Lu Tian observed it and found that the knife that had just been cut on this guy's neck had just broken the black hard shell outside, and he couldn't help but marvel at the defensive power of this shell, the hard shell on its neck was particularly thick, and he didn't know if it could be solved within ten knives.

The blade of Wuhuang is slender, compared to this big man, it is like a child's toy, but at this time, it is a little frightened, just now Lu Tian slashed the wound on its neck with a knife, and it has already produced the instinct of a beast to run faster.

If it still had two arms at this time, it might be able to stop Lu Tian. But now it has become a target, and it can only howl, revealing its foul mouth that is a few points bigger than the horse's mouth, so smoked that Lu Tian can only chase it with bated breath.

"Damn, it's curled up, this guy's bones are so hard!"

After slashing again, the feeling of cutting iron made Lu Tian a little depressed, and what was even more depressing was that he found that the blade was actually a little curled.

He knows that Wuhuang is sharp, and he can be said to be the best weapon he has ever seen, although he has not reached the point of sharpening iron like clay, but there is basically no problem in cutting things and killing zombies, but at this time he was actually slightly curled.

This guy's status in Lu Tian's eyes has improved a little, bullets can't penetrate it, ordinary knives and guns can't take it, it can be regarded as a good hand at charging into battle, if it is bigger and stronger, it can really be regarded as a humanoid tank.

"It's a pity that I don't have armor-piercing bullets, Xiao Qi, armor-piercing bullets should be able to easily penetrate this guy's shell, look at this appearance, its shell is a few centimeters at most, and it shouldn't be able to block armor-piercing shells that can penetrate tanks."

Lu Tian was a little distressed about Wuhuang in his hand, so he temporarily stopped cutting off its head, and slowly followed behind.

"Master, of course you can, the armor-piercing bullet can penetrate dozens of centimeters of steel, this guy can't stop it, but if it is raising two levels, and the turtle shell is increased ten times, it should be no problem."

"It's tricky!"

Lu Tian's contempt for zombies has slowly disappeared, and the zombies he thinks are brainless, so it is inconvenient for intelligent mutant zombies to appear, and it is estimated that the level of wisdom is no less than that of a ten-year-old child.

He used to cut zombies like chopping vegetables and melons, but when he encountered this big guy, he found that the zombies' defense power could reach such an amazing level.

The various abilities evolved by these zombies have refreshed his cognition, making Lu Tian feel that the future world seems to be their stage.

"Xiao Qi, help one, I want to cut off its head with a knife, what is the best way?"

Seeing that the big man didn't affect his speed much because of the wound at all, Lu Tian was also a little anxious, and some didn't want to damage Wuhuang.

"There are a lot of ways, there are two kinds of fast ones, let Xiao Qi shoot directly, consume a chance to shoot, this guy is just a little meaning! You can also spend energy to make the master's knife sharper, depending on how the owner chooses. ”

"How much energy does the second flower have?"

Xiao Qi's opportunity to make a move is very precious, although it will be refreshed every day, but until the end, it is better not to use it, who knows when there will be a danger of falling from the sky.

"5 orange energy points, cast a small spell, translated into the meaning of Chinese civilization, it is probably called sharp art, which can improve the sharpness of the weapon, so that Wuhuang has the sharpness of the lowest level spiritual weapon thirty percent, the duration is one minute, does the master want to start?"

"Yes, let's get started!"

Lu Tian got thousands of orange energy points yesterday, and at this time he had the feeling of being an upstart, and it seemed that there were not so many orange energy points at 5.

"Drop! Sharp Technique is successfully performed, costing 5 orange energy, and the owner has 1780.9458 orange energy left. ”

The air fluctuated slightly, and Lu Tian saw a little light appear on the slender blade of Wuhuang, just like the blade was emitting orange light, and a sharp aura emitted, as if anything could be cut.

The time was only one minute, and now 3 seconds had passed, Lu Tian didn't want to waste time, and walked away with an arrow step, Wuhuang turned into a faint orange thin line, and instantly reached the wound where there was still dull blood.

Multiply~

A slight friction sound sounded, a slight sense of obstruction came, and the corners of Lu Tian's mouth smiled, and Wu Huang crossed the thick neck of the big man, with a few traces of blood, exuding a warm forehead.

The speed of the big man decreased instantly, and after taking a few steps up, he seemed to want to roar, but he was stuck in the neck, and fell to the ground with a bang, the ground was dusty, a huge head was separated from the body, and blood spurted out like a spring, wetting the ground.

The slightly inclined incision was relatively smooth, and dark black blood kept coming out, and the zombie twitched a few times before finally dying.

Then the blade still had the effect, Lu Tian used the knife to slash at its bucket-sized head, and the skull was a little harder, but fortunately, with the assistance of sharp arts, Lu Tian spent a little more effort to split the head.

The tip of the knife moved a few times in the shrunken yellow and blackened brain marrow, picked out a solid, took out a piece of paper and wiped it a few times, and the energy core of this level 3 mutant zombie appeared in the sunlight.

An oval-shaped solid the size of a pigeon's egg, the material and weight are a bit like crystals, showing a translucent state, with a pale red body and strong energy fluctuations.

This is the first time Lu Tian has encountered the energy core of a high-level zombie, and the current ordinary zombie energy core is still semi-solid jelly-shaped, and the second-level one will become solid, and the color will change from water color to light red, a bit like the inner dan of a beast, but it grows in the head.

"25 points of red energy, which is equivalent to the sum of the energy of more than ten ordinary zombies, this guy is still powerful or its shell, and this energy core is secondary."

As Xiao Qi absorbed, the energy core in his hand lost its luster and was thrown aside by Lu Tian, he carefully observed the corpse of the large zombie and roughly saw the reason why it had such a strong defensive power.

Its shell is somewhat like an insect-like exoskeleton, the bones are extremely dense, and the muscle tissue is also very tough, making its body more than ordinary weight, no wonder it makes a thumping sound when stepping on the ground.

The size of this zombie is far beyond that of humans, and even if it is dead at this time, it is quite shocking.

"Master, wait a minute!"

Just as Lu Tian turned around and was about to leave, Xiao Qi suddenly stopped Lu Tian by opening his mouth.

"Anything else?"

Since Xiao Qi opened his mouth, naturally there is something wrong with this zombie.

"Master, break open its heart, there's something good in it."

Fortunately, there were still more than ten seconds left in the time of the sharp technique, and Lu Tian took the opportunity to break open the zombie's chest, unlike what was expected, its heart was not rotten or obscene, but extremely strong, beating slightly.

The tip of the knife was gently inserted into the heart, and bright and warm blood burst out, and Lu Tian twisted to dodge it.

A look of surprise appeared on Lu Tian's face, he didn't expect that there was such vitality blood on the zombie's body, and even the energy it contained was far more than that of humans.

"Master, this is something that only zombies of level 3 and above have, at this time, their ** is extremely powerful, and high-energy substances will begin to be bred in the body, and this guy's energy matter is in the heart."

Following Xiao Qi's words, Lu Tian really saw a ball of blood emitting a faint light, and dug it out with his hands, and the blood condensed, like the essence blood of a martial arts powerhouse.

"What's the use of this, can you eat it directly, but there should still be a virus in it, right?"

"Master, there are viruses but not many, because this mass of essence blood contains quite strong qi and blood, the number of viruses is already very rare, if this mass of blood continues to absorb energy, to a certain extent, it can be completely turned into the power of qi and blood, at that time, even if it is a semi-energy substance, it is difficult for natural viruses to survive."

"Of course, this thing is not of much use to the master, and it also contains a lot of viruses, but after treatment, it can help the master's subordinates strengthen the body, which is much better than the strong body fluids of the ZK2 type."

"That's not bad, you can take it for me!"

The value of this thing is worth Lu Tian's attention, but he didn't expect that there are some good things on this zombie.

"Anything else?"

"Yes, the shell and bones of this mutant zombie contain a special mixed metal component, which makes it have such a powerful defensive power, and this mixed metal is not available on the earth, Xiao Qi has never seen it, maybe it is a special product brought by this virus, it is very valuable."

Lu Tian was stunned, he just asked casually, but he didn't expect it to be there.

"That's up to you, if you spend less energy, you can shoot directly!"

According to Xiao Qi, if you want to get the metal components contained in his body, a special refining process is necessary, and he must be helpless.

"Okay, master, spend 3 orange energy points, go on?"

"Continue~"

A faint light enveloped the zombies, and after a while, it gradually faded, and the original black shell became a little gray, as if it had lost its bareness, and a fist-sized pure black metal appeared in front of Lu Tian.

"It feels like it's about the same density as iron, and I don't know what its characteristics are."

Lu Tian took it, felt it in his hand, and asked softly. "The characteristics are somewhat similar to titanium alloy, but the material is a big level higher than it, and it has a very good memory function, which is very suitable for creating weapon armor, and it is a very cherished alloy, Xiao Qi didn't expect that this kind of zombie corpse could be synthesized with this composition, because it is a new variety, so it does not have its name."

"Well, Xiao Qi, you did a good job!"

Lu Tian praised it slightly, and Xiao Qi helped him find all the valuable things, which made him feel very good.

Didn't care about the zombie anymore, Lu Tian quietly returned to the team, and he was greeted with shock, admiration, and curious eyes, although these people were sniping ordinary zombies, they were still distracted to see the situation on Lu Tian's side.

Such terrible creatures died at the hands of this unattractive man, and they really discovered that there were humans who could be so powerful, and even that kind of monster could be easily dealt with by this person.

In their eyes, it had taken less than three minutes for Lu Tian to kill the big monster, and when they used the bullet to strafe it just now, they hadn't even broken its shell.

Sure enough, there is a difference in this world.
