Demon beasts don't have any spiritual roots, so although they have experimented with the method of changing their bloodlines, they still need a lot of experimental materials if they want to experiment again to replace the spiritual roots with bloodlines, or even artificially create spiritual roots.

Ever since he returned to the Seven Xuanmen, Yang Yanhan had occasionally appeared to point out Han Li and Zhang Tie, and then to treat some of the high-level people of the Seven Xuanmen. It was as if he had disappeared, and he hid in the medicine shed in the deepest part of the Valley of the Divine Hand all day long, not knowing what he was doing.

And Han Li, who had always been slack, had tried to use his "useless" Changchun Sutra to unleash this indestructible little fireball after Yang Yanhan had quietly taught him a fire bomb technique. For the cultivation of the Changchun Sutra, the interest has really increased.

In addition, Yang Yanhan gave Han Li some "Golden Marrow Liquid" from time to time to take it, and his cultivation of the Changchun Sutra was naturally a thousand miles away.

However, since the year of Cangwolf Ridge, Yang Yanhan has also learned the method of discerning the spiritual roots of this world. Although he doesn't have the mana of this world, with Yang Yanhan's amazing spiritual power, he can barely do it.

After Yang Yanhan's test, Han Linai was a Four Spirit Root Cultivator.

Generally speaking, the "spiritual root" is divided into five elements such as metal, wood, water, fire, earth, etc., and most people's spiritual roots are mixed with these five or four multiple attributes, although these people can also sense the aura of heaven and earth, but the effect of cultivation can be said to be miserable, basically can only practice the five elements of the basic exercises in the stage of refining qi, practice to the third or fourth layer, and then move forward an inch, and generally have no hope of crossing the foundation building period in their lives.

Therefore, spiritual roots with five or even four attributes are also called "pseudo-spiritual roots" in the immortal cultivation world, to show that they are different from "true spiritual roots" that only have two or three attributes and can be cultivated relatively quickly.

As for the single spiritual root with only one attribute, it is called "Heavenly Root" by the Immortal Cultivation Realm, which means the darling of the heavens. Because a person with this kind of spiritual root, no matter what attribute he is, his cultivation speed is two to three times that of an ordinary spiritual root person. Moreover, when you cultivate to the peak of the foundation building period, you don't need to face the bottlenecks that you should face when you enter the foundation stage, and you can easily start to form a pill.

Obviously, Han Li, the son of fate, was a "pseudo-spirit root" monk who lacked a golden spirit root. If he didn't have this mysterious vial, I'm afraid he wouldn't even have the luxury of building a foundation in his life.

And Zhang Tie, another disciple that Yang Yanhan easily accepted, was actually under an unintentional test by Yang Yanhan. It was found that it was actually the "true spirit root" qualification of the three spirit roots. It's just that among his three spiritual roots, there happens to be no wood spirit roots, so he can't cultivate the Changchun Sutra.

It's just that Yang Yanhan found that Zhang Tie not only has this one-in-ten thousand spiritual root qualification. And it was much better than Han Li's qualifications. However, Yang Yanhan was not prepared to teach his immortal cultivation techniques, and moreover, he specifically told Han Li not to tell the other party everything about the immortal cultivators.

Since Qixuanmen came to Caixia Mountain, it has been in business for a hundred years, controlling more than a dozen small towns, and has three or four thousand disciples, and is one of the two veritable overlords in the local area. The only other force in the local area that can compete with the Seven Xuanmen is the "Wild Wolf Gang".

The predecessor of the Wild Wolf Gang was a group of horse thieves who burned and killed and plundered in the border of Jingzhou, and later they were surrounded and suppressed by the government several times. Some of them accepted the government's recruitment, and the other part of the horse thieves became the Wild Wolf Gang, but the fierceness of the horse thieves who were fierce and bloodthirsty, and dared to kill and fight was passed down together, so the Seven Xuanmen was repeatedly at a disadvantage when they clashed with the Wild Wolf Gang. Although there are many towns and villages controlled by the Wild Wolf Gang, they will not be able to operate, and the degree of wealth is far less than that of the towns under the Seven Xuanmen.

The Wild Wolf Gang is very covetous of several wealthier territories under the Seven Xuanmen, and has often provoked conflicts between the two recently, which has caused a headache for the current Qixuanmen master, which has also become the main reason why the Qixuanmen has repeatedly expanded the number of disciples in the sect in recent years.

And the conflict between the Seven Xuanmen and the Wild Wolf Gang gave Yang Yanhan a good excuse. He suggested to the king of the Seven Xuanmen. Use the captured Wolf Gang's gang to test the medicine.

At the beginning, this suggestion met with opposition from many high-level leaders of the Seven Xuanmen, and even believed that this "Doctor Mo" was a spy sent by the Wild Wolf Gang.

Merely. Soon, in a fire with the Wild Wolf Gang, Yang Yanhan rejuvenated himself and rescued the seriously injured and dying Deputy Hall Master of the Blood Blade Hall, and all the voices of opposition quickly disappeared.

In this way, as the conflict between the Seven Xuanmen and the Wild Wolf Gang became more and more intense, a steady stream of Wild Wolf Gang members were sent to the Valley of the Divine Hand.

Although the people of the Seven Xuanmen didn't know what these prisoners of the Wild Wolf Gang were used for. However, none of the Wolf Gang sent into the Valley of the Divine Hand came out of the Valley of the Divine Hand.

And only Han Li and Zhang Tie knew that after those people were brought into Yang Yanhan's medicine garden, not long after, there would be bursts of terrifying screams.

And these days, the brute bear, the big bear, and the red firebird, the big bird, are becoming more and more detrimental. Although the various hundred-year-old elixirs they have eaten are enough to make themselves advance to the foundation building period several times.

However, the blood released from the two of them was enough to fill a pool of water.

It has been more than a year since Yang Yanhan came back, and on this day, Yang Yanhan rarely did not continue the experiment, but just stayed quietly in the hut of his medicine garden.

At this time, when the sun was shining, the warm sunlight poured in from the open skylight and shone on Yang Yanhan's body, making him comfortable and narrowing his eyes into a thin slit comfortably, coupled with the whole person lying in an oblique position, Yang Yanhan's whole person looked unusually lazy.

The spiritual root problem, as a problem that has plagued the entire immortal cultivation world for tens of thousands of years, could not be solved so easily by Yang Yanhan. Those members of the Wild Wolf Gang, after being poured into the highly condensed spirit beast blood by Yang Yanhan, not only did they not condense something similar to the spirit root in their bodies as Yang Yanhan expected.

On the contrary, as soon as this blood condensed in their bodies, they would instantly riot, bursting with amazing power and blasting their entire bodies apart.

And recently, for some reason, there have been a lot fewer conflicts between the Wild Wolf Gang and the Seven Xuanmen. At this moment, the experimental materials sent to the Valley of the Divine Hand were greatly reduced.

And now, after casually throwing the body of the last unlucky guy to the big bear, Yang Yanhan had to take a break for a while, and by the way, think about whether there was a problem with his previous method.

After all, as time passed, Yang Yanhan already felt that the will of the world was becoming more and more oppressive to him. It seems that he is very soon, and he must make a trade-off between this mysterious vial and this world, otherwise, the will of the world will never let go of himself easily. (To be continued.) )
