"No wonder, when I took it just now, it felt like it was heavier than yesterday," Wu Zong moved his mechanical arm as he spoke, "But it doesn't feel like it's big to put it on." ”

"That's because I'm equipped with hydraulic power," Zhang Yi tilted his head, then gestured with his left hand to a pistol gesture, and said to Wu Zong, "You try to do this." ”

Wu Zong took back his three fingers as Zhang Yi did, and only his index finger and thumb stretched out.

Immediately after that, I heard a soft click, and a small opening suddenly opened on the underside of the palm of the mechanical arm.

"What is it?" Wu Zong didn't dare to move, turned his head and asked Zhang Yi.

"Guns. Zhang Yi raised an eyebrow.

Wu Zong then remembered that before leaving yesterday, Zhang Yiguan was going to leave the Colt python pistol, but he didn't expect it to be loaded on this.

"Only the rifling design and firing device are retained, which makes it more convenient to hide the gun body," Zhang Yi continued: "Of course, in order to save space, it only has four rounds of ammunition, counting the total five rounds in the chamber. ”

"Of course, it may sound a little little," Zhang Yi continued, "That's because you only have .45 ammo, and I have reserved some upgrade space, and I can upgrade to .50 ammo if I have resources in the future." ”

Wu Zong nodded secretly, as Zhang Yi said, it is true that only five .45 caliber bullets do not have much effect, but if they are replaced with .50 caliber bullets, tsk, Wu Zong smacked his lips in his heart when he thought of the terrifying bullet with a diameter of 12.7mm.

If the kinetic energy is enough, it is enough to punch through a 15mm thick nickel-chromium steel plate.

"I also added some other things," Mr. Zhang said, "such as a flashlight." ”

As soon as Zhang said this, Wu Zong saw that the back of the mechanical arm's hand lit up, which should be controlled by Echo.

"You almost blinded me," Wu Zong rubbed his eyes that were shaken by the wolf's eye flashlight: "Shouldn't the flashlight shine forward, how uncomfortable it is for you to use it from the back of your hand." ”

Indeed, the light source of this flashlight is emitted from the back of the mechanical arm, and if Wu Zong wants to see clearly the direction in front of him, he must have the back of his hand facing his face, this design does look a bit anti-human.

And it's a bit of a middle two, Wu Zong did this action, and he felt a bit like an armored warrior.

"It's to go with something else," Zhang Yi waved his hand and said, "Echo, activate the defensive shield." ”

As Zhang Yi's words fell, Wu Zong only felt the mechanical arm vibrate, followed by a crisp golden sound.

Zheng!

The outside of the mechanical arm suddenly sprouted a number of dense metal strips like a spring knife, and exploded, forming a small diamond-shaped metal shield that was only about 30 centimeters wide.

Zhang Yi stepped forward and touched the metal shield: "In this way, you can detect the shield in the dark, and you can still use this thing to block it if there is an accident in front of you." ”

"I originally wanted to make it into carbon steel, so it is light and explainable," Zhang Yi shrugged helplessly: "But there is no here, if I can find better materials in the future, I can try to upgrade you." ”

"Of course, daily climbing is also necessary," Zhang Yi continued: "There is a winch wheel between your two arm bones, and the winch wheel is wrapped around a ten-meter-long polymer steel cable, which is the strongest and thin cable I can find so far, and the hook claw will shoot from the side of your wrist, and the hook claw and steel cable can bear the weight of three hundred kilograms." ”

Speaking of this, he yawned, patted his mouth wide open, and continued: "There are also some strange things, such as small repulsion cannons and the like, if there is a place that can be used, Echo will tell you directly, I won't introduce them one by one." ”

Then, Zhang Yi took out a small wireless earphone from his pocket and threw it to Wu Zong: "This is a wireless headset, which can be connected to the built-in Echo processor of the robotic arm, and you can communicate with her at any time." ”

"Can you go anywhere?" Wu Zong asked.

"Of course not," Zhang Yi shook his head: "Because the bridging network can only cover the academy, so only in the academy can Echo be able to analyze and consult a large amount of data, once out of this range, Echo does not mean that it will become an artificial retard, but it will definitely not be as smart as here." ”

Zhang Yi waved his hand to comfort Wu Zongdao: "But you don't have to worry too much, because no matter where you go, as long as the robotic arm has electricity, Echo will definitely assist you perfectly in controlling the robotic arm." ”

"Then how long will this thing last," Wu Zong noticed that there was a three-centimeter-square glowing rectangular bar on the inside of his arm, which was divided into three scales, which should be the power reserve of the mechanical arm.

"If you use it normally and don't use it for combat purposes, it can last for about ten to twelve hours," Zhang Yi said, but then added: "But it's almost unlikely, so usually as long as it's not too intense in combat, it can last about eight hours, of course, if you don't usually use it, you can let the Echo control it into sleep mode, so that it can last longer." ”

Wu Zong shrugged his shoulders and was noncommittal to Zhang Yi's design: "Wouldn't it be a waste to install it." ”

"That's just right," Zhang nodded, yawning again, he was indeed too sleepy: "Finally, I will remind you of two points." ”

As he spoke, Zhang Yi stretched out a finger: "First, there is a high-frequency EMP bomb built into the mechanical arm, which can disable all electronic products within a radius of one kilometer after exploding, from small pacemakers to large electronic turrets, all of which will be scrapped." Be warned, however, that once detonated, both your robotic arm and your Echo will all fail. ”

Then he held out a second finger: " Second, the power source of the robotic arm is a small flywheel battery, the reason why you use this kind of thing is because you have a grid laser cannon in the palm of your hand, don't be so surprised, this kind of thing was developed by the United States as early as the nineties, last year the laser cannon developed by the German Rheinmetall company has been able to shoot down the drone, but the cost is too high to be used in the war on a large scale, I made you a small miniature version, although you can't shoot down the plane, but it should be no problem to penetrate the steel plate or something. ”

Wu Zong's mouth has been opened into an 'O' shape, he has not seen high technology, the superconducting magnetic current propulsion cannon launched by the human base in the endgame of the last life was developed in the last ten years, what really surprised him was Zhang Yi, this person's intelligence and technological level were already outrageously high.

"Don't worship me so much," Zhang Yi waved his hand angrily: "This thing is also flawed, it will drain your flywheel battery in an instant, and make the mechanical arm and Echo ineffective like the EMP bomb, but it is quite powerful." ”

As he spoke, Zhang nodded as if affirming himself: "Well, it should be quite big." ”

"Should it be quite big?" Wu Zong grabbed Zhang Yi's point: "What do you mean by should?"

"It should be ......" Zhang Yi scratched his head a little embarrassed: "Even I haven't tested how powerful this thing is." ”

Wu Zong looked at Zhang Yi with a question mark on his face: "Are you sure you won't up?"

Zhang hesitated for a moment, and did not answer Wu Zong's question, but quickly said: "Please leave the matter of food to you, I'm too sleepy, bye." ”

After speaking, he slipped out of the gate as if fleeing, leaving only one sentence: "Echo!

"Roger,"

Wu Zong was just about to chase out, only to hear the speaker above his head ring, and Echo's calm female voice sounded: "Wu Zong, the highest authority has been opened, please enter your voice recognition lock." ”

"Huh?" Wu Zong was a little confused, spread his hands and said, "What sound recognition lock? What should I say? Zhang Yi didn't tell me how to get it?"

"The entry is complete, and it has been added to the highest permission database. ”

Before Wu Zong could react, Echo had already completed the identification based on his words.

Wu Zong scratched his head, without Zhang Yi's guidance, he felt a little at a loss standing in this studio.

He asked, "Echo, is there anything else I can do?"

"Sir, my supreme authority has been opened to you, and based on your previous conversation with Mr. Zhang Yi, I think you should go and find food. Echo replied.

"Okay," Wu Zong nodded, turned his wrist and looked at the inside of the mechanical arm, the three grids had enough power.

Wow - Wow - Wow -

With two almost inaudible mechanical sounds, Wu Zong shook his mechanical iron fist and said with satisfaction: "Let's go!"

Wu Zong still kept an eye on it in the end, and after consulting that the Echo bandage would not affect the performance of the robotic arm, he still picked up the bandage on the ground again and wrapped it around his left arm, in order to be less eye-catching—although there were not many 'people' now.

After explaining a little to Li Bing and the others, Wu Zong originally wanted to act on his own, but considering that he couldn't get too many things in one trip, he simply brought Fang Laosan to move things with him.

The supermarket is in the academy, northwest of the tech building where they are located, not far from them, only about two kilometers, which will be within the coverage of the Echo.

"Are you ready," Wu Zong looked at Fang Laosan, who was a little nervous beside him.

He is holding a metal ball stick, and for ordinary people, it is the best choice to choose some blunt weapons as weapons in the last days, because this can not only effectively knock zombies away, but also not get stuck in the flesh and blood like sharp weapons and cannot be pulled out.

Fang Laosan licked his lips and nodded to Wu Zong: "Okay." ”

Wu Zong put on the wireless headphones, and then tapped the yellow button in front of the door.

Rumble –

With a long sound of metal vibrating, the heavy door on the fourth floor slowly flipped up, and a corridor covered with sunlight appeared in front of the two of them.

"Let's run after taking something," Wu Zong explained to Fang Laosan as he walked: "Follow me, everything is under my command, if there is any accident halfway, don't think about it, immediately throw away the bag and run, we can take the things again, but there is only one life, understand?"

"Understood," Fang Laosan took two deep breaths and nodded.

While talking, the two came to the first floor, and Wu Zong pushed open the door.

It looked like it was supposed to snow last night, and there was a thin layer of snow on the ground, but it had been trampled into mud by messy footsteps, and the sun was pouring on the ground, and a breeze blew the bare branches outside the door, and the scattered snow on them also fell in a torrent.

If it weren't for the end of the world, Wu Zong would definitely stretch out and scream comfortably.

But not right now.

Because he saw a circle of zombies kneeling on the ground less than thirty meters away from him, there were about four or five of them, and from such a distance, Wu Zong could hear the sound of them chewing human flesh.
