Seeing that there are not many lights on the island, Ye Chen guessed that there is no such thing as lamp oil on this island.

If it doesn't, it's really difficult to have lights all the time.

Like those firewood, I am afraid that if all the trees on the island are cut down, it will not last long.

Something that can keep burning.

This old Mr. Liu waited for someone to think about it, and soon realized it.

"Ye Sect, there really is."

really have?

"Where? What kind?"

"There is a place on the island, but it is easy to collapse there. Many people have died before, and now they dare not pass."

"Now take me to see."

Since there is something that can keep burning, I definitely want to check it out.

Ye Chen, Gu Ling, Tang Ling'er, Gui Lao followed them.

At that time, Mr. Liu and the others had stopped, and then pointed to a place ten meters away and said, "Ye Zhangmen, there is a place that is easy to collapse. There are dark things that can be ignited. It burns for a long time."

Something dark?

Is it petroleum crude oil?

Crude oil, in fact, was discovered in ancient China, but it was not used in large quantities.

Now, when Ye Chen heard it, he thought it was something like oil. Even so, he thought it was pretty good.

However, that place is easy to collapse, and it is difficult to get it out if it collapses, indicating that the area is all around.

If you pass light work, you can easily take it out.

"Dharma protector, go and see."

When the groom put on the oil lamp, he quickly entered inside. Sure enough, the closer he got to the inside, the more obvious the feeling of collapsing.

I feel that the soil here is all soft.

Of course, he suspects that the following are the dark things these people are talking about.

I squatted down at the groom and saw it soon, but I saw that it was dark, but the smell was not a pungent thing, and I was using a wooden barrel to take out a part.

When he brought it out, Mr. Liu and the others were surprised.

Unexpectedly, this old gentleman was so powerful, as if nothing happened at all.

After taking it out.

Ye Chen looked carefully.

He discovered that this shouldn't be petroleum crude oil, but another substance, which instead seemed to be left over after a certain animal died.

Ye Chen just tried this dark thing and found it easy to light.

This can really burn.

He doesn't know how much of this black fuel is under here, but if it can be taken out and used, it will be different when there are lights on the island.

"Ye Sect, you are really too good, so take out the black mud easily."

Old ghosts and horsemen are all ancient martial artists, and the people on this island are just ordinary people. They are naturally incomparable with horsemen.

Now Ye Chen first helped the people on the island take out a large amount of black fuel.

It took about four or five hours. Now every household has the black fuel, and then he took it back and ignited it directly. On the originally very dark island, every household now has these lights inside and out.

Although it is still incomparable with the lights of big cities, it is indeed different when there are lights.

On islands where there is no sun, these lights can now be illuminated, at least improving the lives of the islanders here.

"Ye Sect, you are really our god, thank you for helping us."

However, in Ye Chen's view, they will not be long before they will leave the island. Therefore, he still has to leave a set of good methods to at least allow these islanders to go there freely to dig those black drinks. .

Because the individual is too heavy, it is easy to collapse.

And there is only one result when it collapses, which is a dead end.

In this case, Ye Chen felt that other methods could be used.

Explaining according to physical principles, Ye Chen felt that if a large piece of wood could be used, it should be possible to wipe out the black fuel.

Even so, it is still very troublesome.

Ye Chen thought of a way to pass the ship again.

That is to say, in a safe place outside, a channel with water is dug, leading to a place with black fuel, and it can be rubbed and transported out by this method.

Now Ye Chen asked the members of the Tang Sect to find a way, they were better at these organ techniques.

Ye Chen didn't expect that Tang Wu and the others were really powerful, and they could even use the kinetic energy generated by the black fuel to develop an automatic machine, which could wipe and dig there by themselves.

In that case, Ye Chen left this matter to Tang Wu and the others to deal with it.

Anyway, the black fuel distributed to these islanders can be lit for at least a week or two.

And Ye Chen needs to learn more.

The life of ordinary people is nothing more than food, clothing, shelter and transportation.

It is even more so on this kind of island, because money is of no use here, mainly to solve the problem of food, clothing, housing and transportation.

However, most islanders cannot even solve these problems.

In terms of eating, Ye Chen also saw that in addition to the wild fruits and wild vegetables, there are many fish in the endless sea outside, but many islanders are also dead on fishing.

And now Ye Chen’s idea is that now that there are lights here, he can build a simple greenhouse, where plants and vegetables can be grown.

The grains and some beans brought on their ships can be used for planting.

"Ye Zhangmen, can these really be planted?"

"If it was in the original situation where there was no light, it would be impossible to plant it, but now that these lights are on, it is actually possible."

Ye Chen felt that the rice, wheat and beans that he brought over could be grown.

They couldn't eat wild vegetables all the time, so Ye Chen felt that it could be improved.

Like these, Ye Chen handed it to Mr. Liu and the others, and set out a place to train them first, and then see how effective they are.

These will take time.

Of course, like cultivating bean sprouts, this also takes two or three days.

In addition, the aspect of eating.

In Ye Chen's view, meat is still needed.

On their island, Ye Chen didn't see any animals such as livestock, not even birds.

In this case, we can only rely on the mountains to eat the mountains and the water to draft water.

In other words, they can rely on the endless sea to catch those sea animals.

"There should be many big fish in this endless sea, and they can be fished. You don't have to live so hard."

"Ye Zhang Sect, it's not that we can't do it, but our ability is too low. Many people have died on the island because of fishing."
