A blood mist exploded behind Zhang Xu, and a hole with a thick diameter of the bucket appeared on him, and the air was full of the smell of blood, torn into powder by the resonance of compressed ultrasound, half of his body was shattered into a ball, and the internal organs, muscles, and bones were all turned together, permeating the surroundings!

The mutant bat didn't spare its hand, it was going to beat the person in front of him into powder, but it didn't expect it to make him dodge the fatal blow, and the piercing scream echoed in the air, so fast, it was really troublesome!

Without thinking about it, at the moment, he flapped his wings and turned into a black streamer, which could not give the prey in front of him the slightest chance to fight back, and the claws of the sharp hook opened and aimed at Zhang Xu's head!

"Drink~ It's too dangerous just now!" Zhang Xu shouted lightly, cold sweat mixed with blood stained the remaining half of the clothes, thinking back to the picture just now, he made the right decision between life and death, Zhang Xu in the air was originally sideways against the mutant bat, if he was hit by ultrasound, then it was a corpse that was cut off from the waist and broken into two sections, although he couldn't dodge it with strength, but he could still do it by turning around, using the centrifugal force that shook the blood!

It was the right half that was hit, this is to protect the heart, Zhang Xu's most important organ is the brain first, followed by the heart.

It's not time to recover now, the battle is not over yet, Zhang Xu just used Xuehe to stop the outpouring of blood, and looked up at the flying mutant bats, it seemed that he was going to kill them all!

smiled, the blood-stained cheeks were not a desperate smile, but proud, because Zhang Xu was not afraid of its compressed ultrasound, this skill limited his play, if it weren't for this trick, I'm afraid Zhang Xu would have killed the mutant bat without worries and took away the crystal of hope inside.

It's close!

Silently, Zhang Xu flipped his palm - the delicate dagger had been hidden in the boots for a long time, the carbon steel was glowing gray, and after multiple forging and tempering, its hardness was not ordinary.

The pupils contracted, and the black light in the distance disappeared in only a moment!

The battle is about to break out, the killing intent is everywhere, the right hand is flung hard, aimed at the head of the mutant bat, if you don't hit, you may be the end of the body, now it's too late to dodge its attack, if you hit, the winner of this battle will be yourself!

The speed of the throwing knife combined with the speed at which the mutant bat flew on its own, all of this was too late to react.

Mammals, even if the brain gives instructions, the main nerve transmission is about 100 meters, and it is known that mutant bats are more than 3 meters long, and the brain to the vertebral wings is also 1 meter, so it is estimated that it takes about 0.01 seconds to receive the instructions, and this 0.01 second time is uncontrollable, that is, even if the flying knife is in front of it, it will continue to rush forward, desperate!

It should be explained here that mutant creatures have minds and pre-evolutionary habits, and are not comparable to zombie creatures, if the mutant creatures die and do not take out the crystal of hope, then they will transform into zombie creatures, but there are pros and cons, the former can use wisdom, and the latter is not afraid of pain.

Poof!

The sound of a watermelon shattering exploded above Zhang Xu's head in an instant, and dark green blood mixed with brains rendered the picture, and Zhang Xu was suddenly dyed green.

Severely injured, he immediately walked over to the corpse of the mutant bat, took out a green crystal, wiped it with the broken clothes on his body, and swallowed it in one gulp.

The hanging heart finally fell, the tense body suddenly went limp, the slightest sweetness in the mouth seemed to be stained with honey, and he fell asleep despite the mud on the ground.

Since this is the territory of the mutant bats, other creatures will never be allowed to go wild here, and now that this territory lord has fallen, it is the safest in a short period of time!

……

The next day, Zhang Xu was lazy, his injuries were completely healed, his expression was somewhat numb, he moved his shoulder that was about to be broken, got up and searched among the heads of mutant bats, a dagger, which was still stained with disgusting brains, didn't look at it more, just wiped it a few times on his body, and then sent it into the quantum instrument.

There is still a lot of raw water collected from the water tower in the quantum instrument, which has not been treated at high temperatures, and now this stored water is very suitable for bathing, rinsing it with a large bucket of water, changing into clean clothes, and then going out of the tunnel.

Halfway through, Zhang Xu checked his condition, the gene unlock level was raised from 11.28 to 11.62, after experiencing the battle of the steel claw zombie and the battle of the mutant bat, he also devoured its Crystal of Hope, increasing by 0.34Lv, Zhang Xu was content enough, after all, the more he went to the back, the bigger the gap, and the difference between cloud and mud that can be said at the first level.

The injury has recovered, Xuehe has been working overtime all night, very competent, and Zhang Xu has one more change, X-ray analysis, his shoulder blades have become wide and thick, but the inside of the bone is hollow, the spine behind it bulges outward, and the sharp punctures in the flesh pierce the skin, flat like willow leaves, covered in a straight line, but there is no discomfort.

Zhang Xu was not stupid, he knew that this should be a new change brought about by absorbing the Crystal of Hope, and then his brain felt his back, and slowly, his back seemed to be heated.

Suddenly, the two ends behind him seemed to be pulled by someone, and I saw several white bones open, forming a pair of white wings, and the ends of each bone were extremely sharp, connected to a translucent membrane, showing gray-black, trying to fan, it was indeed possible, but it couldn't drive Zhang Xu to take off.

In fact, in ancient times, some people fantasized about growing a pair of bird's wings in order to go to the sky, but no one could succeed, but modern people will always have a guy who does not give up, so someone made an experiment, using nearly two meters of synthetic plastic, referring to aerodynamics, loading behind, but unfortunately to no avail.

For no other reason, according to biological experts, if humans want to fly like birds, their body structure must change.

Most of the skeletons of birds are hollowed out, which greatly reduces the weight of the body, and the body remains streamlined, if humans really become like this, it must be very ugly, so no one has bothered to pay attention to a pair of wings, it is better to study flying machines, such as modern hoverboards, light and small and extremely fast, but expensive.

There are no humanoid creatures that can fly just by having a pair of wings, and of course some people joke that this kind of thing can only happen to angels.

The bone wings are indeed unable to fly, but Zhang Xu tried it, the defense of the bone wings is very good, don't look at the thin and translucent wing membrane on it, but its toughness is so high, Zhang Xu didn't pierce it with a carbon steel dagger, and finally tried a shot of Oroque 30 bullets, and the result was no big deal, which shocked Zhang Xu.

It's a pity that you can't fly, it's a disadvantage, and you can't just look good!

Just as Zhang Xu was thinking about it, Xuehe sent a message, in Zhang Xu's mind was a bone tail, rubbing his chin, could it be that this bone tail also changed?!

Sure enough, Zhang Xu's bone tail also changed, and the bone tail was no longer as slender and flexible as it used to be, but became wide and flat, Zhang Xu knew that this must be a linkage effect.

The linkage effect, this is what Zhang Xu defined for himself, the so-called linkage means that the use of the two skills does not interfere with each other, but in special circumstances, if you need to launch the skill at the same time, there will be different effects, such as Zhang Xu's crazy python change, which is no problem in itself, but when Zhang Xu needs blood to fight, it will become a steel needle blood he, as well as the green ink bone sword and the blue poison bone tail, and the effects shown are even different.

Therefore, this effect will definitely be there, and now the bone tail and the bone wing should be linked, and the bone tail has changed because of the bone wing, and the bone wing has become different.

The wings that could have surrounded the entire body began to shrink and become smaller, and the skeleton structure became different, the top bracket bone began to fit Zhang Xu's arm, and finally it was connected to the inside of the arm joint, but there was no trace of pain, and the bottom was to fit Zhang Xu's waist, and the bones were also connected to the flesh and blood on the back, but there was no trace of abnormality.

This kind of appearance, Zhang Xu is already clear, he knows that there is a cute creature in the world, it is called a flying squirrel, it looks very much like a squirrel, the flying membrane of the flying squirrel can help it glide quickly in the middle of the tree, but because there is no organ like a bird that can produce resistance, it can only glide between the tree and the land.

Can't fly, but can glide, and the flat tail on the back may be used to control the direction, this skill has a lot of limitations, but there is also an extra way to retreat at critical moments.

Gliding? Zhang Xu nodded, this skill is very good!

Zhang Xu withdrew his bone wings, did not stop, and rushed to Qi Yiruo's place......

When Zhang Xu arrived, he knocked on the door for a long time and there was no response, and he shook his head at the moment, so he turned in from the balcony, at this time, Qi Yiruo was still lying on the sofa, with a delicate face under his unkempt hair, and crystal saliva flowed from the corners of his mouth from time to time, converging into a small river, piles of snack bags on the ground, and a fiery red mobile phone in his hand, and the game inside had not yet exited.

Zhang Xu turned around and entered a bedroom, didn't wake up Qi Yiruo, just lightly covered her with a blanket.

"Whew~" exhaled a breath of turbidity, Zhang Xu began to enter the state, just now he went to a hardware store and collected some tools and parts, he wanted to make weapons for himself and Qi Yiruo.

It just so happens that Zhang Xu likes to think about some small things in private in addition to physicalization, and now with Xiao An's assistance, it should be completed soon.

The sudden inspiration gave Zhang Xu an idea - the Hidden Blade, this weapon was inspired by a game, not only because it is handsome, but also practical in the last days, but this is for ordinary people.

When hidden in the cuff, it is easy to hide and kill enemies, and the sudden attack catches the opponent off guard, which is a more interesting weapon without firearms!

……

"Zizi~" Zhang Xu, who didn't need a protective mask at all, put down the welder in his hand under the dazzling light, and connected the last place by electric welding, a simple hidden blade was made, and the sleeve was gently buckled at the wrist, and the first generation of hidden blades was completed.

The corners of Zhang Xu's mouth curled, he likes to assemble, which is particularly rewarding, but his favorite thing is to assemble parts by himself, and he likes to modify weapons.

The full length of the blade is only 24cm, and it is only 3cm more than Zhang Xu's middle finger, but it is not used like this, the inner structure of the ring is simple, there are only a few springs, it cannot be fired, because it is too rough, and it will be improved later, but it can rotate 180 degrees, and the palm of the sword will hold the hilt after the blade rotates, which is very suitable for killing.

"Click-" turned the ring, and there was a crisp sound, and the blade stuck into the groove was aimed 180 degrees at itself, but if you clicked on the ring, it immediately bounced up, pointing at the tiger's mouth.

"Crunch~" Qi Yiruo pushed open the bedroom where Zhang Xu was, rubbed her eyes, and stretched comfortably, she woke up and saw the blanket on her body and knew that Zhang Xu was back.

Zhang Xu put down the Hidden Blade in his hand, handed Qi Yiruo a set, and taught her how to use it, but this weapon is not suitable for blatant use, ordinary weapons are used to confuse others.

……

"Pack up and go!" Zhang Xu was carrying a full backpack, draped in a black windbreaker, two Lockes were hidden around his waist, a carbon steel dagger was also placed in his boots, and a hidden blade was also hidden in the cuffs, but Qi Yiruo was not like Zhang Xu who was an evolutionary, and he disliked it too hot, so he threw it to Zhang Xu again.

There is a reason why Zhang Xu didn't give Qi Yiruo the Crystal of Hope, the Crystal of Hope has been tested to evolve together with Xuehe, and it will have a sense of awe and intimacy for Zhang Xu, Ma Wuheng and Zhao Yi are living examples, as if they are the offspring of the ontology split, and they have full respect for the mother, but Xuehe doesn't seem to want to separate the ontology now, so he keeps dragging it out.
