From Duoduo and 77's comprehensive calculation of the light, tides, topography and landform of Taoyuan Star, surface evaporation and atmospheric circulation, the general monsoon circulation, frontal cloud system, and then the swirl on the surface of the mountain are inferred! Spoiler!

Based on the interference of different types of wind on sound, the type of wind is judged and the general position is inferred.

Qingxue has finally solved the problem of getting lost! All he had to do was stay where he was and say "Da!" on all sides. Da! Voice. Duoduo and 77 can help him find his position, and of course it is better to stand on a high place to reduce distractions. Because the presumed position in this way is inherently inherently incorrect, and if it is interfered with, the error may be unusable.

But even so, it didn't give Qingxue too much courage to climb the mountain!

When it came to the so-called darkest time before dawn, even many nocturnal animals went back to rest, and Qingxue mustered up the courage to climb the mountain!

Of course, he didn't wait, he used the mouth of the poisoned fish to cut off a piece of poisonous aquatic weed! Find a branch and carefully wrap the poisonous water weeds around it.

It can't be seen in the water, but it can be seen clearly on the land, and the poisonous aquatic weeds will seep out green liquid and have a strong smell when they are slightly entangled! Qingxue thinks that the big frog can be so big because of the smell, and this smell means poisonous! Since you can't make yourself strong enough to kill the enemy, let the enemy not dare to eat yourself!

Qingxue took this rod entwined with poisonous weeds and carefully stepped on land!

According to Duoduo's calculations, he needs to climb to a height of about 300 meters along the windward slope, then turn around, and travel 3 kilometers! After that, going down the mountain with the wind side is the most economical route for comprehensive work!

In the mountains, Qingxue has encountered predators a few times, and they are all hiding very carefully, and Qingxue has not noticed them! But their sense of smell was too sensitive, and they escaped from the ambush site by the poisonous weed sticks brought by Qingxue!

Qingxue was shocked! Oops! How can a big man pop up over there! This is still one! Oh, there's still one in the tree!

It's good to come out with this! Imagine that their sense of smell is 1,200 times stronger than their own, and they will be hurt by this smell 1,200 times worse! Thinking about it like this, Qingxue feels in good spirits! What a little bit of smell I suffer!

Some squirrels have fallen!

I've never had a chance to eat it, Qingxue picked one up, but Qingxue's teeth weren't strong enough to tear open the skin! I had to discard!

"Attention! Knock stones on each other and see! "Snow Pea suddenly came with instructions!

Qingxue didn't understand what she was doing, but she did it!

"That's it! The rock type and echo comparison analysis is complete! This mountain is supposed to have been formed after a volcanic eruption! A small eruption in a huge basin! And then where we are at the moment is a distant lava flow, which cools down to form this mountain! Stretch down the ridge to a long distance and you can find the crater! "Snow Pea Road.

"If you find the crater, what's there to eat!?" Qingxue asked excitedly.

"Oh, no!" Snow Pee replied.

"And who's going?" Qingxue said dissatisfied.

"Actually, the advice given by 77 and Duoduo is to go back to the river! Because this lava flow goes all the way to this point, stopping at the river, then there should be obsidian produced by the sudden cooling of the lava by the river! Can be used to make knives! Snow Bean suggested.

"Oh?" Qingxue is curious!

"For example, the rodents just now, with a knife, you can cut them into small pieces and eat them!" Snow Pea Road.

"Good! In order to eat! "Qingxue has decided! Go back and find that obsidian!

"What are you looking for?" Xuedou asked when she felt that Qingxue hadn't moved far.

"I'm looking for the guy I just lost! I thought I couldn't eat it, so I lost it! Now I've lost a meal of meat! Qingxue said in annoyance.

Qingxue, who didn't find the squirrel, returns to the river and starts exploring the obsidian that Snow Bean told him! Quickly found by tapping, several. According to what Snow Pea taught, smash it open! Sharp edges appear on the shattered stone!

By this time, the sky has already begun to lighten!

Regardless of fatigue, Qingxue wrapped the smashed obsidian fragments with non-toxic ordinary aquatic plants, tied a knot and carried it on her body! Go back and continue your climb!

This time he walked much faster than before, and the previous time he was afraid and cautious. Now he knew the power of the poisonous aquatic weed stick in his hand, and he had no fear!

However, to the mountain jungle higher than before! Some lemurs that live in groups in trees, they throw them with stones far away from the snow!

Hey, these guys are so nasty!

Qingxue quickly detached from their activity area!

When he climbed to the top of a tree, through the echo of the call and the direction of the wind, Snow Bean gave instructions that he could turn!

However, Qingxue is in trouble! He's thirsty!

Qingxue, who is more accustomed to swimming, has been running around on land for a long time, and thirst is already a serious problem!

Yuki also noticed that Qingxue's body temperature was abnormally elevated! But although they can search for many kinds of plants that can quench their thirst on the earth, in Taoyuan Star, the appearance of plants is not exactly the same! Through the sound echo, it is possible to analyze the general appearance, but it is impossible to judge the internal structure, let alone the analysis of toxic or harmful!

So Qingxue came up with a way by herself! Eat those gnawed leaves or bushes! Since other animals eat this, at least it should be a big mistake to eat it yourself!

With a little relief, Qingxue continues to move on!

Suddenly, I saw a small puddle of water in front of me! It's clear! Qingxue was just about to rush over to drink water!

"Stop! Don't go there yet! Scream more! Snow Pee reminded.

The snow shines!

"There's danger there! Although the water is very clear, it is confirmed by echoes that there is no grass growing nearby! Even the animal footprints only went over there, but they didn't leave! There's something wrong with that water! Snow Pea analyzed the echo of Qingxue's call.

Qingxue is really a little uncomfortable, I am already thirsty to see such clean water! But Snow Pea's warning is also very scary!

Qingxue climbed the tree and threw stones at the pool!

Ding-dong!

"It's very clean water! It's definitely much better than the water in the river! Qingxue said unwillingly.

"The water may be fine, but it's not safe there, there may be something else! It's better not to go over! "Snow Pea Road.

Qingxue observed the problem that Snow Bean said that not an inch of grass grows! That's true, but unlike poison, if it's poisonous, not a single inch of grass grows! It will show that sparse plant growth will begin to grow in the distance, and more and more farther away until it returns to its normal state!

This waterhole seems to have a strip 30 centimeters wide, and there is a small amount of moss in this width, and out of this area, the plants are normal!

Qingxue found a long branch, untied the small bag containing obsidian, poured out the obsidian, and used the long branch to hang the small bag to get water!

Nothing happened quietly around!

Take out the water, Qingxue took a sip, it's delicious, no problem! I'm getting ready to pounce!
