The Gu Yue family members stayed behind and left Taiyi Realm last. In addition to strengthening communication with Taiyi Realm, they also wanted to actually test the fairy gate they gave to Taiyi Realm.

Immortal gates are usually refined one by one.

Placing these pairs of immortal gates in two places far apart in the void can allow the two places to be directly connected through special space channels, allowing people and materials to be directly transported.

Immortal Sect is not easy to refine and the quantity is small. It is a treasure of great strategic significance.

Those big forces with the ability to refine the Immortal Sect generally will not easily spread the Immortal Sect.

Back when he was in the Hengling Star Region, Meng Zhang wanted to obtain the Immortal Sect.

However, because the Taiyi Realm had just attached itself to the Wuliang Tianzong at that time and had not yet been officially recognized by the Lingkong Immortal Realm, and there was someone in the middle who was causing trouble, Meng Zhang was never able to get what he wanted.

Now, the Immortal Sect presented by Gu Yue Lingbo personally not only satisfies the curiosity of the senior officials of Taiyi Realm, but also has important practical value.

If there are enough immortal gates, and arranged according to special methods, they can form a network that connects multiple places in the void.

Top cultivation forces like the Lingkong Immortal World mainly rely on the Immortal Sect to connect their many subordinate worlds scattered throughout the void and manage their vast territories.

Of course, since Immortal Sect is very precious, it is very difficult to build a network.

Those territories that are not valuable enough and are too remote may not be eligible to join the network built by Xianmen.

The Junchen Realm, where Meng Zhang was born, had never joined the fairy sect network of the Lingkong Immortal Realm.

This was the result of the fight between the old friends and enemies of Junchen Immortal Lord, and it was also because Junchen Realm was too remote, and as a new world, the output was not rich enough.

Meng Zhang later heard that after the Junchen Realm was destroyed and the Lingkong Immortal Realm officially regained control of the Dengtian Star District, they began to try to incorporate the Dengtian Star District into the Immortal Sect Network.

Generally speaking, fairy gates are opened in the void outside the big world.

Due to the special situation of Taiyi Realm, it spends most of its time wandering in the void, and due to safety considerations, it is impossible to keep the Immortal Gate open above it.

Now, taking advantage of Gu Yue Lingbo's visit to the Taiyi Realm, he just happened to open this immortal gate, not only to test its functions, but also to officially start communication and exchanges with the Gu Yue family's territory.

Under the gaze of everyone, Meng Zhang gently threw the small fairy gate in his hand into the void.

Xianmen flew to a place not too far away from Taiyi Realm and stood quietly in the void.

As Meng Zhang cast the spell, the Immortal Gate suddenly grew in size and turned into a giant arch, with a special space passage in the gate.

Judging from the size of this arch, smaller void battleships can pass through it.

After that, as long as there is an immortal responsible for maintaining it and maintaining a sufficient supply of spiritual energy at all times, this fairy gate can always remain open.

After a joint inspection by Meng Zhang and Gu Yue Lingbo, it was found that the Immortal Sect was in normal condition and could be safely passed through.

On the other side of the Immortal Gate is the core territory of the Gu Yue family, which also has no problems.

In the following time, Taiyi Realm and Gu Yue Family began a large-scale movement of personnel and materials.

Many high-level monks from the Taiyi Realm are the spies sent by the Taiyi Realm, lurking deeply in the Lingkong Immortal Realm.

For so many years, Taiyi Realm has been wandering in the void, and the communication with these monks is not smooth.

Moreover, so much time has passed, and many of these monks may have died.

As for these monks revealing their identities, it's not a big deal.

The Lingkong Fairyland and the many big worlds under its command receive countless foreign visitors almost every day.

Many of these visitors are spies sent by major forces in the void.

As long as these spies don't make too much noise, it will be difficult for the Lingkong Immortal World officials to maintain a high-pressure state.

The vast majority of spies have no access to the real secrets of the Lingkong Immortal World and only collect some daily information.

To seal off the Lingkong Immortal Realm and cut off all kinds of commercial activities just for the sake of some spies is not worth the gain.

In the void, a large part of the overt and covert struggles between the various cultivating forces consists of sending spies to spy on each other.

Not to mention those hostile forces, even many allies will also spy on each other.

Many times, even if many cultivating forces discover outside spies, they will basically turn a blind eye and not make a big move.

Depending on changes in the relationship between the two parties, cleanup operations will be initiated regularly when necessary.

Now that Meng Zhang has been promoted to Immortal Lord, he has become even more powerful.

The new spies sent by Taiyi Realm were all subject to special restrictions by him.

Such a restriction can not only protect their identities from being leaked, but also help them contact each other and even the Taiyi world.

The Taiyi world is mainly composed of cultivators, and there are also many gods and their followers.

Some powerful gods are able to maintain contact with their followers even if they are far away from them.

Moreover, the loyalty of the vast majority of believers to the gods can also be guaranteed.

The Moon God is not only a powerful god, but also has many aspects of secrecy and infiltration in his priesthood.

Among her followers, many outstanding spies were born.

Under An Moran's organization and coordination, many spies sneaked into the Gu Yue family's territory through the Immortal Gate, and then used this as a starting point to slowly penetrate into other parts of the Lingkong Immortal World.

Even if the time is right in the future, these spies will use the spiritual world as a springboard to infiltrate other forces in the void.

This is a long-term project with huge investment. It is no exaggeration to say that this is a plan that takes thousands of years to plan.

This is of great significance to the Taiyi world.

At the very beginning of the plan, there was no need for these spies to provide any confidential information. They were just the eyes and ears of Taiyi Realm, allowing Taiyi Realm to keep in touch with the outside world and learn about some trends in the outside world.

As an independent world, Taiyi World has been wandering in the void.

The closed environment not only protected Taiyi Realm, but also brought many inconveniences.

In addition to practicing in the void, monks in the Taiyi world also need to contact monks from other forces in order to be perfected in all aspects.

The Gu Yue family is like a window that allows monks in the Taiyi world to maintain contact with the outside world.
