For this reason, Lao Fang racked his brains, thinking that with his knowledge, there should be some way, but he just didn't think of it for a while.

Physics?

Creature?

Chemistry?

Well, for a person who only knew how to play games when he was a student, this little bit of knowledge would have been returned to the teacher a long time ago.

……

Lao Fangcha didn't think about eating, and finally gritted his teeth and stomped his feet on the third day, and decided to come here ruthlessly - set fire to the mountain.

That night, when the wind was in full swing, the old party dispatched more than a dozen people and began to set fire to the area where the three-headed python lived.

The mountains and forests are dense, and the weather is also very sunny in the past few days, which causes the fire of the old party to burn extremely vigorously, and the fire is several zhang high.

The fire burned for three days and three nights, and even the mountain where the old man originally lived was burned to the ground, but fortunately, the old man originally lived in the crypt, so he was saved from death.

On the fifth day, the fire was almost extinguished, and the old party sent spies out for a walk, and the old party was happy.

Within a radius of dozens of miles, they were all burned by this fire, and all birds and beasts, and other populations were wiped out.

Those who did not outrun the fire were all charred and could not eat.

And the three-headed python is nowhere to be found, and I don't know whether it was burned to death by fire, or if it saw that the opportunity was wrong, and fled with its tail between its legs.

"The Tinder of Civilization!" The old man muttered to himself.

Then more than 40 adults and more than 100 children moved towards the valley.

Lao Fang looked at the "paradise" in front of him, and he felt a little crying and laughing.

The originally beautiful valley has now become a scorched earth, and the giant trees with a diameter of more than ten meters are still emitting smoke at the moment.

The breeze blew, and clumps of grass and wood ash were raised, mixing into the air, making it a little difficult to breathe.

Lao Fang sighed, the arson of the forest is indeed wrong with him, and he has no quality.

However, the old side also knows that this is only temporary, and by next year, everything will be fine here.

Soon, the old party decided to do some engineering.

Within a radius of dozens of miles, there were still many giant trees that had not been completely burned through, so Lao Fang decided to get some nearby.

Soon, he invented the copper saw (which was completely untechnically difficult) and made many more tools.

But it's a pity that these things, which were artifacts in prehistoric civilizations, are useless against such huge trees, and it is difficult to even brush a board, let alone sawn off a tree with a diameter of more than ten meters.

The old party had no choice but to give up this plan for the time being.

……

Due to the fire that burned the mountains and forests, this year, food was extremely scarce, but fortunately, Lao Fang still knew fishing, which allowed all the people to survive.

Because the fire has burned out the mountains and forests, even birds don't here in this area, let alone other carnivores.

This year, there were no insects, no birds, no flowers, and no shade in the valley.

In addition to the sound of rushing water, there is only the whining wind in winter.

Earthlings still live in crypts, only basking in the sun and blowing the wind in the valley during the day.

Many people's eyes are slowly returning to their normal luster, and only children who are born blind are still unable to see the light.

When I returned to the earth in the spring of the following year, nature felt sorry for this land, so patches of tender green emerged from the scorched earth, and flowers bloomed in the place where the dust and ash accumulated, and the branches stood in the wind in the stump and broken stem.

"Wildfires can't be burned, and the spring breeze blows and grows again!" On a whim, Lao Fang taught the children this poem.

"Wildfires can't be burned, and the spring breeze blows and grows again!" A crisp and milky voice mixed with a milky voice followed the reading.

"Hmmm! It's really time to teach these kids something! Lao Fang said in his heart.

So, Lao Fang began to teach these children to read and write.

"1,2,3,4...... Arabic numerals that must be learned.

"a,o,e......" initials and finals are taught.

"The sun, moon, mountains and stones, rivers, lakes and seas, flowers and trees, fish, insects, birds and beasts!" Cognition of natural things.

The children are very smart, no different from the children of the 21st century on earth, and Lao Fang is very pleased, he feels that he will definitely be able to pass the customs this time.

"Isn't it Pain VI!" Lao Fang is full of confidence, when these children are older, he will teach them some mathematics, physics and chemistry, and then let them develop freely, it is estimated that it will not be many generations before they can dominate this prehistoric era.

In addition to teaching children, Lao Fang also began to plant a large area, the area of the valley is not small, Lao Fang reclaimed dozens of fertile fields, and began to plant some wheat and millet.

In addition, the old side grows vegetables and fruits.

Although these vegetables and fruits are different from those on the earth, Lao Fang saw that the Xuanhuang people had eaten them for 20,000 years, so they were very familiar with certain vegetables and fruits.

The breeding industry was also put forward by the old party, and he hoped that the herbivore would come back as soon as possible, so that he could catch a few and raise them in captivity.

Life in the valley was very comfortable, and Lao Fang was proud of his wise decision.

Accumulate grain, slow to become the king!

What hegemony to strive for, silent development is the last word.

Lao Fang encouraged himself from time to time, he knew that he was now in a transitional period, and once he crossed this threshold, dominating the Xuanhuang Star was just around the corner.

With the presence of the commander of the old side, whose strategic thinking is at least a million years older than the current era, all the forces that stand in the way of the old side will not be worth mentioning, at least the old side thinks so.

……

In the blink of an eye, a hundred years have passed.

Compared to a hundred years ago, this paradise has changed dramatically.

Lao Fang put all his energy into this game,

In the blink of an eye, a hundred years have passed.

Lao Fang has really lived in this game for a hundred years, and there has not been a minute of acceleration, and not a second has been skipped.

For a hundred years, he devoted all his energy to this game, and every day, countless ideas came to him, and then he thought about whether he could make it happen.

The copper ore and gold ore have been consumed by him, the blades and armor have already been sufficient, and the grain reserves have been in a state of surplus.

He intends to build an invincible ironclad army, wrapped in bronze armor, to conquer the world.

He has raised a large number of cattle, sheep, horses and pigs, and the number is considerable, some as food, and some as transportation!

So far, the population under his control has increased from 50 to 3,000.

It can be seen how anxious Lao Fang was during these sixty years, and in order to maximize the population growth rate, he forcibly increased the reproductive period of females to about thirty years.

This crazy move has made the entire population reflect a kind of pathology, the rate of abnormal human beings is as high as 80%, and a series of problems such as frailty, disease, nervous decay, and intellectual retardation are becoming more and more serious.

The old party felt a headache.

He finally realized the disadvantages of inbreeding.

But he can't help it, these people's sowing methods are too messy, and he has no clue even if he wants to deal with it now.

Although there are weapons that are superior to the times, if you use these people to fight for hegemony, you may not be able to find the north before you go out.

"Hey!" Old Fang let out a long sigh and silently quit the game.

It really hurts to end it in this way.
