"McLean?" said halber, standing on the top of the tower and gently pressing Harry's shoulder. "I find it necessary for me to ask you a question first -"

As he spoke, he raised his empty arm and spread his hand slightly towards the spiral town below.

"Where have all the people in this town... Gone?"

It's not surprising that Haier Bo has such doubts, because although he doesn't seem to be very interested in spiral Town, he is actually "listening" to all kinds of actions and changes in the town all the time.

Therefore, when he personally entered spiral town and found that the facts were quite different from what he knew, he would naturally be surprised and surprised.

As for the specific means by which Haier Bo pays attention to the situation in spiral town and where the gap between the reality and the situation he knows comes from, we should start with the message that Hermione and Ron received from Maka in the temporary house not long ago.

Although Maka's preparation for this is obviously much earlier than that.

……

"Ron, what does it say?"

Just as the dust in the temporary house suddenly turned into a human shape and handed them a thin paper, Hermione on the stretcher couldn't help but stand up and ask.

"Well," said Ron, staring at what was on the paper, was it just to send everyone away from halber's eyes in the most sure way? No, if so, why did you let everyone come here to take refuge?

"Hermione?"

Seeing that she seemed to think of God alone on the stretcher, Ron waited for a while and finally couldn't help asking:

"Marca asked us to go to lupin after reading the note... Should we go?"

"Huh?"

When Hermione heard the speech, she came back from thinking. Then Ron saw her immediately wave her hand to the rear door.

"Sorry, I'm a little distracted... Let's go! We'll be there right away!"

Maka's plan is obviously cautious and complete - he separates the changes from time to time, and only let different executives know some of the actions each time.

For example, Delphi naturally didn't know the contents of the note between Hermione and Ron, but she was told by Marca to call them to a temporary house at a specific time;

For another example, when he changed the plan with lupin earlier, he mentioned that the spiral town should be ready to retreat at any time as soon as possible;

For another example, the entrance of the secret road is only clear to Delphi and Luna, who knows the details of the whole town in the mercury statue.

When all parts of the whole plan are gradually connected like this, we can piece together a complete action plan, so as not to expose one link and scrap all his plans.

When Ron took Hermione to the hall of the new Ministry of magic and informed lupin, the retreat became quite rapid due to Maka's prior warning. With the help of Luna in the mercury statue, all the asylum seekers left from the large secret evacuation channel hidden under the central square to the east coast.

The retreat was undoubtedly extremely thorough, including Kingsley and other combatants, as well as some key defenders in the plan, such as Hermione and Neville.

It can be said that Maka plans to leave most of the protective measures there after opening them.

However, those who still need to stay in the end naturally still exist. In addition to Marka herself, there are Harry who has been with him since he resisted the corpse army, Luna who needs to maintain two layers of magic shield... And Delphi who has been explicitly asked by Marka to stay in the observation room to confuse Haier's vision for the last time.

This time, Delphi, who had not been able to go to the front line to help eliminate the living corpses when necessary, finally seriously completed Maka's entrustment. Although... Even Maka doesn't know why she stayed in town and never took action.
