Nan Xiao was so panicked that she dropped the notebook and ran towards his direction.

"Little brat, what are you doing?"

Xiao Huai has now lifted up his sleeves, and the silver needle is pressed against the veins in his arm. He is about to inject a tube of transparent liquid into his body.

And her arrival stopped him.

Xiao Huai also wisely put the things away. Knowing what she was worried about, he smiled and comforted: "Anan, don't worry, I just want to try this developed vaccine. When it is injected into the human body, will there be anything?"

side effect."

"There's no need for you to try it yourself. There will always be one or two people in the base who hide that they have been bitten by zombies. Just let them try it. Do you understand that it's three parts medicine and poison?"

Nan Xiao's tone was extremely cold, which showed that she was really angry. She cared about him so much that she didn't want to see him get hurt at all.

Even if he developed this thing himself, he can't do it.

Xiao Huai also knew that his behavior just now scared her, so he quickly hugged her into his arms and patted her back gently.

"Yes, yes, my wife taught me the right lesson. Damn it, damn it. My brain was chewed by a dog. I didn't even think of the solution that my wife just proposed. I am really the biggest fool in the world."

He wasted no time in degrading himself, and at the same time he kissed her cheek several times, praying with pitiful eyes for a chance to change his ways.

Nan Xiao was held in his arms and coaxed softly. Those words made her lose all her anger. She couldn't even pretend to be angry, so she had to compromise.

"Then don't scare me like this in the future. I'll go to the base later and find someone to turn into a zombie for you. If you secretly inject this thing behind my back, huh..."

Nan Xiao's threatening tone became stronger: "Then you are not allowed to sleep on my bed at night. Go and sleep on the sofa."

Is this okay?

Xiao Huai immediately hugged her slender and soft waist tightly. Such a trump card really made him docile, so he hurriedly agreed.

"No, no, no, Anan, don't worry a million times."

He was confident in his research. Even if there were some side effects, they were within his expectation and he had made preparations in advance.

He used to hate this laboratory, but now he likes it very much.

And besides him and Anan, he didn't want anyone else to stay here.

This is also an important reason why Xiao Huai is willing to regard himself as a guinea pig.

Now, after being threatened, I no longer dare to make a mistake.

Seeing that the scare was successful, Nan Xiao twitched her lips proudly. Just when she was about to say something more, she suddenly heard a complicated and commotion sound below.

Immediately afterwards, the alarm sounded in the base.

It only sounds when the zombie wave comes.

The entire No. 1 base has entered a state of serious alert, and ordinary people and superpowers who need to fight stand at their respective posts.

On the city tower, Xiao Yuan put down the telescope. There are three lines of defense outside the city of Base No. 1. The current zombie wave has conquered the first two lines of defense and is gradually approaching the position very close to the city gate.

On the only way to the third line of defense, there is actually a pit more than ten meters deep. The water in it is just enough to cover a person's head. Zombies fell in one after another, and after entering, they never came out again.

However, their corpses are almost filling the pit. Once it is full, other zombies can step on these corpses and walk over.

Moreover, this pit has no effect on high-level zombies, so they can cross it with a light jump.

If this line of defense is also breached, we can only rely on manpower to kill these zombies bit by bit.

But the difficulties faced by Base No. 1 go beyond that.

"What are those dark things on the left? They don't seem to be zombies."

"It should have come down from that mountain."

"Oh my God! There's a snake! What a big snake!"

Xiao Yuan pushed aside the crowd and walked over. A two-meter-long dark brown python had climbed up along the city wall.

It is not accurate to say that this snake is a python. Compared with a python, it is still too small and looks more like a grown-up ordinary snake.

"Where are the fire powers?" Xiao Yuan asked in a deep voice.

Immediately, several fire power users stood up and burned the snake alive.

Every time there was one, there were two. Snakes kept crawling up the city wall, and there were too many to take care of. Several people were unprepared and were swallowed alive.

During this period, there were not only snakes, but also giant scorpions, giant centipedes, giant spiders and many other poisonous mutated animals.

At the same time, the high-level zombies under the city wall are attacking the people on the wall with mounds of earth and vines, attacking from both sides, and the situation is critical.

Nan Xiao could not see these scenes in the residential area where she was located, so she could only understand the whole story through the communicator.

"Lin Meng, haven't you always encountered these things before when you went up the mountain to collect herbs?"

Lin Meng's hurried voice came from the communicator: "Yes, Sister Nan, I am looking for the realgar powder you developed last time and will send it to them later."

"Well, if you sprinkle it around the city wall, these things won't be able to get up."

"Okay, I know."

Nan Xiao and Xiao Huai have now gone downstairs and are about to rush to the city wall. She calmly commands through the communicator.

"For those high-level zombies, let a few ordinary people with high martial arts values ​​come in first. They should carry concealed weapons with them. Remember, the brain is the weakest part of the zombies."

Almost as soon as she finished speaking, people around her screamed and fled in all directions.

"Ah! Zombies! They are high-level zombies! Call people over for support!"

There is a wave of zombies outside the base. Those who can fight have gone to the front line. The rest are all with weak force value. Of course, they are afraid of facing high-level zombies.

But, why do zombies suddenly appear here?

Nan Xiao had no time to think about this now, and immediately swung the big knife at the two high-level zombies.

She happened to collide with the thick vines that were stretching straight out from them, so she raised her knife and chopped off the vines, then did a backflip and returned to Xiao Huai's side.

"It's weird, these two zombies seem to be able to see me, and their level is not like high-level zombies, but more like the zombie leader we met before."

Xiao Huai buried the two zombies with a lot of sand and said calmly: "If their level is calculated according to the level of superpowers, they should be around level five, and... Anan, do you think these two

Do the zombies look familiar?”

"What? What did you say?"

Nan Xiao's back was pressed against his, looking around warily, not quite understanding what he said.
