The howling wind from the smashed window, as well as Lu Chengfeng's warning, made Chen Liu immediately aware of the danger.

His reaction was also extremely fast, and he instantly drew his sword, turned around, and released a dazzling light from his condensing energy. Taking advantage of the rushing monster's subconscious closing of his eyes, he swung out a sword qi, blocking it slightly, and at the same time rolled out three meters sideways, just enough to let its collision miss. Under the action of huge inertia, the monster slid for more than twenty meters before it regained its shape.

Just as it shook its head vigorously and was about to attack again, Lu Chengfeng and a few people had already surrounded it.

It was a pterodactyl monster bird that was more than four meters long and had blue scales on its body. Compared with the real dragon, its size and strength are much worse, but the shape is very similar, so it is called a pterosaur bird. At this moment, affected by yesterday's magic fluctuations and the aura of Sky City, its yellow pupils were full of bloodshots, and it looked full of attacks**. The strength has also risen from the ordinary sixth-order to the sixth-order high level!

Finding that it was surrounded by several powerful enemies, it not only did not fear, but roared more impulsively, flapped its wings and swept towards Chen Liu again, probably thinking that it was easy to bully.

This kind of contempt suddenly made Chen Liu angry.

Although in fact his strength is indeed the weakest, being underestimated by a monster still makes Chen Liu very unhappy. Facing the pterodactyl monster bird rushing towards him, he condensed his fighting spirit to the extreme, and the Saint Blessing Long Sword in his hand was pointed out one after another, laying a continuous sword net in front of him.

If he faced the Pterodactyl Monster Bird alone, Chen Liu would definitely not be so impulsive, after all, there was a whole rank of strength gap. But now, he knew that several masters around him would not let this guy hurt him, so he was relieved and boldly chose to face him head-on.

However, Chen Liu found that he was thinking too much.

Of the five people around, except for Liu Wendao, who was a mage with very poor talents, any of the others were genius-level masters. Seeing the blue pterosaur monster bird attacking again, the flame element on Liu Yuhan's body rose up, and with a wave of his staff, he put down the flame impact in front of Chen Liu's body and on the path that the pterosaur monster bird must pass. The moment the pterosaur flew over the sky, blazing flames surged from beneath its body, tossing it hard.

The ultra-high temperature of the roasting made the pterosaur monster bird let out a painful roar.

However, before it could fall from the clouds, Liu Yubing also swung the cryolite staff and fired a round of ice spears at it. This was Liu Yubing's most proficient and skillful attack magic, and after she stepped into the fifth order, it was incredibly powerful. More than a dozen ice spears flashing with deadly cold qi shot out continuously in less than three seconds, and almost every one of them inserted a blood hole in the body of the pterosaur monster bird!

From extreme heat to extreme cold, the huge temperature change made the wound of the pterosaur monster bird worsen dramatically.

At the same time, Zu Liang pushed with both hands, and the white cone-shaped telekinetic cannon also shot out. At a distance of ten meters, he was instantly overtaken by the super-fast Nian Qi. It was enough to crush the power of ordinary Douqi armor in one fell swoop, and blast the scarred pterosaur monster bird out, not only splashing large pieces of blood and scales, but half of the wings disappeared directly.

In the end, Lu Chengfeng, who accelerated to catch up, jumped to its side, and waved the lightsaber in his hand high.

Accompanied by a blurry and dazzling light, the Great Evil Light Slash, one of the three major killing moves, was launched, and two intersecting sword qi shot in from its biggest wound, completely shattering its body into pieces!

The tacit understanding of the four elite masters joined forces and instantly ended this sixth-order high-level pterosaur monster bird.

From Liu Yuhan's prediction to fly, to Liu Yubing and Zu Liang's ferocious attack, to Lu Chengfeng's final blow, this pterosaur monster bird did not resist at all except wailing. Even, the sword net that Chen Liu laid in front of him completely failed, and it failed to have any effect.

"It's too fast......"

Ryu Wenwen was going to spend two seconds chanting a thunderstorm, but before the magic was completed, the pterodactyl monster bird had already been beaten to ashes, and had to frustratedly shift the target and shoot at the clearing. Although he knew that the guests brought by the two little princesses of his family were extraordinary, he never expected that they would be so strong!

A sixth-order high-level monster was easily killed, it was like killing a chicken.

"The afterlife is terrifying. ”

He sighed, looked at the half-burnt, half-frozen mutilated corpse, shook his head, and continued to set off with a few people.

From the moment he encountered this blue pterosaur monster bird, the rest of the journey began to become unpeaceful. In less than half an hour, they encountered four pterosaur monster birds one after another. In addition to the three of them, which are all blue, there is also one that is more special, and the scales on the body surface are white. This white pterosaur bird, although slightly less powerful than the blue one, is faster and more resistant to magical damage.

However, it is still only a united enemy.

In front of the six people whose strength was beyond imagination, these pterosaur monster birds had no exception at all, and they all fell to the ground in one round, failing to bring them the slightest decent threat.

This situation went all the way to the twentieth floor.

According to the Mage Guild, from this level onwards, it can be regarded as the true scope of the Dragonman's Tower. Prior to this, the pterodactyl monster birds had only occasionally run down from above. In fact, it was precisely because of this that the number of monsters they encountered suddenly increased as they ascended the folding stone staircase to the twentieth floor.

The great changes in the sky city caused by the fluctuation of magic power yesterday also entered the hardest hit area from this layer.

Bypassing the tic-tac-toe corridor in front of them, the six men searched cautiously. Because from this level, it is very likely that you will encounter Gu Lan who is trapped in the Sky City. It's just that they had only explored two sections before the Sky City pane at the end of the corridor was knocked open one after another. In the shock of the six people, four or five blue pterosaur monster birds flapped their wings and flew in, looking unkind!

However, that's not all.

Behind them, through the wide open windows, seven or eight more of the same monsters came in one after another. Seeing six prey appear in front of them, they let out a low cry from time to time, which makes people sound hairy. The golden-winged thunder eagle on Lu Chengfeng's shoulder flapped his wings even more uneasily. Although its rank is much higher than these pterosaur monster birds, it is only in its juvenile stage now, and its strength is not even a second order, and in the face of so many enemies, it naturally has a strong fear.

Affected by the magical aura of mutation, these pterosaur monster birds are extremely aggressive**, trying to surround the six people.

When I encountered these strange birds before, there were only one or two at most. Now it has suddenly become more than a dozen, which makes the six people feel pressure. You know, these are all monsters with sixth-order high-level combat power. If you are surrounded by them, even if the strength of the six people present is good, you will have to go through a hard battle!

"Back off, back off!"

If you are surrounded by them, it will be very difficult to fight. Lu Chengfeng recalled the corner of the corridor just now, and immediately greeted loudly. If they can retreat to the position just now, with walls on three sides, they can match the echelon firepower, and only need to defend one side, and the pressure is greatly reduced.

The people who came with him were all smart people, and almost instantly, several of them turned around and hurried back.

The flight speed of the pterosaur monster bird is very fast, but in the tic-tac-toe corridor of this sky city, it will be affected after all. What's more, Lu Chengfeng also gathered momentum to unleash an ice blade fluctuation sword, freezing several of the fastest chasing pterosaur monster birds, slightly slowing down their pursuit speed. By the time the monsters swarmed up to catch up, the six had quickly retreated to the end of a cloister.

Behind here is a dead end, with walls on the left and right, and there is only one way to come.

If you don't block their attacks, you'll be trapped here, but this probably doesn't exist for the six.

"Ice Pact - Ice Elf!"

"Flame Pact - Flame Demon!"

As mages who need to focus on protection, the Liu family sisters' standing position is naturally in the innermost. The moment they completed their formation, the sisters raised their staffs at the same time, summoning elemental creatures that could help. The next moment, two ice spirits the size of a basin and a sturdy flame demon walked out of the summoning circle, consciously blocking the front.

In such a short period of time, the pterodactyl monster birds swarmed up, staring at them fiercely, ready to attack at any moment.

Seeing their dense position, another mage, Liu Wenwen's eyes lit up, and he summoned a thunderstorm with all his strength.

This fifth-order lightning group attack spell has good damage, but it needs a long time of guidance. At present, it can be very effective when there are people to protect and the terrain is relatively narrow.

At the same time, Lu Chengfeng and Zu Liang, who were in charge of the break, also stood at the front.

Zu Liang, who has the three major fighting skills of Thunder Clone, Nian Qi Surrounding, and Nian Qi Cover, has the top defensive ability among the six, so he naturally has to be on the front line. As for Lu Chengfeng, although he didn't have a Douqi armor yet, the inheritance-level battle armor on his body could almost perfectly make up for this, allowing him to also block the front.

Chen Liu, who was the weakest, was a little later in the two, cooperating with the Flame Demon and the Ice Elf, preparing to do the second round of output. Probably stimulated by the thunderstorm brewing in Liu Wendong, the two pterosaur monster birds, which looked a little uneasy, flapped their wings and pounced first. Due to the distance, Lu Chengfeng could even see their incomparably sharp long beaks, as well as their claws that shone with cold light. There's nothing to say in this case, just do it. Lu Chengfeng urged the Infinite Frost Dou Qi, and at the same time mobilized the blood qi, condensing a blood-colored cross in front of him. The blood-marked cross sword, which took shape almost instantly, collided with two oncoming wing-dragon monster birds, causing a violent explosion. Seeing that there was an opportunity, the two ice elves spit out ice spikes from afar to attack. Liu Wendong's thunderstorm fell even more violently. One after another, the arc jumps raged, and the hard-hit pterosaur monster bird screamed again and again!
