Chapter 12 Building High Walls
The next day, in the Dongfang mansion, Dongfang Haotian called carpenters, masons, stonemasons and other craftsmen from the whole town to gather, and he planned to build a city wall for Qingfeng Town.

Generally, towns exist without walls.

The main reason is that the cost of building the city wall is too high. For a small town, it is not cost-effective, and there is not enough financial resources to build it.

However, since he decided to use Qingfeng Town as his first base, it was naturally impossible without the protection of the city wall.

Dongfang Haotian not only needs to be built, but also has to build an extremely tall and majestic city wall to protect the entire town.

Although this is a world of martial arts, considering the current level of force in Qingyang Mansion, the protective effect of the city wall is still very large. Even the top real martial arts masters cannot easily break through the city wall.

The entire Qingyang Mansion is likely to be in turmoil, and the construction of the city wall is a very necessary thing at present.

Dongfang Haotian's plan is to use the current area of ​​Qingfeng Town as the inner city, and then expand it by 2 kilometers from east to west and 1.5 kilometers from north to south, forming a city that can accommodate nearly 10 people.

Of course, the first step is to build a city wall that encloses the current Qingfeng Town.

The wall of the outer city can only be implemented after there is enough energy and financial resources.

"Back to Young Master Dongfang, building the city wall requires a lot of money and manpower. Do you really want to build it?" The craftsmen reconfirmed.

After all, it's not a small investment.

"En." Dongfang Haotian nodded in confirmation.

Then he said: "However, this time I don't plan to use stone to build the city wall, but to use a brand new material to build the city wall."

The city walls of this different world are all made of selected stone materials, polished and built.

It is not only a waste of time to collect and transport qualified stone materials, but also the transportation cost is very high. It needs to go deep into the mountains and forests to search everywhere, and the manpower used is huge.

Therefore, Dongfang Haotian intends to use other methods to build the city wall.

Anyway, as a modern person, he has some knowledge of modern people.

He was going to burn blue bricks to build the city wall.

The advantages of green bricks are strong air permeability, good water absorption, maintain air humidity, wear resistance, and not rot for thousands of years.

At the same time, the blue bricks give people an elegant, calm, simple and peaceful aesthetic feeling, which is in line with a deep artistic conception.

In addition, clay, the material for firing blue bricks, is everywhere in Qingfeng Town. It is very convenient to obtain materials locally, which greatly saves transportation time and cost, and the labor force will also be greatly reduced.

It can also be continuously fired without worrying about the shortage of materials and the inability to complete the city wall.

As for the firing method, I learned from the books I read at the time. It is roughly mixed with clay and water, extruded, then baked in a brick kiln to about [-] degrees, and then cooled with water.

So he wrote down the firing method and recorded it in "Blue Brick Firing Method".

At the same time, they also wrote a vaguely outlined "Brick Kiln Construction Method", asking them to build a brick kiln that can raise the temperature to [-] degrees to burn green bricks.

Of course, he was talking on paper, and he had never personally operated it.

But with the general method and steps, don't underestimate the IQ of these people from other worlds. After many times of practice, they will definitely succeed.

All the craftsmen flipped through the "Green Brick Firing Method" and "Brick Kiln Construction Method", and began to discuss in whispers.

After about a stick of incense, a gray-haired craftsman asked:

"Master Dongfang, is the function of the brick kiln to increase the heat of the fire to a thousand degrees in your mouth?"

Dongfang Haotian thought for a moment, but he didn't know the specific situation, so he could only vaguely answer: "It should be like this."

The old craftsman said: "I think building a brick kiln is too troublesome. I know a blacksmith in Xiwang Village. He found a ground fire. The heat is extremely high. I don't know if it can reach the so-called [-] degrees in your mouth."

Degrees are measured on Earth, so people from other worlds naturally don't know what a thousand degrees means.

Dongfang Haotian asked: "Can iron be melted into molten iron?"

"Yes." The old craftsman nodded.

"Alright, the temperature of the ground fire here is over a thousand degrees. You can try it and use it to burn green bricks."

The melting point of iron is about 1500°, and it can melt iron, which naturally exceeds a thousand degrees.

As for whether it will work in the end, Dongfang Haotian is not sure.

"Then, let's take our leave and immediately try to make the green bricks that Young Master Dongfang mentioned. If it's really so magical, it's a great invention." All the craftsmen exclaimed and said goodbye.

"Go ahead, report to me anytime you have any progress." Dongfang Haotian nodded.

……

Three days later, the old craftsman sent a simple and simple blue brick from Xiwang Village overnight, and placed it in front of Dongfang Haotian.

Dongfang Haotian's eyes lit up, and he didn't expect that the group of craftsmen would actually make it.

"Master Dongfang, this old man is also amazed that a pile of ordinary dirt can turn into such a miraculous thing. The young master is really extremely intelligent and admirable." The old craftsman praised.

Dongfang Haotian slammed his hands hard, but the blue brick didn't move at all, and it didn't break in two.

This shocked him unceasingly. He never expected that the green bricks fired would be so strong. "My good guy, it's so strong."

On Earth, some trained ordinary people can split green bricks with bare hands.

Although Dongfang Haotian only used 3000% of his strength, but now he is at the ninth level of body training, and can produce a huge force of more than [-] catties when he bursts out with all his strength.

"I'm just trying to see how tough you really are." Dongfang Haotian secretly said.

Then he continued to increase his strength until he used more than six layers of strength before breaking the green brick into two pieces.

Dongfang Haotian gasped. How terrifying would the defense of the city wall built with such hard green bricks be?
So he asked in amazement: "What's going on? Why is the hardness of the blue brick so strong."

The old craftsman smiled and said, "Young Master Dongfang, are you shocked by the hardness of the blue bricks? Back then, the old man and others were also surprised by its sturdiness."

"We all guess that it has something to do with the ground fire we used."

"Earth fire? Is it the heaven and earth fire mentioned in the book?"

Dongfang Haotian has also heard in books that some magical fires between heaven and earth have incredible energy.

If this ground fire is really a magical fire between heaven and earth, it is also very reasonable to increase the hardness of the blue bricks.

This is a treasure, and people will be sent to protect it closely.

"By the way, what's your name." Dongfang Haotian asked.

"Back to Master Dongfang, this old man's surname is Zhou, and his name is Renfa."

"Well, from now on, Craftsman Zhou, you will be the owner of the Xiwang Brick Factory. You will be fully responsible for the firing of blue bricks and the construction of the city wall, and you will receive one tael of silver every month."

Craftsman Zhou thanked excitedly: "Thank you for cultivating, young master, I will definitely not let you down."

He is just an ordinary and humble craftsman, and he never thought that he would be reused one day, so the excitement in his heart can be imagined.

"I also have a copy of "Lime Mortar Preparation Method" here. You can find some lime, sand, and water, and mix them according to the ratio above to stick the green bricks."

Dongfang Haotian handed a note to Craftsman Zhou.

"Yes, sir."
