Chen Kai is forced to play the role of coolie at this moment. Although his power is not the most powerful, his manifestation is the most powerful. No matter from any angle, Chen Kai is very consistent with the word "Coolidity". Although Chen Kai strongly denies it, he is still arrested and then carried the rocks back and forth.

When Chen Kai was extremely miserable and was caught, the dwarves began to increase troops to the wall. At the same time, a magic crystal cannon was dragged and pulled to the wall by the dwarves. When the first magic crystal cannon shell was fired from the wall, the dwarves used rapid shooting to tell the undead that they would have to pay an extremely heavy price to step onto the wall.

However, the damage caused by the shelling is not very strong. Although the shells can cross the head of the Zhong Hammer Demon after being transported to the wall and go over the other party's head and will not be blocked by the Zhong Hammer Demon's huge body, the damage of these magic crystal cannon shells is mainly explosive power and shrapnel damage. For the undead, this damage can be ignored.

However, for the undead on the wall, this is their first time facing the dwarf's magic crystal cannon. At least this part of the undead is facing the bombardment of the dwarf's artillery. Although the artillery gun's artillery bombardment suppressed some of the undead, the guards on the wall quickly discovered another problem. It is these problems that caused the magic crystal cannon weapon to be completely kicked out of the defensive battle.

The dwarves tragically found that the magic crystal cannons they had high hopes were transported to the wall and each shot was required to remind the defense personnel in front. The narrow wall itself was very narrow and could not accommodate many personnel at all. At the same time, because less than one meter above the top of the wall was the rocky top of the passage, the shells could not be shot high. Faced with this situation, the huge magic crystal cannon was forced to kick out of the entire battle line, but the shells of the magic crystal cannon that were loaded with unstable compounds and exploded as soon as they hit became simple grenades in the game world.

Although this grenade is a little larger and the explosion efficiency is slightly lower, it cannot be thrown farther. The amount of three or four kilograms makes some players unable to throw such shells even twenty meters when they hold up such shells, and they can even be smashed outside the wall as stones. Players act as grenades, and after pulling the shells made of this unstable compound onto the wall, they start to throw them out of the wall desperately, regardless of whether the shells hit the target. However, this way

The method of using shells as grenades has played a certain role. At least the dwarves do not need to avoid shells fired from behind, nor do they need to give up positions for shells and be exploited by the undead. At the same time, the attack speed of grenades is much faster than the speed of launching shells by magic crystal cannons. The only problem is that the dud rate of using shells is slightly higher. Although as long as there are shells around, the splashing shrapnel will detonate those dud shells, there will always be some fish that escape the net.

However, for those who are defending, the thrown shells are still useful, at least they seriously reduce the speed of the undead. Although the impact force produced by the explosion shells and the flying shrapnel cannot kill the undead, they will still cause some damage to the opponent. If the explosion is hit on the front, the damage caused will seriously injured the undead warrior or even be directly killed.

For the dwarves on the city wall, or not just dwarves, but other guards, sticking to the wall is a chore. In fact, there is nothing more difficult on the entire battlefield than sticking to the wall. After all, the warriors on the wall not only have to face the threat of the dwarf death knights, but also have to face the dangers of the undead bell hammer demon and those undead warriors. Even the holy-level strongmen like Arnault, the holy dwarves also need to face the threat of death, because the undead dwarves can retreat behind and hide when they can't hold on. However, the guards on the wall cannot easily retreat. One step back means that there will be an additional enemy on the wall, and if the enemy step on the wall and gain a firm foothold, the battle behind will be more difficult.

Therefore, even if the guards on the wall are seriously injured, they dare not or cannot take a step back. If they want to retreat, they must retreat without someone to replace them. Among the people who can retreat in this way, there is absolutely no part of the Saint-level powerhouses such as Arnau, because for such an existence, retreating and resting is a very luxurious thing. At least until now, Arnau has not even drunk a sip of water. At the same time, his originally very abundant Dou Qi has consumed at least one-third. This is very rare for a Saint-level powerhouse, because according to their level Dou Qi recovery speed, Dou Qi is almost continuous in ordinary combat situations, but when they use powerful moves in battle, the recovery speed of Dou Qi still cannot keep up with the consumed speed, which will cause the Dou Qi reserve to drop rapidly.

For Arno, the consumption of fighting energy is not the main reason for his fatigue. What really makes him tired is continuous fighting and high-intensity confrontation. At this moment, the hair on his body began to turn gray. In addition to the reason for being contaminated with a lot of dust, another reason is that he is constantly attacked by the power of death. Even if Arno's strength is close to the Sanctuary of the Ensign, he still cannot completely ignore the clarity of these death powers, especially during the battle, he cannot completely expel the dead energy attacked by the Dwarf Death Knight's weapons from the body. These death powers are accumulated in Arno's body, and it keeps weak over time, and the hair on the surface of his skin is also gray. Chen Yi can easily treat such gray defeat. Because the main reason for these hairs is the death power remaining on the surface of Arno's body, which only requires a little sacred power baptism to be easily removed.

Unfortunately, Chen Yi was busy treating the wounded under the wall at this moment, and she had no time to release the power of the halo. At the same time, due to the lack of materials to build the altar, her halo cannot last for a long time. If she spreads the halo, she can only consume Chen Yi's own magic. Although Chen Yi has a source of faith that can quickly replenish magic, relying on this method does not mean that there are no side effects at all. Although the side effects are relatively small, continuous use will still seriously consume Chen Yi's spirit and make her depressed. Therefore, Chen Yi did not use the halo to help the dwarves on the city wall. Of course, another reason is that her magic is now consumed a lot of magic power just to treat the wounded. Just to save the wounded, she is still recovering.

When Chen Kai put a rock weighing more than 400 kilograms flat on the ground, his only idea was to find a place to rest. Although such a rock would not damage his muscles, the continuous use of power explosion to carry the rocks still made Chen Kai's arm extremely sore and soft. This high-intensity work was something Chen Kai had never experienced before. Although Chen Kai had used a metal stone lock weighing more than 500 kilograms to train the power explosion skill, there was no such thing as it was now. Fortunately, after a period of exercise, Chen Kai found that his power explosion skill had lasted longer, or that the muscles on his arms had begun to gradually adapt to the long-term stimulation of power explosion skill.

Although the use of the entire skill still cannot last too long. At most, it will be extended from the original few seconds to the current ten or even twenty seconds. If the arm muscles will be sore and painful for more than half a minute, and maybe even muscle tear will occur, it will be much stronger than if it will be sore for a few seconds in the past. Of course, this improvement was obtained by the coolie. In more than ten minutes, Chen Kai transported a full 80 rocks with a weight of more than 200 kilograms. If it were an ordinary player, he would have been exhausted. However, Chen Kai was the arm muscles.

It's just sore, and the physical energy consumption is not particularly serious. It's just that a 200-kilogram rock is only 30 to 40 cubic centimeters, and the total of more than 80 rocks is only 20 cubic meters. In other words, the stones carried by Chen Kai alone increase the thickness of the wall by nearly one meter. Although these rocks will be squeezed by soil element spells to increase the density of the rocks, and at the same time reduce the gaps between the rocks and even make it completely free of gaps, the last twenty cubic meters of rocks built half of the wall.

However, Chen Kai is not the only one responsible for carrying rocks. Hundreds of players were pulled to do this work, but they did not only need to carry around a hundred meters like Chen Kai, but needed to carry the rocks from hundreds of meters or even thousands of meters away. Some of these rocks were removed from the houses, and some were simply dug from the ground. The roads and houses in the entire lava city were dug in a mess by dwarves and players, and it seemed that they had been looted. Of course, if they were real robbers, they would not be stupid enough to rob the buildings in the city, let alone dig the rocks on the ground, unless they were made of gold.

With the hard work of the players, the thickness of the wall increased by ten centimeters per minute. When Chen Kai sat down and rested, the wall that was only more than two meters thick had grown to more than three meters. Four or five warriors could stand in parallel on the thick wall. At the same time, the street began to widen behind the wall. The width of the wall built by the dwarves gradually increased. Two up and down steps were added to both sides of the wall, so that the guards could go up and down the wall from both sides to avoid delaying the thickening work of the wall behind.

However, the construction of the wall did not stop. When Chen Kai sat down to recover his strength, the second wave of players began to join the construction work. More than three thousand players carried more rocks like ants and built them behind the walls. The dwarf mage squeezed his magic to compress the rocks and strengthen the strength of the rocks and bonded them to the rocks in front. Now the dwarfs need to increase the thickness of these walls to five meters, and then build a taller wall behind the walls, at least the height should reach more than four meters. The only purpose of this is to retreat to the back wall when the front wall cannot stop the demons. In this way, the dwarfs have a new defensive position and do not have to worry that the collapsed wall will affect the defensiveness of the city wall.

In fact, this wall is a revision of the wall built around the exit of the street in the original plan. The only difference is that the position of the wall has been moved forward. But the ultimate goal is to block the demons in the street and disagree with them to continue to spread to the remaining city of Lava City. According to Thram's idea, it is necessary to block the demons and the undead in this street, and prevent them from continuing to attack and protect the Dwarf Palace.

At the same time, as the players not only resurrected the dwarves' troops could mobilize, but Thram did not directly throw the players into the battle, because he knew very well that once these newly resurrected players might send materials to Ratamitheus to the undead troops. Therefore, most of the resurrected players were incorporated into the coolie camp, which is a transport brigade specially used to build fortifications. Chen Kai unfortunately became the captain of the transport brigade.

Carrying huge rocks to build them under the wall, then turn around and continue to carry the rocks to the place where the rocks are piled up. The rocks that were originally used to build the surrounding walls were dismantled by the dwarves and placed behind the new walls to build them. This reduced the workload a lot. After all, the dwarves had prepared some rocks to build the subsequent walls at the beginning. And these rocks were very huge.

In just half an hour, a new taller wall was added behind the wall, which was as thick as two meters and four meters. At the same time, behind this wall was a small wall that was more than three meters thick, which was specially used to keep the garrison troops. When the wall had just been built with a layer of thickness, several dwarf gunners could not wait to carry the magic crystal cannon on his shoulders and hands on the wall. After a slight adjustment, they fired the first shell towards the front line where the battle was fierce and fierce.

Although due to the shooting world, the dwarf's shells could only land less than two meters ahead of Arnold and his team. However, at least they could kill the undead here, reducing the pressure on Arnold and his team's guards again.

In just a few strokes, these magic crystal cannons were kicked off the wall again. The dwarf gunners faced unemployment again when they just found employment. Because the power of the magic crystal cannons was really not enough, and the firing speed was too slow, it would be better to just use the shells as grenades. The most important thing is that at this moment, Arnault and the others, that is, the guards on the street walls, had begun to retreat. Of course, they were not voluntarily retreating, but were forced to retreat backwards. Because the Zhong Hammer Demon in front kept dismantling the walls, digging the place where Arnault and the others landed.

In this situation, the guards could only be forced to retreat. If it weren't for the new walls that were constantly being built behind, they would probably have no place to stand. The six bell hammer demons were very fast to pull the walls. They could almost pull down the rocks weighing hundreds of kilograms with one hand, and then throw them backwards or even throw them directly into the walls as a rock to hit the guards.

Arnor was almost hit by the rock that suddenly flew over several times. It was a miracle that the dwarves could last for such a long time. In order to prevent the Clock Hammer Demon from plucking the rocks, the dwarves were preparing a secret weapon. It was actually not a secret. The dwarves set up a huge crucible on the towering wall behind, which heated extremely hot lead water. Once the Clock Hammer Demon began to pluck the rocks under the wall, the lead water would pour down. The Clock Hammer Demons that would be hot caught fire all over the body, and at the same time, the lead water could also penetrate into the rocks to strengthen the wall.

The only question now is how long Arnold and the others can hold on. For Thram, Arnold and the others will naturally hold on as long as possible, but the current situation is that the group can no longer hold on. Whether it is Arnold, Drake or Fravaz's physical fighting spirit has reached its limit, and even those dwarf strong men are almost unable to hold on at this moment. Although they have killed thousands of undead, they are often entangled by several dwarf death knights or hit by several clock hammer demons.

But if there were no accidents, Arnault and the others could hold on for a few more minutes. But Ratamitheus, who had been recovering from the rear until now, could not sit still. A very simple battle that he thought was like this made him very annoyed. In his eyes, the dwarfs were just a betrayal dog. Such a thick city wall and complete defense could not stop the footsteps of their demons. It was too ridiculous to rely on this simple wall to block Ratamitheus' army. But such a ridiculous wall blocked him for nearly an hour and almost killed him. Therefore, he was very angry at the moment. The longer the dwarves insisted, the more annoyed him, the more annoyed him, as if they were slapped on his face.

Therefore, although the bones on the body have not completely healed, Ratamitheus, whose soul fire has recovered most, put down the frozen Samori and appeared again in front of the dwarf's wall. It was also a gray-white death shock wave, but this time his target was no longer the wall, but the guardian on the wall. Arno's huge body seemed to be the best target for attack in Ratamitheus, so the death shock wave exuding the breath of death rushed straight towards the Taurus who was waving the iron ring sword.

At this moment, Arnault did not find a power of death pounced on him. Because all his energy was devoted to dealing with the attack of the dwarf Death Knight. By the time he discovered it, the gray-white death shock wave was approaching. The only thing Arnault could do was raise the iron ring sword in his hand to block his chest, and then he was bombarded out, and his huge body was directly bombarded several meters away. It hit the wall behind and smashed it and shook the entire wall. (To be continued.
