Release that Witch

He had decided to stop the demonic beasts at the Border town – joining the elite soldier with the town guards, he would also intensive the farming by expanding the area the guards patrolled. If he wanted to build the wall, connecting the north slope of the mountain and the Chishui River within three months, he must use an appropriate technology from the modern times.

It was not the case that Roland had suddenly thought of this, previously he had checked the edges of the Border town (although he didn’t go personally), in his memory remained a clear picture — the northern slope of the mountain and the Chishui River were only separated by 600 yards at their closest point, it was a natural bottleneck. And due to the all year round mining in the North Mine, it was surrounded by rock gravel mined from the cave.

These gravel cast offs were ash gray, containing plenty of calcium carbonates, which could be used as limestone after grinding. With the limestone he had his solution, it would be equal to cement.

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.
