In terms of heavy infantry armor, taking the Republic Defender 2 as an example, the most powerful ones can give full play to the power of the Republic Defender 2 heavy infantry armor is the warrior whose basic ability values are at the fourth level.

If the personal ability exceeds the fourth order, although it can also make the Guardian 2 heavy infantry armor exert the strongest power, but in terms of power, the maximum power output of the Guardian 2 heavy infantry armor can only reach the average value of the fourth-order strength, and the power system of the armor can no longer bless it beyond this average value, and the excessive strength will even cause damage to the armor itself, so for soldiers with too strong personal ability, the Guardian 2 heavy infantry armor can no longer meet their combat needs.

However, due to the more mature armor technology of the Raymond Federation, although the Patriot 2 has shortcomings in terms of defense and other aspects, the power supply can barely meet the needs of the fifth order. And the fifth order is already the recognized upper limit of Type 2 armor in the field of heavy infantry armor. If you want to improve your armor skills, you have to completely break away from the construction mode of Type 2 armor and step into a completely new field.

This led to the creation of Type 3 armor, which has a special design concept compared to Type 2 general armor for ordinary soldiers. This special surname makes the Type 3 armor completely made to match powerful fighters with special abilities, so in addition to the higher-end manufacturing materials and the maximum upper limit of power output, matching a wide variety of special abilities has become the primary criterion for measuring Type 3 armor.

Of the three Type 3 heavy infantry armors captured by Robin, each had a different surname. And these three heavy infantry armors just deduce the three stages of the Raymond Federation in the manufacture of heavy infantry armor.

Among them, the one with the worst surname is undoubtedly the one used by Pete, and this armor is the first step taken by the Raymond Federation into the field of Type 3 armor manufacturing.

From Pete's personal point of view, he didn't have special abilities due to his talent flaws, but his speed and agility were as high as Tier 5. With his basic ability, he is actually still within the tolerance range of the Patriot 2 armor, but because he joined the Twin Star Knights, the most elite of the Raymond Federation, the heavy infantry armor he is equipped with is the first generation of the Federation Type 3 armor that is higher than the Patriot 2 armor.

The Federation's original Type 3 armor can't actually be called a true Type 3 armor, because the original Type 3 armor of this model doesn't have the ability to match special abilities, and at best, it's just an evolution of the Type 2 armor that has made a huge breakthrough in manufacturing materials and power supply.

Since the heavy infantry armor must match the user's personal strength, the higher the ability level, the greater the burden on the heavy infantry armor itself. Type 2 armor made of alloys lacks sufficient toughness and biological sensitivity, so when the user's ability is too high, the armor will be limited by the limitations of the alloy itself and will be damaged.

As for the powertrain, which gives the wearer extra strength, there is also a power cap due to the limitations of the materials used to make it. Therefore, in order to upgrade from Type 2 armor to type 3 armor, the manufacturing materials must be overcome.

Under this premise, biometals were born.

In fact, since the birth of metals, human beings have never stopped researching biometals. In the old era, silver, titanium, niobium, and tantalum were confirmed to be biophilic metals, which could not only replace some physiological tissues, but even have some promoting effects on physiological structures.

However, due to the constraints of conditions, the research on biometals in the old era only stayed at the stage of biophilic metals. The true bio-metal was not unraveled until the new humans discovered a different species from life on Earth in the universe.

These alien species are not intelligent life, but some microorganisms and arthropods in the primitive stage. But as we all know, insects are born chemists, and in the hundreds of millions of years of evolution of insects, chemistry has even become one of their instincts, and in terms of chemistry, these low-end species are even far ahead of humans by centuries.

And the new humans who set foot in the universe discovered another form of metal in the bodies of microorganisms and arthropods, real biological metals.

These biometals are actually microorganisms, but the climate and geological structure that are completely different from those of the Earth make these microorganisms living on alien planets perfectly integrate with the metallic substances. They tend to live in large metal veins, feed on the metallic substances in the veins, and reproduce large populations. Some arthropods with more complex biological structures have found their value, and after these microorganisms are ingested into the body, these ingested microorganisms will naturally parasitize in the carapace of the arthropod as an exoskeleton, and gradually fuse perfectly with the carapace and become a part of the arthropod's body.

The carapace, which is parasitic on a variety of metal microorganisms, is naturally combined into a new alloy that is completely different from the way humans cast it under the chemical action of arthropods. By studying the new alloys extracted from arthropods, human scientists in the new era have discovered that these biometals not only have strong biophilic castes, but even have certain biological characteristics, and far surpass the conventional alloys born by humans through casting technology in terms of hardness and toughness.

As a result, the birth of new biological alloys has finally made a major breakthrough in the research of heavy infantry armor, which has been stagnant due to material problems. Relying on this new bioalloy with biological characteristics, researchers in the Raymond Federation mimicked the physiology of arthropods, mimicking a bio-glue, which was used as an armor liner to fit perfectly into the wearer's skin. Equipping the wearer with heavy infantry armor as if wearing another layer of skin, using this greatly enhanced biological sensitivity, nerve-like energy circuits to construct a more effective power system in the bioglue.

The first Type 3 Heavy Infantry Armor was born, although the first Type 3 Heavy Infantry Armor was only an experimental armor, but in terms of surname, the first Type 3 Heavy Infantry Armor, as a strengthened version of the Type 2 Heavy Infantry Armor, had an absolute overwhelming advantage. Not only has the weight dropped to about half a ton, but it has greatly surpassed the Type 2 heavy infantry armor in terms of defense and biological sensitivity. Moreover, only the first generation of Type 3 heavy infantry armor can theoretically withstand the highest level of ninth-order basic ability.

At a time when the heavy infantry armor technology of the Nine-Star Republic is still in the Type 2 armor stage, the Raymond Federation has been far ahead of the Nine-Star Republic, and through the first generation of Type 3 heavy infantry armor, further, various types of Type 3 heavy infantry armor specially designed to adapt to special abilities have been born one after another.

At present, although the Raymond Federation has only popularized Type 3 heavy infantry armor in the most elite Gemini Knights, it is believed that in the near future, the original Type 3 heavy infantry armor will replace the Patriot 2 heavy infantry armor and become the general-purpose armor of the federal army. And the special Type 3 heavy infantry armor that can adapt to special abilities will soon be popularized in the federal army.

At that time, if a second war breaks out between the Nine-Star Republic and the Raymond Federation, then the Raymond Federation will have an overwhelming advantage over the Nine-Star Republic in the infantry field. There is no doubt that the Nine-Star Republic will lose the war and lose the entire solar system.

It may sound pessimistic, but Robin and the three of them know very well that one day in the future, their pessimistic speculation may be about to come true.

Technological backwardness will make the gap between the combat power of the Nine-Star Republic and the Raymond Federation bigger and bigger, in the nine-star republic where the armor technology is still in the Type 2 stage, the three Type 3 heavy infantry armor captured by Robin and them may be the only three Type 3 heavy infantry armor in the Nine-Star Republic. Robin knew exactly what these three Type 3 heavy infantry armor meant to the Republic. What he couldn't believe was that Brigadier General Archill would have the audacity to give them these three Type 3 heavy infantry armors with different functions and different models with extremely high research value as gifts, which is simply what a madman would do.

Therefore, as soon as he figured out what Brigadier Achill's so-called gift was, Robin secretly contacted Brigadier General Achill, who had returned to the Army Headquarters to report. Thankfully, Brigadier Achill, though daring, is not as brainless as Robin thinks.

During the period when Robin and others stayed in the Pluto Air Force Hospital to recuperate from their injuries, General Aldrich had already used his scientific research team to conduct a thorough analysis and sampling of the three Type 3 heavy infantry armor. Therefore, the data of each group of data for the study of Type 3 heavy infantry armor has long been recorded by the central computer, so these three Type 3 heavy infantry armor are not so important, and they have only become precious samples.

But even so, Brigadier General Achill was extremely bold to give away these three precious samples privately. Therefore, during the period when the TR-735 ship was stationed in the Marseille Space Fortress, Robin did not dare to expose the three treasures. And now, in the vastness of space, after talking about the not-so-optimistic battle situation in the future, Robin felt the need to take out the three treasures and study them. He had a hunch that the Raymond Federation would never give up the war because of a defeat, and he believed that the war would come soon, so the three Type 3 heavy infantry armor would definitely be the key to the survival of the TR-735 in the war.

At this moment, taking advantage of the opportunity for the three of them to talk about the Battle of Pluto, Robin immediately explained this idea to Zoro and Lee.

Before this, Zhuo Luo and Li actually knew what the gift from Commodore Archir was, and now that Robin was planning to take out the three Type 3 heavy infantry armor for testing, they immediately agreed to Robin's proposal and went to the equipment bay of the TR-735 ship with Robin with great interest.
