"Hi Jerry, your gear is ready, do you want to check it out!" Captain America pushed open the door of the library and said to Yan Xu, who was reading a book.

"I thought I would have to wait a little longer, but I didn't expect it to be done, and the efficiency is really fast." Yan Xu put away the physics book he was reading, stood up and said to Captain America.

"Of course, S.H.I.E.L.D. is very efficient, and it hasn't let us down yet, because we have the right to complain." Captain America said with a wink at Yan Xu.

"What are you waiting for, I can't wait to see it."

"Trust me, you'll love it, it's beautiful."

The distance between the equipment department and the library is not close, after all, some equipment is still relatively dangerous, so the location is relatively remote, of course, the protection force is not weak, and it can rank among the top few in S.H.I.E.L.D.

Walking on the road, Yan Xu has a lot of time to imagine what his new equipment looks like, and whether some problems have been solved, after all, the side effects of overheating the body caused by excessive use of ripples are still unavoidable, even Professor Bolden has no way, after all, the higher the power of electromagnetic waves, the higher the heat generated, not to mention that Yan Xu is not a machine, but a human body full of more unsolved mysteries, and the threshold between physics and biology is so easy to break, so for the time being, I can only find a way from foreign objects, However, Professor Bolden has invited an authoritative figure in the biological field to practice his hands to solve some of the problems that Yan Xu is currently encountering.

The driving knight used by Yan Xu before is a very good idea, and S.H.I.E.L.D. has upgraded and improved it according to the previous wreckage, and the most direct thing is to replace the shell with an experimental titanium alloy.

Many people think that titanium alloy is an extremely hard metal, in fact, there are many alloys that are harder than titanium alloy, but the comprehensive performance of titanium alloy is the best, low density, high hardness, corrosion resistance, high temperature resistance, and one of the best metals in aviation, so Yan Xu's new equipment still uses titanium alloy.

However, this time it is not a civilian titanium alloy that is only harder than steel, or even a military titanium alloy, but an experimental titanium alloy that is still in the laboratory and cannot be mass-produced.

There are many technologies and materials beyond ordinary people's imagination in the laboratories of various countries, but these things cannot be mass-produced at all, so they do not have much practical significance, after all, even if an Iron Man is assembled, even if the Iron Man in the movie can only be a superhero, he is not much stronger than ordinary people in the face of national-level collisions, if it is not for his identity as a rich man, it is not as difficult to deal with him as imagined.

The new titanium alloy match was obtained from Iron Man, the other party has the best titanium alloy formula currently known, and only one centimeter of thickness is needed to resist the attack of most modern weapons, even if the thickness of the steel suit has been weakened, it can still easily resist the main battle tank gun that does not use armor-piercing shells, and it is simply an invincible shield in military terms.

This recipe is the product of Iron Man's compromise, which is naturally a weakened version, but it still has far more performance than all titanium alloys today, but it has not yet solved the problem of mass production, and only a small amount of production is used for testing.

Because a small amount of gold is added to the new titanium alloy formula, it is named gold titanium alloy, and the natural metallic color is also full of nouveau riche feeling golden, which makes Yan Xu at first sight have the feeling of seeing the gold of a copycat tycoon.

"Although the color is a bit special, it hasn't been coated yet, so you can choose a color later, and let them introduce you to this armor first." Seeing Yan Xu's face, Captain America couldn't help but smile and patted him on the shoulder and said, obviously he was also shocked by this color.

"Mr. Paladin, this Golden Knight has been perfected from your original driving knight, replacing the shell from ordinary titanium alloy to better performing gold titanium alloy, the armor thickness is between 0.3 and 0.8 millimeters, and the strongest breastplate can even withstand direct hits from individual bazookas without being penetrated." The staff member proudly patted the Golden Knight's very special chicken-breast-shaped one-piece armor.

The costumes of most heroes are tight-fitting shapes that are eager to tilt the little brother to that side, and the chest is the standard two pectoralis major muscles, but this golden knight is the chicken breast type of traditional knight armor, and it is also one-piece, with stronger defense, even if it is deformed by a heavy blow, it will not squeeze the chest cavity, resulting in loss of combat effectiveness.

Although the shape is a little worse, the shape of the chicken breast allows a buffer space between the armor and the body, which will not directly cause damage to the body, and has more practical combat value. These S.H.I.E.L.D. researchers are not stylists, many of them are military researchers, and everything starts from actual combat, and then comfort and appearance, so it is impossible for them to reduce practicality and adopt more beautiful shapes.

"The lining was not installed according to your requirements, and we originally prepared a new type of polymer that can absorb 80 percent of the impact force, and the impact ceiling reaches one ton, but unfortunately you don't need it." It's a pity that the staff didn't continue to improve the Golden Knight, after all, although the inner lining can absorb the impact, it will also affect Yan Xu's ripple emanation, and finally discarded this part, which causes this Golden Knight to only be Yan Xu's exclusive equipment, unless it continues to be perfected, it can't be popularized.

"The auxiliary power unit is a half-finished product specially designed by Professor Bolden, and he said that the other half needs to be filled in by you, you can try it out, and if there is a problem we will modify it."

"Because there is no need for lining, and there is a semi-finished power plant, the Golden Knight has a lot of leeway, and we have installed some auxiliary equipment, which you can learn from the manual."

"The external equipment is mainly round shields, one-handed swords, spears and other traditional cold weapons, among which the round shield is according to your requirements, from the metal round shield you originally equipped to extract a special magical metal added to the gold titanium alloy and cast, after testing, the defense is second only to the captain's vibranium shield, but unfortunately this metal is not a product of the earth, and it is also composed of a single element, and there is no possibility of imitation at all." Speaking of this, the staff member showed a very regretful expression.

He was talking about Mithril, this otherworldly metal has the property of fusing any substance, and is not rejected by the body's immune system, the original weakened version of the gold-titanium alloy has even surpassed the momentum of the original after fusing this metal, and the value is so high that it is simply indescribable, and it can even be directly used on the armor of space warships.

It's a pity that after research, this metal is an unprecedented single element composition, the structure is stable, and this element is not on the earth at all, so that a group of researchers are about to go crazy, obviously a huge treasure, but there is only one gold coin, this contrast can make people vomit blood.

S.H.I.E.L.D., knowing about the demonic invasion and the drop of equipment, believes that this magical metal comes from another world and has no possibility of mass production, unless they can break into the abyss to colonize.

In fact, this metal is the same as Captain America's vibranium shield, without vibranium, a magical metal from the universe, they can't reproduce it even if they have the shield formula, so they didn't intercept it, and all of it was used on Yan Xu's shield to create a work whose defensive power is second only to Captain's vibranium shield.

"Finally, the cooling device placed inside, originally we planned to use a tightsuit containing a special coolant, but it was rejected for the same reason as the lining, and then we used an air-cooled device, which sprayed compressed cold air from a fixed nozzle to form a cold air circulation inside the armor, although it will cause a large air leakage sound, but in the assumption, your ability will not be overloaded under normal circumstances, and the situation that can cause overload will definitely face a fierce battle, so some sounds will not have an additional impact on stealth and concealment."

Yan Xu nodded again and again, he really deserves to be a professional, some details are very important, even Yan Xu can't find anything wrong, of course, this is not to say that this golden knight has no defects, but it is relatively more in line with Yan Xu's ability.

"Do you want to try the equipment?" Captain America said to Yan Xu eagerly, obviously he had some itchy hands.

"Come on, then!" Yan Xu did not refuse, took off the round shield on the golden knight, put it on his hand and said.

The staff next to him not only did not stop but quickly made room for the two, obviously very interested in the two fighting, after all, one is the famous American team, the other is the paladin who has also reached the peak of mankind, and the two superheroes who are also good at using shields can not be seen at any time.

Captain America took off the shield behind his back and put it on his hand, unable to hold back his excitement.

He obtained the ability of Captain America in the early days, and it has been a long time, but he has been cooperating with research in a secret laboratory to see if he can copy the super soldier serum from his body, but unfortunately it has not been fruitful.

But he didn't waste time, where there were special personnel responsible for training him in various combat skills and command skills, so that he mastered the abilities of Captain America in a very short time, and even performed several tasks perfectly, but he never fought with someone who also used a shield.

The opponent has the same peak physical strength as him, extraordinary combat skills, and weapons are shields, such an opponent he may not be able to meet in his life, of course, he can't miss it.

The two of them started and sprinted at the same time, also holding their shields in front of them, colliding together like two out-of-control cars.

But the strange thing is that with such a violent impact, it stands to reason that either one person was knocked away, or both people flew upside down, but what is surprising is that the two people completely ignored physics and froze in place, and even their movements did not change, and what was even more strange was that there was no sound of collision, you must know that they were using metal shields, and they didn't even make a sound.
