The Gathering Array is like an accelerator, and with its own mana drain, it is even faster.

Chuan Qidao smiled and said, "Haha, I also look forward to your successful improvement!" After all, it's been a long time since the spell world has had this kind of open mind! ”

"The times are advancing, and we can't rest on our laurels!" Zhang Xuan said with a smile.

He has been a human being for several generations, although his martial arts can be regarded as the world's first-class, but he still needs to develop science and technology according to the trend of history.

After all, the power of one person is too small, and only by combining the power of thousands of people can the world progress.

The world of Harry Potter is a lonely magical world that will inevitably be occupied by technology in the future.

Now Zhang Xuan is improving magic, and when he has studied it thoroughly, he will start to combine magic with technology, combining two by two, although the power is not necessarily as great as the atomic bomb, but it will definitely be very convenient.

Chen Tienan said: "It's almost time, we should go back!" ”

Zhang Xuan also reacted, and this exchange was already in the afternoon.

"So soon, I still feel like I can't get enough!" Zhang Xuan said regretfully: "Next time I will come to visit Xuanwu Palace again!" ”

Chuan Qidao said: "I'm looking forward to it too!" Little brother, you are so insightful at such a young age, I also have a sense of bosom friend! ”

After saying goodbye to the Seven Daoists, Zhang Xuan followed Chen Tienan to leave by boat, and returned home just to eat.

At night, Zhang Xuan took out the Seven Ways of Gathering Spirit Array and put it in front of him.

"This Xuanwu Palace is not far from the capital, and it seems that it is also secretly protecting the motherland, although Chen Tienan is not too powerful, but they rely on the organization, and they know a little bit about the leopard in the tube!" Zhang Xuanxin said.

"I really don't know what it's like when a spell fights with a person, whether it's holding a spell or casting a spell with a peachwood sword? Or just use the palm of your hand? However, there doesn't seem to be a spell that summons thunder and lightning in magic! ”

"The Five Ghost Handling Technique is similar to summoning a spell, and opening the Heavenly Eye is like opening an X-ray, and there doesn't seem to be such a convenient way to detect magic in the magic!"

"The wizarding world has a high concentration of magic power, but it is just a super large enchantment, and there are no Muggles in it, so the magic concentration is a little higher, but the Four Elephant Spirit Gathering Array is a higher level, and it can absorb the magic power of heaven and earth!"

The Wizarding World Enchantment can block the flow of magic, so why go one step further and absorb the magic of the outside world?

Zhang Xuan couldn't figure this out. "If you can't figure it out, then don't think about it, let's take a look at the Spirit Gathering Array first!"

This is Zhang Xuan's mistake, just because the wizard world is too large, if you arrange an enchantment to absorb magic power, I don't know how much material it will cost!

Moreover, the population of the wizarding world is not large, and there are many magical plants and magical creatures in it, as long as the circulation of magic power is isolated, the concentration of magic power in the magic world will increase little by little.

Zhang Xuan first picked up the formation of the Four Elephants Gathering Spirit Array to explain in detail, the Four Elephants Gathering Spirit Array is to absorb spiritual power with the four divine beasts as the spirit, after arranging the magic array, the tail of the four flags will be in the direction of the middle of the disk, and the disk forms a spiritual power circuit.

Of course, the first thing is to apply spiritual power to the four array flags and discs, let them run first, and then leave it alone, it will automatically absorb spiritual power.

Zhang Xuan watched it for a long time, and then discovered the principle of the Four Elephants Gathering Spirit Array.

There is also a limit to the amount of aura that this spirit gathering array can absorb, that is, the capacity of the disc exceeds the limit that the disc can bear, and it cannot absorb the aura because it is already saturated.

And absorbing aura is not without consumption, because it is also unreasonable.

When I saw the maintenance of the magic weapon, I saw that it was written in the book that the formation would consume the cinnabar gold dust on the array flag, so it needed to be filled and maintained from time to time.

"I see!" Only then did Zhang Xuan fully understand the Spirit Gathering Array.

I looked at this small flag again, and there were small gold lines drawn on the flagpole, which converged on the flag, and the flag was painted with the green dragon and white tiger Xuanwu, which were also outlined with gold powder.

"It seems that the small gold thread on the flagpole is a suction mouth, which is gathered through gold dust cinnabar and introduced into the formation!" Zhang Xuan said with a smile and hurriedly set up a magic circle on the table.

It didn't take long for the circle to be in operation, and because the area was not large, the magic inside the circle was soon filled. But the concentration of magic power was much lower than Zhang Xuan expected.

"It's just over twice as much as the air, but it's still a lot lower than those magic materials! I'm afraid I won't be able to cast the spell directly! Zhang Xuanxin said.

"There is no problem with the principle of this Spirit Gathering Array, then the next step is to increase the spiritual power concentration of the Spirit Gathering Array!" Zhang Xuan muttered, and continued to think.

But now he doesn't have any magic materials around him, and he can't use them, so he can only come up with a few ideas first.

When I returned to the UK, my grandparents and grandparents followed.

"Good girl, this is the maid of the house!"

Grandpa looked at the Sebas who came to pick up the airport and exclaimed: "I thought you were bragging, but I didn't expect Zhang Weiguo to be a landlord in the UK!" ”

"Dad, I don't like to hear what you say, what is the landlord, I don't farm!" Zhang Weiguo smiled:

"What's the matter, I'm also a scholar, and it's normal to enjoy special treatment!"

"Mom and Dad, don't listen to Zhang Weiguo's nonsense!" Mother Li Chaomei smiled: "This is the elf raised by her son, and they are all stained with Zhang Xuan's light"

Several old people all looked at Zhang Xuan and said with a smile: "I didn't expect that a good grandson still has such a ability!" ”

"Didn't I pay for it?" Dad Zhang Weiguo muttered quietly.

Seven people and three cars, back home, Tony Dobby and others also hurriedly greeted.

Zhang Weiguo and Li Chaomei took a few old people to travel, and Zhang Xuan, the meat of his heart, naturally would not be let go, and he also accompanied several old people to play together.

Zhang Xuan's daily study and research time has been greatly reduced, and his progress has been slow.

It wasn't until after school started that Zhang Xuan returned to his normal life. Once inside the school, Hermione hurried over with a newspaper.

"Zhang Xuan, is that you in the photo? You're in the newspaper! Hermione said excitedly, "I didn't expect you to have a servant at home!" Oh, my God! I didn't expect you to be a nobleman! ”

Harry and Ron also looked at Zhang Xuan eagerly, and Ron said, "I don't care, I must go to your house to have fun!" I want a servant too! ”

Zhang Xuan took the newspaper and looked at it, and it turned out to be a photo of Sebas when he was picked up from the airport that day.

They were wearing housekeeper clothes and maid clothes, but they attracted the attention of reporters, and they heard that Zhang Xuan's family lived in the castle, so there was this report.

Luckily, it was a Muggle newspaper, so not many people knew about it.

"Yes, it's me!" Zhang Xuan took the newspaper and read it and said, "I didn't expect to be discovered by you after only taking a side picture of my face!" ”

"Hmph~" Hermione's face turned red, and Ron hurriedly said, "Are these maid castles real?" ”

Harry also looked at Zhang Xuan eagerly: "You've never said anything about it!" ”
