Technology should not exist here, Yun Fan is sure, at least he has never found any traces of technology at present.

Perhaps at most, it is a mechanical civilization, just like the village boat and village ship that can be produced in the Xiancun model, all of which belong to the category of mechanical civilization.

The difference is that the mechanical drive here is not fuel or energy, but Reiki, or energy of the same nature as Reiki.

However, most of the principles should be the same, and the appearance of this core alone gives Yun Fan a familiar feeling.

When Fu Bo saw Yun Fan's acquaintance, he asked in surprise, "Haven't you ever seen this thing?"

"I've never seen it!" Yun Fan replied dryly: "It's just that I've seen similar artifacts, and its appearance makes me feel a little familiar." ”

Fauber felt a glimmer of hope and asked expectantly, "Can you restore this thing to its original appearance?"

Yun Fan understood that what Fu Bo meant was to let this core have the ability to drive, simply put, to have kinetic energy, and only in this way could the entire Causeway Castle be able to operate again.

I didn't see the core before, but now I see it, Yun Fan can basically judge according to his guess that this core is similar to the body in our vehicle, and it is the foundation of the entire vehicle.

Fauber called it the core of the Causeway Castle, and this is what it always meant.

He still has a good impression of Fu Bo Yunfan, and Yun Fan will never forget the teachings he once had, the superficial imitation technique he learned. Although it is useless now, it at least broadens Yun Fan's horizons.

So, if you can. Yun Fan was willing to help Fu Bo.

As for the mysterious owner of the Causeway Castle, knowing that it was very powerful, Yun Fan also hoped that she could leave the Cifeng Continent as soon as possible, and staying here would always be a hidden danger.

Yun Fan can protect himself, but if he wants to protect the entire Sub-Peak Continent, he still doesn't have this ability at the moment.

There were many relatives, friends, and brothers on the Subpeak Continent, and it was impossible for Yun Fan to put them in danger.

In the face of Fauber's request. Yun Fan replied: "I'll try my best..."

"Then there is Lao Xiaoyou, if there is any need, just talk to me. Fauber smiled.

"I will!"

Afterwards. Yun Fan carefully studied the core of the Causeway Castle.

The four people present all looked at him, they were all wondering, why did Yun Fan look like he understood?

"Wouldn't it? Xiao San even knows this kind of thing?" Agni Huojun opened his mouth wide.

"It should be, look at the appearance of the junior. I should know a little bit. Danqing also said.

Wu You was a little reluctant to believe it. He has always been arrogant in his bones, always aiming for the best in his generation, it is difficult for him to accept the appearance of peers who are better than himself, and it is always difficult to give birth to a real good feeling in his heart.

I don't know what the mysterious gong owner said to Wu You, his face became even more ugly at the moment, and he looked worried.

Fu Bo waited with a kind face, no matter whether Yun Fan could finally repair the core of Causeway Castle, at least he would be grateful.

Ignoring Yun Fan, who didn't care about the reaction of the four. At the moment, I really put my heart and soul into it, as I slowly got to know it. Yun Fan seemed to have suddenly discovered something, which surprised him incomparably.

"How could it be this?Isn't that the dust map the route in the Causeway Castle?" Now Yun Fan learned that the dust map found in the underground tomb before was not a map of a labyrinth-like place at all, but a route map of the core in front of him.

The circuit at the core of Causeway Castle is not like the one we are familiar with, it is made of rare and precious materials, and it is a pipe for energy circulation.

The entire core relies on countless dense pipes of varying thicknesses to form a perfect cycle of energy, so that the entire core has kinetic energy.

It is no exaggeration to say that the core of Causeway Castle is the body of Causeway Castle, and Yun Fan understood.

No wonder Fu Bo and the others don't understand, they have never seen it, so naturally they can't understand the principle.

Seeing that Yun Fan seemed to have stopped researching, Fu Bo just asked, "Little friend, what's wrong?"

"Hmm...," Yun Fan pondered for a moment and said, "Maybe it's okay, but I need to find the key to its problem." I checked it carefully, and although the principle is not clear, I am at least sure that there is nothing wrong with the whole core, and the reason why it does not work is that there is something missing from it. ”

"What's missing?" Fu Bo asked, "I hope that Xiaoyou will observe carefully, for the sake of the three of you, and for the sake of the entire Sub-Peak Continent." ”

Fu Bo's words were not a threat, but a kind reminder, and it could be seen from this that if the mysterious gong master wanted to deal with Yun Fan and the three of them to slaughter the entire Sub-Peak Continent, Fu Bo was powerless to stop it.

Fauber is already extremely powerful, and you can imagine how powerful the mysterious gong owner is.

"Thank you Fubo for reminding me, Yun Fan understands. Yun Fan thanked him.

In the following time, Yun Fan began to look for the key to the inability of the core of the Causeway Castle, and according to his previous careful observation, the key to the decisive role should be very small, so small that it was difficult to find for a while.

But what could it be? Yun Fan thought about it and searched for it......

Time was passing quietly, and before I knew it, most of the day had passed, and Agni Huojun, who finally couldn't hold his breath, said to Danqing at this time: "I don't know what this thing is, can he really do it, junior?"

Danqing shook his head and said: "I don't know about this, anyway, I haven't seen it, maybe he has seen it in the outside world." ”

"I guess so," Agni Huo Jun thought too.

Only Fu Bo was surprised by Yun Fan's performance, as the steward of Causeway Castle, he was not a real life, but a life created by the art of imitation.

Although it is the same as human beings, there will always be some differences, it is better to have a cultivation realm that can never be improved, and without the influence of external forces, Fu Bo's existence is also eternal.

When Fauber was created, he was only responsible for a series of miscellaneous chores in Causeway Castle, and he was not responsible for maintaining the core of Causeway Castle, but the pseudo-creator who was responsible for maintaining the core of Causeway Castle is now long gone.

But Fauber had been in contact with him before, and he was able to understand some of it, and to know that someone could understand the core of Causeway Castle, which was quite remarkable.

Naturally, now Fu Bo is impressed with Yun Fan.

"Found it!" It took a whole day, until a few people lost hope until they lost hope, and Yun Fan's voice suddenly sounded.

"What is it?"

"What?"

Fu Bo and Agni Huo Jun all hurriedly gathered around, they were all curious, wondering what was wrong with the big guy they didn't understand at all.
