Artifact

In the midst of the heat, a series of whining sounds suddenly came out from the top of the tunnel, and the strange sound like a bell was like a shock wave through the layers of tunnels, sweeping in!

Huo Duhu let out a low shout: "Fire!".

The half-people quickly extinguished all the torches and hid one after another, and for a moment the atmosphere froze and silence was like nothing.

Immediately after that, there was a second sound, a third sound.

The

sound of the earthquake rumbled, the debris fell in the tunnel, and the dust floated everywhere, and the underground was like this, so you can imagine how terrible the sound would be on the ground.

After about a pillar of incense, there was no strange sound, everything returned to normal, Huo Duhu lit a torch with his own hands, and the room returned to light.

Night Thirteen asked, "What's going on?"

Huo Duhu replied: "This is the alarm of the demon beast. In the middle of the square is an urn beast with a large hollow bulge on its back, which makes a loud noise when struck. Something big must have happened on the ground, otherwise it wouldn't have been!".

Night Thirteen and Xue Ling Xue Xiang looked at each other, could it be that the body of the spider ape was found?

Everyone quickly explained the situation, Huo Duhu couldn't help frowning, he didn't expect things to be much worse than he imagined.

Xue Ling said: "Lord Night, Huo Duhu, without further ado, we must act immediately, otherwise the demon beasts will find this place sooner or later by following the smell!"

Huo Duhu pondered for a moment and said, "Lord Night, let's be honest, the tunnels in the Extreme North Pass are much more complicated than we expected, and the pit road lines that Commander Yu Rang asked us to write down are actually less than one percent!"

"The passage here not only runs underground, but also extends to the main buildings in the city, which may have been built to monitor the generals of the Far North Pass. "

"If you want to find someone tonight, you can snoop through the intricate secret passages here...... It's just that even though we've been dormant here for months, we still can't fully uncover so many secret passages. "

Night Thirteen understood what Huo Duhu meant, although when the Extreme North Pass was built, it was presupposed that many dark passages went straight underground, but it was used to monitor people, and the noses of humans were very low-level, no matter how powerful they were, they couldn't compare with the demon beasts.

Assuming that a half-human person acts in the dark passage under the floor, the demon beast can easily find out, which will not only save the life of the spies, but even expose the existence of the secret passage.

This plan seems to be usable, but in fact it is a dead end!

When he was at an impasse, Xue Xiang suddenly thought of something: "Lord Ye, Huo Duhu, the slave family has a plan! The strategy of investigating through the secret passage is not impossible, but we have not thought of a way to improve it." "

"Demon beasts mainly rely on their sense of smell for what they can't see, which means that as long as they can't smell it, or if they smell 'wrong', they won't reveal the location of the spies and secret tunnels!"

As soon as these words came out, Huo Duhu patted his head and suddenly realized:

"Clever plan! I can send people out to investigate, inquire about the little monsters engaged in hard labor in various places, kill them, and smear them all over their bodies, so that they will not be discovered when they move in the secret tunnels!"

Xue Ling echoed: "Yes, the hard labor demon beasts roam around the city, leaving their smell everywhere, plus we are not completely human, we will not emit the smell of irritating demon beasts, so as long as we are careful, we will definitely not attract the attention of the demon beasts!"

Night Thirteen also felt justified when he heard it, and it seemed that there was only one option to choose from, so he agreed to this plan.

Huo Duhu's spirit was shocked, and he immediately arranged for people to carry it out, first of all, he would investigate all the hundreds of major buildings in the entire Far North Pass, and if he still couldn't find You Long'er, he would make plans again.

On the other hand, Night Thirteen proposed a second plan, which was to leave the safety of the pit and return to the surface.

There is also a reason why he wants to return to the ground, the main reason is to confirm whether the matter of the spider ape has been exposed, and the second is to engage in some sabotage, distracting the attention of the demon beasts for Huo Duhu and the others to carry out the task, which is also the so-called sound of attacking the west.

At the third o'clock, Night Thirteen didn't say that he was going to return to the outside of the Far North Pass and study the prison pit where hundreds of thousands of people were imprisoned.

Don't forget, there are tens of thousands of Yan Hui dead soldiers mixed in the crowd, if these people have a glimmer of life, they will definitely be able to fight their way out of the beast tide!

But Ye Thirteen's idea was opposed by everyone, Huo Du Hu needless to say, he finally looked forward to a backbone, and he counted on Ye Thirteen to stabilize the army's heart.

On the other hand, the two sisters of Xue Ling and Xue Xiang felt that the danger factor would increase a lot if they went out now, after all, Ye Thirteen was a human being, and if it was smelled by any of the demon beasts, it would be a major event that would affect the entire wave of beast tide!

In desperation, Night Thirteen had to spit out the third thought, and everyone fell silent when they heard it.

The people present are all half-humans, and they are also the dead soldiers who volunteered to come, they are ready to die and understand that Yan Hui will never come to help and ambulance, but now there is such a person as Night Thirteen, who admires these dead soldiers and wants to save them.

How can this not make people's hearts surge?

Compared with the soldiers of the Yan Kingdom in the past, I gave my life for the Yan Kingdom, but the dog officials of the imperial court were talking about it, even the Yan Hui Organization was just using the blood of countless dead soldiers to fill the endless battlefield - in the eyes of half people, the night thirteen who can practice it is no different from the savior who came from heaven!

Xue Ling said: "Lord Night, in this case, the slave family is willing to accompany you!"

Xue Xiang directly hugged Ye Thirteen's arm: "Sister, I have the help of empty pupils, I can see through a few zhang, Lord Ye is not fighting with demon beasts, but just waiting for an opportunity to move after investigation, I am the most suitable to go!"

Xue Ling seemed a little annoyed, and she raised her slap to scare her: "Xiang'er! Don't mess around!

This time, Xue Xiang didn't back down at all: "Sister, you beat you!" Xiang'er knows that my sister wants to protect me, but at this time, the night master is more important than our sisters, isn't it?!

".

Night Thirteen said: "Don't fight, I don't bring anyone, one person is enough." It's just that...... I'm going to ask you to borrow some more urine. "

Although the sisters' faces were crimson, they suddenly fell silent like deflated balls.

.

Since the only exit in the Extreme North Pass was above the wine cellar, and it was occupied by demon beasts, Huo Duhu and the Xue sisters sent Night Thirteen to the farthest exit outside the city, which was also the last safe entrance and exit of the underground tunnel.

At this entrance, you only need to dodge the monster beasts that are scouting from the air, and it is relatively easy for half-humans to hide, while humans basically can't escape the flying monsters with sharp noses.

Although Night Thirteen wore clothes mixed with the strong smell of urine of the sisters, as soon as he opened his mouth, he would immediately reveal his stuffing!

Seeing Night Thirteen disappear outside the tunnel, Huo Duhu and the sisters turned around and returned.

Huo Du said: "I really don't know what we half-humans have accumulated in our previous lives, God sent Lord Ye to help us." Beixue Shuangjiao, I will also arrange a part of the route for you to explore, the night adults can't be sloppy!".

Xue Ling said: "Yes, Huo Duhu, I will complete the task as soon as possible, so that I can help Lord Ye as soon as possible!"

After Xue Ling finished speaking, Xue Xiang didn't move, she looked back, where was Xue Xiang's shadow!

She was shocked

"Xiang'er, this girl, is it possible to chase the night adult?!".
