The world is frozen: I spent a billion dollars to build the strongest safe house

However, the submarine did not go very far south when it encountered a school of sardines.

The radiation detector on the submarine kept flashing. This place is close to Fukushima, where nuclear wastewater is discharged into the sea. Obviously, these sardines with cold green eyes are also the product of radiation mutation.

There were millions of sardines in this group, and Su Mu was unwilling to get entangled with them, so he ordered the submarine to dive in order to get around them.

Su Mu wanted to hide, but the group of sardines didn't want to let him go. They somehow sensed the location of the submarine and swarmed towards it.

Damn it, these nuclear mutated creatures are a bit evil!

The invisibility effect of his base was very powerful, but the big lizard and the group of sardines were able to find his position accurately, which made Su Mu a little depressed.

Is it because they sensed the nuclear power plant under construction in the base?

While Su Mu was thinking, countless sardines had already surrounded the submarine, opening their big mouths full of sharp teeth and biting desperately on the plasma shield.

The strength of these sardines is not high, and they are at the level of ordinary zombies, but there are so many of them that they actually reduce the energy of the plasma shield by a small amount in a moment!

Su Mu snorted coldly and immediately released the ultra-high voltage current.

The powerful current directly ionized the seawater around the shield into gas, and its remaining power continued to spread outward in the seawater. Suddenly, all the sardines within a hundred meters turned up their white bellies!

With just one blow, Sumu reduced the number of this huge sardine group by one-third!

But the rest of the sardines seemed to have not seen it, and still rushed towards the submarine crazily.

Releasing ultra-high voltage current consumes too much energy and cannot be sustained. The submarine stretches out ultrasonic pulse cannons and continuously shoots around.

Every time the ultrasonic pulse cannon is fired, the powerful sound waves shatter the sardines in one direction, revealing a large gap. However, the gap is quickly filled with other sardines, still surrounding the submarine!

Seeing that the energy of the plasma shield was decreasing, Su Mu had no choice but to release the ultra-high voltage current again.

After continuous powerful attacks, the sardine school finally became much thinner, with only less than a million remaining, but they still refused to let go and attacked the submarine desperately!

Not knowing what went crazy with these sardines, Su Mu was helpless and had no choice but to turn on the power of the plasma shield to the maximum.

Depth bombs, torpedoes, ultrasonic pulse cannons and other weapons were used in turn, trying their best to kill these crazy mutant fish. There were pieces of mutated sardine corpses floating in the sea water.

Seeing that only half of the energy of the plasma shield was left, suddenly these sardines seemed to have received some kind of signal and stopped attacking, turning their heads and swimming quickly into the deep sea.

Although Su Mu didn't know what happened, he breathed a sigh of relief.

There are too many of these sardines. If you continue to struggle like this, even if you eliminate them, the energy of the plasma shield will be reduced to a very low level.

This battle was really inexplicable, and Su Mu was very depressed!

He sent an underwater robot to pull a trawl net, bring the sardine carcasses back to the submarine, put them into the garbage conversion processor, and at least recover some interest first.

[Ding: Transform and process the carcasses of one million nuclear mutated sardines, increase the energy of the base by 10, and isolate one kilogram of uranium-235 raw material! 】

Su Mu's eyes lit up. Uranium raw materials were what he needed most. He didn't expect that these sardine carcasses could be extracted. He quickly ordered the underwater robot to seize the opportunity to catch them.

Suddenly a huge black shadow rushed over like a ghost, opened its big mouth and swallowed several underwater robots together with the sardines in the trawl net.

"Haifu!"

Su Mu immediately recognized the sudden appearance of the monster, with a solemn look on his face.

The sea turtle looks somewhat similar to a large shark, more than thirty meters long, with a big mouth that takes up about a quarter of its body, filled with dagger-like teeth, and its fins are covered with countless inverted The hook is frightening at first sight.

It was only when those sardines felt the breath of the sea that they stopped attacking the submarine and fled in panic.

I don’t know what kind of changes happened in the Japanese country, and this legendary monster appeared again!

The sea turtle swam nimbly in the sea water, constantly devouring the corpses of electrocuted sardines.

Su Mu suddenly became anxious, aren't you trying to steal uranium raw materials from me? How could you bear this? He immediately fired an ultrasonic pulse cannon at it.

Hai Fu, who was happily eating, was caught off guard and received such a blow. His head suddenly became dizzy, and green blood continued to overflow from his cheeks.

Hai Fu was furious and shook his head. Like a huge torpedo, he opened his mouth and rushed towards the submarine at high speed.

This huge monster was easier to deal with than a swarm of millions of sardines. Su Mu was not afraid, and aimed the ultrasonic pulse cannon at Hai Fu and fired again.

Although Hai Fu's body was large, he was extremely flexible and managed to avoid the air bubble with a flick of his tail.

It quickly swam to the side of the submarine, raised its huge tail and slapped it hard on the plasma shield, and then its barbed dorsal fin scratched across the shield, causing bursts of sparks!

The plasma shield was directly hit by Hai Fu's tail, making a huge dent. It kept shaking violently, and its energy was suddenly reduced by one-third. The indicator lights in the main control room kept flashing!

The attack power of this big shark is so high!

Su Mu was a little surprised, but not much worried.

His submarine is made of a special alloy with astonishing hardness. Even if this sea creature can break through the plasma shield, its big teeth will be knocked off!

Seeing Hai Fu turn around again, he opened his big mouth and quickly bit into the submarine. A huge special fishing net was instantly launched from the submarine, and its head was lifted towards Hai Fu.

The two were so close that Haifu couldn't dodge and was immediately covered by the big net.

The big net is connected to a metal rope, and a blue light flashes on it, and the ultra-high-voltage current is transmitted along the rope!

Haifu's body froze, and his outer skin was scorched black by the electricity, and some places were even directly carbonized!

Even in the sea, its high-pitched screams reached the submarine.

The submarine suddenly accelerated forward, and at the same time, a long spiral horn stretched out from the front, instantly piercing Haifu's stiff body!

The ultra-high voltage current was continuously transmitted, and a burst of white smoke came out, immediately electrocuting Haifu's internal organs.

Hai Fu was like a fish stuck on a harpoon. After struggling for a while, it finally stopped moving.

Su Mu took the fishing net wrapped with Haifu's body back into the submarine. Dozens of robots rushed forward and quickly dismembered it, taking out a third-order crystal core that shone with light.

The strength of this Haifu is definitely not that high. Under normal circumstances, even a fleet from the Bad Kingdom may not be able to defeat it!

But when encountering a monster like Su Mu, some skills were killed before he could even use them!
