"The second formation. ”

"The third, fourth, fifth"

When the seventh formation is crossed.

The two had already traveled about a kilometer.

Ning Feng groaned.

The Blue Wing Secret Technique, Qingshan Shield, if you use it with all your might, without interference, the light blocks the breath of the two people, and it can last for about an hour, but if you reduce the energy intensity, it can last for about four hours.

The Rubik's Cube Stone, which can shield the induction of the Heavenly Machine Secret Technique, can only be used for three hours.

In just three hours, it didn't seem enough to Ning Feng.

During this time, they have to look for the center of the hedron mine, they have to dig for the best spars, and they also have to be vigilant around to avoid being discovered.

Before coming, Lin Nantian said that everything was ready, and the plan was very good, but the difficulty was not low, and the crisis situation would exist.

This kind of thing is to be spelled out.

Ning Feng took a deep breath and glanced at his watch, which was a watch given by Li Xiaoxi, and the time was exactly eight o'clock.

"Start accelerating!"

Ning Feng's voice fell.

He took out a Rubik's cube and shattered it.

Wisps of energy surrounded the two.

The cyan wings behind Ning Feng even cast a layer of pale cyan shield, blocking the aura of the two of them.

"Big brother, I'm speeding up!"

Wang Xiaofan grinned, and the golden god shovel began to speed up the digging pit.

The two of them walked forward underground like gophers, passing through defensive and warning formations, and heading towards the bottom of the main city of Luo No. 2.

At the same time, above the ground.

"Lin Nantian, you will pay for this. ”

The strong men of the Luo tribe have appeared.

Hundreds of thousands of teams gathered in a short period of time.

"Daredevil, you're taking yourself seriously. ”

"We didn't trouble you, but you came to the door, do you want to die?"

"Don't forget, we still have the support of the Ice Hand Clan in the midstream battlefield, who do you have?

Many Luo powerhouses ridiculed.

"Less nonsense, kill!"

Lin Nantian took the lead in the charge, and the war was about to break out.

It's not a fake fight, it's a real fight.

In the face of the attacking Lin Nantian, the strong people of the Luo clan were angry.

Lin Nantian, he was also a member of the Luo tribe, but now his hatred for the Luo tribe is even deeper.

Lin Nantian is also good enough, just because he is very strong, and the powerhouses of the Luo clan have a killing heart for him.

Because of Lin Nantian's existence, it is a joke for the Luo people.

When many people talk about Lin Nantian Lin Demon Shuai, they will mention the Luo clan.

Boom Boom!

The high-altitude battlefield took the lead in fighting.

The huge team below is also attacking each other tentatively.

The battle that took place outside the city gate attracted the attention of most of the Luo powerhouses.

No one noticed that there were two people in the underground who were getting closer and closer to the hedron mine.

Wang Xiaofan digs forward quickly.

Twenty minutes later.

"Wait!"

Ning Feng suddenly spoke.

Wang Xiaofan stopped, there was a little sweat on his forehead, and he asked dizzily, "What's wrong, big brother?"

"There's a dark river ahead. ”

Ning Feng frowned slightly.

His mind sensed that a hundred meters ahead, there was a dark river.

The dark river is surrounded by boulders, it is a confined space, there is a strong current in the river, and monitors, detectors, warning instruments, etc., are very dense.

"This dark river, underground, should completely surround the hedron mine. ”

"How do you get there?"

Ning Feng groaned.

"What Dark River?"

Wang Xiaofan didn't take it seriously, he said: "I can also dig the river, my god shovel is invincible, big brother." ”

"Keep digging. ”

Ning Feng nodded, and took out thirty-six gems.

Water Hidden Array!

This formation in the Thousand Arrays can achieve the effect of stealth in the water, deceiving vision, but it cannot escape the perception of thoughts.

This formation is enough to deal with these cold instruments.

The two of them walked forward quickly, and when they dug into the dark river, the formation effect appeared, and the energy of the green mountain shield blocked drinking water.

The river is about thirty meters wide.

Wang Xiaofan blocked the entrance of the cave in the future, dug forward, and blocked the entrance, which did not affect the flow of the dark river.

The front is still deep underground, and the warning formation still exists.

Continue digging for twenty minutes.

"Big brother, I'm tired, otherwise you can take me over, big brother?"

Wang Xiaofan wiped the sweat from his forehead and said.

"You can't use the Escape Technique, the breath will be sensed. ”

Ning Feng shook his head slightly, took out a bottle of recovery potion, and handed it to Wang Xiaofan: "Keep digging, we'll dig the spar mine right away." ”

According to the distance, it is already very close.

The underground of the main city of the Luo tribe is also unusual.

In addition to formations, there are also various hard stone slabs.

Digging these will accelerate the consumption of Wang Xiaofan's energy.

Really!

As Ning Feng's words fell, he continued to dig for five minutes.

They came to the edge of the hedron mine.

The ground was full of rubble, and in the cracks of the rubble, they saw a low-grade spade.

"It's here!"

"Dig out the center. ”

"Go on. ”

The direction can only be tried, digging forward, and encountering more and more low-grade spars, indicating that they are closer to the center.

But digging and digging.

When!

Wang Xiaofan suddenly dug the same passage.

Ahead is a tunnel with a brilliant wall of lights.

And it's guarded!

Groov!

Ning Feng's heartbeat skipped a beat!

The stones blocking the tunnel can shield the perception, and Ning Feng doesn't know the situation ahead, even if the excavation speed is already very slow, he still digs a twenty-centimeter gap in the tunnel.

Extremely fast stones fall to the ground.

"What sound?"

Not far away, someone was talking, and footsteps were heard, and the sound was getting closer.

"Big brother!"

Wang Xiaofan's eyes slowly widened.

Is this going to be discovered?

Ning Feng held his breath, and the two of them followed the entrance of the cave, looking intently at the side.

I saw three Luo people, slowly walking towards this side.

Knock knock, knock knock

At this moment, Wang Xiaofan could hear his accelerated heartbeat.

The situation has become critical.

There was silence all around.

Not even the sound of breathing.

"What's that?"

Several small rocks were found on the ground.

They walked briskly.

Eldest brother!

Wang Xiaofan's arm trembled.

Isn't this yet an escape?

If you don't leave, it's too late!

Oh, my God!

They're coming!

Wang Xiaofan's mouth was wide open, and in his gaze, three people approached, and one of them picked up three small stones.

"It turned out that my hedron had fallen. ”

"It's shameless, this is my spar, right?"

"Hehe, I also grabbed a few spars, exactly three, one for each person, and I don't know who dropped it. ”

I saw the three of them, one of them picked up a piece, put it in the space treasure, and then patrolled forward.

It was as if they couldn't see the notch in the wall at all.

What's going on?

Wang Xiaofan was stunned, turned his head sideways, and saw Ning Feng lying beside him, with three gems in front of his palm, and after careful sensing, Wang Xiaofan found that there were wisps of energy that were difficult to sense, and they were surrounding a range of several meters in front of him.

"Illusion Formation. ”

Ning Feng exhaled a long breath: "Dig down, go over here." ”

As he spoke, Ning Feng quickly blocked the gap.

Dig down.

Unexpectedly, this place is like a floor, there are tunnels in front of it, and the compartment of the tunnel is only about half a meter.

"The defense of the hedron mine is amazing. ”

Ning Feng sighed with emotion.

At this moment, he had a little tingling in his scalp.

Lin Nantian said, the Luo clan's spar mine is the easier kind, and their special means are not very many, if it is a race with special talents, it is tantamount to a joke to dig other people's spar mines.

"Crawl over. ”

Ning Feng pointed to the compartment between the two tunnels.

But unexpectedly, there were a lot of wires in the compartment.

Headaches.

Ning Feng fell silent again.

After thinking about it, I still have to go inside the tunnel.

Stealth?

Stealth!

As long as you can evade detection.

"What formation?"

"Phantom Flow. ”

Ning Feng took out thirteen gems, crushed them, controlled the energy, and hid in the dark after forming a formation.

When a small team passed by, the two went out quickly, Wang Xiaofan held a shovel, dug a gap under the tunnel, and the two got in.

After plugging the gap, move on.

There are more low-grade spars here, and a lot of them can be perceived all around.

Moments later, they came across a second tunnel area.

After crossing in the same way.

The area in front of it has become a medium-grade spar.

Moving on, there is another tunnel area, and then there is the high-grade spar area.

"Don't take it, keep going. ”

Ning Feng couldn't help but want to get some spars.

This is a high-grade spade, a high-grade spar is equal to a hundred medium-grade spars, and it is equal to 10,000 low-grade spars.

If you can take dozens of pieces, it is equivalent to hundreds of thousands of lower grade crystals.

However, the number of high-grade spars is very rare, and there is only one piece within a few cubic meters.

Endured, the first time Ning Feng did this, he was also a little cowardly, afraid of being discovered.

Keep moving forward.

Finally, Ning Feng felt that thirty meters in front of him, there was a circular energy body.

The energy body is a continuous formation.

What is protected in it, it goes without saying!

The best spar!

In the core area of the spar vein, it is precisely because of the existence of the best spar that the spar mine is a renewable resource.

A spar mine is a whole, the position of the best spar cannot be moved, and the quantity must be strictly controlled, once it is destroyed, the spar mine will become a dead mine, and no new spar will be born.

"Dig it up!"

Soon, the two of them reached the front of the circular energy.

"This is a layer of protection. ”

"Dig slowly. ”

"Be careful. ”

The situation in front of the formation, Ning Feng couldn't perceive it.

But Wang Xiaofan dug the formation, did not destroy the formation, and could still let the two of them pass.

Very successful digging, after the two passed.

Again, the situation has become uncomfortable.

The surrounding stones are pure transparent stones.

In the cracks of the many stones, there are sparkling sparkling crystals.

Each hedron contains a lot of energy.

However, under the transparent stone, the figures of the two were on the edge, and once they entered it, it was easy to see, because in the center of the best spar area, there was a space, like a room, in which sat an old man!

Obviously, this old man's strength will be very strong, and he is the one who guards here.

What to do?

Use the hidden formation to drop the hedron bag?

The superb spars around are like stars, very dazzling, and the two of them are really acting under the noses of others, which is too arrogant.

Ning Feng didn't dare to bet.

"There's an old man in front, big brother, what should I do?"

Wang Xiaofan asked in a low voice.

Ning Feng's expression was very calm, and his brain was running fast.

"It can't be helped. ”

Ning Feng took a deep breath.

What the?

Do you want to give up?

Wang Xiaofan was stunned, thinking that the two were leaving, who would have thought, Ning Feng said such a sentence:

"I can only go to bomb mines!"

"Huh?"

Wang Xiaofan was dumbfounded.

He followed Ning Feng and quickly went backwards, running a relatively long distance.

In Wang Xiaofan's gaze, Ning Feng kept taking out gems, about a hundred.

Then, in the area of medium-grade spar.

Boom!

The Big Bang has appeared!

After the fluctuations of the explosion appeared, Ning Feng and Wang Xiaofan had already returned to the side of the best spar mine.

Really!

The old man in that room, when he heard the movement, suddenly opened his eyes, and his gaze was extremely sharp.

He followed the hallway, opened a metal door, and quickly left, going to inquire.

"Quick!"

"Action!"

"We don't have much time!"

Ning Feng said hurriedly.

The two of them came here quickly,

Wang Xiaofan broke out!

Click, click, click

The god shovel swung quickly, and the speed of digging the hole was as fast as the flowing water of a river.

Here, the best spars are shining, like coordinate points, and the two of them dig through them accurately.

There were about 100 top-grade crystals in total, all over the place, and with Wang Xiaofan's excavation speed, it took just three minutes.

Ning Feng collected fifty pieces of top-grade crystals.

"Quick, go on!"

Seeing that Wang Xiaofan was sweating profusely and slowed down a little, Ning Feng reminded:

"After digging this time, we will get rich! Keep working hard, after this time, we can rest for a long time!"

"I dug it!"

Wang Xiaofan gritted his teeth and continued to burst out of strength, and the speed of digging the pit became faster again.

Ning Feng quickly collected pieces of top-grade spars.

At this moment, Ning Feng was also very nervous, and he could also hear his heartbeat.

It feels like dancing on the tip of a knife!

Thrilling and exciting!
