"Let's wait." Han Feng asked Wu Yuli to stay in the Unimog RV, and he followed the energy transmission pipeline that was connected outwards to the center of the entire underground space.

At this moment, the most middle position of the entire space is naturally the Large Hadron Collider.

The Large Hadron Collider, built with three-pole low-temperature superconducting magnets and a 60-kilometer-long circular tunnel, is the goal of Han Feng's trip.

The Large Hadron Collider works by emitting two streams of high-energy particles through two different tubes from opposite directions.

At the same time, these two tubes are kept in an ultra-high vacuum state, which can make the two beams of high-energy particles move forward at close to the speed of light, and these two high-energy particle beams can walk in a circle in the electromagnetic cyclotron of the Large Hadron Collider in just a few microseconds.

In just one second, the entire beam of high-energy particles can travel more than 5,000 laps in a cyclotron with a length of 60 kilometers.

These two beams of high-energy particles, after hitting each other at a speed close to the speed of light, produce energy that can cause an energy electron of 500 billion electron volts to shatter together with a positron, thus producing the Higgs particle.

And at this moment, the large hadron collider with this 60-kilometer circular tunnel is lying quietly in this secret base where no one is around.

Han Feng looked at the Large Hadron Collider in front of him, which was completely silent, and roughly understood why the parties involved in the Starfire Project would be so generous to reveal this location to him.

It was precisely because of the complexity of restarting the small nuclear reactor and the chicken nature of the Large Hadron Collider after the outbreak of the apocalyptic virus that the participants of the Spark Project so readily gave him the location of this secret base located under the former site of Atomic City.

If other forces want to restart small nuclear reactors and get the Large Hadron Collider back into operation, it will be more difficult.

But for Unimog, which has a miniature nuclear reactor, this is not a very difficult task.

Han Feng directly commanded Wu Yuli and drove the Unimog RV to the right side of the Large Hadron Collider.

When the RV slowly stopped, Han Feng removed the interface of the energy pipeline installed on the Large Hadron Collider and originally connected to the small nuclear reactor, and connected this energy pipeline to the Unimog RV.

"Buzz ——!"

The Large Hadron Collider received the energy supplied by the Unimog RV and let out a soft sound, and the machine, which had long been out of operation, slowly began to restart as if it had been brought back to life.

And with the buzzing sound, the lights on the Hadron Collider also came back on, and the huge fuselage of the seven or eight floors also let out a roar.

"Luckily, I only need to restart the LHC, and I don't need to analyze specific data." Han Feng looked at the dense buttons on the side of the Large Hadron Collider, and he was also dizzy.

It took him about four or five minutes to find a red button labeled 'Start' from the dense mass of buttons.

"It's up to you to win or lose this time."

After Han Feng took a deep breath, he directly pressed the red start button.

"Buzz——! Buzz——! ”

When the red start button was pressed, the roar inside the Large Hadron Collider rang countless times louder than before, and it was obvious that this huge machine seven or eight stories high had been fully activated and entered a working state.

With the LHC activated, two beams of high-energy particles were simultaneously ejected from the LHC's particle emission channel.

These two high-energy particle beams are shot out and enter the corresponding particle beam tube, and the superconducting magnet near the beam tube creates a super strong magnetic field, so that the high-energy particle beam continuously accelerates around the beam tube.

At the same time, the liquid nitrogen system in the cyclotron is also started synchronously, and the ultra-low temperature of minus 271 degrees Celsius continuously cools the corresponding magnets, so that these magnets remain superconductive.

When the Large Hadron Collider was successfully activated, Han Feng quietly returned to the Unimog RV, and now all he could do was wait quietly.

Although the two beams of high-energy particles in the cyclotron can walk more than 5,000 times per second in a cyclotron with a length of 60 kilometers, the probability of the collision of these two beams of high-energy particles in each revolution is like two toothpicks distributed in a vast space of 10 kilometers, and the probability of collision is very small.

The Large Hadron Collider can only rely on the high-energy particle beam to circle one by one, constantly circling in the cyclotron, and through the accumulation of countless numbers, to trigger two high-energy particle beams, which is very unlikely to collide.

Wu Yuli, who was originally staying in the Unimog RV, returned to the passenger seat and sat still after seeing Han Feng start the huge machine in front of him.

She could only turn her head and ask in a low voice, "Is there anything we need to do now?" ”

Han Feng, who was sitting in the passenger seat, raised his head, glanced at Wu Yuli beside him, and only said one word in his mouth: "Wait!" ”

As time slowly passed, Han Feng and Wu Yuli had already enjoyed two dinners in this secret base under the former site of Atomic City.

The large hadron collider in front of them still made a 'buzzing' sound, and in the cyclotron, the two beams of high-energy particles were still like two parallel lines that could never meet, and it seemed that there was no possibility of collision at all.

But just as Han Feng closed his eyes again and was about to rest, the long-lost electronic sound in his mind sounded again.

"Higgs particles have been detected, the mechanical core has completed the capture of the Higgs particles, the mechanical core breakthrough task has been completed, the mechanical core level is being upgraded, and the countdown is sixty minutes, during which the fusion of the mechanical core cannot be used by the Unimog RV."

"It's taking longer to raise the level of the mechanical core this time." Han Feng learned from the electronic voice that he didn't have any emotion, and after learning that the mechanical core upgrade time had reached sixty minutes, he first sighed, and then set his eyes on Wu Yuli, who was sleeping on a small bed.

Although Wu Yuli said that she could hand over this life to Han Feng at any time.

But for the major secret of the mechanical core upgrade, Han Feng decided not to let Wu Yuli know about it for the time being.

His ghostly figure instantly appeared at the head of Wu Yuli's bed, and pressed on the major artery in the sleeping Wu Yuli's neck.

After the major artery was pressed, Wu Yuli naturally fainted without a trace of consciousness.

When Han Feng hugged Wu Yuli, who had fainted, and took down the Unimog RV, the upgrade of the mechanical core officially began.
