Before the wind blade could hit, it was shattered by the electric field condensed around Lei Huang. The sixth-level mutant bird screamed in surprise and thought, "Yeah, escape, but Lei Huang's sharp beak wrapped in thunder energy, hit the back of the sixth-level mutant bird first.

With a sting, the sixth-level mutant bird was immediately torn apart, and blood and feathers splattered in the air. The mutant birds chasing behind were in chaos in an instant.

"Hahaha. Boss is here to save us!" Zhou Jian immediately cheered, and Li Luo also lit a cigarette for himself again.

Yu Tian's chuckled in his ears: "Eve, take them forward and leave it to me!"

"clear."

Eve rushed towards the direction of southern Liaoning with all his might, and Lei Huang was already entangled with the sixth-level mutant bird and completely took the initiative.

The sixth-level mutant bird kept getting wounds on its body, and the continuous thunder exploded even more.

Yu Tian gently patted Lei Huang's back: "I'll give you one minute, and you have to go to someone else in the safe area."

"Chi——"

The loud hissing is Lei Huang's response.

The Victory Watcher turned around and saw only the thunder in the sky behind him. The black sky seemed to be suddenly torn apart by a force, and a large blue thunderstorm poured from the sky like a waterfall, submerging the sixth-level mutant bird...

...

At this moment, major safety zones also launched firepower strangulation at the mutant legion in front of them.

Countless missiles flew into the air from major safety zones, and powerful artillery fire would strangle all the mutants directly in front of the major safety zones. Then, all the major safety zones suddenly took the initiative.

The mechanized troops, which turned into a torrent of steel, rushed to the forefront and dispatched a number of mutant legions on the plain to fight against many mutant legions. The air forces formed a formation and rushed towards the direction of the occupied area, fighting against many mutant birds in the air.

The mutant legion has never been so provoked, and has turned its attention to the front. This has gained the retreat space for the infiltration team to evacuate.

But even with the cooperation of major safety zones and the assistance of Yu Tianleihuang and many air forces, 30% of the elite teams failed to evacuate during the retreat and were buried in this battlefield forever.

But in general, the major safety zones still won.

Under the leadership of Yu Tian, ​​a miraculous infiltration battle was completed!

The people in power in major safety zones met Yu Tian again, and everyone looked happy.

"It's so awesome. I really didn't expect it to succeed, and the price was so small."

"To be honest, I thought my people could not come back until just now."

"Thanks to Yu Tian who used the Sky Demon to pinch the Devourer, otherwise my safe zone might be the next safe zone to be killed by the Devourer."

"Yu Tian, ​​I really accept you. He is so powerful when fighting with you." A person in charge of a safe area laughed and wanted to fly out of the screen to give Yu Tian a big bear hug.

Yu Tian just smiled slightly: "This is just the beginning. We will disrupt the fallen areas behind the mutant. The war is rapidly expanding, but it will take some time to relieve the defense pressure of our major safety areas."

"Don't relax during this period. If you have any difficulties, we can solve them together. I believe that as long as we work together to establish an offensive and defensive alliance, there will be no difficulties that can defeat us."

The people in power in major safety zones nodded one after another. At this moment, their eyes had changed when they looked at Yu Tian. At this moment, Yu Tian and the Demon Hunter are no longer just the strongest among the major safety zones, but also the leaders of the defense operations of the entire Yanhuang Fortress outer security zone.

He is the head of this alliance at this moment, and no one can shake it!

But what made everyone even more excited was that Yu Tian talked about the offensive and defensive alliance!

Everyone looked at Yu Tian with excitement. Yu Tian put away his smile and said seriously: "Since everyone has a foundation for cooperation, I think there is something I can raise at this time."

He snapped his fingers and the Ghost Queen immediately sent her detailed strategic plan to everyone.

When I opened the first page, I was immediately shocked by the amazing content and wild ideas!

Everyone looked at Yu Tian, ​​his eyes full of disbelief!

This plan is simply a fantasy that only a madman can imagine.

This strategic plan is called: Star Cluster Defense Plan!

It is to connect each security zone outside the Yanhuang Fortress one by one to form a comprehensive star-chain wind and rain system, supporting each other and supporting each other. When one side is in trouble, it is not to fight alone like in the past.

What's even more amazing is Yu Tian's idea.

Infiltration and counterattack combat is actually just the first step in the entire idea!

The second step is to send air formations to open up the air connections between major safety zones and establish air support channels while the mutant body is in chaos.

The third step is to let the ground troops leave the safety zone and continue to advance. With the cooperation of missile troops and air forces, the relative safety zone of about 10 kilometers is cleared in front of the safety zone.

Establish buffer defense barriers. Restore production of grain and various production units, collecting legacy spoils.

But that's not enough!

Yu Tian’s fourth step is to send people to rebuild the breached safe zone.

There is a fifth step!

Each safe area has a soil element evolutionist. Yu Tian actually plans to use the capabilities of the soil element evolutionist to build underground fortifications in the underground of major safety areas, and connect all safety areas in the form of tunnels to establish an underground steel Great Wall buried deep underground in the safety area!

Establish a star-chain defense system!

In this way, all safety areas will be fully connected.

With missile forces as the first layer of defense, air formations as the second layer of defense, ground forces as the third layer of defense, underground connections as logistical support, dozens of safety areas outside the Yanhuang Fortress are built into a trinity-integrated super joint defense system!

It will be equivalent to building a steel wall outside the Yanhuang Fortress, and each safety zone will be nailed to the spot like a nail, becoming a fortress for the guardian alliance!

This is the star cluster!

Even if the civil strife of the mutant has subsided, if you want to attack the major safety zones, the major safety zones will have enough strength to deal with their challenges!

Everyone was shocked by Yu Tian's strategy. Then they all took a breath.

This is simply a madman who can imagine a strategic plan.

Each step of the imagination is fantasy, and everyone's first feeling is that it is impossible to complete. The first few steps are a little more reliable, but rebuilding a destructive safe zone and opening up an underground tunnel is simply fantasy.

What is this huge project different from rebuilding a Great Wall!

Similar ideas have been proposed in the past, but they were quickly rejected.

After all, the two safety zones are nearly 100 kilometers apart, and various problems may be encountered during this period. It is impossible to achieve a huge time-consuming and laborious project like digging tunnels.

Moreover, the major safety zones are not completely united and have their own small calculations. People who work harder and who work harder will not be willing to suffer losses. This feat is impossible to achieve with this concept.
