Then the group followed Professor Yan in the sales area while listening to the introduction of various soul beast eggs.

While choosing the soul pet egg you like.

Professor Yan's tone was kind, without any professor's airs, and he was very detailed.

The history of many soul beasts can be described one by one, the future growth direction of various soul pet eggs, how to cultivate soul masters, how to improve the intimacy between both parties, etc., are extremely detailed.

He is very knowledgeable. Sometimes he is even more witty, making everyone laugh.

Soon, everyone chose the same choice.

"Professor Yan, say it seriously." Wang Che suddenly said, "Do you think the green caterpillar has no potential?"

Professor Yan smiled and said, "Theory, no."

The last two simple words seem to negate everything.

The green caterpillar on Wang Che's chest suddenly looked at Professor Yan with some restlessness.

Wang Che immediately touched the little guy's head, which made him quiet, stared at Professor Yan with his big eyes.

"It is very intelligent and enlightened." Professor Yan glanced at the green caterpillar in surprise, "It means that your soul power is slightly stronger than that of ordinary people."

"However, the green caterpillar has a low racial potential. The racial potential is the result of countless scientific researchers studying the evolution and growth laws of soul beasts over the years. There will be basically no big changes, especially the soul pets like green caterpillars."

"You have also learned the basic theory of soul beast evolution in high school. The green caterpillar in the form of soul pet will evolve into a green butterfly when it cultivates its cultivation to about ten years."

"The Green Butterfly is its final evolutionary form at present. The Green Butterfly race has a low potential. It is about two hundred, and according to the acquired cultivation, the up and down fluctuations will not exceed ten points. There is basically no big difference."

Speaking of this, Professor Yan paused and said:

"I can also tell you a piece of news that even colleges may not know. Green caterpillars can mutate and evolve. In the Mingdu War Zone, a special example has appeared in recent years. A martial soul is a soul tyrant from the Spirit Tree. When signing the soul deed for the second time, he chose a wild green caterpillars with a cultivation level of three thousand years."

"Later, because of the special power of the martial soul of the Yanling Tree, it combined with this wild green caterpillar, it mutated and evolved into the Yanling Worm King. The dual-type soul pet, in addition to its own insect system, also became the spiritual soul pet."

When everyone heard this, they exclaimed in surprise.

Spiritual soul pet.

Among many other soul pets, the spiritual soul pet is one of the special and powerful ones.

Basically, most of the spiritual soul pets are not weak.

"This new type of soul pet, research news from the Mingdu War Zone, has a racial potential of up to 42. Among the rare soul pets, they are all middle and upper reaches."

Professor Yan shook his head slightly, "It's a pity that after learning about this news in the other war zones, there were also soul tyrants from the martial soul of the Yanling Tree. They found a green caterpillar with three thousand years of cultivation in the wild, but they did not change after signing the Life Soul Contract with him... The specific reasons for the mutation and evolution are unknown."

"Besides, it is quite difficult to find a green caterpillar with three thousand years of cultivation in the wild. You cannot awaken to the martial soul of the Yanling Tree." Because the martial soul of the Yanling Tree was inherited from the Mingdu War Zone, there are only a handful of them in our Donghua War Zone..."

The stories told by professor-level figures made everyone relish.

These news are relatively secret, so the school will naturally not know.

"In addition to the conditions of the martial soul of the Spirit Tree, the soul master may have used other methods that we don't know. We guessed that it is related to food." Professor Yan said slowly, "After all, the evolution of soul pets is a topic that has been studied in the cutting-edge soul pet science community today."

These words made Wang Che feel very interesting.

"So, there is really no possibility?" Xu Haifeng, who was standing beside him, couldn't help asking.

Professor Yan smiled and asked back: "What is the most basic rule in modern soul pet learning?"

"Evolution is the only way for soul pets to break through life form." A classmate replied.

"That's right." Professor Yan nodded slightly, "So, what are the two most critical factors in the evolution of soul pets?"

"Martial soul and cultivation." Another classmate replied subconsciously.

This is the knowledge learned from high school soul pets.

"Yes, martial soul and cultivation." Professor Yan sighed, "Any evolutionary route is formed around two factors here. I believe you all know a little about normal cultivation evolution."

"The green caterpillar has been cultivating for ten years and evolved into the green butterfly; the Gugubi has been cultivating for thirty years and evolved into the Gumingbird, and the Wind Guling Spirit for sixty years and evolved into the Wind Guling Spirit; the Hundred Flower Beast has been cultivating for seventy years and evolved into the Thousand Face Flowers for one hundred and forty years and evolved into the Flower Fairy; the Young Feathered Eagle has been cultivating for two hundred years and evolved into the Winged Eagle, etc...."

"The mutation and evolution are related to martial souls. The soul beasts in ancient times only evolved through this way. The probability of slaughtering humans and obtaining martial souls is still very low."

Professor Yan glanced at Wang Che, "The upper limit of green caterpillars is very low, and the mutation evolution, you don't have the factors in it."

Professor Yan said this and did not continue.

The students understand everything.

Wang Che pondered for a moment and asked, "What if so, what if the green caterpillars are cultivated to a higher level?"

"How tall?" Professor Yan asked with a smile.

"Million years." Wang Che said the number he had the greatest recognition in his memory for 18 years in this life.

Everyone was silent.

Professor Yan was also stunned for a long time.

Perhaps I was shocked by the answer given by Wang Che.

Professor Yan was silent for a while, without answering directly. Instead, he asked slowly:

"Do you know why, modern times, we define the cultivation strength of the soul pet based on the years?"

This knowledge is very remote.

More than a dozen other students couldn't answer.

"Because in ancient times, the strength and cultivation of most soul beasts was basically equivalent to their lifespan." Wang Che replied, "The upper limit of lifespan is also the upper limit of soul beasts' cultivation."

"That's right." Professor Yan smiled, "It takes a long time for the soul beasts of ancient times to open up the spiritual intelligence equivalent to humans. Most of the time, soul beasts can only passively absorb the soul power between heaven and earth for a long time. They cannot awaken their martial souls and cultivate their soul power like humans."

"So, their lifespan is linked to their age. The longer they live, the stronger their strength."

"A million years is a limit. It is the limit of the soul beasts of ancient times. Even if this kind of soul beast has not lived to a million years, it has lived for at least hundreds of thousands of years. But do you know how many soul beasts of this level were there in ancient times?"

Wang Che shook his head slightly, I really don’t know.

The school’s knowledge includes the concept of a million-year soul beast, and there are also examples.

But the specific information is not.

Professor Yan spread one palm and compared a cross.

"There are about a hundred known ones." Professor Yan said without giving them a guess, "After the disaster of three thousand years, there are only about ten descendants who survived. In other words, if there is no life soul contract, theoretically, in the whole world, there are only these ten kinds of soul beasts that can cultivate to the limit of millions of years."
