A gentle breeze blew through the corn fields in the wilderness outside the mountains, and countless golden ears swayed slightly, creating a burst of corn fragrance.

The endless yellow corn fields seem to show Lin Yuan that this is another bumper harvest year.

Lin Yuan stood on the back hill of Huadu, quietly looking down at the land under his feet.

Time flies, in a blink of an eye, more than a year has passed since the last victory over the scourge of the Jiuli tribe, and in this more than a year, it seems that the Jiuli tribe has not made any moves against the disappearance of the scourge, perhaps because the scourge is insignificant in their hearts, or maybe they focused their attention on the mountains and did not suspect that they came to the wilderness outside the mountains.

After all, the more than 10,000 displaced soldiers brought by the disaster were either killed in battle or stayed here, and none of them returned to the mountains, and no one knew what happened here.

It seems to be autumn at the moment, and Lin Yuan can't be too sure, because he doesn't have a calendar to record, but by feeling, the weather is getting cooler day by day, and the corn planted is also ushering in the harvest season.

After many seasons of farming, the current slaves have mastered the skills of planting, they improved the original stone spear digging ground, under Lin Yuan's design, they learned to make tools that combine wooden strips and stone tools, similar to the plough of later generations, but the structure is much simpler, and because the durability of the stone is poor, so every time they plow for a period of time, they have to replace the stone chips.

However, even so, it is much more efficient than the previous excavation and sowing of pit by pit, especially when Lin Yuan put into use more than fifty bison that had grown up and successfully domesticated, the slaves of the Yan tribe were finally able to successfully use the power of the beasts, put the plough behind the back of the herd, and further improved the production capacity of the cultivated fields.

The improvement of production capacity eventually led directly to the expansion of the planting range, and now the Yan people have completely opened up the swamps in the river delta area, and even expanded to farther places, where the river is farther away, the land is drier, and water needs to be diverted for irrigation, although the cost is huge, but Lin Yuan found that the corn planted there has a higher yield than the swamp.

Moreover, at the same time, Lin Yuan also found that the fields in the dry zone seemed to be more suitable for crops such as soybeans, and its growth cycle was shorter than that of corn, and the need for water was much smaller.

In addition to the large farmlands cultivated by slaves, in the hills, in the bays, in the open spaces in front of the hunters' huts, and around the livestock pens, people everywhere planted in their spare time, soybeans, this tenacious plant, very smoothly overcame the harsh natural conditions of ancient times, multiplied rapidly, and made a great contribution to the food supply of the tribe.

For Lin Yuan now, he no longer has to worry about the food of the tribe, just as he convened the leaders of the tribes a year ago, Lin Yuan fulfilled his promise, successfully let the Shennong, Bai, and Tu tribes stay in the wilderness, and retain the characteristic culture of their own tribes, taught them how to farm and raise livestock, and helped them establish their own small settlements on the plains.

Perhaps in the nostalgia for their hometown, the Bai and Tu tribes chose to settle their new settlements on the south side of Huadu, near the mountains and valleys, while the Shennong tribe, under the leadership of Fuxi, found another way, went the opposite, along the Jing River all the way north, and established a small camp 2,000 steps north of Huadu, where it had not been cultivated by slaves, and was surrounded by a pure and original wasteland, overgrown with weeds, and they thought that there were more unknown herbs to be found.

"Since fate has brought us to the wilderness, we are to obey God's will...... ......"This is the last word left by the old chief of the Shennong clan to Fuxi before he died, the old chief died soon after the Chinese defeated the calamity, because of old age and decay and the torture of the calamity.

With the help of Lin Yuan, Fu Xi led the remnants of the Shennong tribe to build their new camp in a short time, and soon put the tribe's life back on track, and the people overcame the pain of the past, turned their grief into strength, and built a new home together. Fu Xi buried his father's body on a hill in the new camp, and although the old chief of the Shennong tribe did not see it with his own eyes, he would always lie here, guarding the new home of the Shennong tribe in the wilderness.

After everything in the Shennong tribe was settled, Fu Xi handed over the daily affairs of the tribe to one of his most trusted henchmen, and returned to the Fire Temple in Huadu alone, and he said to everyone, this is my final destination. Not long after, under Lin Yuan's instructions, Fu Xi built a small holy fire altar in the camp of all the clans on the plain for everyone to worship.

At this point, on the Shanbei Plain, there were six tribal alliances headed by the Yan people, and the rest of the tribes were the Suiren clan, the Huaxu tribe, the Tu tribe, the Bai nationality, and the Shennong tribe, all of these five tribes obeyed the orders of the Yan tribe, and all their male primitives of school age unconditionally obeyed the deployment arrangements of the Yan people, and in return, they could accept the military protection and support of the Yan people free of charge.

The first tribal alliance on the plains was finally successfully established, and the shadow of a civilization began to take shape.

……

"Flame King!"

A crisp and pleasant female voice came from behind Lin Yuan, interrupting his contemplation, he hurriedly came back to his senses and gently took the person into his arms.

"Nasty! What are you doing...... Be careful that there are people here......" Anna said shyly, she struggled hard, trying to escape from Lin Yuan's powerful big hand, but she was unsuccessful, and after pulling a little, Lin Yuan let go of her arm.

"It's not like you're going to pounce! How~ What, do you want me to dodge? Oh, I know, I'll make you pounce next time......" Lin Yuan smiled evilly.

Anna's little face was red and white, and she said coquettishly: "Poor mouth again...... You, you, this mouth is the most powerful......" At this, Anna's face turned red again, and then she continued: "Get down to business! The Huadu City Wall you designed last month, they seem to have done it almost, I want you to come over and check it out, do you have time? ”

Lin Yuan stretched out his hand, hugged Anna's little waist hard, and then ran away with a wicked smile, saying as he walked:

"Go! Lord Anna, the deputy patriarch of the Yan clan, came to invite me personally, how dare I not obey ~ haha......"

Anna's little face turned red again, and she gasped and trotted all the way over.

The so-called "city wall" that Lin Yuan let the industry do, it seems, is actually a higher fence, subject to the limitations of the current productivity, it is impossible to open the mountain to take stones, and naturally it is impossible to make a towering stone city wall, so the industry can only follow Lin Yuan's requirements, the wood drifting down from the valley is chopped into a wooden stake little by little with a stone axe, and then reinforced with rattan around, and in the gap between the wooden stakes, the gap can be filled with waste wood and bark. It is necessary to build a large number of fences in succession to enclose the whole of Hua Du.

However, fortunately, there are enough Yan slaves at present, especially after the use of bison and other livestock, and a large number of farming slaves have been released. It took them about a month to complete the spectacular-looking circular wall.

Lin Yuan, accompanied by Ye and Anna, walked around Huadu, he carefully inspected the structure of the fence, the stability of the rattan at each junction, and the solidity of the stump, etc., and finally, after about the time of a torch, they finally turned back to the starting point.

"Well...... Not bad! Well done! Lin Yuan nodded with a little satisfaction, Ye exhaled a long breath, looking at King Yan's serious face along the way, he didn't know if the leader was satisfied nearby, and when he heard Lin Yuan's affirmative voice, he was naturally relieved.

"But...... Our fence is only half finished......"

"Huh? Halfway? Anna and karma asked in unison, especially karma, his eyes widened, he looked left and right at the wall beside him, and said in confusion:

"The Flame King...... Didn't you just go around in a circle, and according to your instructions, it was all built......

Lin Yuan shook his head with a smile, and he said:

"Yes, the fence has been built, but the wall of our Huadu is indeed only half ...... built" As he spoke, Lin Yuan bent down and picked out a relatively flat stone from the pile of rubble behind him, put it on the outside of the fence, and then took another piece and put it on the inside of the fence, and then continued to use stones to build it up alternately on the inside and outside.

Seeing this, karma hurriedly summoned the slaves and Lin Yuan, imitating their chieftain, and began to build up stones, and after a while, the stones on both sides were built along the wooden fence, and finally covered the fence, and from the outside, a small section of the stone wall was born.

"Ah...... You mean, King Yan, ...... with stones? Ye Yi patted his head and asked excitedly.

Anna frowned and said:

"This can't be done, although there is a wooden fence to support it, but you see, this stone is so loose on top of it, and it will come down with a pull of your hand......" After speaking, Anna stretched out her hand and gently pushed the top stone, and a small stone fell in response.

Lin Yuan shrugged his shoulders helplessly and said, "You, you're always so anxious, I haven't said it's done yet......"

Then he turned and searched, and then took two steps, and found some undried clay around the fire-making pits that were everywhere on the outskirts of the city, and he did not care about the dirt, and he bent down and dug with both hands, and took a pile of clay to the wall.

This time, Ye had already made preparations, and before Lin Yuan got up, a large group of slaves under his command, imitating Lin Yuan's every move, moved a large amount of clay and mud, and pasted it on the stone with Lin Yuan, and ...... Double-click......

After a while, with the joint efforts of everyone, the mud was smeared and covered with the stone city wall, and finally the stone was completely wrapped inside, and then Lin Yuan began to instruct the karma one after another, let the slaves continue to paste the mud up, continue to thicken, and focus on strengthening the bottom of the wall, making a trapezoidal shape with a wide bottom and a narrow top.

As the mud smearing project ended, Anna suddenly realized:

"Oooh oh...... So that's the case, King Yan, you have to make an earthen city wall! Like in our hometown village, adobe walls? “

Lin Yuan smiled mysteriously and said:

"No, what I'm going to do is a stronger wall than that, the kind in our hometown, made of adobe, which will be eroded by wind and rain over time, and is not suitable for defense...... However, this wall is reinforced with mud on the outside, a stone foundation on the inside, and a solid wooden fence in the middle as a support, which can not only save the amount of stones, but also further expand the scope of the wall......"

"But...... Won't the wooden fence rot and collapse? Anna asked reluctantly.

Lin Yuan smiled and said:

"Don't you know that there is a mantra called dry for a thousand years, wet for a thousand years, and not dry and wet for decades?"

Karma and Anna were stunned, and the latter asked, "What does this mean?" ”

Lin Yuan scratched his head and said, "Haven't you heard of it in your hometown?" It's a mantra that every carpenter knows......"

Anna had a black line on her face and said, "Not everyone has ever worked as a carpenter...... Have you done it? ”

Lin Yuan smiled, "That's not it, I learned it in a carpenter's role-playing game, this is the permanent hint in the loading interface of that game, what he means, that is, for wood, if it is soaked in water, or if it is absolutely dry, the wood itself will naturally carbonize, and it can be kept for up to 1000 years, but if it is placed in a natural environment, it will be wet with rain for a while, and it will be dried again, then it will rot quickly...... Therefore, our fence should be strictly sealed with mud on the outside to ensure that the inside is absolutely dry and isolated from moisture, so that it can naturally not fall down for a long time! ”

Hearing what Lin Yuan said, Anna couldn't help but nodded, and muttered, "It turns out ...... There's so much to learn by playing games......"

And Ye just stood stupidly on the ground, waiting for Lin Yuan's next order, for karma as a primitive person, he naturally couldn't understand what Lin Yuan was saying, but out of respect for the leader, he still stood aside respectfully.

"Alright, alright! Don't stare at me like a monster, that's it, karma, remember to arrange slaves, you have to carefully paste the mud, by the way, don't mix it all with clay, mix it with ordinary loess, and add some minced corn straw to help extend the life of the mud. ”

Ye hurriedly received the order, called a large number of slaves, and began construction.

"What are you looking at me for?"

Lin Yuan said as he walked, looking at Anna beside him again.

Anna followed behind Lin Yuan, grimaced, and said mischievously:

"Oops...... Lord Yan, I sometimes ...... I really can't guess, how can you have so much knowledge in your head, did you learn it all in the game? How can I not believe it? ”

Lin Yuan squinted at Anna, and his appearance couldn't help but laugh.

"What's the matter? What do you think? Lin Yuan replied to Anna in a rhetorical tone, making Anna's expression cute.

"Humph! If you don't say forget it, I see, you are just a blind cat touching a dead mouse, just lucky, how can you know these truths? ”

Lin Yuan suddenly stopped, looked back at Anna, smiled slyly, and said:

"What if I had another golden idea?"

Anna looked at Lin Yuan differently, and the latter pointed to a slaughterhouse on the outskirts of Huadu, where meat and food were supplied to the Yan people, and the hunters of the Yan Alliance occasionally hunted and sent back from the wilderness, as well as wild boars that reached the slaughter standard or bison that had lost their labor, etc., were slaughtered here, cutting fur and cutting meat pieces.

What appeared in front of Lin Yuan and Anna's eyes was a batch of animal skins hanging on rattans, one by one waving in the wind, ready to be dried.

Lin Yuan smiled and pointed to one of the cowhides and said:

"Thank you for the reminder, and for giving me another flash of inspiration, how about I invent a new use of cowhide for you?"
