An hour later, the two girls finally came back.

As long as the zombies with slightly stronger strength are all swept away, whether it is the corpse king corpse general who trained them, or the blue-striped zombie chasing after the fart, none of them survived.

It can be said that at least seventy percent of the zombies in Salt Mine City died at their hands.

The two girls came back from hard work, and when they saw Leng Mo leisurely eating snacks, their faces were very ugly, but the anger was only temporary, and after just a few minutes, they stopped caring about the greeting for a few seconds.

"It turns out that the battle in the clouds is so thrilling, what about her?" Nangong Yu asked.

"You didn't see that?" Leng Mo had just finished his drink, and his eyes were a little surprised.

"Just now you said that the blood angel ran to find the map, how long did you go?" Gongsun Meng asked.

"There should be, thirty-five minutes." Leng Mo looked at the time on the small spaceship.

Bang bang!

The Blood Angel seized the opportunity for the two women to ask, jumped back to the top floor of the building, and grinned and held a rubbing.

It was she who traveled to all the major public institutions in the city, and then to the hospitals and various major buildings, to find a real underground sewer map.

To this end, she killed about 20% of the other zombies, and used special materials to rub a picture, which is invulnerable.

"Underground sewer map?" Nangong Yu was investigating this city before, and all the surface ones were checked, but the underground ones were not found.

The Blood Angel nodded: "Yes, it's the underground sewer map, you just ran through all the buildings, except for zombies, it's all rotten things, right?" ”

"Yes, even if there are any weapons left, they are completely rusted, but I found one interesting point." Gongsun Meng and others want to tell their findings.

"Let the Blood Angel speak first." Nangong Yu knew what Gongsun Dream was talking about.

After Gongsun Meng was quiet, the blood angel explained quite seriously: "You should also be aware of the strangeness of this city, in addition to the lack of zombies on the streets, there are also very few zombies in the buildings, not to mention the sporadic number of corpse kings, which makes people feel as if this is a city abandoned by zombies." ”

"But how can a zombie abandon a city? Zombies are everywhere in the world except for humans! ”

"So since there is nothing on the surface, the problem must be below, but the ordinary sewer is not our goal, but the lifeblood of the salt mine city, the underground salt vein map!"

"At present, the underground water channel map in my hand is a special map made by combining the underground salt vein map, and maybe in it, you can find out what plans the dark city has made."

Although Nangong Yu was very happy to hear the news, he immediately frowned and said, "Three hundred years ago, will the salt vein diagram be the same as the current one?" ”

"Probably there will be no change." Gongsun Meng suddenly jumped out and promised.

"How do you know?"

Leng Mo was surprised, when did Gongsun Meng become so professional in geography?

"Because the feng shui here is different, the city setting point is specially selected by the feng shui master, the ordinary wind and clouds and underground water veins, will not pass through here at all, and the rain will not fall within a radius of 100 miles, if the city does not build a super reservoir nearby, I am afraid it is a permanent arid area." Gongsun Meng used his knowledge of Feng Shui to help them sort out the city's climate information.

"I see, the wind fruit is really a strange knowledge." The Blood Angel learned.

"So, you're going down to explore?" Nangong Yu couldn't wait to ask.

Although she had been on the mission for two hours, she didn't feel tired at all, especially when she heard that there was an update, and she wanted to go to the test quickly.

After all, if she buys a little more time, she can bring a little more hope to the human world, and she doesn't want to see the Four Seasons Battlefield, or the huge walls and embankments built by humans more than a hundred years ago, destroyed by emerald-level zombies.

"Wait."

Leng Mo threw out seven energy cores from behind him and placed them in front of the third girl, waiting for the blood angel to speak.

"Oh? Is this the energy core? "Gongsun Meng has seen it.

"Seven of them, from the mechanical sparrows?" Nangong Yu asked.

"Yes, let's see if there's a way to untie it now." Leng Mo believes that there must be residual information in this.

The Blood Angel picked up one of them and said with a wry smile, "It will take a little time." ”

"How long?" Nangong Yu is willing to wait, but if it takes more than half a day to unlock the core, it is better to go down and investigate first.

"Three hours." The Blood Angel touched the seven cores and gave the calculated answer.

"Wait." Leng Mo didn't want to be reckless, so he ran down to investigate first.

"Three hours is just enough rest, it's okay." Gongsun Meng ran for a long time, planning to take a break before acting.

After everyone discussed, Nangong Yu and Gongsun Dream went to rest inside the small spaceship, while the Blood Angel tinkered with the equipment outside the small spaceship, trying to completely crack the shell of the seven cores and the program protection inside.

And the task of monitoring the entire salt mine city was entrusted to Leng Mo.

He picked up the salty sparkling brine and took a few sips, feeling weird, but still drinking it.

I heard that ancient people would drink this kind of thing, so from the perspective of a chef, he had to taste all the strange flavors of ingredients and surprising seasonings, and this special brine belongs to the scope of special seasonings.

"Salt Flower Salt Flower, could it be that under the salt vein, there will be neon dress-level ingredients?"

Leng Mo adjusted the telescope every few minutes and spread the time realm so that the danger would not sneak near without anyone noticing.

It's just that the remaining zombies are really quite quiet.

The deserted city has really become a deserted city!

The wind kept blowing through Leng Mo's somewhat handsome face, the sun was sinking in the west, the sunset was shining on the earth, and the whole sky was orange-red, especially the red-hot clouds, which were very beautiful and refreshing.

Looking at the sky, looking at the empty city like an illusion, a sense of emptiness hit me.

Sometimes he really can't figure out why he is so enthusiastic that he desperately wants to save mankind, even if the Seven Great Families gradually falls, he can't let go of this responsibility, swallowing the heavy responsibility given by the time.

"Dazed, only for a moment, not lost."

Nangong Yu actually woke up and sat beside him.

"Seven families, can you let it go?" Leng Mo asked.

"It's not a question of whether you can let it go or not, I'm the same as you, it's impossible to abandon the human world, and the Nangong family is all my clansmen, no matter how worried they are about being afraid of confronting the zombie world, although they are selfish, but after all, it's for the sake of the family, we can't think of the other party as heinous because of the other party's selfishness, let alone come to the zombie world, so we gave up the seven families that have guarded the human world for more than two hundred years, I believe the Shangguan family also thinks so." Nangong Yu knew the knot in Leng Mo's heart, and knew better the vicissitudes of life when he looked at the sky.

"I see." Leng Mo nodded and sighed slightly.
