"Teleportation array? Head of the family, are you talking about the teleportation array that can teleport each other over long distances?" Hall Master Tao asked with a shocked look on his face.

"That's right! That's the one!" Cheng Yu nodded.

"But hasn't that been lost a long time ago? How could the head of the family..." Hall Master Tao said with a look of surprise and confusion.

He just thought that the teleportation array mentioned by the family leader was not what he thought, it was just the same name.

But now that I got the affirmative answer from the head of the family, I feel like my brain is really a little bit frozen.

It is said that teleportation arrays actually existed in the human world very long ago, but there is no evidence for this.

In addition, no one has ever discovered relevant ruins, and no one in the world has reported that anyone has obtained any documentation about the teleportation array.

This has led many people to question the fact that teleportation arrays have really appeared in the human world.

But at this moment, the head of the family found them and actually told him to build a teleportation array. This really shocked all of them.

"It was lost because no one found it. If it couldn't be found, wouldn't it be lost?" Cheng Yu said with a smile.

"The master of the house means that you have found it?"

"You can say that, so isn't this for you to learn? In the future, you will arrange more teleportation formations for me." Cheng Yu nodded.

"Thank you, Patriarch, for your cultivation. We will definitely live up to Patriarch's expectations and complete the layout of the formation for Patriarch." Everyone was immediately excited.

This is the legendary teleportation array. They never dared to imagine that they would have such an opportunity.

Because they never thought that the teleportation array was real.

But they believed that the head of the family would not come here specifically to make fun of them. Since he said so, then this teleportation array is real.

Moreover, the head of the family wants them to learn, and in the future they can even set up teleportation arrays on their own, which is really amazing.

"However, teleportation arrays have high requirements on resources and consume a lot of resources, so we will not deploy too many teleportation arrays for the time being because we cannot afford them.

If there is still demand in the future, we will gradually add teleportation arrays so that the entire world is covered with teleportation arrays, so that it will be more convenient for Cheng family disciples to go anywhere in the future.

But based on the current situation, the teleportation array is not for personal use, but is mainly used for important family operations!" Cheng Yu explained to everyone.

Looking at these more than a hundred people, his heart was full of expectations.

Compared to the scarcity of alchemists in the Alchemy Hall, the number of high-level formation disciples in the Formation Hall is much larger.

After all, in order to build various cities, he trained a large number of formation disciples, so he spent much more resources in the formation hall.

And because the Cheng family itself has too many elixirs, and excellent alchemists are very rare, the number of alchemists is far less than that of the Formation Hall.

However, now the Cheng family is also vigorously cultivating alchemists, so I believe that in the coming years, the number of alchemists in the Cheng family will quickly catch up.

The arrangement of the teleportation array is a very complicated combination of formations, so if he were to do it alone, it would take at least half a year to set up a teleportation array.

But with the help of these disciples, I believe it can be completed within a month.

"We understand!" After hearing Cheng Yu's explanation about the teleportation array, everyone can understand.

If the teleportation array could be used by individuals at will, perhaps the teleportation array would not disappear.

It is precisely because building a teleportation array is very expensive and requires a huge amount of resources that no one can afford it.

It can only be afforded by relying on a powerful family like the Cheng family.

So after those big families perished, naturally no one had the ability to build a teleportation array.

Therefore, if there were no major events, it is estimated that the Cheng family would not let any disciples use it, which is completely understandable.

But for people like them, it doesn't really matter who can afford it or not.

As an array master, they just want to learn the layout of this lost teleportation array. Being able to learn such an ancient array is what they should be proud of.

"Now that everyone understands it, let's get started! The teleportation array itself is actually not that difficult, but it is an extremely complex combination array, so it takes a little long.

However, you are actually very experienced in complex combination formations.

When the Cheng family's cities were built, you all laid out the city's protective formations, so the teleportation formation this time is not a big problem for you." Cheng Yu explained to everyone.

Everyone nodded, they indeed have rich experience in setting up combination formations.

Because the city defense formations deployed in many cities are actually a single giant formation.

However, in order to ensure the safety of the city to the greatest extent, Cheng Yu naturally selected the most powerful and suitable formation from the Immortal and Demon Tower, so it was a complex combination of formations.

These city defense formations can be used both offensively and defensively, and they are absolutely very powerful whether offensively or defensively.

At least from this world, apart from the huge energy consumption, there are basically no shortcomings.

"So in my opinion, the reason why the teleportation array has disappeared in this world is not because of how complicated the teleportation array is, but because it is too expensive. If there is not enough resources accumulated, even if the construction of the teleportation array is known,

, and there is no ability to build it at all." Cheng Yu said.

"Master, what kind of resources are needed to build this teleportation array?" Hall Master Tao asked curiously.

Although he is the leader of the Formation Hall, he is also a high-level Formation Master, otherwise it would be impossible to manage the entire Formation Hall.

"Fairy Crystal!" Cheng Yu said and took out a fairy crystal.

"Fairy Crystal? But isn't this something that only exists in the fairy world?" Everyone was shocked again when they felt the rich fairy energy emanating from the fairy crystal in Cheng Yu's hand.

Everyone is in the period of transcending tribulation and understands the importance of the spirit spirit to them even more.

In today's world, because there is no fairy spirit, it is extremely difficult to transform the fairy source.

Therefore, everyone will drool after looking at the Fairy Spirit Crystal in the owner's hands.

They didn't know how the family leader could have the Fairy Spirit Crystal in his hand, which is only found in the fairy world.

"Since there has been a teleportation array in this world, it means that there were fairy crystals in this world, but they were very rare.
