After returning to the central tribe, Ye Qiong went straight to his small experimental base in the central tribe.
Tang Ying has been taking care of this laboratory, mainly recording the data of chronic experiments, as well as the vegetation grown in the laboratory.
After entering the test laboratory, the temperature immediately rose. There were four wooden barrel grease lamps in the room, which were burning all day long, ensuring that the indoor temperature was always around 20 degrees.
At this temperature, vegetation can maintain its growth state under the condition of a light source.
Looking at the clean and warm laboratory, Ye Qiong smiled with satisfaction after entering, then took off his animal skin coat and hung it on the iron nail behind the wooden door.
Ye Qiong first walked to some areas where vegetation was planted and inspected it. Generally speaking, they were growing well. These vegetations were all small plants that could bloom and bear fruit. Among them were the beams brought back by the caravan last winter.
What surprised Ye Qiong was that there were a few pellets that looked like mini corn cobs on the beam poles. The yield seemed to be pretty good.
This means that as long as the leaf dome can solve the problem of indoor temperature in winter, it is completely possible to grow vegetation and crops indoors.
It won't be possible to build a plastic greenhouse for a while, but maintaining a constant indoor temperature and having a light source is not that difficult for today's tribes.
Whether it’s coal or barrel grease lamps, the tribe’s current reserves are staggering!
These two things alone are enough to maintain a constant temperature in the tribe's small house. If some areas can be set aside on each floor of the pyramid living area, a lot of food problems can be solved in the coming winter.
At present, the tribe's food source in winter is still meat, with almost no whole grains, and the reserves of dried fruits and vegetables are also limited.
Although there is no shortage of food for the tribe now, without these whole grains, fruits and vegetables, over time, it will still cause vitamin deficiency, and it is possible to suffer from scurvy and other diseases.
Tribes have moved on from the era of eating raw meat to obtain vitamins. If the problem of fruits and vegetables cannot be solved, the only way to obtain vitamins in winter is to eat raw meat directly.
Whether it is the meat of Warcraft or the meat of ordinary small beasts, it contains a small amount of vitamins. If it is eaten raw, the body can absorb some of it, but when it is cooked, it will be gone.
Meat, especially the livers of some monsters and small animals, still contain a lot of vitamins and various trace elements necessary for the human body, but eating them raw is a helpless move. While obtaining vitamins, it also increases Infections by parasites and various bacteria and viruses, things that cannot be seen with the naked eye, are often much more terrifying than beasts and crazy crowds.
Tribes destroyed by beasts and madmen at least have traces of how they died, while tribes eroded by bacteria and viruses will disappear inexplicably.
Like the ancestors of the Na Ning tribe at the base of the waterfall...
After pouring some water on the vegetation on the wooden frame, Ye Qiong stretched out his right hand and gently touched the leaves and fruits of the vegetation. These things are the future rations of the tribe and have very high research value.
After putting down the kettle, Ye Qiong turned around and came to the wooden table, lighting the slightly larger grease lamp on the wooden table.
The area around the wooden table suddenly became brighter, and he took out the animal skin bag from his waist.
"Kuang kuang... kuang kuang kuang..."
In the animal skin bag, Ye Qiong poured all the amber brought back from the coal mine base onto the wooden table.
After moving the grease lamp in front of him, Ye Qiong began to look at the grease lamp and carefully observed the amber.
The colors of amber are also different. Although the overall appearance is yellow, if you look closely, the color depth is different. The heavier ones appear darker and more yellowish brown.
As for the contents inside, I can't see clearly yet. I can only see some black shadows, and the transparency is not very high.
If you want to find out what is wrapped inside, you have to smash the amber.
But in that case, it seems a bit wasteful...
There are a total of six ambers placed on Ye Qiong's table. Ye Qiong picked one with a medium transparency and picked it up. He squeezed it hard and found that it was still quite hard, so he took the bone crystal dagger directly from his waist. Pulled out.
Holding the bone crystal dagger, Ye Qiong made several gestures at the amber. He was still hesitating whether to cut it open and take a look.
The thing wrapped inside is like opening a blind box, and it is also like Schrödinger's cat. Only after it is cut open can the result be known. Otherwise, it will always be in a superposition state.
After squeezing hard for a few more times, Ye Qiong no longer hesitated and placed the amber on the wooden table. Then he stretched out two fingers of his left hand to fix it, and pressed down the bone crystal dagger with his right hand, half smashing and half cutting it. , directly cut the amber on the wooden table into two pieces.
The bone crystal dagger is a weapon that can cut through iron like clay, so when dealing with this kind of amber fossil, it is naturally very easy to cut it open.
Ye Qiong subconsciously took the two pieces of cut amber farther away, and after confirming that the black shadow inside was already in a semi-petrified state, he took it over.
There are some things that must be guarded against, such as ancient viruses. Those things are terrifying, even more terrifying than lord-level monsters...
Ye Qiong continued to look at the light of the grease lamp and found that the thing wrapped inside seemed to be a small leaf based on the texture.
A... small leaf that was hundreds or even tens of millions of years ago was miraculously preserved and presented in front of Ye Qiong.
This tree may have become extinct long ago, but this leaf spanned the long river of time and was sealed in amber.
If the level of science and technology at this time is sufficient, it may be possible to extract the genetic sequence from this semi-petrified vision, and it may be possible to resurrect this ancient creature.
Ye Qiong continued to pick up an amber and cut it directly with the bone crystal dagger. This time it was much easier. The cut position was just in the middle of the shadow. After looking at the lines, he found that it was still a kind of vegetation. leaf.
Looking at the four remaining ambers on the wooden table, Ye Qiong wanted to cut out small animals such as mosquitoes, but he was worried that they would be useless after cutting them out, so he suppressed them. His curiosity stopped, and he put away the two pieces of amber that had been cut into four small pieces, placed them in a small box on the wood, and stored the remaining four complete pieces of amber separately.
"Dong dong... dong dong dong..."
Just when Ye Qiong was putting away Amber, there was a knock on the door.
