Tianqi looked at Zhou De's appearance, and felt a burst of amusement in his heart, and said to Zhao Lao with a smile: "Zhao Lao, when I came, I saw that the people of our gang were digging a ditch, was that what you arranged?"

"Well, yes, I made them dig those ditches. Pen "Fun" Pavilion www.biquge.info," Zhao Lao nodded and said.

"What are those ditches for?" Tianqi said the doubts in her heart.

"Come in with me, let's go inside. Zhao Lao said with a smile.

"Well, that's fine. Tianqi nodded, and then the four of them followed Zhao Lao into the wall.

Connecting the wall door is a narrow road, this road is not wide, but it is very long, after walking for a while, Tianqi was surprised to find that they have been walking in a straight line, if calculated according to the length of the wall, according to the speed of their travel, they should have passed through the wall by now, but now they can't see the end of the road.

After walking a distance of more than ten meters in this corridor, Zhao Lao suddenly stopped.

"Old Zhao, what's wrong?" Tianqi asked suspiciously.

"Here we are. Zhao Lao said with a smile.

Then Tianqi saw Zhao Lao walk to the wall of the corridor, put his palm on a piece of bluestone on the stone wall, and then pressed it gently.

"Click!" there was a thud from the sunken bluestone, and then a sound of mechanical movement came from behind the stone wall.

Then, under the surprised gaze of Tianqi and the others, a stone door was opened on the originally flat wall, and a trace of light came out of the stone door.

"Please come in, this is the core area of Xuantian Gate. Zhao Lao pointed to the door and said.

At this time, Tianqi had a lot of doubts in his heart, but he knew that now was not the time to ask, so he raised his legs and walked into the stone gate.

Entering the stone gate, Tianqi was immediately shocked by the scene inside the door, and saw that there was a huge space inside the door, and there were many things placed in this space, like a laboratory, and Zhao Lao's apprentices were constantly fiddling with those tables, as if they were doing some experiment.

This space is about ten meters high, Tianqi raised his head, and saw that above their heads, large and small gears were slowly turning, these scenes were like science fiction.

"Old Zhao, this ......" Tianqi really didn't know how to describe his current mood.

Zhao Lao also knew that Tianqi had a lot of doubts in his heart at this time, and he didn't sell it, and said with a smile: "The location we are in now is the center of the Xuantian Tower, oh, by the way, this Xuantian Tower is the name I gave to this building, I don't know if the helper is still satisfied?"

"Satisfied, satisfied!" Tianqi's gaze was still on the surrounding machinery, and he hurriedly replied when he heard Zhao Lao's inquiry.

"Well, maybe you've already noticed that the space we are in is much larger than it looks from the outside, and that's because I've used a bit of spatial power here. ”

"The power of space?!Isn't that the power that only the mellow realm possesses??, are you ......," Tianqi said in surprise.

Zhao Lao shook his head slightly after listening, and said: "I am still not a small distance from that realm, this space power must be exerted by people in the mellow and free realm, there are some special ores in these things that also have this kind of power, these ores have a unified name, called space stones, and most of the tricks you use are made of space stones." Zhao Lao explained.

Tianqi nodded after hearing this, and after thinking for a while, he felt that Zhao Lao's words were very reasonable, if someone who had to be mellow and comfortable could use the power of space, then the value of this bag would definitely be very expensive.

"Including the corridor we walked when we came, it also uses the power of space, if outsiders don't know about this entrance, they will always wander in that space, and then be killed by the mechanism in the corridor, because that corridor is the only way to enter here, so we must be very careful, because I have limited materials in my hands now, so this place still looks a little shabby. ”

"I feel like it's pretty good now, this Xuantian Pagoda is so impregnable, no one should want to come in. Tianqi said with a sigh after hearing this.

But when Tianqi said this, he saw Zhao Lao shaking his head slightly.

"Old Zhao, is there anything wrong?" Tianqi asked suspiciously.

"Although this Xuantian Pagoda is arranged with many mechanisms, and these stones are also high-quality materials, but at most it can resist the attacks of the ever-changing realm, if it is a mellow and free master, it can collapse this place with a light palm. Zhao Lao stroked the bluestone wall and said.

"Uh......" Tianqi was also speechless for a while after hearing this, that level is still a legendary existence in his impression, if it is really that level to attack Xuantianmen, with the current strength of Tianqi and others, it is estimated that they don't even want to touch the corners of the other party's clothes.

"Elder Zhao, our Xuantianmen should not be an enemy of a master of that level for the time being. Tianqi wiped a cold sweat and said.

But Zhao Lao still shook his head and continued: "The world is unpredictable, this place is not only the residence of your Xuantianmen, but also the place where my old bones will retire in the future, so I must try to make it as perfect as possible, fortunately, this Lancheng is also a big land, and I have already filmed our apprentices to find more suitable building materials." ”

"Well, if we find mineral deposits, our Xuantianmen will definitely fully cooperate with the mining. Tianqi said.

"Hmm. Zhao Lao nodded, and then said, "Come with me, let's go inside." ”

Then Tianqi and the others followed Zhao Lao to the central area of this space.

In the center of this space is placed a huge round table, Tianqi approached only to find that the table top of this table is actually carved with dense patterns, after a closer look, Tianqi was slightly stunned, these patterns combined turned out to be a huge map.

"Old Zhao, this is ......" Tianqi seemed to have guessed something, but he was a little sure, so he asked Zhao Lao.

"Hehe, this is the future planning map of the Xuantian Station!" Zhao Lao said with a smile looking at the patterns on the table.

"This ...... This project is too big, isn't it?!" Tianqi said in disbelief, because Tianqi took a cursory look and found that the planned area on this map was several times larger than Lancheng!

"Of course, this project is big, because this drawing was originally intended to be used to build the new capital of Huaxia Domain. ”

From Zhao Lao's mouth, there was a piece of news that made Tianqi a little suffocated, and the drawing in front of him turned out to be used to build the capital!
