The old magician stopped his spell, looked down at Gretel, and frowned slightly:
"Why, you are not satisfied with this wall?"
He was vaguely unhappy. Fossils turned into mud, and mud turned into stone. These two brothers were all fifth-level spells of the transformation system. In other words, as long as they were level 9 wizards, they could operate them. However, as a level 14 great magician, he, the review committee
The Lord of the Committee personally took action, and the hardness and fineness of the stone and the precision of the shaping were miles ahead of those mid-level mages.
Why, the little guy still dislikes one thing and the other?
But he saw a head buried motionless, and an open palm. Grete squatted in a ball on the ground, holding forward the casting materials that turned mud into stone - sand, lime, water - the sound
Confused, as if trying desperately to remember something:
"No... I mean, sand, lime, water, isn't this cement? Cement plus gravel and water is concrete...
Different formulas have different functions, some are quick-drying, some are wear-resistant, some are acid- and alkali-resistant, some are high-temperature resistant, and some are particularly frost-resistant, impermeable, and crack-resistant...
You must try this one after another!"
The old magician was silent. He had cast the spell of turning mud into stone countless times over the decades, and indeed it was slightly different every time. Moreover, this difference did not seem to have anything to do with his spell control. He couldn't bear it.
Squatting down and looking into Gretel's eyes, he asked:
"Cement? Mix..."
The words got stuck here. After thinking for a while, I awkwardly repeated the word I heard for the first time:
"Concrete? What is that? Do you know the recipe?"
"I don't know!" Gretel said very confidently:
"I am a healer! I know that sand, lime, and water can be mixed together to make cement. Oh no, it seems that clay and lime can be burned into cement at high temperatures. Cement plus sand, water, gravel, etc.
Yes, it can be made into concrete! It doesn’t require extraordinary strength, ordinary people can also make it!
But which formula produces what result? Then, I have to try them one by one... I know that there are several types of cement. It seems that it is burnt with lime, burnt with sand, and burnt with alumina... volcanic ash,
Everything is made from fly ash and slag..."
His voice became softer as he spoke later, and he shrank down, almost curling up into a ball. He himself felt that this method of "I know the direction, but you have to try the details" was really a bit irresponsible...
The problem is that he really doesn’t know!
He majored in medicine, not architecture or materials science! The difference between cement and concrete was something he heard from the workers on the construction site when the hospital was building a new building!
If you ask him to give you the formula, the proportions of different formulas and different properties of cement, you can't do it even if you kill his head!
The old magician wanted to complain about Gretel. However, before he could say anything, he heard from behind him that Old Sam was complaining softly to others:
"This kid is here again..."
Ah, yes, it was the same last time when mithril was smelted. To give you a direction, a group of great magicians and their disciples and hundreds of people tried to do it day and night. This little guy turned around and went to other things, tossing.
After finishing the disinfectant, we also produced plague seeds in the laboratory...
So, if you are harming the Perfection School, are you here to harm their Transformation School?
What's even more irritating is that old Grom, the necromancer, is still showing off cynically: "Little Gretel never gives us things like this... He always makes them completely before submitting them.
I have never thought of using us as tools..."
...Is he treating you well?
That’s because I’m afraid you’ll get into trouble!
Plague is a thing that spreads throughout the city if a spy gets a little bit of it. If you start playing around with it regardless of the severity, might the whole city be wiped out?
The old magician really wanted to stand up and beat that guy up. Oh, by the way, here in Gretel, you can't hit him, and you should knock his brains out. But the little guy's eyes are very sincere:
"I think it would be more convenient to cast the spell if the casting material was changed to cement, or cement, sand, or gravel?
Cement with different formulas and labels can be prepared in advance to facilitate control of the concrete type when casting?
Also, the compressive strength of concrete is high, but the tensile strength is not high. If you add steel bars into the wall, the reinforced concrete will be stronger... Or when you build the building, you can add steel bars as casting materials and try it out to see the effect...
…”
"Do you still want the Mage Tower!!!" The veins on the old magician's forehead were twitching. He had to try this and that. After so many experiments, several years had passed. "The foundation wall of the Mage Tower
, it’s up to you to decide which kind of stone you want!”
"Hey, hey, don't bully our kids." Old Sam suddenly came over and stood in front of him:
"Isn't it good that I have a research direction for you? If you are not interested, Thunder Horn will take it back and study it yourself. It's not like we don't have high-level mages! If you come up with something later, you have to pay for it!"
"No, no, no!" the old man said anxiously:
"Why are you doing this in the plasticity department? This is not your strength! Leave it to us, we will study it and give him a share later!
——Little Gretel, what proportion do you want?"
Grete gave him a confused look, stood up decisively, and stood next to old Sam.
I don’t know, you just have to figure it out. Anyway, we have a high-level mage in Thunder Horn, you can’t cheat me...
Old magician: "..."
Old Sam:→_→
Are you using me as a negotiating tool?
In any case, the construction of the mage tower that Gretel has longed for has begun step by step. Gretel is indeed curious about various cement materials, but ten birds in the forest are worth one bird in hand. It is more important to get his mage tower as soon as possible.
The worst thing is, wait for the School of Change to experiment with new materials, and then ask them to modify it...
Anyway, new cement and new magic also have their own share, right?
The review committee member of the Change Department was just happy to see Xun Xin, and he cast a spell to build two stone walls. To really build the mage tower, he would have to rely on the construction team of the council. They have a magic circle and a lot of casting materials. The most important thing is,
There are drawings——
Grete stood next to the foundation, watching the four high-level mages open the magic circle, compare the drawings, and jointly cast spells. After a lengthy spell, a large earth elemental stood up in the magic circle, uh, or
It is said to be a stone element. After all, it is smooth, dense, and slightly reflective. It looks very much like a high-end stone.
The stone man squatted down and huddled up, as if listening to the magicians' explanations and descriptions. After listening for a long time, he walked out of the magic circle and jumped into the foundation pit. Gretel couldn't help but blurt out:
"Why--"
Such a big stone man, please don't destroy my foundation!
Miraculously, this stone man, which was three people tall and weighed at least seven or eight tons, made no movement at all when it jumped down, as if it had merged with the foundation silently. The four high-level mages spoke more urgently and chanted incantations.
After a long pause, they suddenly raised their arms at the same time:
"rise--"
Smooth, dense, and dark walls rise from the ground, getting taller and longer.
This tower is a common style for mage towers, with an octagonal tower body, three floors underground and nine floors above ground - because it is a high-level mage tower, the number of floors has been specially added. The tower is thicker at the bottom and thinner at the top, and the outer walls are slightly thinner.
It tilts inward, but the amplitude of the tilt is not large. The bottom floor of the mage tower has a radius reduced by 20% compared to the top floor.
The height of the mage tower is quite high. Unlike the residential buildings Gretel saw in his previous life, the floor height is 2.8 meters, and the clear height of the living room is 2.4 meters. The mages like an open environment, so every floor of this mage tower has
It is more than 3.5 meters, and including the thickness of the ceiling, it is almost four meters.
The nine-story tower rose straight from the ground. Grete stood on the edge and looked up, his eyes rising as the tower kept getting higher and higher...
"Oops!" He raised his head too much and almost lost his balance!
The eight-sided tower has three windows on each side. Of course, from the second floor to the fourth floor, which is the ground part of the P4 laboratory, there are no windows in the red zone. Not only are there no windows, the entire wall is tightly sealed
Really, there is no gap to the outside world.
The outer wall reached the highest point and retracted inward to form a pointed sloping roof. There were also a few bells hung under the eight eaves. Grete once thought of making hollow eaves on each floor and then surrounding the tower.
A circle of balconies and railings were severely rejected by the magician in charge of the project:
"What does it look like! The Mage Tower has never been like this! Do you think the Magic Tower is too safe and you want to provide a place for thieves to climb the wall and catch them?"
Uh... Actually, what I'm thinking of is Chinese-style buildings like the Yellow Crane Tower and the Six Harmonies Pagoda...
Gretel was stunned and stopped talking. Thinking again about the theft in the laboratory, maybe if he really followed this plan, he would install security windows on every floor?
That visual effect is terrifying just thinking about it.
Professional magicians worked together to cast spells, and the construction speed was incredibly fast. For a building with three underground floors and nine floors above ground, from the time the foundation was laid to the capping of the structure, it would have taken at least three months in Gretel's previous life - every three floors underground.
The first layer takes at least half a month, and each layer takes 5 days after positive and negative zero. The top layer is slower, about ten days.
However, in just about two hours now, the outer walls and roof of the Mage Tower have been formed. Gretel waited next to it for another hour, and the four magicians stopped casting spells and breathed a long sigh of relief. On the walls of the Mage Tower, smooth
On the bulge, the outline of a stone elemental person emerged, gradually separated, and jumped out.
When he stood in front of everyone, he had shrunk by half the size he had just appeared.
"Okay, it's fine inside." At this time, most of the judges had dispersed, and only the old magician of the transformation department was still standing there, accompanying Gretel as he looked at the wizard tower. Seeing the stone element appear, he pointed at the tower.
, smiled at Grete and said:
"The rooms, floors, stairs, etc. have been built. The element pool, magic defense, etc. are about the protection system and the conjuration system. We have to wait for a few more days. What do you think, do you want to go in and take a look first? Not satisfied.
If so, you can still adjust it now——"
In half a day, he completed the work that took several months in his previous life... Regardless of production costs, mages are worthy of being the number one productive force...
