The maple leaves are red, and autumn has arrived. Erlong eats little, but it is also a family of three, and it must reserve more food for the winter and next spring. 'Big Tiger' likes to go out with Li Dawei, hunting is playing.

Guarding near the salt mud field, the probability of encountering prey is high, and the two brothers have a tacit understanding that one person chases one, but chases, does not dig traps, and does not cooperate with fishing law enforcement.

Li Dawei's skills are much more flexible than before, and his endurance is also much stronger, but chasing wild animals is still not enough, every time it is the 'big tiger' who throws it next to his feet like a prey in his mouth, and when he turns around, his tail sweeps Li Dawei, and he hates iron and steel. Li Dawei went to pull its tail, and then it was a chase that jumped up and down.

Finally one day he pulled back a game, a long goat-like animal, anyway, Li Dawei thought it was a sheep and was chased by him. This stupid sheep panicked and fell into the quagmire that Li Dawei once fell into, catching turtles in the urn.

Without using his IQ, Li Dawei had a sense of accomplishment, carried it back and threw it to the 'big tiger', snorted lightly, put his hands on his back, and tilted his head up forty-five degrees, with a proud face.

The 'big tiger' was very hurt, and a tiger jumped and pounced, and this time Li Dawei fled, and a few dodges went outside the cave. The sea is wide and the fish jumps, the sky is high and the birds fly, the forest is always bigger than the cave, and the interest of returning to the jungle 'big tiger' is high.

Li Dawei bends left and right, but the big tiger chooses the most direct route, isn't this cheating? Between brothers, these details are not important, and catching up is to wash your face with saliva.

The two brothers chased birds and animals all over the mountain, and there was no place to put the meat in the house. Since there was 'Luminous Sand', Li Dawei has caused a lot of disasters to He Shou Wu, steamed, roasted, stewed, and even braised offal.

The effect of He Shou's black hair is really good, the eyebrows have grown out early, the hair is also old, black and beautiful, the key is to look down, there are also blackheads, every morning is a pillar of optimus to wake up himself, this can be proud, there has been no such feeling for many years.

Since the 'Erlong' came, the 'big tiger' has a sense of crisis, he used to sleep alone on the platform on the top of the cave, and now he has to squeeze together, since one night Li Dawei had a very 'comfortable' dream, and took a bath early in the morning, the 'big tiger' looked at him strangely.

The autumn was crisp, and the two brothers went to patrol the mountains to declare their sovereignty and show their obscenity. It turned out that the place where the giant python was fought was left with only a complete dry skeleton. Li Dawei curiously entered the cave where he found the 'Erlong', and the eggs inside had all turned into dead eggs, and he wondered if they had been smoked at that time.

After a day's journey from here to the south, the 'Big Tiger' refused to go any further, and seemed very resistant, and his behavior became irritable, and his behavior was very abnormal, but Li Dawei paid great attention to his brother's feelings.

"Brother Big Tiger, if you need help, say it as soon as possible, viagra will be angry for you", comforted the 'Big Tiger', and the two brothers changed directions. The road is not very good, but Li Dawei drew the map with charcoal. It's very rough compared to modern maps, but the scale, the contour lines, and the north-south direction are all there.

Three days later, in order to chase a wild roe deer, the two brothers ran violently. As a result, the roe deer disappeared in a dense forest. And Li Dawei was very embarrassed to find that he seemed to be lost. smoothed his 'hair' and said to the 'big tiger': "Brother, do you still know which direction our family is?" ”

The 'big tiger' scoffed at this, looked up and sniffed the scent, and then walked resolutely in one direction, and behind a pile of bushes was a small canyon, on both sides of which were rocky, overgrown with weeds and low bushes, and the wild roe deer had disappeared along the road.

At the same time, they all missed, and the two brothers were a little embarrassed, and they couldn't hold their faces. It's all here, keep looking inside. The canyon is generally full of insects and birds, small animals come and go, but this one feels eerie, a little too quiet, Li Dawei is nervous, is there a fierce beast entrenched here to clear the scene.

The last time I killed the giant python, it was completely by luck, and I guess I can't beat the two brothers like this again. 'Big Tiger' didn't seem to have this feeling, the more he walked in, the more Li Dawei muttered in his heart, looked carefully left and right, and found that these stones were a little awkward, what he had seen before was black, gray, and white, but here it was green and rusty.

Pick up a piece and take a closer look, the stone is dark green, with stripes of color, this is jade? Li Dawei suddenly became excited, this thing was expensive in his previous life, and his salary was enough to buy a nail cover.

I took my nails and pulled it, pondered it a little, and threw the stone on my hand in a dejected manner, which should be malachite, but also a kind of gemstone, also called sapphire jadeite, or blue chalcedony, but the hardness, the value is worse than jadeite, the price is much cheaper, I didn't have the money to buy jadeite, so I bought this thing.

Regretting that it was only three seconds, he pounced again, picked up the stone, picked up several more pieces nearby, held it in his arms and looked up to the sky and smiled, which startled the 'big tiger' and roared with it.

Li Dawei mentally scolded himself 'really stupid', his thinking was restricted, just thinking about whether it was worth it as an ornament, this is malachite, the main ingredient is basic copper carbonate, which is the associated ore of copper ore, there is a copper mine here, and this thing itself contains copper, it has always been the equipment of the 'Stone Age', and I forgot to pursue it when I was used to it.

Copper is valuable in any era, it is a currency in ancient times, and it is also a precious metal in modern times, but Li Dawei thinks that he can finally make great strides from the 'Stone Age' to the 'Bronze Age'.

Staying out for a long time, collecting some of the most pleasing to the eye, that is, the greenest stones, throwing away some small game meat caught all the way, filling the frame, dead and sinking, provoked the 'big tiger' boss is unwilling, promising that it can eat more honey after going back before reluctant to leave, no way, there is a third child at home.

Back to his 'lair', it's been a week since he left home, and 'Erlong' has been very aggrieved in the jar, and Li Dawei has been greasy with him since he took it out.

"If you get iron, you will turn it into copper" This is a nonsense, if there is iron, what kind of copper do you have to work hard to get. Copper obtained from malachite was mentioned in junior high school textbooks, and it is really not difficult, in a word, burn.

The main component of malachite is basic copper carbonate, which is decomposed by heat to produce copper oxide, carbon dioxide and water, and copper oxide can be reduced to copper by reacting with carbon under high temperature conditions.

The things that took so much effort to carry back, except for a piece that was particularly good-looking and were left behind, all the others were used, and the copper water was not much. Slowly poured into a mold made of clay, only a copper knife and a three-edged thorn were obtained. The former is used to improve life, and the latter is used to save life.

The three-edged thorn is sharp and thick, Li Dawei made a bloodletting groove on it psychologically, and went out to find a big head, it was really such a small opening, and he bled the wild sheep to death, Li Dawei said that he was very satisfied, with this 'artifact' in his hand, and then he met a giant python, as long as he had the opportunity to take it out, the chance to win was still very big.

This copper is not enough, there are too many places to use, of course iron is more perfect. Determined to leave enough camphor trees, the cave was filled with a pungent fragrance, sealed the entrance of the cave, and dragged the family straight to the copper mine canyon.

It is said to be a small canyon, but it actually stretches for a long time, and it doesn't end after a day's walk. Now I finally feel the hardships of the working people, this is still the situation of picking up ore casually, the temperature of the wood is not high enough, charcoal must be used, charcoal is also a necessary thing for the reduction of copper oxide.

It took half a month just to dig a pit and burn charcoal, and Li Dawei felt that the whole person had turned black. It is also necessary to build a 'stove' and make molds, and the amount of demand is too much, and the workload will not only increase exponentially. Flying claws, arrows, spears... Even a pickaxe was made, and when the days were cold after all these busy days, winter finally arrived.

It's time to go home, 'Xiao San' wandered around, didn't expect to find a vein in a crack, yellow, Li Dawei will not narcissistically think that he has found the legendary dog's head gold, this main mine should be sulfur and copper.

I don't want to make copper anymore, but there is sulfur, and I have to work hard for that obsession in my heart. There was no coal, so we had to use charcoal, which was layered with ore, and the outside was tamped with earth and a furnace was built. There is a bulge in the middle of the stove top, and a round hole is vacated, on which is placed an inverted bowl, but the edge of the bowl is rolled inward with a groove, and a small hole is cut next to it. The power of the individual is too small, and I have been busy for half a month.

The element of sulfur is oxidized to elemental sulfur, which is turned into gas when heated, condensed into a liquid at the inverted bowl, flows into the groove along the inner wall, and flows into the prepared jar along the pipe through the small eye, and finally condenses into solid sulfur. It's just not easy.

When I passed by the fruit forest on the way home, I remembered that the fruit wine I had made was a success? When the seal was opened, a sweet aroma mixed with the aroma of wine came to the nose, and the 'big tiger' began to drip down.

Take a broken bowl and scoop some out, although there are some broken pulp, slightly mixed, but the color is golden, the appearance is still good, taste a bite, the taste is very good, the alcohol content is not high, six or seven degrees.

Served a big bowl to the big tiger, it was actually a good drinker, and it was still noisy to drink, because it became cold, the drowsy 'Erlong' also got up, and its physique, it didn't take long for the whole body to straighten, and the amount of wine was not good.

It's rare to relax, Li Dawei and the two brothers 'Big Tiger', you have a bowl and I have a bowl, fruit wine is also wine, this cellar is higher than the degree of beer, because the sweetness can't be felt at the time, but the stamina is enough.

When the cellar mouth was resealed and walked back, the two brothers did not walk in a straight line.
