After sending Dr. William away, Qi Jianfei immediately took out the giant armor and put it in the most conspicuous position in the laboratory, whether it can attract Tony Stark's attention depends on it.

Then he was not idle, but took out the pumpkin bomb and dismantled it, it happened that the equipment in this laboratory was very advanced, and the process of dismantling the pumpkin bomb was surprisingly smooth.

Sure enough, as Qin Yu said, after dismantling a pumpkin bomb, he suddenly had a lot more understanding of the structure of the pumpkin bomb, and took out a pen and paper to draw a drawing of the internal structure.

When the second one was dismantled, the detonation method of the pumpkin bomb, the shell structure and other details were already clear, and only four pumpkin bombs were dismantled, and the drawings were basically completed, and when he was halfway through the fifth one, the sound of the system immediately sounded in his ears.

[System Hint: You have successfully obtained the Pumpkin Bomb crafting process by dismantling it, and the crafting process has been recorded in your skill list.] 】

It worked.

Qi Jianfei was a little excited, he calculated the materials, the cost of the pumpkin bomb is not expensive, the cost of a pumpkin bomb is about five hundred dollars, which is a little more expensive than a grenade, but it is already the price of cabbage for a high-tech weapon, and Qi Jianfei buys materials cheaply, and the cost can be further compressed, it is estimated that it will not cost more than 300 US dollars.

Qi Jianfei went directly to the logistics department to buy a batch of materials at cost price, plus the free materials already in the laboratory, and used the existing equipment in the laboratory to manufacture them, and it took more than an hour to make twenty in one go, and then he used up the materials almost before stopping, and then he used his mechanical engineering to convert the grenade launcher into a pumpkin bomb launcher.

After the modification, he did not stop, after a series of manufacturing and modification, he successfully upgraded the mechanical engineering to LV2, plus his creative talent has reached LV5, and found some places where the giant armor can be upgraded, so he happily continued to transform.

Qi Jianfei was busy renovating, but a voice suddenly sounded behind him.

"Did you make this thing?"

As soon as Qi Jianfei turned around, he was suddenly startled, a man with an anchor beard was holding his shoulders and looking at his giant armor with interest, the light in his eyes seemed to be that the little boy had seen some kind of novel toy, this person's appearance was so familiar that Qi Jianfei recognized it at a glance.

Damn, it's Tony Stark! At this time, the other party was looking at his giant armor with interest.

"Well, that's right, I mean, I made it, and I call it Giant Armor Type 1."

Qi Jianfei's tone stumbled a little and said, no way, this is Iron Man, exactly the same Iron Man, appearing alive in front of him, even if he knew that it was just a game, it still made him a little involuntarily excited, especially when the other party was completely a living person, almost made him forget that this was a game, as if he had really traveled to the world of the Marvel Universe.

Tony Stark ignored his agitation and walked over to himself, picked up a wrench and gently tapped the shell, checking the structure of the giant's armor.

"The mechanical structure is simple and practical, what energy does it use?"

"V15 model military high-voltage battery." Qi Jianfei hurriedly replied.

Stark pursed his lips and seemed disdainful, "I'm afraid this power source can't make it run for a long time, the power is too poor." ”

He knocked on the shell of the giant's armor, and after listening to the voice, he made a judgment, "Ordinary armor steel, and it is very thin, it will not exceed 5 mm, such a shell is too fragile, it should be redesigned with a super-strong alloy, because of the battery, it can't be made too thick, and if it is on the battlefield, the survivability will be very limited."

The hydraulic engine power is too low, and it is estimated that it can only jump two or three meters high at most, and if you use our latest model of Stark Industries' electronic pulse engine, the jumping ability can be increased by at least 50%.

The weapon system was so crude, it didn't seem to even have a fire control system installed, and I was very skeptical that it would be able to hit a target fifty yards away.

It didn't take long for Stark to pick out a dozen faults in the giant's armor, as if this thing was useless at all, but in the end, Stark still nodded. "Although it is a relatively crude product on the whole, it still has a certain practicality, unlike those broken things that can only stay on the drawings and in the laboratory, which are well done."

Qi Jianfei listened to it and said in his heart, "Are you praising me or hurting me", but he was not unconvinced, he was Iron Man, and it was an honor to be able to give him a few words.

However, he still defended, "Strictly speaking, it is only a half-finished product, I made it in the military laboratory, and it only took a few hours in total, and then because of an accident, I left there, and I brought this thing out, and I have been trying to find a way to improve the previous design, but unfortunately I have limited resources and no suitable equipment, and many things can only stay on paper."

One of the most limiting things for me is the power source of the armor, as you must know, you can't do anything without energy, in fact, I have a bold plan, I know that Stark Industries' Ark Reactor can produce amazing energy, if you can shrink the Ark Reactor and install it on this mecha, then everything will not be a problem, whether it is armor, engines, weapon systems, you can play to your heart's content. ”

Qi Jianfei said what Qin Yu had taught him before.

"Do you want to shrink the Ark Reactor and put it on? A very bold idea. Tony Stark also seemed to be touched by Qi Jianfei's words, with a thoughtful expression on his face, thinking about the feasibility of it, whether the Ark Reactor could be done very small.

Qi Jianfei watched from the side, he didn't dare to breathe, for a long time-

"I have to say, your plan is very bold, but it is not impossible to succeed, are you a new scientist?"

"Uh, yes, my name is Qi Stark Jianfei, a mechanical engineering expert who has just been hired as a laboratory supervisor."

"Qi Stark Jianfei? It's a strange name, I have to say that William finally did something serious this time, maybe one day we can discuss this aspect together. ”

"Of course, I'd love to." Qi Jianfei hurriedly agreed.

At this time, the sound of the system prompt sounded again.

System Hint: You've managed to get Tony Stark's attention, the character has appeared on your social list, and you can interact with it to increase or decrease the character's favorability.

Finally it worked.

Qi Jianfei was excited in his heart, opened the social list, and sure enough, Tony Stark's avatar appeared in his social relationship list.
