Chapter 219
Among the trees, Rubber Tree and Pine are the two most useful wood materials for Tang Zheng at this stage.
One type can be collected to extract rubber, while the other can be extracted from resin, which is the raw material for plastic.
Ming branch, which is moving towards the semi-industrial era, happens to be a branch of plastics. After the pine trees grow up, they can be made by hand chains.
Be prepared for a rainy day.
As for the tree species, Tang Zheng bought it from the players on the forum yesterday, and the price is not expensive.
After all, at this stage, with explicit restrictions, many players want these things to be of little use.
"Okay! The task must be completed!" Lan Lan has a small chest, serious and focused.
Receiving two bags of seeds, Tang Zheng gave her an iron shovel, which is as tall as Lanlan.
As for Moffett, there is no need to give it tools. For its size, pulling roots is like pulling carrots, and the palm of the hand will come down.
"Master, goodbye, I'll go, I can make pocket money." Looking at the back of the little girl who was walking away with a shovel excitedly, Tang Zheng couldn't help but think of his childhood.
I don’t need mineral water bottles or paper or cardboard at home. Every time I save a pile and take it to the garbage collection station, I sell it for a few dollars and buy a bottle of iced Coke.
In the scorching summer, listening to the croaking sound developed by the screwing of the bottle cap, I took a sip of cold and refreshing Coke.
A satisfying admiration is a happy memory of childhood.
"Speaking of which, I haven't drank carbonated drinks for almost a month. I don't know what Earth has become now." Tang Zheng sighed softly.
Immediately, he shook his head and gave a wry smile.
Perhaps Earth, without humans, is its healthiest appearance.
The 28-day collective transfer of all mankind, most of the towns on Earth, and the streets and alleys are probably full of wild animals.
All kinds of damaged foods will also begin to produce mold.
If the time is longer, it is not unusual for a tree to grow at home.
Soon, Tang Zheng recovered his thoughts drifting far away.
Let's live through the current situation. Whether you can return to Earth in this life is two different things.
As the evening approaches, the first high-temperature furnace was born.
Excellent attribute, a structure composed of steel and flint.
The maximum internal temperature can reach 5,000 degrees Celsius, which is almost like a little sun.
Know that the surface temperature of the sun is only 6000 degrees Celsius.
Under this high temperature, almost all solid surface rocks can be melted.
Take out 10 parts of Lishi and throw them into the high-temperature furnace, and add wood.
The high-temperature furnace is producing refined Lishi, and the remaining time is 5:59:59
With the progress of the times, the production time of these materials is getting longer and longer.
But the same goes for other players.
Tang Zheng estimates that if Ming develops to the later stage, when he can build airplanes and ships, it may not take several months to build an airplane.
But, even if it takes a few months, it has surpassed thousands of years of human development, and the speed is still as fast as flying in the air on a rocket.
From the small window of the high-temperature furnace, Tang Zheng can see the blue flames burning inside.
The blue flame means that the internal temperature is as high as five-six thousand degrees Celsius.
In ancient times, when humans did not have professional high-temperature test equipment, experienced blacksmiths could judge the temperature in the flame only through naked eye.
The principle is actually easy to explain in modern times.
When the flame temperature is lower, it will emit a longer-wavelength luster, which is a warm red-orange-yellow color.
The higher the flame temperature, the shorter the wavelength of light will be emitted, which is the blue purple light.
When the temperature is close to tens of thousands of degrees Celsius, the color of the flame will disappear, forming an ultraviolet luster that cannot be captured by the naked eye of humans.
Of course, it is limited to the light that has been refracted in the atmosphere.
Only standing next to the furnace for a while, Tang Zheng was already hot and sweaty.
Fortunately, the item produced by the synthesis platform has some special hidden attributes.
It can isolate part of the high temperature from flowing to the outside world.
"Fortunately, it was placed a bit far from the door of the house this time. This area is a little bit empty and will not cause the trees to spontaneously burn." Tang Zheng looked around all around. This is the concentrated invasion point of the previous monster frenzy. , The fierce battle caused all the trees in this area to be pulled up by the roots, leaving only a bare land.
However, in terms of scope, it can only hold about ten high-temperature furnaces.
No matter how much it is, I am afraid it will burn the trees.
"Synthesizer can't be idle and continue to do things." Tang Zheng thought for a while.
After making a choice between the second high-temperature furnace and steel tools.
The priority authoring tool is selected.
Throw the steel into Synthetic Taichung. The production time is 12 hours, and it will not be completed until I wake up tomorrow.
On the 30th day of survival.
Humans have been transferred to this alien world for a month.
And Ming's development, from bare hands to the present, almost everyone has entered the Bronze Age.
Tang Zheng has seen the gradual progress towards Rong in photos or videos uploaded by some players on the forum.
In the major tribes, neat stone houses have been built up one after another, arranged in a straight line, looking like villages.
In front of the house, a straight stone pavement forms the street from east to west.
On the stone pavement side, there have been successive wooden carts or horse-drawn carts in use.
There are many more stalls, including breakfast, clothing, daily use, and entertainment.
The planting and animal husbandry industries have developed, and other diversified elements are also moving towards a prosperous progress.
Except that there is no shadow of modern times, other aspects have become more perfect.
