At that time, Lin Wu was talking on the phone with someone, and suddenly Bo Liu's excited voice called her outside: "Miss Lin! Miss Lin! My master is back!"

Lin Wu glanced outside and said to the person on the other end of the phone, "Check this matter first. If there is no suitable manpower, you can disguise yourself and sneak in to do it. Make sure there is someone to supply you later."

The person on the other end responded respectfully: "Yes! Don't worry, I will definitely get it done for you!"

Lin Wu thought for a moment and added, "If I haven't come out of the mine before tomorrow afternoon, you go find Third Brother. He will find a way to get me out. But you don't have to come over. Just keep an eye on your side and don't let anyone take advantage of you."

After giving the instructions, Lin Wu hung up the phone, opened the tent curtain and went out.

At a glance, I saw a familiar car parked not far away. Bo Yuting was about to get out of it and was talking to Bo Liu.

Zheng Mingxian and Guan Chen had heard the noise and rushed over, standing beside him.

Guan Chen handed Bo Yuting a gas mask to put on.

The black fog under the mine stopped spreading this morning, but the air was already filled with a fine mist. It didn't seem like anything at first, but if you smelled it for a long time you would still feel dizzy.

Suddenly, Bo Yuting turned his head and met Lin Wu's gaze accurately.

He nodded at her, indicating that he was fine and everything was going well, and then he strode towards her.

Seeing this, Guan Chen and the other two followed.

As they got closer, Bo Yuting reached out his hand to Lin Wu, held hers, and said softly, "I got some unexpected gains, so I came back a little late. Let's go in and talk."

Lin Wu went in with him.

Zheng Mingxian was the last one to come in. He hastily instructed the people from Xuanmen to keep guard and not let anyone get close before following in.

Inside the tent, Bo Yuting first asked what was going on in the mine and why there seemed to be fewer people.

Bo Liu was quick to speak and quickly told him what had happened from last night to this morning. He also said, "Not only those people left, but nearly half of the people from the 17th Regiment also left. Only the red-haired beauty and two others remained. Mr. Guan sent them to the infirmary."

It can be said that the people left in the mine are all tough guys.

Bo Yuting frowned slightly, "So many people were driven away. It turns out that the people in the forbidden area attach so much importance to this place. It seems that the news I received was correct."

"What news?" Lin Wu asked.

Bo Yuting said: "Let's start with the black fog."

He took out a document, opened it and handed it to Lin Wu.

Lin Wu took it and looked through it, and Guan Chen and Zheng Mingxian couldn't help but come over to look at it together.

Bo Yuting said: "This black fog is very strange and its ingredients are complex. I studied it for a whole night and found that it contains at least ten ingredients that are difficult to identify with current scientific methods. It can only be preliminarily determined to be toxic. Long-term contact will cause indelible damage to the human body."

"What?! Then Cheng Man stayed down there for so long, which means..." Zheng Mingxian's pupils shrank.

Bo Yuting said: "It is possible that Cheng Man has already... Unless he finds a suitable hiding place down there and can avoid contact with the black fog as much as possible."

Zheng Mingxian’s eyes went dark and he fell onto the stool, stunned.

Lin Wu asked in a deep voice: "What else?"

"The rest is more interesting." Bo Yuting motioned Lin Wu to turn to the back and said, "You would never imagine that you have also come into contact with the only few components I could detect in the black fog."

"……I?"

Lin Wu was stunned.

Lin Wu lowered his head to look at the data presented on the paper, reading ten lines at a glance, but was suddenly stunned when he saw something.

She pointed at those lines and said hesitantly, "This looks familiar. I seem to have seen it somewhere before. It's..."

With a flash of inspiration, Lin Wu suddenly looked up at Bo Yuting.

Bo Yuting nodded and confirmed her: "Yes, it is the physical condition of the people who were experimented on with Phoenix Tattoos at the ninth dock in Beijing. I have seen a considerable part of the data a few days ago, so I am quite familiar with it. So when I got these data this morning, I felt familiar with them, and I thought of them all at once, and spent a long time making comparisons. In the end, it was confirmed that those experimenters had this black mist in their bodies."

That's one of the reasons why he came back now.

Guan Chen knew everything and said in surprise: "In other words, this black mist is one of the raw materials for making that kind of tattoo?"

Zheng Mingxian didn't know what they were talking about, and asked in confusion: "What tattoo, what's the composition?"

Lin Wu replied to him: "You don't need to know for now."

Zheng Mingxian was confused, but he didn't say anything else.

Bo Yuting continued, "I have checked the existing information and carefully studied this black mist. It cannot be used directly as a raw material. In addition, I found that part of its molecular structure is in a damaged state, as if it has reacted with something. In addition, this is a mine, and the minerals that Shi Ying used for tattooing were extracted from ores..."

Lin Wu understood.

"You mean, there is a kind of ore under this mine that can be used to make that kind of tattoo. And that kind of ore can release this black mist?"

Bo Yuting nodded: "That's right. Now that the black mist is spreading to the ground, something must have happened underground, causing a large amount of ore to be destroyed, resulting in the current situation we see."

Guan Chen said, "So the reason Black Fox found traces of the Huo family here was because of this ore? They want to mine this ore to continue making tattoos?"

Bo Yuting: "It's obvious. Besides, the Huo family only appeared here recently, which means they discovered the ore they need not long ago, but they may not be sure, so they have to find someone to identify the stone quality and judge whether it is really what they need based on the results of the stone quality."

This is how Zheng Mingxian's experience happened.

Guan Chen was surprised and said, "But this mine is a forbidden area. If you say so... the forbidden area is the Huo family's background?"

As soon as these words were spoken, the atmosphere in the tent became noticeably stagnant.

Lin Wu frowned.

As one of the four top forces in Continent R, the Forbidden Area is very tricky. If they and the Huo family are really... But the problem is, she knows who the owner of the Forbidden Area is, and it doesn't seem like he has any relationship with the Huo family.

Bo Yuting said: "No, I know the Lord of the Forbidden Area. He has absolutely no relationship with the Huo family."

Lin Wu looked at him.

Bo Yuting squeezed her palm soothingly and said, "This is about the interesting things I found out this morning."

"After confirming that there was something that the Huo family was interested in, I asked someone to look up the previous trading records and background of this mine. This mine was bought by someone from the Forbidden Territory six years ago. At first, it was quite profitable, so the people from the Forbidden Territory didn't care about the remoteness of this place and continued to run it reluctantly."

"But three years ago, the amount of stone available for mining in this mine was getting smaller and smaller."

"Two years ago, something happened here. A customer who wanted to buy ore from here came to us and said that there was something wrong with the ore they were selling recently. People who had used it had physical problems, and some died suddenly due to their physical condition worsening. This incident caused the mine's business to take a sharp turn for the worse. Although the people in the forbidden area suppressed it and compensated those people appropriately, the news eventually leaked out."

"So after that, the mine gradually lost business, and several unexplained mining accidents occurred, and it became the dilapidated state we see today."

Lin Wu smelled something wrong: "Is there something wrong with the ore? This black fog is spreading upwards from the deep layer, which means that the poisonous ore is very deep below. They have no more ore to mine and continue to go down. Did they mine this poisonous ore by accident? And there is a mining accident... Why is the cause unknown?"
