Chapter 4: Suspected plug-in

　　 Rong elephant knelt and raised his spear, his hands were so steady that he didn't even seem to tremble. Then, facing the alienated beast that jumped up all at once, he calmly and simply pressed the trigger...
　　 "Suddenly..."
A series of muffled noises came from his muzzle. It was the scream of the bullet tearing the air after the muzzle muffling process. The GR-100 fired at the alienated beast at a rate of 4.5 bullets per second. Dumping the metal warhead in the magazine.
　　 A warhead with an attack coefficient of 1.2 cannot penetrate the scales of the alienated beast, but the cumulative impact of the warheads is enough to hit the alienated beast's body to a halt.
　　 Then the Rong Xiang squeezed the trigger and fired continuously for ten seconds without interruption, and all the bullets in the magazine were poured out all at once. And the body of the alienated beast was finally smashed into a sieve within these ten seconds... Its body's defensive coefficient of its scales is only 1.7, and if it is attacked twice in a short time in the same area, it will be defeated. What's more, these ten seconds of continuous shooting?
　　 Seeing the body of the alienated beast fell to the ground, Rong Xiang did not have any relaxed expression on his face. Because the moment the alienation beast fell to the ground, he saw the appearance of alienation beasts from the various vents on the ceiling of the restaurant!
　　 swiftly made a back-rolling, and while tumbling, had already unloaded the empty magazine, and then took out another full magazine and inserted it into the buttstock. Then the tumbling ended, he had already passed through the damaged doorway of the cafeteria to the aisle outside, and still maintained the standard combat posture of kneeling on one knee and aiming a gun.
　　 And at this moment, an alienated beast has already rushed out, reaching the broken door opening of the canteen’s entrance, and is about to rush out...
　　 "Suddenly!"
　　 Three bullets hit the alienated beast's head with almost no gap, and it was still on the same spot on its head, the error interval was even within two centimeters!
　　 A blood hole appeared on the head of the alienated beast, and then it fell to the ground. Obviously, even if this alienated beast grows strangely, its head is still the center that controls the body and is also a key part.
But the crisis of Rongxiang only began, because the alienated beast fell and two more alienated beasts appeared in his line of sight one after the other...At this time, his gun hands were still steadily trembling. But his attention has been concentrated as never before, and he continuously pulls the trigger with a crazy and terrifying mentality like dancing on the tip of a knife...
　　 "Suddenly!"
　　 "Suddenly!"
　　 Two strings of bullets accurately hit the heads of the two alienated beasts, and more importantly, they all hit almost one point!
　　 This is the reason why Rong Xiang previously squeezed the trigger at the first alienated beast and emptied a magazine. He was looking for the gun's muzzle bounce pattern! Even if it is a Gauss rifle, there is still a certain amount of recoil. He used his body muscles to memorize this recoil before, and only then did he have the amazing operation of killing two alienated beasts with a single shot in a short time.
　　Originally, no matter how good GR-100 performance is, and his gun technology is outstanding, it will take a process from unfamiliar to familiar for new guns to reach the level of fingering. But when he framed his shooting targets in a relatively narrow doorway, his shooting skills could completely make up for this strangeness.
　　 The alienated beasts behind the gate are still rushing out, but at this time they have to move away the corpses of their ‘companion’ before they face the elephant. And their method is very rude, it turned out to be to shred their similar corpses!
　　 But this is tantamount to serving as the perfect target for Rong Xiang. He gave all the alienated beasts three warheads that appeared in front of him, but it was enough to kill any alienated beast. There are a total of 45 warheads in his magazine, and based on three exploding an alien beast, he can kill 15 alien beasts in total. But unfortunately, there were not so many alienated beasts in the vents in the canteen. In fact, after the ninth alienated beast was killed by the Rong Elephant, there was no trace of any alienated beast in the cave.
　　 "Hoo~"
　　 The breath he held was only now exhaled, and his nervous spirit was slightly released at this moment. Then his heart beats rapidly, which is a normal phenomenon after short-term holding of breath and adrenaline secretion.
　　 But he hasn't let down his vigilance. The mercenary career in his previous life made him understand that as long as there is no moment of absolute safety on the battlefield. It was just when he was about to leave this place where he had only experienced a big battle and returned to his safe house to replan. However, his eardrums suddenly vibrated and heard the sound of his built-in auxiliary device...
　　 "It was detected that the host's mental power exceeded the peak..."
　　 "The host's mental power exceeds the critical point and meets the criteria for the activation of Protocol No. 57. Will Protocol No. 57 be activated?"
　　 "What is that?" Rong Xiang was full of doubts, but his professionalism made him know that this time is definitely not a time to be distracted. So forcibly suppressing the doubts in his heart still decided to implement his previous plan to retreat.
　　 But just when he took a short break to change the magazine and then turned his head and walked out two steps...
　　 "The host failed to make a decision within three seconds. According to the implementation rules of the 57th protocol, the host starts the 57th protocol by default..."
　　 "What?!" Rong Xiang was a little annoyed, because he hated things that were beyond his control when he was performing combat missions.
　　 "Protocol No. 57 was activated, and the auxiliary instrument completed the system update and was renamed the Super Soldier auxiliary system."
　　 "Ding! It was detected that the host body has low levels of various trace elements and needs to be supplemented as soon as possible."
　　 "Ding! A large amount of biological protein has been detected within ten meters of the host. Will it be collected and purified?"
　　 "Ding! Trace zero elements are detected within ten meters of the host. Do you want to extract?"
　　 A series of system prompts almost stunned Rong Xiang, which made him feel like he had won a big prize... His first reaction was, could it be that his ‘Passenger Benefit’ has finally arrived, right? However, after I read these system texts directly projected on my retina, I realized that this should be the function that the auxiliary instrument originally has, and it can only be turned on after the host meets certain conditions.
"Yes Yes Yes Yes!"
　　 The Rong Elephant also wanted to go horizontally, so he simply chose to confirm all of them. He wanted to see what kind of changes the auxiliary device that suddenly appeared moth would bring to him. At the same time, most of his attention was focused on the vigilance, he didn't want to relax his vigilance because of these emergencies.
And under his alert, he found that the metal stripes on the black rock uniform on his body exuded a gamma-ray-like icy blue beam... These beams shone on the body and blood of the alienated beast, unexpectedly. It quickly decomposes them into many tiny particles!
　　 At the same time, he also noticed that the energy that was almost full in his combat uniform began to decay. Obviously, the current ‘Super Soldier Assist System’ still manipulates the Black Rock combat uniform to complete the system prompts and collect instructions. In other words, this system update is really a product of human science and technology of this era, and it is not the ‘golden finger’ that Rong Xiang had originally longed for.
