"Jiuyang Burning Sky Fist" is the most yang and rigid boxing method, and it has a strong restraint power against yin and evil things, plus whether it is Zhao Yi's earth-centered flame or Xuanhuang flame, it is the supreme yang flame between heaven and earth, and it is the most restraining this kind of resentful soul, so with the cooperation of the two, only a few punches, this resentful soul was killed by Zhao Yi!

"Bell!"

The moment the resentful soul was killed, a dark gray crystal the size of an adult's fist fell from the sky and fell to the ground, exuding a faint aura of resentment.

"I didn't expect this resentful soul to reach the level of being able to produce resentful spirit stones. Raising his hand, a suction burst out to absorb the dark gray crystals on the ground into his hand, and he couldn't help but be amazed when he found it.

The resentful spirit stone is generally a kind of treasure above the sixth order that will only appear after the resentful soul is killed, that is to say, at the very least, it must also have a Tianzun-level resentful soul, and it can only produce the resentful spirit stone after being killed.

Because the resentful soul is the obsession and remnant soul of the warrior after death, the resentful spirit stone contains the most powerful will comparable to that of the strong man in his lifetime, and if the soul power invades it, he can use his own will to fight against it, which can play an excellent role in the tempering of the will.

The stronger the martial artist's willpower, the higher the soul power, and the farther the realm he can break through, so this resentful spirit stone can be regarded as an extremely precious treasure in the cultivation world, even more valuable than the evil crystals produced after being killed by the blood demon of the same level.

The fingers were slightly forced, and the resentful spirit stone in his hand was easily crushed, and a powerful and condensed will impact instantly disappeared into Zhao Yi's mind, and Zhao Yi also mobilized his soul power to oppose it with his own will.

In this kind of confrontation, Zhao Yi clearly felt that the strength of his soul power had increased very slightly, although it was not too obvious, but it was really improving.

Martial arts cultivation, in fact, it is relatively easy to improve cultivation, because there are too many heavenly and earthly treasures and pills that can improve cultivation in this world, although the strength raised by taking heavenly materials and earthly treasures will be somewhat vain, and the foundation is unstable, and it will affect the future development, but after all, the cultivation will be improved.

Although these methods will have a big price, for some big forces, this price is nothing at all.

But even so, it is not so easy to improve one's cultivation, because there is one extremely important factor that restricts the improvement of a martial artist's cultivation, and that is the realm of soul power.

If a martial artist wants to improve his cultivation, he must have the corresponding soul power realm before that, and only when the soul power realm is reached, the bottleneck before the breakthrough will be broken, so that the cultivation can break through the shackles and go to the next level.

It's just that for martial artists, there are far fewer ways to improve the realm of soul power than methods to improve cultivation, and basically they can only rely on the martial artists themselves to comprehend the avenue between heaven and earth, through the comprehension of martial arts, and through the perception of life and death to improve the realm of soul power.

Some strong people with high talents, the faster their soul power realm improves, their cultivation will naturally improve faster, and naturally the word genius is born.

However, everything has an organic fate, and there are still some treasures in heaven and earth that can improve the realm of soul power, such as the evil crystal produced after the blood demon is destroyed, and the resentful spirit stone in front of you, and some more precious demon demon stones...... Fast-eyed reading

Although the elixirs refined by those alchemists to improve their cultivation can also improve the realm of the martial artist's soul power, it is just that after the level of improvement, it will have a great impact on the improvement of the martial artist's soul power in the future, and the higher the grade of the elixir, the greater the impact on the future, and some will even make it impossible for the martial artist to continue to improve in the future.

Of course, even so, some strong people whose potential had been exhausted were still willing to take such elixirs to improve their cultivation, because if they didn't take it, it would be difficult for them to reach this realm even in their lifetime.

However, for true geniuses, they would not take pills or anything like that to improve their cultivation, because they could reach that realm with their own talents.

Soon, the power in the resentful spirit stone was all consumed, and Zhao Yi could clearly perceive that his soul power had improved to a certain extent.

Although Zhao Yi is the reincarnation of the Sword Master, and he has awakened the memories of his previous life, the soul realm still needs to start all over again and cultivate again.

But even so, as an alchemist, Zhao Yi's soul power realm is much stronger than that of a strong person of the same level, and he has the memory of his previous life, after all, he is more advantageous than other strong people, at least for the time being, Zhao Yi's soul power realm should be infinitely close to a strong person at the level of the Great Emperor.

"Although this resentful spirit stone has improved my soul power realm, the improvement is still not very large, and this level of resentful spirit stone is unlikely to have any effect on me, if you want to greatly improve the soul power realm, I am afraid that you will need a more powerful resentful spirit stone produced by the resentful spirit. After feeling the extent of his improvement, Zhao Yi said secretly in his heart.

Generally speaking, low-level treasures basically have no effect on high-level cultivation realms, at most, when they are used for the first time, they can have a slight effect, just like this resentful spirit stone that has been crushed by Zhao Yi.

"It's a pity that it's just a Celestial-level resentful soul, and it's not that particularly powerful Celestial, it doesn't seem like there should be an emperor core. ”

After killing the resentful spirit, Zhao Yi searched in the valley, but found nothing else except the corpses of two or three warriors.

Moreover, the corpses of those two or three martial artists also looked like they had been dead for a long time, but I am afraid that they were the Heavenly Venerable Realm powerhouses who had entered the Emperor's Death Abyss in the previous Battle of Ten Thousand Venerables.

"It seems that we have to continue to work hard!" Zhao Yi shook his head, left the valley, and continued to rush through the Emperor's Death Abyss.

If you want to obtain the emperor core, there is definitely no place where the Tianzun-level powerhouse falls, and only the place where the emperor-level powerhouse falls, will the emperor core be generated.

However, the resentful soul formed after the fall of the emperor-level powerhouse must have all the memories of his life, and he can use his martial arts before his death, even if his combat power is far less than when he was in his heyday, but it is not something that ordinary Tianzun can deal with.

As Zhao Yi gradually deepened, he also vaguely felt some fluctuations in the battle, after all, there were as many as 10,000 people who entered the Emperor's Death Abyss, and Zhao Yi had been running here for several days before he met someone else for the first time, which was already relatively rare.
