This is the third underground stronghold we've seen. Mu Xuanyi walked in the deep dark aisle and muttered quietly.

"They all like to keep their strongholds underground anyway. Xiao Lin said softly, he was actually a little puzzled, it wasn't necessarily safe to put it underground, after all, there were too many people who liked this now, if he heard about the secret room, the big guy's subconscious reaction was underneath, then this secret room wouldn't be useless at all.

"The same cannot be said. Liu Shan explained, "It's just that they all happened to be built underground." ”

"Yes. Xiao Lin pouted and said, how did he remember that the branch and headquarters of the Black Court were all built underground, and some were still under the lake, and it was said that the headquarters of the military department was deep in a mountain, of course, he had never been there, so he couldn't be sure.

However, if you think about it carefully, the underground is indeed the most suitable place, which will not be exposed to the enemy at the first time, and at the same time, it can also avoid the public's sight and prevent it from being watched and probed by the people from time to time.

"I have seen strongholds set up in heaven. Sukh suddenly joined the conversation, they were now heading towards the place where the change had occurred, and they were idle along the way, so it was better to talk for a while.

"Heavenly?" Xiao Lin and several people were stunned, "Is it the same as a floating island?" "They have seen many floating islands in the Tianxiang Imperial Capital, those are places where high-level and nobles live, floating in the sky for many years, they can have a panoramic view of the scenery below the imperial capital, and at the same time, it also invisibly shows a kind of class identity, and the people below are just ordinary people, and the princes and nobles in the sky are the princes and nobles.

"That's pretty much what it means, except that the air stronghold is even more magical. "It is a secret stronghold that is completely hidden in the clouds, and it is impossible for ordinary people to see the true body of that stronghold even if they look up on the Internet." ”

"Really?" Xiao Lin said with some suspicion, "The clouds are all floating, sometimes there are no clouds, where to hide in that place?"

"Well. Sukh rolled his eyes, and was about to continue, when the griffin suddenly coughed dryly.

"Ahem, we're almost there. The griffin said lightly, and glanced at Suhe with a warning look, as if he was a little complaining that this man's mouth was so loose, if he hadn't stopped it all in a mouth.

Suhe patted his head and smiled at the griffin: "Oops, I almost said it, my fault, let's keep going." ”

"What, the interest has been hooked, and the result is not to be said. Mu Xuan rolled his eyes and said, as if he was very dissatisfied with Su He's halfway up and shut up.

Mr. Wan, who was at the forefront, also sighed in his heart, he had been listening with his ears pricked up before, after all, it was the first time he had heard of the mysterious stronghold hidden in the sky, and he wanted to know how it was done, after all, although the Wanbao Chamber of Commerce had money, it was difficult to match the four empires in the use of some technology and superb means.

"It's not far ahead. The capable man at the front whispered, "Please be careful, because powerful energy fluctuations have been heard in the distance. His gaze swept over Xiao Lin and the others, and the implication was obvious, if these dolls were not fully protected, they were likely to be injured by that energy.

"Don't worry. Su He chuckled and said, although he didn't say much, but the self-trust revealed in his words could be felt by anyone, "You guys follow me, don't run away." His last sentence was said to Xiao Lin and a few people, these dolls sometimes don't play cards according to common sense, and they may take action on their own if they are not careful, and if they don't take care of it in advance, he is really afraid that these children will mess around.

Xiao Lin and the others silently followed behind Su He, their eyes kept looking into the depths of the aisle, they were now in a deep underground, in this dark underground space, there were countless tunnels crisscrossing and crisscrossing, weaving a complex network of tunnels, if it wasn't for people who had lived here for a long time, it was estimated that they would soon lose their way if they broke in.

And at this moment, in the depths of the tunnel where Xiao Lin and the others were, there were flashes of light, and at the same time, there was a low sound that sounded rhythmically, and everyone involuntarily accelerated their pace, and soon came to the end of the aisle, which was a pitch-black wall, but at this moment, the wall would be lit up every once in a while.

"No way?" Sukh muttered softly.

"Yes. The capable man who led the way nodded and said, "When we mined this vein before, we did a detailed inspection, and the soil in front of us is no longer suitable for further excavation, otherwise it is likely to cause collapse." ”

"I see. Suhe nodded, pressed his palm lightly against the pitch-black wall at the end of the tunnel, closed his eyes and began to feel the energy fluctuations coming from the back of the wall.

"It's not far from us. Suhe whispered as he sensed, "And this energy fluctuation is very regular, not like what an ability person can have." ”

"Why?" Xiao Lin asked softly.

"Because the power of the ability is controlled by itself, no matter how fine your control of the power is, it is impossible to achieve the same intensity every breath released, it will always show a state of fluctuation. "But the intensity of this energy is maintained at the same level every time, so it is absolutely impossible for the capable person to release the breath, but more like a ......."

"Circle. Su He said lightly, "Our neighbor has set up a powerful magic circle next door, but this ore vein is far away from the City Lord's Mansion, but it is so close to each other in the underground space, which means that the scope of the people's underground stronghold may be larger than this ore vein." ”

"It's not a year or two to build such a huge underground space. The griffin whispered, "The other party probably spent a lot of effort." ”

"That means that the other party has been controlling that beast for a long time. Lin Yin'er said with some concern.

"The opposite may be true. Su He muttered, "The other party may have not been able to grasp the power of that strange beast, which is why he will make such a big move in the auction, if it had been successful a long time ago, it would not be like this." ”

"Agreed. The griffon nodded, "So if we break through now, we have a good chance of disrupting the other party's actions, after all, we have sensed their movements, but they may not have noticed us." ”

"You can't be reckless. Su He shook his head, he was very cautious, "Looking down on the power of the City Lord's Mansion will suffer a big loss, we must be prepared that the other party already knows where we are, and we have asked for reinforcements, but there is no feedback yet, it is more appropriate to wait and see what happens at this time, and Jian Ji's side still needs time to prepare." ”

"It's the same here at the Chamber of Commerce. Mr. Wan added, "Our capable forces have been scattered all over the place, and it will take time to assemble now, so it is really not appropriate to attack at this time." ”

"How long will it take for the Chamber of Commerce to assemble troops?" asked Suhe, looking at Mr. Wan.

Mr. Wan smiled bitterly: "You must know that we are a chamber of commerce, not an army after all, if we want to gather a part of it, it can be completed quickly, but if we want to gather all the capable people in the area of Chaos City, it is estimated that it will take three days." ”

"So long?" Su He frowned, this efficiency was a bit beyond his expectations, it was too slow, you must know that he was from the Tianxiang Empire, the imperial army could be assembled in a very short time, and it could be put into battle at any time, but the Wanbao Chamber of Commerce took three days, which gave him a headache.

"What now?" Liu Shan asked softly, his tone sounding a little heavy, the longer the time dragged on, the more unfavorable it would be for them, but if they rushed over with their current manpower, it was estimated that they would not do much, and they might fall into a situation of being besieged.

"Think long-term. Su He sighed, although he really wanted to rush over at this time, but it was not a good thing to attack rashly, and although there was a dark stone wall separating it, he could clearly feel that the distance between the two tunnels would not be too far, in fact, as long as he dug a little further ahead, he could connect with the underground passage of the City Lord's Mansion.

Such a short distance, Su He didn't think that the other party would not be unaware, he estimated that the City Lord's Mansion might have been completely prepared, waiting for them to rush over recklessly, and then step into their trap, at this time recklessness will not have a good result, it is better to be careful, wait until the order auction arrives, the Wanbao Chamber of Commerce has been assembled, plus the news of reinforcements from the two empires of Tianxiang and Longxin, and then it will be better to launch a general attack, and the possibility of success will be greater, at this time what they need to do is to be patient.

"You keep an eye on this place and report to me as soon as there is any trouble. Mr. Wan instructed the capable man, "In addition, start building a defensive circle here, the stronger the better, don't let the other party take the opportunity to break through, this vein is very important, and there is no room for loss." ”

"Yes!" the capable man replied, and immediately flew into the distance, and began to call for more helpers to come here to set up a magic circle and make fortifications.

"Let's go out first. Sukh said softly, "It looks like it will take a little time to greet our neighbors, so let's discuss the specific attack plan at this time." ”

Xiao Lin and the others naturally had no opinion, the griffin and Mr. Wan also agreed with Su He's opinion, it is always right to be cautious, and the group turned around and walked towards the height of the ore vein, but everyone's face was a little heavy, the city lord's mansion had obviously built that stronghold into a solid place, and it was not so easy to break in, and it was estimated that there would be a bloody storm and a fierce battle.

Su He glanced at Xiao Lin and the others, a wry smile appeared on the corner of his mouth, and he muttered softly in his heart, "I don't know if these few will leave a psychological shadow at that time." Of course, this matter is not under his control, he can only pray that Xiao Lin and the others can get through it and not be crushed by that tragic scene.
