"The total population of the city is about 600,000. Among them, there are more than 14,000 main soldiers of the Ice and Snow Division. More than half of the main fighters have advanced to level five. There are about 20,000 people with civilian capacity. The rest of the ordinary people were about thirty thousand soldiers. Zhai Fengcheng said.

"Then are you sure about defending the city this time?" Lin Ya asked.

"There is still a certainty of holding on. Speaking of which, if it weren't for the boss who gave the fifth-level crystal nucleus support of the Ice and Snow Division, and let more than half of the soldiers of the division break through the fifth-level, I wouldn't have been so sure, I would have abandoned the city and gone to the military base a few days ago. Speaking of which, the boss released so many fifth-level crystal nuclei last time, which can be described as immeasurable merit. Zhai Fengcheng said in a respectful tone.

"yes, yes. I've heard that quite a few small settlements have been destroyed in the process of zombie gathering. Many medium-sized bases have gained enough fifth-level crystal nuclei to increase their strength and lead the largest number of people to escape into large bases. If it weren't for the boss releasing hundreds of thousands of fifth-level crystal nuclei, I don't know how many more people would have died in this catastrophe. Feng Fei added.

"Brother Feng Cheng, since you have the certainty of holding on, then I can rest assured. You know, I've been on a rescue mission and can't stay here for too long. Otherwise, I'll help you kill the Corpse King, relieve your pressure of defending the city, and then leave. How is it? Lin Ya said with a deep groan.

"Xiaoya, if you can really kill the seven-headed corpse king, then there is naturally no pressure to defend the city this time. Maybe we'll be able to take the initiative to fight back and expand the results. However, there are more than two million zombies outside the city. I can't let you go on an adventure. Zhai Fengcheng was happy at first, and then he was very worried, and did not agree with Lin Ya to capture and kill the corpse king.

Just kidding, if something happens to the boss's eyeballs here, he doesn't need the accusations of the other brothers and sisters of the Sky Wolf Army, he himself will kill himself to thank the world.

"Brother Feng Cheng, I know what you're worried about. But these worries are unwarranted. Since I have put forward this plan, I am sure that it will be completed. Lin Ya said with a firm expression.

"Xiaoya, I know that you are very powerful, and your guards are also very powerful. But the level of zombies is already very high. The average level of the zombies around the Corpse King is half a level higher than ours, and the abilities are also varied. In case ......" Zhai Fengcheng still tried to dissuade Lin Ya.

"Brother Feng Cheng, don't worry. I'm not going to fight the corpses. Lin Ya said.

"Don't fight hard? So how do you kill the corpse king in the center of the corpse group? Zhai Fengcheng was a little puzzled.

"Brother Feng Cheng, let me tell you a secret. You've already seen the power of the Crystal Gun that supports you this time. What do you think of the results? Lin Ya said.

"The effect of the Crystal Gun? Naturally, the effect is good. However, Xiao Ya, after all, the center only gave Feifeng City less than twenty crystal energy guns. Although it is theoretically possible to use the sixth-level crystal nucleus as the launch power, it is unstable after all, and the emission frequency is also low. Besides, where are there so many sixth-level crystal nuclei to waste now? Isn't it Xiaoya, now that the sixth-level crystal nucleus is so rare, you plan to ......" The more Zhai Fengcheng said, the more surprised he became.

Although he had also obtained some sixth-level beginner crystal nuclei from the boss, and the Ice and Snow Division already had several sixth-level capable people, including him, he never thought that the headquarters of the Heavenly Wolf Army had the luxury of using sixth-level crystal nuclei as an energy source for the crystal energy gun.

"Brother Fengcheng, you guessed right. I'll tell you a secret, in fact, my brother has already obtained the complete design drawings including the crystal gun and the crystal cannon from the Jindu Research Institute. You know that our headquarters has established a trade channel with the Genting Mountain Beast Clan, and has obtained enough metal ore for manufacturing requirements. With the efforts of our headquarters scientific research institute, the crystal energy gun produced by Weicheng is more perfect and more powerful than the crystal energy gun produced by the imperial capital scientific research institute. The Imperial Capital's crystal energy gun is only theoretically able to use sixth-level crystal nuclei, while our crystalline gun is theoretically able to withstand seventh-level crystal nuclei. And the transmission frequency has reached five rounds per second. What's more important is ......," Lin Ya said slightly mysteriously.

"What's more important is that the imperial capital may not have enough sixth-level crystal nuclei to test the gun, and as long as we squeeze it, we can still come up with a little sixth-level crystal nucleus. It's just that I didn't know anything about these things before. Xiaoya, if you want to deal with the corpse king and the dense high-level zombies around it, if the number of this crystal energy gun you said is small, it will not work. Zhai Fengcheng's eyes lit up and he raised new worries.

"Brother Feng Cheng, there are too many secrets in the headquarters of the Heavenly Wolf Army. The secrets of the Crystal Energy Gun are still only known to a dozen absolute high-level people within the Sky Wolf Army. I hope Brother Feng Cheng doesn't think about it too much. Actually, even I didn't know about it until a few days ago. It was my brother who was worried about my safety before leaving, so he gave me 100 of these guns for my guards. There is not a single unit in the other units. Lin Ya said a little embarrassed.

"Understand, understand, understand. I definitely don't think much about it. Zhai Fengcheng nodded like a chicken pecking rice.

As the patriarch of the Sky Wolf Army, starting from the Yanda Sky Wolf Detachment, Zhai Fengcheng knew that there were many mysteries within the Sky Wolf Army. But the boss Lin Chen also has a rule that if it is not for the news that he took the initiative to disclose, he is not allowed to ask and talk about it. If someone feels that the upper echelons are not honest enough with them, they can break away from the Sky Wolf Army on their own.

Therefore, Zhai Fengcheng was only slightly surprised by the sudden appearance of the battlefield killing weapon, and accepted it all.

In fact, the news of the crystal energy gun that Lin Ya knew was just what Lin Chen said. No one knew that this crystal energy gun was created by Lin Chen using the transformation of the seed world. If he hadn't been too worried about Lin Ya, Lin Chen might not have let this crystal energy gun come out on a large scale. Because in Lin Chen's estimation, the various units belonging to the Heavenly Wolf Army already had enough ability to survive this catastrophe.

"Xiaoya, how are you going to attack? How many people are needed? Zhai Fengcheng asked.

"I'm going to find the Corpse King first, and then launch an aerial strike on them. The effective range of the crystal gun is more than 400 meters. As long as we shoot at a height of 200 meters, the corpse king will have no escape. And zombies can't attack at such a high height. The height of their attack is up to a hundred meters. Lin Ya said.

"Air strikes? Xiaoya, there are a lot of zombie birds in the corpse group. And there are mutant birds......" Zhai Fengcheng said worriedly.

In any case, Lin Ya's safety must be put before annihilating the enemy.

Lin Ya smiled at Zhai Fengcheng's worries and said nothing.

Zhai Fengcheng suddenly realized.

"Yes, you don't have to worry about zombie birds and mutant bird raids. The hundreds of mutant eagles you brought with you are all menacing, absolute air king formations. There are so many swifts that can fight with you to protect you. Zhai Fengcheng said happily.

With powerful long-range weapons and air power, Zhai Fengcheng had almost no doubts about Lin Ya's safety.

"Xiaoya, let me join the attack, okay?" Zhai Fengcheng rubbed his hands and said expectantly.

Since Lin Ya did not have this kind of perfect crystal energy gun in the support materials provided to the Ice and Snow Division on behalf of the headquarters this time, Zhai Fengcheng wanted to follow Lin Ya to attack and experience this peerless weapon that made his heart itch.

"Brother Feng Cheng, I know what you're thinking. The elder brother said that this weapon will be slowly distributed to various units in the future. You don't have to be in such a hurry. Lin Ya said with a smile.

"Okay Xiaoya, you can let Brother Feng Cheng experience it in advance." Zhai Fengcheng said with a grim face.

"Okay." Lin Ya said a little helplessly.

There were about forty people who had followed Lin Chen since the beginning of Yanda. These people are now the veterans of the Sky Wolf Army. For these patriarchs, even Lin Ya has to give them some respect, and will not easily reject their requests.

Soon, the air force of the Sky Wolf Army rose from the ground and flew towards the east city gate. Lin Ya and her guards stood firmly on the eagle's back with the Perfect Crystal Gun in hand.

Zhai Fengcheng couldn't put it down and played with the crystal energy gun assigned to him, waiting impatiently to show his skills.

Because it was in a state of imminent battle, the eagle that the wolf king and Yu Yang were riding closely followed closely on both sides of the eagle that Lin Ya was riding.

Feifeng City is not large, with a diameter of less than ten kilometers. The Sky Wolf Air Force quickly reached the sky above the corpse group outside the East City.

Lin Ya and a few psychic powers let go of their psychic power to find the location of the corpse king in this direction.

After probing, they were surprised to find that they could not detect the breath of the Corpse King.

"The corpse king is alert. I'll see how long you can hide. Lin Ya didn't care.

At this time, thousands of zombie birds surrounded the air troops from all directions. Although the number of zombie birds that swooped over was huge, there were only three or five of them that had reached the sixth level of the first level, and only a hundred of them that had reached the fifth level of the upper rank. The others are all below the fifth level.

And there is no longer a fifth-level or higher in the Sky Wolf Air Force. Half is the sixth level beginner, and half is the fifth level upper. Lin Chen's resources on air forces are not a joke.

Facing the swooping zombie birds, Zhai Fengcheng was still a little nervous in his heart. Lin Ya and the others were peaceful. Along the way, the air force dispersed countless flocks of mutant birds. Among the flocks of mutant birds that were dispersed, there were many bird kings who had reached the middle level of the sixth level.

Compared to those mutant bird flocks, the zombie bird flock in front of them can only be regarded as a piece of cake.

However, there are only three or five of them who have reached the sixth level, and there are only a hundred of them who have reached the fifth level. The others are all below the fifth level.
