Hogwarts: From Selling White Peppers to Becoming a God

Chapter 418 The Laws of Time Travel

The moment the crimson spear entered the atmosphere, Murphy detected its presence through a sophisticated radar matrix.

After the spear split into three, he immediately calculated the landing points of the three spears.

He then activated the "Time Box" he carried with him and returned to five hours earlier.

This was one of the plans prepared in advance. If the lunar attack failed and there were signs that his side might be attacked, he would have to immediately go back in time to prepare for the possible attack.

The timing of this time reversal is crucial; it must be done before it is confirmed that one's side has been attacked, and before the attack actually occurs and causes damage.

The need to confirm that one's own side has been attacked is naturally for the purpose of obtaining more information. Only by knowing the possible methods of attack can one take targeted countermeasures.

However, the requirement to "before the attack" is to avoid the "time observer effect."

The so-called "time observer effect" means that once an event is observed by any observer, then for that observer, the event has undoubtedly occurred, regardless of how time travels back in time; the occurrence of the event will be inevitable for that observer.

In short, it is possible to go back to the past using a time converter, but a time traveler cannot change what has already happened.

In other words, future events are in fact the result of the influence of time travelers.

Muggle scientists observed and confirmed this phenomenon when they first started researching time converters; it is known as the "First Law of Time Travel".

Under this ironclad rule, if you see someone die in a car accident, any attempt to go back in time to change that reality will be unsuccessful. To save someone who might die in a car accident, you must go back in time before the car actually hits and kills them.

This leads to the second law of time travel: the law of incomplete information.

Any event that you can change through time travel is one that you are unsure whether it will ultimately happen.

Once you've confirmed that something will happen, you can't change it; you can only change it before it might happen.

Under this rule, time travel in certain scenarios is actually just a way to increase the chances of winning, and it does not allow for trial and error by reloading save files.

The timing and manner of its use are also very subtle. Sometimes its tactical effect is almost the same as "time stop" and "time acceleration", so Murphy usually does not use this method often.

However, the surging and terrifying magic power on that spear was extraordinary. He almost immediately judged that it might have the power to destroy a city, and in his previous understanding, London and Al-Kaim, where it was to land, were unlikely to be able to defend against such an attack.

Moreover, the messages he had just received had given him some ideas about the matter.

If Jim Best wasn't deceived, then the person who gave him the instructions might have been his future self.

However, the highest management authority of the "Binary Tree" supercomputer is impossible to break. Anyone other than Murphy who wants to obtain the highest management authority must first face the problem of cracking a lattice password. The difficulty of cracking it is such that even a quantum computer cannot complete it. If one tries to crack it with the "unlocking spell", the magical power consumed is enough to create an Earth out of thin air.

Therefore, it is highly likely that Murphy himself was the one who issued the order to attack.

This event itself is a hint that he needs to go back to the past: because his future self did indeed go back to the past.

Murphy went back to five hours earlier and left the operations command center.

The lunar operation has failed; this is an observable fact that he cannot change. Moreover, he has already used almost all the resources for this plan, and even if he could do it again, he could not do it any better. Therefore, there is no point in retrospective intervention.

All he had to do was avoid suffering significant losses under attack.

He first checked the status of the "binary tree" to confirm that it had not been invaded. Then, after thinking for a moment, he prepared a command to send the combat machine to the Siberian landing point.

He then went to London and found the Magic Research Group, where he discovered that they were already working on the "Magic Barrier".

Murphy asked a staff member and found that they had started the work five hours earlier. Because it was a sudden instruction and did not go through the normal project process, Murphy was unaware of it.

"In other words, it wasn't me who gave them the instruction to create the magic barrier during this time travel."

"Will I go back in time again?"

He learned about the so-called magic barrier, a magic technology that imitated Alkaim's "Holy Wall." The technical difficulty was not high; the most important thing was to connect the magic barrier to the magic network and maintain it by relying on the continuous magic energy in the magic network. Theoretically, unless the attacker used more magic energy than the magic energy flowing in the nodes of the magic network, it would be impossible to break through it.

He had a better understanding of the situation; this technique was clearly designed to counter attacks with long spears.

Finally, he arrived in Al-Kaim.

At this moment, the Wizarding Holy City was brightly decorated, as if a grand celebration was taking place.

As soon as Murphy appeared on the Heavenly Street, several wizards surrounded him. One of the young wizards presented Murphy with a bouquet of flowers, saying, "Congratulations, Your Excellency the Great Shaman. Bless you and Her Majesty the Queen."

As he arrived at the Spring Palace, everyone greeted him with smiles, and when he finally met the Empress, he understood the meaning behind those smiles.

Sophia, dressed in a gorgeous gown and wearing a gold ring on her left hand, smiled at Murphy and asked, "Why are you back again?"

Murphy looked at the ring on the other person's left hand with a complicated expression. "Could this be...?"

The Queen raised her hand, spreading her fingers for him to see. "You gave it to me. We're engaged, Mr. Murphy."

"..."

Murphy was speechless for a moment. What kind of bizarre self-NTR plot was this?

"Me in the future?"

Sofia nodded.

"You said 'again,' but I've been back more than once today?"

Sofia nodded again.

"So you know why I came back this time, right?"

To avoid the "observer effect," time travelers need to minimize the amount of information they receive, so Murphy's problems are all quite simple.

The Queen thought for a moment and understood. "Is this your first time back? Then you must have come to warn me that the Holy City is in danger? But don't worry, Alkaim is safe."

Murphy felt a sense of relief. "Did my future self tell you this?"

"Yes. You reminded me to connect the Holy Wall to the Magic Network. You must have come here for that, right?" the Queen said.

Murphy was completely relieved.

In the future, he observed that Alkaim was not in danger and then told the Queen this fact. According to the time observer effect, Alkaim's safety was a confirmed fact that no one could change.

With a sigh of relief, Murphy looked at Sophia again, wondering why she had made a special trip back today to get engaged to the Queen.

But it was a difficult question to ask, and after confirming that his side was safe, he also needed to go back and deal with the remaining issues.

……

Sophia watched as Murphy disappeared before her eyes, knowing he had returned to the future, a few hours later.

She gently stroked the ring on her left hand.

She wasn't lying.

Al-Kaim is safe.

However, she did not tell the whole truth.

However, the outcome was already predetermined.

This was a step she had to take, but it was also a choice she made from the bottom of her heart.

Goodbye, Mr. Murphy.
