Chapter 705

When the children returned home, they saw their families cooking food. They ran over and threw the withered grass into the bonfire.

But this time, the child was in great trouble. After a while, the black withered grass got into the fire, and it was burning violently.

It also releases a lot of smoke and bad smell.

At this time, the cooking food could not be eaten, and almost burned because of the sudden explosion of the campfire.

The incident attracted many tribesmen to investigate and finally saw the liquid on the children's hands.

People finally know that the strange liquid can burn.

However, after experiments, the ancestors of Weiyang tribe found that it was difficult to ignite the liquid directly.

Even stabbing a burning stick into the liquid will extinguish the flame on the stick.

But if the liquid is attached to something, it will burn well.

Slowly, the ancestors of Weiyang tribe successfully developed this kind of liquid lighting, and finally applied it to the royal mausoleum.

It also gave it a very vivid name, burning water.

After listening to the story of Wei Yuhan, Zhao Fengnian was filled with emotion.

What I had been looking for but couldn't find was just treated as a poisonous liquid in a remote corner.

It's true that Zhao Fengnian was so curious about the fuel used for the lighting of the Royal Mausoleum because of the smell it emitted when it burned.

Zhao Fengnian is also familiar with this smell, which is the exhaust gas of various vehicles often smelled in the previous life.

If Zhao Fengnian is right, the black liquid is the crude oil of oil.

Petroleum crude oil is a kind of gray black viscous or thin liquid, through fractionation and other processes, according to the specific gravity can produce gasoline, kerosene, diesel, and other very important chemical raw materials.

When the well of Weiyang tribe was opened, a water vein flowing through the underground oil layer was inadvertently opened.

In that case, there may be one or more large oil reservoirs in the area of Weiyang tribe.

Oil is also what Zhao Fengnian has been looking for. The liquid fuel fractionated by it has the characteristics of light weight, easy to carry and large energy release, which can be applied to many places.

I really made a lot of money this time. I found such an important fuel in the beginning.

However, I don't know whether the Weiyang tribe has been occupied by the wolf tribe. If so, I'm afraid it will take some effort.

Taking back his mind, Zhao Fengnian closed his eyes and felt that the world was still in chaos.

As a result, Zhao Fengnian could not know whether the world's oil is like coal, whether it contains a trace of aura.

If so, it will be of great help to the future survey.

Since his perceptual ability failed, he could not go to Weiyang tribe to explore the specific situation. Zhao Fengnian opened his eyes and looked at the confused people.

Zhao Fengnian said with a smile: "let's go. We have good luck this time. I hope we can have such good luck next time."

With that, Zhao Fengnian put down the oil barrel and walked into the depth of the Royal Mausoleum under the guidance of the rain culvert.

The design of the royal mausoleum is very magnificent, and the whole structure is a building layer by layer.

After the death of the king of Weiyang in the past dynasties, the tombs were all designed, leaving a certain space.

I don't know whether it's a coincidence or that the ancestors of Weiyang tribe have the ability of prophecy.

After the last king of Weiyang tribe was buried, there was only one tomb left.
