Yes, this would change the history of mankind, to be able to build with a water hardening material, with raw materials which were easily to obtain, which were simple to prepare, it truly numbered among one of the most efficient tools for tilling the fields.
Roland estimated the needed time, even if he would implement new technology, even with cement he wasn’t sure if it was possible, the amount of cement they actually needed was too big, he wasn’t sure if they could calcine so much cement powder within three months. And concrete toughness would be inferior, in the end they would need to reinforce it with steel, thus the probability to succeed in building a concrete city wall was not that great.
They had to maximize the usage of the existing materials and save cement, so building a fieldstone wall would be the most appropriate choice.
The so-called fieldstone, was a stone which had not undergone any grinding, it was just a natural byproduct of mining. This stone, because of the irregular shape of the edges and corners, there was no way to directly using it to build, instead it first need to be processed by the stonemason into usable bricks. But building a fieldstone wall while using cement as binder was possible, regardless of how oddly shaped the stone was it could be used, the gap between the stones was filled by the cement, saving cement and using leftover materials.
With this the big direction was set, but the actual implementation, he was afraid he would have to do it by himself, thought Roland. Regardless of whether it was the calcined cement or fieldstone wall, both were new things. Except for himself, no one had seen these things, and also no one knew how to make them. He was afraid he would be very busy for the next three months.
“You, look here.”
The sound of Anna’s clear voice came from behind him.
As Roland turned, he saw a small cluster of flames in her palm quietly burning, there was clearly no wind, but the flame tip was rising up and down, as if it would nod to her. She shook her finger, and the fire was like a toddler, moving slowly towards the tip of the finger. In the end, it stood at the top of the index finger, simmering down.
“You did it.”
It was an incredible scene, Roland felt admiration from the bottom of his heart. This was not illusion magic, nor a chemical trick, but it really was a supernatural power. But this was not the most attractive thing to Roland — many time more dazzling than the flame, was Anna’s look.
While she was intently staring at her fingertips, the lake water limpid eyes were reflecting the vibrant flame, as if an elf sealed within a sapphire. The traces left from the prison torture had already faded, though she rarely smiled, but her face was no longer lifeless. On the young lady’s tip of her nose was a speck of sweat, the rosy color on her white checks emitted vitality, even looked at also can let a person feel cheerful mood.
“What happened to you?”
“Ah… Nothing,” Roland noticed he looked at her for too long, he removed his gaze and coughed.” well, then, try using it to melt the iron.”
In the past few days, except for eating and sleeping, she always repeated her practice, in front of the hardworking enthusiast Roland could only endlessly blush in shame — even in the face of the college entrance examination he did not work so hard.
“Apparently she will not need long, until she completely grasps this power,” Roland thought. Following that, his ideas of new projects can be set on the agenda.
Chapter 10 The Stonemason
This week, the weather wasn’t good, the sky was always gray, Karl van Bate’s mood was like the weather, gloomy to the extreme.
Walking on the wet stone street, from time to time there were people greeting him. In in this town, Karl run a school. At Graycastle those noble children with the talent to go to school, attended a different kind of college, here he was also teaching for the children of ordinary people. Therefore, in this border town, he had a very high reputation.
“Hey, Mr. van Bate, good morning.”
“Sir, is my son doing all right?”
“When are you free, Karl, let’s go fishing together.”
At ordinary times Karl would always smile and would respond to them, but today he just nodded, never saying a word.
Since he witnessed the hanging of Anna, in his eyes the world appeared to be flawed — or to say since his departing from Graycastle a crack seems to be rising into existence, but he deliberately turned a blind eye. He used his busy work to numb himself, and to a certain extent, he even used the innocent smile of the students, to cover this crack.
Until Anna died, he thought, that the world had not changed. But after the hanging, the crack not only did not disappear, but it expanded.
Regarding Anna, he recalled the memories of the previous half a year. Within the more than thirty children in her class she stood not out, with a normal appearance, she was never a person of many words, but there was something that let Karl felt a little impressed.
