Like a bolt of lightning tearing through space, the golden streamer reached the tower-level parasites locked by the rapid-fire railcannons in an instant, and then, the rapid-fire cannonballs wrapped in huge kinetic energy tore everything they came into contact with to shreds.

In order to increase the lethality of rapid-fire shells and their ability to destroy armor, an additional layer of metal mask with a low melting point is added to the front end of the warhead, and in the process of high-speed flight of the warhead, the metal mask and the air are rubbed at high speed, and the high temperature generated will melt it, and then form something called "metal jet".

The so-called metal jet is a liquid metal stream in a high-speed state of motion, the speed of the metal jet is very fast, it can reach thousands of meters per second, when this metal jet hits the target head-on, it can instantly cause a pressure of one million atmospheres.

The metal jet was originally a technology applied to armor-piercing shells against armored targets such as tanks, but due to the extremely short charging time of rapid-fire coil weapons, the kinetic energy attached to the warhead was much weaker than that of single-shot coil weapons, so this technology was improved and used on rapid-fire electromagnetic bombs.

The golden streamer dragged behind the rapid-fire electromagnetic projectile is the afterimage left by the molten metal jet in the human retina.

After a strafing shot, there was no longer a complete tower-level parasite within five hundred meters of Qi Lin, and Qi Lin landed on the ground and pulled out the only melee weapon equipped with the ER004 prototype power armor.

This is a high-frequency cutting blade with a length of nearly two meters, when Qi Lin and Arthur Li dueled, Arthur Li used this high-tech melee weapon that sharpens iron like clay, but this high-frequency cutting blade that can be regarded as a giant sword for humans is held in the hands of ER004, it is at best a flexible short knife.

Holding the high-frequency cutting blade in the right hand of the power armor, the ER004 prototype squatted down under Qi Lin's control, his back was slightly arched, and his free left hand was propped up on the ground, and the whole posture was like the squatting start of a sprinter at the sports meeting-

"Power furnace output - eighty-five percent!"

With Qi Lin's command, only a series of bursting roars were heard from the power furnace, and the eight jets shot out cyan flames several meters long backwards in unison, and the entire power armor was like a sharp sword tearing through the wilderness, crashing headlong into the black tide!

The high-frequency cutting blade that was upside down in the palm of his hand instantly popped out, and the waving mechanical arm continued to harvest the life of the parasite.

Although the ER004 prototype is in a state of high-speed movement, in the eyes of Qi Lin, who has turned on the Eagle Eye skill, the speed of ER004 is about the same as the speed of an ordinary person's jogging, he can easily and accurately use the high-frequency cutting blade to pierce the head of each parasite that passes by, and then use the high-frequency vibrating particles on the blade to directly shock the parasitic worms in the parasite's brain into powder.

Qi Lin alone entered the core of the Black Tide, and at this time, the exterior armor of the ER004 prototype was already covered with all kinds of broken corpses, intestines still dripping with pus and filth, and many alienated internal organs, and the entire power armor looked as if it had been soaked in the blood pool of hell for a long time before climbing on.

"That's ...... so"

Qi Lin, who was sitting in the cockpit, found that no matter how fast his reaction was, the ER004 prototype controlled by nerve articulation technology could always keep up with his movements, and with the help of the jet, Qi Lin could even break the sound barrier with one punch, although this kind of operation was also very powerful for the loss of the power armor itself, but in close combat, a supersonic punch could almost lay the victory in an instant.

"The performance of long-range weapons, with the operation of the fire control system, has been developed almost to the limit...... So what Lu Wei said, the upper limit of power armor should refer to mobility and melee ability......"

Although Qi Lin didn't understand that the weapons and equipment had developed to this point, why the Lu family and the Tianzhi Foundation still had to work melee combat when developing a new type of power armor, but I have to say that the ER004 prototype model is indeed the most suitable for melee combat among the power armor that Qi Lin has driven.

To be precise, ER004 can't be counted as power armor at all, it should be a weapon that is somewhere between a tactical mech of power mech.

Power Mecha and Tactical Mecha, it seems that the difference is only in size, but in fact, this is developed from two different equipment.

Power armor is derived from the mechanical exoskeleton that enhances the combat ability of individual soldiers, and is designed to maximize the combat ability of infantry, while tactical mecha is developed from heavy equipment such as tanks, in order to solve the problem that ordinary combat vehicles cannot cope with complex terrain.

If ordinary power armor is compared to a bolt rifle and tactical mechs are compared to heavy machine guns, then the armor of the ER series is a submachine gun in between.

With the exception of Dongying, other countries have not invested too many resources in tactical mechs, and tall mechs that are more than five meters tall can easily become eye-catching targets, and it is extremely difficult to balance the best balance between armor thickness and mobility.

Until the end of World War III, the largest application market for mecha was still in the private sector, used for work such as handling and unloading goods, building construction, ore mining and so on.

There are only a few famous tactical mechas, among which the largest output is the "Ghost King Mecha" of Yamato Heavy Industries.

Huaxia itself did not have the idea of developing tactical mechas, and those bigwigs in the military agreed that the humanoid tactical mechas, which shine in various science fiction works, are not as good as tanks and self-propelled guns in reality.

Unless, humans can acquire the "GN particles", "PS armor", "solar furnaces" and other black technologies in GUNDAM......

Otherwise, vigorously developing humanoid tactical mecha is a completely thankless task, and with this energy and military spending, it is better to develop the next generation of new warships and long-range missiles.

It's just that the emergence of the ER series power armor may be a different way - miniaturizing the mecha and using it as an individual elite unit is also a feasible tactic -

Artillery and air force cover strikes, followed by tanks, power armor mixed armored units frontal advance, infantry closely followed armored forces, as for the ER series of elite power armor, it is used as a mobile tactical unit to contain enemy forces, flank attacks, and sneak attacks around the rear, and when necessary, it is also used to perform "decapitation tactics"!
