"If the aliens you describe refer to intelligent life forms born outside the earth," Gracua paused and said, "then I would be more consistent with this category."

Bai Lin didn't expect that Gracua would make a cold joke and look at him with strange eyes, but he knew that Gracua would reveal to him the ultimate secret of the wizarding world.

Sure enough, Gracua took a sip of the liquid in the cup and continued: "Does Mr. Bai Lin know about mitochondria? They are the mitochondria in humans and most eukaryotic cells."

Bai Lin nodded, and Gracua continued the popular science: "The earth is a very special existence in the universe. It is rich in a poisonous gas that most life forms in the universe cannot adapt to - oxygen."

"Bacteria, the first biological cells born on the earth, are also difficult to survive in oxygen. It was at that time that the earth was discovered by our Lord and the New God at the same time. It was our Lord who gave the earth the ability to give birth to more advanced organisms, and also It’s the mitochondria.”

When Bai Lin heard this, his jaw almost dropped to the ground. After all, he was once a serious college student. Naturally, he still remembered a lot of high school biology knowledge. He naturally understood the role of mitochondria. Mitochondria are like a The engine takes in oxygen and "fuel" from the surrounding cell fluid, allows them to "burn" inside, and uses the chemical energy obtained to power all energy-requiring activities in the cell.

Each cell in the human body has an average of 1000 to 2000 mitochondria. Each cell in extremely energy-consuming tissues (such as the heart, brain, and retina) has a mitochondria (some ovarian cells in women even have 10 mitochondria). .

But mitochondria are not part of ordinary cells, but another type of cell that is parasitic in the cell and forms a symbiotic relationship with the cell. There are different opinions about their origin, and there is no conclusion yet.

After listening to Grakua's words, Bai Lin felt that it was very credible, because mitochondria are a kind of parasitic cells, which are very similar to the abilities of these minions of the ancient gods, and the abilities of the ancient gods also made Bai Lin more profound from this story. I have experienced it.

Of course, the ancient gods would not be so kind as to selflessly "help" the earth to give birth to more advanced life forms. However, 15 billion years ago, there were only a small number of bacterial life forms on the earth. The ancient gods wanted to control the creatures on the earth. The only way to "invade" the earth is to deal with bacteria.

"Mitochondria" is like a biochemical weapon. After invading the earth, it combines with the earth's original life forms to generate new organisms that can adapt to the oxygen environment. Just like the "Yellow Seal" of Hastur Church today, it is aimed at today's life. The main life form on the earth - biochemical weapons customized by humans.

However, the Ancient God's "mitochondria invasion plan" failed to work at a critical moment, and the Ancient God almost lost control of the mitochondria.

Bai Lin suddenly figured it out and laughed: "I didn't expect that the dignified ancient god also got into the business of making wedding clothes for others, haha!"

Grakua's face was a little ugly, but he recovered quickly. He kept his grace and said: "Indeed, our Lord did not expect that the earth's star soul, which was paid special attention to by the Ten Thousand Realms Life Tree Array, could give birth to advanced life so quickly. The body... never expected that the New God would attack the earth so quickly and bring about a disgusting order."

Grakua's expression of gnashing his teeth in hatred made Bai Lin want to laugh even more, but he was still trying to digest the information.

"How much does Sir Bai Lin know about souls?" Gracua asked.

Bai Lin didn't expect Grakua to ask such a question, but he still replied: "Dongfang has a deep study on the soul. We call the three souls: Fei Guang, Shuang Ling and Ghost Essence, which are human beings." Essence, Qi, and Shen are spirits that can transcend the outside of the body. The seven souls are: Corpse Dog, Fu Ya, Bird Yin, Swallowing Thief, Non-Poison, Eliminating Filth, and Smelly Lung, which are human happiness, anger, sorrow, and joy. , Resentment, sadness, and worry are spirits that need to be attached to the human body to exist."

Gracua nodded and said: "Human beings are indeed special. Even without any explanation left by the gods, they can explore to this point... Yes! That's right, these three souls and seven souls are the work of the New God. Among millions of Years ago, the New Gods selected the life forms with the greatest potential on Earth, and based on their own spiritual templates, they created soul templates for these life forms on Earth."

Bai Lin's head was agitated, and he couldn't help blurting out: "You mean, more than one soul model was created at that time?"

Gracua's eyes were surprised. He didn't expect Bai Lin to guess this level. He nodded and said: "As you guessed, the number of souls of the new gods far exceeds the range of three souls and seven souls, but they also do not They didn’t know what kind of soul model was most suitable for life on earth, so they cast several versions from few to many, and experienced several failures..."

Gracua suddenly laughed heartily and said: "Poor humans, they still think that the new god is the incarnation of justice and light. Hahahaha, it really makes me laugh to death!"

Bai Lin's face turned a little pale. He thought of the several mass extinctions in the history of the earth. If what Gracua said was true, those mass extinction events were probably the result of the New God experimenting with life on earth and injecting these " The result of "Soul Template", for example, the mass extinction of the dinosaurs in the Cretaceous period 6500 million years ago. If the New Gods came to the earth at that time, the dinosaurs would certainly be the most potential life forms at that time.

As for why humans were born and developed, it was just a coincidence that the mental power of the ancient ape was just right for the soul model of "Three Souls and Seven Souls", and he became a survivor of the New God Soul Testing Ground.

"You should have guessed it, so I won't explain more. Hahahaha, do you think this is the end? No! The New God discovered that the human species can adapt to three souls and seven souls. Will it be able to adapt to other models? What? So they did many experiments on humans...such as four souls and five souls, and finally dementors were born...such as three souls and eight souls...which were later called wizards..." Gracua said the last word The way.

Bai Lin took a deep breath, and everything made sense. In the world of the gods, human beings have always been just pawns on a chessboard. As the saying goes, the world is unkind and treats all things as suckers, suckers and suckers. Naturally, there is no difference. Humans are not a race that is particularly favored by the gods. They are just ordinary ants in the yard.

"Ouch!" With a sound, Bai Lin suddenly stood up, moved his wrists and shoulders and said, "I've finished asking my questions, and we can talk about business... You mean you can't use extraordinary power here, right?"

"Eh?" Gracua was a little confused by Bai Lin's question and didn't know what he meant.

"I mean, in addition to my extraordinary strength, I also know a little bit about boxing..." Bai Lin smiled brightly at Grakuya.
