"Ahhh~!"

The cast gauntlet spewed out a large amount of white water vapor, burning the skin on Yun Hong's shoulder, and the dark red color quickly dimmed, leaving deep red cracks, and the cracks gradually brightened and darkened like the breath of a living thing.

The refining gust drawn with the blood of Kabane disappeared, Yun Hong's body fell straight to the living room floor with a thud, sweat wet his clothes, he panted and exhausted his breath and turned his head to look at the left hand that he had transformed into a mechanical arm, the same body was dark black, the style was a combination of cold weapon armor and sci-fi beauty, at first glance it was the armor covering the left hand, but the actual interior was composed of hundreds of thousands of complex parts and refining arrays.

In exchange for the knowledge of truth that the villain in the bottle had obtained, and thanks to the universal metal material such as the heart membrane in Kabane, this mechanical prosthetic leg will be an important means of saving his life in such an environment.

"It's so dangerous, I almost got away." Yun Hong smiled bitterly in his heart, squeezed the last of his spiritual power, and his right hand trembled, and he took out an A4 paper that had been drawn and refined.

"Gollum!"

A wonderful sound sounded, and the concrete on the ground surged into a coffin-sized cuboid that wrapped Yun Hong's body inside, leaving no means of getting out except leaving a breathable hole. This was the second layer of protection he had made for himself, so that even if Kabane came to his home, he would not be easily aware of his presence.

Yun Hong was so tired that his mental and physical strength were exhausted to the extreme, so he had to enter a deep sleep to recover his mental and physical strength.

As soon as his eyes closed, his drowsy consciousness sank into the endless depths of consciousness, and for a second his consciousness cut off all contact with his body.

The knowledge given to him by the villain in the bottle contains a deep sleep method specially designed to restore physical and mental strength, and the mental power is equivalent to a full day of sleep when the consciousness enters sleep, and the mental power is equivalent to a full day's sleep, at the cost of throwing his body into the sea within these two hours, he can't wake up.

In the last days of the race against time, Yunhong must take this risk.

······

"Boom!"

I don't know how long it took, but an earth-shattering loud noise woke up the sleeping Yun Hong, and he could feel a strong vibration in the crust made of concrete.

In the dark, Yun Hong waited for a few minutes to make sure there was no abnormality, he slowly raised his steel left arm to touch the concrete, and the built-in refining array launched the destruction of the concrete structure, and when he came out, he found that the living room was in a mess, and there was no trace of Kabane's coming, like a strong shock wave shattered the glass in his living room, and the metal of the window sill was all twisted and scrapped.

The entire city circuit system was completely paralyzed, and the city was shrouded in darkness.

Yun Hong's first time was to feel the changes in the left hand of the machine, the left hand of the machine is the nerve center that directly connects him, and the degree of flexibility and reaction ability are no different from the real left hand, and the biggest difference is probably that the left hand cannot provide real touch. After a few movements of his left hand to make sure that it was okay, he walked to the window to carefully observe the situation outside, and in the distance of the town he could see a mushroom cloud rising into the sky, and the burning fire stained half of the night sky red.

"It should be an attack with modern weapons, and this direction is remembered to be the direction of the air raid siren, well~ That is to say, the siren may be to attract the attention of Kabane and then use weapons of mass destruction to solve it at one time, and the country also has such a response ability, which indicates that at least the disaster in Kabane is not as serious as imagined, otherwise this means of elimination will not be used in a fringe town that is not special."

"Now is the best time to escape from the town, the air raid sirens that attracted Kabane's attention are gone, and the Kabane group may return at any time, and I don't know how many gathered Kabane can be eliminated by that weapon of mass destruction just now."

"There's one place to care about, maybe that's the source of Kabane's invasion of this world."

Yun Hong stared at his mechanical left arm, the dark red crack on it disappeared, it looked pure on the surface, it was a mechanical arm, alchemy and modern knowledge combined with the heart membrane of Kabanei to create, the main function is not a powerful physical ability, it is a plural refining array built inside the arm armor. Yun Hong used the human body to refine and lost his left arm in trading with the Gate of Truth, and now Yun Hong also has the ability to refine without a formation, but drawing a refining array in advance can greatly save the physical and mental power consumed by launching alchemy, which is of great help to a third-rate alchemist like him.

The mechanical arm can exert physical power beyond the limit, of course, it does not mean that Yun Hong can lift a vehicle weighing several tons casually, the mechanical arm can do it, Yun Hong's other body parts are flesh and blood, and a few tons of things can make his knees shatter.

"Click~!" Yun Hong flicked his left hand, and a cold cold light popped out from the mechanical arm, the width of the blade was the same as the width of the arm, about half a meter long, the center part was hollow, and the whole body was bright black, and the cold and bright color of the blade in the dark environment made people have no doubt about its sharpness.

"It's very comfortable, and you can cosplay it if you have nothing to do in the future." Yun Hong's left hand loosened, and the cold blade disappeared.

The mechanical arm blade is very similar to the weapon of a character named Robber in the game he often plays, League of Legends.

The surface of the weapons strengthened with the heart membrane of Kabanei in "Kabaneri of the Iron City" all show the same blood patterns as Kabane's body, but Yun Hong's mechanical left hand will not, because he has completely analyzed the elements of the heart membrane and fused with the materials used to create this mechanical arm, and the gap between them is not enough to describe with the qualitative changes.

"And then there's the ranged attack capability."

"Click~!" The mechanical arm changes again, with delicate composite crossbows stretched out on both sides, the bow and crossbow mounted on the mechanical arm are small in size, and their lethality is not bad, and the strings of the crossbow are made of special metals, and the lethality of the crossbow is no worse than that of modern sniper rifles. There is also a reason why he didn't make a firearm, his crossbow can fire crossbow arrows or steel balls, the material is very convenient, and a refining array can extract hundreds of crossbow arrows or a random number of steel balls from the city building, and the lethality can easily penetrate the heart membrane of Kabane, if it is replaced with a firearm, making bullets has become a very troublesome step.

In addition, the bow and crossbow always have five rope bolts, which can be fired at the wall to allow Yun Hong to quickly escape from danger, like a small simplified version of the three-dimensional mobile device in "Attack on Titan".

Yun Hong found a loose set of clothes to change into, and then he planned to go to the place that made him care.

When I used the refining array to mobilize the elements of the earth's crust just now, I found a place that was incompatible with the real world, where there were many strange material elements that did not exist in the real world, and I could clearly feel the chaos and conflict, and it should be the entrance and exit of the world if it was not surprising.

"I'll have to go over there and make sure, it's just the opposite direction of the air raid sirens, and I shouldn't encounter a lot of Kabane."

In front of the door, Yun Hong took a deep breath and stepped out.
