When more than 500, six or seventh level Aboriginal earth element casters carried out restoration of the city walls on the defense line, Chen Kai had already asked Drake to return to Berkner Town with a quick horse and mobilized new troops to replenish the stretched forces in the underground world.

It can be said that this time the Bone Demon attack directly hit the weakness of the underground world defense line. If he launched an attack one day earlier, the hundreds of earth element casters who moved to the fourth line of defense would be recalled in a short time. Even yesterday night, most of the strong men in the temple were patrolling the underground world. Just to welcome Gavalon and the others, Andre and his group would leave the underground world.

At the same time, if Ratamitheus attacks for another day, then the Dawn Temple troops on the defense line will add a Dragon Knight troops from the Dawn City. However, the attack time of the White Bone Demon was so coincidental that it seemed like fate was arranged. It was just as early or late that it happened to appear in front of the players when the defense line was the thinnest. Two days ago, all the black dwarves happened to withdraw from the underground world. This is also the reason why there were almost no dwarf warriors from head to toe in the battle, although the dwarves were still some of them stayed in the underground world.

But most of them stay in the magic crystal cannon room or in the rear. Of course, the rear is not the rear of this line of defense, but the rear of the second and third lines of defense helps Berkner to build a defense line to block the destiny and demons. At the same time, these dwarves responsible for the construction themselves are not strong in combat. Most of the powerful dwarves are gathering in Kelda City in the north of Berkner Town. The dwarves decided to build Kelda City as their homeland before finding a new settlement.

Chen Kai was very happy about this situation, because in this way, the pressure on Berkner Town by the dwarves by the dwarves and the dwarves in the north was completely borne by the dwarves, or at least a large part of it was borne by the dwarves. At the same time, because the dwarves temporarily used Kelda City as a nest, part of the land occupied by Chen Kai and the others would not be invaded by the dwarves. The only problem was that Chen Kai had to take out part of the grain produced and distributed to the dwarves. But even so, Chen Kai felt that it was a profit. After all, it was very cost-effective and worthwhile to exchange some of the disposable food for a stable grain-producing area and a more stable ally from any perspective.

Although Chen Kai could not use this method to tie the dwarves firmly to Kelda City. After all, for the dwarves, these foods cannot fill their stomachs and intestines. The dwarves still need to constantly purchase food from the outside world to feed their more than 100,000 tribes. If there was no chaos in the Hansting Empire, the wealth accumulated by the dwarves when they evacuated the Lava City could be enough for them to eat for several years, but now they can buy enough food for them to eat for a year and it is quite good. Under the rampage of the drow elves, the food production of the entire Hugodi Territory was almost on the verge of collapse. It could only guarantee that the local food attacks of the Hugodi Territory are now entirely based on the supply of the southern territory. The food price of the entire Hugodi Territory was almost three times that of Chen Kai before the Hugodi Territory. The food price of the other cities in the north was even higher than that of the town of Berkner.

However, for Chen Kai, what he needs to do now is to supply the players' food, because he does not provide excess food to the dwarves at all. At the same time, because there are more than a dozen flying dragons, Chen Kai's food not only has not become loose because of not supplying the dwarves, but has become even more nervous. All flying dragons eat meat, and the supply of meat in Berkner Town has always been extremely tight. Even Chen Kai, as the lord, cannot guarantee that six tons of rice will be meat for two days. Most of the time, meat is for two little guys.

Food. In order to entertain Galvalon and others of the Dragon Knights, Berkner Town has consumed its fresh meat reserves in the past half month. Chen Kai had no other thoughts than to recite the word "scammer" in his heart. In the end, he could only helplessly wave gold coins to buy more beef cattle or pigs from the surrounding towns. Fortunately, Chen Kai did not have to bear all of these foods himself. If the expenses used to support the Dragon Knights were all required to be borne by Chen Kai, then Chen Kai probably wouldn't need to do anything else but just raise pigs.

Of course, everyone on the entire defense line is not in a mood to eat. Xu Fei, who is in charge of logistics supply, only thought was to breathe a sigh of relief. Because if it is necessary to immediately supply the food in the underground world, it is estimated that it will be impossible to complete it in less than half a day. Of course, what Xu Fei is more worried about is not the food problem, but the magic crystal ammunition that has been consumed in less than half an hour. There is no magic crystal mine in Berkner Town, and there are many magic crystal mines in the underground world. Unfortunately, these minerals are all buried deep under rocks or magma. The only way to replenish the magic crystals used for firing for the magic crystal cannon is to pay for it.

Chen Kai was standing under the city wall at this moment, watching the spent magic crystals pile up. The color of these magic crystals is pure like transparent glass melted. But not long ago, they still had very beautiful colors and magical magic crystals. Unfortunately, thousands of magic crystals were consumed in less than half an hour. At the same time, nearly five million worth of gold coins were evaporated. Each of the magic crystals purchased from the dwarves as a friendly price is as high as five thousand gold coins, and the currency in reality is 5,000 yuan. The main reason these magic crystals are medium-quality magic crystals, but they are basically stocked for a long time. If it weren't for this, Chen Kai wouldn't have bought one for 5,000 yuan, and he bought several thousand yuan at the same time. Even if he and Thram had a good relationship, it would not have allowed the dwarves to sell magic crystals so low.

Seeing the nearly five million gold coins that were evaporated in less than half an hour, Chen Kai was in a very bad mood. Of course, no matter how bad he was, he could not reveal that he had appeared. At this moment, there were people on the city wall who were in a worse mood than him. In the end, Chen Kai threw a piece of white abandoned magic crystal on the ground. Then he helplessly asked Xu Fei to prepare another batch of magic crystals through the communicator. Of course, the new magic crystals would never be able to buy at a friendly price. Chen Kai could only buy from the market through merchants. And Chen Kai estimated that when these magic crystals arrived, the battle in the underground world would no longer be known as what the situation would have been. Before the new magic crystals were purchased, Chen Kai could only do it to transport the prepared magic crystals from the back line of defense. These magic crystals quickly filled the magic crystals into the magic crystal cannon room where the gun barrels gradually cooled.

Although the undead has retreated at this moment, no one knows when they will make a comeback. At least Chen Kai feels that if he is the commander of the undead, he will definitely make a comeback soon after discovering the extremely fragile resistance of the defense line, unless there is something in the city wall that he is more afraid of. However, Chen Kai looked around and seemed to be unable to find anything besides Andre and the others that could make the undead army afraid of.

But in fact, the Bone Demon was not afraid of Andre or Gavalon, nor was it afraid of Fickel, the flying dragon. In his opinion, Fickel was just a material used to make the bone dragon at any time. The reason for his temporary retreat was that the loss of troops was too large. Although more than 30,000 undead spirits had the Bone Demon leading the battle, resulting in a reduction in combat losses, under the bombardment of the magic crystal cannon and in the end to retreat, the Bone Demon lost nearly 3,000 undead troops and a death knight in this battle. For the Bone Demon, the low-level undead spirits lost were nothing, but the more than 50 dead bone demons and a dwarf death knight were the ones he felt most heartbroken.

The Dead Bone Demon was not cultivated by him, even if he lost it, he would not feel too heartbroken. However, the Dwarf Death Knight was the core combat power he was preparing to cultivate. The original Dwarf Death Knight was only four, which made the Bone Demon in a bad mood.

"Damn humans! Damn god believers! These bastards who should be cursed! My death knights!" The bone demon's head was constantly cursing, but his face was still very average on the surface, as if he was thinking about a new round of attack strategy. At the same time, Robert, who was commanding hundreds of hellhounds in the back, felt a cold gaze swept across his body from time to time. The feeling of being peeped made Robert very unhappy. But people had to bow their heads under the eaves. Even though Robert knew that the gaze came from, she finally chose to ignore it. Of course, while ignoring her gaze, all her hellhounds gathered beside her to block the gaze of the bone demon's spying.

"Tsk haha! Do you want to stay out of the matter? Don't worry, you will never escape from my palm!" Looking at the blocked huge body, the white bone demon suddenly smiled sinisterly. He had already thought of a very vicious idea in his mind, and this idea was definitely not a good thing for Chen Kai and the others who defended the city wall.

"Robelt! I need your efforts! Take your children with you and prepare to set off! My Death Knight will open the road to the city wall for you, and what you need to do is to help me restrain the most powerful god knight on the city wall!" After silence for a long time, the voice of the bone demon suddenly rang in Roberto's ears. The four hellhounds who were resting on the ground did not move, but under the continuous call of the bone demon, she was still unable to stand up from the ground.

"Ratamitheus! Don't command me at will! Believe it or not, I'll remove all the bones in your body!" Although the body has not been completely restored, Robert's extremely powerful power can still fight against the bone demon.

"Robelt! This time I'm not commanding at will! I'm making a deal with you! Did you see it? This is the blood of Edmons, the dragon of the dead earth! Under my modulation, this blood can quickly recover your injury. I think as long as your injury recovers, you can exert all your strength! In this way, I think even under the siege of those god knights, you are fully capable of protecting yourself, right?" Ratamitheus slowly took out a bottle of violet-colored bottle from his dimensional space, and a trace of golden blood flowed into the bottle and exuded an extremely terrifying power.

"Is that so kind!" Robert is not a fool, she could naturally feel the liquid that was very attractive to her in the bottle, but her heart was filled with worries and fear of being fooled by the bone demon.

"Of course! Don't forget that we are on the same boat now! If I don't help you, then who else can I help? Only by destroying these enemies in front of us can we leave this dark underground world or do you want to defect to those garbage huddled into the dark underground?" The garbage mentioned by the Bone Demon is naturally the demons such as Qiqigela who is staying in the demon's nest at this moment. Looking at the somewhat hesitant Robert Bone Demon had to add the power of spiritual seduction in his language.

"Hmph! Maybe those trash will make you easier to talk to! At least they will not turn my descendants into undead!" Robert shook his head slightly and got rid of the spiritual bewitching of the bone demon, and his vigilance towards the other party was even more obvious in his eyes.

"But they will turn all your offspring into food!" The soul fire in the eye sockets of the bone demon became more and more intense. He was not surprised that Robert had escaped his spiritual bewitching, because this was originally a planned thing.

"Hmph! Who knows! Throw things over! I don't want your dirty bones to smear my territory! I don't want my children to gnaw on your body as bones! That will make them worse!" Robert still couldn't put down his desire for the bottle of liquid, because there was a voice in her heart and told her to drink the bottle of liquid.

"Remember your choice! Robert. If you betray our contract, then I will send you directly back to hell!" Ratamitheus shook his claws and threw the bottle in his hand directly at Robert. He was not worried that the other party would not drink the bottle of liquid. Because the bone demon did not tamper with his hands, the place where he really tampered was other places, and had already buried his own dark chess.

Gently bit open the cover of the bottle with his mouth, Robert's head, which had been hanging down, suddenly emitted amazing power, and he grabbed the bottle uncontrollably and drank all the liquid inside. When the violet liquid entered Robert's mouth, the head that had been injured by Bass' slash suddenly burned a black and red flame. At the same time, the four heads screamed at the same time, because although the liquid entered the mouth differently, the power of the final digestion and transformation was the same. A trace of dragon power from Edmons slowly merged into Robert's bloodline. The most important thing was that other things mixed in the liquid began to recover from Robert's injury. Her injured head began to slowly restore to its original state. Finally, with four roars that sounded at the same time, Robert's body completely recovered.

"This feels really good!!" Four sounds sounded at the same time appeared in the center of the Hellhound group. The huge body of the four Hellhounds, which were more than six meters tall and more than fifteen meters long, began to slowly emit terrifying power outward. Under the influence of the liquid, Robert's originally extremely small fourth head had grown from less than ten centimeters to more than thirty centimeters. The most important thing was that after the head grew, the death she mastered told that the extremely strange magic range had increased by nearly three times, from less than one meter to less than three meters now.

"I think I can go for revenge now!" "Yes! Kill the user of the divine power!" "No! I want to eat him!" "Yes! Let him become a nutrient for our body!!!" Robert's voice began to sound, and the burning soul fire in the eye sockets of the Bone Demon also began to become very bright, because he knew that the first step he buried had already taken effect. Although he did not add curses or other things to the liquid, he added some manic potions, which could make the user more warlike and revenge stronger, and this was exactly what the Bone Demon needed.

"Then let's go! Children! Let's kill all humans and eat them!!!" Eight extremely bright red eyes emitted a strong murderous aura. Under Robert's roar, more than 100 hellhounds burst out with roars one after another. At the same time, the white bone demon's sinister smile was mixed with. Just as the hellhound began to run wildly, more than 20,000 undead slowly began to move again, and launched a tide-like charge towards the defense line that had just recovered.

When the gray-white black line appeared in the player's vision again, Chen Kai was directing the player to strengthen the crossbow on the city wall and repair the crossbow strings that had been destroyed in the battle before. The dragon knights gathered under the city wall gathered all the flying dragons. They knew very well that the terribleness of the Dead Bone Demon, so the dragons would not be thrown into the battle before completely destroying the Dead Bone Demon. However, the alarm bells passed on the city wall made these dragon knights feel extremely angry. Of course, this anger was not interrupted by communicating with their mounts, but the anger of wanting to kill the undead to avenge Sean.

More than a dozen dragon knights jumped onto the low city wall at the same time, but they were soon driven down by the extremely dense white bone crossbow arrows. The white bone demon told everyone the fact that he was coming again with a powerful wave of coverage. At the same time, he also hoped to declare in this way that he would be the winner of the battle. Hundreds of thick crossbow arrows broke through the air and flew hard through the city wall to the rear. Looking at the crossbow arrows falling on their heads, Chen Kai's face looked a little ugly because he found that the bed crossbow he had just repaired was destroyed by the crossbow arrows again.
