With Ovo as a guide, the team easily walked through the cave full of forks in the road and made a straight path to the goal.

Dozens of kilometers of distance, nearly 100 forks, in Ovo's eyes, is nothing at all, this huge labyrinth seems to be her children's paradise, you will not get lost with your eyes closed.

Ovo threw a ball of flour barley into his big mouth and swallowed it without chewing: "Well, this thing tastes good, how can you have so much delicious food?" ”

For the dragon, who eats rocks and moss all year round, it seems as if any food is a delicacy that she has never eaten.

Mamie sighed in her heart, this Owo is a big stomach, and the amount of food for one person is more than ten people.

Of course, thinking of the size of her body, it is estimated that eating such a little thing is only enough to stuff her teeth.

"Anyway, Owo, do you live alone in this cave world? Since you've been to the elevator, why haven't you thought about going to the other floors? ”

Ovo habitually licked his lips and said, "I can't open the elevator to the lower level, but I can sit on the upper level." ”

She tilted her head and said, "There is water everywhere on the upper floor, and I haven't found a place to stay after flying there for a long time, so it's boring." ”

"On the upper floor, it's cold in that place, so I don't want to go there, I might as well go back to my own nest and get some sleep."

Mamie captures the message of her words, the upper layer is full of water, and the upper level, is a cold world.

This news is very important to the team, who need more information about the upper world.

"And have you seen any other humans in other levels? Including human settlements and large cities? ”

Owo thought for a moment and said, "I think there's one on the upper floor, and I see some light, similar to your headlights, but it's really cold in there." ”

She shuddered: "I only stayed for a while and then came back, woo woo, I don't want to go to that place." ”

It took about a day for the large army to make their way through dozens of caverns before finally reaching the core hub heading to the upper levels.

There's also a huge blue-light platform with transparent vertical channels that go straight above the dome.

"Lias, Owo said that the upper level is the water world, if we don't see the city, we choose to skip it and prepare to go directly to the upper level." Mamba said to the first group to set off in the spirit network.

Lias nodded, "Everyone re-check the multi-purpose suit to make sure it's safe." ”

"Ovo said that the upper level is a cold world, and we don't know exactly how cold it is, and everyone should be prepared for the cold."

Mamba concluded: "The other teams will stay where they are and wait until the advance team has confirmed the news. ”

"Lias, in the event of a possible enemy, I authorize you to open fire at any time, and you must ensure your own safety!"

Lias replied: "You can rest assured that I will do things! ”

……

The first wave of advance teams, a total of fifteen combat vehicles, drove into the Blu-ray platform.

The platform quickly ascended along the pipe, and after passing through the apertures, the platform reached the middle level of this core hub.

It was an endless ocean, with no place to settle outside the core hub, and there was no light in the entire world.

Lias cautiously walked to the edge of the blue platform, looking at the almost unwavering water in front of him, he planned to taste the water here to see if he could drink it.

The team's water resources have always been a bit scarce, and if they could be replenished here, it would be greatly alleviated.

However, when his hand touched the water, it was clear that something was wrong.

What he touched didn't seem to be water, but a liquid with a certain viscosity.

At the same time, he felt a slimy sensation on his hand, and the liquid stuck to his hand like a layer of greasy.

Lias almost jumped away from the water's edge, quickly drying his palms and informing the other members: "Be careful, don't go near the water, don't go near the water, there's something wrong with the water here!" ”

……

Tang Hao's gaze also moved to the calm water, about these somewhat strange liquids, the item information given on the screen was: "Colony slime".

"Adjutant, what is this? Mucous? Tang Hao asked with some confusion.

The base intelligence lieutenant replied: "Judging from the item information, these liquids with some viscous consistency should be secreted by some special fungus. ”

"With so much mucus, it can be seen that under this sea of slime, there must be a large amount of bacteria hidden in it."

"It is recommended not to come into contact with these bacteria, and in the absence of a judgment on their status and food chain, rash contact is likely to cause extremely serious infection."

Tang Hao looked at the "sea" on the screen: "It seems that Owo is right, there is really nothing on this layer, everything that originally existed has been eaten and wiped clean by those bacteria." ”

……

Passing through the middle level, the advance team continued to set off towards the upper level without stopping.

With the information provided by Owo, everyone put on the multifunctional protective suit in advance and turned on the full protection function.

While the blue platform was still on its way, everyone in the advance team had already felt the change in temperature.

"Now the temperature has dropped to freezing." Lias looked at the temperature display on the multifunctional suit and said, "The temperature is still dropping. ”

White mist began to appear on everyone's masks, but soon the suit activated the automatic defogging function, and everyone saw condensed frost flowers on the surface of the vehicle.

"The temperature dropped to minus 20 degrees." Lias wasn't very worried, after all, the expedition team of the "fortress" city had even reached a higher world, and their protection ability could not be compared to the "journey to the underworld" at all.

Soon, the Blu-ray platform reached its destination, and after the platform came to a stop, Lias saw the temperature on the suit showing -40°C.

"minus 40 degrees, if there is enough warm clothing, ordinary people should be able to support it." Lias reports to Mamba in the spirit network.

Outside the core hub was a pitch-black world, where the ground was thick with permafrost, and Lias went out for a walk in his chariot without seeing any animals or plants.

After turning off all light sources, he could only see some faint brightness in the distance.

That should be what Owo said, the human gathering place that may exist in this world, it is barely estimated that it should be ten or twenty kilometers away from here.

After conducting initial reconnaissance and confirming that there was no obvious threat in the vicinity, Lias directed the advance party to disperse and prepare for defense.

"Mamba, you can come up."
