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

The base upgrade also brings a lot of technological progress. For example, you can spend crystal cores and certain materials to exchange for technologies such as plasma handheld cannons, small laser transmitters, and rpk air cannons. Sumu still needs to explore slowly!

It is now February in the Gregorian calendar, and we are located in the Arctic Circle, but the weather is not below zero, but has risen a bit.

Su Mu keenly felt that something was wrong, but he didn't know where the problem lay.

He had never heard of the materials needed to upgrade the base again, so he had to keep it in his mind for the time being. There must be a road before the car reaches the mountain, and he might encounter it somewhere!

"Wuhu~"

At this moment, Su Mu drove the base vehicle into the Soya Strait and headed directly towards the Japanese country on the opposite side.

As soon as the base vehicle entered the sea, the huge weight broke through the thick ice and sank suddenly.

"Convert into a variety of battleship forms!"

Following Su Mu's order, amidst the mechanical sound of "Kutakacha", a huge warship with a length of more than 200 meters and a width of more than 30 meters, with a very sci-fi shape, floated on the water.

The ship is full of gun ports, equipped with missile launch ports, and even has a platform for helicopters to take off and land. It is very similar to the Zumwalt-class destroyer of the United States!

The battleship adopts a single fully-enclosed transship structure, which greatly reduces the radar reflection area. Coupled with the [Chameleon's Camouflage Paint] and the [Mirage] attached to the Cloud-spotted Clam, it directly turns it into a real sea ghost!

Seeing the sci-fi appearance of his battleship, Su Mu was very satisfied. Suddenly he thought of the word "various". Could it be that it could transform into other types of ships?

Sensing Sumu's thoughts, the shape of the battleship changed again. A moment later, a nuclear-powered aircraft carrier that was almost identical to the "Vinson" stood on the sea!

It turns out that this is what "various" means!

Su Mu was so happy that he tried out all the classic ships in his memory, including the concept ships he had seen online and the old-fashioned pirate ships from hundreds of years ago. The ever-changing warships could be perfectly displayed!

The base does have its own stable space. No matter what shape and size it changes, the buildings, factories, and farms inside will still be the same, and they will have no impact on the people working inside!

When Su Mu got tired of playing around, he turned the battleship into the appearance of the "North Wind God" nuclear-powered submarine and dived into the sea.

The sea is covered with thick ice, so it is easier to drive under the sea.

Due to the frozen ice and snow cover, it was pitch black under the surface and nothing could be seen.

However, the ship's advanced sonar system accurately fed back the detected images to the screen in front of Su Mu, and it was also a 3D image!

Perhaps it was due to the long period of ice, the lack of oxygen in the sea, and the darkness and silence all around. Sumu didn't touch a single fish along the way.

Suddenly, a little bit of green fluorescence lit up in front, and strips of kelp-like plants were drifting with the waves in the seawater, and the fluorescence was emitted from there.

Su Mu was about to control the submarine to go around, but he didn't expect that the kelp in front was densely packed, forming a large net, completely blocking the submarine's way, and even extending up to the ice surface and hanging down to the bottom of the sea!

interesting!

Su Mu sneered, what the hell, do you still want to trap me?

A window quietly opened at the front of the submarine, and a huge bubble shot out from the dark muzzle, rushing towards the kelp net.

This is an electronic pulse sonic cannon, which appeared in the old movie "The Incredible Hulk" decades ago. The powerful ultrasonic waves brought great trouble to the Hulk!

In sea water, this sonic weapon should be very useful!

The bubbles hit the kelp net, causing the fluorescence to tremble continuously. Hundreds of kelp suddenly turned into powder, revealing a large hole of nearly 100 meters!

The submarine sonar received a special sound wave. I wonder if it was the scream of pain from this kind of monster!

"Hmph, over your own strength!"

Seeing the kelp in other places drifting with the waves like dead snakes, Su Mu breathed a sigh of relief.

It seems that this thing is some kind of mutated plant that grows in the sea. It relies on fluorescence to attract prey and then trap them in a net. Its strength is only that high!

The submarine had just passed through the big hole and entered the depths of the kelp net. Unexpectedly, the kelp that had been very calm just now suddenly seemed to come alive, extending its tentacles to wrap around the submarine.

Su Mu was startled and quickly speeded up, but it was too late. Countless kelp quickly wrapped the submarine tightly, like a rice dumpling!

The force of these kelp entanglements was so great that Le's submarine's electromagnetic defense shield "sizzled" and the indicator lights in the main control room flickered on and off.

Qin Keer was busy in the laboratory, and Li Jingxuan, who was staying next to him, immediately screamed and threw herself into Su Mu's arms.

Lao Mo glanced at her with disdain, still lying on the sofa calmly.

"Will you still pretend to be dead and lie?"

Su Mu patted Li Jingxuan's butt and asked her to leave. He didn't take this level of attack seriously, but was a little surprised that this plant could also use tactics!

A blue light flashed from the outside of the submarine, and the layers of kelp wrapped around it broke apart and turned into coke.

Even in water, ultra-high voltage current works very well!

The rest of the kelp tentacles retracted quickly as if they had touched the palm of a red-hot iron, and the entire sea area became clean in an instant.

"It's not that easy to run away!"

Su Mu was not the kind of master who suffered easily. He snorted coldly and drove the submarine somewhere ahead.

He could see clearly on the screen that countless kelp-like tentacles retracted into a small canyon on the seabed.

Several depth charges were launched. These were the trophies Su Mu obtained from collecting the warships of Milu Guo and Mao Xiong. There were still many in the ammunition depot.

The depth charge slowly fell into the small canyon and exploded instantly. The strong air waves generated caused chaos in the surrounding seawater, and the rocks on the seabed were also shaken to pieces!

"Great!"

Li Jingxuan excitedly waved her fists and cheered, "Now we can kill that monster!"

"not yet!"

Su Mu stared closely at the screen. Under the huge power of the depth charges, countless kelp tentacles hiding in the submarine canyons broke inch by inch. That special sound wave appeared again, like a vicious curse and roar of pain!

"Rumble..."

Before he finished speaking, after a violent shaking, the rocks deep in the submarine canyon were shaken and rolled, and a huge shadow slowly emerged.

This shadow is like a mess of seaweed gathered together. Countless kelp-like tentacles are constantly stretching and contracting, emitting bursts of special "squeaking" sound waves, which is frightening.

"Just come out!"

Su Mu laughed evilly, and two torpedoes were immediately launched, bringing a series of bubbles quickly towards the shadow.

This is the L-65 super-large torpedo produced by Mao Xiong. It has a charge of 1000 kilograms and a speed of 50 knots. It is usually used to attack aircraft carriers and large surface warships!

The shadow saw two dark things approaching, and without thinking, it stretched out its tentacles to wrap around them.

After two huge explosions, the black shadow was torn apart, and countless fragments of branches were floating in the sea water!
