Xuanyuan Dynasty, Xuanyuan Dragon City.

The Xuanyuan Star Dou Great Array had been fully opened, and the brilliant colorful brilliance had circulated for thousands of miles, blocking the road to the south of the immortal clan.

Tens of billions of undead strange birds covered the sky and the sun, and the gray light continuously bombarded the Xuanyuan Star Dou Great Array, causing this tenth-level formation group to shake from time to time.

Most of the river bigwigs of the entire Xuanyuan Dynasty were concentrated in Xuanyuan Dragon City, fighting to the death against countless undead monsters.

However, even with the assistance of the Xuanyuan Star Dou Great Array, the Terran side was still losing and retreating, and the undead were killing as much as they could through the formation.

The Tang Dynasty Immortal Dynasty has already sent the strong people of all races to rescue, if it were not for this, Xuanyuan Dragon City is afraid that it will be difficult to hold on to even a day, unfortunately the time is still too short, the Tang Dynasty Immortal Dynasty is simply unable to mobilize a large number of troops of all races to help, and in the face of the tens of billions of elite legions of the undead clan, it is inevitable that they will be defeated and retreated.

The most important thing is that the immortal clan has an eleventh-level mythical existence of the immortal phantom phoenix, but there is no corresponding strong person to protect it in the Tang Dynasty, so it is suppressed very miserably.

This mythical-level immortal phantom phoenix would launch several big moves from time to time to kill some of the more active river bosses, and at the same time, he was also observing the flaws in the Xuanyuan Star Dou Great Array, preparing to find an opportunity to destroy this huge formation group in one fell swoop.

The four city walls had become meat grinders at this moment, and the cultivators of the human race fell in large numbers.

"These undead are so terrifying, we have obviously killed them, but in the blink of an eye, they actually came back to life in the distance, what the hell is going on. ”

"As the name suggests, their soul imprint is held by the undead phantom phoenix, as long as something happens, the undead phantom can resurrect them through the soul mark, so this race is called the undead. Only when we destroy the immortal phoenix will the undead die completely, otherwise they will be resurrected in an endless stream. ”

"That immortal phantom phoenix is an eleventh-level mythical existence, no one of us here is its opponent, only His Majesty the Tang Emperor can kill it, but His Majesty the Tang Emperor is not here, where did His Majesty the Tang Emperor go. ”

"It is said that His Majesty the Tang Emperor has entered the Blood Plains and wants to clear the hidden dangers of the Blood Plains for our human race, so he is not on the surface for the time being, and we can't contact him. I didn't expect the undead to come over at this time, what a coincidence. ”

......

As the name suggests, the Undead will not truly die if their soul sigils are not destroyed, and as long as the undead are willing to expend their Origin power, they can be resurrected through their soul sigils.

So the war lasted for a day and a night, but the undead didn't seem to have many dead, but the Terran side had already suffered heavy casualties.

If this rate continues, I am afraid that in less than ten days, Xuanyuan Dragon City will be breached, and this is still under the condition that the Tang Dynasty Immortal Dynasty fully supports Xuanyuan Dragon City.

Without the support of the Tang Dynasty Immortal Dynasty, just relying on the power of Xuanyuan Dragon City, I am afraid that in less than three days, Xuanyuan Dragon City would be destroyed by the undead clan.

Time passed bit by bit, and more and more strong people came to help, but unfortunately, in the face of the undead monsters who couldn't be killed at all, Xuanyuan Dragon City still tended to collapse little by little.

After a few days and nights, the huge Xuanyuan Dragon City had almost become a dead city, and all cultivators with some strength had already climbed the city wall, or died there, or were still fighting bloody battles.

"Netherfire!"

At a certain moment, the immortal phantom phoenix sitting in the rear suddenly rose into the sky, appeared directly in front of Xuanyuan Dragon City, spat out a gray-red line of fire the size of a bucket from its mouth, and shot towards a certain well in the east of Xuanyuan Dragon City.

That is where the core formation of the Xuanyuan Star Dou Great Array is located, once it is broken, the Xuanyuan Star Dou Great Array may not collapse immediately, but its power will plummet by at least more than half.

The powerful Xuanyuan Star Dou Great Array couldn't withstand the crazy attack of the undead clan, and it looked like it would be broken in a few days, let alone the Xuanyuan Star Dou Great Array that had been destroyed by nearly half of it.

If the blow of the Immortal Phantom Phoenix really destroys the core formation of the Xuanyuan Star Dou Great Array, the Xuanyuan Star Dou Great Array, whose power has been greatly reduced, will probably be broken in less than a day, and what awaits everyone at that time is a certain death.

"White jade is the wall, and the god is the capital!"

At the moment of life and death, the huge and brilliant Bai Yujing suddenly shrank ten million times, turning into a barrier several meters in circumference, blocking above the Netherfire Line.

Cai Immortal sat cross-legged under the barrier that Bai Yujing had transformed, and the spiritual power, spiritual power, and qi and blood power in his body poured into Bai Yujing endlessly, making Bai Yujing bloom with the most brilliant brilliance.

"When ......"

The Netherfire Line and Bai Yujing clashed, emitting a crisp and pleasant sound, which made people feel light.

But at this time, the strange shock wave was like a waterfall, and it did not spread in all directions, but fell downwards on the Cai Immortal.

"Poof......

Cai Shenxian couldn't help but spit out a mouthful of blood, and his body was faintly pale under the impact of the netherworld fire line, and at the same time, imperceptible cracks appeared.

Fortunately, although the injury was not light, Cai Shenxian blocked the inevitable blow of the Immortal Phoenix, and guarded the core formation of the Xuanyuan Star Dou Great Array, so that the last barrier between this Xuanyuan Dragon City and the Xuanyuan Dynasty would not collapse.

"Hold on a little longer, Junming will soon come out of the Blood Plain, and at that time it will be the end of the undead clan!"

Cai Immortal endured the pain and said in a long voice to the Terran cultivators who were struggling to support him.

Many of the cultivators guarding the city responded in unison, and once again threw themselves into the fight, letting blood and skulls be scattered.

"Sneer......"

At this moment, another netherworld fire suddenly came and landed on Bai Yujing.

"When ......"

In the crisp and pleasant voice, Cai Shenxian spat blood again, and the cracks faintly emerging on his body became even bigger.

Seeing that Bai Yujing still hadn't broken through, a cold light flashed in the immortal Phantom Phoenix's evil eyes, and a trace of coldness crossed it, and the Nether Fire Line in its mouth kept spitting out, it wanted to see how many Nether Fire Lines a mere River Realm cultivator could resist it.

"Poof......

"Poof......

"Poof......

......

The netherworld fire line kept coming, and the blood in the mouth of the fairy was spit out as if he didn't want money, and there were more and more cracks on his body, reflecting the white jade-like skin, like a porcelain doll about to shatter to the ground.

Some of the surrounding river bigwigs and Huixi giants wanted to save her, but they were entangled by the strong men of the undead clan, and they could only watch the immortals go to death.
