Since he couldn't protect the two of them at the same time, Yun Fan could only choose to protect Agni Huojun, after all, Danqing was still able to protect his life.

"Danqing protect yourself!" Yun Fan hurriedly shouted, and then defended with all his strength, and protected Agni Jun behind him.

"Okay, I got it. Danqing also understood the situation at this moment, and he hurriedly defended himself, trying his best to resist the impending shock wave.

"Little San, get out of the way, you won't be able to bear it. "Agni Huojun, who is protected behind him, doesn't want to see his good brother defend himself from harm, so he plans to stand up and share it with the two good brothers.

Because this impending shock wave has characteristics, only when more people face it together, will they share the power of the impact.

If Yun Fan blocked the Agni Jun behind him, then Yun Fan's damage would increase, and his power would directly double.

The power of the shock wave was already unbearable for Yun Fan, and this instantly doubled, and the final result can be imagined.

Rumble!

The speed of the shock wave was very fast, and in the blink of an eye, it was too late for Agni Jun to stand up and share the damage.

Poof!

The powerful attack raged by, Yun Fan and Danqing were both seriously injured and vomited blood, but Agni Huojun was not harmed at all because he was protected.

The two people who suffered the assault did not make the slightest concession, they would not let the owner of the Causeway Castle slaughter the Subpeak Continent.

"Little San, you let me ......" Agni Huojun's heart was full of throbbing, and he didn't know what to say. Yun Fan saved him again.

"There is no need to thank each other, if you can protect yourself, I definitely won't let you watch. Yun Fan forced himself to grin.

looked at the three brothers in front of him. Wu You was very surprised, he knew how terrible his master was, but he didn't expect that the three brothers would resist it, and none of them would be killed by bombardment.

Of course, Wu You also understood that this was just a random blow from the master, and he did not use all his strength.

"Yes, master!" said the owner of Causeway Castle again. Wu You, who learned about it, secretly replied, the communication between them was through the Causeway Castle, and outsiders naturally could not find out.

glanced at Yun Fan, who was seriously injured. Wu You sighed in his heart, compared to his master, the peak of the Immortal Immortal is really nothing, such a strong person who surpasses the world. It made Wu You unable to look up.

"The master has orders. Let the three of you follow me into Causeway Castle. Wu You suddenly spoke.

"Why?" the three Yun Fan brothers said they didn't understand, the owner of the Causeway Castle wanted to kill them, why did they let them in again in a blink of an eye?

"The master said, since the blow did not kill any of you, then give you a chance to survive, as long as you can find out the reason why the Causeway Castle cannot leave, the master will forgive you. Wu You said.

"Let's find out the reason?" Seeing that the two good brothers were injured, the unconvinced Agni said: "Isn't your master very powerful." Why should we find the reason? ”

Yun Fan stopped Agni Jun's anger, because no matter how Agni Jun complained. It's all ineffective, and in front of the real strong, the ants' resistance is just a joke.

Yun Fan had the power of nothingness, this was his strongest means of attack, and if it was time to fight hard, he wouldn't mind using this move with all his might inside the Causeway Castle.

"Okay, Wu You, take us in. Yun Fan agreed.

Wu You chuckled: "Fortunately, Yun Fan, you agreed, the master said, she won't give you a second chance." ”

"It's my luck..."Yun Fan said casually.

In desperation, in the face of the powerful and mysterious owner of Causeway Castle, the three Yunfan brothers could only enter first, and as for whether they could find the reason why Causeway Castle could not leave, it was difficult to draw conclusions now.

After entering the Causeway Castle, it has remained unchanged from beginning to end, and the closed rooms are like a real labyrinth.

Wu You reminded: "Don't run around, there are some places I can't go, once I get lost, I can't leave again." ”

Wu You's words are true, Yun Fan, who has been here before, naturally knows that this place is terrible, and the last time it wasn't for the housekeeper to appear, Yun Fan didn't know if he could go out in the end.

Thinking of the housekeeper of the Causeway Castle, Yun Fan asked, "I remember that there was a housekeeper in the Causeway Castle, how is he now?"

"Fu Bo, he's fine!" Wu You said.

Yun Fan asked again: "I remember that Fu Bo said that the previous master of Causeway Castle is dead, how can it be ...... now?"

"Before the master woke up, Fu Bo really thought that the previous master was dead, but the current master is not the previous master, you don't need to know these things, and the master will be unhappy if you talk too much. Wu You said.

Simply speaking, Yun Fan understood a little, but he couldn't know what was going on.

Since Wu You didn't want to say anything more, Yun Fan didn't continue to ask.

Under the leadership of Wu You, after passing through some closed rooms, several people arrived at the core of Causeway Castle, where Yun Fan met the butler he had seen.

"Fauber, it's been a long time since we met. After meeting, Yun Fan bowed respectfully.

Fu Bo is also a mysterious powerhouse, Yun Fan still can't see through him, but Fu Bo has long known about the arrival of Yun Fan's three brothers, so he is not so surprised to meet at this moment.

"In such a short period of time, your cultivation realm has been raised to such a level, not bad. Fauber said with a kind face.

Suddenly seeing the scene behind Fu Bo, Yun Fan was surprised, because as a traverser, he knew that the huge thing behind Fu Bo was obviously similar to a device like a machine.

Although there are slight differences in all aspects, the overall situation is still the same, and this is the first time Yun Fan has seen this kind of thing since he came to the other world.

For this reason, Yun Fan hurriedly asked: "Fu Bo, this is ......?"

Fauber stepped aside and said with a smile: "This is the core of Causeway Castle, I have been studying it since the master woke up, since Causeway Castle cannot be moved, I think there is a problem with this core." ”

"Fu Bo, can you let Yun Fan take a look?" Yun Fan took the initiative to request, because he was curious in his heart and wanted to find out.

"Of course you can!" said Fauber, "the master let you in, just so that you can come here to see the core." ”

Without speaking again, Yun Fan walked closer to the core, and he began to look carefully.

Danqing and Agni Huojun were also seeing such a strange thing for the first time, and they couldn't help but be curious, and they also began to look at it.

The whole core looks like it is made of bronze, but it is obviously not made of bronze, Yun Fan looked at it a little, and he was basically sure that the material used to make the core was an extremely rare and rare material, maybe even more precious than the immortal material.

What it was, Yun Fan couldn't know.

In addition to the extremely special material, the main component of the core is the gear, countless gears large and small, tightly interlocking with each other, at a glance, it looks like the inside of a watch.

"What the hell is this thing?" Yun Fan couldn't help but wonder.
