In front of the gate leading to the fourth floor of the tower, Xiu Yi was carefully observing the pattern of the hexagram array on the gate.

This hexagram array is the most complex star array Xiu Yi has ever seen, and no one knows what it does.

Xiuyi hopes to study the significance and function of its existence.

Xiu Yi didn't know how his predecessors treated him here, but he was used to planning and then acting, so he had his own idea of ​​cracking laboratory secrets.

Because he owned an Electrotri laboratory, Xiuyi knew Electrotri much more than other alchemists. In Xiuyi's view, Electrotri is a typical and authentic alchemist. He doesn't care about anything else and just wants to pursue the ultimate of alchemy. Similarly, Electrotri is not a stingy person. Since he is willing to leave the laboratory, or even leave works such as magic puppet assistants, experimental notes, and Vajra puppets in the Valley Laboratory, it means that he does not mind letting future generations learn about his creations.

But in this case, Electra still set up some problems for future generations to solve, such as the demon rat, and the gate-opening magic array on the laboratory gate.

This can only show one thing. While Electret left behind alchemy for future generations, he also chose to inherit these things. Those who did not pass his test were not qualified to be his laboratory heirs.

Perhaps many people can understand this, but they regard breaking into the tower itself as a test.

Xiu Yi didn't think so.

It is not Electra's style to have death or not to live, and there are obvious clues for future generations to inquire and crack. This is the demeanor that a legendary alchemist should have.

Where is the clue?

Actually, it's right in front of you.

The architectural structure that is not allowed to be destroyed means that the castle contains a defensive formation, and the castle itself is an integral part of the formation.

This is a clue.

What does the hexagram array pattern leading to the fourth level represent? Is it related to the defensive magic array?

This is also a clue.

Electra left enough clues for future generations to crack before entering the fourth floor of the tower, but obviously most people ignored these elements and chose to forge ahead. Then the consequences would naturally be that they would disappear from now on.

Hines obviously saw some problems, so he chose to rebuild the Mist Hidden Castle on Purgatory Island, perhaps just to analyze the components of the formation in terms of the architectural pattern, but he did not succeed.

Perhaps he also studied this hexagram magic array, but he was unable to find the meaning and function of its existence.

So he didn't dare to go in. He knew that he couldn't even pass the initial test, let alone the straight to the tower behind him.

For Xiu Yi, these two clues were also something he had to crack, otherwise he would die if he went in!

When Xiyi felt regretful, there was no record of this in the notes he had received about Electra. Moreover, the layout here is also the most powerful defense system left by Electra so far, and its strength may be equivalent to the magic circle on Purgatory Island that trapped the magic dragon Rita.

When he thought of the demon dragon Rita, a trace of inspiration suddenly flashed in Xiuyi's mind, as if he had missed something.

"No, there must be something missing." Xiuyi said to himself.

Facing this legendary alchemy, Xiu Yi suddenly found that his always effective brain seemed to be unable to operate. Countless information about Electra flashed in his mind, and all the things, technology, and all the things related to him were restored to his mind one by one.

I have to say that Xiu Yi is lucky, because in the current world, the only alchemist who knows the most about Electrotri is probably Xiu Yi. He owns three notebooks of Electrotri and a laboratory, and knows two important connections with Electrotri.

However, even so, Xiu Yi still couldn't remember what he had missed.

"What did I forget?!" Xiu Yi was a little anxious.

It seemed as if he was standing before cracking the secret door of Electra, but he could not find the key.

Xu rarely saw Xiu Yi like this. He rushed over and bit Xiu Yi's trouser legs and pulled Xiu Yi desperately.

Even the flaming birds flying in the sky swooped over and landed on Xiuyi, awakening Xiuyi's sleeping memory with a crisp chirping.

Xiu Yi stared at Xu's anxious look for him in a daze, then turned around and looked at the six-pointed star magic array, and suddenly realized something in his heart.

"Oh my god, Xu, this is the magic circle that traps your mother! It is just smaller than the magic circle on Purgatory Island, so I couldn't recognize it at once! This is a magic circle that traps beasts! I remembered that Electra has the habit of using monsters to guard the laboratory! Do you remember? Xu, he used your mother to guard the portal and used demon rats to guard the valley laboratory!"

Xiu Yi pointed with one hand behind the door: "Behind this door, there must be a high-level monster inside! I don't know what mechanisms there are other than this, but just such a monster is probably enough to make all the alchemists who trespass in and die!"

"Woo!" Xu let out a thrilling low voice.

Xu felt scared from the bottom of his heart about the magic circle that trapped his mother.

In that valley laboratory, Electra did not use this magic town and trapped the demon rat in the valley, while the demon dragon Rita was imprisoned by a large beast trapping magic array.

From this perspective, the monster that guards the tower for Electra must be far superior to the monster rat in terms of strength, but is inferior to the demon dragon. It is very likely to be a top monster of level 11 or level 12.

This is already the strongest man in humans except the sacred realm.

"Don't worry, Xu." Xiuyi picked up the little guy: "As long as you don't go in, you won't be in trouble. But I'm sure that there are no monsters in it, otherwise even if the people who enter cannot beat it, at least some people should be able to escape. Since they have gone in, there is no one coming out, which means there is a maze inside. As long as you step into this door, you will lose your direction from now on, so no one can escape... No, no, someone has escaped."

Xiu Yi suddenly remembered what the butler said.

Someone once left the tower, but he went crazy.

Why can a lunatic leave?

Could it be... Another answer appeared in Xiu Yi's mind.

"It's a soul-like maze!" He said this sentence almost very surely.

Because only he knows that in addition to the well-known identity of the Alchemist, Electra also has another identity, namely the Soul Mage.

Even the Spirit-Devouring Ring was discovered from Electra's relics.

In this high tower, Electra first used a castle to create an external defensive magic circle, then used the magic circle that trapped the magic dragon Rita to trap a high-level monster, and then placed an existence in a soul-like maze.

This is the most tightly defended laboratory in Electra that Shuyi has seen. Of course, this may also be related to the fact that the laboratory itself is not secretive, so it can only strengthen its defense.

However, even so, Xiu Yi still felt a strong curiosity in his heart. He wanted to know what kind of alchemy technology Electra would put in this laboratory?

After thinking for a while, Xiu Yi said to Xu: "I hope there will be a way to untie your mother's constraints, and I also hope to get some better alchemy. The two obstacles we know in this door are not a problem for me. The eleventh level monster is not a black warrior, and I have the confidence to solve the problem. As for the soul maze, we have already broken through it once, and there will be no suspense after the second time. The problem is that the tower has been blocked for four floors. Does this mean that Electra has arranged four dangerous mechanisms here? What are the other two mechanisms? We don't know, and we can't force it. So it seems that we still have to find a cracking method from the outside before we can truly enter. Of course, I'm sure that it's not easy, but no matter how difficult this is, I believe that we are all closer to this secret than any alchemist who has entered here before..."

Speaking of this, Xiuyi smiled: "Look, our starting point is higher than others, so there is no need to worry about anything, right?"

A burst of blue smoke flashed, and Xu, whom Xiuyi was holding, transformed into the appearance of a little boy again.

The little guy hugged Xiuyi's neck: "Dad, can you really save your mom?"

"Yes, I will definitely try my best to rescue her." Xiuyi replied sincerely: "I don't have the strength yet, but maybe after opening this laboratory, I can find a way to crack that big array."

The little guy smiled happily. He kissed Xiuyi hard on the face and snuggled in Xiuyi's arms.

With the ability to transform into human forms, the little guy's intelligence is constantly improving.

For him, perhaps nothing more important could make his mother free again.

He has always envied little Paddy because he has a mother who loves him. Many times, the little guy will feel sour when he sees Paddy lying in Nancy's arms and giggling by his mother, and his heart will be sour, envious and jealous.

And now, Xiuyi gave him a promise.

Maybe it won't take long before Rita will be free.

"I not only want to rescue your mother, but also give you the ability to fly again." For some reason, Xiu Yi suddenly felt extremely confident.

He believed that he could definitely crack the secret here!

Because he is the only one who knows Electra the best.

"We start with the defensive array inside the castle, which is likely to be related to other mechanisms that we have not discovered yet," said Xiu Yi.

It is quite troublesome to find the defensive array inside the castle.

It's really crazy that you know that it exists, and it's here, and it works all the time, but you can't find where it is.

There were many alchemists who tried to start from the outside of the castle and use various methods to test the castle, but without exception, as long as they dared to attack any main building part of the castle, the magic circle would generate an attack.

Xiu Yi once used a captured monster to conduct an experiment and instructed it to destroy a certain city wall.

As a result, when the thick and thick lightning in the sky struck down, it was like a level seventh-level thunder magic falling straight into the sky.

The monster was split into a ball of powder, and a terrible charred pit appeared on the flat ground.

Faced with such an attack, Xiu Yi could only smile bitterly.

The power of this defensive castle that Electra made is too perverted.

With super attack power and super hidden ability, Xiu Yi is almost certain that the true defense ability of this magic array itself should be very low. No magic array is invincible, it only depends on whether you can find its weaknesses. So as long as you find the hidden position of the magic array, Xiu Yi is confident that he can easily destroy it.

In addition, Xiu Yi was very puzzled that such a powerful magic array was obviously not comparable to the one in the Valley Laboratory's activation magic array. So why can such a powerful magic array last for hundreds of years?

Where does its energy supply come from?

There are so many secrets about Electra. There are so many things to do, but I don’t know where to start.

Xiu Yi was busy for several days, but he couldn't figure it out. Apart from killing some monsters and allowing the fortress servants to witness the thrilling lightning strikes again and again, and more careful in his work, Xiu Yi gained nothing.

It was Christine, and there was a new way to threaten the lazy servants: "If you don't work hard, I'll use you to hit the wall!"

During this period, the dance party organized by Barkler and Christine and others was about to begin.

Xiuyi could only give up his mind for the time being and concentrate on preparing for the dance.

In addition, he also needs to find a way to solve the problem of Earl of Weston.

To kill Earl of Weston, Shue Glair must come forward. So when is this better position to come forward?

When Xiu Yi thought of returning to his original face to kill someone, he remembered Rasher. For some reason, this time Xiu Yi always felt uneasy in his heart.

Raschel's smiling face made Xiu Yi suddenly feel frightened for no reason.

Maybe it was a mistake to leave him alone? This was the first time Xiu Yi had this idea.

Since coming to Winlington, Shuyi has never felt such a strong sense of crisis, but he does not know where the crisis comes from.

In the evening, the carriage slowly entered the outskirts of Winlington.
