When Ning Xuan heard Ning Yu's words, she shook her head firmly and looked straight into Ning Yu's eyes.

"You don't have to worry about my safety. Just use me as a consumable tool."

Ning Yu was touched when she heard this familiar statement, but she still firmly rejected Ning Xuan's request.

"Let me put it another way. If you're not here, I'll be able to fight more easily."

This sentence was a bit hurtful, but Ning Yu had to say it because she didn't want Ning Xuan to waste her life in vain if something happened to her.

Since she was not being chased, she could go to a safe place and wait to solve all these problems.

Ning Xuan pursed her lips stubbornly and remained silent, refusing to give up.

Ning Yu felt helpless seeing her stubborn look. After thinking for a while, she could not help but speak again.

"You have to leave, or I will never see you again, and I will never hug you again."

"I won't call you sister anymore."

Faced with such a stubborn child, she had no choice but to resort to ruthless tactics.

Hearing this, Ning Xuan couldn't help but open her eyes wide, and her lips began to tremble.

She knew clearly that Ning Yu didn't dislike her, she just didn't want her to do this and was considering her.

But she knew that Ning Yu was a man of his word, and she could not bear such a result.

“I, I.”

She stammered, very hesitant. She couldn't bear to let her sister fight alone, but she couldn't bear the consequences.

Ning Yu came over, stroked her head gently and said, "Be good, wait for your sister to deal with them, okay?"

Ning Xuan hesitated for a long time before finally nodding in agreement reluctantly, but her eyes were still filled with reluctance.

Ning Yu has rested and fully recovered from the dizziness just now.

There must be countless zombies behind him heading towards him now, and he should not waste any more time.

She summoned the Blood Kite from the system space, jumped to the top of the ruins, looked at the situation in the distance, her silver hair fluttering in the wind.

The amber eyes took in all the range that the vision could scan, and for the time being, no mutant zombies were seen coming towards this side.

There were only a few ordinary zombies wandering in the streets, and they were obviously locals.

Ning Xuan stood below with a melancholy look in her eyes, staring at her sister's back in a daze.

"I'm leaving, please find a safe place to stay."

Ning Yu stood on a high place, turned around and looked at Ning Xuan again, and made a gesture to her that it was okay.

Ning Xuan wanted to say something else, but when the words came to her lips, they turned into: "Sister, take care of yourself."

"Um."

"Come back alive."

"Um."

"Call me sister again."

"Promise."

After saying that, without waiting for Ning Xuan's next words, Ning Yu jumped down from the top of the ruins and disappeared from Ning Xuan's sight.

Ning Xuan looked at the place where Ning Yu disappeared with loss, feeling a little confused as to where she should go now.

After tidying up her combat uniform and resting for a while, she left the ruins.

Walking in the nearby alleys, Ning Yu casually killed the ordinary zombies wandering here and earned some points.

He analyzed the terrain nearby in his mind, sometimes standing on high places, sometimes falling into corners.

She must make good use of all the conditions here to complete this one-on-ten thousand battle.

Logically speaking, this is not what a killer should do. She should directly assassinate the arrogant Morning Star who controls the zombies and sits high on the throne.

Unfortunately, that guy is too weird. If possible, Ning Yu doesn't want to use her life to test her ability directly.

Moreover, the [Detection (Advanced)] which could no longer be upgraded could not provide more information, let alone reveal her weaknesses.

So compared to this uncertain thing, killing all her subordinates is a better option.

I have the almost invincible [Mist Walking], so theoretically I don't need to be afraid of her attacks. This won't be a problem as long as I'm alone.

Ning Yu used the grappling hook to move between the tall buildings and after getting a clear understanding of the surrounding terrain, he climbed up a tall building and exchanged a high-power military telescope from the system space.

The zombie tide in the distance seems to be emerging, and I'm afraid it will soon reach near me.

Ning Yu opened the system mall and searched for weapons and equipment suitable for dealing with them.

In addition to considering mass lethality, we must also consider cost-effectiveness. After all, our points are not unlimited.

So like last time in the food court, RPG combined with thermobaric bombs is very suitable for dealing with large areas of ordinary zombies. As long as it is fired properly, you can even make points.

But Ning Yu felt that there should be something with a better cost-effectiveness. After all, she didn't have Shen Yiyue's [Future Reading] that was sure to hit a hot weapon.

There is no way to adjust to the only future possibility that will cause the most harm.

Ning Yu suddenly thought that if Shen Yiyue were here at this moment, she might feel a lot more relaxed, but this thought only flashed through her mind.

After all, Ning Yu hoped that she was safe and sound more than the help she could bring to herself.

So we still have to solve the problem at hand by ourselves.

"Well, the flamethrower is nice."

"Incendiary grenades can also be considered"

The system is now full of individual combat weapons. If Ning Yu considers cost-effectiveness, the most suitable way is to cause large-scale burning.

This method should not pose much of a threat to the mutated zombies, but as long as you can ignite the ordinary zombies and let the flames spread among the zombies, they will eventually become nutrients that provide points for you.

Isn't this more exciting than that?

If Ning Yu were to kill herself, she would definitely not drive these ordinary zombies to form a tide of zombies to chase her.

Although it can form a blockade of land movement, it not only cannot restrict Ning Yu, but will allow her to gain more room for maneuver.

She would choose to use only mutant zombies with higher mobility.

However, apart from Ning Yu herself, no one knew that she could gain points from zombies.

So this is simply Ning Yu playing a game with herself in her mind.

After finishing shopping in the mall, Ning Yu glanced at the inventory full of weapons and equipment, feeling quite distressed.

I have to earn it all back later! She moved around the city again, setting up devices and burying grenades and bombs in some key locations.

In the depressed and lonely City A, a dark tide was like a swarm of locusts passing through, destroying everything in its path.

Occasionally, there are unlucky survivors who are suddenly smelled by passing ordinary zombies or mutated zombies, who break in and kill them on the way.

Ning Yu was ready and put down the telescope because the tide of zombies was close enough.
