Su Ran carefully began to dissect the whale's body with the dagger he carried with him.

As his movements gradually went deeper, the whale's skin was cut open bit by bit, revealing its internal structure.

During this process, he noticed that a large amount of gas accumulated in the whale's body was slowly being released.

"It looks like the gas in the whale's body is gradually being discharged."

Su Ran secretly rejoiced in his heart, as this meant that the risk of the whale carcass exploding had been greatly reduced.

However, Su Ran did not relax his vigilance.

He knew that although the current situation seemed relatively stable, any small negligence could lead to unpredictable consequences.

"The gas is being discharged continuously, but we still need to stay highly focused and cautious and continue to carefully inspect the whale's body."

"After all, with such a big creature, if you are not careful, it will cause irreversible consequences."

During the dissection process, Su Ran discovered that the whale's internal organs were extremely complex, with each organ closely connected, as if forming a sophisticated biological machine.

One can't help but feel awe at the magic of nature and the mystery of life.

At this moment, the audience in the live broadcast room was very curious.

"Brother Su, whales and dolphins both breathe with lungs, but they can't stay underwater forever like fish. They have to surface to breathe. Does that mean whales can survive on land?"

"It's hard to say. Is it possible that whales were once land mammals?"

Seeing the audience so curious, Su Ran nodded and said, "Yes, the ancestor of whales is a land mammal that lived about 5000 million years ago, called the Pakistani whale."

"Pakistani whales were small, similar in size to wolves, with long legs and clawed toes. Their ears and nostrils were located on the top of their heads, suggesting they were a semi-aquatic mammal."

"There were several transitional types between Pakicetus and modern whales. One of them was a mammal called Ambulocetus."

The amphibian that Su Ran mentioned lived about 4900 million years ago. It was similar in size to a dolphin, with a powerful tail and long limbs.

Another transitional type is Rodhocetus, which lived about 4700 million years ago and already had a streamlined body and shorter limbs, making it better suited for living in water.

Due to historical reasons, the ancestors of whales have fully adapted to life in water. In this process, their hind limbs gradually degenerated, their forelimbs became fin-shaped, and their tails became large to adapt to the needs of swimming.

As for their noses, they have moved to the back, forming a breathing hole, which makes it easier for them to breathe underwater.

Hearing and vision abilities have also been enhanced to adapt to underwater environments.

"The evolution of whales to their current form is entirely the result of evolution. As you said, is it possible for them to return to land? In theory, it is possible."

The audience didn't expect it to actually work, after all, they were just talking nonsense.

Su Ran laughed and said, "What I said may just be a theoretical possibility that cannot be realized. Unless whales can grow legs and their bones become stronger, only if these two conditions are met can they survive on land."

Some netizens may not understand what Su Ran said, so he simply explained: "Think about it, if a dolphin or whale is stranded on the beach, it will slowly suffocate to death."

"This is because its lungs are located between the heart and liver below the spine and are unable to breathe due to the enormous pressure, which far exceeds the pressure in the water."

"Similarly, if a person's chest cavity is under great pressure, the lungs will not be able to expand, and normal breathing and physiological activities will not be possible. The person will slowly lose consciousness and suffocate to death."

"So if whales want to survive on land, they need bones that are strong enough to support their internal organs from being compressed, and legs to move around on land."

After a period of hard work, Su Ran finally completed the dissection of the whale carcass.

He breathed a sigh of relief and felt an unprecedented sense of accomplishment. "Okay, now the gas in the whale's body has been completely released, and we can proceed to the next step safely."

Now Su Ran has made it so that the stranded whale is no longer likely to explode, so he has handed over the follow-up work to some local staff.

This can be considered as some good deeds he can do before he officially prepares to leave.

Su Ran took the train from Xiong Country back to Linhai, and the snow scene along the way disappeared little by little.

As the train moved away, the white snowflakes that once covered the ground gradually became scarce and eventually disappeared from sight.

Su Ran couldn't help feeling a little lost and melancholy, because those beautiful snow scenes were once one of the most intoxicating scenery in his journey.

On the train, Su Ran recalled the time he spent in Bear Country.

He once strolled along the snow-covered streets, feeling the gentle touch of falling snow.

Each snowflake is a masterpiece of nature. They dance in the air and eventually fall to the ground, forming a thick layer of white snow.

Su Ran often stopped, looked up at the sky and admired the flying snowflakes.

"Su Ran, look outside."

Chen Sisi pointed out the window.

Su Ran looked out the window and saw the mountains and trees in the distance. A group of migratory birds were also flying along with the train.

After an unknown amount of time, Su Ran stood outside his grandfather's yard.

"grandfather!"

Su Ran called out softly, and the old man rushed out of the room excitedly.

"Xiaoran, you're finally back. Grandpa missed you so much."

The old man held his grandson's head with endless longing on his face.

At this time, Mantou and Dahei also rushed out.

The two little guys hadn't seen Su Ran for a while, and they both jumped directly towards him.

The chubby bun jumped onto Su Ran, which made Su Ran feel surprised and happy.

Su Ran gently stroked Mantou's body, feeling its soft and warm touch. Mantou gently grasped Su Ran's hand with his small claws, as if responding to his caress.

Su Ran held the steamed bun in her arms and looked at it carefully.

It is obvious that Mantou is well taken care of by his grandfather. His fur is soft and smooth, like a layer of fine silk covering his body.

Su Ran couldn't help but gently play with the bun's hair, feeling its softness and.

Mantou also sniffed Su Ran's scent with its little nose, and then licked his hand with its tongue.

Su Ran felt an itch: "You, it's been so long, and you still haven't changed this bad habit."

Especially now that the buns are bigger, the thorns on the tongue have become slightly harder, and when I lick myself, I feel an itchy feeling. (End of this chapter)
