Xiang Yang was the first to walk to the door. She held the notebook in her hand and checked it several times before fumbling to open the lid of the combination lock and entering the password.
[Beep. Password correct. Please perform fingerprint verification and iris authentication.]
The stiff mechanical voice suddenly sounded.
The corners of Lu Ren's mouth could not help but twitch. "Then how are you going to get in? I doubt you have the fingerprint verification and iris authentication for this research center, right?"
Xiang Yang ignored Lu Ren's mockery and flipped to the second page of the notebook. After reading it seriously for a few minutes, she then called up the input box on the touch pad and entered nearly a hundred characters.
[Beep. Super administrator activated. Connected to the main control center… Center's authentication completed. Special authorization unlocked. It's a pleasure to see you again, Super Commander! Please re-authenticate the fingerprint information and the iris patterns here.]
After Xiang Yang had confirmed everything, she turned to Lu Ren and said, "You authenticate too."
Lu Ren was stunned. "Me too?"
Xiang Yang said seriously, "You're stronger than me. If I accidentally die, you still have a chance to escape. Without authorization, you won't be able to move an inch inside."
Lu Ren's heart skipped a beat. He could not help but look at Xiang Yang in surprise. "What the hell is this? Has she been conquered by my handsome face?"
This gaze made Xiang Yang's face turn red. She said shyly, "What are you looking at?"
"Should I say this or not? You do look pretty."
Xiang Yang's face turned even redder. She stammered, "Uncle, don't you think the age gap between us is too great?"
Lu Ren shook his head slightly and walked forward. "What do you need me to do?"
"It's like this…"
Following Xiang Yang's instructions, Lu Ren registered his fingerprint and iris, and the alloy door opened slowly with a grinding sound.
Lu Ren's pupils constricted, and the longsword in his hand suddenly stabbed into the gap in the alloy door that had just been opened.
Chi!
The sound of flesh being sliced could be heard suddenly, and then he saw a sharp, thick palm covered in black scales grabbing at him. The longsword cut off half of the other party's palm.
After automatically filtering the System notifications in his mind, Lu Ren leaned back and swung the sword in his left hand heavily, hitting the other party's sharp fingers covered with scales.
Clang!
The sound of metal clashing suddenly sounded. The webbing between the thumb and forefinger of Lu Ren's left hand turned numb from the impact. However, apart from a series of sparks, it did not break through its defense at all.
Lu Ren had no choice but to pull out his sword and retreat quickly. However, Xiang Yang, who was at the side, did not retreat at all when she saw this. She pulled out the dagger strapped to the side of her thigh and slashed down.
In the end, this made Lu Ren open his eyes wide. The other party's dagger did not face any obstruction upon hitting the arm covered in scale armor. It sliced off the entire arm like cutting tofu. He could even sense the sharpness from his direction.
It was like something written in martial arts novels.
"What kind of dagger is this?"
"Ultra-High Frequency Cutting Blade. It can cut through any currently known alloy through high-frequency vibration."
Xiang Yang only explained it in a sentence.
Hearing this, Lu Ren's heart itched. Damn, wouldn't he be invincible if he could obtain this?!
Lu Ren looked at the broken arm, which was still flailing on the ground. Then, he looked at the alloy door which had opened and the figure of the monster behind it.
It was at least 2.5 to 2.6 meters tall, and its entire body was covered in scales. Its facial features were protruding, and its mouth was full of fangs. However, Lu Ren could see clearly that it was only covered in most parts. There were still many parts that revealed the patterns of black skin. However, because the colors were similar, it was not obvious.
The moment the alloy door opened, the monster roared and leaned over, trying to rush into the corridor.
There was no way back. If the big fellow were to really charge into the corridor, there would not be much space to maneuver.
Fortunately, Lu Ren did not retreat but advanced instead. He turned his body to the side to avoid the sharp claws that were sweeping over. Then, as he relied on the momentum to kneel down and slid out from under the monster, he stabbed the two swords in his hands hard into the unprotected lower part of the other party's body, all the way till the end of the hilt. Lu Ren could even vaguely sense the other party's pair of bells shaking above his head. He could not help but feel a chill.
In the next moment, a shrill roar that seemed to shake the entire base sounded from the monster's mouth.
Even Xiang Yang tensed up when she saw this scene. A sense of testical pain suddenly surged and lingered in her heart.
It was very sick and terrifying!
She did not know why she suddenly wanted to walk with her butt clamped between her legs.
Lu Ren, who had rolled continuously for five meters, stabilized his body and watched as the contaminated creature held its lower body and bent down kneeling on both knees. It did not move for a long time.
[Ding… You have wielded the two swords and suddenly made one clever move and stabbed the vital points of the Gray-Scale Demon, producing a critical strike bonus. As a result, you have gained some insights. Your basic swordsmanship proficiency has increased by 100.]
[Ding… Due to your quick thinking, your agility has exceeded the expectations of the Gray-Scale Demon and caused great harm to it. Your Agility Proficiency Level has increased by 50.]
The corners of Lu Ren's mouth twitched. As his proficiency increased, the twin swords became more smooth and skillful in his hands.
This would greatly increase his ability to survive.
He stood up and turned around. He narrowed his eyes and thrust his sword out. It slashed accurately at the area on the neck of the Gray-Scale Demon which had not been covered in scales. It went right into the flesh and cut into the cervical bone before stopping.
Tsk, if the sword in his hand was as sharp as the dagger in Xiang Yang's hand, he would have cut off this huge head long ago.
As his thoughts raced, Lu Ren's left hand did not stop. He did the same thing and slashed down from the left into the neck of the Gray-Scale Demon, stopping only when it reached the bone.
With a slight flick of his wrist, he suddenly let go of the long swords in both hands. The two strange swords drew a ring directly on the neck of the Gray-Scale Demon, and then they separated and fell a short distance away.
And this Gray-Scale Demon had already spat out blood and collapsed to the ground, greatly embittered.
If he had encountered it head-on in a battlefield, this monster would definitely have been an extremely difficult opponent. However, there were no ifs in the real world.
A real battle would not just be a contest of strength between the two of them. The timing, location, and people would all affect the final outcome of the battle.
Xiang Yang chopped off the other arm blocking the doorway, which was a narrow exit in the corridor.
These factors allowed Lu Ren to complete the kill in one fell swoop.
[Ding… You have been blessed. You have suddenly used the Twin Swallow Style to kill the Gray-Scale Demon. The proficiency of your Basic Sword Technique has increased by 100.]
Divine Galloping Horse Treading on Twin Swallows!
Lu Ren could not help but retorted in his heart. He picked up the weapons and looked at Xiang Yang. "Lead the way."
Only then did the stunned Xiang Yang react. She gestured in shock and said, "You killed it just like that??"
"What else? Did you think that the outcome would only be determined after hundreds of rounds?"
"No, I'm saying that the monster was clearly very powerful. I had thought it would be very difficult for us to eliminate it."
"In a situation where your attack power is high and your defense is low, the best solution is to end the battle quickly. The other party might be able to withstand dozens of blows from you, but if you had been hit once by the other party, it would have been over. Therefore, in a life and death battle, you must aim for the other party's vital points and attack."
