Stone Era: Restarting Civilization

The Sagara Oilfield is in the Land of the Rising Sun, and it doesn't make any sense to continue to stay on this resource-poor island.

After the repairs were completed, Pan Changgong immediately ordered everyone to prepare to leave and return to the Land of the Rising Sun. During the repair period, he used the wood on the island to make several small boats.

Amaryllis, the villagers of Baiye Village headed by Wuyu, Shrike, and Dalan will also leave with him. After all, they have surrendered, and he is his own. If they continue to stay on the island, they will also leave. It will not end well.

Without petrochemical weapons, the villagers of Ishigami Village, an angry island, will probably retaliate against them.

In order to avoid such a tragedy, Pan Changgong took them away. After all, they can be regarded as a bunch of cheap labor.

However, what surprised Pan Changgong was.

The people in Ishigami Village on the sea island knew that they were about to leave, and the people headed by the village head immediately approached him, hoping to take them to leave the island together.

They have been talking to everyone in the Ishigami village headed by Obsidian these days. Knowing the vastness of the outside world, I understand the smallness of the small island where I am.

Feeling that there is no future for staying on this small island, in order to develop and expand their own tribe, all the villagers in Ishigami Village on the island hope to leave with Pan Changgong.

Pan Changgong looked at their eager eyes and nodded in agreement.

A week later, they finally arrived at 98 Land of the Rising Sun.

After another two days of walking, I finally arrived at Gangjing Village.

The main reason is that there are many old and weak women and children in Ishigami Village and Baiya Village on the island, and they slow down the marching speed.

The villagers of Ishigami Village and Baiya Village on the sea island were shocked when they saw the well-developed Okadazu Village, and they were very curious about everything.

Pan Changgong has had two immigration experiences, and this time brought more people. There are hundreds of people in the two villages.

Pan Changgong had found several places suitable for settlement and farming before, selected the two places closest to him, and arranged for people to build houses and cultivate farmland.

Now to do these things, you don’t need to do it yourself. After several demonstrations by yourself, as long as you are not a fool, you will understand.

The names of Ishigami Village on the island and Ishigami Village are exactly the same. In order to avoid some misunderstandings in the verbal distinction, Pan Changgong changed the name of Ishigami Village on the island to "Pan Shen Village".

Well, Pan Changgong admits that this is a very rustic name, and it has a strong sense of utilitarianism.

But the Ishigami village on the island is smart, and they don’t feel that there is anything wrong with it. On the contrary, they think that this name has an obvious leader’s atmosphere compared with other villages. They think it is a kind of honor that the leader of Pan Changgong cares for them. .

After everything was arranged properly, Pan Changtai plunged into his laboratory.

If you want to quickly search for the Sagara oil field, it is most convenient to use satellite photos to shoot from high altitude to the ground when the world order is still normal.

Being condescending, you can see many scenes clearly at one time and have a panoramic view.

Now the satellite must be gone, so a camera is made to take pictures manually from a high altitude.

How to get into the sky.

Naturally, hot air balloons were used.

The principle of photography is also very simple, requiring some knowledge of chemistry, and the main chemical element involved in photography is silver.

Silver will turn black after being exposed to sunlight, and this principle can be used to take black and white photos.

The production method of the camera is actually not very complicated, but the camera produced by the current technical means is very primitive, so there is no need to pursue any performance.

The first step in making a camera is to make a mirror.

Speaking of which, Pan Changgong has not made a mirror so far, mainly because he finds it troublesome and he is delayed by many things.

If you want to look in the mirror, you should look in the bronze mirror. For yourself, copper is also a precious resource. Bronze mirrors have not been popularized in all villages, only a few people,

Most people look at themselves directly from their reflection on the water.

If there is no mirror when the social order is still normal, it is definitely an unbearable nightmare for girls.

But now there are no cosmetics in this situation, so I am forced to use mirrors to make up.

The production of the mirror is very simple, and the materials include sodium hydroxide, silver, and ammonia (urine) [Pan Changgong happens to have all these materials in his hand.

Mix them all together, and then put a piece of transparent glass into the smelly mixture, and after a dozen seconds, clamp the mirror out, and the mirror is ready, which can clearly show people reflected.

Then dry the surface of the mirror, and paste paper or carbon on the bottom surface, so that the silver plating can be prevented from falling off.

However, after a while, Pan Changgong realized that the mirror (ajfc) produced in this way had a very bad smell and needed to be exposed to the sun for several hours to get rid of the smell.

To avoid this problem, add a little glucose to the sodium hydroxide, silver, and ammonia mixture.

Glucose is extracted from glucose stems. Grapes can grow well as long as there is sufficient sunlight, and wild grapes are everywhere around them.

Later, Pan Changgong asked Grandpa Fossil to make a cubic wooden frame. After seeing the design, Grandpa Fossil didn’t understand what the wooden frame was for. The shape was so strange.

There is a small rectangular hole in the center of one side, and a small circular opening on the upper and lower sides, which can be separated from the middle.

But if it's someone from modern civilized society, it's instantly recognizable as a crude, old-fashioned video camera.

After the box cube wooden box is finished, open it, put the finished mirror into the wooden box, and the wooden box has the function of darkroom.

Pour salt water into one of the small circular holes, and then pour it out of the other circular small hole.

In this way, the filling of the film (mirror) is completed.

Such a camera is very primitive, and only one film can be placed in it at a time, that is, a mirror.

After shooting, heat the mercury to extract the shaping liquid from the sulfur, pour them all into the wooden box, and the shaped picture on the mirror inside will be displayed.

It can be said that the efficiency is very low, and the photos taken are all black and white, but it is better than nothing.

After Pan Changgong invented the camera, he gathered people together. He wanted to show the camera to everyone, not for the purpose of showing off, but just to take a photo for everyone as a souvenir.

Everyone who is also from the modern era is very happy about this and looks forward to it.

The villagers of Ishigami Village, Panshen Village, and Baiye Village looked confused and completely confused.

It was when they saw their images reflected in the mirror that they all acted very frightened.

"What's going on here? How did we get so small inside the glass?"

"Is that our soul? Has our soul been taken?"

Because they had never seen a camera before, and they didn't understand the camera, the more primitive people thought about it, the more they panicked, which almost caused a riot.

Under the comfort of Asagiri Gen's explanation, these primitive people accepted the saying that the camera can draw pictures in an instant.

Beixinan was originally a reporter, and the camera was something she used to touch every day. After waking up from this primitive society, she has always missed the scene of taking a camera to shoot everywhere.

Knowing that Pan Changgong wanted to use the camera in the early Ming Dynasty to take pictures in the air to find oil fields, he took the initiative to undertake this task.

Pan Changgong also agreed, probably no one is more suitable to use the camera than him.

The three people, headed by North, East, South and South, took a hot air balloon and took high-altitude shooting in the Okashiro area.

This kind of shooting activity lasted for half a month, and many glass photos were developed every day. After careful screening by Pan Changgong, he finally found a touch of black exposed on the ground in one of the photos.

The Sagara oil field is a surface oil field, and plants cannot grow in the oil field. If you look down from a high altitude, you can see it at a glance.

Pan Changgong personally took people there, according to the instructions on the photo, after walking for two hours on foot, he finally found it.
