Chapter 186 -182, 183: This Is Not a Drill (Double Monthly Ticket Extra Update)_2

He Xingzhou said, “The design consists of two rectangular coaxial coils placed one on top of the other, with a gap in between. The projectile is a rectangular block that can pass through the gap between the two coils for acceleration.”

“Since the projectile carries a continuous current, the magnetic field produced by the projectile seemingly ‘cuts off’ the magnetic field of the accelerating coil as it passes through, then abstractly reconnects with the magnetic field of the next coil.”

“In this continuous reconnection process, the projectile is constantly accelerated, while gaining the advantages of both the inductive electromagnetic gun and the electromagnetic railgun!”

Everyone understood the principle, and He Xingzhou sent over a diagram of his design.

This was a cylindrical electromagnetic reconnection cannon, primarily composed of a cylindrical armature wound with synchronous induction coils.

By controlling the current, they achieved the effect of electromagnetic acceleration and magnetic field reconnection.

“This design, if we can precisely control each reconnection, then the projectile can continuously accelerate within a small volume, ultimately achieving the same effect as a long-range electromagnetic railgun!” Bei Xiangbei said, “We need to attempt this immediately!”

He Xingzhou said, “It would be best to immediately manufacture a prototype. If the experiment succeeds, proceed to mass production and dispatch it to the front lines right away!”

Bei Xiangbei also knew it was a race against time, with every second counting.

He immediately said, “We’ll start right now, and as soon as the experiment succeeds, we will begin manufacturing!”

…

While they were researching the electromagnetic reconnection cannon, the battle in Busan had already commenced.

The initial sequence was similar to the one on Sakura Island’s Diaozi District. The Zerg first used low-level mutant creatures to draw fire, and once the resources were depleted enough, they dispatched the beetles to land.

With prior experience, they weren’t as unprepared this time.

The specially equipped tanks used armor-piercing bullets and high-explosive rounds to inflict significant damage on the beetles. However, when the black beetles landed, the effectiveness of armor-piercing and high-explosive rounds was limited.

At the river mouth, the Zerg attacked the fleet, and several warships were destroyed.

“Hold on for another half-hour, and most of the mutant creatures will be dead!” Commander Jin Chenghuan shouted in the command center.

“We must hold the coastal defense line!”

Of the first wave of landing black beetles, half were blasted away, leaving fewer than fifty. If they held out, there was still a chance to maintain their defense.

But despair took hold when yet another wave of black beetles, even larger, appeared in the ocean alongside various red and green beetles. Altogether, they numbered around six or seven thousand.

The scene resembled a massive armored assault charging the defense line!

Underwater, giant Zerg also smashed into the defense lines.

A drone captured footage of a tentacle, dozens of meters long, pulling a small ship into the sea!

“Boom!” A Tomahawk cruise missile hit it, painting the ocean crimson, but the creature didn’t surface and instead disappeared into the depths.

In the deep waters, the monsters madly crashed into the underwater interception nets. Some even carried electric current, causing the nets to collapse and the river mouth to be breached.

The commander of Bai Ying observed the state of the defense line and said, “Retreat and defend. Our missiles are ready.”

“Retreat!” Jin Chenghuan ordered, feeling utterly drained.

This was Busan! Unlike Diaozi District on Sakura Island, even if they retreated to the land defenses and destroyed all the beetles, the city would suffer enormous losses!

Moreover, the monsters had opened the river mouth, and from the Lodong River, they would enter the city.

Greater disaster and chaos loomed!

The soldiers fell back to the land defenses, and countless missiles rained down, obliterating the Zerg around the coastal defense line!

With it, the once-thriving first port of the island was reduced to ashes!

“Busan has fallen!” In this moment, countless islanders mourned.

“Our home is gone!”

“The Zerg have entered the river and are heading inland!”

“What are we going to do now?”

No one could answer… After enduring such survival struggles, what awaited them were only more confusion and fear!

…

“Twice, twice the coastal defenses failed!” The whole human world was shaken by this!

Though small, these two places ranked among the world’s leading industrial and technological powers.

Even with their military might, they couldn’t guard the river mouth against the Zerg.

If the Zerg landed elsewhere, could they hold the ground?

Pessimism spread through human society. Some even began feeling despair, proclaiming the end was near, suggesting giving up resistance, or seeking refuge in heaven before the Zerg came.

Others indulged, believing it was better to find some happiness before being wiped out by the Zerg.

Some individuals and organizations called on humanity to unite in resistance against the Zerg, advocating for the development of advanced military technology.

Various phenomena emerged one after another.

A piece of news redirected the world’s attention to Shen Zhou.

“The third wave of Zerg is closing in on Shanghai! It may land within ten days,” international media reported.

“There’s nothing we can do! Humanity is no match for the Zerg, flee for your lives!”

“Learning from the previous two experiences, you could just abandon Shanghai and use missiles to obliterate the Zerg!”

“The apocalypse is here, and only those who believe in the God of Oran can find refuge and salvation!”

“Humanity has completely withdrawn from the oceans, retreating inland!”

“Sigh, once again, many lives will be lost this time!”

The news was filled with pessimism.

Due to two failures, even netizens in Shen Zhou felt the pressure from the Zerg.

*They couldn’t help but wonder, “Can we really hold the line?”*

More news arrived, saying that the Zerg attacking Shanghai this time numbered even more than the previous two waves put together.

This news left people restless.

“What are we going to do with so many Zerg?”

“We can’t afford to lose Shanghai, or the Zerg will travel down the Yangtze River and soon spread nationwide!”

“On land, even if the Zerg and mutant creatures appear, we can hunt them down. But in the river, how are we supposed to catch them?”

“Shanghai has over twenty million people; how can we evacuate? Moreover, it’s one of our economic centers. If it turns out like Diaozi District and Busan, we’ll suffer a huge blow!”

The entire nation focused on Shanghai.

At this time, the Xuanwu Executive Officers released a statement: “Thanks to the hard work of our citizens and soldiers, we have completed the construction of the Steel Great Wall along the coastal segment of Shanghai.”

“The Steel Great Wall is operational, and we will protect the safety of Shanghai!”

The news immediately uplifted the people’s spirits.

“It’s been built so quickly! A true miracle!”

“With the Steel Great Wall, we likely won’t experience failure like theirs!”

“The Steel Great Wall is just built and must now be tested. Let’s hope it becomes our stalwart barrier!”

“@Shanghai, keep fighting; we stand with you!”

…

The Zerg swarm closed in, and the Xuanwu Army dispatched ships and fighter jets daily to bomb the coastal areas, trying to reduce the number of mutant creatures and Zerg.

Meanwhile, at the Electromagnetic Weapons Research Institute, He Xingzhou’s electromagnetic reconnection cannon passed its trials and was expedited for manufacturing.

He Xingzhou demanded at least a hundred electromagnetic reconnection cannons be produced within ten days.

Additionally, he also designed a large-scale multi-stage electromagnetic reconnection cannon, which used magnetic field stacking to double the projectile’s thrust. Its power would be several times greater than those of single-stage electromagnetic reconnection cannons!

To ensure its manufacture before the battle began, He Xingzhou personally went to the munitions factory to oversee the production process.

Eight days later, in Shanghai.

Most of the high-rise buildings along the coast were deserted, with the population already evacuated.

Yet, the massive urban area of Shanghai couldn’t be fully evacuated, and most areas had to continue with normal life and work.

At around five in the morning, many people were still deep in sleep when piercing sirens rent the air, followed by the same sound resonating in streets, neighborhoods, and homes.

This was an air raid siren, and it wasn’t a drill!
