In 1973, due to the protracted war, science and technology in various fields are rapidly leaping forward with the demand, medical treatment, military, transportation, exploration, and among them, there is such a new industry that has achieved qualitative changes due to the huge output and supply - mechanical prosthetics.

In the confrontation on the battlefield, the ratio of human and alien forces has always been a disadvantage, although there are some powerful medical institutions as a backing, however, compared to the alien race that can still recover perfectly even after suffering the wound of the severed limbs, although the human race can ensure that the life of the soldiers can continue, however, all kinds of heavy injuries from the mutilation of the limbs are enough to make these brave soldiers say goodbye to the battlefield.

Therefore, a talented engineer, [Machinist] Don, put a lot of effort into this, and began to study for three weeks without sleep. Powerful yet sophisticated mechanical prosthetics began to be mass-produced in military factories, and soon the alien warriors were surprised to find that the soldiers who were supposed to be no longer present had made a comeback in full form, and that with the help of the weapon systems of the seemingly rudimentary steel prosthetics, they had even gained more combat effectiveness than before.

However, in the face of such a successful result, Da Lao Tang fell into deeper thinking-

Just as a prosthetic limb as a foreign object, it can bring such a significant increase in strength...... So, what if we fused humans with machines, and let the fragile flesh truly become a body of steel...... Will humanity achieve greater victories?

The answer is yes. Mercer tore off the tattered shirt on his body, revealing the true face of his body, "[Human and Machine Compatibility Test], I did the first batch of volunteers for that experiment, 2,782 people, and I am the only one who successfully accepted this steel body!"

Xuan Yi frowned slightly, except for the right half of his body, most of Mercer's torso had been replaced with mechanical armor, although it looked no different from the naked upper body of a normal man from a distance, however, after a closer look, it was found that the muscle groups that fluctuated and tumbled with the movement were actually bionic shells woven by tens of thousands of fine steel bars, and between the gaps that should have been called muscle textures, a dark green power source was emitting a dazzling light.

"Oh, I see, that's why no blood is coming out...... In retrospect, the kick that hit the target just now really didn't feel right. Xuan Yi sneered, but at this moment, his face began to be inexplicably gloomy, "I didn't expect this kind of experiment to be successful, you guy, did you give up your human identity for this little thing?"

"It's a little thing, it's a little bit, it's a completely shielded pain, it's the defense of a heavy tank, far beyond the weight and grip of a human being, and ...... The computing power fed back into the brain by the weaving of instant information, these miraculous superhuman powers are combined into one, and there is only - absolute victory!!" The loud sound of steam was deafening, the floor under his feet exploded, and Mercer, whose speed suddenly increased, swung out the mechanical left fist with all his strength towards the approach, Xuan Yi snorted coldly, and then met with the same heavy fist, the two fists collided, and the green light between the gaps in the mechanical arm was released dazzlingly, and a small shock wave spread out between the two, and the surrounding teenagers were shaken down almost at the same time, while Ying stood firmly in place, allowing the hurricane that broke out in the room to fly her black waterfall-like hair.

"Still a little bit ......"

……………

"Huh?" Anderson II, who had just kicked the two executives out of the door, suddenly shook the air behind him, "Who else is sneaking around?!"

"Cough cough cough cough ......! let go of the poor road is a friendly army! friendly army!!" I saw that in the direction that Anderson grasped, a rune paper fell leisurely, and then spontaneously burned into a cloud of ashes, and at the same time as it burned out, a strange Taoist priest who was pinched by his neck and feet off the ground was struggling in anger, obviously, he didn't expect that he would still be detected by people using the invisibility charm. And this product is none other than the Golden Tooth Daoist who wants to fish in troubled waters and sneak away.

"Human, I don't know you, let alone a friendly army, tell me your identity in three seconds, otherwise, I will pinch your neck. One...... Second ...... "Because the Golden Tooth Daoist was knocked unconscious by Xuan Yi and carried in as a sandbag, Anderson did not see his face, and at this time, due to the events that happened before, he was not in the mood to deal with this sneaky suspicious person in a good voice, and read it one after another in a few seconds, and at the moment when the word "three" came out, he was ready to shake his fingers and directly hit the other party.

"Stop, stop——!! I came in with Xuan Yi! Someone went to the top floor to assassinate him! Go and help! Hurry!" Seeing this critical moment, the Golden Tooth Dao Chief couldn't help but secretly scream bitterly, seeing that there were many enemies, he wanted to smear oil on the soles of his feet first and then redo his plans, however, he didn't expect that he was discovered before he even had time to step out of the door, and in desperation, he had to pretend to ask for help, and took the opportunity to tell the dangerous situation on the top floor.

"What did you say?"

Hearing this, Anderson suddenly raised his head and looked up, one of the characteristics of the High Blood Clan, the Eye of Insight, was immediately activated, and in his sight, the layers of heavy ceilings became transparent one after another at this moment, and when he saw the situation on the top floor of the casino, a cold sweat instantly slipped down his pale neck.

"Oh no, no, what's wrong! Mr. Xuan has an accident, His Royal Highness the Prince has to kill me!!" Anderson's cold demeanor collapsed instantly, and he immediately waved his hand and ordered, driving all the members of the security team to the top floor of the casino, and after that, he himself grabbed the Golden Tooth Daoist who wanted to sneak away, and the whole person turned into a huge group of bats like a black cloud with the Taoist priest, "Thank you for reminding me, thank you for your hard work, now, let's kill back together!"

Rely on it, rely on it! You kill you, don't pull me up!

Before the Golden Tooth Daoist could say a word of refusal, he was directly integrated into the swarm of bats, and poured into the cracks of the floor with Anderson......

…………

"Hmm......" Mercer raised his left arm, looking at the two shallow marks that had been cut out on it, and the corners of his mouth couldn't help but show a playful smile, "Why, senior, now, have you finally admitted that I am qualified to let you use weapons?"

Xuan Yi was silent, two short knives full of cracks fell in his hands, he shook off his windbreaker, and pulled out two large black star pistols from behind his waist, the sparks gradually burned, the green mist spit slightly, and he finally spoke-

"It's not a matter of disqualification. ”

Gritting his teeth on the body of the gun, Xuan Yi raised the muzzle of the gun and pointed directly at Mercer's eyebrows not far away, "The purpose of my trip this time is to visit old friends, no matter what, you are all his subordinates, his students, if I kill you, then I will not have the face to drink with him, I have dealt with you empty-handed from beginning to end, defeated without hurting my life, just for this childish reason." ”

"But now it doesn't matter. ”

Behind the lenses, Xuan Yi's eyes narrowed slightly, which was a precursor to the increase in his anger, "If that guy has such a subordinate under his hands who abandons himself and denies himself, but is still called [first], then it is necessary for me to replace him to correct your wrong and distorted thinking." ”

“…… Senior, what the hell are you talking about?" Mercer tilted his head slightly, although he could see that Xuan Yi was on the verge of exploding, he didn't understand what the other party was angry about.

"You don't need to understand, I'll make you understand right away. The muzzle of the gun burst into fire, and Xuan Yi pulled the trigger one after another, covering the barrage in front of him with absolute killing intent, the bullet casings flying, and the flickering light of the fire illuminated the black-rimmed lenses that he used to block his sharp gaze.

Mercer, the way you go...... is wrong!
