At the beginning, he crossed over to become the cannon fodder villain's father

Zhao Chengfeng then explained the specific things to Jin Yuner.

He guessed that this place should belong to the vein of that mysterious substance, which must have been mined in ancient times.

Moreover, it seems that there are two possibilities for the ancient battlefield outside.

The first is that they fight for this piece of mineral veins, causing the two sides to fight head-to-head.

The one who comes in to mine last is the one that wins.

But he felt that there was another possibility. Maybe these people were infected by this mysterious substance, causing them to become irritable and then kill each other, which led to the scene outside.

But Zhao Chengfeng knew that no matter which possibility it was, it was inseparable from this mysterious substance.

So what he can be sure of now is that this mysterious substance must have been known in ancient times, and its efficacy is likely to be used by people.

In this way, Zhao Chengfeng also thought of this cave.

He wondered if it was because there were veins of this substance in this cave, and the people in the village sealed it as a forbidden area in order to prevent future generations from having accidents because of this substance.

Thinking of this, Zhao Chengfeng immediately called Jin Yan'er over.

"Jin Yun'er, do you know why this cave was sealed as a forbidden area by the villagers? Is there any secret hidden in it? Can you tell me?" He felt that since Jin Yun'er is a witch, she must know about these things a lot.

But in fact, he was the one who had a high opinion of Jin Yuner.

Hearing Zhao Chengfeng's words, Jin Yan'er also shook her head.

"Brother Feng, I really don't know about this. If I had known, I wouldn't have wanted to come and investigate all this time!"

"But I think you are right. There must be a reason why this cave has been sealed as a forbidden area!"

Zhao Chengfeng didn't ask any more questions.

Since Jin Yan'er didn't know, he could only investigate by himself.

Then, he continued to explore the vein.

Because he has a radiation-blocking ornament exchanged from the system, Zhao Chengfeng doesn't have to worry about being infected by radiation, and he just started looking for it.

Through his exploration, he found that the vein has already been half mined at present.

Moreover, these traces of mining are very old, and it seems that they were all made by ancient people.

Moreover, there are still many raw ores that have been mined on this ground and have not been transported away.

Zhao Chengfeng didn't know if there were any veins of this substance outside, so he decided to take some away.

If there is no outside, he can also use these ores to investigate.

This scene happened to be discovered by Jin Yaner.

She immediately ran over with a puzzled look on her face.

"Brother Feng, what are you doing? Why did you take this away? Is this some kind of treasure?" She asked, blinking.

Zhao Chengfeng smiled.

"This is not a treasure, but a raw ore of a substance. I will take it back and investigate carefully to see what is in it!"

"Oh, so, why don't you take more, it's useless!"

Zhao Chengfeng almost burst out laughing, this girl really doesn't feel bad for something that belongs to her.

He can't hold too much, after all, these ores are not light.

"It's okay, this is enough, I'm not selling it!" Zhao Chengfeng said with a smile.

After that, he continued to look at the situation of the cave, and after using the system to scan it, he confirmed that there was nothing else to do here.

In this case, there was no need for him to investigate further, and then Zhao Chengfeng called Jin Yan'er over.

"Jin Yan'er, let's go, it's been so long since you've been out, you should go back too!"

Jin Yan'er nodded. Regarding Zhao Chengfeng's words, she now has no intention of going against it.

At this time, the outside of the mountain top is actually not very flat.

This Jin Yuner is a witch, so she is naturally protected by many people.

At first she wanted to come to this forbidden area, but those people thought there was nothing wrong, so they agreed.

But these two days had passed, and Jin Yan'er hadn't come back yet. They immediately came to the forbidden area and wanted to pick her up.

But when they got here, they found that Jin Yun'er was still inside the forbidden area and hadn't come out.

Those who came to pick her up were very anxious.

Because after Jin Yaner entered the forbidden area, there was no news.

But in this forbidden area, they can't force their way into it, so they can only look for it in some places at the entrance of the cave.

But there is still no news, they are all starting to think about what to do next.

At this moment, they saw Jin Yan'er walking out of the cave, and immediately went up to meet her.

"Miss Jin, where have you been? Why did it take you so long to come out? We are all so worried!"

"You have a special status, but you must not run around!" They looked worried.

"It's okay, I just got lost inside, so I wasted some time, so I'm coming out!" Jin Yaner prevaricated casually.

Those who came to pick her up naturally couldn't say anything more.

"That's good, that's good, Miss Jin, let's go back now, you have been out for two days, so you still need to go back quickly!"

They immediately wanted to take Jin Yuner away.

But at this moment, Zhao Chengfeng came out from the inside. These people were shocked and immediately surrounded him.

"Who are you? Why are you inside?" They immediately surrounded Zhao Chengfeng.

"Quick, there are enemies, everyone is ready to fight!"

I don't know who gave the order, but these people took out their weapons and got ready to fight.

Zhao Chengfeng was confused by these people.

I didn't expect them to be so irritable, and they were about to attack immediately.

"Say, what do you do?"

"If you don't say anything, then don't blame us for being rude!" An old man, who seemed to be the leader of these people, pointed at Zhao Chengfeng and shouted loudly.

"Village chief, don't talk nonsense with him, this kid looks like something good, look at the clothes he is wearing, I don't know where they come from!"

"That's right, village chief, he must be a spy, don't waste time with him, let's kill him quickly!"

The rest of the villagers are also fiercer than each other, and they seem to rush to deal with Zhao Chengfeng.

Just when Zhao Chengfeng was ready to do something, Jin Yaner immediately ran over.

"Stop it all!"

She scolded, and everyone stopped their movements.

Zhao Chengfeng couldn't help being a little puzzled, he didn't expect such a young girl like Jin Yan'er to have such a high status among these people, which he didn't realize just now.
