Stone Era: Restarting Civilization

Pan Changgong didn't know what happened on the island.

After spending several days in a hot air balloon, I returned directly to Okashira Village.

Those in the Ishigami Senkuu camp have all moved over here.

From the current point of view, everything is quite harmonious, and there are no twists and turns.

Pan Changgong didn't know that the people who were resurrected by Ishigami Senkuu followed the large army to Gangjing Village, and they were all shocked. Is this a village managed by an absolute ruler? It is so prosperous, even if Pan Changgong really wants to It doesn't matter to them when they are emperors, as long as their lives are good - that's fine.

After Pan Changgong came back, he immediately gathered the villagers of the two villages and told everyone what he found during his trip.

Human beings still live on a small sea island near the Land of the Rising Sun.

And also has the technology that can petrify others, Ishigami Senkuu and his party have already encountered poisonous hands.

The shock of this news is self-evident.

Pan Changgong: "Those guys on the island probably know the truth about petrification, and they are in the petrification disaster thousands of years ago, they have vested interests, so all human beings are petrified, but they are not petrified, although it is not clear why they are in On the island, but judging from their direct actions to petrify Ishigami Senkuu and others, they are absolutely unfriendly to outsiders. Because of the petrification disaster more than 3,000 years ago, human civilization was burnt. Are you willing? Don’t you want to know the truth? ?"

"We are not reconciled, we must know the truth" everyone at the scene shouted loudly, each face filled with

"That's right, although the opponent has the ability to petrify, but their ability is limited, otherwise, I would not be able to return safely, so I decided to set up a crusade team to control the small island, and will be behind the scenes on the island The black hand was captured, let him tell us the truth, so as to prevent human beings from repeating the same mistakes, do you agree?"

"good"

Pan Changgong looked at the righteous indignation of the crowd, the corners of his mouth slightly raised, and he had achieved his goal.

Pan Changgong really wants to know the truth about petrification. Although the petrification disaster has not happened once in the 3,000 years of his life, it has always been lingering in his head like a nightmare.

He was lucky enough to break the petrochemical once because of nuclear radiation, but if the petrochemical reappears one day, what should he do?

Although he has already researched the Miracle Water to crack petrification, it has to be made by outsiders. And just pour it on yourself

You must know that in the catastrophe that petrified all mankind, it seems that no one survived except the mastermind behind the scenes and the astronauts in outer space.

Pan Changgong felt that he had another good luck, so this expedition was imperative.

For this expedition, Pan Changgong is very cautious. In order to ensure the success rate, he must send as many people as possible and equip enough weapons.

Pan Changgong originally had a team of more than 1,000 people, but more than 400 people could be taken out. The remaining people need to participate in production activities to ensure the production of food.

Because of the addition of Ishigami Senkuu's resurrected people, Pan Changgong pulled out all the men from these people, and selected a few from Okashizumura to form an expedition team of 500 people.

The next step is to prepare items for expeditions. Ships are essential, but only small boats can be built. Building large ships requires a lot of technology.

In addition, it is necessary to build several manned hot air balloons, the number does not need to be large, and the operation of hot air balloons also has a certain technical content.

Pan Changgong once studied books on aerodynamics and the structure of hot air balloons, and there happened to be a hot air balloon ride tourist attraction in Gangjing City.

But for ordinary people, the control of hot air balloons is much more difficult than rowing boats. I need to act as soon as possible, and I don’t have time to train them to control hot air balloons. Therefore, the main means of transportation for expeditions is still ships.

The craftsmen headed by Fossil Grandpa and Chromium are busy

With the means of transportation, the next step is weapons. There are enough iron weapons, crossbows and bamboo helmets in front of the warehouse.

Gunpowder is of course indispensable, but because there was no need before, not much was actually produced. The 400-person team that was brought out to fight against the traitors had only one gunpowder bag per person.

Ishigami Senkuu's defection caused his minions to send people to collect a lot of sulfur, which can now be used directly, all of which are used to make gunpowder.

In addition to gunpowder, Pan Changgong also directed himself to make another weapon.

That is tear gas, and its chemical name is chloracetone.

The production method is very simple, because the raw material is wood, any wood can be used.

Build an airtight metal container, then throw the wood into the metal container.

0…………seeking flowers.

Then use the fire to bake the metal container, and the wood will not burn because it is not in direct contact with the fire.

However, during high-temperature baking, chemical reactions will also occur, and blue smoke will rise.

A small opening must be opened on the metal container, and a side pipe is installed, and the side pipe is connected to the metal container and the sealed glass container.

So that the smoke from the wood baked in the metal container can pass through the side pipe and enter the glass container.

These smokes also contain water, because fresh wood itself contains water.

Therefore, if the cut wood is used as firewood, it cannot be burned directly. It is best to dry it in the sun to evaporate the water in it.

The water vapor of wood smoke entering the sealed transparent glass will gradually condense and form water droplets. Its chemical name is wood acetic acid, which is mainly composed of acetic acid, acetone and methanol

...0

By mixing wood acetic acid and calcium carbonate (that is, ground shells) and boiling, you can get a mixture of oleodosin and disinfectant odorant, which can produce a tear-inducing effect when put in.

In addition, the paper shield is also a must-have item for this expedition. The principle of the paper shield is actually very simple, but Pan Changgong didn't think of it at all before. He got the inspiration after seeing the shields in the hands of the guys who were resurrected by Ishigami Senkuu.

From this point of view, Ishigami Senkuu is indeed a talent, but it's a pity that he didn't deal with him.

In terms of weapons, even if the preparations are complete, if the time is not limited, Pan Changgong would like to make an arquebus.

Food and the charcoal needed for burning hot air balloons, as necessary resources, are also indispensable.

In addition, if a war is launched, there will definitely be casualties, and Pan Changgong does not want his own people to suffer large-scale casualties.

You must know that in the poor medical conditions now, if you suffer a little trauma, you may die of infection.

Fortunately, I also know some medicine.

Pan Changgong ordered some people to collect a large amount of willow bark, wash it and dry it in the sun.

At the beginning, everyone didn't know why, but when all the people who went out to fight were given a pack of willow bark, and learned from Pan Changgong that willow bark is used to relieve pain, if the injury is unbearable, chew willow Skin

This made everyone feel incredible, and even felt that Hiroto was ignored.

Chewing willow bark can actually relieve pain. In Chinese herbal medicine, willow bark is also one of the traditional Chinese medicines for controlling fever. .
