"Yangtze River No. 3, you're finally back!" Bu Fan looked at the Yangtze River No. 3 that flew to his side and said with a smile.

And the Yangtze River No. 3 exploration robot instantly turned into an intelligent robot at this time and appeared in front of Bufan.

"Yes, master, Yangtze River No. 3 has returned from completing its mission, hahaha!" Yangtze River No. 3 said with a shrill smile at this time.

"So the tasks I assigned to you have been completed?"

When the Yangtze River No. 3 was initially sent out, it was necessary to let it explore the location of the city and the situation inside, plus to check the surrounding terrain of the blood-colored hills.

"Of course, master, please wait!" After the Yangtze River No. 3 finished speaking, the two slender tentacles merged together at this time, and then inserted into the handheld computer in Bu Fan's hand.

Immediately, Bufan's handheld computer began to show the style of data transfer.

After about three minutes, the data transmission was completed, and Bu Fan found the transmitted data, only to see that there were two data displays in it.

The first item is the Scarlet Hills topographic map and creature types!

The second item is the underground city data model!

Bu Fan first knocked on the first data icon, and then a huge electronic map appeared in front of Bu Fan's eyes.

With the touch and swipe of Bufan's finger, the map can be freely enlarged or even zoomed out, and it looks just like the electronic map of the previous life.

"Master, because you only let me explore the terrain and creatures of the blood-colored hills, I didn't collect data, so there are many mutated creatures in it, only images, no specific information about the creatures!"

Bu Fan nodded, he knew that the Yangtze River No. 3 could also collect data from various creatures, but because of the time relationship, Bu Fan didn't have time to let it do such a detailed data collection!

"By the way, do you recognize this thing? Have you ever encountered it? Bu Fan looked at the map. While casually taking out the corpse of the vine demon, he asked at the Yangtze River No. 3.

"Well, I've encountered it, and there are a lot of them in Area Eight! It should be a wood attribute mutant plant beast body, and I see many people use its corpse to make clothes! Yangtze River No. 3 replied truthfully.

Bu Fan knew what the No. 8 area of the Yangtze River No. 3 was, and it was the area marked on the map. Yangtze River No. 3 marked eight different areas for the blood-colored hills, marked by numbers!

"Making clothes? A lot of people? Is it an adventurer? When Bu Fan heard the words of Yangtze River No. 3, he couldn't help but show a trace of surprise on his face.

Speaking of which, he has been in the Scarlet Hills for so many days, counting the days when he acted with Captain Greedy Wolf and them before, they have not encountered many adventurers, and Yangtze River No. 3 actually said a lot, which really made Bu Fan feel a little puzzled.

Yangtze River No. 3 shook his mechanical head and said quickly: "It's not an adventurer. It's the aborigines, the primitive inhabitants behind the underground city! Master! ”

"Primitive natives?" When Bu Fan heard the words of Yangtze River No. 3, his face changed, and he was surprised for a while.

The so-called primitive inhabitants are human beings who have not registered in the base city and have been living in the wilderness for a long time.

A large part of such people were at the time of the cataclysm. For various reasons, he was not saved by the large army. And then abandoned in the wilderness, or people who have survived by being lost in the wilderness.

Of course, there is another kind of person, that is, for some reason, people who have been abandoned and expelled by the base and have to wander in the wilderness. They are usually the most vicious people, or have committed many crimes, or have been persecuted by powerful forces for some reason.

For example, the Restoration Army organization, to a certain extent, is a huge primitive inhabitant.

In the wild. If primitive inhabitants are found, they should generally be careful and careful, because either one may represent killing.

Those who can survive for a long time in the cruel wilderness are those with great strength.

"What kind of primitive inhabitants are they?" Bu Fan asked with a solemn face at this time.

"According to my exploration, these people should be the survivors of the underground city, and their residence is just behind the underground city!"

Immediately, Yangtze River No. 3 came to the computer, and a slender tentacle began to click on the computer.

"Master, please see, this is the junction of Area 6 and Area 8, it is an underground canyon running north-south, the canyon is completely undulating hills on both sides, and the underground city that the master is looking for is actually in this underground canyon."

"At the southern end of the canyon, there is a mountain cliff, and outside this mountain cliff, there is a primitive village, and the primitive inhabitants I found are just below this cliff, only a cliff away from the underground city!"

"In addition, I have found a passage through this cliff, connecting the village to the underground city!"

"What about the entrance to the underground city? Hasn't this primitive inhabitant village been discovered by the exploration team? Where is the junction they found? Bu Fan looked at the map displayed by Yangtze River No. 3 and asked in a deep voice.

"At the North End! The entrance to the underground city discovered by the exploration team was due to an earthquake in this area, and the surface was shattered, revealing the entrance to the northern section of the underground canyon, which is also a gathering place for metal zombies! ”

"What do you mean?"

Yangtze River No. 3 did not answer immediately, but opened the data model of the underground city on the computer, and then said to Bu Fan: "Master, this is the underground city you are looking for, and among the underground cities, there are a huge number of metal zombies, the number is about 700,000!" The entire underground city is about 11.2 kilometers away from the exit of the northern canyon! ”

Bu Fan heard the introduction of Yangtze River No. 3, with a surprised look on his face, and then asked in a deep voice: "Why haven't such a large number of zombies migrated out?" ”

"It's because of the law of sleep, these zombies, because of the ban of the underground city, have been sealed for hundreds of years, sleeping in the dark, unfamiliar with the light, so when the sunlight ingests the entrance during the day, these zombies will have a strong stimulating reaction! Only in the dark of night, some zombies will accidentally come out of the canyon and come outside! ”

"But this irritation is only temporary, master, these metal zombies are not afraid of light, but because they are not adaptable, they do not go out on a large scale, when they slowly adapt to the light reaction, zombies will attack in groups!"

The words of Yangtze River No. 3 made Bu Fan's heart heavy at the moment, the number of 700,000 zombies, this is by no means a small number, even if it is an ordinary zombie, 700,000 zombies are enough to bury all the exploration teams in it.

So the high-level leaders of the base city set up this expedition mission, do they know the situation in the underground city? (To be continued......)
