Xu Bai walked while checking the mission information on his armed badge.

So far, he has killed 18 "Mutant Patients", gaining a total of 18 kill points and 18 growth points. However, it is still far from being promoted to the next realm.

At this time, he found that Liu Qing in the back had already followed, and he couldn't help frowning slightly, stopped, and said with his head slightly sideways:

"Didn't you hear me, don't come along."

When the words fell, Liu Qing, who followed closely, immediately showed a little cramped expression, but still said with a firm gaze: "I know you are very powerful, but I must see my dad return safely with my own eyes, otherwise I will not worry." ”

Finding that Xu Bai frowned, she was apprehensive in her heart, and hurriedly added: "Don't worry, I, I participated in many sprint races when I was in school, I can't beat them, and I can still run away." The tone was low, obviously not as confident as she was saying.

"I'm not interested in hearing that from you." Xu Bai looked ahead indifferently, and said in a deep voice: "I made it very clear before, I came here to save your father, just to pay off the kindness I owed to your Liu family back then, and after this incident, I will have nothing to do with your Liu family." I won't stop you if you want to die, so be it. ”

With that, he quickened his pace and walked to the staircase on the third floor, not far away.

Looking at Xu Bai's departing back, Liu Qing felt uncomfortable for a while, and there was an indescribable sense of grievance.

After hesitating for a moment, she gritted her teeth and continued to follow.

Roar!

As soon as Xu Bai entered the staircase, a strong fishy wind suddenly struck.

A "mutant patient" was actually hiding here, and at the moment when Xu Bai revealed his figure, he suddenly attacked.

Xu Bai was not flustered, calmly avoided the opponent's sharp claw attack sideways, and suddenly swept his legs, kicking the opponent to the ground, and at the same time, with the force of his hand, the extremely sharp steel knife slashed down diagonally quickly.

In a flash of the knife, before the "mutant patient" landed, a deep blood mark appeared on his neck-

Seal your throat with a knife!

Guro~

The body of the "mutant patient" fell to the ground heavily, his head was directly cut open, rolled a few times, and fell down the staircase.

Liu Qing, who came over, saw this scene, subconsciously closed her eyes, gritted her teeth and endured the strong nausea and fear in her heart, so that she didn't let out an exclamation - her psychological quality is still good.

Xu Bai calmly stepped over the other party's corpse and climbed the stone steps on the third floor, followed by a roar, and the footsteps were heavy and fast.

The next moment, I saw a ragged "mutant patient" appear at the staircase, pounced directly from the upper floor, menacing, with his arms open in mid-air, and his mouth let out an excited roar, as if he wanted to have a "close contact" with Xu Bai.

"Look for death!"

Xu Bai's eyes were cold, and while taking a step back, his body sank slightly, the muscles of his right arm were bulging, and the steel knife he was holding pulled back violently, and then suddenly exerted force, from bottom to top, and slashed head-on!

Woola!

The sword light tore through the air, making an amazing low whistling sound, and the speed of the knife was far beyond the nerve reaction of ordinary people, and even left a faint afterimage in the air.

Liu Qing in the back just opened her eyes, and before she could see what was happening, the "mutant patient" who pounced down from above had already split into two, and the two bloody bodies that had split apart smashed heavily on the stairs, blood splattered, and all kinds of rancid internal organs poured to the ground, making people shudder to watch.

Xu Bai lifted the knife and jumped lightly, and jumped over the corpse of the "mutant patient" and climbed a higher step.

At the same time, the prompt of the armed coat of arms suddenly sounded in his mind:

"Make sure the host has comprehended the Swordsman's exclusive primary combat skill: Wind Slash!"

"Note: The host has successfully activated the Personal Hidden Mission: The First Skill Comprehension in the Region!"

"The host has received the reward for this personal hidden mission: a bottle of first-level enhanced potion (physique system), a mortal-level armed glaive knife (top grade), and the items have been transferred to the storage space, please check it yourself."

After listening to the prompt sound, Xu Bai couldn't help but feel happy in his heart.

He had just performed a basic skill of the Swordsman, which, as the Armed Emblem said, was called Wind Slash.

The so-called combat skills are all kinds of powerful combat skills that can be mastered by those who are armed with ability.

Just like profound martial arts moves, each combat technique contains complex power skills, which are displayed through specific techniques, and have extremely strong lethality in actual combat.

For newcomers to armed ability, even the most basic combat skills need to be explored and practiced for a long time before they can gradually master the tricks.

Xu Bai is different, with twenty years of experience in survival and fighting, he has mastered the exclusive combat skills of various swordsmen.

Although he is unable to perform some advanced combat skills due to his current low combat power attributes, for now, a primary combat skill like Wind Slash is enough for him to use against most of the Blood Evil Virus infected.

"I didn't think this was a hidden mission, it's interesting..."

The corners of Xu Bai's mouth raised a chuckle.

The reward given by the armed emblem this time is not only a bottle of first-level strengthening potion of the physique system, but also comes with a high-grade mortal-level armed glaive knife, although it is not as good as the Xuan-level armed Falling Star Bow, but it can be regarded as a very good swordsman weapon at present.

You must know that the stainless steel knife in Xu Bai's hand is only defined as a low-grade mortal-level weapon.

Obviously, the difficulty level defined by the Armed Empalsm for this hidden mission is much higher than that of the previous hidden mission, "Regional First Killer", so that he can additionally obtain the high-grade mortal-level armed glaive.

"With this Glaive Knife, it's much easier for me to do things next."

Thinking about it, Xu Bai was determined.

He didn't rush to take out the Glaive Knife, a stainless steel knife was enough to deal with these primary blood virus infections who had just mutated right now.

Walking briskly up to the third floor, Xu Bai walked outside the slightly narrow corridor, his ears moved slightly, and then he turned around and looked at the end of the corridor.

Dense and heavy footsteps came from far and near, accompanied by a burst of low, frustrating and panicked roars.

I saw a whole group of "mutant patients" rushing out of the corner of the passage, covered in black gas, with blood stained on their tattered hospital gowns, and even fragments of flesh and internal organs hanging from their mouths.

Seeing where Xu Bai was, "they" let out a high-pitched roar in unison, straightened their sharp blood-stained fingers and claws, and rushed towards them even faster.

"Come on, kill it!"

Xu Bai's eyes were cold, and he slowly raised the stainless steel knife in his hand that was constantly dripping blood, and faced the seven or eight "mutant patients", walking without hurry or impatience, and walked up single-handedly-
