Su Yu and the others fought and retreated, and soon arrived at the eleventh floor, Su Yu destroyed the stairs on this floor with his own hands, and watched the monster that stepped on the stairs fall down again.

The army of monsters in the rear also slowly advanced in as a whole as everyone fled, and the monsters that the three boss monsters had just summoned were destroyed, and they were reminded again, and the water dragon, the cyan python, and the reinforced concrete giant were summoned again.

Now that Ah Da and Wu Tian's fifth-class creatures are all in the fifth stage of growth, the combined attack skill can only be used five times a day, just now they have each used it once, and each has four times left, Su Yu watched the three terrifying monsters pounce again, but he didn't want to use the combined attack skill casually.

Until the moment of crisis, he would never want to use this precious opportunity to combine attacks casually.

Su Yu showed a thunderbolt spear in his right hand and threw it towards the reinforced concrete giant from a distance.

With a "snort", the reinforced concrete giant roared, this thunder and lightning spear had little effect on it, Qin Jiagui had already activated the "metamorphosis evolution" ability, the jet-black metal gradient red all over his body, and the cannonballs on his shoulders dragged the tail of the fire, constantly shooting at the reinforced concrete giant.

"Boom", "boom", "boom" The sound of the big explosion was endless, compared to the thunderbolt spear, the lethality of this double-shouldered cannonball to the reinforced concrete giant was greater, and the reinforced concrete on its body was constantly splashed, and the cement giant's body shook, greatly slowing down the speed of its pounce.

With the passage of time, there are more and more seventh-level monsters among the monsters that appear, and the number of seventh-level elites among its seventh-level monsters has also been greatly enhanced, and several seventh-order powerhouses after the break suddenly all felt the pressure doubled, and the energy of the native beast with the surname of the earth fused in Zhang Zhongmou's body has been used up, and he can no longer use the "Ground Thorn Assault" skill without restrictions, so he can only use the "Rock Crushing Fist" with the "Rock Cannon Head Hammer" in person, and constantly face this group of seventh-level elite monsters that pounce on him in close quarters.

At this moment, for the sake of others, Zhang Zhongmou and a few people can't move their positions arbitrarily, otherwise they may release a seventh-order elite monster, this kind of seventh-order elite monster rushed into the crowd in the rear, which is almost a terrible consequence of killing with one blow, which forced Zhang Zhongmou and a few people to stick to their positions and fight hard, the difficulty of this battle has greatly increased, even Zhang Zhongmou, who has reached the peak of the seventh order, gradually feels extremely difficult.

Among all of them, maybe only Su Yu can still support it, his whole body, has gradually bloomed blue and white lightning, one after another lightning converged behind him, forming the lightning lizard tail, facing the oncoming monster, the lightning tail continued to slap out.

Each blow will destroy a monster, facing the impact of this monster tide, Su Yu almost bears most of the pressure, otherwise everyone's team would have already been scattered.

Everyone moved up and retreated one by one, and when they retreated to the fifteenth floor above, suddenly there was a "crackling" sound above, followed by the collapse of a large number of cement walls, and immediately after, one by one seventh-level elite monsters emerged above.

Eventually, these monsters no longer simply attacked from below, but climbed down the wall to the top, and then formed a flanking attack on the servants from the top of the building.

This time, everyone's color changed, Wu Tian immediately summoned the combined attack skill again, and suddenly, the miserable green flames swallowed the sky, burning the group of monsters that had just emerged from above, and at the same time shouted at Su Yu: "I can't hold it here, let's escape-"

Su Yu looked at the buildings below that were full of monsters, and then looked at the monsters above that appeared endlessly, nodded slightly, and shouted: "Ada-" Ada-" Ada--" Ada-

At the same moment, with a wave of both hands, thousands of thunderbolts were released wildly, and the sound of "crackling" was endless, and thunder and lightning were bombarded wildly everywhere, and the monsters at one end howled and were hit by the thunderbolts, and then turned over and planted down, and Su Yu, Li Dong, Yuan Niping, Lei Rui and others had already climbed on Ada's back.

"Howl-" The reinforced concrete giant appeared, put his arms together, and slammed down, smashing down on the group of people who had just sat on Ada's back, and there was no wave.

Everyone was shocked, Su Yu kicked his feet, and the black-scaled lizard beast dragging the blue and white lightning instantly rushed and jumped, and with a roar, the golden claw of Su Yu's right hand appeared, and he waved down heavily at this pair of giant arms.

There was a loud bang, and immediately, the two reinforced concrete giant arms shattered and exploded, and the lizard claws mutated by Su Yu's feet kicked heavily in the chest of the reinforced concrete giant.

The five-meter-tall giant roared and shook "boom" and fell down, falling out of the cement and stone all over the ground.

"Quick-" Su Yu landed, roared again, and then shot out, bombarding the outer wall of the building.

The "lizard arm" shook hard, and immediately, the reinforced concrete mixed with bricks shattered and exploded outward, and Qin Jiagui launched cannonballs in succession, bombarding this crack, making the gap in the outer wall of the fifteenth floor bigger and bigger.

The monsters below surged, and they seemed to know what they wanted to do, and at this moment they were frantically attacking up and down, and Wu Tian was also busy making his fifth-class creatures huge, and everyone climbed on the backs of these two fifth-class creatures, Zhang Zhongmou, Su Yu, Wu Tian and others broke off.

"Black Flame Hell-" Su Yu roared, almost and Wu Tian launched the combined attack skill again, the two combined attack skills were launched at the same time, the flames swallowed the sky, enveloping the entire fifteenth layer, and in the flames of this combined attack, Su Yu, Wu Tian and Zhang Zhongmou and others finally boarded the back of Ada, the first fifth-class creature, with a long roar, the gap in the outer wall was big enough, and the two fifth-class creatures, carrying everyone, glided down one after the other, falling from a height of dozens of meters.

At this moment, the whole world was in a scuffle, a large number of monsters launched an impact on the buildings, and the monsters left on the avenue outside became scarce, Ada, and another fifth-class creature carried everyone, gliding from a height of dozens of meters and falling heavily, everyone snorted, the impact was still very powerful, and Su Yu had already jumped out with both feet.

Around the avenue, the monsters that were still outside were shaken, and immediately looked here, and then pounced.

"Chong-" Su Yu knew that he must not stay outside for long, otherwise he would attract countless monsters, then, everything was over, and he could only take advantage of the fact that all the monsters had not reacted yet, and rushed to the tall building they chose as fast as possible.

Ada, and the other fifth-order creature did not shrink, but carried everyone and rushed behind Su Yu frantically, their speed was even faster than that of ordinary seventh-order powerhouses.

The black-scaled lizard that Su Yu incarnated incarnated incarnate with thunder and lightning all over his body had turned into golden yellow, obviously, he also fought with all his strength, and the terrifying burst force made every step he took cracked and the concrete floor cracked and fell into a lizard's paw-shaped pit. The shattered cement debris splashed everywhere, Su Yu flew vertically, and thousands of thunderbolts slashed out in all directions, he rode a thousand, and actually opened the way for two fifth-class creatures, one after another, monsters, whether they were level six or seven, or elite monsters, all of them were vulnerable, and they were all rolled and fell out by him one after another, and the effect of falling to the ground was broken bones and rotten flesh.

At this moment, Su Yu has exerted his strength to the limit, just like a super heavy tank, rushing out, invincible, and no one can stop him.

At a distance of 100 meters, they arrived in an instant, and the monsters on the surrounding avenues basically didn't have time to react, so Su Yu rushed into this building with two fifth-class creatures full of people.

This building is also full of monster corpses, a scuffle, is unfolding between its third and fourth floors, just like Su Yu observed, the number of human powerhouses gathered in this building is extremely numerous, at least more than forty people, at this moment is fighting with the monster army terrifyingly, these dozens of people joined forces, it is enough to shake the monster attack without falling behind.

Behind, Su Yu and more than 20 other people suddenly rushed in, causing the monster army to stir, Su Yu let out a long roar, kicked his feet, and rose into the air, and instantly fell into the monster group, and the golden claw in his right hand waved.

With a "porphyry", a seventh-level boss-level monster with a pattern that was being supported by a horde of monsters instantly had its head cut off by a golden claw, and he died immediately.

The strength of the monsters in this building is similar to that of the one who attacked Su Yu and the others at that time, and there are also three leader-level monsters, but at this moment, there is already a leader-level monster who has died, and with Su Yu's sudden appearance, he took advantage of his unpreparedness and solved another one, and the remaining last leader-level monster was also a little flustered, and then Zhang Zhongmou also rushed in like Su Yu, but he was attacked by seven or eight seventh-level elite beasts, and immediately, he fell out with a muffled snort, and blood was oozing out of the corner of his mouth.

Wu Tian landed, without saying a word, and once again launched a combined attack skill, a large number of miserable green flames swallowed the sky, and suddenly fifty or sixty monsters died tragically and were burned, dozens of people on the third or fourth floor saw that reinforcements arrived below, and immediately rushed down, and the monster army was suddenly overwhelmed.

Su Yu was no longer polite, and immediately launched the "Black Flame Hell" to burn wildly at the dense area of monsters.

Countless monsters died, a large number of monsters fled, and the fifth round of monster attacks came to an end.

Watching the monsters die or escape from the building, everyone didn't chase after them, just stood in place, gasping for breath, and had a feeling of being reborn as a human for the rest of their lives.
