The plain cloud flag has two functions, one is to set up the array, and the other is to use the flag to collect people.

The enchantment is also a kind of formation, the enchantment of the isolation area, the layout is relatively simple, that is, to use mana to urge the flag, release the energy in the flag to envelop this area, and then form an isolation zone.

This is also the built-in function of the plain cloud flag, and it seems that its existence was born to arrange the barrier of the quarantine area.

Guan Yu's face was a little ugly, because he vaguely felt that something seemed wrong, so he released the black dragon.

"Do you know the origin of this plain cloud flag?" Guan Yu asked directly.

"Yes. The black dragon nodded and said: "The plain cloud realm flag is a supreme immortal weapon, it is one of the innate five flags, this flag is mainly to arrange the enchantment, the appearance of this flag is the great war between the human race and the demon race, with this flag, the human race finally won the victory." ”

"So, if I take this flag out of this world, will the barrier below disappear?" Guan Yu pointed to the barrier on the island.

The black dragon nodded and said, "It will definitely disappear, the controllable range of the mana of the plain cloud realm banner is ninety thousand miles in diameter, and if it exceeds ninety thousand li, all the formation enchantments will immediately collapse." ”

"Ninety thousand miles!" Guan Yu took a deep breath, the diameter of the earth was only more than 12,000 kilometers, right? Therefore, the formation under the plain cloud realm flag, as long as it was within the range he covered, the enchantment would not dissipate.

However, once the plain cloud realm flag leaves the earth, then I am afraid that all the enchantments will collapse in an instant, and countless spirit beasts will destroy the earth at that time.

There is sweat left on Guan Yu's forehead, although this plain cloud flag is a treasure, it is also a hot potato.

"You go back first, I see. With a wave of his hand, Guan Yu took the black dragon into his body.

Jiulong is not in the plain Cloud Realm Banner now, but in his dantian, after all, Guan Yu released Jiulong from the Lock Dragon Pillar, and it is impossible for Jiulong to return to the Cloud Realm Banner's array eye lock dragon pillar.

"Forget it, since you can't take it away, then don't take it. Guan Yu turned around and flew back.

At dawn the next day, Guan Yu appeared in the compound of the Thunder Bureau, and Long Sihai was very curious when he heard that he was coming, so he ordered someone to take Guan Yu into his office.

"What's wrong?" Long Sihai became weird, didn't he say that Guan Yu went to the second quarantine area last night?

Guan Yu's wrist flipped, and with a triangular rough edge, the golden flag was slapped by him on Long Sihai's table.

Long Sihai paused for a moment, and then said suspiciously: "You send me a pennant?"

"You're a big man with a big brain. Guan Yu casually threw the plain cloud realm flag into Long Sihai's arms, and said: "This flag should be the legendary magic weapon of the immortal family, it cannot be destroyed by water and fire, and the enchantment of all the quarantine areas in the earth year is spread by this flag!"

"What?" Long Sihai jumped up all of a sudden, really fake.

Guan Yu nodded at him very seriously, and then Long Sihai grabbed the flag tightly and said, "Give it to me?"

"This flag can't leave the earth, and if it leaves the earth, all the quarantine enchantments will shatter in an instant!"

In fact, Guan Yu didn't know if it would collapse, but his intuition told him that this was a treasure to maintain the safety of the earth, and it was not appropriate for him to take it away, if it really collapsed, it would be a sinner through the ages!

"Will it collapse when you get out of the earth enchantment?" Long Sihai glared in shock: "Then what are you doing for me." ”

"Because I don't know when I'm leaving, you can keep this flag, and if the quarantine barrier is broken somewhere, you can rearrange the barrier with this flag in hand. ”

"How?" asked Long Sihai.

"Of course, there is a law, and if you don't follow the law, you can't break it. "Guan Yu has already refined this flag, so it is impossible for others to destroy this flag and use it, but if you use the law in this flag, you can also use it, but the power is not so great.

Guan Yu picked up the pen and paper, wrote out the decision, pushed it in front of Long Sihai and said: "This decision, you write it down first, don't tell anyone else, after you write it down, burn the paper, and yes, this flag is my magic weapon, and I recognize me as the master, so when I come back, I will sense his location!"

"Do you really want to leave?" Long Sihai said while rote memorizing, and after reading it twice, his fingertips flicked it, and the whole paper was shattered.

"I have to go, even if I don't go now, I will go in the future, my mother is over there, and the way to find Rou'er must go from that side. Guan Yu stood up, thought for a while, and said, "If you also leave the earth one day, then give this flag to someone worthy of your trust!"

"Understood, rest assured. Long Sihai nodded heavily.

"Gone. After Guan Yu finished speaking, he turned around and left.

Long Sihai didn't send him, but held the flag tightly and didn't let go, and even he found that his palms were sweaty, because the flag was too heavy and too important.

......

And Guan Yu, who came to the second quarantine area again, escaped directly from a high altitude, stood on the highest mountain of the island, and released his divine thoughts!

"Huh~" In an instant, his divine thoughts shrouded the entire quarantine area, and now his divine thoughts are nearly six thousand meters, and the diameter of the island is not yet six thousand meters, so at this moment, everything on the island is in his sight!

However, there were no humans on the island, and he saw many snakes, many poisonous bees, and he had all explored the river and the ground, but there was no one.

Guan Yu slowly opened his eyes, Bai Xiaoliu was not there, but he entered here, so where did he hide? Or did he really go to another world.

"Number one, you can also help me check it out. Guan Yu said lightly.

"According to the internal information of the Thunder Bureau, Bai Xiaoliu did enter here and did not go out, and now that there is no one on the island, he should have entered the passage here. ”

"Did you go in?" Guan Yu took a deep breath: "Are you sure, don't let us go in then, but Bai Xiaoliu didn't go in, then it's bad." ”

"Can't confirm. Number One replied.

Guan Yu opened his mouth, he couldn't confirm it, but except for a huge sinkhole in the middle of the island that he couldn't explore, there was no hidden space in other places, because he could see it clearly in his thoughts, so he ...... If Bai Xiaoliu really came here, he would definitely enter the sinkhole, and I'm afraid that the pit is also a passage!

At this time, Guan Yu needs to decide, whether to continue the investigation, or go back and wait and see?

Guan Yu glanced back at the sea in the distance, there was a ferry sailing on the sea, and there seemed to be an airplane training in the sky.

But then, Guan Yu's gaze became firm again, his mother was over there, and he had to go from that side to find Rou'er, what else in this world did he have nostalgia for?

Although he didn't know if he would be able to come back in his lifetime, he ...... He had to go.

Guan Yu is not staying, since he has decided, he will not regret it!

"Whoosh~" He flew towards the core area in the center of the island, where huge sinkholes, sinkholes smashed by meteor showers, and the sinkholes are the passage to another world.

What kind of world would that be?
