"Poof. ”

Duan Lingfeng broke through, and in the battle, his cultivation strength broke through in advance, and with his breakthrough, his strength skyrocketed, and a powerful force filled his limbs and hundreds of remains. The Soul Breaking Knife in his hand swung violently, and only to hear a snort, the black-armored guard in front of him was blasted away.

The strength of the black armor guard skyrocketed, he was covered in steel and iron bones, invulnerable, and there was no blood flowing out of the slashed chest cavity. With such a heavy blow, even a martial artist at the peak of the Bone Refining Realm would be killed if he was so seriously injured, but this black-armored guard actually got up from the ground as if he was nothing, and waved the weapon in his hand to continue to kill Duan Ling Feng.

"Damn, it's not going to be so perverted, isn't this a Xiaoqiang who can't be killed. Wang Wei behind Duan Lingfeng saw this scene, and couldn't help but scold, if you don't play people like this, forget about invulnerability, this is simply a Xiao Qiang who can't be killed.

These are not people, these black-armored guards are a group of monsters, a group of monsters who have no pain and can't be killed.

A few people who were still lucky before, but now they are bent on evacuating this place. Staying is a dead end.

Wang Wei, Yu Ling, and He Laosi were retreating, and they did not disperse in a hurry, but retreated with Duan Lingfeng as the center. But their speed is greatly limited.

"The healing elixir, take it quickly, don't be reluctant, these monsters are too powerful, they can't be killed if they are so badly injured. Duan Lingfeng saw that Wang Wei and the others were covered in color, and he couldn't help but shout angrily.

"Young master, these monsters are too powerful and too fast, we can't resist them. Wang Wei cried with a sad face, they had already taken the healing Snow Ginseng Jade Dew Pill, but these mutated black armor guards couldn't kill them at all, and they had no choice.

If these black-armored guards mutated at the beginning, then there would be no need to fight this battle at all, these monsters would not be killed at all, and they would just be guilty of fighting, so they would just wipe their necks and forget it, such a battle would not have the slightest chance of winning.

"Everyone takes me as the center, Wang Wei, Yu Ling, after the two of you break off, Yuan Fang is in the center, I will open the way in front, retreat into the Lei Yuan Swamp first, and use the strange terrain of the Lei Yuan Swamp to kill these guys. "Duan Lingfeng and a few of them came out of the dangerous Thunder Yuan Swamp, although it was only the periphery of the Thunder Yuan Swamp, it was also very dangerous, and the Thunder Arc split down from all around without a single trajectory, which was just used to deal with these monsters.

Cang fought against Liao Chengyong alone, and he couldn't join them in a short time, Duan Lingfeng and they could only attract these mutated black armor guards. If they can kill these black-armored guards, then they can go to the rescue.

With Duan Lingfeng as a sharp knife, any black-armored guard who attacked them would be knocked away, although it could not completely kill them, but it could stop their progress.

Duan Lingfeng firmly believed that these black armor guards were not really invulnerable and could not be killed, but they had not yet found the vital point of these black armor guards, as long as they found the vital weakness of this black armor guard, they could easily kill them.

"Ding, congratulations to the host for successfully performing the Soul Breaking Knife Technique, proficiency +10. ”

"Ding, congratulations to the host for successfully killing the enemy with a critical hit, and getting a reward of 400 experience points. ”

......

Duan Lingfeng killed the enemy in front of him to open the way, he used the Soul Breaking Knife Technique, and all that increased was the proficiency of the Soul Breaking Knife Technique, and suddenly, a black-armored guard in front of him was shot in the head by Duan Ling Feng, and an alternative system prompt sounded in his mind.

"Crit. A strange look appeared in Duan Lingfeng's mind, these black-armored guards had been mutated by corpse beetles, and they had become invulnerable, and ordinary vital points could not be killed at all, even if they were fatally wounded, they would not say a word, and continued to rush forward without fear of death. But just as Duan Lingfeng was using the Soul Breaking Sword Technique, a sword aura directly exploded the head of the black armor guard.

In the past, Duan Lingfeng was a ten-fold forging body, and he had one hundred experience points for skipping the level to kill the enemy, but now when he used a critical attack to skip the level to kill the enemy, he actually obtained four hundred experience points, and this experience point reward was actually tripled. Reach four hundred, kill one now and kill two before.

"Their weakness is their heads, and just popping their heads can kill them. Duan Lingfeng shouted at Wang Wei and the others, the weakness of these black-armored guards must be their heads. They didn't know exactly where their heads were, but as long as they blew their heads, he didn't believe they couldn't be killed.

"Haha...... Young master, you are really a wise and martial artist, the weakness of this black armor guard is really in the head, the position of the center of the eyebrows, as long as it hits his eyebrows, this black armor guard will be useless. Wang Wei was reminded by Duan Lingfeng, and he stabbed out, hitting the enemy's eyebrows, and the black-armored guard fell to the ground and twitched a few times before he got up.

"I really thought that these black guards didn't have any flaws, it turned out to be the eyebrows, and everyone attacked their eyebrows for me. Yu Ling and the others shouted, they attacked the head of the black armor guard, and in an instant, the pursuing black armor guard was reduced by several people, and the pressure on the five people was greatly reduced.

"Critical hits, how can you cast critical hits? After finding out the weakness of this black armor guard, Duan Ling Feng found that he hit the black armor guard's eyebrows and killed the enemy, he only gained two hundred experience points, this is still a skipping kill, if it is not a skipping kill, he can only gain a hundred experience points at most, this is still the reason why the strength of these black armor guards has skyrocketed.

Having tasted the sweetness of critical hits, Duan Lingfeng wanted to perform a few critical hits, then he wouldn't be happy.

"Could it be that this critical attack is to kill this enemy in the most savage and ferocious way in order to be considered a critical hit? In the next few attacks, Duan Lingfeng just stabbed into the enemy's eyebrows and killed the enemy, and he didn't trigger any critical hits, which made him very depressed.

"Ding, congratulations to the host for successfully killing the enemy with a critical attack and getting a reward of 400 experience points. In order to experiment with this so-called critical hit, Duan Lingfeng mustered up all his strength to erupt, his anger was like a raging volcano erupting, just one blow, the black armor guard's head was blown off, and a cold system prompt sounded in his mind.

"Is it necessary to be full of anger and blow the enemy with the most savage and furious momentum, this is called a critical hit? Duan Lingfeng muttered to himself, as if he had touched some rules of the game.

In order to test whether his guess was true, Duan Lingfeng once again blasted the enemy's head, this time, because his mood was very calm, just to kill the enemy. Although the kill was successful, it did not trigger a critical hit, and it was just an ordinary skip kill.

When Duan Ling Feng's angry tyrant blows his opponent's head up, he once again touches the critical attack and is rewarded with four hundred experience points.
