As soon as Qi Lin focused his attention on the "weapon" option, a confirmation box popped up directly - it seems that in addition to the neural connection system, the retinal projection screen of this ER004 prototype power armor also uses pupil tracking technology.

In other words, Qi Lin does not need to do manual exercises, as long as he uses his eyes, he can complete the control of the power armor operating system.

"Current weapon status - high-power laser cutter: warmed up, ready to turn on at any time; Twin rapid-fire railguns: fully charged, ready to shoot at any time, remaining shells: 691 rounds; Defense and interception system, fire control radar: Active, mini close defense artillery shells remaining: 2350 rounds. ”

"Yanqiu, I need a shooting target!" Qi Lin manipulated the ER004 prototype model to the open space outside and said to Cheng Yanqiu.

"It has been prepared for a long time - a hundred meters forward, there is a newly dug tunnel, four meters deep and wide, two hundred meters long, and at the end of the tunnel there is a target stacked with composite armor with a thickness of four hundred millimeters, and the filling inside the target is high-strength quick-drying cement."

Qi Lin kicked his legs, and the jets on his legs ignited instantly, and a powerful thrust directly made the entire power armor fly diagonally into the air at a height of twenty meters.

This is Qi Lin's first time piloting a power armor with flight ability, and the difficulty of operating the ER004 flight system is much simpler than Qi Lin's expectations, Qi Lin only needs to control the direction and speed, and the rest is all handed over to the power armor's intelligent brain operating system.

"It's just a fool's errand...... Why did Lu Wei still say that he needed enough strength to give full play to the extreme combat power of this power armor? ”

With a hint of puzzlement, Qi Lin controlled the power armor to land steadily at the end of the tunnel, aiming the twin rapid-fire railguns at the target like a turtle shell two hundred meters away.

The aiming system of the power armor is also very user-friendly, it will judge and lock on to the target according to the focus of the operator's line of sight, and the operator only needs to confirm and order the fire.

"Shoot!"

With the buzzing noise of the charging coil, a bright yellow streamer shot directly at the target not far away, and a huge explosion sounded immediately.

"A total of 14 shells were fired, and the degree of target damage: 98%."

When the smoke from the explosion cleared, the original target was gone, leaving only fragments of torn armor plates, and there were obvious traces of melting at the edges of these fragments.

"The firing time is 1.5 seconds, and excluding the 0.5 second pre-charge time, the rapid-fire railgun has a rate of fire of exactly 14 rounds per second." Cheng Yanqiu drove the vehicle to the edge of the tunnel and told Qi Lin the results of the test he had just found.

"Well, the rate of fire is fast, and it only needs to be charged before the shooting starts, the power of a single shot is a little weaker than that of a single railgun, but it is not too weak, but the interval between each shot is shorter than the three-shot mode of the individual railgun, and the lethality of this rapid-fire railgun is enough to kill the tower-level parasite in an instant." Looking at the mess at the end of the tunnel, Qi Lin nodded slightly.

"There is no need to test the laser power, according to the rated power marked on the fire control system, at least it is no problem to cut the armor of the main battle tank as tofu, but the energy consumption is too great."

"Well, the next test to be done is the active defense system, and I will have people shoot at you at the same time with thirty RPG bazookas and fifteen Stinger anti-aircraft missiles at a distance of two hundred meters-"

Before Cheng Yanqiu's words were finished, a piercing alarm suddenly sounded over the Herrens defense line - this alarm meant that more than 50,000 Kuroshio of more than 50,000 people entered the three-kilometer range of the city wall, and the entire defense line instantly entered a combat state.

"It seems that our actual combat test is going to be advanced, but what I wonder is that according to the speed of ordinary parasites, those guys should not come back so soon, and as for the third wave of the Black Tide, it is even more impossible."

"I don't know, let's take a look, no matter what, this alert won't lie."

……

Qi Lin and Cheng Yanqiu soon climbed the wall of Herens again, only to see a large area of parasites in the distance that was pressed by black pressure approaching the wall of Herens, which was the wave of black tide that had been led away by Qi Lin before.

This time, anyone with a discerning eye can feel that the resurgence of the Kuroshio is moving much faster, and if you have a high-powered scope or telescope, you can clearly see that the way those ordinary parasites move has changed from staggering forward to running in small steps.

Although the running movements were very clumsy, and the parasite would be tripped and fell to the ground from time to time, the movement speed of this wave of the Kuroshio was several times faster than before.

"I see...... Are there any new changes in these guys? Qi Lin put down his binoculars and muttered, "However, how long has it been, and besides, there are no stimuli that can cause such a level of abnormality?" ”

"No, there are irritations, have you forgotten, we just captured the king-level parasitic worms that control them, and for the sake of this king-level parasitic worm, these parasites are chasing you in a huge circle in the wilderness." Cheng Yanqiu pondered for a while and spoke.

"You mean, the king-level parasitic worm caused this mutation? However, now that the king-level parasitic worms have been handed over to Lu Wei, perhaps, they are no longer in the Hellens defense line. ”

"I'm just guessing at that, but do you think that these parasites who have suddenly learned to run have a bit of a 'dog jumping off the wall'?"

"Sort of." Qi Lin nodded, "I'll go down and meet these guys first, and by the way, I'll test them, in addition to running away, what new changes do they have." ”

……

Because of Lu Wei's commission, Qi Lin's application for battle was quickly approved by the command - Qi Lin could leave the city wall alone and attack the invading parasites, and at the critical moment, the artillery of the Hellens Line would also give him corresponding support.

Manipulating the tall ER004 power armor, Qi Lin jumped directly from the thirty-meter-high city wall, and just as the power armor was about to touch the ground, the jet instantly spewed out a half-meter-long cyan blue flame, pushing the power armor into the air again.

After adjusting the angle slightly, Qi Lin directly rushed towards the more than 100,000 parasites in front of him, and at the same time, the twin-mounted rapid-fire railgun had already locked on the dozens of tower-level parasites that were the most conspicuous in the Black Tide.

"Shoot!!"
