Hearing this sound, a bad premonition appeared in Duan Fei's heart, although the voice was different, but it sounded the same as the emergency alarm in Yanhuang City.

Sure enough, as Duan Fei expected, Zhang Hongyi at this time stopped chatting with Duan Fei, and hurriedly turned on the communicator and asked anxiously, "What's wrong?" There is an invasion of foreign enemies? ”

"There are no foreign enemies! The data shows that it is strange that the sea water swelling two kilometers outside the outpost island is abnormal, and! Speaking of this, the voice on the other side of the communicator could be clearly heard, and the communicator was also very confused.

"What's going on? What's out of the ordinary? Hearing this, Duan Fei naturally leaned over to hear what was going on.

"Nautical mile...... Evacuate and go back to shore! Fast! As if suddenly seeing some special data, the communications staff suddenly shouted in alarm, and soon there was a rustling noise in the communication channel, and it was no longer possible to hear what was being said on the other side.

Skynet uses radio communication, and unless the surrounding space is enclosed or the distance is too far to receive the signal, this kind of communication will not occur.

But now the island is surrounded by the sea, and it is not far from the base on the cliff, how can this signal be broken?

"Brother Duan Fei, please tell the recruit corps to come back quickly, and I will start the island defense!" Thank you! As soon as Zhang Hong said a word to Duan Fei, he ran directly towards the control room of the training ground.

Although I don't know what happened, I also know that it's not good, this island plays a pivotal role in the Eastern Branch, and it is also the first line of defense to guard the sea surface of the Skynet Branch. Since the communication center mentioned that there was an anomaly in the ocean before the call was interrupted, it was correct to turn on the island defense system.

Flying towards the recruit regiment that was still swimming wildly, Duan Fei, who was suspended on the water, shouted loudly to the recruits, "There is an abnormality in the sea, go ashore and go back!" ”

"Where's Instructor Zhang?" A boy asked in the water.

"He went to turn on the defense! Don't talk so much! Go back! After saying that, he flew up to the base on the cliff, the sea level line of the island is not high, which makes it difficult to observe the situation at sea, as the saying goes, stand high and see far, this is the best proof.

Duan Fei, who was above the eastern branch of the mountain cliff, glanced around at the situation on the sea, and at this moment, on the marginal line far away from the sea, a white sea line several hundred meters long appeared on the water.

This is...... Tsunami?!

Duan Fei had seen a large-scale tsunami attack in his previous life, which directly swallowed a beach city and hit the sea, and the huge waves instantly washed away dozens of buildings near the coast, and then submerged the entire city, leaving only some of the half-tall buildings.

Under the tsunami, the impact on the small island is the greatest, and it is possible to turn it into an island under the sea. That's why Zhang Hongyi rushed back to turn on the defense system in such a hurry.

With the experience of the two lifetimes, Duan Fei felt that there was something hidden under the tsunami, and it was its appearance that led to the appearance of the tsunami, and once the waves were too big and the small island was submerged, the eastern branch base on the cliff completely lost the first line of defense on the sea, and this blow was undoubtedly huge.

Before the establishment of the island outpost, the Skynet organization had sent experts in marine and geological fields to investigate, and this island and mountain cliff on the sea shelf would not be affected by any large-scale marine disasters in the next hundred years, especially natural disasters of the tsunami level.

I didn't think that this reasoning would be interrupted after just a few years of establishment.

And the recruits who swam on the ocean also returned to the base through the hollow shore of the cliff.

The height of the cliff was high enough to withstand the impact of the tsunami, and the Eastern Branch base did not deploy any defenses, except for the waterproof exterior wall to resist the sea water that might splash up.

The surrounding steel walls gradually surrounded the combat training ground, and a large area of plants and buildings also sank, replaced by a large steel outer wall, and within three minutes, a huge all-steel island centered on the central bulge appeared in front of Duan Fei. The outpost is now completely a separate place, isolated from the sea except for a secret passage to the cliff underground.

It has the effect of mitigating the impact of a tsunami, so the hardness of the steel façade covering the island is also unusually high.

"Brother Duan, come in!" At this time, a staff member of the Eastern Branch saw that Duan Fei was still looking at the sea on the outer platform of the observation office, and couldn't help but get up and walk out and say.

"Oh! Don't worry, I have my own plans! "Even in the face of a monster like the Immortal Demon Snake, Duan Fei has never been afraid, then for ordinary natural disasters, Duan Fei will not be afraid of where to go, people who have seen strong winds and waves are naturally more open to some small storms.

From the thin white line of a line to the thickness of a finger and then to the size of an arm, the sea formed a tsunami at a rapid speed, and countless small waves were quickly dispersed as the tsunami was about to rush to the first line of defense on the surface of the Eastern Division.

Touch! The first small wave slammed into the steel island, and soon the second, third, and fourth waves followed.

The steel islands are more than enough to deal with these small waves, and the only real thing that can break through the steel façade is the last mega-tsunami.

Hellfire Shield! Cast!

Quickly forming a two-meter-sized flame shield in front of him, Duan Fei still looked at the tsunami not far away with a calm expression.

At this moment, a looming black shadow passed by in the sea water, and if it weren't for Duan Fei watching the movement of the tsunami, he wouldn't have noticed that there was a black shadow for a moment.

How can there be dark shadows here, could it be that the tsunami brought more than just seawater, but also other things? Or was it the dark shadow that caused the tsunami?

Bumper Bumper! In the next second, a loud crash sounded in the seawater.

Worst!

That thing is crossing the island! The transformed small island is not without its reason and value as the sea defense line of the Eastern Branch Base, first of all, it can isolate some mutant beasts living in the sea, and become a threshold to enter the cliff coast.

If a monster is found to be attacking, the island will launch an artillery attack to force it back or kill it, but now that the island has been fully defended, it is impossible to see if there are monsters outside.

This creates an opportunity for the Sea Mutant Beast.
