Time passed quickly in the repeated cycle of constantly defeating the bone creatures, and then waiting for the arrival of the bone creatures and then defeating them again, and there were still two hours left before the end of the mission, and the canopy was also under this continuous defeat, and the last layer of the canopy was already full of cracks, and it was also not long to bear.

Especially now, the white bone creatures that appear are generally extremely strong, and his roaring skill needs to be used a dozen times in a row to be able to get it done.

This has also directly led to a sharp increase in the current indifferent mental consumption, and if it weren't for Ophelia and Kunpeng's mother and daughter sharing and controlling part of his mirror image, he wouldn't be able to survive now.

However, it is now almost at its limit.

"The canopy can still support for a maximum of an hour, and if the strength of these subsequent creatures increases again, then it will only be half an hour at most."

Looking up at the canopy barrier that was already full of cracks, he took a deep breath of indifference and temporarily suppressed the stinging pain in his head, and then tiredly pressed against his eyebrows and opened his mouth to groan softly, and the content of the words was also transmitted to the ears of Ophelia and Kunpeng mother and daughter in the other three directions through the mirror image, so that the expressions on the faces of the three people who heard the words deepened again.

Now all of their mental power has been seriously overdrawn, and the indifference as the main output is even more of an overdraft in the overdraft, and they can already feel it from the mirror, but this time is still the most critical juncture, there are only ten or two minutes left, and they can endure it forcibly, but there are still two hours! It's not 20 minutes, it's 20 minutes! Even if the canopy was still four floors full, they probably wouldn't be able to hold out until that time.

"Are there no remnants of dragons in this dragon city? Even a bone dragon can do it, at least, some people! “

After shaking her head to put aside the tingling pain in her mind and refresh her mind a little, Ophelia looked down at the bones that had been scattered all over the ground because of the white bone creature that had been killed before, and said softly in a somewhat tired tone.

Now if there is no foreign aid, they will not be able to hold this place at all, once this place collapses, then their previous efforts will all be in vain, this is still secondary, and more importantly, once lost, then the dragon heart in the city will also be destroyed by these white bone creatures, and then their purpose will be completely nullified.

"They're coming!"

Not long after the words fell, the indifferent mirror opened his mouth by indifferently sharing information, making the former who heard the words, the Kunpeng mother and daughter not far away, and the indifferent ontology all take a deep breath again.

Cheering up, the four of them attacked.

It's just that this time, compared to the initial backhand counterattack, whether it is reflexes, control and skill cohesion, they are much weaker, plus these white bone creatures at this stage already have a fairly high damage immunity, almost instantly, a group of white bone creatures climbed on the periphery of the canopy, and in an instant, the crack on the canopy was deepened by several points, and the crackling sound from above could be faintly heard.

This is a precursor to the collapse of the canopy.

"Ding, the current city defense time has exceeded four hours, and with the current number of all players, the difficulty of the task has increased! The remaining time drops to the last hour, and the rewards increase! Get help defending the city! ”

Finally freed up some time for all the white bone creatures to be solved, and the sound of the system prompt suddenly sounded without warning at this time, and at the same time, the remains of the white bone creatures they had solved before began to change.

"Difficulty!"

For the scene of the change in the wreckage on the ground, he didn't care about it or pay attention to it, he was more concerned now, no, what he cared about the most was that the difficulty increased!

It's been a time like this, and it's actually more difficult!

Although the mission time is directly shortened by one hour, and the god has modified the last hour, it will be quite difficult to defend the city in this last hour!

Originally, this task was already at the reincarnation level, but now the difficulty has increased again, which is already a disguised announcement of the end of the task!

On the other hand, Ophelia and Kunpeng mother and daughter not far away, who didn't hear the system's prompt, focused on the wreckage on the ground at the moment, where the previous wreckage had begun to condense into bone dragons!

Helper! After four hours of deadly defense! The helper is finally here!

"Prepare, the difficulty of the mission has increased!"

Before they could be happy for a moment, a reminder from indifference sounded, and the content of the words directly made the three of them startled.

As I thought before I was indifferent, at this time, the difficulty has actually increased!

Before they could speak, another round of white bone creatures arrived, and there were not many of them, only four of them, but the size of these four was unusually large, and they could see each other from afar, and the speed of the other party was unexpectedly slow.

However, the expressions on the faces of the indifferent people who saw the appearance of these four creatures changed suddenly.

This wave, no, the follow-up white bone creatures have completely disappeared, only the last four remain, coupled with the huge size and slow speed, indifference can already think of how perverted the attack ability of these four white bone creatures is.

"Can't let them come close!"

Taking a deep breath, Indifference took the lead in rushing out, rushing towards the huge white bone creature in his direction, and in the middle of the way, the offensive skill directly exploded.

At the same time, Ophelia and the others also quickly came back to their senses, and as indifferent, they quickly rushed towards the white bone creature that was opposite the door, and the offensive skills in their hands were all launched without hesitation.

Countless skills fell on the heads of the four white bone creature giants in the blink of an eye, however, the damage that was fed back did not reduce their health bar in the slightest, or rather, reduced a little, but the value was a little low, and the roaring damage on the indifferent side simply only hit a fixed 0.000% damage! That's right, it's 0.000 percentage damage!

Seeing the four-digit percentage damage after the decimal point, he indifferently and decisively gave up the roaring skill, and directly approached the other party at close range, initiating a close-range physical skill.

Due to the difference in size and speed, the white bone giant had no way to attack Indifference, and after a few random counterattacks and found that there was no way to attack, the other party simply ignored Indifference and continued to walk slowly towards the center of the ancient city.

As for indifference, after seeing that the other party directly ignored his attack and continued to move forward, the attack in his hand became even more wanton, maybe the damage is not as high as other skills, but physical skills don't need mental power! This is the best news for him now!
