Gu Yijue was sweating coldly behind her. She thought of the beam of light that Li Ang had just released into the sky, and vaguely realized something, and subconsciously turned on the time backtrack.

A green light flashed, the crater cave disappeared, and the scene returned to the narrow and cramped basement.

The 2746th cycle begins here.

Raven, Dumbledore, and Man Man had already adapted to this cycle of death-living, and subconsciously gathered his magic power, intending to attack him.

After more than two thousand cycles, these mages have developed enough tacit understanding, and even don’t look at them. The slight magic fluctuations overlapping with each other are enough to convey information.

"We are becoming more and more familiar with this high-intensity battle. It is probably only a step away from defeating or even killing Li Ang."

The same message appeared in the hearts of the three, and there was also a joyful feeling.

However, the ancient priest on the other side of the basement had no intention of looking forward to victory. She was tense and was still thinking about what Li Ang said, "There is fate within the light cone."

"The beam of light you just released,"

Suddenly, Master Gu Yi raised his head and asked hard: "What is it?"

"It's a photon."

Li Ang explained with a smile: "More precisely, it is to separate a pair of entangled photons carrying information and release one of them onto the moon's quantum communication satellite.

This process is repeated at a certain number of times at high frequency, forming a series of photon strings."

Everyone looked at each other and was puzzled - they really couldn't understand these contents.

Fortunately, Raven, whose apparent identity is Prime Minister Rachel Ross, suddenly realized that among the British cabinet ministers held by the vampire, there was a minister of energy and climate change who was from a science and engineering department.

She released a spell casually, and the Minister of Energy and Climate, whose consciousness was taken away by the "heart-grabbing curse", immediately stood up and said mechanically according to the script: "The technology mentioned by Your Excellency Li Ang should come from the quantum stealth transmission solution, which is commonly known as quantum communication encryption technology.

Generally speaking, it is to divide a piece of information into two parts: classical information and quantum information, and it is transmitted to the recipient through classical channels and quantum channels.

Classic information is naturally traditional ordinary information, which uses traditional laser communication and is specifically responsible for transmitting the information ontology.

Quantum channels are more high-end and are not responsible for transmitting the content of the information ontology, but transmitting the measurement information of quantum states, that is, the password used to analyze the information.

To use quantum encryption technology, it is necessary to transfer the unknown quantum state of a certain particle to another place and prepare another particle to the quantum state, while the original particle remains far away.

According to Your Excellency Li Ang, he should send a series of single photons, and the receiver located on the moon measures the shape of these photons, and finally both sides obtain a random sequence.

Because a pair of photons has quantum entanglement properties, the random sequences or quantum keys obtained by both parties are exactly the same.

The unique randomness of the quantum key makes it unrelated to the ciphertext itself. According to the theory of Claude Shannon, the founder of information theory, ciphertexts encrypted using random number codes are absolutely impossible to crack even in mathematics.

For eavesdroppers, it is impossible to steal the information carried by the photon string, because Mr. Li Ang is sending a single photon string, and a single photon is the smallest unit of light and can no longer be divided down.

Coupled with the collapsed nature of quantum, the observations of the eavesdropper will change the quantum state, making it impossible for him to obtain the original key and resolve information based on the key.

Based on all the above conditions, the single-photon quantum state key transmission technology used by Your Excellency Li Ang is absolutely undecipherable - no matter how means, no matter how high the computing power is, it is impossible to decipher the quantum state key randomly generated according to Heisenberg's inaccurate principle."

After the Minister of Energy and Climate Change's explanation, everyone was still confused and could only turn their doubts to Li Ang.

"Haha, it's the 2,746 cycle now, right?"

Li Ang smiled and said, "At the end of the 2745th cycle, I released a single photon string to the moon. These photon strings established a light link with the memetic company's orbital plane of the moon. The communication distance is the average distance between the earth and the moon, which is 384,400 kilometers.

At this communication distance of 384,400 kilometers, the transmission efficiency of quantum keys is 20 orders of magnitude higher than that of the same terrestrial fiber channel, which is a multiplier of trillions.

The quantum deception state light source on quantum satellites sends 40 million model photons per second. One docking experiment can generate 300kbit security keys, with a code rate of up to 1.1kbps."

Everyone present could understand every word Li Ang said, but it seemed extremely awkward when combined.

"Tsk."

Li Ang curled his lips and said patiently: "In other words, I sent a large string of single photons to the quantum satellite on the orbit of the moon. I was worried that you might prevent or even tamper with the transmission of the photon string, but you don't know, so I was worried for nothing.

Anyway, these photon strings form keys in quantum satellites, and eventually point to a command."

Gu Yi suddenly realized something, and she said with difficulty: "...what instructions?"

Li Ang spread his hands and said, "The productivity of the Octopus Wisdom is so huge that I can do something I like to do - like building a military fortress deep in the moon's earth."

Gu Yi almost bit his lip and said in shock: "You want, fortress?"

"Yes, a fortress with the magic net system as a weapon." Li Ang said with a smile: "After receiving the quantum key, the moon fortress will start to operate. It will release a trace beam of high-energy particles. The moment it touches the London magic net, it will be strengthened by ether, increase the energy level, and tear the target place apart..."

Suddenly, he paused and said quickly: "The average distance between the earth and the moon is 384,400 kilometers, and the speed of light is 299792,458m/s, which means that it takes 1.28 seconds to transmit light from the moon to the ground."

As soon as the words fell, 1.28 seconds arrived.

Light, endless light.

The moon fortress released a beam of light that spanned 384,400 kilometers and hit the basement in the center of the London city of the British Isles in the North Sea.

Gu Yi didn't even snort, and was completely torn apart by a beam of high-energy particles.

Time retraces passively, and the green light flashes, and the basement returns to its original state.

However, before Gu Yi could gain a foothold, the 1.28 seconds had arrived again, and the beam of light came again.

Li Ang stood alone in the sky beam. His body was washed by the beam of high-energy particles, constantly ulcerating and cracking, and was quickly repaired by time.

The powerful body of the Jindan monk made Li Ang survive longer than others, so even if the ancient mage wanted to die together, he would not be able to do so.

"You lost."

Li Ang was washed by the beam of high-energy particles again and again, watching the green light on the Ancient One's body flashing, trying to trace back the time in vain, and laughed loudly: "It's useless, the speed of the photon string is almost the speed of light, so when the 2745th cycle, the photon string has exceeded the interference range of time backtracking.

In other words, the fact that the photon string is transmitted to the lunar base has become the past light cone of the 2,745 cycle.

If you follow the 2745th cycle and continue the plot, there is still a glimmer of hope.

However, when you go back to time and perform the 2746 cycle, the fact that the photon string is transmitted to the lunar base has become an impossible future light cone.

No matter if you perform the 2747 cycle or become the 2748th or 2749th cycle, you cannot rewrite the established time anchor point.

Beyond the light cone, everything is unknown, ignorant, and anxious.

Inside the light cone, everything is fate, and there is no escape, no escape."

Li Ang looked at Gu Yi who was still fighting with the trapped beasts and said calmly: "When you step into the light cone, you have lost the qualification to fight for your destiny."

Gu Yi was speechless, and the 1.28-second cycle of high-energy particle beams were constantly destroying her, while Ago Motorcycle Eye was constantly repairing her.

In her perception, the world line continues to close, symbolizing that the endless future is dying, and everything is heading towards its established destiny.

Number of world lines: 98413579813

Number of world lines: 841613246

Number of world lines: 15613

Number of world lines: 952

Number of world lines: 2

Only the last two possibilities remain, and the world line will be integrated into one immediately, and the Eye of Ago Motorcycle can no longer reveal other possibilities.

"I lost."

Ancient One, who was constantly melting in the light column, said the last sentence with difficulty, "Please defend this planet..."

A green light flashes,

Number of world lines: 1

The figure of Gu Yi was gone in the basement that returned to its original state. Everyone looked at each other in confusion, not sure what was going on.

"The great way is fifty, the sky is four nine, and the people escape one."

Li Ang walked forward with a silence, picked up the Ago motorcycle eye from where Gu Yi had just stood, and looked at it casually, "The secret of Minkovsky's time and space is clearly visible in front of my eyes."
