Whether it is the Red Firebird or the Brute Earth Bear, although they are spirit beasts that have mastered spells, they have never thought about why they can master spells.

It's like asking a child why you walk, why do you run.

Therefore, since Yang Yanhan returned to the Blue Wolf Ridge with the Red Fire Bird and the Brute Earth Bear, there would be bursts of terrible birdsong and beast roars from time to time in the Blue Wolf Ridge. After the uninformed people heard about it, they knew it, and they became more and more in awe of the Blue Wolf Ridge.

Every day, Yang Yanhan would draw blood for the brute bear and the red firebird before and after they breathed and breathed. Even though these two spirit beasts had amazing physiques, the continuous months of the situation made the two spirit beasts involuntarily shout as soon as they saw Yang Yanhan.

However, no matter how these two spirit beasts expressed their fears, they could not escape their great fate as Yang Yanhan's test subjects.

Yang Yanhan even often fed some hundred-year-old elixir directly to the two spirit beasts, one was to make up for the shortfall of their continuous blood draws every day, and the other was to observe the direction of their spiritual energy flow after digesting the elixir.

"Big Bear, come over and take medicine!" Yang Yanhan held a hundred-year-old shou wu in his hand and shouted at the brute bear.

However, at this time, the huge brute bear was like a frightened kitten, tightly cowering in the hole, refusing to move half a step.

Seeing that the brute bear that he called the big bear refused to come out obediently, Yang Yanhan immediately shouted: "If you don't come out again, I will dissect you like those blue wolves!"

As soon as I heard Yang Yanhan talk about dissection, I thought of the blue wolves that had become fewer and fewer in the Blue Wolf Ridge recently, and those blue wolves that had been dissected at different times after being forcibly poured with elixir by Yang Yanhan. The battered brute bear hurriedly waved his inflexible limbs and trotted all the way towards Yang Yanhan.

"Good! Come, take your medicine. Yang Yanhan touched the head of the brute bear with a smile, and fed a hundred-year-old red yellow essence to the brute bear.

As a brute earth bear, he can eat a century-old elixir to make a feeling of wind and water cold, and the big bear can be regarded as the first bear in the world.

As soon as the delicious elixir was in his mouth, the bear hurriedly jotted down and chewed it. Soon, the aura that turned into countless essences began to swim around the bear's body.

However, soon, Yang Yanhan took out a small needle that was thin and long. A prick on the bear's body. The blood flowed out like a spring like a fine needle, and was connected by Yang Yanhan in a large bottle.

After receiving more than a few catties of blood in the big bottle, Yang Yanhan pulled out the thin needle, waved his hand at the big bear, and said, "Okay!"

Big Bear heard this. Deng Shi used the fastest speed of the Barbarian Earth Bear Clan, and fled from Yang Yanhan's side with a rolling belt.

With the blood of the brute bear, he left here contentedly and came to a cave in the mountain behind the Blue Wolf Ridge.

Inside this cave is the most huge blue wolf king, and it is even close to the category of demon beasts.

At this time, Yang Yanhan had an evil smile on the corner of his mouth, shook the blood bottle of the brute bear, looked at the blue wolf king, and said to himself: "This time, it should be successful!"

Then Yang Yanhan first stuffed a Hundred Years of Spirit Grass directly into the mouth of the Blue Wolf King, and after it had just digested it, he continued to bleed on the Blue Wolf King's body. On the other hand, he continued to pour the blood of the brute bear into the body of the blue wolf king along countless silver needles.

At the beginning, through the study of the Brute Earth Bear and the Red Firebird, Yang Yanhan thought that the reason why the demon beasts were able to cultivate was because they did not need to operate the aura of heaven and earth according to the exercise route, but absorbed it into the flesh and blood of the whole body.

But when he experimented with an ordinary blue wolf, Yang Yanhan found that this idea was also right and wrong.

The demon beast indeed absorbed the aura of heaven and earth into the flesh and blood of the whole body. Slowly improve yourself. Because of this, its physical strength and lifespan far surpassed that of immortal cultivators, but its advanced speed was also much fuller.

However, not all animals are able to do this. Otherwise, even ordinary people who don't have spiritual roots would be able to cultivate the corresponding exercises. Yang Yanhan didn't believe that no immortal cultivator had been able to create this exercise for so many years.

So, in the end, Yang Yanhan was sure. The key to the demon beast's ability to absorb and utilize the aura of heaven and earth lies in its special bloodline.

As an expert in bloodline, Yang Yanhan soon devoted his limited time to the infinite bloodline transformation cause.

In the past year, there has been at least half of the blue wolf in the Blue Wolf Ridge. If you join Yang Yanhan and stay here for another year, I'm afraid that this Blue Wolf Ridge will be renamed No Wolf Ridge from now on.

And now, after mentioning and concocting a lot of medicinal materials for this blue wolf king, Yang Yanhan began to infuse the blood taken from the brute bear countless times into the body of the blue wolf king. As for the spirit grass that was served for the Blue Wolf King, it was used to save his life.

At the same time, while Yang Yanhan was bleeding and pouring blood for the Blue Wolf King, he kept reciting the tongue-twisting incantations one by one. Combined with the transformation methods of some bloodline wizards, to practice the bloodline transfer method suitable for this world.

"Whew!"

Just when the blood of the brute bear had consumed ten **, the blue wolf king suddenly let out a low and powerful howl.

Feeling the violent earth-based energy that gradually appeared on the other party's body, Yang Yanhan's heart couldn't help but become nervous. After all, among the blue wolves that failed before, none of them were able to survive this step, and all of them were supported by the huge elemental energy and died.

As the wolf king's roar grew louder and louder, his entire body began to grow slowly and imperceptibly.

Under the investigation of Yang Yanhan's spiritual power, the Blue Wolf King's body at this time was already on the verge of collapse.

However, in the next moment, a roar of rage came from the mouth of the Blue Wolf King that pierced for miles around him.

"It worked!" In Yang Yanhan's mind, a trace of ecstasy flashed in an instant. Afterwards, Yang Yanhan looked at the Blue Wolf King, who had become a demon beast and had greatly increased his strength.

instantly swept to the other party's side to restrain the other party, and the spiritual power began to circulate and probe on the other party unscrupulously. Feel the power of the blood veins in the other party's body and slowly enter their body, and finally leave the aura in various parts of the body.

As Yang Yanhan probed the body of the Blue Wolf King at this time, he took out some blood from the Blue Wolf King's body again.

By comparing it with the blood obtained from the Blue Wolf King before, Yang Yanhan found very obviously that the blood of the Blue Wolf King had been greatly changed.

And the successful change of the bloodline of the Blue Wolf King also marked that Yang Yanhan was a big step closer to cultivating these immortal cultivation techniques. (To be continued.) )
