"Is there an alloy that can defend even high-melt bullets?" Zhang Zhen is not worried about the power of the chariot, the Tomahawk now uses less than 50% of the power, and it is not an air war, what should he do so quickly.

Hu Hai pondered: "I once heard that some scientists have created a new type of diamond alloy, using this black gold ore, they solved the problem that the alloy will decompose at high temperatures, I heard that it is to add special minerals and use different pressing processes, although the alloy will decompose into a liquid state after high temperature, but there is a net inside that will make the liquid not scatter, and it can form an alloy after colding, which is the strongest defensive alloy at present." ”

Zhang Zhen opened the system to study the upgrade of the chariot, the defense value of the chariot depends on the material of the chariot, but there is energy to add a layer of protection, and the material will be automatically refined into the best metal that can be refined when it is upgraded, that is, as for how to make alloys, it may not matter, as long as there are corresponding materials.

"Then you continue to study, I'll sleep first." Zhang Zhen felt sleepy, and he was a little tired of fighting Xiao Rong for 300 rounds today, so he pulled Shelley to rest.

Hu Hai struggled all night, and even Leia, who had been careful about the embankment, had forgotten about it, and had been studying electromagnetic equipment, and the electric sparks in the villa flickered as if it was flashing and it was going to rain.

When Zhang Zhen got up and washed his face and went downstairs, he saw that Hu Hai was still busy, two things that could be held in the palm of his hand were placed on the table, and Hu Hai was busy testing the fixing bolts at the joint of the iron gun.

"This is electromagnetic equipment?" Zhang Zhen took one in one hand and looked at it in the palm of his hand, it looked like two iron shells, and there was no suction when he tried to put them together.

Hu Hai put down the work in his hand and stood up and said with a smile: "My lord, it is not turned on now, the metal ring on it can be rotated, the middle is closed, and the left and right are magnetic poles." ”

Zhang Zhen looked at his right finger and pulled out the metal ring of the electromagnetic equipment in his hand, and with a snap, the electromagnetic device in his hand suddenly took off his hand and absorbed the iron door on the side, and reached out and pulled it without moving, feeling like it was welded on it.

He pulled the iron ring back into place, and with a whoosh, the electromagnetic equipment instantly broke away from the iron door and fell down, and hurriedly reached out to catch it.

"Magnetic force can drag an object of 200 catties within three meters, and the distance of ejection is about five meters, and the strength plus the alloy gun I estimate that it can penetrate the D-class defense plate." Hu Hai said excitedly.

"Well, I'm looking forward to your results, I'll do it for you today's breakfast." Zhang Zhen put down the electromagnetic equipment, feeling quite dangerous, if he accidentally clamped his fingers, it was estimated that he would have to be crushed.

"Thank you for your concern, Lao Hu will definitely succeed." Hu Hai hurriedly squatted down again and continued to polish the alloy iron gun to prepare for the installation of electromagnetic devices.

Shelley woke up and looked at Green Shield, and found that there were zombies invading at night, and crawled to the roof of the building with a sniper rifle on his back, and Sakura followed curiously.

Zhang Zhen went into the kitchen and cut two potatoes, cut some meat, cut some cabbage or something, and directly added rice and water to stew it, feeling that as long as the salt is put in place, it will not taste wrong.

But when I ate it, I found that the taste was really not very good, I only ate a small bowl and didn't eat it, but Hu Hai and the others still ate the delicacies of the mountains and seas, and without chopsticks, Sakura was also happier to eat, but Leia tried to feed the spoon into her mouth a few times awkwardly, and directly threw the spoon and grabbed it with her hands.

Zhang Zhen picked up the alloy electromagnetic gun that Hu Haicai had successfully installed and played with it on the side, put the two iron guns together, the gun body was gently glued together, and it was easy to pull it away with a hard pull, and pulled the metal ring of the gun body with his hand, only to hear a click, the two gun bodies suddenly merged into one in his hand, and then he dragged hard It is really difficult to pull open a slit.

I pulled out the metal ring of the upper half of the gun and could only pull it to the side, and then tried to pull out the lower half of the gun, and suddenly clicked, the first half of the gun flew out like a rocket, and then there was another chirp, and the head of the gun was suddenly nailed into the stone wall of the room.

"Big ...... Adults be careful. Hu Hai found that being busy was a reminder.

However, it was too late, Zhang Zhen curiously pulled out the metal ring to the other side, and as soon as he pulled it out, he felt that the half of the iron gun in his hand was suddenly dragged forward by a huge force, and the person suddenly pounced forward a few steps, and with a bang, the gun body stuck to the gun head on the wall before stopping.

"I'll go, this power is not small." Zhang Zhen looked at him in surprise, this drag dragged him two meters, and the strength was so great that he almost felt like his feet were off the ground.

Hu Hai hurriedly came over and said, "My lord, the power of electromagnetism is not small, use it carefully." ”

Zhang Zhen nodded, pulled out the gun from the wall and said, "This magnetic ring control is not easy to use at the interface." ”

"Hu Hai has already made the control chip, but he doesn't know how to use this gun, so he hasn't installed it yet." Hu Haidao.

Zhang Zhen saw Sakura finish eating and beckoned Sakura to come and said, "How do you feel about this gun as your weapon?" ”

"For Sakura?!" Sakura was pleasantly surprised to take it in her hand, holding it in the same posture as she used to use the spear.

"Yes, a normal spear or iron spear is too small for you to compete with the enemy, and this electromagnetic gun will make you more ferocious and agile." Zhang Zhen looked at Sakura's habit of holding a gun with a gun, pointed to Sakura's hand and said, "Old Hu, adding control here can make Sakura easily control electromagnetism." ”

"No problem, I can add it right away." Hu Hai nodded.

Zhang Zhen is also convinced, Hu Hai really did what he said, and it didn't take ten minutes to add a ring-like metal ring to the handshake position, and his fingers could easily pull out the magnetic energy to control the two electromagnetic devices.

He opened all the protection of the villa and took Sakura out to test the gun, and Leia rushed out of the villa into the wilderness like a leopard.

Zhang Zhen looked at the black but mirror-like iron gun and sighed, now he has mastered the use of ammunition and retraction, and pulled to the right side of the ground five meters away, swished, his hand felt a slight shock, the head of the gun shot out suddenly, and it pierced into the ground five meters away, and the entire front half of the gun body was almost completely submerged in the soil.

The finger was pulled to the left violently, only to see the head of the gun violently vibrate in the soil, and his body felt a little dragged forward, so he had to firmly hold his foot, only to hear the sound of breaking the earth, the head of the gun suddenly flew back upside down, and slammed into the interface, which shook his wrist.

"Good thing, Sakura, you can try it." Zhang Zhen excitedly handed it to Sakura, Sakura may not have guessed how he wanted Sakura to use it, it was really a whimsical idea.

Sakura took it in his hand and looked at Zhang Zhen and said, "Master, how do you use Sakura?" ”

Zhang Zhen smiled: "Just like when you hunt, run quickly towards the prey, and then eject the head of the gun halfway, and the person also jumps out at the same time, and then you are turning to absorb and see what happens." ”

Of course, Sakura didn't know what would happen, and when she heard Zhang Zhen's command, she didn't hesitate to hold the electromagnet gun and run out like a leopard, and when she ran to the fastest, she raised her wrist and ejected the head of the gun, and the person also instantly flicked out of his legs, and the person's vertical jump was more than a meter high, and he quickly pulled the metal ring to turn to suction.

I saw a swish, and was suddenly pulled forward, and his body lost control and flew out of control for more than a meter and fell to the ground.

Zhang Zhenxin wondered, is he too whimsical, this kind of thing can only be done in movies, how can it be done in reality.

Worried about Sakura's injury, Sakura got up from the grass, then quickly began to leap again, then ejected the spear head and began to pounce, and then started to suck, and once again lost control and fell to the ground.

"Sakura, come back, be careful of getting hurt." Zhang Zhen felt that it was impossible to complete it, and due to the influence of gravity, even Sakura, who was as strong as a leopard, could not complete the flash in the air with an electromagnetic gun.
