Of course, Qin Ying's "constant" state of mind is now one level higher than empty. My heart is eternal, let you go big waves, let you wind and frost, rain and snow, and never change my original intention. This is "constancy".

Maybe there is a higher state of mind on top of the state of mind of "Heng", but at this moment, Qin Ying has no heart to put it on it.

"The power of the soul origin gives me the possibility of invincibility, but it also gives me the possibility of falling. It seems that this soul origin power cannot be abused. At least not what I can use with impunity right now. At this moment, Qin Ying knew very well in his heart, he knew what he wanted. "This soul origin power is a double-edged sword, if used well, it can help me reach the peak, and if it is not used well, it will also hinder my cultivation path. Then from now on, unless you encounter a moment of life and death, you will never fight with the power of the soul origin. ”

Qin Ying always believed that fighting is the way to be strong. This is not to be taken shortly.

"However, the power of the soul origin is more than just killing. "Qin Ying has a lot of comprehensions about the soul origin, and using the power of the soul origin to kill people is just one of the insignificant ones.

Mastering the Soul Source is equivalent to controlling the Soul!

Today's Qin Ying can easily cast the illusion, and there is no need to release the soul realm at all. He can also easily enslave enemies, no longer needing the aid of illusions, no matter how powerful they are.

But that's just one aspect. Mastering the soul origin, Qin Ying can regulate the soul of living beings.

The soul is real, it has intensity, it has density. And Qin Ying can adjust these characteristics of the soul by adjusting the percentage of the soul origin in the soul.

In other words, if a person who was born stupid and had an incomplete soul, Qin Ying could easily cure him through the power of the soul origin. Even Qin Ying could turn an ordinary cultivator into a cultivation genius. And this only needs to adjust the concentration of the soul origin in his soul.

The greater the concentration of the soul origin in the soul, the greater the percentage, the closer the soul is, and the greater the strength of the soul. And the stronger the soul, the easier it is to communicate with the origin in the universe, and it is easy to perceive the origin law.

This is where the power of the soul origin is most powerful. Because it can easily create one genius after another.

This discovery made Qin Ying a little excited. You must know that the cultivation talent of the Mengbei clan is low. If Qin Ying could change the cultivation talent of the Mengbei clan through this method, then in the future, the Mengbei clan would definitely become a race comparable to the Barbarian clan and become a powerhouse in the universe.

"That's a good idea. However, these are only theories, and have not yet been put into practice. Looks like I'm going to have to experiment with it myself. Qin Ying nodded with satisfaction.

Subsequently, Qin Ying ordered Airy and Marbury to catch some animals and demon beasts.

At this moment, there was a small cage in front of Qin Ying, and there was a fiery red rodent animal in it. This is an animal called the Red Rat. Loved staying near the volcano.

Qin Ying looked at this lovely red ying mouse with a smile, and as soon as his thoughts moved, a source power entered the soul of the red ying mouse. However, the next moment, there was no more movement in the eyes of the red mouse, and it turned out that he was dead.

"How is this possible? I just injected it with the soul origin, and did not extract the soul origin, why would it die?" Qin Ying was full of puzzlement.

"I don't believe it anymore. Qin Ying turned to the cage of a bird of paradise and once again injected the bird of paradise with a soul origin.

However, like the red rat, the bird of paradise, which was still flying in the cage with agility, suddenly fell to the bottom of the cage and was no longer alive.

Next, lizards, tanuki, hyenas, and other animals died at Qin Ying's hands one after another.

Qin Ying was really worried at the moment, "Why is this happening? I'm just injecting the soul source! Are these methods really not working? It's just talking on paper? If that's the case, I'll be happy in vain." ”

At this moment, almost all the animals captured by Qin Ying's order Airy and Marbury had died, and only one Black Hades Tiger remained.

Qin Ying looked at the three-meter-long Black Hades Tiger in front of him, and was a little hesitant in his heart. He doesn't know if he can succeed this time, and if he doesn't succeed this time, he will give up.

The Black Dark Tiger roared at Qin Ying, as if sensing Qin Ying's threat. It curled up in a corner of its cage, guarded cautiously.

Qin Ying ignored the Black Stygian Tiger's expression, he once again transported a stream of soul origin power and injected it into the Black Stygian Tiger's soul.

"We must succeed, we must succeed!" Qin Ying secretly prayed in his heart.

Finally, this soul origin power was all injected into the soul of the Black Stygian Tiger. And this time, it seemed that Qin Ying's prayer had an effect, and the Black Hades Tiger did not fall down on this. It's more dynamic than ever.

"It worked, I really succeeded. Qin Ying was ecstatic at the moment. He knew that his ability to change the soul through the power of the soul origin was not just a theory, it was practical.

"However, why did so many experiments fail just now?" Qin Ying was puzzled.

"I don't know what will happen if you inject another soul origin into the Black Stygian Tiger, will it be more agile?" Qin Ying Ghost sent another soul origin power into the soul of the Black Stygian Tiger.

However, this time, as soon as the soul origin was injected into the soul of the Black Stygian Tiger, the Black Stygian Tiger was killed. Qin Ying could easily feel that the Black Dark Tiger's soul had completely dissipated.

"How could this be, Qin Ying was shocked. He didn't expect this to be the result at all.

Qin Ying sat down and began to analyze the gains and losses of the experiment, "I obviously succeeded the first time just now, why did I fail the second time? And what does that second defeat mean?"

Qin Ying looked at the room full of various animals, large and small, and thought in a flash of inspiration, "Could it be that I have injected too much soul origin power?"

Among the animals in Qin Ying's room, the Black Hades Tiger was the largest animal. No other animal is as big as the Black Plutox. In the animal kingdom, the size of the soul of animals that have not been cultivated is related to their body size. The larger the animal, the larger its soul. Otherwise, the soul will be smaller. This was also discovered by Qin Ying by observing the souls of these animals.

Generally speaking, yes, but of course there are some special ones. For example, the parrot, although it is not large, it is very psychic, and its soul is larger than that of some cats and dogs.

However, for these animals with different soul sizes, the soul origin power that Qin Ying injected every time was exactly the same. It never occurred to him to inject different amounts of soul origin into the size of an animal's soul.

"Maybe the more soul origins in the soul is not the better, it seems that I have to try again. I'm going to make it this time. Qin Ying was extremely confident at the moment. He has found the root of the problem.
