After Yanhu and Cangshi came back, they were surprised to see the seven long-nosed elephants who had gotten along very well with the tribesmen.
The long-nosed elephant is large and powerful.
Taking them to quarry stones, the transportation of stones can be solved a lot, and the remaining stones can be moved back by the new tribesmen.
"Wu, it's much easier for us to transport stones now. With these long-nosed elephants and the net bags made by you, Wu, we can transport stones much more easily!" Yan Hu said with a smile.
Cangshi also nodded and said: "Yes, Wu, the network you asked the Ministry of Life to compile is much easier to use than the previous one. The previous one required two people to hold it together. The newly compiled network can be held by one person, and it can be dropped." There aren’t too many stones left.”
Yang Cheng smiled and asked: "How was the stone mining? How much was it?"
Yanhu and Cangshi looked at each other and hesitated to explain clearly.
Seeing the two of them like this, Yang Cheng slapped his forehead and forgot that primitive people didn't have a big concept of quantity.
Okay, when you have some free time, determine some of the tribe's weights and measures.
Otherwise, when it comes to the specific number of objects, these primitive people cannot explain clearly, which will delay things.
Yang Cheng said: "Forget it, you don't need to say anything, just take me to see it."
Hearing this, the two breathed a sigh of relief.
Then he led Yang Cheng to the place where the quarrying team unloaded stones.
The totem warriors and the exiles in the quarrying team had just unloaded the stones from their backs and were drinking water from bamboo tubes.
Seeing Yang Cheng coming with Yanhu and Cangshi, they all hurriedly stood up and saluted: "Witch."
Yang Cheng waved his hand and asked them to continue resting.
Then he looked at the stones arranged like a hill, turned around and asked, "Yanhu, where is the stone you collected today?"
"A bunch of them over here."
Yanhu drew something on the hill-like pile of rocks.
Yang Cheng looked along the area drawn by his finger. The pile of stones Yan Hu painted had more stones than yesterday, but not much more.
Yang Cheng estimated in his mind that the stones in front of him were about 200 cubic meters. In other words, after two days, the stones mined by Yanhu and the others averaged 100 cubic meters a day.
The space of a bedroom is about 40 cubic meters, and if it is a larger bedroom, the space is about 100 cubic meters.
This is a unit of space, and the construction materials may only require about twenty or thirty cubic meters.
Therefore, the stone materials that Yanhu and the others transport back every day can be used to build three or four bedrooms.
However, considering that there are nearly 60 people in the new tribe, even if three people sleep in one bedroom, it will still require about 20 houses. It will take four or five days to move the stones from the quarry back to the tribe.
The carrying efficiency of sixty people is also very high for the ancient feudal society, not to mention the primitive society on earth.
Yang Cheng felt it was not enough!
The season for building houses has already entered winter, and it has snowed today. Maybe the temperature will drop even more in the next few days.
And the new tribe members are still living in tents, and they do not have the power of totems to protect themselves. If this continues, frostbite is common, and death is not impossible!
We must quickly get the new tribesmen to move out of their tents and into new houses!
"We have to speed up!"
Yang Cheng turned his head, looked at Yanhu and Cangshi, and said firmly: "Yanhu, Cangshi, please speed up the transportation and move more rocks out. We have to build a house later, which will also take a lot of time. "
Yanhu and Cangshi nodded: "Don't worry, Wu, we now have a long-nosed elephant who can carry a lot of stones at one time, and the speed will definitely be improved."
It can be seen that the two of them are full of confidence.
Yang Cheng frowned and said: "The proboscis elephant can speed up our transportation, but it takes time to mine stones, which the proboscis elephant cannot do."
The Qingque tribe's current method of mining stone is expansion with heat and contraction with cold.
This method can explode a large stone into many small stones through expansion. Compared with the original stupid method of just smashing and prying with force, the efficiency has been greatly improved.
However, there is a problem that must be ignored.
This method takes time. You must first heat the stone and then pour water on it.
If the temperature is higher, the stone is inherently warmer and can heat up quickly.
But this winter, it snows, and it takes a very long time to heat the stones.
The last time Yang Cheng performed thermal expansion and contraction, he burned it for a long time and added firewood several times before he felt the temperature was right.
When Yanhu and Cangshi heard this, the excited smiles on their faces disappeared.
I am also troubled by this problem.
Yes, the transportation problem has been solved, but the efficiency of mining stone is still there.
It would be fine if there is no rush to build a house, just mine slowly.
But it's snowing now, the temperature has dropped, and the Qingque tribe's cave is so big that it can't accommodate all the tribesmen.
Therefore, the house must be built quickly.
Yanhu and Cangshi thought about it for a long time, but neither of them came up with it.
But soon, the two looked at each other. Why were they thinking about this problem?
Can they figure it out with just two of their heads?
Yanhu and Cangshi quickly set their sights on Yang Cheng, looking at him with unblinking eyes and full of expectation.
As a shaman from the Qingque Tribe, Yang Cheng must have a smart mind, and he must be able to think of a solution to this problem.
But this time, Yang Cheng disappointed them.
Yang Cheng rubbed his chin and thought for a long time but still couldn't come up with a good solution.
If you want to increase mining efficiency again, the easiest way is to improve mining methods. What is a better method than thermal expansion and contraction?
Blow it up with gunpowder!
Mononitrile, disulfide and charcoal!
A must-know formula for time-travelers!
After Yang Cheng traveled through time and became a shaman, he knew that there were ferocious beasts in this world. He immediately thought of using gunpowder to blow up these ferocious beasts.
However, charcoal is easy to find. Burning wood becomes charcoal. Saltpeter is also easy to find. Its main component is potassium nitrate. Plant ash and saltpeter can be used as raw materials to make potassium nitrate.
Needless to say, plant ash is the plant ash after the herbs are burned.
Saltpeter is generally found in toilets, pig and cattle pens, and hard ground that is not easily impacted by rain.
But what about sulfur?
Where to find sulfur?
