Steampunk, as the name suggests, where all the technology is done by relying on machinery and gears. It can be said that steampunk has developed pure mechanical technology to the extreme.

For example, without computers, these brainstorming engineering teams built extraordinarily complex differential machines. This is a kind of mechanical computer that converts the complex equation of a table of functions into a difference operation, and replaces the square operation with simple addition. To put it bluntly, this thing uses the motion of mechanical gears to calculate. Of course, you don't have to think about how fast it calculates. After all, this is a mechanical gear turning.

The first prototype of the differential machine contained more than 4,000 parts and weighed 2.5 tons. For such a behemoth, the calculation speed is only once per second. It is not the same as the computing speed of several g's when we use electronic computers now!

But with the brains of these engineers in mind, they found a way to put the differential machine into practical use.

In order to manufacture a differential machine with a higher computing speed, it is necessary to have ultra-high-precision metal parts processing capabilities and make it as small as possible to use the differential machine in a variety of equipment.

Under the shroud of red clouds, it is simply impossible to achieve such a high level of precision by relying solely on manual processing. But on dock ships, it's different.

Relying on nano manufacturing equipment, how accurate and how accurate the parts to be made. How small and small the parts should be. These nanofabrication devices can even process metal components at the atomic level to create metal gears the size of bacteria.

Then these frenzied scientists simply shrunk the difference machine, which weighed several tons, to the size of a pronunciation box, and at the same time the calculation speed reached hundreds of thousands of times per second!

Although there is still an essential gap with electronic computers, this degree of differential computer can fully meet the ordinary computing requirements.

And if you don't consider the size and weight, as long as enough of these differential machines are linked, it can be completely comparable to modern high-speed computers.

After the successful development of this new type of mechanical computer, a large number of new guns were equipped with differential machines to calculate the landing point of shells, which greatly improved the shooting accuracy. At the same time, because of the use of differential machines, mechanized equipment can achieve semi-automatic operation, which greatly saves human resources. The efficiency of the machining center inside the base has been greatly improved.

At the same time, Yun Qi also found that with his own sphere of influence becoming more and more extensive. The number of zombie colonies encountered begins to skyrocket.

The most terrifying thing is that these zombies are not only horrific in number, but also have a large number of mutants. This greatly increased the difficulty of the troops' attack, and it was not easy to transport the survivors to Dawning City.

To this end, under the leadership of the Dawning City Military Department, all kinds of new war vehicles began to contend.

Laying railways, building special armored trains, thick armor and extremely fast speeds make these steam-powered armored trains the first choice for transporting troops and supplies!

wheels, thicker armor, gun barrels, and a large number of super-heavy tanks that are frantic and completely ignore their mobility.

With two 150 mm smoothbore guns, 1,000 mm of high-strength alloy armor, and two diesel engine snorkels that emit billowing black smoke at all times, these new-age Apocalypse tanks take multi-steel riveting and gearing to the extreme. Combined with the extensive use of differential machines to simplify operations, these heavy tanks, which used to require five people to operate, now require only two people.

This makes Yunqi, which is short of human resources, unscrupulously explode the sea of tanks!

In addition to the armored forces on the ground, Yunqi also asked the military department to develop the air force.

In this world where electronic technology is ineffective, the propeller, an invention that has disappeared from the history of human science and technology for a long time, has once again burst into new vitality.

With its massive form, thick exterior armor, and outrageous barrels, this steampunk-style armored airship makes its debut.

Relying on its staggering bomb load, this big guy can be used as a floating bastion of war in the air, unleashing never-ending artillery strikes against zombies on the ground.

However, Dawning City is progressing, and these zombies are not stopping.

It seems that Yun Qi's frequent attacks are like stabbing a hornet's nest, completely angering the surrounding zombie groups.

An unprecedented multi-billion zombie assault has begun!

According to the calculations of the General Staff, under normal circumstances, it would be impossible to gather such a terrifying number of zombies. The only possibility is that there must be some of the more intelligent ones among these zombies, and it is these intelligent zombies that have driven other zombies who are not intelligent to launch a new general attack on Dawning City.

The number of zombies in this wave even exceeded millions. Such a terrifying amount has even dyed the continent into a moving sea of black!

And according to the report of the reconnaissance airship, these zombies are no longer all humans, but a large number of huge zombie beasts!

These giant beasts have been mutated and are unusually large in size. But even so, they will still die from the virus, and once they do, the flesh of these mutant beasts will swell again under the stimulation of the virus.

As a result, there are many huge monsters with a size of more than tens of meters in this zombie wave, and there are even many zombie dragons that can fly.

Seeing the intelligence coming from the reconnaissance force in front, Yun Qi was a little incredulous.

But as we all know, there is no such thing as a dragon on Earth, and the only dinosaur died 65 million years ago!

But this weird virus seems to have caused inexplicable mutations in various organisms. And getting bigger is just the simplest change, as well as attrition, alienation, and other mutations that are absolutely invisible in normal creatures, all of which are presented one by one!

It seems that this virus has completely disrupted the DNA genes in the organism, completely activating many ancient genes precipitated inside, causing these zombie beasts to have special changes similar to attrition.

And these huge flying dragons flying in the sky, and many birds should be the alienation phenomenon of wild animals after being infected with the virus.

Such a mixed army of zombies is enough to destroy a large city of tens of millions of people. If it was Dawning City three months ago, even if the fleet was fully supported, it would not be able to stop such a wave of attacks.

But now, with a new type of armor, Yun Qi has decided to have a frontal hard steel with this zombie army. After all, only blood and fire can temper a true Iron Legion!
