Rachel's village was not far from Harrom, and the place she was talking about was near the village.

"What is it, brimstone?"

The development of stone tools in this land is very prosperous, and there are various materials of stone, many of which are jade that were sought after in the previous life.

Jun Qianqian doesn't understand jade, this thing is too deep, as a high school student who was influenced by a chemistry teacher, she prefers precious metals to gemstones.

Do science students still chase diamonds? Not to mention that it is all marketing/marketing methods, but in terms of composition, it is the same as coal.

But she knows that jade is a thing that generally exists in complex geological conditions, such as hot springs, volcanoes, and so on.

"What's that?"

Rachel hadn't heard of brimstone.

"Well, let's take a look at it first."

Charcoal is easy to say, but there is no saltpeter, and even if you find sulfur, it is useless, but the resources near the volcano are abundant, and she is still very optimistic.

The result was again unexpected.

"What is this? Swarthy and slimy? ”

Rachel led a huge team to their village.

The head of their village, the one who betrayed her to the city lord, had never seen such a formation, and was so frightened that he begged for mercy.

However, he couldn't escape Sam's fat beating after all.

"We've found a treasure this time!"

Jun Qianqian pinched Luo Ze to make sure she wasn't dreaming, Luo Ze looked at her in confusion after being pinched, and raised his hand to touch her head.

What a set of such a skillful hair process.

"What is this?"

Luo Ze looked at Jun Qianqian's sparkling eyes.

"Oil, this thing is called oil, and we call it the blood of industry."

Energy is an extremely important thing in all times.

In my previous life, I have been studying controllable/nuclear/fusion/change, just thinking that one day the energy on the earth will be used up, and human beings can still take a spaceship to other planets, otherwise they can only be trapped on the earth and wait for death.

When they found the coal mine in the Baiyan tribe, Jun Qianqian already felt that God treated them well, but they didn't expect to find oil today!

Forgive her for her lack of knowledge, as a country with great difficulty in oil exploitation, almost all of China's oil reserves are difficult to use underground.

She once saw a news that the motherland's exploration technology had made a qualitative leap, digging a 5,000-meter-deep pit in the northwest and successfully extracting oil.

Jun Qianqian's history teacher immediately exclaimed:

The technological leap or something was forced, and they had to dig 5,000 meters of pits to dig up the oil, and the toilets in the shopping malls in the oil-producing areas came out of the oil.

Who to reason with this gap?

And at this time, Jun Qianqian's excitement probably wanted to shout at the history teacher, teacher! I also saw oil bubbling from the flats! Awesome!

"This thing can be lit, but it will make a strange smell, and the stone basin will be burned open, and we tried to use this thing as fuel in the early years, but it didn't work at all."

Rachel looked at Jun Qianqian's excited expression and explained to the villagers who came over.

The villagers tried to drain the oil inside, but soon the oil would come out again, and they tried to bury it in the soil, but it was like a bottomless pit, and it didn't take long for it to collapse into an oil pit.

"The composition of oil is complex, of course, there is no way to burn it directly."

It is said that it is oil, but in fact, those who have seen this thing know that its texture is not flowing like edible oil and sesame oil, it looks closer to solid, sticky, and exudes a pungent smell.

This thing can't be used to cook for warmth, but it's just right to use it to burn puppets!

"With this thing here, the city lord doesn't have to be afraid to come over in person."

During the preparation time, Jun Qianqian told the villagers all the things they saw in the palace, and how scary they were.

In the story, Valen, who was cheated by the two of them, was told to be more terrible than evil spirits.

This is a very rough pre-war mobilization, in the face of people who are not their own, Jun Qianqian doesn't bother to think about any impassioned pre-war speeches, they will try their best to help, just want to control the damage here, don't leave the trouble to the people of the Purple Flower Tribe.

With weapons and antidotes, the double guarantee makes the villagers in each village have an unprecedented sense of resistance, even if the amount of antidote is not enough, but they don't know the usage and dosage, what if this thing can be diluted and used?

She'll remember to keep a bottle for herself anyway.

Besides, her attention was mostly drawn away from oil.

"What do you think?"

They were making improvised trebuchets with palm fibers wrapped around stones as cannonballs, which were lit and fired when the time came, while the rest of the villagers dug fire barriers.

"This one has to find a way to get the purple flower back."

Jun Qianqian pointed to the oil puddle and said.

"Is this really that good stuff?"

Luo Ze also looked at this black thing seriously, this place is far away from the purple flower, and these oils are heavy and pungent, how can he transport it back safely and quickly, he has no special way for the time being.

"Actually, we are not in such a hurry, we are not short of resources now."

With Zihua's current level of development, the coal mine is completely sufficient, unless she gets the internal combustion engine out first, otherwise the mixture of oil against the sky is really asking for trouble.

She knows the principle of separating oil, and it is enough to use physical fractionation.

But what she understands is only the theoretical method of the laboratory, and she doesn't know how to fractionate oil in large quantities in industry, and there are also many technical difficulties that need to be broken through.

But such a piece of treasure is placed on the ground, which is really gluttonous.

Not to mention cars, now Jun Qianqian is looking forward to having a walk-behind tractor, as well as the straight asphalt road, whether it is farming or transportation, the changes that oil will bring are earth-shaking.

"There's always a way."

Unexpectedly, when they went out, the inheritance of the sacrificial platform did not find a shadow, but they found rich resources, and this land still has infinite unknowns, waiting for them to discover and use.

"I'm a little overjoyed, and there's still an enemy on the way."

Jun Qianqian patted her cheeks and let herself calm down quickly, they just taught the villagers the method, and they didn't think about taking over the position of command, they were outsiders, and they still didn't want to cause unnecessary trouble.

And these villagers were noisy for a long time, and simply let Sam, Rachel, and Linda, three locals who had followed outsiders to "study", temporarily serve as their commander-in-chief of the battle.

The three of them looked confused, how could they have ever touched this!
