Humanity is missing, luckily I have billions of clones.

Chapter 224 Magnetic Monopoles
In countless mines, numerous large-scale mining equipment roars and explodes all day long.

A huge amount of rocks were crushed and entered the subsequent disposal procedures. The initially processed minerals were then sent to the smelter. Under the high temperature of the nuclear fusion reactor, they were gradually separated from the impurities and eventually turned into pieces of special alloys in the form that Li Qingsong hoped for. After various processing in many foundries, they finally became individual components.

On numerous space elevators, countless shuttle buses roar all day long, rushing straight into the starry sky or suddenly falling from the starry sky with an acceleration of dozens of Gs.

In space, countless asteroids, dominated by V432 Pegasus, moved chaotically. Skynets were spread out, blocking out any threats from space that might affect construction.
Countless large, medium and small transport spacecraft shuttled through space, either nimbly dodging small celestial bodies, or directly smashing them, or simply rushing through them, transporting the facilities and materials that Li Qingsong had worked so hard to produce to the thousands of target planets.

Large machines roared and roared, drilling into the ground of the planet like a giant dragon. Endless rocks were excavated and piled up beside the construction site like mountains.

Countless clones and general-purpose robots worked like ants, either in the control room or on the front lines, building facilities that were so large that they seemed impossible for humans to build.
High-precision steel plates are spliced together with special welding to build huge water tanks like building blocks. The ultra-pure water plants specially prepared for each proton decay detector improve their purity over and over again with the supply of large amounts of water ice collected on site or transported from outside.

The ultrapure water used in the detector cannot be transported externally because it would be mixed with atoms or molecules of other substances during transportation.

They can only be manufactured on site and then poured into water tanks through special means to ensure that they are not contaminated.

Even so, they need to be cleaned regularly because the molecules and atoms that make up the tank will diffuse into the water.

This massive construction project took up the entire energy of Li Qingsong's more than 3 million clones and about 500 million blueprint scientists and engineers.

Currently, the Blueprint population has reached approximately 15 billion people. Based on Li Qingsong's governing philosophy of "science first," which prioritizes science, granting only scientists status and honors, and rewarding them with commendations. In other fields, no matter how significant their contributions, Li Qingsong offers little reward. These 15 billion Blueprint people have produced approximately 1200 million qualified researchers, far exceeding the average civilization.

At the same time, Li Qingsong did not hide the process of fighting against the intelligent machine Scourge in the previous stage from the Blueprint People.

The people of Blueprint also truly felt how dangerous the previous period was.

Once their side is defeated, both the master and themselves will become slaves of the Omnic Scourge.

It was like walking on a tightrope, and we managed to gain this precious time for development at great risk.

In this case, how can the blueprint people not do their best?
Even though our own scientific research capabilities are weak and our numbers are small, and we really cannot provide much help to the master's technological development, we can still find out the gaps and eliminate the blind spots in the master's scientific research system.

So, Li Qingsong charged ahead, and Blueprint scientists followed behind to check for omissions and fill in the gaps, and the scientific research forces of both sides were organically combined.

After decades of construction, the large-scale proton decay detector was finally built. Li Qingsong left about 1.2 million clones for daily research and maintenance of the detector's normal operation, and then turned around and invested a large amount of scientific research resources in another extremely important construction.

Magnetic monopole detection device!

The magnetic monopole is another particle predicted by Li Qingsong's existing grand unified theoretical framework.

Unlike normal magnets that have north and south poles, a magnetic monopole carries only one magnetic charge, that is, it has only a "south pole" or a "north pole."

Li Qingsong didn't know whether magnetic monopoles actually existed. But at least for now, his theoretical framework predicted their existence. If the existence of magnetic monopoles could be verified, Li Qingsong's grand unified theory would receive a crucial validation, potentially expanding upon many of its concepts.

The status of this detection is equal to that of proton decay detection. It is equally important and indispensable.

Because these two detections will verify two aspects of the grand unified theoretical framework.

In Li Qingsong's theory, magnetic monopoles were extremely numerous in the early days of the universe, but now, as the universe continues to expand, its density continues to decrease, and its number per unit volume has become extremely scarce.

At the same time, the lifespan of magnetic monopoles is extremely long, even comparable to that of protons.

Therefore, the device for detecting magnetic monopoles must have two characteristics. First, it must be large enough.

Because only if it is large enough is it more likely to react with the extremely rare magnetic monopoles that exist in interstellar space.

The probability of a magnetic monopole hitting a planet is always higher than the probability of it hitting a spacecraft.

The second is that it must be able to interact with the magnetic monopole. Because only by interacting with each other can a phenomenon be generated that is observable enough for Li Qingsong to see.

In this field of detection, Li Qingsong decided to use a new type of detector.

This detector is mainly based on the isotope of helium, helium-3.

At extremely low temperatures, helium-3 enters a superfluid state. When placed under a magnetic field, superfluid helium-3 forms quantized vortex lines.

If a magnetic monopole penetrates a detector composed mainly of superfluid helium-3 at this moment, its magnetic field will interact with the helium-3, causing extremely small fluctuations in the helium-3 magnetic field.

At that time, by observing this magnetic field fluctuation, Li Qingsong will be able to confirm whether a magnetic monopole has really penetrated the detector and what its nature is.

Like proton decay detectors, magnetic monopole detectors are also extremely sensitive to interference. However, they cannot eliminate interference by shielding against thick rock layers, so they can only find ways to improve resolution.

Therefore, in order to achieve sufficient accuracy, Li Qingsong had to make the magnetic monopole detector extremely large.

In Li Qingsong's plan, the first generation of magnetic monopole detectors will have a total volume comparable to that of a heavy transport spacecraft, with a total mass of more than 1000 million tons, and the longest part will even exceed one kilometer.

In such a huge detector, Li Qingsong poured millions of tons of helium-3 into it and began to try to capture magnetic monopoles.
