followed Yi Yun and came to his pig's nest again, but, compared to last time, this time it was much cleaner, for some reason.

"What's the situation, mysterious and secret?" asked Yu Fan after sitting down.

"Do you know the blind end of the side branches?" asked Yun Yun rhetorically.

Yu Fan glanced at Yun Yun, what kind of words, I have never heard of them.

"It's a word related to evolution, and it's normal that you don't understand it. Yun Yun said, pushed his glasses, and began to explain this word in detail for Yu Fan.

In the past, we believed that biological evolution began with lower organisms and evolved from one species to another.

But later it was discovered that once a species is formed, it will never change until it goes to the blind end and goes extinct. The new species is the heresy and lateral branches of the original species that grow on their own, not the transformation of the original species.

For example, the fish species has not changed much for 500 million years, but one side branch of the fish has evolved into a reptile, and another side branch of the reptile has evolved into a mammal.

However, the most dominant dinosaurs among reptiles and Homo erectus among mammals did not undergo any major changes in their survival until they became extinct.

So, the species does not change from formation to extinction until it reaches the blind end, and then a side branch becomes a new species.

This is the blind end of the lateral branch.

"What does this have to do with me?" Yu Fan was puzzled.

Yun Yun waved his hand and motioned for Yu Fan to listen to himself: "Before, I mentioned to you the relationship between cultivators and ordinary people, and it is appropriate to explain it with this theory. Legend has it that Nuwa made people out of the soil. Let's assume that the legend is true. Before Nuwa created man, the human species did not exist, and the existence is also explained in our mythological stories, they are all 'chaos gods'. So, how did people begin to cultivate? There are many opinions on this, but there is no record of it. ”

"Even if the legend is false. By evolutionary standards alone, we humans, from fish to the present, have proved that we were once collateral, that is, weak!"

"Now, we see that there are some capable people in the world, and the vast majority of human beings are unable to cultivate. Why? Because, one of the essences of a cultivator is that the three states are incomplete as I mentioned earlier, which shows the difference between the five elements. And this group of people all have one thing in common, that is, there are many disasters and difficulties, and none of them are smooth sailing. ”

"Then, this group of people, in an environment of survival of the fittest, will inevitably be defeated by ordinary people before they cultivate the truth. In other words, ordinary people are former winners, and those who cultivate truth are former losers. As a result, before this group of people cultivated, they became a side branch of the 'human' race. Then, in the long course of development, took another path. ”

"But after all, only a few people can walk on this road. ”

Yu Fan gave a thumbs up to Yun Yun.

"Say, don't worship brother, brother is just a legend!" Yun Yun looked proud.

"I mean, you can really talk about it!" Yu Fan didn't give face at all, and said: "You talk so much, it still has nothing to do with me." ”

"Don't you think you're the side branch?" Yun Yun's eyes lit up, like a paranoid scholar: "What a rare research opportunity to return to the state of silence." Once the calamity is broken and soars into the sky, if this technique is mastered by us, then it will definitely be a blessing for our generation of cultivators. ”

"Nonsense!" Emotionally, Yu Fan naturally believed what Yun Yun said, as well as his conjectures, but he didn't think that Yun Yun could study anything, after all, the ancestors were so powerful.

Yun Yun smiled, with an expression that knew you didn't believe it, and said, "If I say that we have successfully changed the balance of the three states of the human body, so that an ordinary person can successfully awaken and step into the cultivation realm, do you still think what I said before is nonsense?"

"What?"

"We have used advanced scientific instruments and combined with biological knowledge to do experiments on animals, and the technology is quite successful. Then, we found an ordinary volunteer and successfully awakened him, successfully verifying our conjecture. Yun Yun's face was full of pride.

"Uh...... I forgot to tell you, in fact, my aura has already shown signs of recovery, so I may ......" Yu Fan was a little embarrassed, after all, Yun Yun was really thinking about him.

As a result, before he finished speaking, he heard Yun Yun exclaim: "What?"

Then, grabbing his wrist, his face cloudy.

After a long time, Yun Yun let go of his wrist and smiled: "Congratulations, you have returned from the catastrophe." Sooner or later, you'll soar to the sky. ”

It's just that there is a loss in his eyes that is difficult to hide, and he can't get rid of it.

Yu Fan was about to say something, when he suddenly felt someone behind him, and before he turned around, he felt a pain in his neck and fainted.

"Uncle, what are you doing here?" said Yun Yun urgently.

"Our research, there is no room for any accidents!" Uncle Yun Yun was very majestic, said, picked up Yu Fan, and walked towards the door.

Yun Yun is timid, so among his familiar peers, he often pretends to be bold. But in front of others, especially elders, he was a submissive child, and he didn't dare to speak out, so he had to follow.

......

Zheng Tian Pet Hospital, I don't know who used what great mana, the unruly shops here that were destroyed by the aftermath of the last battle have now recovered as before, as if nothing had happened.

Only the owners of these shops know that it is now classified as a dangerous building by the relevant authorities and will be demolished and rebuilt in the next few days. When it comes to demolition, a large amount of demolition compensation is indispensable, and they are naturally happy with it.

"Whew......"

Suddenly, the cub stood at the door, looking up to the sky and screaming mournfully, his voice was like a cry, and he screamed a few times towards the store, looking very anxious.

Zhongli walked out of the back room in a white coat, and on his shoulder stood a small bird named Cardinal.

"What's wrong?" Zhongli asked.

"Whew...... Woo ...... "The cub was jumping around on the ground, restless.

"Chirp" Cardinal seems to be translating for Zhongli.

"I can understand what it means" Zhongli looked at the cardinal, then at the cub, frowning slightly, "You mean, he's in trouble?"

The cub tilted its head and twitched wildly.

"Where is he?"

"Woo...... the cub turned his head, his front paws raised, and pointed in the direction of the city center.

Zhongli nodded, flipped his hand, and a round crystal ball appeared in his hand, and he said it silently in his mouth, and suddenly, the crystal ball expanded rapidly, like an expanding bubble, spreading towards the surroundings. Touching the wall, objects, all included in it, and not damaged in the slightest.

Then, it disappeared into the air, as if it had never appeared.

"Cardinal, go!"

Hearing the sound, the cardinal flew out of the door, screamed, turned into a big red bird, spread its wings and soared.

Zhongli pulled the cub through the air, jumped on the cardinal's back, and said softly, "Lead the way!"

In this way, a person, a bird, and a dog volleyed away and disappeared in an instant.

As for the pedestrians, they did not notice anything unusual.

Even, the big bird flew through the sky, and the whole city did not notice it in the slightest.
