Jin Mang pursed his lips and silently followed his parents.

For her, who is only two years old, it is not impossible to walk more than ten kilometers alone.

——In terms of physical fitness, Jin Mang is truly blessed, whether it is strength, physical strength, flexibility or reflex nerves, she can be proud of the others, and she is the kind of person who can outperform most people who insist on exercising in all aspects even if she does not insist on exercising.

And in this life, her physical fitness is better than in the previous life.

But the premise is that she doesn't need to keep up with Qingfeng and Qingsui.

Even if Qingfeng and Qingsui stopped to wait for her from time to time, Jin Mang had a hard time following, and when she saw her own cave, her legs fell to the ground weakly, but she couldn't get up.

Qingsui put down the prey, picked up her daughter with some distress, and said with a smile: "Mangmang is acting very well." ”

You must know that she and Qingfeng have considered giving up some of their prey for Mangmang.

But unexpectedly, the kid persevered.

Jin Mang gasped for breath, and when he recovered, he got off Qingsui, ran to the lake, knocked open the thick ice, poked his head out and began to drink water.

The lake is very cold, but it is very refreshing for Jin Mang, who is sweating too much during exercise.

- She actually thought about letting Qingfeng and Qingsui develop the habit of drinking cooked water, but she quickly gave up, they didn't have that condition. The jar made of the eggs of the birds is sturdy, but it cannot withstand heat. The only way humans in Anze can heat food is by roasting, and there are no pots or pans at all.

By the time Jin Mang had completely recovered, Qing Feng and Qing Sui had already processed their prey, and then kept splashing water to make it form a thick layer of ice on its surface, and then hung it at the mouth of the cave.

In the days that followed, Qingsui began to teach Jin Mang how to handle prey and tann hides.

"Most of the time we don't eat prey offal, because we humans don't eat raw like other beasts, and the taste of offal after roasting is ......" Qingsui frowned, "But in fact, compared to meat, offal is actually more nutritious and can provide more strength for our body." So when the splitting season starts to be insufficient, no matter how unpalatable the offal is, we have to eat it, and what I'm going to teach you today is how to treat the guts of the prey as much as possible to make the taste more acceptable......"

No matter what Qingsui taught, Jin Mang studied very seriously.

She didn't know the full picture of the split season, but now the extremely low temperature had made her feel a sense of crisis.

Because many animals do not hibernate, such as squirrels and hares, which are also unusually active in winter, the Jinmang family did not run out of food.

But even so, the mouth of their cave was covered with meat frozen in ice.

Qing Feng went out again for some reason, this time it wasn't as long as the salt change, he came back in only five days, holding an arm-thick piece of wood, there was no injury on his body, but he looked very embarrassed, and his eyes were tired that could not be mistaken.

Jin Mang's gaze couldn't help but fall on the piece of wood, and after hesitating for a moment, she spoke: "This is...... Iron-based trees? ”

The reason why I can recognize it is because there is a knife at home that is made of iron-based trees, and Qingfeng and Qingsui will use that knife to deal with prey on weekdays, and Jin Mang has also been used under Qingsui's supervision, which is very sharp and easy to use. If it weren't for the fact that the knife was too small, it would definitely be able to get twice the result with half the effort when used in battle.

However, Qingsui told her that iron-based trees are very rare, and the knife in her hand was still an adult gift given to her by her mother at that time.

Qingsui's expression was not surprised, obviously she knew what Qingfeng was doing when she went out.

In fact, in order to be able to get this piece of iron base wood, they have been planning since before they became adults, and the reason why they settled in the current territory is probably because of this.

Seeing her daughter's surprised face, Qingsui smiled and explained: "In fact, although iron-based trees are rare, they are not uncommon. It's just that the iron-based tree can't be broken easily because of its own hardness, and it needs a special underground flame melt to cut it off little by little. It took you and your father three years to save up enough molten liquid. ”

Flame melt?

Jin Mang felt that the word was somewhat familiar, and after thinking for a moment, he remembered that he had once explored along the interior of the cave, and saw a stone stalactite that shone with orange light, and transparent red water dripping from it. Just as she was about to touch it with her hands, Aoho appeared to stop her, warning her not to touch the molten flame.

"Is it the molten liquid under the cavern?" She looked surprised.

Qing Sui nodded, "The temperature of the flame melt is extremely high, and it is the only existence that can intercept iron-based trees. ”

Jin Mang tilted his head and said strangely: "What should you use for the Yan Melt?" ”

"Of course it's a molten stalactite." Qing Feng smiled lightly: "When I started a family with your grandmother, your grandmother gave your grandmother a knife made of iron-based trees and a vessel made of molten stalactites. ”

As he spoke, he pulled out a strange ...... The bowl, to be precise, was a molten stalactite shaped like a bowl.

Since obtaining the iron-based tree, the frequency of hunting for Qingfeng and Qingsui has decreased slightly, and a large amount of time is allocated every day to forge the iron-based tree.

Jin Mang watched the whole time, and they made the iron-based wood into a long stick and a short knife slightly longer than a dagger.

She was amazed that the iron-based wood looked like wood, but it was essentially no different from metal, and it could be forged at high temperatures.

Even iron-based wood is much easier to use than real metal, after all, as far as Jin Mang's cognition goes, those weapons forged by primitive methods in ancient times are simply not comparable to modern weapons.

And Qingfeng and Qingsui didn't even have an iron furnace when they forged, and the forging skills could be said to be unskillful, but the long sticks and short knives they forged were no matter how simple the appearance was, but the hardness and sharpness were no worse than the modern cold weapons she had seen.

Just as Jin Mang was concentrating on watching Qingfeng and Qingsui forge weapons, she didn't notice that the climate outside was getting colder and colder, so cold that it was rare to see animals outside, as if the animals that had not entered hibernation abnormally before were her hallucinations.

The family began to eat the food they had stored before.

Qing Feng and Qing Sui's cooking skills are extremely primitive, and for those meat that is frozen in ice lumps, they directly take it to the fire and roast it, and the process is ......

After the ice melted, the water droplets fell into the fire, and the fire was small and large, and thick smoke came out, and the meat that was roasted did not know whether it was roast or bacon.

It's just that Jin Mang didn't care about that, she didn't expect that it would take two hours to roast a meat, and she was about to starve to death.
