The underground city is in a state of madness.

The frost under the ground continued to invade every corner of the city, and the condensed frost reflected the light emitted by the orb of the dome, reflecting the terrified and twisted faces of the residents, and the loud noises from nowhere continued, each loud noise was accompanied by a strong vibration, as if a giant hammer was constantly bombarding the city, and at some point this place would be completely destroyed.

All normal activity in the whole city had stopped, because the inhabitants had no intention of paying attention to the daily chores, and a great fear hung over them, and now the only thing they could do was to kneel on the cold ground and pray.

The Blood Sect's search team was active throughout the city on a large scale, and they did not spare an inch of the rock walls at the edge of the city, so that the actions that made it easier for the residents to panic finally came with reassuring results.

According to the search, outside of the miscellaneous area and the abandoned quarry, there was no problem with the rock walls in other places, and the Holy Spirit Temple should have only dug two tunnels close to it.

The news somewhat calmed the icy aura emanating from some of the Blood Sects, and he quickly turned his attention to the huge vibrations coming from a certain direction in the depths of the rock formation.

Maybe it was out of confidence in the huge underground formation of this city, or maybe it was out of trust in Tianxian, no matter what, the Blood Sect didn't pay attention to the problem of the underground cold vein rising for the first time, which gave Tianxian a huge opportunity!

Tian Xian knew very well that the Blood Sect could not find the source of the shock, the city was deep underground, and it could be seen from the fact that there was an underground cold water river below, although this depth allowed the city to completely avoid all invasions, but in this trouble, it was impossible to find the source of the vibration that spread extremely through the thick rock formation. It's like looking for the place of an invisible speaker in a valley full of echoes.

Even if Tian Xian himself had superhuman-like five senses, he was only roughly sure that the vibration was coming from above, but the specific direction was not perceptible at all.

Now there is only one way for the Blood Sect to figure out this matter, and that is to immediately send someone to the ground to check, since the sound is coming from above, then it is obvious that this is what the Holy Spirit Temple is doing on the ground. Just go up and take a look now and you'll know the result right away.

But this is not possible.

Now that the Holy Spirit Temple has bared its fangs on the cake of the Blood Alliance Headquarters, the Blood Sect will definitely not risk exposing the entrance to the ground.

And this incident also fills part of the gap in the Tianxian plan.

Hiding all the refined waist cards in their clothes, Tian Xian and the four girls quickly rushed back to the defense line in front of the miscellaneous service area, and now the Blood Sect is stationed here, as if this is the defense headquarters.

"Lord Blood Sect, the underground cold veins are still rising, but the momentum has weakened. Moreover, the cold air began to seal the narrow crack, and it must not be long before the cold veins stopped rising because the crack was closed. ”

As soon as Tian Xian came back, he immediately couldn't wait to report this matter to the Blood Sect, of course, these words were just nonsense, even if the underground rift was frozen, but from the underground cold vein to the ground, I don't know how many large and small ventilation gaps there were, and the cold vein would definitely not stop rising.

But Tian Xian was sure that the Blood Sect would take his word for it. For these words were what he expected, and what he wanted to hear.

Really. The Blood Sect, who was studying something in front of the city map, raised his head and said with great satisfaction: "Very good, the next situation is up to you to check, and report to me the changes in the cold vein at any time." ”

When I heard this, I was more sure of my thoughts.

The Blood Sect didn't regard the rise of the underground cold veins as something that had to be dealt with at all.

Although his judgment was completely wrong, Tianxian also understood that his judgment was absolutely reasonable. Because under normal circumstances, the underground cold vein would not rise at all, nor would it threaten the city, the Blood Sect chose to believe in the laws of nature extremely rationally, even if this cold vein occasionally rose for some reason. And there are unprecedented water monsters in it, but it is by no means likely to pose any real threat to the city. Because the ancestors of the Blood Alliance chose this place and left behind a huge guardian array that no one has ever come before or after to protect the city, the Blood Sect firmly believes that the huge power that protects this city will never be the culprit in the destruction of this city.

If the sky is not idle, the Blood Sect's judgment will not be wrong in the slightest.

But the variable that Tian Xian broke into the cold vein and signed a contract with the golden-veined beast was not at all something that the Blood Sect could have predicted.

"Regarding the shaking coming from outside, I don't know if the Blood Sect Master has any clues now?" Tian Xian not only did not leave after the Blood Sect finished his orders, but also asked questions.

The Blood Sect's gaze swept through the black aura that swirled around him, "I don't have a clue yet, because I can't determine the direction." ”

"Lord Blood Sect, I have an opinion, I don't know if I should say it?"

The Blood Sect was obviously slightly stunned, and the surrounding blood disciples of the Blood Sect also immediately set their eyes on Tian Xian, the strong vibration and loud noise in the past two days were almost going to torture people crazy, but no one could find the reason, Tian Xian's words were very attractive.

"Do you have an opinion, why hesitate?" the Blood Sect asked lightly.

"Because this speculation may cause some unnecessary panic, the situation here can not withstand any more shocks. ”

"Oh?" the Blood Sect threw down the map and slowly walked in front of Tian Xian, "What do you think, just say it." ”

"Yes. ”

Tian Xian tried to make his tone humble and objective, "Although I don't know exactly where this sound came from, when I walked through the city, I saw what was the biggest impact of this sound on us?"

The Blood Sect couldn't help but look at the trembling residents of the miscellaneous area who were kneeling on the ground, "You mean those scared waste?"

"Exactly!" Tian Xian became serious, "This kind of shaking and loud noise has not caused us any substantial harm, but it has caused us unprecedented chaos, and it is still constantly putting pressure on us, Lord Blood Sect might as well think about it, if this is a deliberate result, then who will be the culprit?"

There were a few crackling sounds of bone joints from the Blood Sect's hands. "You mean to say that this is the ghost of the Holy Spirit Temple?"

"Yes! It's very likely now! The previous explosion, and the current tremors and loud noises, are disrupting our vision and destroying our spirits, and this tremor is happening at this time. It also keeps coming, and it looks like it's artificial. ”

"Proof!" the Blood Sect lowered his voice, "What evidence do you have to prove your words, and ...... What can you do about it, even if it's a ghost on the mat? If it's just your unfounded speculation, then it's pointless. ”

"This guess is naturally meaningful, otherwise I wouldn't dare to speak casually in front of you in the Blood Sect. Tian Xian first put on a high hat for the Blood Sect, then raised his head, his eyes flashed with spark-like brilliance and said, "I guess the people from the Holy Spirit Hall are on the ground. And there are ways to prove my words. ”

The Blood Sect stared at the sky for a full minute, and then said slowly, "Okay!

The method of day leisure is simple.

A team of people was quickly mobilized to hang large semi-fixed hedron on the rock wall in the distance, these materials are different, and the use of these hedras is also different, some precious and some cheap spars have only one function - to reflect light.

The person who proved it this time was the Blood Sect itself, and according to the line of sight of the Blood Sect, a small row of such gems hung from top to bottom in the entire underground city, through the rock wall and all the way to the dome. Far and near, it is subject to the fact that the Blood Sect can clearly see these spars at the same time.

The jewels in the dome that glowed like sunlight shone on the hedrons, making them sparkle. Tian Xian asked each spar to face the brightest side towards the Blood Sect, and looking forward from the Blood Sect's side, a shining circle appeared along the ground, rock walls, and dome of the entire city.

"Lord Blood Sect, please pay close attention, the next shock is coming soon!"

This strong vibration is extremely regular. It happens every once in a while, and gradually the frequency seems to increase.

When a violent tremor hit the city, not only the Blood Sect, but all the Blood Disciples who were paying attention to Tian Xian's proof move widened their eyes and showed a look of surprise on their faces.

It is difficult to discern the direction of the vibration by listening to the sound. But the eyes were not so confused, and when the tremors came, the hedrons on the dome were the first to tremble, and the light that had been reflected to this side was biased elsewhere, and the aura that spanned the entire city was the first to lose its brilliance at the top, and then the rest of the place was gradually dimmed by the tremors.

Although this is not extremely subtle, it is enough to distinguish clearly.

Tian Xian called people to try it several times in a row, and each time it was the same result.

All the blood disciples couldn't help but look at the dome, if this tremor came from above, then there was a chance that it was not a natural earth tremor, let alone some geocentric monster moving, and in the end, it might be someone doing something on the ground.

And if it is really artificial, then it seems that the Holy Spirit Temple is plotting the only explanation for what is.

The dome that the Blood Sect was staring at seemed to be deep in thought, and when everyone began to quietly discuss what to do, he seemed to finally think about the result.

Turning to Tianxian, the Blood Sect said: "Very good! Really good! You came to our Blood Alliance, which can indeed become an existence that can be our absolute help, you can form an alliance with us with peace of mind, I promise that I will never treat you badly." ”

Tian Xian smiled modestly, "Lord Blood Sect is serious, but even if we know this, we still don't know what the other party is doing, we are still relatively passive, it is better to ......"

"No!"

Before Tian Xian finished speaking, the Blood Sect had already interrupted, "No one will leave here now, let alone go to the ground to investigate the situation, this city is extremely strong, it is absolutely impossible to be destroyed, the Holy Spirit Temple is intimidating us, but this also shows that they can't break through here, as long as we stabilize our position, they will soon be unable to hold on and retreat, this is ...... The best way!"

Tian Xian naturally didn't refute, just nodded, "What the Blood Sect Master said is right, since that's the case, then I'll go back and monitor the situation of the underground cold vein first, if there is anything I can help, please call it at any time." ”

"Go ahead. ”

Tian Xian returned to the dilapidated house where he had refined the waist card before, and only stayed here for less than five minutes before immediately turning back.

As expected, the Blood Sect was no longer in the miscellaneous area.

Knowing that the Blood Sect had temporarily returned to the Blood Alliance Hall to rest, Tian Xian showed a victorious smile and turned around to return the same way with the four girls.

This time, Tian Xian had a full grasp in his heart.

"The Blood Sect must have some way to know the situation on the ground. ”

In the re-repaired dilapidated house, Tian Xian quickly polished the waist cards that had just been refined, and made some old marks such as scratches on them, making them look exactly like the real thing.

The fourth girl followed Tian Xian on the side to polish the waist card together, her face was slightly hesitant, "This matter has never been determined before, and I have never heard of anyone in the Blood Alliance who has a way to know the situation on the ground." ”

Tian Xian smiled slightly, "But this is very strange, right, in your own territory, but you can't know the situation above your head, this is completely unreasonable, since the city chose to be underground, then naturally out of defensive considerations, how can you not master the means of observing the surrounding environment in this case? ”

"That being said......"

Tian Xian took over and said: "And the actions of the Blood Sect also prove this speculation, he has been in the miscellaneous area for so long, thinking about countermeasures to deal with the current situation, I proved that after the shock came from above, he suddenly returned to the Blood Alliance Hall, I am sure that the means of checking the ground situation depends on something in the Blood Alliance Hall, and it is very likely that it is some kind of instrument." ”

"And!" Tian Xian looked at the waist card in his hand at the light, and smiled very proudly, "We don't need to be further sure, it's enough to know this, the Blood Sect will definitely act according to the plan at that time, I really want to see what kind of expression he will have at that time." ”

"If you can successfully escape this time, even if you completely draw a line with the Blood Alliance. The fourth girl looked at the waist card in her hand, her face full of seriousness.

"Then I will also draw a line with the Blood Alliance, speaking of which, my contact with the Blood Alliance started with you, but I didn't expect it to end with you in the end, it feels really strange." ”

"It's some kind of fate, I guess that's it. The fourth girl smiled and sighed, "But the concubine likes this, and I hope that I can accompany Brother Tian to go farther and longer when the time comes." ”

Tian Xian smiled and nodded, put away the last piece of the waist card, stood up and patted his buttocks, took a deep breath and looked at the top of his head, and determined the time through the leaky roof, "Let's prepare! Let's advance the time half a day and start at night!"

The update is stable these days~ The time is also used very well

Tomorrow weekend will add more properly will not break the promise (to be continued......)
