Following behind Lu Yan, Gu Yuan re-entered the small building.

However, this time, Lu Yan did not take Gu Yuan upstairs, but came to the front of the sand table.

This sand table, Gu Yuan had also seen it for a long time before, it was a bird's-eye view of the entire Star City, Gu Yuan grew up in Star City since he was a child, and when he saw such a sand table, he felt very fresh at first, and he could even find his own home on this sand table.

And I heard Lu Yan say that this sand table will be updated every six months, after all, the city is also changing.

"Lord Lu, is there anything special about this sand table?" Gu Yuan asked.

"That's natural, otherwise what are you doing here, is it just for viewing?" Lu Yan said with a smile, "This sand table is actually a magic weapon, which is jointly created by the formation master and the soldiers!" ”

"Oh?" Gu Yuan suddenly became interested, "What's the effect of that?" ”

"To put it simply, you can mark a location on the sandbox and quickly teleport there, but you can only use it three times a month." Lu Yan said, "So, do it and cherish it, I will give you the method." ”

Gu Yuan's eyes widened: "Teleportation array? ”

"It's not an exaggeration to say that, this formation is with the help of Star City's earth qi, so it can only play a role in Star City, and similarly, even if the sand table is made bigger, you can't teleport to the realm that doesn't belong to Star City." Lu Yan replied.

Gu Yuan's face was stunned.

"It's really...... Good stuff! ”

"That's natural, this kind of sand table can only be used by the sword-wielder, because every sword-wielder will have a city seal in his hand." Lu Yan said, "Remember, you can only use it three times a month, so don't use it unless necessary, lest you have no chance when you really need it." ”

Gu Yuan nodded hurriedly.

"Don't worry, Lord Lu, I remember!"

Then Gu Yuan said: "Our Great Xia's array masters and soldiers are really amazing, if this thing can be placed in Demon Slaying City, wouldn't it be able to play a very important role?" ”

"First of all, on the northern side of Xinjiang, there is still a part of the territory of the demon clan, and we have not been able to get the recognition of the earth's qi, and in addition, the city seal is made of a kind of extraterrestrial material, and it can't be made now." Lu Yan really had a headache in the face of Gu Yuan.

This kid is good at everything, he just likes to break the casserole and ask the end.

But Lu Yan was just an ordinary sword-wielder, neither a formation master nor a soldier, and he really didn't know how to answer some of these complicated questions.

He even regretted a little, why didn't he ask the previous sword bearer about breaking the casserole when he took over the position of sword bearer?

Are you embarrassed?

"Lord Lu, that's what you want to say?" Gu Yuan asked.

Lu Yan shook his head, suddenly turned his face, and looked at Pang Ying who was following behind him.

Pang Ying was a little surprised, but she quickly came back to her senses and said with a smile: "You guys talk first, I'll go out and have a look." ”

Then, even the two guards at the entrance of the small building walked away.

Looking at Lu Yan's solemn expression at the moment, Gu Yuan's heart tightened, knowing that Lu Yan might be going to say something terrible next.

"Gu Yuan, do you know why we are called Sword Bearers?"

Gu Yuan shook his head.

He could think of a lot of theories, but he didn't think it was time to delay.

Since Lu Yan asked, let him say it himself, and the other party didn't really want to discuss academics with him.

Lu Yan's next focus is still on the platform in front of him.

"Every sword-wielder has a special ability, but this ability can only be used once." Lu Yan said, "In the entire Star City, there is still a large array, and the location of this small building is the eye of the large array. ”

Gu Yuan was a little surprised.

"Star City...... There's even a magic circle hidden? ”

"Yes, this magic circle is also related to the sand table in front of you, the key to open the magic circle is the city seal, when there is a great catastrophe in Star City, as long as you open the magic circle, with this place as the center, most of the Star City will be shrouded by a barrier, which can last for about three days." Lu Yan said, "Remember, this magic circle can only be used once, and when the magic circle is urged, the city seal will be completely shattered." ”

Gu Yuan nodded in astonishment.

Lu Yan's information made Gu Yuan's brain a little confused.

In the world, there is still such a magic circle??

Sounds amazing!

"Gu Yuan, you remember, this magic circle is the sword in the hand of the sword holder, and you must hold it in your hand at all times, but this sword must not be swung out unless it is absolutely necessary."

Listening to Lu Yan's words, Gu Yuan asked, "Then what is the last resort?" ”

"I don't know, no one has used it until now." Lu Yan said, "As for the timing of use, it's up to you to grasp it." ”

Lu Yan had already made the key points clear, and Gu Yuan had also taken it to heart.

"This thing has been able to exist until now, and no one has used it?" Gu Yuan whispered.

"What do you think, the materials for making the city seal were only discovered ten years ago, and you think they have already been there?" Lu Yan couldn't laugh or cry.

Gu Yuan suddenly realized, scratched his head, and said, "This kind of formation should be very troublesome to arrange, right?" After all, it's the formation of the whole city! ”

"That's nature, haven't you noticed that in recent years, many cities have been building roads all the time? But the question is, why does it take so long to build a road? ”

Gu Yuan was stunned and said, "Could it be that the formation master is arranging the formation?" ”

"Clever."

Gu Yuan was so excited that he was about to cry.

The problem that has plagued him for so many years has finally been explained.

In the future, if he sees which road has not been repaired well for so many years, Gu Yuan will never complain again, he knows that there is a formation division who is escorting the city.

He really, I cried to death!!

"That's right, that is to say, this big array can only protect Star City, so ...... What about other counties, villages and towns? Gu Yuan asked.

"Then it can't be helped." Lu Yan said, "First of all, the materials are not enough, and secondly, not to mention those villages, towns and counties, in the Great Xia Kingdom, not all the sword wielders in all cities have city seals, and they don't even have the ability to teleport the sand table." ”

Gu Yuan nodded and stretched out his hand towards Lu Yan.

"Show me something."

Lu Yan's face darkened: "You're in a hurry!" I'm not gone yet! ”

In the following time, Lu Yan and Gu Yuan talked about the essentials of teleportation.

When Gu Yuan almost mastered it, it happened that the phone rang too.

The call was made by Guan Pingyue, saying that someone had already come to the Guan family, and he wanted to ask Gu Yuan to have a meal in the evening and have a good talk, of course Gu Yuan agreed, in the end, this time he asked the Guan family to do something!

After hanging up the phone, Gu Yuan furrowed his brows and looked solemn.

He was thinking that even if the Guan family was willing to hand over the medicinal materials to him, he must have conditions.

So what will they ask for?
