shan's circle of living.

"We're going into the water now." Shi Lei walked to a place to the side and said: "Change into a swimsuit, then continue changing into an oxygen tank. We will enter the water from here, the water here is relatively safer.

Lin Shan said with a wry smile. "But I don't know how to dive."

She finally knew why there was a diving suit in these props! That's right, among the items she was holding, besides swimming, there were also diving suits.

So it turns out that they still had to dive into the water. This really made things difficult for her! She couldn't even swim, much less dive!
