Boom boom boom boom! Amid the rumble of cannons, a large burst of fire exploded over the Undercity. After the artillery collided with the high tower defense cover, a strong impact was generated, forming a wave of flame frenzy. At the same time, the counterattack from the Undercity officially began. Compared with the artillery attack of the tri-families, the attack of Tallinn is obviously more in line with the characteristics of this era. The spires of the tall towers shone with the brilliance of thunder and lightning, dragged a long electric chain across the air, and landed on the coalition positions, which was also a flash of electric light. All armies raised their shields to resist, and the Tyrant raised their battle shields. Their shields carried a strong blood light to resist attacks. They were the Tyrant Blood Shield fighters; the Feathers jointly released the arcane magic of guardian light. , Forming a huge guarded airspace, all attacks entering this area will be reduced layer by layer; Wujizong also uses a joint array to resist attacks outside. I saw the arcs scurrying around outside the shield like silver snakes, bringing large silver-white flashes on the battlefield. At the beginning of the battle, both sides were offensive and defensive, with great momentum, and casualties were never seen. However, as time passed, the defensive shield gradually ruptured, and casualties began to appear. Some low-rise towers could not withstand the attack at first. Under the bombardment of fierce artillery fire, the defensive cover disappeared, and the tower body directly suffered the bombardment. Despite its efforts to repeatedly release powerful thunder and lightning, it appears to be so fragile in the face of tens of thousands of attacks that it was overthrown in an instant. However, the spirit race in the tower escaped in time and entered the empty tower behind to stand by. The spirit race lost the Arcane Tower, and the coalition lost a real life. The continuous bombardment of thunder fell over the coalition forces. Some unlucky blood shield guards were placed in the most violent area. They only consumed the energy of the blood shield in an instant. Before they had time to react, they were shattered into dust by the violent lightning. The same situation also occurs in the feather and human races. The chaotic energy frenzy is unevenly distributed everywhere, so that the pressure on all parties is also different. There are always areas where the defense is broken in advance because of the heavy attack. loss. Whether it’s a tunnel block or a dark ambush, it’s a small-scale area battle after all. Only a battle like this is the real big scene. In just a very short time, the death caused to the point where everyone is heartbroken. . "These arcane towers are too powerful." Gutian snorted softly and turned to look at Su Chen: "There are many tall forests, and the defenses are tight. The spiritual family has a deep heritage. If such a confrontation continues, I am afraid that the spiritual family's Tallinn will not At the end of the day, the soldiers of our clan are all dead." Su Chen responded: "Although Tallinn is strong, it cannot move. It is not appropriate to fight them in positional warfare. The order spreads out and allows everyone to take turns to resist the attack. Once the defensive cover is broken, Immediately retreat, and protect from the rear. Take turns to rest and attack.” As the order was passed quickly, the coalition began to change its strategy. Instead of forcibly confronting the spirits, it adopted a rotation strategy, only at the border of the Tallinn attack. Confronted and constantly exchanged. To put it bluntly, it is to fight with a soft knife. The new tactics greatly reduce the casualty rate, but the attack speed will be greatly reduced, and the resource consumption will double. But as long as too many casualties can be avoided, all this is worth it. As a result, the war has entered a tedious and long rhythm, and no one has the will to attack each other, just constant bombardment. Light and flames filled the vast underground space of Undercity, turning it into a land of thunder and fire. Although Tallinn is strong, it is impossible to move after all. Su Chen seized the weakness and continued to rotate attacks, his own casualties were greatly reduced, but Tallinn fell one by one. Perhaps it was that something was wrong, and finally there was a change in the spirit race. A black flame suddenly rose from the Undercity. The flame condensed into a huge black figure, turning into a black flame monster; then there appeared a tall bronze puppet wrapped in an electric arc, holding a huge sword and a shield; another giant tree swayed, and its whiskers swayed and fell out Countless cyan fruits, but from the fruits popped out a cyan dwarf, ferocious and ferocious; there was also a black shadow, moving on the ground, without any real existence, but exuding a huge weirdness. As soon as these four strange existences appeared, an astonishing energy burst out in the Undercity, and at the same time it rushed out. Under this brilliant energy, the three-ethnic coalition forces went silent at the same time. While they misfired, the four huge monsters had already attacked and rushed directly to the coalition camp. "Sure enough, do you still have to take the initiative?" Su Chen was not surprised. Passive defense has only a dead end, and any successful defense must have the power to counterattack. Otherwise, as before, sooner or later it will be consumed. Only by attacking can the opponent's rhythm be disrupted. These four monsters should be the secret weapons cultivated by the spirit race for many years. As a race, especially a race that loves research, some backgrounds are normal. At this moment, the four monsters came out at the same time, and Su Chen raised his brows: "Qingluo, you go and deal with the Black Flame monster. Li Chongshan, you deal with the tree beard. My Wujizong took two, and as for the other two, I will leave it to the two. "He smiled and said to Gu Tianyue and Danba. Danba has said: "The sword and shield guard belongs to me, Longzel, you go and deal with it." Longzel has shouted and rushed out to meet the golden sword and shield guard. Gu Tian frowned, he actually wanted to deal with the sword and shield guard even more, the shadow was too secretive, and secretiveness often meant unpredictable and difficult to deal with. But Danba was fast and grabbed the sword and shield guard. He was too embarrassed to say you let me. He had to say to a Yuzu warrior next to him: "Go and stop it." Seeing that Yuzu warrior went out, Su Shen sighed: "I'm afraid it's not enough." Gu Tianyue hummed: "Qingfu is a nine-ring arcanist." "That's not enough," Su Chen replied. "Huh?" Gu Tian hesitated. Seeing that the Yu clan warlord named Qingfu had flown past, a crisscrossed flame of light fell on the black shadow. It's just that the black shadow moved on without feeling at all. Wherever he went, he saw the feather clan soldiers ulcerated and died. Qing Fu was shocked and shot continuously, but no matter how sharp he shot, he couldn't stop the moving shadow. The shadow twisted forward, swallowing all the existence that entered its envelope. Qingfu was horrified, and had to retreat and attack, constantly changing his attack methods. Su Chen was also watching. Suddenly he frowned: "Be careful!" Brush! Guanghua flashed, and a blood line suddenly appeared on Qing Fu's forehead. He froze first, then split into two halves. This nine-ring arcane master, unexpectedly died like this. A ruowuruowu black figure quietly left. "I found you!" Su Chen's eyes condensed, and he grabbed the void, and the black shadow was immediately blocked and unable to move. The more Danba and Gu Tian looked at them at the same time, they were shocked. In order to better observe the battle pet, the three leaders are all in the back, and there is still a long distance from the front. But Su Chen was able to directly grasp the target at such a long distance. This spatial method was really surprising. Looking at the distance again, after being controlled by Su Chen's remote control, the twisting black shadow continued to twist, revealing a little brilliance, but the black shadow stopped moving. Danba has already realized: "It turns out that this is its main body, and the dark shadow is just its blindfold." "It should be the product of the Spirit Race's research on some concealment method, but it is a failed product... a powerful failure product." Su Chen road. "You mean, these four monsters are all failures?" Gu Tianyue was shocked. The Black Flame Giant was facing Gu Qingluo, the tree beard was facing Li Chongshan, and Long Zeer was fighting the Golden Sword and Shield. Each of them was so powerful, but Su Chen called them a failure. "Yes, a failed product." Su Chen said with certainty: "Black Flame is a study of flame energy, hoping to find a way to enhance the resistance of flame elements; Tree whiskers should be an attempt to create a new type of unit. Cannon fodder soldiers can be produced continuously. After all, the population is the eternal flaw of the spirit race; the golden shield guards the spirit race's expectations for the improvement of the frontal battlefield. If it can succeed, the spirit race will no longer be a race that is unable to fight on the frontal battlefield. " Indeed, if these monsters can be mass-produced, this is definitely not the case. Therefore, these monsters must be failed products, with various unknown defects. For example... The Golden Shield Guard suddenly released strong light and heat from his body when he hit it. Danba realized that it was not good, and shouted: "Longzel, go back!" Longzel always followed Danba's orders first and then thought, and he quickly retreated. As he retreated, he saw that the golden shield guard had burst like a sun, and a large amount of light overflowed from his body, instantly permeating the audience, setting off a wave of light strikes. When the halo dissipated, the Golden Shield Guard had disappeared. Also disappearing were a large number of coalition soldiers around it. Longzel was also lying on the ground with blood and blood, not knowing whether it was alive or dead. Sure enough, it is a monster that can't fight for a long time, and it will even explode. Fortunately, the opponents who fought with Gu Qingluo and Li Chongshan didn't have the ability to explode, but the black flame giant slapped and hit, suddenly splitting into tens of millions, and smashing downward like a rain of meteors. It was not a self-destruction, but the damage was equally terrifying. Fortunately, Gu Qingluo was prepared and prevented most of the attacks in time. Li Chongshan was the most relaxed-the whiskers became smaller and smaller, and as it continued to spawn dwarf soldiers, it eventually shrank into a small sapling. Li Chongshan put it away. Although this thing is a failed product, it seems that it still has the value of continuing to study and use it. Unlike the other two, there is no bones left. As for the dark shadow controlled by Su Chen, it was also dead. Yes, after unable to break free of Su Chen, the dark shadow twisted a few times before disappearing completely. Su Chen could feel that its life energy disappeared directly, just like its nature of existence, saying that there would be no if there was no, and I don't know how to die. It was really weird. The four monsters once again brought some damage to the coalition forces, and also caused some headaches for everyone. "I don't know how many failed products like this one have." Gu Tianyue said. "There should be a lot more." Su Chen Youyou replied. Gu Tian glared more and more: "Don't crow's mouth." Su Chen said: "Although you don't like it, this is the truth. The Spirit Race has conducted countless researches for thousands of years. If you want to say just this, I absolutely don't believe it. Yes. If you don't believe me, wait and see." As Su Chen's words fell, a large group of monsters rushed out of the Dark City. This time there are more, and there are all kinds of them.
