In the depths of the cave, Fog glanced at the resting clouds, and pulled a few of her clansmen to mutter, she looked at the people who were obviously still hesitating.

"I won't lie to you, my son is the best example, and during this time, everyone began to have stomach aches one after another, although it won't kill anyone, but the pain doesn't taste good, we haven't eaten anything else recently, it must be because of wild vegetables, shouldn't we ask Yun Duo for an explanation, and it is not too much for her to compensate us for a piece of beef."

Seeing that their hearts were moved, the fog became bewildered again.

The next day, Yun Duo waited for the stone gate and walked out, she stood near the stream, and waited for about half an hour, when she saw Gaga, and several of her tribesmen came to the stream one after another, and drank the water, and looked at this scene and walked towards them with a frown.

"That's how you usually drink water?"

The Quack didn't understand why she asked, but nodded anyway.

"Who hasn't eaten in the morning?"

"Me!" Quack watched her speak.

"I didn't eat either!"

"And me!"

Yun Duo looked at the three people who came out led by Gaga: "I have heard the rumors in the tribe that eating wild vegetables will cause stomach aches, I want to prove one thing to everyone, the reason why the clansmen have stomach aches is not because of wild vegetables, so I need your help, and each person has a bowl of ox blood afterwards, you are also willing to help me?" ”

"Yes! We do. Quack's eyes lit up slightly, and he hurriedly spoke.

"Clouds, how can I help you? We also want to know what causes the stomach ache. The rest of the tribesmen also came over and spoke.

Yun Duo looked at them and explained, "Actually, it is the stream that causes everyone's stomach ache. ”

Several people muttered in surprise when they heard her words.

"Impossible, right? We used to drink water like this, why didn't we have a stomachache? ”

Yun Duo organized a language to make her people understand her meaning as much as possible: "That's because you all lie in the cave at this time before, and rarely come out to drink water, haven't you noticed that the stream has been a lot muddy lately?" In fact, there are a lot of creatures in the stream, such as fish, snakes, turtles and the like we can see, but there are also some very small creatures that we can't see, now the weather is getting warmer and warmer, and the rainy season is coming, they are like poisonous insects in the woods have begun to come out to move, and when you drink water, you will naturally have a stomachache when you drink them like this. ”

After hearing her words, several people's faces changed slightly, and they became a little ugly.

"Can't we all drink like this in the future?"

It is difficult for the tribesmen to change the habit of drinking raw water, and there is not enough firewood, knowing that they have believed her words, she shook her head and said: "Naturally not, but this time is a little special, these little creatures used to be active under the water, because of the rainy season, they now swim to the water, this time naturally can no longer drink water like before, but after the rainy season, the water becomes clear." ”

The people of Gaga, who listened to her words, finally breathed a sigh of relief.

"Doesn't that mean we won't be able to drink water all this time?"

"No, it's okay to boil the water after filtering, I've already thought of a way to filter it."

Before she could speak, she squatted down: "My stomach hurts, my stomach hurts." ”

Yun Duo saw that it was one of the three people who shouted that his stomach hurt, and looked at the Gaga: "Now you should believe what I said, right?" ”

Several of them nodded at the same time.

"Pick him up, let's go back to the cave."

Before Yun Duo led them back to the cave, he saw the fog leading the nine clansmen over, and Yun Duo looked at them and raised his eyebrows slightly.

"The clouds are there!."

The fog shouted, and the nine men sped up and walked towards them menacingly.
