——AD.2157.4.21——

College City.

Due to a strange "earthquake", the three "students" who came to look for aliens did not look good after observing the underground in their own way.

The location of the epicenter of the earthquake is a whole gray rock layer that is expected to be half the size of the academy city, and it has obvious gaps with other rock masses around it, it seems that the earthquake just now is only caused by the slight dislocation of this rock layer, but the question is, how can an ordinary rock formation emit that kind of special sound waves that can only be detected by the "old days" and "external gods"?

After careful observation, Kaos found that this rock formation was a little toothache, it was clearly a super giant sand devil insect coiled up and almost became a fossil, its appearance was different from those small ones that sprang out of the ground from time to time to make trouble, no, the miniature sand devil worm has many obvious differences, and it is likely to be the ancient ancestor of all the sand devil insects on Europa VII.

Although I don't know where it came from, since it had been sleeping all the time, and now it suddenly showed signs of awakening, no matter how you think about it, it can't be separated from those alien fleets that suddenly arrived, most of them were old enemies in ancient times.

"Hey, Silly Hair Spirit, are you going to say that you discovered it a long time ago, and this time you brought us here in the name of looking for aliens to solve it?" Out of nowhere, Kelly pulled out a fork and aimed at Naia's head, intentionally or unintentionally, with an expression that she dared to poke at without saying anything.

"This kind of thing is bound to cause a lot of trouble, if Naia says you don't know, I don't believe it." Kaos also took a stand.

"Ahaha...... Of course, I brought you here to deal with it, just by looking at its location, you can know that the space-time rift was caused by its fall," Naia rolled her green eyes, "Otherwise, is it so that you can deal with aliens?" ”

Not...... Judging by this reaction, she should indeed know that there is something here that can only be solved by a few "people" present, but she underestimated the harm of this thing, and is a bit blind now.

"So, what's next for you?" Naturally, Kelly will not let go of Naia's flaws.

"How about we just go underground and suppress it?" Naia said as she said something that was clearly a made-up countermeasure.

Apparently very unhappy with this answer, she raised her eyebrows and was about to growl, but was stopped by Kaos.

"With Europa VII's current level of technology, it really won't help to deal with that thing, and the people who can solve it are already here," Kaos took Crowley's fork, "It's obvious that there will be no foreign aid in this operation, and it will eventually go deep into the ground, and what Naia said is actually not too much wrong." ”

"So what do you say?" Kelly was still puffing out, and her eyes were bigger than usual.

"Find a nearby shelter first, register it to reassure the Governor's Palace, and then dig a hole in the ground yourself." Kaos turns on the multi-tool and starts looking up the location of nearby shelters.

"Uh-huh," said Kerry, noncommittal, "If all goes well, you can indeed go back to being your good baby, but if something happens and you have to give it your all, just say goodbye to your daily routine." ”

"If that happens, it must be Naia's fault." Kaos shook the pot smoothly.

Naia's dull hair trembled, and she gave up again when she wanted to say something.

Vault 101 College City.

"Naia Quercie, Kerry Crowder, Kaos Crowder, registration is complete," said the staff at the door of the shelter as they wrote down the names of the three teenagers and girls on a record board, "Have you forgotten how you did the alarm drill now?" If I were your teacher, I would have scolded you severely. ”

Scolding three old days and outer gods at once, that's a record, Kaos complained in his heart, and still nodded obediently on the surface.

"We want to see what the aliens look like~ I didn't see anything~" Kelly is the youngest in appearance, and directly began to sell cute.

"There's nothing to look at, it's probably the kind of little green man with big heads and big eyes, okay, let's get in." At first glance, this staff member is a science fiction movie lover.

Seriously, those exoskeleton lizardmen and their silver-white shuttle-shaped ships are still quite handsome, and the current battle situation is ......

Kaos paid a little attention to the space battle before entering, and the aliens had survived the first wave of blows and began to fight back against the Third Fleet.

Unlike the battleships in various science fiction film and television works in which the warships are neatly arranged to bombard each other, the space battlefield at this time looks like someone has stabbed a hornet's nest, almost none of them stay in place, and the heavy ships are pulling at the same time on the missile range, the control distance of the drone, the influence range of the energy absorbing device, the jump disruptor jamming frequency band and other functions with range limitations, while the light ships take the initiative to block the mass effect cannon with a range sufficient to cross the battlefield with high evasion, and the battleships of the entire battlefield are in the "orbiting a target" at any time The state of the state looks dizzying.

In the battlefield rehearsal of the Star Alliance, this chaotic battle usually ends with the injury of one side's capital ship and exit, but it seems that it is still very early.

After sending Zhou a message that he had entered the Vault, Kaos followed Naia and Kerry as they weaved between the nervous or agitated Vaulters as they began to "scan" the Vault.

Perhaps the underground shelters on other planets were dug by engineering equipment, but most of the shelters on Europa VII are former sand devil nests, so there is an urban mystery as to why the layout of each shelter is different.

Since the shelters themselves are designed to deal with large-scale events such as "alien invasions", "major natural disasters", and "biochemical material leaks", they will all have equipment to purify water and air, miniature factories to produce food, small power stations to produce electricity, and so on.

The functional chambers themselves were nothing to look at, and Kaos himself had to find a place where he could burrow into the ground without causing problems with the shelter's structure and press the awakening bug back down.

If you want to talk about the "old days" or "outer gods" that look like insects, Kaos only has "Xiude Meier" in his impression, if I remember correctly, Xiude Meier is probably "Qiu Yin", of course, it may also be because he doesn't like those humanoid guys so he doesn't pay much attention to it.

As for the giant petrified sand demon insect that is gradually waking up in the underground of the academy city at this moment, since it has traveled through the universe, it is not the guy who can only eat soil.

Oh, here.

After repeatedly "scanning" the bottom floor of the Vault, Kaos found a gap that was presumably caused by a mistake in construction, through which he could directly touch the soil, and the Vault guards created a small garden where they planted some plants.

If you dig down from the small garden, you can help them loosen the soil...... bar.
