Tang Hao looked at the big bookcase on the screen, and there were a bunch of black lines on the door of his head.

The first row of books gave him a new understanding of the technological level of the world.

The second row of books lets him know that even in the ruins of the end times, there is such a thing as physiological needs, although Torre's XP is a bit difficult to describe.

The third row of books made Tang Hao completely speechless, it turned out that in this era, there are still cool texts that are prevalent, and although junk food is not nutritious, it will definitely not be eliminated.

It's a pity that Tang Hao can only see the cover of the book, and the specific content is not displayed in the item attributes.

When the power is strong, you must "borrow" the book in Torre.

Tang Hao thought with great resentment.

……

A loud "boom" sound came from outside the building, and everyone hurried to the glassless window to look out.

I saw that the layers of pipes on the periphery of the "fortress" were all moved.

They either rotated or translated, and soon they were pieced together from their previous chaotic state into three concentric circles centered on the "fortress".

That's why the "fortress" is called a fortress.

As a transportation hub connecting the upper and lower floors, it has a certain defense capability, which is a matter of course.

I just don't know if these three defenses can stop the roaring flood.

It was late in the evening when the light strips of the underworld dimmed.

The Mamba took their own spider jerky and barley, mixed it with some water, and it was their dinner.

Mu Qi watched them eat with relish, licked his lips and asked, "Mr. Mamba, are you really sure that there will be a big flood?" ”

Mamba wiped his mouth: "Don't worry, it's absolutely fine, it's just a matter of time." ”

The gathering place is almost three days away from the "fortress", and no matter how fast the flood is, it will take some time to travel such a long distance.

Before Mamba finished speaking, the original pale blue light source outside the window suddenly turned a terrifying red.

The "buzzing" siren also sounded, constantly wafting back and forth in the empty underground space, shaking people's ears numb.

"It's an emergency alert! The entire 'fortress' is in a state of emergency! Muki looked back at Mamba in surprise: "Is it really ......?" ”

"Poof......" A crashing sound came from a distance, especially in the sound of the siren, and everyone looked out of the window, and at the farthest end of the field of vision, a yellow wavy line rushed from the perimeter of the "fortress".

The wavy line slammed into the outermost layer of the defensive pipe, making an earth-shattering crashing sound.

Everyone could even see that the defensive position, which was originally a circle, was actually knocked to pieces, and some of the pipes were like candles in the wind, shaking under the impact of the water.

"Over there! There's that too! Ena exclaimed, pointing in the other direction.

Everyone followed the prestige, and sure enough, not only this one, but the flood gushed out of the pipes in all directions, enveloping the entire "fortress" in the middle.

The flood began to hit the outermost defenses in full force, and the sound of crashing and breaking metal was incessant.

That situation was comparable to the end of the world, and Mamba was a little skeptical that if the flood broke through the three layers of defense, the building he was in would be able to hold up at that time.

Soon, the first line of defense was breached, and the flood water mixed with various broken pipes slammed into the second line of defense.

Everyone felt a tremor under their feet, and the shock from the impact had already affected the foundations of the "fortress", and some of the low buildings on the street were even collapsed.

The walls of the metal pipes were vulnerable to the floods, which quickly washed away the second layer of defense, and now only the inner layer of defense is still struggling to support.

"Click, click, click......" The ground around the "fortress" began to flip around the "fortress" amid the sound of a string of gears turning.

The ground that had been flat was all twisted into a vertical state, and the houses and buildings on the ground fell into the endless abyss.

This is the final solution for the upper floors of the "fortress", opening the guardrail and allowing the flood to drain into the next level of space, just so much flood is also a catastrophe for the lower level.

Dead friends don't die poor, and now the "fortress" can't care so much.

"Bang!!" The last layer of defense was finally in jeopardy, and the flood quickly broke through a gap, and the flood peak with various building fragments finally reached the inner layer of the "fortress".

The howling flood water crashed against the guardrail, and instead of rushing into the interior of the "fortress", they fell down the diversion channel into the downward passage.

The huge transparent passage that connects to the next floor is like a bottomless deep hole, and no matter how much flood water fills it, it does not make a splash.

It was as if the flood had found a funnel and had all of it drilled into it.

The flood came and went as fast as it came, and it took almost an hour for all the water to drain to the next level, leaving only a large pile of mud and crumbling construction debris around the "fortress".

Seeing the power of the flood with their own eyes surprised the members of the expedition, and it seemed that the flood that hit the gathering place was only a small part of it, otherwise the remaining members would definitely not have a chance to survive to inform them.

Mamie and Ena, who are familiar with the spiritual network, immediately inform Fran of what happened in the "fortress".

This is also the code of conduct that they set after receiving the oracle, and no matter what happens, they must maintain an hourly exchange of consciousness.

Although such communication consumes a certain amount of mental activity, with the support of the spiritual network, these costs are well within a tolerable range.

"You ...... Without your advance notice, the entire 'fortress' could have been completely destroyed in this flood! Muki, who had been stunned all along, finally came back to his senses, and he shook Mamba's hand with great excitement and said.

Mamba smiled: "We are all residents of the same floor, and the importance of the 'fortress' is self-evident to us, which is what we should have done. ”

As he spoke, he looked at the time: "Well, Mr. Torre doesn't know if he will come back tonight, or let's go back first, and visit next time." ”

After this flood, the situation in the gathering place is not optimistic, and Mamba is now impatient to rush back.

"Wait a minute! Mr. Mamba! The elevator door opened, and Torre hurried over with someone:

"Mr. Mamba, this time it is really thanks to your early warning that the 'fortress' can be saved at such a small price, and the 'fortress council' has asked me to take you over and express my gratitude to you in person."
