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

"I just keep it on my body, take it out when I use it, and throw it away when I'm done using it just now!"

Zhao Chengfeng was also too lazy to explain anything to Jin Yan'er, because he couldn't explain this kind of thing clearly.

"Okay, let's move on, there seems to be something inside!"

Zhao Chengfeng continued to explore as he spoke.

And now Jin Yun'er couldn't help being interested in Zhao Chengfeng.

She was very curious about Zhao Chengfeng's identity.

You know, she has always grown up in this village and knows nothing about the outside world.

So she felt that what Zhao Chengfeng took out just now must be something produced by modern technology.

In this way, she has made a decision.

When you go out, you must have a good chat with Zhao Chengfeng, and ask him what the outside world is like.

Then she followed in Zhao Chengfeng's footsteps.

At this time, the two came to an open place, and Zhao Chengfeng stopped.

"Brother Feng, what's the matter?" Jin Yan'er walked up and asked.

"Where should I go?" Zhao Chengfeng looked at the three caves in front of him and said.

Jin Yan'er didn't know which hole to go to, she went up to check it carefully, and scratched her head.

And Zhao Chengfeng started to use the system to scan the three cave entrances.

The system did not detect anything in the first two holes.

But at the last hole, the system detected a very strange fluctuation in it.

Zhao Chengfeng immediately decided to go in and find out.

"Jin Yun'er, this way!" Zhao Chengfeng called Jin Yun'er over.

Seeing that Zhao Chengfeng had already walked in, Jin Yan'er followed immediately.

"Wait for me, Brother Feng!"

"Brother Feng, is there anything in here?"

"Brother Feng, is there any danger!"

Along the way, Jin Yaner kept asking questions.

Zhao Chengfeng was a little speechless.

This girl's curiosity is too strong, she just wants to break the casserole and ask the bottom line, and she won't stop until she finds out the bottom line.

"Keep your voice down, what's the danger if you're afraid later!" Zhao Chengfeng could only use this to scare her.

Now Jin Yan'er still trusts Zhao Chengfeng, and when she hears that there is danger, she immediately shuts her mouth and stops talking.

Then Zhao Chengfeng continued to explore inside, and finally came to the end of the passage of the cave.

The result was an empty field again.

But this open space gave Zhao Chengfeng a different feeling.

He found that this place seemed to be excavated artificially, and it was not a naturally formed place at all.

Moreover, the passage they came in just now is different from the previous passage, and it is also manually excavated.

So Zhao Chengfeng felt that this place seemed to be a mine.

There are still many potholes that have been dug by people.

"Brother Feng, did you find anything?"

Seeing Zhao Chengfeng's puzzled face, Jin Yan'er immediately came up to meet him.

"This should be a mine, Jin Yan'er, you should investigate carefully next to it, and see if you can find traces of someone else's digging!"

"Okay, I'll look for it now!" Jin Yan'er immediately went to look for it.

And Zhao Chengfeng used the system to detect the things inside.

Suddenly, he discovered a shocking secret, which made his face change drastically.

Because he used the system to detect the existence of the unknown substance he had been investigating, and the content was still very high.

In other words, this is the mine vein of that mysterious unknown substance.

Now Zhao Chengfeng finally knew why the high-level clues about the mysterious substance that the system gave him pointed to the Xiangxi area.

I didn't expect that there are veins of this kind of material in the western Hunan area.

And looking at it like this, it has already been mined twice.

"Ding, strong radiation has been detected, please protect the host! Please protect the host!"

At this moment, the voice of the system suddenly came to Zhao Chengfeng's mind.

It turned out that the mysterious substance had strong radiation before it was mined.

Zhao Chengfeng didn't hesitate, and immediately exchanged his reputation for two radiation-isolated decorations from the system's mysterious mall.

"Jin Yaner, come here!"

"Brother Feng, what's the matter? Did you find anything?" Hearing Zhao Chengfeng's shout, Jin Yan'er immediately ran over.

Zhao Chengfeng handed one of the ornaments to her.

"Put this on your body. There is strong radiation here. Once it enters your body, something will go wrong!" Zhao Chengfeng handed one of the ornaments to her.

For Jin Yuner, of course she has never heard of radiation, so she is also at a loss.

But still put away the ornaments.

She wanted to ask something else, but Zhao Chengfeng had already started to explore and didn't give her a chance to ask.

After a while, Zhao Chengfeng found a stone slab on the ground with some writing-like things engraved on it, which caught his attention.

He dusted off all the dust on the slate, revealing the true face inside.

It turned out to be a notebook of absenteeism, which seemed to be left by the people who used to mine this substance here.

"Brother Feng, what is this?" Seeing that Zhao Chengfeng's investigation had progressed, Jin Yan'er immediately walked over.

"Jin Yan'er, do you know the words on it?" Zhao Chengfeng asked, pointing to the things engraved on it.

It is not difficult to see that this is an ancient text.

Jin Yuner looked carefully, but shook her head.

"Brother Feng, I have never seen this kind of writing!"

"What's wrong? Is there something wrong with this thing?"

Zhao Chengfeng nodded.

He looked carefully, and after comparing the materials Sun Xin and the others brought over, he found that the characters engraved on it should belong to the ancient Miao people, which was very difficult to understand.

So Zhao Chengfeng decided to print these words first, and then investigate carefully what was recorded on them after returning home.

Afterwards, Zhao Chengfeng entered the system's mysterious mall again, and found a complete set of rubbing tools inside.

"Ding, congratulations to the host for successfully exchanging rubbing tools. It has been distributed to your backpack, please pay attention to check it!"

The system's voice rang.

Zhao Chengfeng immediately opened the backpack and took out the rubbing tools inside.

Jin Yuner was stunned again.

Now she is really more and more interested in Zhao Chengfeng.

Then Zhao Chengfeng saved all the words on the time with rubbing tools.

"Brother Feng, what do you think are here?" After the investigation, Jin Yan'er was even more puzzled about this forbidden place. The things inside were all things she had never seen before.

"Actually, this is a mine vein, and the ore here can extract a mysterious substance!"
