Stone Era: Restarting Civilization

After staying on the island for two days, Pan Changgong sent people out to search for the relics left by the astronauts more than 3,000 years ago, and finally found them.

It turns out that it is far away in the sky and close in front of you.

The space capsule that used to be used as a storage object was buried under the old tree in Baiye Village.

After more than 3,000 years of erosion, the extremely hard space capsule has long since decayed.

Pan Changgong had people hit it with a hammer a few times, and the surface was covered with cracks

After breaking open the space capsule, it was found that there was only a small box the size of a palm in the huge space capsule.

Pan Changgong took it out and opened it carefully.

There are many small gadgets in the box, such as rings and earrings made of Rare metal, jade pendants, screws, and some things that Pan Changgong still doesn’t know what they are used for.

But there is one thing that Pan Changgong treasured, and that is the Baijin ring.

Baijin is a kind of rare metal, and with my current technical ability, it is impossible to mine and refine it.

As a type of chemical element, Baijin plays a very important role in the current self.

As long as you mix Baijin and sulfuric acid, you can make nitric acid. Just a little Baijin can reflect a lot of nitric acid. A ring-sized Baijin needs enough sulfuric acid. It can be said that nitric acid can be produced without limit, science is so miraculous

The Baijin ring, which is relatively common in modern civilization, is definitely a strategic weapon for the current self.

You must know that the half-life saltpeter in the gypsum mine I discovered is also limited. According to Pan Changgong's speculation, if all of them are mined, they should be able to produce tens of millions of people who can be resurrected. This number seems huge, but the world's population is More than 7 billion is a drop in the bucket.

Although I have no intention of resurrecting all human beings, even if I want to selectively resurrect some people, tens of millions of people are still too few for this world.

The existence of Baijin can be said to have really helped a lot.

Pan Changgong directly put the Baijin ring on his hand. The size of the Baijin ring is too small to fit in his hand. Only the little finger can fit it, but usually the ring is not put on the little finger. The owner of the Baijin ring is very Possibly a woman.

In addition, Pan Changgong also found an envelope at the bottom of the box. The envelope was very well made, and it was obviously a relic before him. On this island, there are no plants and trees that make good paper.

Pan Changgong picked up the envelope and came to the room where the leader of Baiye Village used to be. The petrified leader had already been thrown away, and because of the fog and rain, he was also buried with honor.

After Pan Changgong read all the contents on the envelope, a look of surprise appeared on his face involuntarily.

The letter, originally intended for Ishigami Senkuu, contained only a few words of greeting, mostly related to the petrochemical disaster.

Ishigami Hyakuya and his team once clearly saw a full-scale Green light burst out on the earth from the International Space Station. This light instantly petrified, and all human beings.

And based on calculations and actual observations, Ishigami Hyakuya found that the source of the petrified light came from the southern Asian American state in the eastern hemisphere.

Ishigami Hyakuya originally wanted to control the space landing capsule and go directly to the beautiful Jianzhou in South Asia to investigate, but because there was no ground navigation and guidance from the command center, they landed on an island near the Land of the Rising Sun.

Then he was trapped on this island for the rest of his life.

If they were lucky enough to land on land at that time and use the abundant resources on land, human civilization would not be so backward in 3000 years.

Or they took advantage of the premise that civilization has not been completely swallowed by nature, and Heli found a way to make miracle water. In more than 3,000 years, human civilization may have fully recovered.

It's a pity that there is no if in the world. If the descendants of the astronauts headed by Ishigami Hyakuya really develop and grow, it is hard to say whether they will have their own today.

"Is it Meijian in South Asia~`?" Pan Changgong closed the envelope and muttered to himself.

The beauty of South Asia is far away from the Land of the Rising Sun, and it takes a journey across the Pacific Ocean to reach it.

The Pacific Ocean is the largest ocean region on the planet, covering an area of ​​more than 100 million square kilometers.

If you want to get from the Land of the Rising Sun to South Asia's beautiful city, when the world order is still normal, it will take more than ten days to take an ordinary modern power boat.

If the paddling is done by manpower, it will take several months, and it must be ensured that there will be no bad weather along the way.

Pan Changgong frowned, this is too unrealistic.

I have to make an advanced ship, such as a sailboat. This is the protagonist in the age of great navigation. At that time, the kingdom that discovered a new land relied on sailboats for trade and immigration.

But I don't have the knowledge of sailboat making.

At this time, Pan Changgong thought of the "Seven Seas Dragon Water" that he had spared his life two days ago.

So someone called him over.

Qihai Longshui, as the young leader of the Apex chaebol in the land of the rising sun, is very confident and arrogant. Even in the current situation, he still has an inexplicable sense of superiority in front of outsiders.

However, Qihailongshui dare not show this kind of superiority in front of Pan Changgong.

He had personally witnessed Pan Changgong's thunderous methods, and in the past few days, Qihai Longshui learned from the process of communicating with the people around him that Pan Changgong is a very powerful character, and he has the mindset of a ruler, not the current him Can afford to offend.

"Master Pan, I specially called you here, do you have anything to tell me?" Qihai Longshui said flatteringly.

Pan Changgong "Listen to François, you know how to sail?"

"Yes, Master Pan, I'm very confident in this point." Speaking of sailing, Seven Seas Longshui immediately burst into dazzling light.

"So do you know how to make a large ship?"

"Large ships? Of course no problem, I have personally participated in the design of large ships"

"That's great. To tell you the truth, I need a ship that can reach the beautiful Jianzhou in South Asia from the Land of the Rising Sun. Can you make it?"

"What? Going to the beautiful Jianzhou in South Asia?" Qihai Longshui was shocked when he heard this.

Pan Changgong didn't hide anything, and there was no need to hide it. In order to find out the truth about petrification, Nanya Meili decided to go.

Qihailongshui was shocked again after hearing what Pan Changgong said.

The source of the petrified light turned out to be South Asia Meijian.

Pan Changgong "As the only remaining human beings on this planet, we must find out the secret of the petrified light, otherwise, it will be meaningless for human beings to develop, because the sudden petrification disaster may be reborn at any time." destroy"

Qihai Longshui nodded with a serious expression, agreeing with this concept very much.

"Master Pan, I really want to realize this wish for you, but I have to tell you a reality. I can design large ships. Without modern power, only sailing ships can travel the fastest. However, it is still too difficult to go to the beauty of South Asia. The Pacific Ocean is different from the Western Ocean. The Europa region in the age of sailing can sail across the Western Ocean to a new land. That is because the Western Ocean itself is relatively small. , and the climate is relatively stable. Our Pacific Ocean is not only nearly twice the size of the Western Ocean in terms of area, but also the climate is very unstable. The difficulty of crossing is too high. If you are lucky, it may take half a year to reach the destination. You have to make sure that there is no bad weather at sea in the past half a year, otherwise you will only die."

Pan Changgong: "`||You mean that the success rate of making a large sailboat across the Pacific Ocean is not high"

Qihai Longshui's heart skipped a beat, worried that if he told the truth, he would be punished because it didn't sound good, but he couldn't make fun of everyone and my own life [nods hard.

Fortunately, Pan Changgong did not punish him, sighed and said: "Then there is no other way?"

Qihai Longshui: "There are other ways, but I think there is no way to do it at all. That is to create a modern power system, which is to use an internal combustion engine or a steam engine to propel the ship. In this way, the time can be greatly shortened. Avoid bad weather, even if you encounter bad weather, if you have a strong power source, you can travel quickly to ensure the chance of survival."

"In that case, let's create a power system," Pan Changgong said calmly.

"What?" Qihai Longshui looked at Pan Changgong incredulously, thinking for a moment that he heard it wrong

The historical development of human civilization is the steam engine first, and then the internal combustion engine.

Apparently, a steam engine is easier to make.

However, whether you want to make a steam engine or an internal combustion engine, you need the corresponding fuel, and you must keep up with it.

Charcoal is definitely not acceptable, it must be coal or oil.

In other words, my primary purpose now is to find coal and oil, otherwise, even if the ship is made, it will have no effect.

However (the money is good) coal and oil are non-renewable resources. After hundreds of years of mining in the era of scientific and technological civilization, the coal mines or oil fields that are easy to mine on the surface of the planet have been mined.

Even if there is, it is because it is deep underground.

At present, there is no qualified drainage, ventilation, and anti-collapse technical support here, so there is no way to mine.

For others, this problem may really be a knot, but for myself, it is not impossible

Pan Changgong is also well-read. He once read in a book on oil that the Land of the Rising Sun actually has oil, and several of them are on the surface and are easy to mine.

It's just that the oil production on the land of the Land of the Rising Sun is very scarce, and there is no need to exploit it at all. After all, the investment is so large, and it will not produce enough economic benefits if it goes on.

These oils that are on the surface and have a small output are more than enough for one person and one ship.

Pan Changgong remembered that there was such a surface oil field near Gangjing, and its name was Sagara Oil Field.

But I really don't know where it is, I only know that it is in the Gangjing area.

I didn't go to every corner of the Okada area.

If you search slowly by foot power, it will take a lot of time.

Thinking of this, an idea flashed in Pan Changgong's mind, and a rough plan had already taken shape in his mind. .
