After returning to the game, Mr. Zhang directly entered the difficult difficulty dungeon, as it was said on the Internet, the difficult difficulty is indeed a lot more difficult, but for Mr. Zhang, it didn't take much effort to successfully clear the difficult difficulty dungeon.

Having said that, this difficult difficulty dungeon is really time-consuming, even at Old Man Zhang's speed, it took a full 30 minutes to brush the dungeon to clear the level. It is said that it will take almost an hour for normal players to complete the level.

Next is the extremely difficult dungeon, and this time, Old Man Zhang finally felt a trace of pressure.

First of all, it is no longer possible to do a machine gun tower to fight the world.,Starting from the 25th wave.,Yuan Kou can kill the fence within 50 meters.,And the final BOSS.,It's all the defense towers with full output.,Kill under the fence.,Almost break the fence of the village.。

And then the extremely difficult fortress attack battle is similar, although the defense towers and zombie groups in front of it did not cause much trouble, but Old Man Zhang never dreamed that the final boss would be surprisingly laborious to brush.

Old Man Zhang wanted to hide his hand at first, but he didn't use Kangna, but he just relied on other heroic spirits to beat the boss, and as a result, he almost hid his hand and wiped out the whole army.

The extremely difficult BOSS already has a 70% damage reduction effect, which makes Zhang Qiuhan, who is known for his output, be greatly suppressed, obviously all attacks and skills can accurately smash on the opponent's body, causing extremely dazzling visual effects.

But this thing is good-looking, but the other party's health bar is missing.

In fact, this BOSS doesn't have much blood bar, it's just 100,000, and Mr. Zhang's millions of bosses have also been killed, but this BOSS is really too difficult to deal with, all kinds of attacks are tickling, and his attack, even if it touches the AOE damage casually, even if it is a purple heroic spirit, it will instantly disappear most of the blood value of half of the tube.

If it weren't for Old Man Zhang's operation being strong enough, and there were two super artificial intelligence to control the other Heroic Spirits, Old Man Zhang would probably have already killed more than half of the Heroic Spirits here.

But even if Old Man Zhang filled all the operations and fought to the back, he basically couldn't hold on.

No way, at this time, the players' eyes are focused on the terrible damage reduction of the boss, but they forget that this boss also has a terrifying instant death skill.

In the past, when he was on Normal difficulty, that instant death skill had lost Fafnir once in seconds, but this skill was just his last counterattack before he died.

But when it comes to extremely difficult difficulty, this skill is not a dying counterattack, but a skill will be thrown out from time to time, although the trigger probability of the instant death effect is only about 10%, which doesn't seem to be high, but this skill still has a must-hit effect, even if Zhang Qiuhan's dodge ability is outstanding, he can't avoid this skill.

However, the frequency of use of this skill is determined by the BOSS's blood loss, once the BOSS loses 3000 points of qi and blood value, he will immediately use a skill, and 100,000 points of blood will come down, which is a full 30 skills.

And this time Old Man Zhang's luck was not good, after 20 skills, three Heroic Spirits were summarily killed, so that Old Man Zhang was left with three Heroic Spirits, which was simply miserable.

If Mr. Zhang is a normal player with bonus points, it is better to say that he should have about 10 Heroic Spirits at this time, but the problem is that Mr. Zhang has given up the addition of cost point technology, and the number of Heroic Spirits is far from enough, and three Heroic Spirits are half of the Heroic Spirits that can participate in the battle.

In the end, there was no way, Old Man Zhang could only pull Connor out to fight.

As soon as Connor came out, the situation on the battlefield naturally changed instantly, and the powerful damage quickly killed the boss, but Old Man Zhang's brows furrowed even more.

Old Man Zhang originally thought that because Kangna's Thunder Prison skill was a real damage, it would be immune to the effect of avoiding injury. But Mr. Zhang forgot that the boss is immune to percentage damage.

Well, many Heroic Spirits have a percentage damage effect, and if such an effect is also effective on the boss, then no matter how much blood you have on the boss, you can kill it in a few minutes, which is unscientific.

Therefore, the percentage damage has no effect on boss units.

Of course, it's not completely ineffective, it's that this percentage of damage will be reduced by 90%, which means that it's only one-tenth of the original damage effect, but in this case, this amount of damage is completely insufficient.

Therefore, although the real damage is effective, the actual effect is even worse than the normal damage.

But fortunately, Connor's own abilities and attribute panels are strong enough, and it is a level 65 red epic, so as soon as Connor appeared, it didn't take much effort to kill this boss, and Mr. Zhang also successfully cleared the extremely difficult dungeon, and he could challenge the nightmare difficulty at the level of a professional player.

However, Old Man Zhang was not in a hurry to continue to challenge, because Old Man Zhang knew that even if he went to the nightmare difficulty, it would be impossible to brush this copy, and the difference in strength between the two sides was there.

"It's a pity that the level of most of the old man's heroic spirits is still too low, only more than 30 levels, this disadvantage is too great!" Old Man Zhang muttered.

But in fact, Old Man Zhang still has a hidden worry in his heart, that is, he feels that the increase in the difficulty of nightmares has reached an extremely terrifying level, even if his other heroic spirits have been upgraded to level 60, it is still impossible to pass the nightmare dungeon, unless Old Man Zhang can be promoted to level 50 or above, and at the same time has 10 heroic spirits above the orange level, he can consider the nightmare difficulty clearance.

Don't you see that all the pro players now are stuck in the nightmare difficulty and can't move?

This proves the horror of the nightmare difficulty from the side, this is a copy specially for powerful professional players!

"It seems that we will only talk about it when the old man is level 28!" Old Man Zhang glanced at his experience bar and the accumulated Yuankou, if he wants to rise to level 28, the fastest speed will have to wait until tomorrow.

As for why at level 28, you have the confidence to challenge the difficulty of nightmares, you can guess.

"By the way, it's extremely difficult to have a team mode copy, I don't know how far other people's copies have progressed, or the old man will go to team mode to see if he can rub a nightmare copy team!" Old Man Zhang squinted his eyes and pondered.

At this time, a white light suddenly flashed around Old Man Zhang's body!!

Don't get me wrong, it's not that Mr. Zhang has set off on some adventures again, but when the dungeon boss has been killed for more than 30 seconds, Mr. Zhang hasn't quit the dungeon, so he was forcibly teleported out of the dungeon by the system.

After the light ended, Old Man Zhang had already returned to his village, and just as his old man was about to contact the team of a strategy nightmare dungeon, a system prompt suddenly made our Old Man Zhang stunned.

"System: Congratulations to player Zhang Qiuhan, you have cleared the extremely difficult Hell Attack dungeon alone, the dungeon sweeping function is on, you can directly consume diamonds to sweep the dungeon!"

Wow rub ...... Quest Sweep feature!!!!
