Soon after Li Yi'an released the signal arrow, four breaths appeared in his perception.

He immediately dodged into Tunnel One, disappeared into the darkness, and hid his aura.

It wasn't long before four figures appeared at the entrance of the tunnel.

There were several war beasts around them, probing the aura around them.

...

Tunnel Zero was completely excavated by Zhenyuan bombing that year, and a lot of manpower and material resources were used to repair it in the later period.

The space inside the tunnel is more than enough for low-altitude flight.

The main road is not completely straight, but curved, with a certain slope that extends towards the ground.

The same is true for the side roads that are connected to the main road, and the situation is more complicated within the side roads.

After Lin Chong and the others entered the main road, they flew towards the depths of the main road.

Their purpose is clear, they are here for that 'legacy'.

But Li Yi'an's previous release of the signal arrow was too big.

Even Lin Chong, Fang Long and the others had already entered the tunnel for a long time when they heard the sound of signal arrows exploding.

They have been preparing for this operation for a long time, the purpose of which is to let Zhang Ling and Miao Dongqing fight and attract the attention of others.

They took the opportunity to infiltrate Tunnel Zero.

Now it's good, Li Yi'an released signal arrows at the entrance of the tunnel, and also released them as fireworks.

...

The four of them searched around for a while, but found no clues.

It didn't take long for the four of them to put away the war beast and gather together to discuss.

"My war beast hasn't found any clues, what about you?"

The other three shook their heads when they heard this, and they also found nothing.

One of them scolded: "Damn, what the hell, who is making trouble?"

"I don't know, but his purpose must be to attract Zhang Ling or Miao Dongqing!"

Everyone nodded, they had this idea too, and it was dangerous.

"Is it possible that we misheard? Didn't the sound come from the tunnel entrance?"

"Impossible, even if we hear it wrong, will Senior Brother Lin Chong and Senior Brother Fang Long also hear it wrong?"

The man shook his head and said, "It should... No, but Senior Brother Lin Chong said that this sound is like the signal arrow of the Feather Arrow Sect, who is so bored to use the signal arrow to set off fireworks... Poisonous. ”

The crowd looked at each other, and they themselves became suspicious.

Even if it was really the signal arrow of the Feather Arrow Sect, which disciple of the Feather Arrow Sect would prepare so many signal arrows?...

"Forget it, put away the war beast, Xiao Cheng and I will stay, and you go back and report it. ”

One shook his head and said, "What do you want to stay?" This is too loud, if Zhang Ling and Miao Dongqing hadn't died, they would definitely come here to investigate, how would you explain it then? ”

Another person also said: "Yes, the No. 4 branch road smells of blood, and it can't be covered, and when they come, you will also die!"

After the four of them discussed, they decided to go back together to resume their lives, after all, not only would they not gain anything if they stayed, but they might also die.

...

Li Yi'an watched them leave behind them and walked out of the shadows.

Previously, he wanted to blend in with Lin Chong's team and obtain information, but now there was no need.

What kind of inheritance are you looking for? It's almost the same as finding death.

This is a forbidden place, and neither Zhang Ling nor Miao Dongqing will ignore the rescue signal here.

Previously, no one came to investigate after Zhang Hu released the signal arrow, which shows that the battle situation in the No. 3 living area is stalemate, and both sides cannot get out.

Of course, if he is like this, someone will inevitably come to investigate.

But he was afraid that the people who came would not know the purpose of Lin Chong and the others, so he had to work hard to show them the way.

There were more than a dozen bodies of the Overseer in Branch 4, and he could have pretended to be one of them.

Li Yi'an has a confident guess that the probability that the person who came is Zhang Ling is very high.

"This tunnel is complicated, I'm a kind person, it's my duty to show the way for others, hehehe...", thinking of this, Li Yi'an couldn't help laughing.

“...”

...

Soon, Li Yi'an came to Branch No. 4 and found the body of the monitoring team.

The temperature outside was cold, but inside the tunnel it was noticeably warmer.

Although these people didn't have many wounds, they piled up, and there was still a strong smell of blood coming out.

Li Yi'an picked and chosen, and finally chose a guy who looked slightly pleasing to the eye and lived for him again.

Soon, the trick mask, the change of clothes, some injuries on the body, a few holes, for him to be caught.

After doing all this, he scratched the faces of several people and put his true yuan in an extremely unstable state.

Then he lay down in the pile of dead people, not forgetting to spit out a few mouthfuls of blood.

...

It wasn't long before there was a sound of footsteps outside the tunnel.

There were a lot of people coming, very many, otherwise Li Yi'an wouldn't have heard the sound outside in Tunnel No. 4 at all.

The perception extended outward, and Li Yixin smiled secretly, it was indeed Zhang Ling's person.

To his slight surprise, Miao Dongqing actually followed.

"Senior Brother Zhang, the people from the supervision team are gone..."

Zhang Ling's face was cloudy and uncertain, and he was on the verge of outburst.

Miao Dongqing was no longer cynical at this time, because the situation was indeed out of control!

It's clear who is going to attack the supervision team in Tunnel Zero.

That so-called neutral force is really well hidden.

After several years of plotting but not moving, once he saw blood, he pointed directly at Zhang Ling.

Of course, something really happened to Tunnel Zero, and Miao Dongqing thought that he couldn't get out safely.

Cooperation?

Soon, reason told him that he should choose to cooperate...

Miao Dongqing glanced at Zhang Ling, who was carried away by anger, and then made a search movement for the people behind him.

Soon, the bell rang, and one after another war beasts searched the way ahead, and everyone followed.

Soon after, Li Yi'an noticed that someone had entered the No. 4 branch road.

The corpse was not far from the entrance of the branch road, and several war beasts poured into it along the smell of blood.

Li Yi'an was soon surrounded by these war beasts.

Zhang Ling's subordinates recognized the identity of Li Yi'an's pretended disciple and immediately ran up.

"Lao Luo, are you okay, what's going on here?"

Li Yi'an opened his eyes in a daze, and after a violent cough, he spit out a few mouthfuls of blood...

Blood Pupil muttered to herself, I really want to act...

Li Yi'an ignored the blood pupil, leaned his back against the wall with the help of the man, and spit out the words with difficulty.

"Someone attacked!"

"It's... Lin Chong, and Fang Long..."

With a pop, Li Yi'an spurted out another mouthful of blood.

He doesn't have the memory of this person, and when the person is dead, the blood pupil has no way to extract the memory.

I can only say less, to the point, the injury is serious, don't ask more, if you ask again, I will die!

After Zhang Ling stepped into the branch road, his breath couldn't stop releasing it, and it could be seen that he was extremely angry about the situation at this time.

"What about them!", Zhang Ling asked word by word.

Li Yi'an stretched out his hand and pointed in a direction and said, "They went to the depths along the main road, many people!"

Zhang Ling disappeared in a flash when he heard this, Miao Dongqing followed, and the rest of the people followed the two of them in a hurry.

Tunnel Zero, the first tunnel to be developed, was closed just a few years ago.

Previously, many of the team had worked in the tunnel and were familiar with the terrain.

These words in the depths of the main road made the hearts of several of the 'old men' twitch.

Lin Chong and the others don't want to die, they don't want to die yet!

If what happened back then happens again, they may all die without waiting for the walkers to come back!

Of course, in the eyes of Zhang Ling and Miao Dongqing, Lin Chong and others are for inheritance.

arranged such a big scene, why did you Lin Chong take advantage of the fisherman.

If there is really a inheritance and you get it, you will have to spit it out!

One after another, the figures flew their feet into the air and quickly flashed from the entrance of the branch road about a foot off the ground, and Li Yi'an was dumbfounded.

Too strong! Too much!

He was amazed at the cultivation of these people and their numbers.

If these people were cultivating normally, it would be impossible for them to increase their cultivation speed to such a large extent.

What's more, they are more or less disciples of the Immortal Sect who were abandoned by the sect and came here to be punished, and their own qualifications are not high.

But now that the cultivators of the Transformation Origin Realm gathered by the three forces have gathered, there are more than a hundred people...

And this is only 20 years in the history of this mine.

For a monk, twenty years is just a snap of a finger.

This strengthened the determination in his heart, and the human demon heart method must not be passed on.

Not only can it not be passed out, but if it is possible, this mine must be completely destroyed!

The aura of heaven and earth has become so thin that the consequences of indulgence will be harmed for a hundred, a thousand years, or even ten thousand years.

As far as we know so far, this situation is still an irreversible trend.

...

"Lao Luo, you don't talk much, rest now, I'll bandage your injuries and inject you with some energy. ”

Inject energy? Big brother, who are you, don't be so direct, okay...

Li Yi'an immediately refused: "No need, senior brother, you go and join Senior Brother Zhang Ling, don't worry about me, I'll go back to the living area immediately after resting." ”

The man nodded, left some healing items, and got up.

But the moment the man got up, he held a long arrow in his hand and stabbed at Li Yi'an.

Li Yi'an was slightly surprised, but reacted quickly, and immediately covered his hands with Zhenyuan, raising his hand to resist.

After taking advantage of the momentum to unload the power, he immediately supported the ground with his right hand and bounced several meters sideways.

"You found me?"

Li Yi'an said unhurriedly.

At this time, everyone had already followed Zhang Ling and Miao Dongqing to the depths of the main road.

There were only the two of them in the fourth branch at this time, and the fluctuation that this person in front of him had just exposed was the third order of the Source Realm.

Li Yi'an's cultivation was three orders higher than this person, so he was naturally not afraid, but he was curious about how his identity was exposed.

The man couldn't help but be stunned when he saw that Li Yi'an's identity was exposed, and he chatted with him, and then took out the repeating crossbow from the space ring.

"Boy, I have to say, you pretend to be very similar, but, Lao Luo, Luo Xiao generally calls me Lao Luo, not Senior Brother. ”

He calmly took out another black box, mounted it on the repeating crossbow, and aimed it at Li Yi'an.

"Tell me, who are you?"

He lightly rested his right hand on the trigger and made a defiant gesture.

There is not much space at the entrance of the fourth branch road, and the continuous shooting of the crossbow can produce extremely strong damage at close range.

But Li Yi'an was calm as if he hadn't seen it.

He looked at Lao Luo and smiled, "Careless." ”

"You seem to be very confident!", Lao Luo frowned slightly, his eyes scanned the surroundings.

Li Yi'an chuckled: "Leave the brain..."

"Oh, by the way, watch your step!"

Lao Luo frowned but didn't check his feet, "Lie to me?"

Suddenly, two flying swords burst out from under Lao Luo's feet, and the tips of the swords penetrated the soles of his feet, directly fixing them on the spot.

He just wanted to open his mouth and shout, but on the ground between his legs, the third flying sword broke through the ground.

This flying sword is not pointed upwards, but the hilt is facing upwards, and the moment it breaks the ground, it hits Lao Luo's mouth.

With a 'poof' sound, Lao Luo's big mouth that was about to open his mouth to call for help was hit hard, and his front teeth were shattered and burst out.

A mouthful of blood was swallowed, and before he could speak, he began to cough violently.

But Lao Luo didn't do nothing at this moment of panic.

Although his vision was obstructed, he had already pulled the trigger of the repeating crossbow and shot wildly towards the position where Li Yi'an was standing.

But when he came back to his senses, he found that there was no one in front of him...

His pupils dilated, and a pair of hands were placed on his back, and the fluctuations of the sixth order of the Transformation Source Realm were undoubtedly revealed.

"You...", Lao Luo was speechless in surprise.

Li Yi'an said lightly behind him, "I said, let you see what you are underneath, your brain is a good thing, just forget it!"

In an instant, a palm-sized blood-red sword body stood within half a meter of Lao Luo.

Lao Luo's brain went blank, his eyes trembled, and one picture flashed quickly...

Li Yi'an smacked his tongue secretly, the blood pupil was really too strong.

If Blood Pupil doesn't need to look at her to activate her skills, it's invincible...

Of course, how weak could the sword of the White Emperor be?

Soon, the blood pupil walked out of the sword body space and nodded at Li Yi'an.

Li Yi'an held Lao Luo's head with both hands, went up and down, and twisted it hard.

'Click', Lao Luo died.

The blood pupil flew back into Li Yi'an's sleeve, and the voice said, "Master, it's been investigated." ”

Although he had seen Zhang Ling and Miao Dongqing's people before, he couldn't estimate their overall strength.

Therefore, a very important part of the memory that the blood pupil is reading now is the battle situation tonight.

After all, he had only guessed based on various signs.

"Well, the forces of Zhang Ling and Miao Dongqing are not small in the competition. ”

"Now that the two of them have joined forces, they are almost the same as Lin Chong Fanglong's strength. ”

Li Yi'an nodded, fortunately, the time for me to intervene is just right, in this way, all the forces in the mine will be greatly weakened tonight, whether it is my acquisition of information or the absorption of the heart stone by the blood pupil.

As for Zhang Hu, he still needs to be on guard, he will definitely go back to Tunnel Zero.

The three forces are here, and there is no reason why he, the behind-the-scenes operator, should not come.

Li Yi'an took out Fan Bo's map and walked towards the depths of Branch Road No. 4.

According to the plan, he was going to go through branch 4 to branch 7, 9, 17, and finally reach his destination, branch 18.

At the same time, he also took out the two keys that Fan Bo had placed in the wooden box and put them in his arms so that he could use them at any time.

...

It wasn't long before a figure landed at the entrance of Tunnel Zero, with two turquoise blood-condensing snakes on his left and right shoulders.

On the ground, a blood-congealed snake entered Tunnel Zero before its owner, and quickly swam towards the depths of the tunnel.

"It's good, all the forces are gathered in Tunnel Zero. ”

"I'm not on the road at the moment, but what you've done is exactly what I want to do. ”

"Maybe I'll want to thank you..."

...

Li Yi'an had already entered the depths of the branch road at this time, looking for a fork to the seventh branch road.

He didn't know that Zhang Hu had also entered the tunnel at this time.

But it doesn't matter, if Zhang Hu doesn't come, he will feel strange.

Following the fourth branch road, with the help of the map of Van Bo, he quickly found the entrance to the fork.

But the sight in front of him made him frown, because the fork in the road was blocked by boulders...

After a moment, his perception slowly probed into the clogged tunnel entrance, and he breathed a sigh of relief.

The blocked tunnels are not deep, and the boulders are within their control.

'him!'

At that moment, he immediately mobilized his true essence and moved the rubble away from the blocked entrance.

It took a lot of time for him to make it to the seventh branch road.

He actually secretly regretted it in his heart, if he hadn't introduced all the forces in the mine here.

He can go directly to Branch 18 through the main road, even if he doesn't go directly, he can go to Branch 9 first, and then find a way to enter.

But there are so many people on the way now...

...

Half an hour later...

Li Yi'an poked out of the mouth of Tunnel No. 17 with a disgraced face.

The situation in this branch made him very embarrassed.

Because all the side roads are blocked!

Fortunately, it didn't take too long.

The destination of Lin Chong and the others was in the depths of the main road.

He had seen the map, and if he didn't take a break at their speed, it would take at least two hours.

There are also other problems that you may encounter along the way, such as clogged tunnels, monsters in the mines, curses, and so on.

Especially in the second half of the main road, although the main road is not dangerous, the branches that extend from the main road are marked with many monsters and strange symbols by Fan Bo.

"Master, why don't you rest first? Branch 18 has arrived, and I don't know what will happen next!"

Li Yi'an nodded, and sat cross-legged after taking a few pills to restore the true yuan.

'Misty Suo...'

'Misty Suo...'

Suddenly, Li Yi'an opened his eyes, and he heard some very strange sounds.

The blood pupil flew out of his sleeve, regained her original size, and stayed at Li Yi'an's side.

"Something closer!"

Li Yi'an subconsciously took out the dragon slaying sword given to him by the Chu madman, and his eyes were staring in one direction.

Tunnel 18, in Fan Bo's memory, is a secret place of mines.

Along the way, except for the entrance to the branch road was blocked, there were no other dangers.

But as the strange sound drew closer, he had a very bad premonition.

This kind of premonition is inexplicable, but the higher the cultivation, the more sensitive the monk will be to the sense of crisis.

This shows that something is approaching and is in great danger to him.

His blood pupils were hidden, and he did not make direct contact for the time being.

One man and one sword slowly retreated into the seventeenth branch road.

And at this moment, a strange energy came out from the depths of the eighteenth branch.

The energy was very fast, and purposefully directed towards the location of the sound.

"It's kind of interesting..."

Li Yi'an stood at the mouth of the tunnel connecting No. 17 and No. 18 with some anticipation.

Yes, it's anticipation!

He originally thought that the energy would be empty!

But upon careful identification, he realized that this energy was not void, but pure true element!

In Tunnel Zero, which is particularly valued by humans and demons, how can there be such a pure true element?

The Blood Pupil also noticed this, and after she walked out of the sword body space, she held the Blood Pupil Sword in her right hand.

"Master, do you notice?"

Li Yi'an nodded, "I sensed that this energy is at war with the object that made the sound." ”

The way they fought was also wonderful, and there was not much noise, but the whole branch trembled.

After the two sides fought for more than ten minutes, the shaking gradually subsided.

At this time, the blood pupil frowned and looked at the eighteenth branch.

"What's wrong?", Li Yi'an was a little puzzled.

The blood pupil rubbed his temples and whispered, "I think, this energy is familiar to me!"

She nodded, and confirmed, "Yes, I have been exposed to this energy, and it is very familiar! I should know the owner of this energy!"

Li Yi'an was also puzzled, how could there be someone known to the blood pupil in the tunnel of humans and demons?

And who can the blood pupil know?

Aren't they all people tens of thousands of years ago?

If this kind of existence is still alive now, I really don't know whether it is good or bad for his current situation.

"Is it the enemy, or is it?"

Blood Hitomi shook her head, she wasn't quite sure where the other party standed.

The only thing she knew for sure at the moment was that she knew and had been in contact with it.

After a while, the strange sound gradually faded away, and Li Yi'an hesitated for a moment before stepping into the eighteenth branch road with the blood pupil.

His perception became clearer.

Previously, his perception was blurred due to the flow of energy, but now he saw a lot of strange objects scattered on the ground in the distance.

"Blood Pupil, keep up!"

After he greeted the blood pupil, he immediately flew in the air in that direction.

If I'm not mistaken, it's a bug...

Li Yi'an was even more curious.

How did a swarm of bugs manage to deal with that energy fluctuation?

It didn't take long for him to stand where he had perceived the anomaly.

The ground is densely littered with the corpses of many bugs.

At this point... He picked up the body of one of the bugs and looked at it.

The blood pupil stuck out his tongue on the side, a little disgusted...

But in the next second, the blood pupil knocked the insect away from Li Yi'an's hand with a sword.

With a 'snap', the corpse of the insect slammed into the walls of the cavern, shattering in response.

Li Yi'an didn't have time to ask the reason for the blood pupil.

I saw that the corpse of the insect with the broken body twitched, and a point of light that was extremely difficult to detect with the naked eye flew out from the location of the broken corpse.

Soon, the point of light flew towards the other end of Tunnel 18.

At the same time, the insect corpses scattered on the ground began to show signs of fragmentation.

The corpse of the worm, which had just died and still had some viscous liquid around it, quickly dried up, as if the water had been drained.

The sound of 'click' kept coming.

A breeze blew, and all the bodies began to shatter, and small points of light flew in a dense direction one by one.

Li Yi'an only discovered the abnormality at this time, and it was all spiritual power!
