(Girls' Literature)

When Song Nan and Tang Shu appeared outside again, it was already completely dark.

It's no wonder that when Song Nan and Tang Shu entered the space, it was already close to evening, and they slept in the space again, and when they came out, it was at least three or four hours outside, and it was normal for it to be dark.

It's just that as soon as they appeared, a figure suddenly pounced on them from behind the side. Tang Shu's fireball and Song Nan's quick-firing dagger directly pinned out the figure that rushed over.

But then, one after another figures rushed in the direction of the two.

It's a zombie!

Song Nan vigilantly threw out more than a dozen wires, and quickly "netted" around them with the help of the branches of the trunk, the zombies in the vicinity still needed to be eliminated one by one, but those in the distance were cut one by one by the wires. It's a delight!

Tang Shu and Song Nan were still surrounded by four or five zombies, and Song Nan carried a sword in his hand and cut it down again and again; Tang Shu's fireballs burned out huge human-shaped torches one after another, and they could still rush forward in front of them for three or five minutes, but they were burned and could not move again, and finally turned into ashes and disappeared.

The battle in the dark of night is really not good for two humans with normal sight. Song Nan and Tang Shu were back to back, and two flames burned in the farthest part of the metal mesh, barely illuminated.

The zombies who were eyeing each other were roaring threateningly, because of Song Nan's wire mesh, those zombies could only roar outside from afar, but they didn't dare to rush in.

Fortunately, there are no high-level ability zombies here now, otherwise, Song Nan's wire is estimated to not last long.

The two had agreed before that when they got out of the space, they must quickly find the direction of the base, and then enter the base on the shortest route.

However, under the safety of this time, as soon as Song Nan's spiritual power unfolded, although he found the direction of the base, he frowned and did not speak for the first time.

Tang Shu did not urge Song Nan either, but constantly agitated his abilities, exuding a coercive momentum, which made those zombies who had recovered some of their senses afraid and did not dare to rush forward.

It wasn't until half an hour later that Song Nan looked at Tang Shu a little strangely: "I saw that there was a strange device in the base. The person next to the device seems to be a person from the research institute. ”

A research institute that will never go away!

Tang Shuweirin: "Let's talk about the advanced base." ”

"But they don't seem to need help." Song Nan was even more helpless: "I 'heard' them say that once the device is turned on, when the frequency waves are different, it will drive away zombies, sea beasts or birds." ”

This is not an exaggeration by Song Nan himself, but by the people in the research institute themselves.

Tang Shu was a little surprised: "Such a magical thing? How did it get here? Will it really work? ”

Song Nan pouted, it will definitely work!

She had already confirmed that in this research institute, there must be people from previous lives who were reborn! Moreover, he can be in charge of the design and development of various scientific research equipment and exotropic drugs.

From the detector at the gate of the Shengjing base, to the upgraded potion that Gao Rongxin had in mind that was bought, and now this one, it can almost be regarded as a frequency fluctuator made by a god - of course, this is only a temporary god work.

The frequency fluctuator, as its name suggests, does rely on the difference in frequency bands, and can drive away mutant beasts, zombies, and so on that are classified according to different brain wavelengths. This weapon is very effective against Mutant Birds and Mutant Sea Beasts, as they are far more sensitive to sound waves than all other creatures and zombies. But again, after this weapon was developed for a while, it was eliminated by the gradually evolving mutant birds and sea beasts.

Because, after the death of mutant birds and sea beasts, those who could not resist the sonic attack, all passively selected the inferior individuals, and the remaining ones were excellent individuals. They evolved, progressed, and finally were able to completely resist the attacks of the frequency fluctuators, and it took only two weeks.

Song Nan wanted to praise the ingenuity of this designer, but also wanted to scold him for why he wasted so much manpower and material resources, just for the short-term stability of two weeks.

Besides, this is not his own ingenuity, but the way he stole after thousands of attempts by his predecessors to finally find it. And now, he is obviously plagiarizing the path of his predecessors, but he is plagiarizing a path that should not be plagiarized the least.

The frequency fluctuator is recognized as one of the most frivolous inventions in the previous life. It can't even be applied to other designs, and can only be gradually buried in the ridiculed history.

Song Nan shook his head: "That thing is very useful, in a short period of time, it should be safe here." ”

Tang Shu looked at it questioningly: "How do you know?" ”

"They've turned on the machine, and now the zombies near the city gate are backing up frantically, and they're going to be back here soon. Do we hide on the walls, or do we go back to the space to hide? ”

"On the walls." As soon as Tang Shu's words fell, Song Nan's arm instantly pointed in one direction, Tang Shu's immediately pushed his hand forward, and the raging flames ignited, and the zombies that stopped in that direction instantly turned into ashes.

Song Nan was surprised, and hurriedly followed Tang Shu in the direction of the city wall.

When he was in space, because Tang Shu saw the situation of dissolving the crystal nucleus, Song Nan demonstrated it to Tang Shu alone. In order to show how strange this well water was, Song Nan deliberately chose the highest-level third-order white core in her hand, and even Song Nan herself didn't know where she got this white core.

Half a cup of colorless and tasteless clean water that was dissolved, Tang Shu drank it all in one go. When I drank it, I immediately found the surging and abundant energy, and it took three hours to absorb it in the space before I regained my calm.

At that time, Tang Shu was nothing unusual, so Song Nan only thought that this crystal nucleus did not make Tang Shu make any substantial progress. But now it seems that Tang Shu's flame burning ability has significantly improved! Normally, it would have to be burned for half a minute and a minute, but just now, with a wave of his full strength, Tang Shu actually burned several second-order zombies in an instant.

This strength leap is obviously very big!

Song Nan followed behind Tang Shu, and the two of them were like ghosts walking in the middle of the night, drifting through the barrier of the forest and jumping lightly onto the five-person high city wall.

On the city wall, Tang Shu and Song Nan could clearly see that the zombie group gate that was still facing the base in the afternoon was actually fleeing towards this side as if they were fleeing in the middle of the day.

"What are these zombies afraid of? Is it the sonic attack you are talking about? ”

"Zombies also have a frequency unique to zombies, but we are different species, so we humans can't feel it." Therefore, although the plagiarism king is plagiarizing the efforts of the previous world, Song Nan still admires him sincerely. After all, he still turned this completely inaudible and intangible thing into a substantial means of attack.

Tang Shu paused for a second: "If humans can't capture it, then this designer is also very talented." "And how can talented people be from the institute? What kind of charm does the institute have, so that they can all flock to it and serve it like crazy.

And how can he be regarded as the number one enemy by the entire research institute, and almost do his best to deal with him alone.

The two of them lurked in the night, watching the zombie army flee and gradually disappear into the forest.

As the zombies got farther and farther away, there was finally a cheer in front of the base.

The zombie siege was so easy to solve?

Tang Shu was full of incredulity, but Song Nan sighed almost imperceptibly.

Wait until tomorrow, and the nightmare will just begin.

"Let's go into the space to rest, there's nothing we need here anymore." After Tang Shu said half of it, he stopped talking, Song Nan raised his head, and Tang Shu spoke: "Anan, have you seen Zhou Xian and Lian Zina?" ”

After all, she is the granddaughter of her chief, and it is normal for Tang Shu not to rest assured. Song Nan shook his head: "Even that passenger car is nowhere to be seen, they should have listened to my suggestion and went east along the coastline, directly from the inland, and crossed this coastline." ”

Tang Shu nodded slightly: "Okay." ”

Song Nan grabbed his sleeve, and the two dodged into the space.

There are still about five hours before dawn in the outside world, and twenty hours in the space, Song Nan decided to go and tidy up his farm and pasture, and Tang Shu said that he would also follow. Yuan Xiaolin had already woken up, but Meow was still asleep, but her condition was stable, so Yuan Xiaolin was also very relieved, chasing after Song Nan and asking long and short questions.

"Sister, how did you save Meow?" "Give it a crystal nucleus."

"Sister, what crystal nucleus did you give Meow to eat?" "The crystal nucleus of zombies."

"Sister, Meow is from the space department, isn't it green for you to give it?" "There is well water, don't be afraid."

"Sister..."

"Xiao Lin!" Song Nan finally couldn't help but clench a duck egg in his hand and handed it to Yuan Xiaolin: "Go, put it in the refrigerator in the kitchen." ”

Yuan Xiaolin took the duck egg in a daze, nodded, and ran back to the villa to put the eggs.

"You actually lie to Xiao Lin." Tang Shu chuckled, he thought that Song Nan would only unconditionally accommodate Yuan Xiaolin.

Song Nan looked up, but happened to see Tang Shu holding a chicken in one hand and three green onions in the other, with his sleeves rolled up. However, he has a gentle appearance, which cannot be compared with greasy iron pots, but is more like those gentleman chefs with high hats in pastry restaurants.

"What are you trying to do here?" The chicken in Tang Shu's hand was jumping around, obviously knowing that his life was short, and he was almost fluttering with the greatest strength. However, Tang Shu trapped it to death, and the big rooster was stunned and couldn't break free.

"Since yesterday, this rooster and the other have been fighting very fiercely, a mountain does not allow two tigers, a circle does not allow two chickens, let me stew a chicken soup." However, Tang Shu's mouth was talking about funny jokes like limericks, and the expression on his face was warm and clean, and no one could see that he was about to swing a knife and slaughter chickens.

Song Nan was shocked by this huge contrast, his mouth opened and closed, and finally said: "There are many small fresh mushrooms in the warehouse, and I still have wide noodles, let's stew mushrooms with chicken!" ”
