After the crisis passed, as soon as Lu Ya's tense nerves relaxed, sleepiness surged up, but listening to the roar of the river that was only separated by a sand wall seemed to flow overhead, Lu Ya couldn't sleep at all, and sat up straight and looked at the people who were lying on the ground and the more than 20 jeeps parked on the road, and he began to feel a little painful again.

Sinking his spiritual power into the ring, Lu Ya began to count his belongings, removing more than a dozen large and small jade bottles and two AK4 rifles and a small box of ammunition in the ring, and all that remained was the large and small bags floating in the center of the space.

The larger bag was full of gold coins, about 700 gold coins in it, and the other small bag contained the most valuable and precious thing in Luya, the magic crystal.

Unlike gold coins, which were generally stored in the city and were now managed by House, the money he had on him was only used as a precaution when he went to the Stone Tower Tribe. And the magic crystals are all in charge of Lu Ya himself, especially since he had the space ring, these magic crystals have always been carried by him in the ring, and now there are 21 first-order magic crystals left in this bag, none of the second-order magic crystals, and 43 third-order magic crystals. The summoning the day before yesterday cost Lu Ya a total of 30 first-order magic crystals and 3 third-order magic crystals, although he understood that the magic crystals were used to summon, but he always had a feeling of flesh pain.

"Hey~ natural and man-made disasters, water and fire are ruthless, and the problems that can be solved with money are not a problem" Lu Ya could only comfort himself by himself, but after he just finished saying this, he seemed to suddenly think of something, and after thinking for a while, he stood up and looked at the river outside the embankment composed of sandbags for a while, and then walked towards the city while pondering this.

After entering the city, he went straight to the iron-striking area, all the way down his head and pondered to the iron-striking area, which is rare because everyone participated in flood control, and the iron-striking area was no exception, so today's iron-striking area seemed very quiet, and the stoves that were burning high on weekdays along the way had been extinguished.

However, in the deepest part of the iron-striking area, Lu Ya still heard some jingling sounds, and with a slight smile on the corner of his mouth, Lu Ya continued to walk inside, and sure enough, he found the iron old man and the iron-striking combination composed of three rock wrestlers and a silver priest in the innermost.

These three rock wrestlers were all captives left by the Kuishan tribe last time, and the silver priest was naturally Kaul, but at this time, he was no longer as high-spirited and lofty as he had been, and his tattered black linen clothes and messy hair were burned by fire to tell him of his embarrassment at this time.

"Iron old man, you're busy" Lu Ya interrupted the iron old man who was bowing his head and directing one of the rock wrestlers to hammer, the iron old man was stunned for a moment, then raised his head to look at Lu Ya, and with a wave of his hand, the three rock wrestlers and a silver priest immediately bowed their heads and withdrew from this area.

Looking at the four people standing in the corner obediently in amazement, the corners of Lu Ya's mouth twitched a few times, but then he came back to his senses and said.

"Uncle Tie, I have an idea I want to communicate with you"

Before Lu Ya could say anything about communication, the old man waved his hand again.

"Wait a minute, who's that, right for you, my apprentices and men, go and call them all" The old man snorted at one of the rock wrestlers, rolling his eyes at Ruya.

After a while, a few people who were still a little sleepy-eyed and covered in mud rushed over, and when they saw the old man Tie and Lu Yahou, they all saluted respectfully.

"Okay, come and stand up quickly, let the patriarch open your eyes" Under the command of the old man Tie, more than a dozen clansmen quickly stood in two rows on Lu Ya's side.

"Uncle Tie, when did you become so bureaucratic," Lu Ya couldn't help but laugh.

"What is bureaucracy? What kind of technology is that?" wondered the old man.

"Forget it, it's okay, everyone is here, then I'll say it," Lu Ya cleared his throat, thought for a moment, and then asked.

"Uncle Tie, how is your plate armor researched?"

The old man was stunned for a moment, and then said, "I found some inspiration from the machine tool of the cigarette barrel last time, and then made a roller, and now it is not a problem to directly tap the steel plate, but it is indeed a little difficult to manufacture the kind of plate armor you said, whether it is cutting or plasticity, there is no good way to solve it so far, with our current technology, we may only be able to manufacture one or two sets a day, according to what you said, the cost performance is too low."

"Well, I see, I came here to think of a good way, but I still need to think about it carefully."

Lu Ya's words made the eyes of the old man Tie and the people around him brighten, but they knew that Lu Ya was powerful, and every time Lu Ya had any ideas, it was something amazing in the end.

"Uncle Tie, do you know the waterwheel?"

"What is that, can it run like a jeep?" asked the old man suspiciously.

"No, it looks like you haven't seen it, come on, you go get some planks"

After getting some planks and tools, Luya built a simple waterwheel in a short time, and drew a small ditch in the ground for people to enter the water, and then the waterwheel began to rotate because of the current, and Luya turned back to the others and said, "How is it, what do you think?"

“・・・・・・”

“・・・・・・”

“・・・・”

In the silence, it was the old man who spoke first, "This...

"Bingo~" Lu Ya shouted with a smile, and continued without waiting for the iron old man to ask.

"This shaft can be replaced with a gear, and the pinion can be used to drive the big gear, and then here, here and here, and here can be connected to the transmission belt・・・・・・"

Lu Ya spat and said for more than ten minutes, and finally finished explaining a simple prototype of a hydraulic stamping machine, picked up the water bowl that had been cooled on the side, and looked up to kill it, only to find that everyone, including the old man Tie, was looking at him with a fanatical look.

"Patriarch, this... What kind of water stamping machine is really powerful, if used properly, this stamping machine can be worth a rock wrestler, and there is no need to worry about them making mistakes like people, patriarch, are you really not the reincarnation of the beast god, you are really..."

"Hey~ Okay, okay, don't talk about it, you have to continue to overcome some of the key parts of the stamping machine, once the first stamping machine is completed, then we will be able to produce more standardized parts, and when this technology matures, I will hand it over to you another technology, which is what can really change the world," Lu Ya longed.

"Change, change the world, what is that, can't you teach us now" The old man was eager for new technology.

"There is no foundation yet, when the technology of the stamping machine is more mature, and some main conditions are met, I will teach you to study, as for its name, of course, I can tell you, it is called a steam engine!"

"Steam engine ~ ・・・・・ change the world," the iron old man muttered to himself in the direction that Lu Ya had left.

The spring flood came and went quickly, and the water level had dropped to the river bank after just a week, but in order to prevent repeatedly, the embankment made of sandbags was not immediately removed, but Lu Ya arranged a new task for Xiao Qi, digging a few small rivers and dams for diversion upstream, and there was no problem with the construction of the dam after the cement.

So Lu Ya has one more thing to do during the day, inspect the dam, and after inspecting the dam every day, Lu Ya will go to the shore to discuss the unsolved problems with the iron old man who experiments with the waterwheel, the progress of the iron old man is very fast, because Lu Ya has given him a very clear direction, so now they are already considering the impact of the waterwheel structure on the performance of the press・・・・・

Every day, when Lu Ya returned home after his work, it was already dark, and before eating, he would listen to the reports of the guards around him about the situation in the city that day.

"So many people are here today," Ruya asked after listening to the day's report.

"Yes, Patriarch, they're the same small tribe that received relief from our Blackstone City in the winter, just like those who came the other day," the guard replied truthfully.

"Well, do your best to settle these people, since you have arrived in Blackstone City, you can be regarded as a member of our Blackstone tribe, and you will not allow anyone to discriminate against them if you go down," Lu Ya ordered.

"Yes, Patriarch"

"In addition, for the new clansmen, we still have to try to find out the details, if necessary, we can let Captain Bai Lifu participate, and all the new clansmen must make it clear to them, the iron area, the brewing area, the kiln mining area These important areas are not allowed to enter for the time being, if you find that you are interested in approaching these places, you must investigate clearly, understand" Lu Ya added.

"Understood" the guard stood up.

Since the spring flood has passed, Blackstone City has successively welcomed several waves of orcs who have come to take refuge, they are all small tribes who have received relief from Blackstone City in winter, and they all set off to rush over after the weather warms up, for these orcs who come to take refuge, whether they are old, weak, sick or disabled, Luya has also chosen to take them in, not only because of sympathy, but more importantly, Blackstone City really needs population.

"Patriarch" Xiao Qi's voice came.

"Xiao Qi is here, sit down" wiped his mouth, Lu Ya got up and sat opposite Xiao Qi.

"How many new people have come in the past few days?"

"Coupled with today's 137 people, a total of 679 new people have come these days, including a total of 168 young and strong, 358 old and weak, and 153 injured."

"Well, how many people can be arranged in the city now?"

"At present, we can arrange less than 1,000 people, but if the first phase of the steel district is completed next month, we can free up another 500 places for the city," Xiao Qi replied.

"Too little" Lu Ya's brows furrowed slowly, and he reached out and gently rubbed his nose.
