The carriage was heading towards the Heaven Dou Imperial City, and with a goal, Xiao Ye didn't want to waste time in school.

"Ake, although it is a bit presumptuous, if you can, can you tell me about the evolution of the royal martial spirit?"

The world of the empire was brought down by the royal family, but something must have happened halfway through, so that the powerful martial soul of the Heaven Dou Imperial Family at the beginning evolved into the current "vase" swan martial spirit.

Xue Ke sighed faintly: "This is not a secret. At the beginning of the establishment of Tiandou, the martial soul of the royal family was a very powerful Ice Feather Qingluan, and it was in the generation of my great-emperor that it evolved into a swan. This is a scandal of the royal family, and the specific details are inconvenient to say, and I hope that Brother Ye will forgive me. ”

Xiao Ye nodded: "It's okay, it's good if you can tell me this." Now it can be known that the royal family's swan martial soul is the result of the degradation of the original martial soul. ”

"Then, Ake, let's try to see if we can make your martial soul return to our ancestors."

Xue Ke was willing to be a test subject of Xiao Ye's theory, and Xiao Ye was very happy. Because if you want to prove this theory, the precondition is that the innate soul power is high enough, and the quality of the martial soul is not so good.

For a top-level martial soul like the Blue Electric Tyrannosaurus Rex, people must follow the path explored by their ancestors, and it is impossible to take the risk of trying a new path.

And the problem that the quality of the martial soul is too inferior is even a question of whether it can break through the Soul Sect, let alone the evolution of the attached ring.

Xue Ke is just right, anyway, the swan martial soul is a chicken rib, no matter how it is cultivated, the effect is like that. It's originally a vase, so it's better to gamble, if Xiao Ye's theory is correct, it will make a lot of money.

As for whether Xue Ke has any other thoughts in her heart, it is unknown, anyway, she is willing to cooperate to confirm this fanciful theory.

The Heaven Dou Royal Library is not far from the Prince's East Palace, and the last time you want to come here to consult materials is to be an earl. However, with Xue Ke there, Xiao Ye didn't spend too much tongue to go in.

"I'll take a look, the information of the Dugu family - there!"

Douluo Continent has science and technology, but this technology tree is relatively crooked, mainly in terms of people's livelihood. Xueke uses this kind of thing to determine where the information you want to find is.

Xiao Ye stretched out his hand, and with a bend of his five fingers, a thick book flew out of the shelf.

This is his self-created soul skill sucking palm, and its idea is a control skill that can pull the soul master directly over. However, the goose has beautiful ideas, and the reality is very skinny, and at present, Xiao Ye can only pull some small things.

For example, the stones on the road and the books on the shelves, Rao is like this, this understatement also made him pretend to be in front of Xue Ke, and the little girl's eyes full of adoration made Xiao Ye's vanity very satisfied.

"The History of the Dugu Family" - this is the name of the book.

Open the catalog, it is the introduction of the patriarchs of the Dugu family, the catalog is very detailed, what is the martial soul, how many levels are in the end, and the details are determined on the first few pages.

Glancing at the general situation, Xiao Ye smiled: "Ah Ke, if you look at the development of the Dugu family's emerald scale snake, you can clearly deduce that the emerald scale snake emperor under the Dugu crown is an atavistic phenomenon. ”

Xiao Ye pointed to the names of several of them, all of whom were strong at level seventy or above.

Carefully, put the ruby-like soul guide that can scan and store the contents of the book on the book, and as soon as the light flashed, a page appeared, and Xiao Ye clicked a few times, leaving a few pages of text floating in the air.

Named the "Red Book" by him, this soul guide is able to store book information and generate models.

Xiao Ye put his hands behind his back, looked at these data materials, and a smile appeared on his face: "Sure enough, it is similar to what I guessed, the soul ring can indeed promote the evolution of martial souls." ”

"Ake, you see, Dugu Ye is the first person in the Dugu family to have the Martial Soul of the Emerald Snake Emperor, and several of his key soul rings are taken from the hundred-year-old green bamboo green, the thousand-year-old mandala snake and the 10,000-year-old Medusa, which are the best of the snake martial souls."

As he spoke, Xiao Ye adjusted the Red Book, only to see a large number of phantoms of snake soul beasts floating in the air.

The first thing that can be deduced is that the soul ring of the same kind of soul beast can indeed promote the growth of martial souls, and the key lies in this.

Xiao Ye was a little bit, and the green bamboo green, the mandala snake and the blue scale snake and Medusa's soul beast illustrated book appeared.

"The mandal snake can evolve into Medusa, and the green bamboo green can evolve into the emerald scale snake, but these snakes all have the same ancestor, which is the black-faced golden-ringed python."

"We can see that Duguye's thousand-year soul ring and 10,000-year soul ring are respectively taken from soul beasts with strong blood relatives in the same martial soul category."

"Not only Dugu Ye, Dugu Xing Er, Dugu Susu, including the current Dugu Crown, all have the same match in the soul ring. We can make a bold conjecture to conclude: the martial soul absorbs the soul ring produced by the soul beast that is related by blood, and it can promote its own evolution. ”

Xue Ke nodded approvingly: "Brother Ye, what you said makes sense, I am willing to confirm this theory, my first soul ring absorbs the same species of feather light swan, what should I do with the next soul ring?" ”

Xiao Ye adjusted the soul guide: "First of all, we set a small goal, which is to rebel against the ancestor. Now we can clearly see that the soul beast that is related to the Ice Feather Qingluan has a bloodline. ”

The three-dimensional phantom of a big blue bird that looked like a phoenix but not a phoenix appeared in the air, and with this big bird as the center, dozens of bird soul beasts related to it were all around.

"The superior of the Ice Feather Qingluan is the Ice Phoenix, this kind of soul beast only lives in the extreme north, and it is rare for the Ice Phoenix under 10,000 years to appear in people's field of vision, this soul beast can be considered as the fifth soul ring."

"The addition of the first hundred, thousand, and ten thousand year soul rings can make the martial soul produce a certain degree of qualitative change. The soul rings produced by rare soul beasts can even break some of the inherent defects of martial souls, and the subsequent thousand-year soul rings are particularly important. ”

"What you can know is that the original martial soul of the royal family is Ice Feather Qingluan, Ake, your second soul ring, I recommend the Ice Feather Aurora Bird."

"This bird has a very similar bloodline connection with the Ice Feather Qingluan, if my prediction is correct, this soul ring should be able to turn your martial soul into an ice attribute."

Xue Ke nodded: "I listen to you, Brother Ye." ”

After Xiao Ye used his ruby to record some books and materials he wanted to consult, he was about to leave the library, but he didn't expect to meet Xue Qinghe by chance.

"Brother Prince!"

"Too, senior brother."

Xue Qinghe nodded with a smile: "What a coincidence, I met you here, Ake, did you skip class?" ”

Xue Ke stuck out her tongue and hid behind Xiao Ye: "No, we're here to check the information!" Brother Ye can testify to me! ”

Xiao Ye didn't want to tell this fake prince about the theory he was studying, so he directly asked back: "Senior brother came here, but what problems did you encounter?" ”

Xue Qinghe rubbed his forehead a little helplessly: "If you really encounter a little problem, come over and read the notes of your predecessors to see if there is any good solution." ”
