The miracle doctor came down from the mountain and opened a restaurant to raise his daughter

The entrance to the cave is natural, but once you enter, you can see obvious artificial traces.

In particular, there are two railway tracks extending inward on the ground.

Cables as thick as wrists and some electric lights were hung on the walls of the cave on both sides.

The power source is a large generator set at the entrance of the cave.

It is relatively flat within a hundred meters to the front, and there are not many traces of artificial excavation.

But after a hundred meters, it was completely manual excavation.

Moreover, the diameter of the hole has changed from the original three meters to only one and a half meters in diameter. At this height, people have to bend down to walk.

Both Chen Ning and Zhen Luogui could feel that the hole extended downwards at an angle.

You must know that this is a valley itself, and if it continues downward, the depth from the top will be at least five to six hundred meters underground.

The workers in the mine had evacuated in the past two days, but there were still some scattered tools and even some small crushing machinery left in the mine.

It is too far away from the outside world and is impossible to pass by, so even if you go out and buy some tools again, the cost is lower than the transportation cost.

A group of four people followed the narrow mine and went inward for about a hundred meters and stopped again, because the hole in front became smaller here, and they could only squat forward if they wanted to go in.

You can imagine how uncomfortable it was for the miners to work under such conditions.

When they arrived here, Chen Ning and Lian Zhen Luogui both clearly felt that the aura here was a little richer than outside. This made the two of them look at each other and see the joy in each other's eyes.

"This is the situation. Does Butler Zhen have any questions?"

When Zeng Qingdong showed Zhen Luogui here, it was equivalent to the completion of the inspection, and subsequent matters were no longer under the control of his Zeng family.

"No more, let's go."

Zhen Luogui waved slightly to Zeng Qingdong.

Zhen Luogui didn't even bother to say any kind words to such a little person.

Zeng Qingdong didn't take it seriously. Anyway, the other party had no objections, so his final handover work was completed, and all the reminders that should be done before were done.

With a brief farewell, Zeng Qingdong led his men out of the mine.

"Chen Ning, this must be the Yuanjing vein. You can feel the spiritual energy here. I want to practice here."

After the Zeng family left, Zhen Luogui could no longer maintain his calmness and said with deep emotion.

"Then you can practice. I will continue to dig deeper and strive to dig out the Yuanjing mine here as soon as possible."

Chen Ning smiled lightly.

It's good to practice properly here, but he didn't come here to practice.

And even if you want to practice, you have to be closer to the crystal vein mine!

"Mining? Yes, mining. Who is still practicing here after digging up the Yuan Jing?"

Zhen Luogui came back to his senses and nodded repeatedly.

Chen Ning ignored Zhen Luogui and continued walking deeper into the mine, with Zhen Luogui and Chen Ning behind him.

Although the cave became more and more difficult and narrow the further inside, the spiritual energy became stronger and stronger, making the two of them more and more excited.

only……

"Why does it feel hotter and hotter? Shouldn't it be getting colder?"

Zhen Luogui followed and walked a few dozen meters before speaking with doubt.

Chen Ning also felt it.

However, he did not answer Zhen Luogui directly, and tried his best to sense into the surrounding stone walls.

Originally, Chen Ning's perception could detect a radius of two hundred meters, but here it was greatly restricted, only twenty meters at most.

In other words, the perception here is suppressed ten times, mainly because the density of the stones here is relatively high.

Soon we reached the end of the mine.

There was a mine cart loaded with gravel standing in front of him. Chen Ning waved it away, mainly blocking his way.

Then he turned his hand and took out another dagger...

"Are you going to dig with this?"

Zhen Luogui blinked when he saw Chen Ning taking out his dagger.

At first glance, this dagger is much more advanced than my own treasure. It might be a real cultivator's flying sword!

"What else do you think?"

Chen Ning said lightly.

Then he waved his hand and slashed out with the light golden sword energy.

I saw a gap up to one meter deep being cut directly into the stone wall in front of me.

Then there was another sword coming across.

Wow!

The gravel around the cross gap was scattered directly, and the mine was as deep as one meter forward.

As for Gravel, Chen Ning directly earned the Five Rings.

Zhen Luogui opened his mouth slightly, is this okay?

He kept the treasured dagger on his body. After taking it out, the dagger was filled with real energy and he slashed at the stone wall in a similar manner.

puff!

A gap of thirty centimeters appeared, which looked very powerful.

but……

It was just a gap. Even if he struck the sword again, it would not be able to break all the surrounding stone walls into rubble like Chen Ning did.

Zhen Luogui was embarrassed, Chen Ning glanced at him with a teasing smile, and then continued to swing the dagger, pieces of gravel fell off, and then were put away.

If those who bring machinery to open a mine see it, they will definitely shout "Holy shit, can a mine be mined like this?"

Chen Ning's advancement speed is really not slow. After all, he can reach a depth of one meter with two swings.

In the blink of an eye, Chen Ning extended the hole ten meters inward.

Among them, several round stones rolled out, and Chen Ning collected them as gravel.

These round stones are actually raw jade stones.

However, Chen Ning checked and found that there was no Yuan Jing inside.

Chen Ning also opened a one-meter hole at the beginning, which could save some effort and time.

When they were ten meters away, they expanded the cave wall a little, allowing themselves and Zhen Luogui to stand up straight and take a short rest.

As for the lighting problem, any practitioner can handle the night market.

"How deep do we have to dig?"

Zhen Luogui asked, following behind Chen Ning.

At this time, the spiritual energy did not become thicker, but the temperature in the air obviously increased.

I estimate that the temperature here should be thirty-five or six degrees now.

Of course, this temperature has no impact on practitioners.

"I don't know. There's nothing we want within a radius of at least twenty meters. It's probably about a hundred meters." Chen Ning said calmly.
