"Knock! knock......"

On a high mountain, the sound of crisp percussion continued to sound one after another.

This is the place where Lin Luo chose to build the city.

Standing on the hill, you can clearly see the wide river not far away.

and, looming in the distance, the island of the giant turtle tribe.

At this moment, Lin Luo was standing halfway up the mountain, looking at many busy figures, sweating like rain digging the rocks on the mountain.

The hard limestone was carved into flat strips of stone and transported down the mountain.

Each of those stones weighed hundreds of catties and would be used as the main building material for the construction of the city wall.

This primordial world is different from the earth, whether it is a totem warrior or a fierce beast, it has great power.

Therefore, from the very beginning, Lin Luo did not plan to use blue bricks to build the city wall like the cities on the earth.

Instead, it was prepared to replace the bricks with hard stones, so that the walls would be stronger.

As for the broken stones produced during the excavation, Lin Luo did not waste them, and specially asked some clansmen to collect them and transport them to the bottom of the mountain together.

When I inspected the mountain, I saw that the work of digging the stone was going on in an intense and orderly manner.

Lin Luo didn't stay here for long, and quickly turned around and walked down the mountain.

At this moment, the bottom of the mountain is also in full swing.

In order to complete the construction of the city as soon as possible, Lin Luo not only transferred all the young and strong laborers of the tribal alliance from Zhushan.

At the same time, a large number of women and older children were also transferred to take charge of some of the work they could.

Today, the total number of laborers working on the construction site of the city is more than 6,000, accounting for more than half of the total population of the tribal alliance.

Now there are only a few totem warriors who are responsible for protecting the children, except for the children and the elderly.

"Knock! knock......"

After Lin Luo came to the construction site of the city, the sound of percussion came into his ears again.

However, unlike on the mountain, the sound of percussion on the construction site is very dull.

It was the totem warriors who were smashing the ground with heavy stones.

The walls are not ordinary houses, and they must be built with the foundation in mind.

What if you wait until it's built? If the foundation is sinking because the foundation is not laid? That's a problem.

So, before the official start of building the city walls? Lin Luo first ordered the totem warriors to smash the ground with boulders? Strive to lay the most solid foundation.

And on the periphery of the foundations of the city walls, the excavation of the moat has already begun.

Lin Luo will work this directly? Full authority was given to the Mole Clan.

After all, they're experts when it comes to digging into the ground.

For this? The Mole Clan is not only the whole clan dispatched? Even the Molespirit himself went down.

Let the excavation of the moat progress faster than Lin Luo imagined.

The excavated soil has been piled up into a small mountain.

"Lin Luo, the team has been assembled. ”

Just as Lin Luo was satisfied to check the progress of the excavation of the moat? Yong shouted and ran from a distance.

"Good. ”

Heard? Lin Luo nodded lightly and said, "Let's go, follow me to see the situation in the stone refining workshop, and then we will set off." ”

"Yes. ”

Yong immediately nodded in response.

Subsequently, following behind Lin Luo? Walk towards the stone smelting workshop not far away.

The so-called stone smelting workshop looks very shabby? Except for a few simple houses, most of the area is open-air.

On the ground? Piles of charcoal and rubble can be seen everywhere.

And here? It's really a real hot scene.

Looking ahead? The entire stone smelting workshop is densely packed with dozens of shaft furnaces.

Numerous craftsmen are also by the shaft furnace? Busy adding charcoal and putting in crushed stone.

In addition, a simple blower equipment is operated to increase the temperature in the furnace.

"Lin Luo, you're here!"

After seeing Lin Luo's arrival, an old craftsman in charge of the affairs of the stone refining workshop immediately greeted him.

"How's the first batch of stone fired yesterday?"

Lin Luo asked directly.

"It's all fired according to the steps you've taught. ”

The old craftsman immediately replied, "By now, the temperature in the furnace should have completely cooled." ”

"Alright, let's go, go over and have a look. ”

"Yes. ”

The old craftsman nodded in reply, and immediately led the way in front of him, walking towards the depths of the stone refining workshop.

As the first batch of fired stones, a total of 10 furnaces were fired yesterday.

At this time, after a night, the high temperature in the shaft furnace has completely cooled down.

"Open it and see how it goes!"

Lin Luo walked directly to the nearest shaft furnace and said a little impatiently.

"Yes. ”

The old craftsman nodded in response, and immediately ordered the two craftsmen to lift the lid of the shaft furnace.

"Lin Luo, what are you burning these stones for?"

At this time, Yong, who was standing beside Lin Luo, asked with curiosity on his face.

As he inquired, he also bent down to pick up a piece of gravel from the ground.

These gravel materials are some leftovers produced in the process of digging stones on the mountain, and after Lin Luo specially asked people to collect them, they were all transported to the stone refining workshop.

Stones like this are just the most common rocks, and you can see them everywhere.

Not at all, those ores from which metals can be refined.

Therefore, Yong really couldn't understand why Lin Luo spent a lot of charcoal and manpower to build a shaft furnace to burn these stones.

"Of course, it's used to build a city!"

Facing Yong's curious inquiry, Lin Luo replied with a smile.

"If these stones are not burned, they can't be used to build a city?"

Hearing Lin Luo's answer, Yong was even more puzzled.

You know, in addition to the most common wooden houses, they also use stones to build stone houses.

But Yong had never seen any tribe use the stones used to build stone houses and burn them with fire in advance.

What's more, Lin Luo burned not the stones used to build the city wall at all, but the scraps of rubble produced by these excavations.

This kind of behavior made Yong even more incomprehensible.

By the time Yong inquired, the two craftsmen had already opened the lid of the shaft furnace and began to pull out pieces of white gravel from the furnace.

Seeing this, Lin Luo directly picked up two pieces of white gravel taken out of the furnace and knocked them on each other twice.

"Ding, ding!"

Suddenly, two crisp voices sounded.

It's no longer as dull as it used to be, and even the weight has become much lighter.

"How did this stone turn white after it was burned?"

Seeing this scene, Yong continued to ask with a surprised face.

Different from the cyan gravel in his hand, the two gravel in Lin Luo's hand at this moment had turned into a white color.

"Because they are no longer the limestone they used to be, they have been calcined into quicklime. ”

Looking at the quicklime in his hand, Lin Luo showed a satisfied smile.

At the same time, he explained to Yong out loud.

"Quicklime?"

Hearing this, Yong's head was full of question marks.

He had never heard of this stone before.

"Go get some water. ”

At this time, Lin Luo had already turned his head to look at one of the craftsmen beside him.

"I have it in me. ”

Hearing this, the craftsman immediately untied the animal skin bag from his waist and handed it over.

Now that the summer season is approaching and the weather is getting hotter, these craftsmen have to work by the fire every day, so naturally they have to carry water with them to quench their thirst.

"That's just right. ”

Hearing this, Lin Luo reached out and took the animal skin bag handed by the craftsman.

Then he put the two pieces of quicklime on the ground, unplugged the skin sac, and poured the water from it towards it.
