When it comes to fighting with people, Gu Guo is definitely inferior to these people he picked. In this era, as long as an adult male is basically a pentagonal warrior, asking him to teach primitive fighting skills is simply a big knife in front of Guan Gong.

In ancient wars, the quality of soldiers was nothing more than knowing the flag and obeying orders, the formation was neat, the advance and retreat were measured, and the soldiers were skilled. In this era when bronze and iron tools did not appear in the army, the quality of individual soldiers almost determined the victory or defeat of a battle.

When everyone is a seasoned hunter and on the same page, discipline becomes the key to the balance of success or failure.

Pigskin came running early the next morning to tell Gu Guo that he had already met the people in the team. Gu Guo did not immediately arrange training tasks for him, and the tribe could not afford to raise more than forty full-time soldiers for the time being.

He asked the pig to take people to the Tao River to fish, at this time the surface of the Tao River has formed a thick layer of ice, the pig skin led the team, a group of two to push the birch bark boat to the center of the river to dig a hole, although it is not as good as the previous interception in the Ji water to block the fish, but the harvest of dozens of catties a day also made the tribesmen happy.

For the remaining twenty people, Gu Guo arranged a detailed training plan.

On the first day, he lined up the twenty men, and he told him to form the team into two rows of ten men each.

Camelina responded to the call, but Gu Guo overestimated the clansmen, and saw that the twenty people in front of him were distributing the team according to their usual relationships, generations, and clans, even if there were only twenty people, they were in a mess.

Gu Guo didn't speak, walked a rope from Huaihua, walked in front of the camelina, and straightened the rope.

"Camelina! You're the captain, you're the first to stand! ”

"Stand in a row by tall and short and don't put your feet above the rope! The same goes for the second row! ”

The chaotic laughter and frolicking finally had a little order, and the clansmen spent at least five minutes pushing and shouting about their height, and finally two rows of sparse teams stood in front of Gu Guo.

Gu Guo didn't complain about the clansmen, it was easy to pull eggs when the steps were big, the rice had to be eaten one bite at a time, and the team had to be lined up one by one.

Even in their previous lives, students could not immediately line up the ranks under the influence of military TV dramas and movies, let alone these primitive people who couldn't read big characters?

"You remember where you are standing now, remember the people around you, it will be the same queue to gather here tomorrow morning, and those who stand in the wrong place will not be allowed to eat dinner!"

Gu Guo said it very loudly, and he wanted to make sure that everyone present could hear it.

"Did you hear me?"

"Clear......

More than a dozen responses rang out in the queue.

"I can't hear you louder!"

"Clear."

"Louder!"

"Clear!"

"In the future, when you line up, you have to speak loudly, you know?"

"Got it!"

Yu's last few words were roared, the momentum was there, and the waist pole was straighter than before.

In the morning, Gu Guo was teaching twenty clansmen to stand in a military posture, and the two rows of people stood neatly, as if there were twenty wooden stakes on the flat ground. The women weave rattan shields on the side, and with the experience of weaving nets, they weave very quickly.

The twenty shields were completed in only one morning, and Huaihua looked at the work in her hand, and she used red paint to paint a small clay pot on the side of the shield handshake, which was given to her by the camelina when she was digging in the soil, and contained a small piece of soap, which was very fragrant.

In the afternoon, Gu Guo tied several straw figures with straw piles and wooden shelves, placed them in a queue 30 meters away, and required each person to shoot 20 arrows to end the day's training.

At dinner in the evening, Gu Guo redistributed the houses for these twenty people, and eating and living together could better improve the tacit understanding between comrades-in-arms.

As for literacy and arithmetic, he also taught them in the evenings.

So there is always a sound of "one plus one equals two, one plus two equals three...... and "ahh......h

And the children of the tribe were also led by Gu Guo to stand in line with them, but most of the time they spent learning the four arithmetic and literacy.

The characters taught to the clansmen were simplified characters, and Gu Guo didn't think he had the ability to create a new hieroglyph according to the gourd painting, mainly because he didn't want to learn it again.

Arithmetic is relatively simple, and the children's receptivity is good, and they can basically learn to add and subtract within 20 within a month, which is already the level of the first grade of primary school in the previous life.

A few have already started learning in-table multiplication, including Kaede, of course.

With Gu Guo opening a small stove before going to bed, Xiao Feng's learning progress is naturally ahead of other children.

Now, Xiao Feng can understand how big the number of 365 days in the story that night is, and with the vertical calculation method, she no longer has to use her finger as a decimal tool, she can only use a wooden stick to write a few times on the mud floor to come up with the answer.

"One thousand, ten thousand, ninety-nine thousand, nine hundred ninety-nine...... Brother, what's next? ”

Xiao Feng tilted his head and wrote the Arabic numeral 99999 on the dirt floor.

"It's 100,000."

Gu Guo touched Xiao Feng's smooth ponytail. Since the advent of soap, the hair of the tribesmen is no longer as oily as hay, and the men have tied their hair, while the women have tied some ponytails and some have learned how to weave nets and braided them.

Feeling his hair being stroked, Xiao Feng giggled.

"Brother, I know! After 100,000 is million, after 10,000 is 10,000,000,000,000,000,000 after 10,0 ”

Xiao Feng shook his head and drew a long string of one and zero on the ground, but he heard his brother say: "Ten million is after ten million." ”

Kaede: "Huh? "I seem to understand it, what is after 100 billion?

The little girl shook her head like a rattle, and she asked her brother, who said he didn't know.

The number of 100 million is too big, Xiao Feng feels that she will not be able to count such a big number in her life, after all, there may only be more than 300 days a year!

She drew a small figure on the ground, in the style of a stickman, and then wrote the number 253 after the figure, which is the number of clansmen. Then he drew a stick figure of a small fish underneath, and the number 34 was written on the back of the small fish, which was the number of fish caught by the pigskin team today.

"How many fish do you get for each person?"

"It seems that I can't get a single one!"

"But the people can eat fish every day!"

"How is this calculated?"

The little girl grabbed her scalp, she was very distressed, she was already ahead of all the children in the tribe, and every night there was her brother teaching herself, but she couldn't even calculate the problem of eating every day.

The girl's self-esteem made her tears flow uncontrollably.

Gu Guo cried when he saw his sister drawing on the ground, and quickly turned around and hugged his sister in his arms.

"What's wrong with Xiao Feng, is there anything uncomfortable?"

"Brother, I can't figure it out, woo woo woo ......"

“？”

"There are 253 people in our tribe, and Uncle Pigskin led people to catch 34 fish today, and we obviously ate fish at night, but why are there no fish?"

Gu Guo glanced at the numbers on the ground, and then scrutinized Xiao Feng's words, he suddenly realized that his sister had been exposed to the practical application of division.

"Xiao Feng, this has to be done by division, the last method of the four operations! Come, let my brother teach you. ”
