On the anchorage of the dock, there is a sophisticated water clock timer, which is a little out of place with the surrounding collapse.

The water droplets "ticked" down, and the elapsed time was recorded, and finally the preset moment was reached, and the sound of cymbals sounded.

"Close, ignition!"

As the representative of the Scales Chamber of Commerce of the Eternal Order, Santos, the fat merchant, stood on the high platform and announced loudly.

With his order, the workers who had already prepared were instantly busy.

These people are all employees of the Chamber of Commerce, and they have all been screened at various levels, and in addition to their innocence, they are all hardworking and capable.

In accordance with the requirements of the operation manual, under the instructions of the supervisors, the workers first closed the gate as an exhaust device, then sent a truckload of coal into the combustion furnace, and finally placed the water absorber into the seawater when the instrument panel showing negative pressure reached the specified scale.

The sound of pumping polluted seawater, from "gurgling" at the beginning, quickly turned into "boom".

All of this water flows through a special purification kettle, where it reacts with a purification potion made from the crystals of the pink lake of Tuka to cleanse the demons of the remnants of their flesh and blood before being expelled.

The discharged water is discharged into the ocean beyond the fjord through several pre-laid pipes, and at the mouth of the fjord, several pumps are also installed on the rising ice wall to pump the seawater from beyond the fjord.

According to previous estimates, as long as more than 100 water purification pumps work smoothly around the clock every day, it will only take about five days for all the seawater in this fjord to be purified.

The remaining Demon Lord will incarnate flesh and blood, and its concentration will be so low that it can no longer affect other sea creatures, and the crisis will be resolved.

While the engineering team of the Scales Chamber of Commerce of Eternal Order was busy, many city dwellers flocked to the periphery of the police cordon to see how the new thing like the "purification water pump" worked.

Due to the increasing number of people gathered, and even alarmed the Praetorian Guard, General Potbelly sent some men to follow him, responsible for maintaining order near the dock site.

"Lord Pasha," approached Quest, a Medici military nobleman who looked a little similar to Santos, pointing to the rumbling purification pump in front of him, and asked, "Can the pump only be used this once?" ”

With a slight smile, Quest replied, "Of course, these pumps can only be used once, they can be reused after removing the part dedicated to purifying the demonic pollution. ”

After speaking, he raised his head to signal the group of people coming from outside the cordon, and said with a smile: "The people who will buy these equipment are here." ”

Khalil Pasha, dressed in a light green robe, approached surrounded by a group of guards, and greeted Ques from a distance.

"Good day, Pasha the dragon!" said the Emperor of the United States, who ruled several coastal cities, and greeted the young blue dragon with the famous chin salute of his rule, "These purification pumps are truly a great invention. ”

As early as two days ago, after receiving an order from the Pharaoh along with Zagan, the archipelago leader, Khalil took the initiative to contact Quest.

When Quest heard that he wanted to "order a floating beast as a vehicle", he gave him a clear and affirmative answer, but the later offer still exceeded Khalil's expectations and needed further communication.

However, the young Blue Dragon immediately recommended the "purification water pump" that Sneijder and himself had jointly invented, and pointed out that "this tool can solve the problem of stagnant water in the mines, and can greatly improve the efficiency of the Usang slave miners." ”

Moreover, compared to the astronomical purchase cost of Leviathan, the selling price of these purification pumps is simply extremely cheap, and even a fraction of the former.

Today, when the water purification pump started, Khalil sent a letter in advance, telling Quis that he would come to congratulate him in person.

However, the young blue dragon knew very well that this Pasha actually wanted to come over and see the actual effect of the water pump when it was running.

"As you promise, everything is going well......"

After saying a set of scenes, Quest took the Pasha and the equally curious pot-bellied general to take a close-up tour of the "purification pump", and he also used professional words such as listing numbers and making comparisons to make a wave of commercial boasting.

"After the pump system is put into operation, the only labor required is fuel refilling. As long as there is enough coal and enough water, the purification pump will be able to continue to work. ”

"What if the depth of the pit is too deep, and how deep can this pump draw up the stagnant water inside the mine?"

Obviously, after moving the mind of procurement, this Pasha must have done some homework when he went back.

In the face of consumers' doubts, as a "professional" who can make Yugros judge the magic capital, it seems that due to the complaints of the blue dragon race, he is very talented in the skill of "speech", and he explained unhurriedly:

"The structure of the pit is basically excavated in the form of multiple platforms, and a platform is carved out at each depth. In the mine, due to groundwater seepage, most of the lowest platforms will have a certain amount of standing water. ”

Throwing out the "information increment", Quest instantly focused the attention of the two people on himself, and he continued: "And this stagnant water, at present, is manually drawn little by little to the surface and discharged, when the mine is dug a little deeper, and the groundwater seeps out faster than the rate of discharge, the pit will be abandoned - because it cannot be mined, and there is a danger of collapse." ”

"But if there is such a pump, although it can only pump up to 20 yards of water at most, each platform inside the mine can build a trough and place one or more drainage pumps to draw the water out in layers and stages. In this way......"

“...... The tunnels can be dug deeper," said Khalil Pasha, who had already figured out how the graded tunnel drainage system worked, as he looked at him encouragingly, "More slave miners will be able to be placed, and more deposits will be excavated!"

"See, what do you mean by 'smart man'," in an exaggeration, the young blue dragon seemed to say to the pot-bellied general, but in fact it was flattering Pasha Khalil, "a little bit of it, no need to explain." ”

"That's natural, who made you two the Pasha ministers who shepherd one for the Pharaoh?"

The big-bellied general was as good as a stream, and then echoed.

After talking for a while, because of some "second-hand" parts, Quies generously discounted the order for the mine pump, and even had the intention of giving up some more discounts as the conversation was enjoyable.

This almost frightened Santos, who had just come over, and the senior manager of the Scales of Eternal Order couldn't help but say: "My lord, you can't let it anymore, if you let it again, you will lose it!"
