After Gaia's reminder, Lin Han also suddenly remembered. Since the other party is from the far reaches of outer space, the microbes in its spacecraft must be very different from those on Earth.

Just like the invasion of plants and animals, microbes can become lawless when they arrive in a new environment, and they are often more destructive.

In the play, modern people wear back to ancient times, and if this happens, the biggest possibility is that the new bacteria that have evolved in modern people will bring disaster to the ancient world.

And there is no doubt that the difference between strange bacteria in distant outer space and bacteria on Earth is better than that of old and new bacteria.

Now the biological authority is unknown to the extraterrestrial creatures, in case of any dangerous bacteria and viruses that run out and are out of control, the consequences are absolutely unimaginable.

Break the physical barrier between aliens and the earth's ecology, and at the same time prevent possible alien bacterial invasion...... It seems a bit tricky.

Not only that, but it must also be kept secret and not let the outside world know.

After all, a team of weak wild aliens are treasures no matter how you look at them. Not to mention anything else, if it can be taken down by an armed spaceship that is amphibious in the air, sea and space, it will definitely be of infinite use.

……

"Wow-"

The thick column of water rose into the sky, but it was a young whale with a body of more than ten meters, wandering in the sea water, churning from time to time.

In terms of characteristics, it appears to be a blue whale, but its skin is metallic silvery-white, full of indestructible heavy texture.

Despite its young size, it makes waves in the water that is no less than any sea creature, and the jets of water that spew out are more like water guns, which looks extremely unusual.

Looking at the young whale that was churning in the water, Lin Han couldn't help but smile.

This young whale is naturally a mutant of the blue whale that he bred in the Arabian Sea before - named "Iron Pillar".

The results of the cultivation did not disappoint him, the strength, speed, and intelligence level of the iron pillar were far superior to those of ordinary blue whales, especially its terrifying power, Lin Han even suspected that this guy would even overturn an aircraft carrier when he grew up.

In fact, it's about to grow.

After returning from the South Pacific, Lin Han gave it more than ten thousand years of vitality, allowing it to come out of the artificial womb directly and return to the sea.

Despite being just born, with the terrifying power of the Iron Pillar, a flick of the tail can break an adult great white shark in two, and there are simply no creatures in the ocean that can threaten it.

After a few days of feeding and the action of life force, the iron pillar grows very rapidly, and it is estimated that in another week, it can grow to 50 meters long, almost twice the average adult blue whale, and weigh more than 20 times.

Lin Han believed that with the escort of this super beast, he could go to the vicinity of the alien spaceship.

"It's lunch, Iron Pillar. He shouted in the right language.

"Moo-" Tiezhu then groaned softly, and quickly swam to the shore in the splash, opening his big mouth and shaking his tail slightly, looking extremely expectant.

This is Lin Han's private island, in eastern New Zealand, which was bought just last year, sometimes for vacation, and sometimes for scientific research in the laboratory.

Now the main use is to feed the iron pillars, and hundreds of tons of fresh fish and shrimp are transported every day.

At this time, several trucks were parked on the shore, and after the rear door opened, a dozen strong men took down one box after another from the truck, walked to the water's edge, and rolled the fish and shrimp into the big mouth of the iron pillar.

At the end, there were several bags of marijuana, which were also thrown in.

The sack contains a "multivitamin and mineral" specially made for the iron pillar, which should be taken after each meal to improve the balance of the diet and promote growth and development......

After feeding, Lin Han took the time to train the iron pillar for a while.

Iron Pillar has a high IQ, and if his anatomy allows, he can even communicate with humans simply through sign language, like some orangutans.

Now, despite his limited ability to express, Tie Zhu's comprehension ability is not bad, and he is able to understand some human words.

Out of consideration for Tie Zhu's comprehension ability, Lin Han used orthodox language when training it. Given the simplicity of the language, it may be a few years before the iron pillar will become the first animal to master a language in its entirety.

While training, Lin Han received a text message on his mobile phone, he picked it up and looked at it, muttered for a moment, and then leaned over and patted Tie Zhu's head: "Go play by yourself, I have to go first." ”

"Moo......" Tiezhu's voice sounded a little unhappy, but he still wagged his tail, and then rolled over and submerged in the water.

Lin Han turned around and left, coming to the biochemical laboratory on the island.

"How's it going, Dr. Zhang, have all the bacteria been chosen?" he said to Dr. Zhang, closing the door casually.

Dr. Zhang lifted his glasses, took out a thumb-sized vial, and said, "There are a total of 33 superbugs, all of which have super survival and reproduction ability, but the pathogenic ability is basically zero. ”

Lin Han took the vial and looked at it, and said with a smile: "Yes, I'm sorry for you." ”

……

Ten days later.

Southern Atlantic, deep sea.

A silvery-white giant whale with a length of nearly 60 meters slowly wandered in the water, and finally docked near a certain reef and opened its mouth.

Lin Han, who was wearing a black diving suit, came out of the mouth of the iron pillar, patted the ground, opened a tunnel, and then walked along the tunnel towards the location of the spaceship......

A few kilometers away from the ship, a two-meter-long cylindrical underwater robot was wandering, its dark blue color was quite indistinguishable in the water.

Looking at it, it seems to be looking for something.

In the middle of the night, a large fat fish approached, and the robot immediately stretched out its mechanical arm to grab the fish and load it to an opening at the bottom.

It turned out to be catching fish......

In this way, the robot caught fish nearby for more than ten minutes, then turned around and turned back, and soon returned to the spaceship.

The entrance to the side of the ship opens, and the robot enters the chamber with the seawater.

Entering the spacecraft, the cabin first drained the seawater, and then the robot unloaded a transparent sealed container through the side opening, filled with large and small fish and shrimp, many of which were still alive.

Bright lights began to emit around the chamber, and after about five minutes, the hatch on the other side opened, and two blue-skinned men entered, carrying the transparent container......
