The cable car follows the ropeway deep into the tunnel, and the dim light overhead shines on both sides of the dome in arcs, and looking forward looks like you are inside a giant snake, which is the rib cage of the snake.

151 is a huge underground ant nest, even the staff inside the base, there are few to go through all the tunnels of the entire base, its main structure from the top down is a huge H, different parts of this H-shaped tunnel belong to different departments of the base, 104 Temple is in the main cave on the left, responsible for the maintenance of the red lotus, and 105 main cave is on the right, responsible for other tasks, the personnel in the two main caves do not interact during working hours.

151 is one such place, and without a map, you don't know where the deep tunnels you see lead.

They may take you to an unexpected destination, especially in the dead of night when no one is coming, and it is entirely possible that you will not be able to find a way out for several hours in 151 until you bump into your comrades at work the next morning, so the workers and cadres in the base never follow the path they are familiar with.

Old man Ji took a group of cadres from the equipment department and the logistics department to sit in the cable car, they got off the platform in the 105 main cave and went to the 112 workshop in a hurry.

There are a total of three giant machinery maintenance workshops in the base, 110 is the special workshop for Red Lotus, which is the most important one, 111 is the backup workshop, which is currently empty, and 112 is the coolest one.

Because it's home to some of the coolest machines in the world.

Codename Mock Wind.

The only full-vacuum tube computing core steam power technology verification machine in human society.

This is a project that Old Man Ji personally led the technical team to tackle, and no one could see that this bad old man who always has a stinky face on his crotch on weekdays has a Warhammer 40K heart, and can make such a punk thing, the original intention of the design of the mocking wind is derived from people's concerns about the super electromagnetic pulse - when the 001 Seraphic Angel erupted, it not only almost overturned the North American continent, but also caused the most powerful and longest-lasting electromagnetic pulse seen by mankind so far, which reimbursed half of the world's electronics and all satellites, The high-energy charged particles in the upper atmosphere do not disperse for several years, and even affect the Earth's magnetic field in turn.

This turbulent angel made the weapons in the hands of humans scrap overnight.

EMP is the natural enemy of any precision electronic instrument, especially the giant machine, its combat relies on the computing core's powerful computing power of trillions of floating point operations per second, but the more sophisticated the integrated circuit, the more afraid of the electromagnetic pulse, unless you use a huge Faraday cage to completely wrap the whole giant machine from the world, otherwise the surge current caused by the EMP can burn the giant machine into scrap metal in a few seconds.

Imagine such a situation: the second angel with the ability to cause a super electromagnetic pulse burst descends (Old Man Ji believes that there must be such an angel), which can paralyze the human communication system, command system, and decision-making institutions for a long time in an instant, and the modern civilization of mankind built on Maxwell's equations is helpless against this kind of attack that directly hits the soft underbelly, and it can make the giant machine drop in place from a distance of 800 kilometers.

Old man Ji still remembers the disaster in the Great Collapse.

So he presided over a peculiar and even bizarre project (if it weren't for the fact that Old Man Ji's qualifications were too old and his status was too high, such a nonsense project would have been difficult to pass the approval), and everyone was busy upgrading the system, making the computing core more and more sophisticated, and the computing speed was getting faster and faster.

This old antique is the same age as Old Man Ji's father.

- Vacuum tube computer.

What a Luoyang shovel, this grave is so dug that even the captain of Jin has to give a thumbs up and say professionally.

If there are four words to describe a vacuum tube computer, it is: stupid, big, black, and thick.

Dozens of tons of gadgets can't catch up with the "return to zero" calculator, if it weren't for the super EMP to burn the calculator together, it would be better to use this thing to pick up a calculator, but it has an irreplaceable advantage - not afraid of lightning strikes, not afraid of γ rays, not afraid of electromagnetic pulses.

It's simple enough, what is a vacuum tube? A sealed glass bulb inserts three metal electrodes, the inside is pumped into a vacuum, with a single conductive function, just such a simple thing, the big wrist is thick, the small finger is big, the vacuum tube of the 21st century is almost extinct in daily use, only some high-end audio equipment will use the vacuum tube as a machine bladder, the pursuit of a "treble sweet mid-pitch quasi-bass deep, in a word is transparent".

A vacuum tube can represent a 0/1, the vacuum tube computer inserts thousands of glass bulbs into the board and strings them together to form a logic circuit, you can imagine its size, weight and power consumption are difficult for modern people to predict, with the microelectronics technology of the 21st century, the bulky computer that covers an area of more than an entire manor is shrunk to a huge scale integrated circuit is the size of a fingernail of a small finger.

But with a wave of his hand, the old man Ji turned the clock back to the forties of the last century, the vacuum tube computer is not much different from the first computer in human history, ENIAC, in terms of technical level, and it is not much more advanced than the bomb machine built by Alan Turing in the Bletchley Manor, and the old man Ji resolutely carried this old antique to the battlefield, just like the era of starship bombardment, one side put the Shenwei invincible general cannon out on the side of the ship - backward? Backward, but the shells can ignore the other side's guidance interference and bombard the damn, backwardness is not a disadvantage!

It's so fucking Warhammer 40K.

If one day the angels break out again to participate in the super electromagnetic pulse that sweeps the world, and all the giant machines of mankind are scrapped, then Mocking Wind will lead a large group of vacuum tube punk steam-powered hydraulic giants to the battlefield, think about it! What kind of scene was that, steaming giants walking on the ground, their brains were vacuum tubes glowing and hot, the driver was sitting in the cockpit, his hands and feet were covered with steel cables, in front of him was a green CRT monitor and mechanical instruments, and everywhere there was a roar and a strong smell of engine oil—

It's really JB wonderful, but it's a pity to think too far...... Old man Ji shook his head.

He stood on the work surface with his hands in his pockets.

Unlike Red Lotus, this giant machine was pitch black, with thick pipes and cables hanging from the fracture in the waist and abdomen, like the internal organs of a giant.

It was covered with a huge plastic sheet, and the workers of Workshop 112 were pulling the steel cables and lifting the plastic sheeting.

Old man Ji slapped his hands vigorously in the empty cave and said loudly:

"Let's try a hand first! Little ones! Burn the boiler up! ”
