Sure enough, after climbing more than 20 meters, there were more and more stones, and they became bigger and bigger.

In the pit under a large rock, several people found a source of water!

The desert water dragon immediately lay on the edge of the water source and poked his head out to take a few sips.

Ye Yu also immediately took the kettle and was about to fill it.

"Wait!" Ye Zhizhi squatted down and stopped him, "I'll take a look first!" ”

"What's there to see about this?" Ye Yu was puzzled, "Finally, there is some water, let's install it first!" ”

Ye Zhizhi took a closer look and pointed to the water inside, "Second brother, this water is green, and there are many small creatures in it, if you drink this water directly, I am afraid it will make people feel uncomfortable, at least it will have diarrhea, and at worst it will be possessed by some parasites, which will kill people!" ”

Ye Yu was stunned, "Parasite? That...... Is that a not-so-good bug? ”

The sting also wondered, "What kind of worm is a parasite, why haven't I heard of it before?" ”

Ye Zhizhi covered his face and turned on the encyclopedia mode again, "Harm, it's similar to ticks, they are specially attached to other creatures, relying on the flesh and blood of other creatures to feed them, and even derive the next generation from them......"

With this explanation, everyone understood, and Ah Ping hurriedly stepped back, "Then this water can't be drunk, what should I do?" ”

"But it's okay for this little water dragon to drink...... Gu Yu looked at the little water dragon on the side who was sticking out his tongue and licking his mouth.

"It's not that you can't drink it, it's best to boil it and filter it before drinking! The little water dragon is different from us, its body looks like a lizard and a pangolin, maybe it is a creature from ancient times, and it used to eat this kind of thing......" Ye Zhizhi also frowned, in the desert, there is really no chance to pick and choose, "Second brother, you must fill this water alone, you can't go to other water sources to mix it, bring it back and let them boil it and drink it!" ”

Ye Yu nodded, "Then I'll only fill two pots of ......" to search for e-books

"There could be cleaner water up there!" Stunned looked up, "The vegetation above is higher, and the shadows seem to be larger......

He has been observing Ye Zhizhi's behavior, and he is as smart as him, and he immediately noticed Ye Zhizhi's secret to finding water:

First, the vegetation is dense and lush, which means that the surrounding water source is sufficient;

The second is that the stone is big and shady, according to Ye Zhizhi, it seems that the cooler and less light there is, the water seems to be "evaporated" more slowly.

I think the word evaporation means that the water is dried......

A few people climbed up a little more, and sure enough, the water source above was clearer, and there were no more muddy and small insects in it like just now.

When Su Dufeng saw such water, he immediately decided: "It's mountain spring water!" ”

After that, he took a sip first, only to feel extremely sweet and refreshed.

Everyone immediately took the kettle on their bodies and began to fill it with water.

Ye Zhizhi took off the kettle on his body and gave it to Ah Ping to load, and he touched the head of the little water dragon, and the little water dragon also rubbed her hand.

"Little one, would you rather come with me, or stay here?" She is very grateful to the little water dragon, if it weren't for the little water dragon, she might not be able to go on in the future.

The little one didn't understand her, but just screamed happily.

Ye Zhizhi smiled and made a plan for it: "You originally lived here, you helped me, and I still have to take you away, it's really unfair...... Stay here, little one, this is your home...... If I go back to the desert in the future, I'll come here to you, okay? ”

The little guy seemed to feel her emotions, and suddenly quieted down, and his two big black eyes were suddenly filled with tears......
