The Thunder Fortress is the most powerful force in the southwest of the entire Yasan Peninsula.

The area actually controlled by the Thunder Fortress is extremely vast.

The extent of the vastness is even close to the entire realm of the Grey Wilderness.

And in this vast territory, there are base cities, fortresses, fortresses, and the core of the Thunder Fortress system, the only Thunder Fortress City.

In addition, there are a large number of small and medium-sized base towns, micro and micro bases.

Almost every fortress city system consists of a fortress city as the capital, multiple fortresses, fortresses, and a large number of base cities, base towns, and low-level bases.

The miniature and micro-miniature bases on the ground floor are all over the periphery of the Thunder Fortress system.

Form a first-tier sentry protection ring to guard the base towns in the circle.

A large number of small and medium-sized base towns form a second layer of protection to protect the base cities in the circle.

The base city is the fortress's barrier.

The fortress exists as a barrier to the fortress.

As for the fortress, it is responsible for defending the capital of the entire fortress system, the Thunder Fortress City.

A Stronghold is a member unit of the Stronghold City system located on top of the Stronghold, and is also the capital and leader of the entire Stronghold City system.

Approaching the wilderness of a base on the southwestern barrier of the Thunder Fortress city, a group of people riding dangerous creatures and exuding an extremely strong aura were walking on the wilderness.

When the group approached the base, the personnel stationed in the base saw the scene thousands of kilometers away from the periscope, and they only felt cold.

"These people don't have the identity sensing signal of the fortress system, they are strange masters."

"Gotta report to the sir."

"Let's hope these people aren't enemies." The garrison immediately dialed the landline telephone hanging on the wall in the observation room.

There are many types of bases in the base of the Thunder Fortress system, which are divided into various types of bases, such as advance bases, sentry bases, defense bases, observation bases, secret bases, and evacuation bases.

The G73 Shelter, which has been regarded as a self-reserved place by Su Huan, was actually originally built according to the specifications of the miniature refuge base of the Thunder Fortress City System.

Micro bases usually have hundreds of people, while micro bases are usually staffed by thousands of people.

This base is a sentry base.

Unlike the forward base, which is used to expand its territory and drive it firmly into the unoccupied territory like a nail, the role of the sentry base is to be a sentry and a vigilance.

This outpost base is only the smallest small base, with no more than 100 people stationed there.

The personnel stationed in the observation room quickly contacted the chief officer of the outpost base.

When the highest-ranking officer at the outpost base heard his subordinate's description, he first frowned, but then his brow relaxed.

Although the number of people who came was more than ten heads, this force flew far beyond the power of their small tiny sentinel base, and it was not even a mantis arm as a car.

Normally, if the other side is a hostile force, the only thing this outpost base can do is to convey the hostile situation and let the later bases prepare early.

But this time, the commander in charge of the base acted as if there was no such thing, and only told the sergeant who discovered the situation to continue to maintain normal observation and vigilance, and not to act aggressively.

A kilometer away is just a fraction of a moment away for a horror species.

This group of people is naturally Su Huan and his entourage, who have been on the road for a day and a night.

Half an hour ago, everyone was still riding a flying pet.

However, as they were about to approach the true border of the Thunder Fortress City, under the orders of Master Lu Muping, everyone changed to land mounts to control their pets.

When Lu Muping and some people approached the military structure, which was made of black special materials, the group stopped their mounts one after another.

The momentum brought by more than a dozen terrifying species was almost to make the young sergeant in the observation room tremble, he really couldn't help but take out the matching gun from his waist, opened the safety bolt, and told him that this matching gun could bring him a little comfort, in addition, the young sergeant also summoned his own pet.

In the entire Ringing Thunder Fortress city system, the master has been completely popularized, as a soldier of the border guards, naturally everyone is a master, but they are only low-level masters with low strength.

In the entire sentry base with hundreds of people, only one military commander is a professional-level pilot.

The rest of the people are all apprentices.

"We are a master from Gilded City, and we have been invited to participate in the regional competition held in Yuege City, in order to avoid our next trip being blocked, please provide us with identity sensors." With a wave of Lu Muping's hand, the three quasi-master-level pilots from the Gilded Consulate immediately instigated their mounts to approach the sentry base, and used their spiritual power to expand their voices and speak loudly.

The identity sensor is a device invented by the Thunder Fortress City to allow the border guards to distinguish between friend and foe, and the people of Gilded City obviously do not have it.

This kind of identity sensor is prepared for people who have gone out of the Thunder Fortress City, so that they can return unhindered without being questioned by the sergeant of the border base or even arrested by the border army.

If there were no identity sensors, Su Huan and his party were afraid that if they went some way deeper, they would face a large number of legions of the Thunder Fortress City System.

Don't look at the strength of everyone, they are not weak, but they are pitifully weak compared to the entire Thunder Fortress City system, and even in the face of Moon Song City, they are extremely weak.

However, when invited to participate in the Yuege City event, the other party stated in the invitation that he only needed to show the invitation letter to the base commander at any border base, and he would be given an identity sensor.

Sure enough, there was a quick response in the base: "We are the border troops of the Yuege City Local Corps under the Southwest Frontier Group Army of the Thunder Fortress City, and Yuege City has already conveyed an order, stating that there have been outside professional-level pilots entering the country recently. ”

"Please send me an invitation from Yuege City."

Lu Muping shook his hand slightly, and a black card floated in the air, slowly flying towards the sentry base.

Immediately in the base, a sergeant and a pet-driven pet caught the black card in the air and handed it to the base commander who had moved to the observation room.

The base commander inserts the black card into a reader, and the reader's display begins to display a unique invitation code with the content of the invitation.

"That's right, the identity is right."

"There are sixteen people on the other side, and these sixteen identity sensors are sent to the other party." The base commander instructed the sergeant who had handed him the black card.

"Yes." The sergeant carried a box and headed out of the base.

Soon, the sensor was handed over to Su Huan and his party.

Su Huan and others have one for everyone.

At this time, the voice of the base commander sounded again from the loudspeaker device in the base.

"Ladies and gentlemen, this is just a temporary identity sensor, you must feel Yuege City within three days and register as a contestant in order to get long-term status, remember."

Su Huan and his entourage left the sentry base and headed in the direction of Yuege City again.
