After driving away the zombies in the east, Lin Ya took the escort team and the mutant birds to fight on the other three sides non-stop.

The southern battlefield is also led by a sixth-level mid-level corpse king. Due to the mysterious connection between the zombies, the southern corpse king knew that the two corpse kings in the east had led the team to escape, so under a slight collision with the Sky Wolf Army, the southern corpse king knew that he had no chance of winning, and immediately retreated.

Lin Ya had a little trouble in the west. The Corpse King on the west side is a sixth-level upper rank. The wisdom of the sixth-level upper-rank corpse king is no different from that of ordinary people. And this corpse king is the wind corpse king.

The Wind Corpse King can float in the air for a short time. It relied on its unpredictable speed and level suppression, and cooperated with the zombie bird flock to launch a counterattack against the Sky Wolf's air forces.

Under the brazen counterattack of the Wind Corpse King, it actually killed two mutant eagle eagles of the fifth level.

Fortunately, there were no riders on the backs of the two eagles. Otherwise, there will be casualties among the Celestial Wolf Army.

But this proud Wind Corpse King didn't get much benefit either. The Sky Wolf Guard, who reacted, immediately took out the Crystal Gun and set fire to it at any cost.

The Wind Corpse King had a chance to escape the blow, but it was too close to the Celestial Wolf Army. Under the effect of Wenwen's telekinesis binding and Lin Ya's time deceleration, its air mobility ability was greatly reduced. The corpse king was hit by the crystal spear repeatedly.

A hundred crystal energy guns concentrated fire and attacked three rounds, and they exploded this corpse king.

Lin Ya was overjoyed, and popped out the wicker to collect all the remnants of the Wind Corpse King. One sixth-level upper-order crystal nucleus can be used as nine sixth-level primary-order crystal nuclei. And the three rounds of strikes only cost six grains of sixth-level primary energy.

Purely from the crystal nucleus, Lin Ya has earned.

Not only did he earn the crystal nucleus, but the key was that the body of this sixth-level upper-level corpse king was equal to one hundred and eighty catties of sixth-level upper-level ant honey!

Lin Ya didn't know that in her brother's place, this body was equivalent to a sixth-level upper-level red and blue potion and an even more valuable sixth-level upper-level spiritual power potion.

The remaining corpse king on the western battlefield was a sixth-level mid-level fire system. The Fire Corpse King was frightened when he saw the sixth-level Wind Corpse King breaking through the sky.

The Fire Corpse King didn't have time to think about it, and with a long roar, he summoned his subordinates and began to escape.

Since the situation of the battlefield in the south had already been reported to the Fire Corpse King, the Fire Corpse King fled with all his heart, and there was no more moths.

Of the 300,000 zombies belonging to the dead Wind Corpse King, about 200,000 zombies were controlled by the Fire Corpse King, who immediately changed their leadership and fled to a distant place with the Fire Corpse King. However, the leadership of the sixth-level mid-level corpse king was limited after all, and in a short period of time, it was too late to control all the wind-based corpse kings. The 100,000 zombies closest to Feifeng City belonging to the Wind Corpse King were not included in the leadership of the Fire Corpse King.

The 100,000 zombies were suddenly at a loss, staring blankly at their companions in the distance, and then turned their heads and roared angrily at the Sky Wolf Army's sky troops.

Lin Ya found the fighter plane in the air, and she knew that the other corpse king had left the 100,000 zombies behind and gave them to humans.

A mutant eagle carried Zhai Fengcheng back to the city quickly, informing the people in the city to quickly go out of the city to harvest the 'gift' left by the Fire Corpse King to the human side.

Previously, as the zombies in the East and South Cities retreated, the focus of the defending forces had shifted to the West City and the North City. As soon as Zhai Fengcheng's order was issued, a large number of men and horses rushed out of the south gate and headed for the battlefield.

The Ice and Snow Division inherited the tactics handed down from the Heavenly Wolf Headquarters, with more than 10,000 Ice and Snow Divisions as the main force and more than 10,000 civilian forces as the auxiliary, and slaughtered forward with great momentum.

Under normal circumstances, with the power of Feifeng City, it would not be able to defend against the siege of two million zombies on all sides. However, with the defense of the Ice and Snow Division subordinate to the Sky Wolf Army, the situation was different. Because the Ice and Snow Division has enough red and blue potion support, it is not afraid of being injured and can fight continuously for a long time. Coupled with the support of strong city walls, the soldiers of the Ice and Snow Division do not have to worry about being exposed to the enemy on their backs. And their average level is not very different from the average level of zombies. Therefore, Zhai Fengcheng would have said that he had no intention of taking the initiative to attack, but he had the confidence to defend Feifeng City.

The soldiers of the Ice and Snow Division originally thought that they would not have the opportunity to take the initiative in this war, but they did not expect that the opportunity to take the initiative would come so soon. The warriors who left the city formed a tight formation, spewing high battle intentions, and rushed towards the 100,000 corpses that rushed forward in a messy manner.

When the Ice and Snow Division finally connected with the corpse group, the air force led by Lin Ya had already completely annihilated the zombie bird flock left by the Fire Corpse King and fell to the ground. Lin Ya's escort formed a relatively loose formation, and with the cooperation of the air troops, they easily slaughtered the corpses that rushed forward as if they were chopping melons and vegetables.

Without the close organization of the Corpse King, although the number of zombies was as high as 100,000, it could not bring much pressure to Lin Ya's escort. It was only in order to speed up the slaughter that Lin Ya let the Ice and Snow Division join the battle.

Zhai Fengcheng is naturally happy to see it. Although the escort team and mutant bird troops led by Lin Ya stood in the center of the front of the battlefield, the forces of Flying Phoenix City could only fight on both sides, but the forces of Flying Phoenix City could also take down six or seven zombies by virtue of their numbers.

When these 100,000 zombies are completely annihilated, the Ice and Snow Division can obtain at least twenty or thirty thousand fifth-level crystal nuclei. Among them, the fifth-level intermediate and fifth-level upper-level crystal nuclei can also be exchanged for value-added amounts from Lin Ya on the spot. For a long time, the Ice and Snow Division's crystal nucleus for the development of fifth-level masters was sufficient.

100,000 zombies melted away as quickly as rolling soup and pouring snow. When the last zombie fell, good news came from the north.

"Retreat, retreat. Xiaoya, the zombies in the north have retreated. Zhai Fengcheng happily informed Lin Ya.

"The sixth-level corpse king really knows each other. We slaughtered a sixth-level upper-rank corpse king here and quickly eliminated the remaining zombies, which must have terrified the sixth-level upper-rank corpse king in the north. Lin Ya said with a smile.

Lin Ya participated in the battle of Feifeng City and dispersed two million zombies, which took only about two hours.

When Feifeng City was jubilant, the flying fortress that Lin Ya was riding on was about to take off again.

Lin Yazhan did not inform the imperial capital envoy group. When the envoys walked out of the hotel and heard the dream achievements created by Lin Ya, they all felt as if they were in a dream.

After confirming the facts repeatedly, the envoys could only sigh that Lin Chen's brother and sister were both demons.

"Brother Feng Cheng, I can only help you to this extent. The rest is up to you. Lin Ya stood in front of the cabin and said to Zhai Fengcheng.

"Xiaoya, don't worry. These fleeing zombies will not dare to come back in a short time. I'll take the time to exterminate them one by one. Zhai Fengcheng said confidently.

"Brother Feng Cheng, I believe in you." Lin Ya smiled slightly, turned around and boarded the air fortress.

With a roar, the Flying Fortress rose from the ground and flew towards the south.

In the next two days, Lin Ya escorted the imperial capital envoy group, bringing the support of the center of Huaguo to other military bases and more than a dozen large provincial bases, as well as seven or eight large bases established by civilian forces.

Lin Ya saw too many small and medium-sized bases in the air that had been breached or were about to be breached, and saw countless surviving people being torn apart by zombies and mutant beasts on the way to escape.

Her heart was very uncomfortable because of this. Every time she saw a tragic scene, she couldn't wait to immediately kill and eradicate those evil zombies and mutant beasts.

But she could only suppress the impulse in her heart. Because she is responsible for saving more people.

Her next few shots were in Deng Shulin's Yushu City and Tan Su's Suyan City, as well as Li Jun's Longpu City. In these three cities, she didn't take too long to shoot, but she just used air power to trap and kill all the zombie birds among the zombies besieging the city, eliminating the air threat to the defending troops.

Two days later, the Flying Fortress safely returned the Imperial Capital Emissary Regiment that had completed its mission to the Imperial Capital.

After handing over the task to the central military headquarters, Lin Ya didn't have time to rest, she led the escort team to the Baoli City outside the fifth ring road in the east of the imperial capital. Her only best friend, Zhou Fang, is fighting bloodily.

30 million zombies besieged the imperial capital. After two days of hard fighting, the casualties of several major armies in the imperial capital were already not small. Except for the five-ring city wall on the eastern battlefield that has not yet fallen because of Poly City, the troops on the other three sides have abandoned the five-ring city wall and retreated to the fourth-ring city wall.

Fortunately, the area between the 5th and 4th rings is mainly planted. Although it fell, only the mutated crops were lost, and the number of people who died was not too large.

Although Poly City has greatly strengthened the military strength of the Beiyuan Division of the Heavenly Wolf Army with the help of the population advantage of the imperial capital, because there are too many zombies besieging the city, the zombie offensive is endless, and after two days of fighting, Poly City is about to be broken.

When Lin Ya felt it, Zhou Fang was already planning to retreat into the imperial capital. The ordinary people of Poly City have been sent to the imperial capital in advance, and now all the people who need to retreat are warriors.

Poly City is about twenty or thirty kilometers away from the Fifth Ring City Wall. This distance is filled with zombies. Zhou Fang was anxious about this. She feared that her troops would not be able to cross the distance safely.

Lin Ya's arrival helped Zhou Fang a lot. Lin Ya was also weak against the situation in Poly City, and could only support the retreat of the Beiyuan Division.

With the strength of Lin Ya's escort, it is not too difficult to open up only one battlefield. After consuming some level 6 ammunition again, Lin Ya's escort team drove away the corpse king and corpse group that stood in the way, and finally escorted the Beiyuan Division into the imperial capital safely.

As for the breached Kitahara Castle, it could only be rebuilt after the war. As long as the people are safe.
