There was rubble everywhere......

When a horse's hooves are trampled on the ground, they immediately bring up a cloud of dust.

The dry wind blowing from the desert takes away the last bit of moisture from the barren Gobi Desert, and the water element in the air is very thin.

The guide of the village of Uta wrapped himself in rough linen and showed only one pair of eyes, and he rode the Gubolai horse to the front, refusing to eat some food and water only before dawn, and not eating all day, as many villagers did in this dry spring to save food.

Recently, a group of robbers came to the Gobi, in the past, when there was a food shortage every spring, the robbers would venture through the desert and run to this area to rob houses, of course, this group of robbers also knew that they could not force the villagers to a dead end, otherwise they would not be able to find anything next spring, but the appearance of these robbers often made life more difficult for the villagers who were already struggling with food and clothing.

A week ago, a group of bandits were chased by Andrew and Samira on the Gobi for three days, and finally retreated into the desert in disarray, and the dead robbers' bodies now hang on wooden crosses in the Paglos Pass, attracting dozens of vultures to hover over the pass.

The reputation of the vigilantes in the Deserted Lands outside the Paglos Pass has now spread throughout the villages.

The investigation team entered the depths of the Wastelands, accompanied by two magicians, Carl and nine knights from the support squadron, Surdak's vigilantes, and a guide from the village of Uta in addition to Viscount Frank and two assistants.

It was not the first time Karl had entered the barren land, and the group of the guard battalion rode horses, looking at the knights' collar of Surdak from a distance at the highest point of the stone slope, and the pus-covered mountain was at least fifty or sixty kilometers away, and only in clear weather could you see the pus-covered mountain hidden under the billowing smoke.

And now, in everyone's sight, only gray clouds can be seen in the distant sky, like a majestic mountain.

It is only in windy weather that the volcanic ash from Pubao Mountain is likely to blow here.

In the dry season at the turn of spring and summer, not a drop of rain has fallen here for two consecutive months, and it is difficult to dig out damp water vapor even if you dig three feet into the ground on the Gobi.

The group arrived at the site where Surdak had fought two rebels and found some remaining black blood stains on some of the rubble.

The ogre saw the stone he threw out from a hundred meters away, shook off his big foot and ran over a few steps, picked it up, and told Viscount Frank about the fierce battle at that time.

Viscount Frank squinted at the barren land, and his mind seemed to recreate the battle scene at that time.

The two magicians who had barely said anything along the way jumped off their horses, took out a few magic crystals from their magic pockets, and placed a magic pattern circle on the stone ground, and then put the hexagonal magic crystals in the center of the magic circle, the two magicians stood on both sides of the magic circle, and entered a trace of magic power into the magic circle, and the entire magic circle began to operate, and the magic crystals in the center of the magic circle were filled with magic elements of various colors.

It is not known what the two magicians are doing, but they can roughly guess that they are performing some kind of magic test.

Viscount Frank's two assistants began to collect some bloody stones at the scene, and also surveyed the general extent of the fighting field, and the group stayed here for most of the day before the two magicians completed the magic test with a tired face, and the two magicians told Viscount Frank with great certainty that no anomalies of the magic elements were found here.

Viscount Frank lowered his head and thought for a moment, everyone waited on the sidelines, and no one disturbed his thoughts.

When he raised his head again, Viscount Frank's face softened a lot, at least when he looked at the security team, he was no longer the kind of cold eyes, and he said to the people of Surdak's security team: "Thank you for your full cooperation in the past two days!" ”

Then he turned his head to Carl next to him and said, "Then Squadron Leader Karl, let's go to the next survey point!" ”

"Yes, Viscount Frank!" Carl readily agreed.

The mission then left the barren land without stopping.

Knowing that the group had crossed the Paglos Pass in the distance, Surdak breathed a sigh of relief, after all, there was not only a messenger of the Dark Goddess in the village, but also a succubus from the Flame Hell, and whoever these two were exposed would be a disaster for Surdak.

……

Surdak waited for nearly a month, and the White Elephant Merchant finally delivered the second batch of steel and a large vat of saltpeter powder to the village of Wall.

Old village chief Bright directs a group of villagers to unload bundles of thumb-thick steel bars from the four-wheeled wagon, which will be used on the main dam of the secondary reservoir.

The foundation of the secondary reservoir embankment had been officially poured a week ago, and the steel bars were protruding from the concrete foundation, and a group of bricklayers used iron wire to weave a network of embankments on these thumb-thick steel bars, and the carpenters erected long planks on the front and back sides of the embankment, waiting for the foundation of the embankment to be stronger, and then further pouring the embankment of the secondary reservoir.

Thirteen four-wheeled wagons loaded with this steel drove into the village, and the old village chief learned that Surdak had invested a large sum of money in the cistern.

"Dak, can you get the sulfur from the open-pit sulfur mine on your territory in exchange for this steel?"

"Of course!" Surdak said confidently to the old village chief.

The old village chief watched a group of villagers move steel out of the car, and said with a melancholy expression: "I heard from Charlie that the sulfur mine in the rocky area is about to be exhausted......

With large quantities of sulphur ore being transported to the city of Highlandsa and sold, no one knew better than the old village chief Bright what the value of the yellow crystals mixed in the rocks was.

Surdak smiled faintly and said: "No problem, Pubao Mountain is not only such a lava river, when the sulfur ore in this rocky area is exhausted, I will take them to change places, Pupu Mountain is so big, there will be no shortage of sulfur ore." ”

He is not thinking about the secondary reservoir now, and even this transaction Surdak has already put three . The steel for the cistern was also ordered, and he had to consider a fourth-class cistern, which was at least twenty times larger than the second-class cistern, and a larger fifth-class cistern, and now looking at Surdak's plan, the entire cistern occupied almost a large area of the upper valley.

Once completed, the reservoir will become a huge artificial lake hanging over the heads of the villagers.

"That's good, in fact, if you want me to say that this reservoir is already very good now, as long as this reservoir is filled with water in the summer, it will definitely survive the dry season of the next spring, we don't need a bigger reservoir, I want to say! Let's level out this land, we should build a grand knight's manor, you have now become an official knight of the Green Empire, and you should pay attention to your own decency in ordinary times. The old village chief, Bright, said to Surdak earnestly.

But Surdak shook his head and said: "This is far from enough, by this time next year, there will be at least a few hundred acres of land on the side of the river bend and tidal flats that need to be irrigated, and the village of Vol will not always be so poor, it will become rich little by little, and more people will be willing to move to live in the village of Vol." ”

Seeing that Surdak couldn't say the law, the old village chief Bright could only keep his mouth shut, standing on the embankment and watching the lively scene at the secondary reservoir construction site.

"Knight Surdak, the batch of magical materials you ordered from the magician of Dalla has arrived." The head of a White Elephant Firm, who was in charge of the delivery, came to Surdak, saluted him respectfully, and said.

Then he beckoned behind him, and two clerks from the merchant house carried an oak barrel with straw rope wrapped around it, carefully placed it in front of Surdak, and then pried the cork off the barrel, picked up a little white powder from it, and handed it to Surdak.

The head of the comptoir struggled to squeeze out a smile and continued:

"Magician Dalla told me to tell you to use it with caution, this thing is not safe, and it is very dangerous for those who are not familiar with it."

Surdak nodded and replied mildly:

"Got it, convey your thanks to the Magician of Dala for me!"

After speaking, he took out two silver coins from his bosom and stuffed a silver hammer into the person in charge of the trading bank.

The person in charge of the comptoir's eyes lit up, and hurriedly took it in his hand, and praised Surdak very humbly:

"What a generous knight you are!"

……

Over the next few days, Surdak set up a marching tent at the foot of the hill outside the village.

Then it was immediately after him to drive everyone away, and even he blessed himself with the Divine Blessing Body.

The last thing that is lacking here in the village of Wall is charcoal and sulfur, after preparing the toner and sulfur powder, Surdak began to concoct black powder outside the marching tent, looking alone, in fact, it is not the case, he also has the magic notebook by his side, Celia. Cooper stayed with Surdak throughout the process, explaining the uses of various glassware and the basics of Potions.

Surdak began to pour some charcoal into the cup, stirring and filling it with sulfur, and waited until he did the final step to fill it with a certain percentage of nitrate.

Surdak has done this kind of concoction process no less than dozens of times.

In fact, even if you know a little bit about the recipe of black powder, but when you really start making it, you will find that this thing is not as simple as imagined, the gunpowder is debugged, more like a firework that can burst into a strong flame, even if it is tightly tied into a cylinder with parchment paper and blocked at both ends with yellow mud, but this large firecracker still has no power.

"Are you sure you want to do that?" Celia. Cooper saw that Surdak was repeating what he had done before, and he couldn't help but stand on the page and complain to him.

Surdak wiped his hand on his apron and looked at Celia seriously. Cooper says:

"I don't know what's wrong, but I know that it should be almost successful, this thing can't be considered magic, this thing is more like Hextech, if you really want to classify it academically, it should be physics and chemistry."

He was right to Celia. Cooper was still full of affection.

No matter what kind of knowledge, as long as Surdak asks, he can always hear Celia. Some advice from Cooper.

Celia. With a strange look in his eyes, Cooper propped his chin in one hand and muttered behind the black fence of the page, "I find that I don't understand you more and more." ”

Surdak stopped what he was doing and said to Celia. Cooper said, "What's wrong? I make black powder because...... I got the recipe for the black powder! It's just that I don't know a small detail that makes the most of it. ”

Celia. Cooper pursed his lips and said to Surdak: "I don't mean this, I've seen a lot of great potions, I'm not interested in potions, I mean some of your methods, you build such a large cistern in the village of Wall, and you don't divide the land here as a knight's domain, it's not as simple as building a house, investing so much, what do you want?" ”

Surdak lowered his head again, stirred the gunpowder in his hand, and said, "I'm just making good on my promise......"

By the time Rita delivered food to Surdak in the evening, Surdak had already discovered a minor flaw and improved it.

Just outside the tent, Surdak put on a gorgeous fireworks display for Rita.

Shocked Rita was speechless for a while, but kept remorseful: "It's a pity that Natasha and Little Peter are not ......"

……

'Boom'

With a loud bang, the limestone blocking the river was blown apart.

A group of kobolds stood on the embankment of the artificial canal, looking in horror at the cracked limestone in the river, and instead of being torn apart, the huge limestone was full of huge bulges, which were covered with dense cracks.

It is also the amount of black powder that Surdak tested after dozens of experiments.

At the end of the explosion, a group of kobold slaves trembling down the riverbed, picking up pickaxes to dig up the loose rocks, and the two kobolds used a stick to lift the rocks to the embankment on the shore, and several bricklayers were building a low flood control dam with the bricklayers and filling the gaps in the stone wall with volcanic mud.

With gunpowder to open the way, the two largest roadblocks on the river were finally cleared by explosives.

Eight hundred kobold slaves poured down the river embankment at the same time, the footsteps were like a silent drum in this land, after nearly a month of captivity, this group of kobold slaves could eat two full meals a day, although the labor intensity on the side of the artificial canal construction site was a bit large, but this did not affect the body of these kobold slaves to recover a little bit, and their bodies became very strong.

A large amount of gravel was carried up from the bottom of the river, and the kobold slaves did not need to rest to clean up this section of the river in one go.

They were only a little afraid of the loud noise, but they were almost all familiar with it these days......
