For those seriously injured, Gu Guo carefully cleaned the wound with low-concentration salt water, and then soaked a piece of clean animal skin in high-concentration salt water for a while, and tied it to the wound.

He touched the foreheads of the wounded, the hot temperature coming from the back of their hands. In this case, a fever is a good thing, indicating that the body's immune system is fighting, and when the fever subsides, either the person is cold, or the germs are cold, and Gu Guo can only do his best to obey the fate of heaven.

And those lightly injured are easier to do, after cleaning the wound with animal skins and salt water, they will use some unknown herbs to tie the wounds, listening to the people of the two tribes, this herb can be used to stop bleeding, Gu Guo nodded, thinking that there will be a chance to study and study it in the future.

After doing all this, he returned to his mother's side and found that neither his mother nor the stone had very good faces.

Gu Guo greeted him and asked, "Mother, what's going on?" ”

"They were robbed, and all the food and hides for the winter were robbed by a tribe with long yellow hair. Many of the two tribes stayed in the cave in order to hold back the yellow-haired people so that they could escape, and none of them escaped. ”

"Yellow hair? How many of them were there and with what weapons? Gu Guo hurriedly asked.

How strong is it to be able to fight two huge tribes with a population of more than 100 to escape, and have no ability to resist? Gu Guo felt that his tribe could defeat the two tribes in front of him, but that was based on the premise of bows and arrows and abundant food.

If it weren't for the superiority in numbers and weapons, how could it be possible to defeat the largest tribe formed at the limit of productivity in this era?

"Licorice said that the yellow-haired people came into the cave at night, and the night watchman was killed before he could react, and the yellow-haired people were going to take advantage of the sleeping people in the cave to quietly move the food, but their movement was too loud and woke up the sleeping baby, and then the tribesmen woke up and fought with the yellow-haired people."

The mother pointed her finger in one direction, where a woman in her thirties, who had escaped as a priest from one of the two tribes, was sobbing quietly. According to the mother, the son of Licorice went with the men and never returned.

Another tribe had a similar encounter, first being attacked by night and then sparking a major war.

Licorice said that the yellow-haired people would throw out some branches, which were so powerful that they stabbed into the people's bodies at once. I've seen licorice show me branches, and they resemble our arrows. ”

With that, the stone picked up a straight branch from the ground beside him, one end sharpened and stained dark red with blood, and the other end had no tail feathers and no groove to fit into the bowstring.

"I asked the birch to try to shoot this kind of arrow, but it is not as good as the arrow you made, it can't fly far and starts to roll, unlike our arrows, even if they fly far away, the arrow is still facing forward."

Gu Guo nodded, and half of his hanging heart was put down.

"How many people are yellow-haired?"

"Not much, much less than the people of our tribe, otherwise we wouldn't have been able to escape."

Licorice saw that the tribal leader and priest of Gu Guo were communicating something with a young boy, and came up out of curiosity. The leader and priest of the other tribe took the lead when the two groups of men fought, and the daughter of the dead priest leaned in with red eyes.

"What are you going to do next?"

Gu Guo opened his mouth and asked, losing food and shelter, and carrying more than a dozen wounded, the people of the two tribes were afraid that it would be difficult for them to survive this winter.

"I ...... We...... Woo woo woo ......" Before the priest's daughter could say two words, tears the size of beans slipped from the corners of her eyes.

"Huaihua, people can't live anymore, don't cry." The mother comforts the girl named Sophora with barren words.

"Why don't you come with us?" After Gu Guo finished speaking, he glanced at licorice and acacia flowers.

Licorice and Sophora were stunned, and an imperceptible crimson flashed across Sophora Flower's face, which was hidden by her crying red eyes. Shi and his mother also looked at Gu Guo in some surprise, the two glanced at each other, nodded understandingly, and showed an expression that adults understand.

How could all these actions escape Gu Guo's eyes, he felt a little speechless, his plan to develop the tribe seemed to be distorted by some people.

"We have a lot of food to survive the winter, and we're going to build houses in the future, and when it snows, we don't live in caves." After Gu Guo finished speaking, he stood up, he was going to burn some broth for this group of confused and panicked people.

"The house?" Licorice read this word that she had never heard before, and Sophora also listened intently on the side.

"Coo-goo, people with black hair and black eyes all have the same ancestor...... Once upon a time...... "Mother retold the story Gu Guo told the night before.

The people of the two tribes sat around their mother like this, and they drank the broth that Gu Guo had cooked. Since there was only one clay pot and two hundred mouths, the people of the two tribes only drank one or two mouthfuls of broth each, and as for the meat slices, they were distributed by Gu Guo to the dozen or so wounded.

When Shi said that in their tribe, they could drink broth every day, and the people of the two tribes burst into tears one by one, and this winter, they would not be exposed to the wilderness.

At this moment Birch came over with a large brown bird in his hand, which looked a little like an eagle and a little like an eagle. In the other world of primitive times, there was no such thing as animal protection, and the tribesmen naturally tried to use the tools at hand to increase their food reserves.

Gu Guo ran over and took the big bird in Hua's hand, feeling five or six pounds, an arrow was inserted in the chest of the big bird, he didn't expect that the bow he made could shoot the eagle, and he couldn't help but glance at Hua.

Licorice and locust flowers were stunned, they would never have dreamed that the birds soaring in the sky would now become the food of the clan!

But when they saw the arrows pulled out by Gu Guo clearly, there was a look of fear on their faces, their sons and mothers were killed by this kind of branch!

"Stone, what is this?" Licorice plucked up his courage and pointed to the arrow in Gu Guo's hand.

"This is an arrow, shoot it with a bow." Shi Shi took the bow from his back, took the arrow from Gu Guo's hand, skillfully wound the arrow, and aimed at a small tree the thickness of a thigh more than ten meters away.

"Whoosh!"

When the arrow left the string, and the eyes of the licorice and locust flowers still fell on the bow, the arrow was already driven by the elastic potential energy and firmly nailed to the trunk of the tree.

"Bows and arrows, they were conceived by Googo." The stone handed the bow and arrow to the licorice and the locust flower, and asked them to touch the bow and arrow to dispel the fear of death, "With the bow and arrow, we can catch up with the amount of three or four days of hunting for one day." ”

"And this piece of stone on the arrow, I came up with it!" Hua ran over and said, he remembered his dream, and couldn't help but worry about the safety of the tribe, his little niece was still in the cave!

"Goo, did you think those yellow-haired people would come to our tribe to steal food?" Birch asked in a low voice.

"No, the tribes of licorice and locust come from the north, and the yellow-haired ones come from further north. Our tribe is in their south, plus those yellow-haired people have already robbed the food of the two tribes, so it shouldn't come out when it snows this time, but it won't be the case next time it snows. ”

Gu Guo replied, his words were a little appeased, but now he had not built a defensive position, and the number of enemies was unknown, so he could only brake quietly.
