"Chirp!!" The magic crystal cannon shells emitted a scorching heat, and at the same time, they almost broke through the sound in the process of flying. The whistling sound caused by slicing through the air was very harsh, but as the cannonballs were about to fall into the huge army of undead dwarves, gray-white protective barriers suddenly rose above the dwarves' heads.

With the power of flares, players on the walls can use the Eagle Eye telescope to see the undead dwarven mages raising their staffs. More than a hundred undead spellcasters formed a huge group of dwarven necromancers, and protective barriers blocked the landing point of the magic crystal cannon shells. Blocked by these protective barriers, the Crystal Cannonball that hit the magic wall exploded, and the huge light made the player holding the Eagle Eye telescope almost blind to the bright light at that moment.

Although the protective spells arranged by these undead spellcasters were instantly torn apart by the impact of the explosion, the cannonballs that would have landed in the middle of the undead troops were blocked out, and the terrifying flames and impact from the explosion only bit a small hole in the periphery. A dozen cannonballs did less than a hundred undead dwarves, and this kind of attack really made the dwarves on the fence a bit depressed.

Of course, no matter how depressed the dwarves were, they didn't slow down in the slightest in loading their shells. Almost as soon as the first round of shells had exploded, the second round of shelling shot out of the Crystal Cannon, which had just finished retracting its barrel. The whistling cannonballs swooped down on the army of the undead who had released the magic barrier, and this time the number of shells was even larger, as nearly fifty magic crystal cannons of large and small calibers were fired at the same time across the entire wall. Although there are only twenty-one large-caliber magic crystal cannons in it, the others are all small-caliber magic crystal cannons that can only shoot unstable compound shells.

Although the power of these unstable dìng compound magic crystal cannon shells is a bit small, when twenty or thirty shells fall in one place at the same time, the explosion caused is still very considerable. The most important thing is that this kind of small-caliber magic crystal cannon dwarves have produced a lot, and the first wave of small-caliber magic crystal cannon shells is just to test the effect. When the second wave of cannonballs fired, all the dwarven gunners had a hideous expression on their faces. A full hundred small-caliber magic crystal cannons were reloaded in less than twenty seconds, and the flames of the cannonballs that were fired quickly rose at the same time, and the continuous sound of shells ejecting was almost in a line.

Behind these magic crystal cannons, the originally very beautiful dwarf queen Vivichira described her whole person as withered. In order to avenge her father, she stayed up for two days and one night to improve the flaws of the unstable dìng compound shells. Not only did it increase the power of the shells by 20 percent, but it also increased the range of the shells after continuous firing. Most importantly, she increased the explosive stability and explosive power of the unstable compounds, so that the shells would not explode on the slightest impact. The most important thing is that this transformation is not complicated, and it also increases the storage time of these unstable shells several times, from the original maximum storage of one week to nearly two months. So the nearly 500 shells that had been stored and were about to be destroyed were brought to life again, and of course they would not have been destroyed even if they had not been modified, because they were now useful.

Of course, the total number of shells stored by the dwarves at this moment is definitely more than a thousand. Therefore, even if hundreds of small-caliber magic crystal cannons were fired rapidly, the number of shells did not drop quickly. The only problem is that the errand of transporting cannonballs is very difficult, and tens of thousands of players acting as transport brigades can only barely supply the dwarven gunners who have become mechanically operated. At the same time, more players are holding the cannonball making drawings given by the dwarves to make cannonballs in the rear, although the dwarves and the players are now in a cold relationship, but in the face of the undead attack, the dwarves can only take out the cannonball making drawings and give them to the players to make zuò. While the player is only responsible for the reloading of the shells, the shells and the most important parts of the fuses are done on the ground by the Dwarven Craftsmen.

Every hour, player transport troops arrive on the ground with thousands of shell casings and fuses placed in the backpack space. Give it to the players to make cannonballs and send them to the wall. In less than two days, the dwarves had accumulated more than 10,000 shells, and of course this number of shells had basically exhausted the town of Burkna and the dwarves with the last vestiges of metal. Now even if Burkner Town wants to repair farm tools, there is no iron ore at all, although the player miners in Burkner Town are digging holes to make money, because the price of iron ore in the entire Burkner Town has skyrocketed by 30%. If you don't dig more to make money at this time, they won't have the opportunity to make this money. If you wait until iron ore shipments from other places arrive, then the price will return very quickly.

While some players have any as long as the battle in Lava City continues, then the trend of metal ore price increases will continue. So he chose to hoard rather than sell, but Chen Kai had already contacted Lin Lei. Purchased thousands of tonnes of ore from the other side at a price 10 per cent higher than the benchmark price per tonne of metal ore. As long as these ores are transported, the shortage of ore in Burkner Town will be greatly alleviated.

Perhaps it would be more cost-effective to ship metal ingots directly than to transport ore, but the key problem is that ore is far cheaper than metal ingots. Under the control of the Dwarven Tinkerer, the Dwarves can refine at least five percent more metal ingots than the player, and can also refine the rare metals in the ore slag. If the dwarves can keep the demons from trapping them under the abyss of gems, then Chen Kai may be able to rely on the dwarves' refining techniques to continuously accumulate more metal ingots, and rely on the difference in the price generated by refining metals to make profits. Although this method of making money proved to be almost viable, as very few of the smelted ingots were eventually sold. Most of it is consumed internally.

With the support of the town of Burkner, that is, Chen Kai's empty pockets, the dwarves had enough shells to store enough for these small-caliber magic crystal cannons to hit at least a hundred rounds. According to the calculation of three to four shots per minute, it is possible to shoot for at least twenty-five minutes or more. Of course, generally speaking, after firing about fifteen rounds, these small-caliber magic crystal cannons need to be stopped firing and cooled down.

However, a dozen rounds of artillery fire had already created a dozen huge gaps in the approaching undead dwarf troops. Although these magic crystal cannon shells were intercepted by those undead dwarf casters, the continuous number of attacks combined with the power of the simultaneous explosion of the cannonballs caused the undead dwarves to suffer heavy losses. The dwarves on the wall were extremely happy that there were only a few of the thousands of undead dwarf troops left after the heavy shelling.

"That's not right! Why is there only such an army of attacking undead! Chen Kai looked at the extremely thin undead troops in the distance. He raised the Eagle Eye telescope in his hand to observe, and was shocked to see that the undead who looked neatly equipped were actually broken garbage. At the same time, the dwarven spellcasters who were originally hidden in the undead army are slowly retreating, and now these leading dwarven undead are completely outcasts who attract the fire on the city wall, the purpose is to let the dwarves expose the defenses on the city wall. Apparently the purpose of the undead has been achieved, and the dwarves are carrying out a frenzied attack on these undead dwarves because the corpses of their ancestors are defiled. Dense explosions destroyed almost all the bones of the undead dwarves, making them all complete. When the last few undead dwarves were shattered. The dwarves on the city walls celebrated with great joy. But soon they couldn't be happy, because the dwarves also gradually appeared new undead, and this time there were more undead troops on the streets, and there were some engineering weapons mixed in.

Don't think that Latamicius, as the undead demon lord, will only use the undead army frenzy to attack, in fact, if it weren't for the lack of resources, Latamicius would definitely be able to make even more terrifying weapons of undead warfare. This time, due to the abundance of time, more than a dozen bone ballistas mixed with metal and wood appeared in his troops. These bone ballistas were unusually large, three or four meters wide and five or six meters long. The white crossbow arm is made of more than a dozen huge white bones. But don't think that the bolts fired by these arms will be very powerful. When the bone ballistas began to shoot thick bone arrows at the walls, the dwarves knew the purpose of their first attack and the power of the bone bolts.

The whizzing crossbow bolts swooped directly at the dwarves' crystal cannons, although the dwarves fought back at the same time as the opponent attacked. However, the bone crossbow machine protected by the white bone demon Latamicius had hundreds of undead dwarf spellcasters was not destroyed by the cannonball, but the falling bone crossbow arrow directly killed more than a dozen dwarven gunners, and at the same time pierced a large-caliber magic crystal cannon.

These giant bone crossbow arrows were so sharp that even a shard of an arrow slash on the ground could make a shallow mark on the metal wall. When the undead's second round of crossbow bolts swept over. The deaths and injuries of the dwarves on the wall were even worse. Although the small-caliber magic crystal cannons can be quickly transferred, those large-caliber magic crystal cannons need hundreds of people to move after they are placed. After a few rounds of crossbow attacks, there were less than ten large-caliber crystal cannons left, and this was due to the fact that these crystal cannons were hidden behind fortress-like rocks. However, these magic crystal cannons hidden behind the fortress-like rocks were not pleased, because the rock turrets in front of them had been bombarded with huge bone crossbow arrows that continued to fall, and one of the fortress turrets was directly pierced by a huge crossbow arrow, and the extremely sharp bone arrow almost shot through one of the dwarven gunners inside.

In the face of the frantic attack of the army of the undead, the dwarves on the city walls were beaten without any temper. Although Latamicius does not have the Legion of Little Devils as a ranged fire aid. But he has his own way of supplementing it. However, although the power of the white bone ballista is powerful, the consumption of those extremely sharp white bone crossbow arrows is very huge, usually it takes hundreds of undead bones to make such a white bone crossbow arrow, these rounds of attacks have exhausted the white bone crossbow arrows accumulated by Latamicius, but such an attack is enough for the dwarven city wall that is completely dumb.

Seeing the miserable appearance of the dwarves on the wall, Latamysius waved his hand and kept the last few bone bolts. Then the huge undead army began to move slowly towards the wall where the dwarves were, and six death knights with frost power scattered all over their bodies rode their two-headed hellhounds and led the huge undead army towards the city wall. More than 30,000 undead troops formed a huge gray attack line and rushed out of the narrow streets. Although the dwarves have placed several small walls along the way to prevent the undead from advancing quickly. However, under the impact of several huge bell hammer demons, these small walls were breached, and it was only a matter of minutes.

Although the dwarves were well aware of the importance of wall defense, in order to leave enough firing range for the magic crystal cannons on the city walls, the walls built were very low, only more than two meters high. The two-meter-high wall had no effect at all in front of these Hammer Demons, but the explosives buried under the wall made the Hammer Demon suffer a lot of losses from the frantically advancing Hammer Demons. It's just that the shock wave from the explosion can't deal a devastating blow to these bell hammers, and the effect is to cause Latamysius to lose thousands of undead troops. But at this moment, the White Bone Demon, who had more than 30,000 undead troops, would not even frown at such a loss, although he had no brows and no muscles.

However, for the dwarves, they felt extremely anxious about each section of the wall being breached, even if the undead attack slowed down later due to the injuries of a few bell hammer demons. But the other party also began to learn to be obedient, and no longer forcibly crashed into the wall, but chose to climb over it. Of course, dwarves aren't stupid either. They are well aware of the fragility of the walls they have set up, so they are not meant to block, but only to plant explosives. Although the Bell Hammer Demon will not actively detonate without hitting the wall. But that doesn't mean that the dwarves themselves can't detonate the explosives in the walls. In order to prevent the detonation system from being damaged, the dwarves arranged dozens of detonation lines, but in the end, several of them had problems under the bombardment of the bone crossbows.

But eventually, when tens of thousands of undead troops crossed several walls, the dwarves pressed the detonating crystals. Bursts of magic shot out with the angry feelings of the dwarves through the pipes of slender Mithril threads. Eventually, a small magical explosive device buried in the wall. The tiny magic power eventually turned into a huge source of explosions, and when the continuous explosions appeared in front of Chen Kai, his only choice was to raise his shield and shrink himself under the parapet on the city wall. In fact, it was not only him who did this, but all the players in the entire city wall who were ready to participate in the defensive battle, because soon the sound of stones being smashed could be heard from the shields they were holding, and even some of the unlucky players were directly smashed to death by several huge flying rocks.

Chen Kai was also hit by several rocks. However, he was lucky, and he smashed the rock of the shield at the maximum, and the largest was no bigger than a fist. Although the time when it flew out due to the explosion was very high, because of the method used by Chen Kai, the shield was placed at an angle. The shield held high just formed an oblique angle to the flying rock, and the flying rock smashed against the shield without causing him much damage, and after a heavy bullet, it flew out behind the wall. As for whether it will hit people after falling behind the city wall, Chen Kai doesn't care, and at the same time, there are other things that fall to the city wall besides stones, such as bones that are thrown out or something.

However, the dwarves' long-prepared blasting attack did not cause any damage to the undead troops, although Latamicius was still very stunned and even annoyed by the dwarves' counterattack. But in the eyes of Robert behind him, this qiē was all pretended by Latamicius. It was well aware of the power that the White Bone Demon had accumulated now, and although the dwarf's attack had destroyed thousands of troops of the White Bone Demon, it was still a little far from the real broken Cheng Dù.

Don't look at the beginning, Latamicius sent the dwarven death knights to attack, but not many of the undead troops who crossed the wall were the core of the bone demon troops, and they were all improvised consumables. The real core force was barely damaged, and perhaps the other core forces did not advance except for the initial injury to the bell hammer demon, who attracted the attention at the beginning. The smoke from the explosion blocked the dwarves' vision, and the dim environment after the flares disappeared made it impossible for the dwarves to judge the strength of the undead who had passed through the walls. As a result, the white bone demon who slapped his thigh bones and jumped his feet used only a pile of garbage to make the dwarves completely let go of the road leading to the city wall, and this qiē was done willingly.

Seeing this, Robert's choice was very simple, that is, to take her husband away from the bone demon who was playing stupid again, and at the same time raise the danger level of the other party again. Robert felt that maybe he might be sold by the other party, and he might be very happy to count the money for the other party. And her husband is more likely to be sold, and after counting the money, he will happily run to let the other party sell twice. Ratamicius didn't care about Robert's wariness, because the only thing he cared about now was the dwarves' expressions when they saw their elite troops under the walls. Unfortunately, the distance was a little too far for Latamicius to read the faces of the defenders on the wall, otherwise he would have been happier.

In fact, at this moment, Chen Kai had already seen that the situation was wrong, and at the same time, there were several dwarven guards who were not right, and they all saw Chen Kai pick up the bones that had fallen from the ground, and then gently pinched them. The bones, which should have been very strong, were directly crushed, and they were as fragile as flour. In this case, the dwarves don't think it's because of the strength of Chen Kai's hands. No matter how strong the force is, it is impossible to crush the skull directly like kneading dough, or with your fingers. The only possibility is that the bones are rotten or fragile enough to crumble when pinched, and the bones they collected confirm this. When the dust cleared, all the dwarves knew that they had fallen for the undead. Exchanged the powerful explosives for a bunch of miscellaneous soldiers, and most importantly, cleared the road in front of himself and the enemy because of this explosion. (To be continued.)
