Lisa's demands were not met, and in the end, the result of the compromise was that Donner agreed to transfer to Lisa nearly 400 square kilometers of uncultivated farmland on the east side of the Avery Industrial Park, a three-kilometer radius, and downstream of the Avery Reservoir, and to give up a 10% stake in the SAR Bank in exchange for all the desperate money left behind after the collapse of the Cathedral of Light.

In addition to this, Donner also made a request to Lisa on the condition that he share most of the core technology: find out Ruiko's whereabouts, and if possible, bring her back to Middle-earth.

When all the conditions were negotiated, a faint smile appeared on Lisa's face, and Donner felt that this woman might be retreating and advancing, deliberately saying that she was going to build some kind of weapons factory, but the actual purpose was half of the Avery Industrial Park.

Of course, Donner doesn't feel like he's at a loss. If you can really get Ruiko back through Lisa's hands, don't talk about these requirements, even if you give Lisa all the three northern provinces plus the SAR Bank, and go to the south to start a new stove by yourself.

What's more, the gold of desperation has an extraordinary meaning for him.

Since the end of April, the weather has been getting warmer day by day, and spring is getting stronger. Looking north from the Aili Industrial Park, the newly cultivated land is filled with endless wheat seedlings undulating in the wind like tender green waves.

On the east side of the industrial park, more than 4,000 laborers borrowed by Lisa from Donner are in full swing to build the factory. Occasionally, Donner stands in his six-story office in the industrial park, watching the movement take place.

Donner didn't know what Lisa was going to get, and it seemed that Lisa didn't seem to have it in her mind. Every once in a while, she would go to the mine to see the hoisting machinery that Danny was responsible for, or come to the Avery Machinery Factory to watch the machine tool cut metal parts, or go to the steel factory to watch the fiery molten steel being poured into the sand mold.

Every few days, Lisa would come and borrow someone, and Donner would agree. He didn't have the energy to figure out what Lisa was trying to do, because he had more important things to do.

In May, part of the building of the Avery Machinery Factory was converted into a hot-rolled copper wire workshop, and the raw materials for the first month or so were all taken from the copper coins collected by the people, and it was not until July that good quality copper ingots were shipped from the copper mining area in the central part of the Silver Finch.

Donner's Desperate Gold Laboratory next to the Fog City School of Engineering had already figured out the most suitable natural insulating material - the fire lacquer gum produced in the south of the Femon Empire. The metal wire is soaked in this gum for more than a minute to form a relatively heat-resistant insulation layer on the surface. And because the fire lacquer gum is used in large quantities as a protective paint for wood, it is produced in large quantities and is easy to obtain.

In early July, just ten days after the official start of the hot-rolled copper wire workshop, the first self-excited DC generator was assembled in the newly built plant on the banks of the Isa River.

After that, it took Donner nearly a month to build the forbidden environment.

On August 15, the day before Chancellor Angela Merkel took the first anniversary of her swearing-in (just established as a legal national day by the Imperial Parliament), the world's first electrolyzed water plant was officially launched on the banks of the Isa River on the west side of the Avery Industrial Park.

Under a steel cover seven meters long and more than one meter high, covered with a desperate gold coating and shaped like a vegetable greenhouse, eight DC generators are connected in parallel, and the positive and negative poles are immersed in saturated brine tanks. The Om-type Magic Engine, which powers the generator, is exposed to the greenhouse, connected to the generator by a nearly hermetically sealed shaft.

After the electrolysis of concentrated brine, the cathode product is hydrogen, the anode product is chlorine, and the two gases are ignited to generate hydrogen chloride, which dissolves into hydrochloric acid, which can be used as a bleaching agent in the textile industry and as a pickling agent in steel mills, and is also one of the basic raw materials in the chemical industry.

In addition to producing hydrogen and chlorine, electrolytic concentrated brine will also generate sodium hydroxide in the solution, which is purified to make sodium hydroxide solution, and then used direct current electrolysis, the cathode product is oxygen, and the anode product is hydrogen, which can directly replace coke and be used as a reducing agent for steelmaking.

The theory is very simple, and the relevant equations can be known only after studying middle school chemistry, but in practice, Downer still spends a lot of energy to explore the process.

On the afternoon of August 29, Donner was trying out the oxygen cylinders produced by the machine factory when he suddenly heard a bang outside the factory. He instinctively let out a cold sweat, and his first reaction was that there was an explosion at the water electrolysis plant.

But when you think about it, in this world, even if hydrogen and oxygen are mixed and ignited, the instantaneous pressure will break through the three-dimensional membrane and release the high-pressure gas into an extra dimension, that is, it will not explode.

Moreover, the sound did not come from the direction of the water electrolysis plant, but from the eastern part of the park, which was transferred to Lisa.

Ten minutes later, when Donner arrived at the East Plaza in Avery Campus, he realized what it was.

"You've been working on this thing for four months?" Donner looked at a behemoth in the square, a little crying and laughing.

It was a giant catapult! The all-metal slewing arm was nearly forty meters long, and Donner didn't expect that the workers at the steel mill and the machine factory would be able to make such a large casting. It stands to reason that such a big project can't hide from Donner, and he must have made it in the days when he drilled in the electrolysis plant.

The structural parts of the catapult were reinforced with metal components in key areas, and a large amount of timber was used, apparently from nearby land reclamation.

At this time, a Om-type magic energy engine was struggling to turn the swivel arm shaft, slowly raising the tail counterweight weighing dozens of tons.

The Omm machine is powerful, but not very torqueful, and it is obviously a bit difficult to do this job, as evidenced by the violent vibration of the engine.

However, Lisa didn't think there was anything wrong with it at all.

"Imagine a line of these big guys behind the Great Wall! Come to the tide of beasts!" Lisa waved her arms, looking excited.

Donna looked at Lisa in surprise, he didn't expect that she would be so happy.

Perhaps, this woman has a yearning for all the killer instincts in her bones.

In fact, Donner also has a good impression of this simple and crude weapon. But reason told him that the cost-effectiveness ratio of such a weapon was too low.

"It's a pity......," he shook his head, "the cost is too high, and if you want to block the entire front, it will take at least tens of thousands, maybe hundreds of thousands...... In addition, even if the problem of the launch frequency is solved, it will not be able to cover the sky and deal with flying monsters. Also, how are you going to transport this thing to the Magic Continent?"

"Who said I was going to take them away. Lisa said with some disdain, "Can't I build a Great Wall to guard the Great Wall in Middle-earth?"

Donner smiled, no matter how he listened, he thought Lisa was quibbling.
