The entire construction site was full of chaos; black liquid was sprayed out, and a pungent smell spread; and in the pungent smell, there was a faint strange feeling that couldn't be said; if you insist on expressing it, it was like a rotten and dirty breath.

If spiritual energy is a lively and vibrant existence, then this breath is a dead breath!

After ecstasy, Li Xian finally had to face the reality - this black liquid is definitely not oil, or it is not just oil! This oil seems to contain many, many dangerous things!

Gradually, the decadent and dirty breath made Li Xian feel uncomfortable.

Everyone panicked up the hillside, allowing the construction site to be flooded with black liquid.

The black liquid seemed endless, and soon turned the valley into a vast ocean and a black lake formed.

Li Xian looked carefully and found that the black liquid surface seemed to have colorful spiritual light flowing; however, the colorful spiritual light was very weak, and it was more of a purple-black spiritual light flowing; in addition to purple-black, there were also gray, black, dark blue, etc., which did not seem to be a good existence anyway.

Ge Zhengfeng next to him was thinking about this, but he was just talking vaguely. Li Xian couldn't hear clearly what he was saying.

However, Li Xian was still very curious and wanted to come forward to get some samples.

Unexpectedly, Ge Zhengfeng grabbed Li Xian and said, "Don't go over, you're not going to die!"

"Senior Ge, what is this?" Li Xian was really curious.

"The turbid air underground! Didn't I just say it!"

"It's just the turbid air underground?" Li Xian widened his eyes. What you said was too simple.

Ge Zhengfeng looked at the black lake in front of him and seemed to be thinking about something. "There is a saying that the Immortal Realm has been born for countless thousands of years, not just human races, but in fact, human races have only risen in recent tens of millions of years.

Especially in ancient times, there was plenty of spiritual energy in the world, geniuses and treasures were everywhere, and monsters were rampant; human race could only survive in the cracks.

After these powerful creatures die, they will slowly decay and gradually sink into the ground. The corpses of these powerful creatures contain powerful power, including the aura of fairy spirits, the aura of demons, and even many powers that we don’t know now.

These forces have been decaying underground for countless thousands of years. After fermenting, they form this strange black liquid. These liquids contain powerful forces mixed together. The colorful streamer is actually an extremely weak fairy spirit. Unfortunately, no one can extract it, and no one dares to extract it!

Also, this liquid often contains the residual souls of ancient powerful monsters or some vicious breath. Once people come into contact with these liquids, our souls will be dispersed!

Look, many craftsmen who are stained with turbid air will slowly fall down!"

Li Xian looked at the black lake that was constantly expanding in front of him, but he was quickly thinking. Obviously, although this is not the oil from another world, it can also be regarded as the oil from this world! No matter which kind of oil it is, it is a treasure!

But the treasures of this world seem to be even more dangerous, and there are still residual souls! If you are not careful, you will die!

Li Xian was excited and accidentally discovered oil!

But on the other hand, he was very confused. Looking at the craftsmen who kept falling to the ground, Li Xian frowned - the oil on the earth is not so dangerous!

Ge Zhengfeng looked at it for a long time and finally sighed, "Fortunately, it's not that such a thing happened at the end of the project. Fortunately, we have gunpowder. Let's change the place."

Next, we will count the number of people, more than 1,000 elites and more than 3,000 various craftsmen who were gradually transferred, and more than 500 died! No one was injured, only those who died! As long as they were contaminated with the liquid, their souls would collapse and die. The residual souls and wills of these ancient powerful men were obviously not something that ordinary foundation-building stage could withstand.

A faint sense of sorrow spread throughout the team, but the imperial tomb still needs to be built.

Everyone walked around again. After detailed calculations, Ge Zhengfeng actually chose to continue excavating on the other side of Yunding Mountain. Yunding Mountain is very large, with a radius of more than 20 miles. If you dig in another place, be careful, there is no problem at all.

But from this day on, Li Xian kept frowning and thinking, how can he use these treasures? No matter in that world, oil is an absolute treasure!

There must be some things in the oil of this fairyland: the aura of immortal spirit, a large amount of spiritual energy, some strange medicinal power, the origin of the strong after refining, etc. Maybe the bones of divine beasts can be found in this liquid, etc. - You must know that the oil and coal mines on the earth can often see fossils!

On this day, Li Xian came to the front of the black lake here to watch again. As the number of views increased, Li Xian probably had a data analysis - among these black liquids, at least 5% of the spiritual energy is still there! It is liquid spiritual energy! This is judged based on flowing light.

In other words, a hundred kilograms of black liquid can extract 5 kilograms of liquid spiritual energy! Liquid spiritual energy is definitely comparable to low-level spirit stones. Based on experience, especially the experience of the spiritual stone formation process seen in the consciousness world, Li Xian estimated that a kilogram of liquid spiritual energy would be about ten ordinary low-level spirit stones!

In addition to spiritual energy, there is also the aura of fairy spirit. However, the aura of fairy spirit is too little, and often a wisp of colorful light smoke flashes and disappears immediately without a trace. But this is the aura of fairy spirit after all! If it can be extracted, even if the entire lake can only extract one or two of the aura of fairy spirit, Li Xian will work hard!

In addition to spiritual energy and fairy spirit, Li Xian also found that there were some pure auras here. These auras were as thin as hair, but they were like naughty elfs, flashing in the black liquid, with various colors.

Of course, the most black liquid is the existence of the black liquid; Li Xian felt that it should be oil. However, this oil is not ordinary, because there must be a large number of mixed fermented substances such as body remains of ancient powerful people, such as strength and soul.

"This is a treasure! This is an absolute treasure! If I can find a way to separate and refine, then... I will no longer have to worry about energy and spiritual energy!"

Unfortunately, the prospect is brilliant, and I am helpless at the moment. Li Xian caught countless wild animals from the mountains for experiments, but as long as he touched a trace of liquid, he would be ruined!

"The future is brilliant, the future is beautiful, the future is brilliant, the future is very... But what should I do now?"

Li Xian is so miserable; he has tried to dream at night these days, but it seems to be unsuccessful!

Just as he was worried, Song Xing's voice came from behind him, "Young master, Mrs., Madam is here to deliver the letter."

Li Xian immediately stopped being upset. After taking the letter, he started reading it. As he looked at it, Li Xian smiled, "Haha, we have a good vision. Isn't the good wife and Qingqing the ones said?

Listen, listen, good wife, Lee Hyun’s inner helper!”

Song Xing next to him laughed hard - the name of the young master is so amazing, brother, good wife, nephew... everything can be related to you!
