Hogwarts: Becoming a god from reselling fresh food

Chapter 418 The Law of Time Travel

The moment the red spear entered the atmosphere, Murphy sensed its existence through a sophisticated radar matrix.

After the spear was divided into three parts, he immediately calculated the landing points of the three spears.

Later, he activated the "Time Box" he brought with him and returned to five hours ago.

This is one of the plans that has been prepared in advance. Once the moon attack fails and there are signs that oneself may be hit, he must immediately go back to the past to prepare for possible hits.

This point in time backtracking is very important. He must confirm that his side has been hit, and at the same time, he must go back in time before the blow actually comes and causes losses.

It is necessary to confirm that one's own side has been attacked, naturally in order to obtain more information and know the possible attack methods, so that we can carry out targeted responses.

But "it must be before the strike comes" in order to avoid the "time observer effect".

The so-called "time observer effect" means that once an event is observed by any observer, then the event will definitely happen to the observer. No matter how it travels through the past, the occurrence of the event will be significant to the observation. Both will be inevitable.

In short, it is possible to use a time turner to go back in time, but a time traveler cannot change what has already happened.

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

Muggle scientists have observed and confirmed this phenomenon since the beginning of their research on time turners. It is called the "First Law of Time Travel."

Under this iron rule, if you see a person die in a car accident, then any attempt to go back in time and try to change this reality will not succeed. If you want to save a person who may die in a car accident, you must Back in time before the car actually killed him.

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

Any event that you can change through time travel is an event that you are not sure will happen in the end.

Once you know something is going to happen, you can't change it. You can only change it before it can happen.

Under this law, time travel is actually just a way to increase the probability of winning in some scenarios, and trial and error of loading files cannot be carried out.

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

However, the terrifying magic power on that spear was extraordinary. He almost immediately judged that it might have the power to destroy a city, and the London and Alkaim where it landed were not what he had recognized before. Even Zhizhong is unlikely to be able to defend against such an attack.

Moreover, the several pieces of information he just received also gave him some speculations about this matter.

If Jim Best was not deceived, then the person who gave him instructions might be his future self.

However, the highest management authority of the "Binary Tree" supercomputer cannot be broken at all. If people other than Murphy want to obtain the highest management authority, they first need to face a lattice password cracking problem. The difficulty of cracking is even impossible with a quantum computer. , if the "Unlocking Spell" is used to try to crack it, the magic power consumed is enough to create an earth out of thin air.

Therefore, the person who gave the order to attack was most likely Murphy himself.

This incident itself is a reminder that he needs to go back to the past: because the future self has indeed gone back to the past.

Murphy returned to five hours ago and left the combat command center.

The lunar operation plan has failed. This is a fact that has been observed. He cannot change it. Moreover, he has used almost all the resources for this plan. Even if he had to do it over again, he would not be able to do it better. There is therefore no point in retroactive intervention.

All he has to do is to prevent his own side from suffering heavy losses under the attack.

He first checked the situation of the "Binary Tree" and confirmed that it had not been invaded. Then he thought about it and prepared a command to send the combat machine to the landing point in Siberia.

Then he went to London, found the magic research team, and found that they were already making a "magic barrier".

Murphy asked a staff member and found that they started working on this work five hours ago. Since it was a sudden instruction and did not go through the normal project process, Murphy was unaware of it.

"In other words, it was not my time travel that gave them the instructions to make the magic barrier."

"Would I backtrack again?"

He learned about the so-called magic barrier, which is a magic technology that imitates Alkaim's "Holy Wall". The technical difficulty is not high. The most important thing is to connect the magic barrier to the magic network. With the magic network, The network is maintained by a steady stream of magic energy. In theory, unless the attacker uses more magic energy than the magic energy circulating in the nodes of the magic network, it will be impossible to break through it.

He had some confidence in his mind. This technique was obviously aimed at spear attacks.

Finally, he came to Alqaim.

At this moment, the Holy City of Wizards was decorated with lights and colorful lights, as if some grand celebration was being held.

As soon as Murphy appeared on Tian Street, several wizards gathered around him. A young wizard gave Murphy a bouquet of flowers and said, "Congratulations, Your Majesty the Great Shaman, and best wishes to you and Her Majesty the Queen."

All the way to the Palace of Spring, everyone was smiling at him, and when he finally saw the Queen, he understood the meaning of this smile.

Sophia was wearing a gorgeous dress robe and a gold ring on her left hand. She looked at Murphy with a smile, "Why are you back?"

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

The Queen raised her hand and spread her fingers to show him, "You gave it to me. We are engaged, Mr. Murphy."

"..."

Murphy was speechless for a moment, what kind of evil self-NTR plot is this?

"Future me?"

Sophia nodded.

"You said 'again', I came back more than once today?"

Sophia nodded again.

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

In order to avoid the "observer effect", time travelers must minimize the amount of information received, so Murphy's problems are very simple.

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

Murphy felt relieved, "Is this what I told you in the future?"

"Yes. You reminded me to connect the holy wall to the magic network. That's probably why you came here this time, right?" the queen said.

Murphy was completely relieved.

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

Heaving a sigh of relief, Murphy looked at Sophia again, wondering why he came back to get engaged with the Queen today.

But it was a bit difficult to ask, and after confirming his own safety, he needed to go back and solve the remaining problems.

…

Sophia watched Murphy disappear in front of her, knowing that he had returned to the future a few hours later.

She gently rubbed the ring on her left hand.

She wasn't lying.

Alkaim is safe.

But she didn't tell the whole truth.

However, no matter what, the outcome is doomed.

This is a step she must complete, and at the same time, it is also her heartfelt choice.

Goodbye, Mr. Murphy.
