There was a fire dragon running around in Muggle City, which could not be too eye-catching, not to mention Harry. They went to heaven later.

Although Maka, who had just traced back for five hours, had restrained her ability to sense magic, coupled with the dense fog in the city, she still quietly searched for the past with the sound of fighting.

No way. After all, norbeta is a huge fire dragon. Just hitting the ground at the beginning is enough for people within miles to notice here.

In fact, the black pupil wizard who later attacked Harry came out suddenly.

At first, after Maka arrived at the block, he could not easily run out to help, but chose to hide in a building next to the street at the first time.

After he looked at the top of the staff again and confirmed that the stone ball was still unresponsive, he carefully observed the battle between Harry and Charlie.

If they succeed in defeating the two black pupil wizards, it's naturally good, and he won't interfere more pointlessly; But if they met any danger, it would be an opportunity for him to test the stone ball.

So, just when Harry and Charlie tacitly played "koboff's decoy", and finally Harry passed by with two black pupil wizards with a sharp sword in his hand, Maka even found the opportunity to test for the first time!

Yes, at that time, the speed of both sides had climbed to the limit, so fast that people couldn't see the situation when the three met.

Not even Harry, the client, was aware of it. When his Gryffindor sword flashed silver towards the waist and abdomen of one of the enemies, the black pupil wizard on the other side also silently extended a black thorn to him.

However, Harry didn't notice that Marca, who was quietly watching, saw it.

Before, at the gate of St. Mungo, Maka had a brief fight with the "same kind" of the black pupil wizard while dealing with Haier Bo.

On the premise of knowing the strength of the other side, it was obviously no problem for him to silently pull away the black thorn extending to Harry.

Well, maybe even if he didn't do it, Harry would only be scratched with a not very serious wound - the Quidditch tactics of Harry and Charlie were still very effective at that time. Although the black pupil wizard reluctantly reacted, it was still late.

However, this may not be a big deal for Harry, but it is very important for Marca.

At that moment, Marca's intervention made Harry, who should have been injured, only broke his clothes. This behavior undoubtedly changed things.

Changing the facts that have happened in the past will certainly make all kinds of big or small changes in the future. No one can predict what will happen.

However, not every possibility of change will lead to the amendment of the time rule.

In order to try to find out the specific limits and laws, Maka not only spent a lot of spirit to create Rune Stone Balls, but also kept experimenting with time converters. In that case, it seemed to be incidental that he finally secretly helped Harry.

Therefore, while secretly doing it, Maka's eyes didn't look carefully at the situation in the battle. He focused most of his attention on the stone ball at the top of the staff.

At that moment, he and my right hand clearly felt the slight vibration of the stone ball, and the red streamer on its surface fluctuated slightly.

"Effective! Indeed effective!"

Although it was only a very slight fluctuation and soon stabilized, Maka's expression was a little more undisguised joy.

With the first attempt to gain something, his heart that has been hanging slightly since he made the stone ball finally has a little sense of sureness.

After that, Marca soon pressed her heart again and refocused her eyes on Harry, who was still fighting.

A black pupil wizard was cut off from the air on the spot, which excited Harry and Charlie.

It can be said that at the beginning, Charlie's first reaction was to choose a temporary retreat when he found that the second enemy suddenly intervened. When he and Bill went out to search and rescue, he also met an enemy who could control unknown black matter. At that time, nobeta was also injured.

Although relying on the powerful resilience of the fire dragon, a small hole in the leg is not a big problem. But at that time, even if there were two powerful wizards, Charlie and bill, and a fire dragon failed to win each other, it could explain a lot of problems.

However, this time bill was replaced by Harry, and the battle situation was so different. When their tactical cooperation really worked, Charlie couldn't help sighing - he and bill had agreed to Harry's two-way proposal, which was really right.

In fact, just after Harry came out of the Quidditch Museum, he told him the proposal.

In fact, according to Harry's idea, he must give full play to the sharpness of Gryffindor's sword. But when he first fought side by side with Neville, he realized the importance of fighting with others.

Even if the number must not be too large, after all, the combat effectiveness of those black pupil wizards is amazing, but one or two tacit companions are still very necessary.

Therefore, he planned to let bill and Charlie come out alone and fight with more and more black pupil wizards in downtown London while searching and rescuing with him; The remaining one went to the Leaky Cauldron bar and asked for more people to add search and rescue personnel for their third escape difficulty.

Finally, after learning that even Marca and Kingsley recognized Harry's strength, Charlie finally agreed to Harry's proposal.

"He's running! Charlie, chase!"

Just as Charlie was feeling secretly and wanted to solve the remaining black pupil wizard with Harry, Harry suddenly shouted.

Of course Charlie saw it, but he hesitated a little whether to chase it or not. To be honest, compared with Harry, who consciously wants to help in cleaning the black pupil wizard, he actually prefers search and rescue operations after all.

But even so, after seeing Harry's cry, when he rushed out on his broom, Charlie patted norbeta under him and hurried forward.

Seeing that there was only one enemy left, Maka, who was hiding and watching, naturally wouldn't worry too much. Realizing that Harry should have no problem, he turned and left to find the next object for him to test.

……

Fighting continued throughout London.

A large number of wizards and Muggle troops led by Sirius and Kingsley fought a large-scale war with the "crazy congregation" controlled by hairbo;

Some elite Aurors led their own teams to have a small-scale collision with the scattered small groups of black wizards;

There are even some wizard people who do not belong to any power at all, but have some strength. They are also emerging in the streets through the gradually thick night, fighting with sporadic crazy wizards.

Although it was already night, the war in London was more vigorous than during the day. Because now anyone with a little brain and some understanding of the current situation can see that Haier Bo is going to wash the city of London!

When people are in danger, who can easily stay out of the fog area except those on the edge?

Because of this, Maka's test objects are everywhere. You can meet all kinds of opportunities if you walk around.

However, the objects with real test value are not so easy to choose.

There are examples of success in avoiding Harry's injury. Next, he needs a change that can better affect the future. On this basis, he should carefully consider the degree of intervention and should not exceed the unknown "limit".

"Huh?"

Maka, who was keeping invisible and walking quietly in the street, suddenly frowned slightly. Because at that moment, he seemed to catch a glimpse of a deja vu face peeking from the window of a house on the street.

Because the curtains inside were half closed and there was no light in the room, except him, an Auror team fighting in the street did not find another person peeping in the next room.

After stopping and thinking for a while, although Marca could feel the familiarity that the face brought to her, she didn't remember who the other party was for a while.

"I should have seen it somewhere, but it doesn't matter, so I can't remember it for a while."

After such hesitation, Maka glanced around and decided to get closer and have a closer look.

Naturally, not everyone can see through his stealth magic. All the way through the street where the fierce battle was taking place. When he quietly stood in front of the window, the other party could face him almost as soon as he bowed his head, but he still didn't notice any abnormality.

Outside the window, Maka looked directly at the middle-aged man's face for a while. After a moment, she seemed to pick her eyebrows suddenly.

Yes, although he met each other a few times and the man was really insignificant, he still found something from the corner of his memory.

"Is this man... The father of NES Taron?"

Ernst was the student who Marka personally guided and led into Hogwarts, so he still remembered that child very clearly. At present, the little guy also left the school with the study tour team to calculate the time and itinerary. At this time, he should increase his knowledge in the waters near South America!

But his father, Marca, doesn't remember very well... He only remembers that the man seems to be a squib and has a particularly bad temper.

"Shouldn't Ernst's house be next door to Fisher's?"

When little Delphi was foster there by Marca, he also sat at Ernst's house, which he must remember correctly.
