Yan Liu's eyes lit up suddenly, and then he said seriously: "Yes, I think it may be that the Ninety-Nine Lord is afraid that we will be too tired to walk more than 100 meters underground, so they deliberately moved this place here, and made a corridor to the ground to facilitate our rescue."

The reason why Yan Liu mentioned the corridor here is because the corridor created by Ninety-Nine is far superior to the underground hall in terms of the smoothness of the walls and the fineness of the stairs. Even the buttresses in the hall are not as fine as the 'doors' created by the ninety-nine.

And Li Mo can also see this, and Li Mo is also in the mouth of several architectural magic experts, and it has been double-confirmed.

"Oh...... Is that really the case?" Li Mo nodded first, his eyes drooping slightly, as if he was thinking about something.

Originally, the time of ninety-nine to save people was enough to make Li Mo unbelievable. And not only saved people, but also prepared such a beautiful corridor for them ordinary Red Devils.

And now, there is one more: the original height of the underground space has been raised.

For a while, Li Mo didn't know how to thank Ninety-Nine. Because "If what Yan Liu said is true, in that case, wouldn't Sister Xiao Jiu... Too sensible, isn't it..."

And just as he realized that Ninety-Nine was sensible, his brows tightened suddenly. At this moment, Li Mo suddenly remembered that the day before yesterday, after Xiao Jiu returned to the guild, he said to Xiao Jiu, "Hmph, I'm back so soon, don't tell me that I just went to buy a dress." After that, Xiao Jiu suddenly cried. (2-100)

"Ah...... That's why at that time, would it be like that......" Li Mo felt a little guilty in his heart. Comparing hearts to hearts, a princess of the Nightless Clan with such a high level prepared so much for them, the Red Devil Clan, who had a very low level, but when she returned to the guild, she was ridiculed......

"Hey...... It's a bit of a stretch. Li Mo was silent for a moment.

And while Li Mo was thinking, Yan Liu was already preparing to strengthen himself with strengthening magic and reinstall the stone pillar that had just been removed.

Just as Yan Liu had just put on two layers of special effects and was about to bend down to lift the stone pillar, Li Mo suddenly continued, "Then, Brother Xian, can you tell my brother about me, how did you find out about this?"

"Forehead ......" Yan Liu's heart jumped, knock. His hands were removed from the pillar and he straightened up, ready to answer.

At present, Li Mo's words have two meanings for Yan Liu:

1. What kind of magic did you use to discover that this underground space was originally in a deeper place?

2. How did you come up with this before you used magic to determine this?

Because I am not sure what it means, and because the second one is difficult to answer. So Yan Liu chose to answer in the first way: "Use restoration magic to restore the soil layer in this wall."

As he spoke, Yan Liu gently tapped the wall with the back of his fist. Then he was ready to grab the stone pillars on the ground and stuff them back in.

"Huh." Li Mo's eyes lit up, his handsome eyebrows raised, and he immediately understood what Yan Liu meant.

After all, Li Mo is also the son of the city lord, and he received a good education when he was a child. He still understands the common sense that 'restoration magic can be used to measure distances'. Although he didn't use restoration magic, he learned from his mentor that some professional architectural mages could measure it through restoration magic. For example, by tearing a piece of paper in two and attaching it to both sides of the object to be measured, an experienced architectural mage can quickly know the approximate or precise length through mid-level restoration magic.

"That, Brother Xian, you can put that pillar here first. I'll send someone to restore it in a moment, and those architects over there happen to be here, so I'll just hand it over to them."

"However, if you don't make up for it in time, what if you bear the load?" Yan Liu looked at Li Mo and said a little nervously.

"It's okay," Li Mo smiled, "This is not the main load-bearing place, don't worry." As he spoke, Li Mo raised his hand and applied a layer of solidification magic on the part of the wall that was being cut.

"Well, thank you, Lord Viscount. I'll go back first."

After a little greeting, Yan Liu turned around and left, and Li Mo also gave him a gentle ride.

After sending Yan Liu away, Li Mo returned to the bottom from the ground. There are two fundamental reasons why he didn't let Yan Liu repair, one is that this kind of restoration work is handed over to a professional architectural magician to do it more beautifully, and the second is that Li Mo wants to know the exact value of the rise of this underground space.

The architects, who had been planning the warehouse, were invited by Li Mo to measure the distance of the wall cut by Yanliu, and soon got an accurate result: "75 meters."

When he learned that the soil drop had reached 75, Li Mo, the rangefinder engineer, and the soldiers around him all showed shocked expressions.

Especially the soldiers who gathered around the door were even more surprised.

"What?! Seven, seventy-five meters?" 「75！？」 Some of the soldiers stuttered and lost their voices in astonishment. Because for the Red Devils, it would take at least a month to move such a large-scale building and such a long distance, and it would take 10 people a day to work in shifts for a month. (with earth elemental magic)

But in reality?! The speed of ninety-nine saving people has long been spread throughout the city - 'all the girls will come out in half an hour'

What a gap!

Li Mo squinted his eyes slightly, although he didn't doubt Yan Liu's words, he never expected to move 75 meters.

It is important to know that moving an underground structure requires a lot of mana, and the mana consumed is proportional to the size of the building and the time consumed.

How much time does it take for ninety-nine to save people? Saved all the girls in a few dozen minutes, and also applied magic clothes to those girls, and moved the space by the way. How much mana does it take?

"Master Qian, are you sure?" Li Mo asked respectfully.

The architect had now asked his assistant to help put the stone pillar back in preparation for restoration. He turned his head to look at Li Mo, "Lord Viscount, why am I lying to you about this kind of thing? It's really 75 meters, and even if there is, the error can't exceed five centimeters. And, if I'm not mistaken, it's likely that this underground space was moved up with spatial transfer magic, not by earth elemental geology. Lord Viscount, if you are interested, you can check with Ninety-Nine."

Li Mo didn't answer, just nodded and smiled slightly.

The architectural mage didn't seem to finish speaking, he frowned and smiled at Li Mo, and stared at Li Mo with slightly old and wise eyes: "Lord Viscount, although from a racial point of view, I shouldn't say such things, I really feel that we should ...... Cherish a little."

"yes, I understand." Li Mo nodded understandingly. After a few more words, he returned to the ground.
