The Mark IV's test machine uses an alloy doped with titanium metal like Iron Man in the movie.

It is used on the satellite created by Qin Lu, and it is also the metal on the moon exploration satellite, so it is not cheap.

"Sir, this is the assembled armor!"

The Mark IV test machine already has the ability to stand independently, so what is placed in front of Qin Lu is a complete silver-white steel armor.

"It looks very beautiful!" Qin Lu said with a smile.

"Yes, sir, it will be even better when worn!"

Jarvis Road.

"What are you waiting for? Come on!" Qin Lu said, walked to the Mark 4 test aircraft and said to Jarvis.

"Okay sir!"

As Jarvis finished speaking, the reactor on the armor's chest began to shine, and then the armor quickly opened from behind. It took less than five seconds from Jarvis's speech to the complete opening of the armor.

"Good, this effect!"

Qin Lu nodded, then stood in with his foot.

After standing in, Jarvis began to detect Qin Lu's combat power.

"Sir, you can start closing!"

"Yeah, close it!"

Qin Lu nodded. In addition to the necessary reactor and internal transmission shaft on this armor, even the thruster was not installed, so he was not afraid of explosions or anything else.

After Qin Lu said that, Jarvis began to close the armor.

When I was locked up, there was nothing, but it was on my head...

"Ouch...stop and stop..." Qin Lu shouted quickly.

"What's wrong?" Jarvis asked in confusion.

"There is a chuck hair, the armor on the head is still defective, so open it quickly!" Qin Lu said.

"Okay sir!" After Jarvis said, he quickly opened the armor on his head.

The armor on his body was also opened quickly.

Qin Lu fell out of it and then covered his head.

At the head of the armor, a bunch of hair is fluttering in the wind.

"Pull out the model and I'll take a look!" Qin Lu covered his head and grinned.

Qin Lu's body is just strong, but he doesn't feel the pain.

The moment of clamping Qin Lu's hair was pinched off directly.

"Okay sir!"

Simulate the armor on the head, and then Qin Lu starts to check the layout and continues to improve.

"Here, you have a deviation when you do it. You won't calculate the length of my hair?" Qin Lu held a stick and knocked on the head of the armor and said.

"Sir, the drawings you gave are like that!"

Jarvis said aggrievedly.

"Ahem... that... you won't be able to adapt. You are artificial intelligence, not mentally retarded!" Qin Lu coughed and concealed his embarrassment.

"Sir, you say this like an irresponsible scumbag..."

Jarvis said helplessly.

"Stop talking, hurry up, take off your head first, go and change your head, let's try again!" Qin Lu said.

"Okay sir!" Controlling the robotic arm, the armor's head was removed, and Jarvis began to change the size of the armor on his head.

Qin Lu stood in front of the armor again and began to wear this headless armor.

The armor opens.

Qinlu Station went in.

Jarvis detects location.

Close!

When he was shutting down this time, Jarvis was shut down very slowly. He started with his heels, and Jarvis first went from his legs, all the way to his butt, and then to his neck.

"Hiss..." When all the positions were closed, Qin Lu was preparing to move, he suddenly felt a sensation of pain somewhere between his legs.

"Jarvis, open it quickly..."

Fortunately, there is not much problem when opening it.

Qin Lu covered his crotch and almost kicked the test aircraft away with one kick.

"Change again, I almost went to the palace to serve the Empress Dowager when I moved!" Qin Lu said with his teeth.

There are obviously such good physical fitness and strong defense in other places, but the head and crotch are the two heads...

Poor defense.

It's not bad, it's just relative.

The biting force of the armor is very strong when moving, and it almost has the strength of a level three warrior.

Qin Lu, who has good physical fitness, otherwise, if he gave it to an ordinary person, he might have been broken just now.

"oh!"

Jarvis silently pulled the armor away, while Qin Lu once again pulled out the drawings of the armor and modified them.

After a while, the Mark 4 test machine was modified more than ten times, and a month later.

Finally, Tian Qin Lu stood in front of the armor again.

"Okay, Jarvis, this is the last chance. If you mess up, I will change the kernel for you!" Qin Lu said.

"Sir, even if you fail, this is your fault. I won't take it!" Jarvis said speechlessly.

"I said it's your pot, it's your pot!" Qin Lu glared at his eyes, and then stood inside the open armor.

"Buzz!"

After the low mechanical transmission sound disappeared, Qin Lu did not cry out for pain this time.

"Sher!"

"Dong!"

Qin Lu raised his foot, and the teleportation shaft drove his legs to move, and Qin Lu began to move forward.

After taking two steps, Qin Lu began to do various movements.

"Jarvis, test the shell of the armor!" Qin Lu said.

“yesir!”

After Qin Lu finished speaking, he began to lift up and put down the armor.

"Sir, where does it hurt?"

Jarvis asked after finishing the test.

"This time you gave me another reason not to change your kernel. Congratulations!" Qin Lu nodded with satisfaction and continued to move.

Half an hour later, the temporary reactor started to alert, which was an energy alarm when there was still ten percent of the energy left.

"Open it, Jarvis!" Qin Lu walked to the test bench and said.

The armor quickly opens from behind.

The whole process was less than three seconds.

This month, there has been no flowers.

"Sir, the test model is perfect. Can we build the real Mark 4 machine?" Jarvis said.

"It's time to prepare!" Qin Lu nodded.

"By the way, there's something else!"

When Qin Lu walked towards the computer, he suddenly thought of something and said, "Sir, please tell me."

"The armor adds a reserve energy to prevent the reactor from running out of energy, and can also turn on the armor!" Qin Lu said.

"Okay sir!"

This change is very simple, Jarvis can complete it himself.

"Make this project into every armor in the future, unless we can study the nano armor!" Qin Lu said.

"Okay sir!"

...

Next, Jarvis went to build armor with Qin's alloy.

And this process takes a lot of time.

It took almost half a month to build the Mark 3 real machine.

The overall complexity of Mark III is definitely much lower than that of Mark IV.

So, the approximate time given by Jarvis is one month.

And now, it is March 25th, which means that the armor will be released, at least until April 25th!

Qin Lu couldn't help but think that after Mark IV came out, he would have to increase his productivity.

Otherwise, the subsequent armor will be made of harder materials and it will take longer to polish it.
Chapter completed!
