Even if it is a spirit root rune made from the bloodline origin of a demon beast of the same level, as long as the spirit root grade is one level or more higher, it will be useful. However, if the bloodline origin grade infused with the spirit root rune is low, it will be useless to use it for a high-grade spirit beast. On the other hand, there is no problem, this spirit root rune can still allow spirit beasts of the same grade to improve their first-grade talent.

This method of use is the best way for Liu Bo to use it, and it will not cause any waste.

In other words, if Liu Bo used the Spiritual Lake Stage Bloodline Origin of the Fire Five-Rank Spiritual Root to make the Spirit Root Divine Rune, the best object to use it would be the Spirit Beast of the Spiritual Lake Stage Fire Four-Rank Spiritual Root. After the Spirit Lake Stage Spirit Beast of the Fire Four-Rank Spirit Root uses this talisman seal, the Fire Spiritual Root talent can be smoothly upgraded to the Fifth Grade.

Liu Bo also has a condition for choosing to inject the bloodline origin of the rune, that is, he can only choose the bloodline origin injection of the single spirit root, otherwise the rune seal cannot be successfully made.

Although the Spirit Root Rune can only allow the Spirit Beast to improve the first-grade Spirit Root talent, it does not limit the types. For example, a spirit beast that was originally a single fire spirit root, after using a variety of rune seals, it could add the remaining eight spirit roots, but the talents of the rest of the spirit roots were all one product.

The spiritual root rune can improve all the spiritual root talents of the monk, although the highest is only one grade, but this effect is definitely very anti-heaven when combined. Liu Bo himself was deeply shocked.

After coming to these conclusions, Liu Bo began to think again, if the spirit beast in the Qi cultivation period used the Spirit Root Rune to increase the spirit root grade, after advancing to the Spirit Condensation Period, could it still use the Spirit Root Rune to increase the Spirit Root talent?

Since there is this speculation, it must be verified before a definite conclusion can be drawn.

Liu Bo found a spirit beast at the peak of the Qi cultivation period to verify this guess. For this wood-based fourth-grade spirit beast, after using the wood-based fifth-grade spirit root rune during the Qi training period, this spirit beast's wood-based spirit root talent was increased to a fifth-grade.

Feeding this spirit beast a spirit pill that increased cultivation, it only took half a day for this spirit beast to advance to the concentrating stage.

Liu Bo used a Wood Six-Rank Spirit Root Rune for this spirit beast again, and the Wood Six-Rank Spirit Root Talent of this spirit beast was once again raised to the Sixth Grade, and nothing happened in the middle.

After this experiment, Liu's speculation was basically proven to be feasible.

But to fully prove his guess, further experiments will be needed to determine further.

Liu Bo continued to feed this spirit beast a large amount of spirit pills, and a month later, this spirit beast advanced to the Spirit Lake stage.

Now that this spirit beast is already a sixth-grade wood-based talent, Liu Bo once again used a wood-based seventh-grade spiritual root rune from the Linghu stage for him, and the wood-based spiritual root talent of this spirit beast has been successfully improved to seventh-grade again.

At this point, the experiment can only be ended for the time being, because it will take too long to raise this spirit beast to the supernatural stage. Further experiments can only be verified slowly in the future.

The combination of the bloodline origin and this mysterious rune has produced such a god-defying rune, even after so many days, Liu Bo is still agitated and difficult to calm down.

The Spirit Root Rune is too precious, and in addition to having no effect on monks with super talents, it has an effect on monks below those with super talents. As long as you have the right spiritual root rune, even if an ordinary person doesn't fall halfway, there is hope that after becoming an immortal, he will become a monk with super talent. Of course, this is only a theoretical matter, even if an ordinary person uses the Spirit Root Rune, because the talent in the early stage is too low, it is impossible to achieve much at all, unless there is a large supply of cultivation resources, there is a slight possibility of becoming an immortal.

After having the Spirit Root Rune, as long as the talent is not too bad, it is not too difficult to cultivate a monk with super talent, if Liu Bo is willing, he can completely rely on this anti-heaven advantage to cultivate his own powerful force.

Whether it is in the Liu Mansion or in the Shenxiao Sect, Liu Bo's current status is very high, and there is no need to cultivate forces at all. This kind of anti-heaven rune, he will only use it on his relatives and friends, and it is impossible to spread it to the outside world.

Give it to relatives and friends to use, this is a matter for the future, Liu Bo now wants to use the spirit root rune on his body.

After his observation, the spirit beast used the Spirit Root Rune to increase its talent, although it would also suffer a lot, but it was far lower than the pain he suffered by absorbing the bloodline origin. If Liu Bo injected the bloodline origin into the Spirit Root Rune, and he used the Spirit Root Rune to increase his own talent, would he suffer less pain?

Thinking of this, Liu Bo immediately began to verify.

Liu Bo has accumulated a lot of bloodline origins of spirit immortals and even earth immortals now, but because the pain he endured when absorbing the bloodline origin is too great, it limits the speed of his absorption, so there are still many bloodline origins of the remaining spirit immortals and earth immortals, which can fully support him to carry out experiments.

He used half a month to make all the bloodline origins of the fire single spirit root spirit immortals and earth immortals into spirit root runes.

He first picked up a spirit immortal-level fire super grade spirit root rune and used it on his body.

A mysterious blood-colored rune entered his sea of consciousness, and the mysterious power in the rune began to penetrate his bloodline and spiritual root. Along with this process, bursts of pain swept through his body, including his soul. Although the pain he is suffering now is severe, Liu Bo has a smile on his face. It turned out that Liu Bo's guess was indeed correct, the pain he endured with the Spirit Root Rune was much smaller than the pain he endured by directly absorbing the bloodline origin, and the efficiency of using the Spirit Root Rune to improve his talent was also much higher than directly absorbing the bloodline source. In the long run, Liu Bo will save a lot of time.

A quarter of an hour later, the mysterious power of this talisman had been fully absorbed by Liu Bo. If he directly absorbed the bloodline origin in this talisman seal, it would take nearly an hour to absorb it all. In this way, using the Spirit Root Rune could save him about seven or eight times the time compared to directly absorbing the bloodline origin. And the pain he endured was reduced by at least half, which was definitely a huge piece of good news for Liu Bo.

It has been a long time since Liu Bo's ninth-line spiritual root talent reached the super-grade level, and he has been absorbing the bloodline origin of the fire system for a period of time, but until now, he has not seen any further changes. He was now a little skeptical, was there no point in doing this, and could he use this method to make his talent reach the level of a spirit body?

Now that he had the Spirit Root Rune, he could save a lot of time, and the pain he endured was greatly reduced, and he was full of confidence in reaching the Spirit Talent again.

From this day on, in addition to using the Tongming incense burner every day to comprehend the law, Liu Bo will also find time to use the spiritual root rune to improve his fire talent. He always believed that when quantitative change reaches a certain level, it will inevitably lead to qualitative change.

He clearly felt that the mysterious power in the Spirit Root Rune had indeed been integrated into his body, Spirit Root, and Divine Soul, and it had not caused the slightest waste. If this situation continued, he believed that one day his Fire Spirit Root talent would break through the existing shackles and eventually reach the level of a Fire Spirit Body.

Because there was no hope of breaking through the fire spirit body for the time being, Liu Bo was still mainly focusing on cultivation, and most of the time he spent every day contemplating the law and condensing mana. Because the Liu Mansion has a complete fire system secret realm, Liu Bo temporarily focuses on understanding the laws of the fire system.

He has been staying in the secret realm of the fire system in the underground palace for a long time, and his comprehension of the laws of the fire system is advancing rapidly, and he is entering the realm very quickly.

With this kind of compact cultivation method, Liu Bo did not feel the slightest burden, because his time allocation was reasonable, but he felt that every day was very easy.

After continuing this cultivation method, after about a month, Liu Bo took longer and longer to absorb the Spirit Root Rune. He was now absorbing a super-grade Immortal Rune, which had been extended from about a quarter of an hour to about an hour. Moreover, when absorbing the spiritual root rune, the pain of the body and soul became more and more severe.

When this happened, Liu Bo not only did not have the slightest worry, but his heart was full of expectations.

He believes that as long as he persists for a longer period of time, the quantitative change has reached the limit, and it is the time for the qualitative change to come. His fire spirit root talent, from a super grade to a fire spirit body, should not take a few days.

Liu Bo persisted for another seven days, and today he used a super-grade fire spirit root rune, after using this rune, the absorption of the mysterious power was extremely difficult, and he had now insisted on it for two hours, and the mysterious power of the rune, he still hadn't absorbed it all.

And this time the pain he endured was extraordinarily huge, whether it was ** or soul, the degree of pain had increased more than ten times compared to before. If it weren't for Liu Bo's incomparably resolute willpower, I'm afraid he would have been unable to hold on to it.

Another hour passed, and Liu Bo's pain suddenly increased greatly, and with the perseverance of his willpower and the strength of his divine soul, he almost passed out. This tremendous pain lasted for a quarter of an hour, and just when Liu Bo saw that he couldn't hold on, all the pain suddenly dissipated, and an indescribable feeling of comfort permeated his whole body, and even his soul seemed to be soaked in a fairy spring, indescribably comfortable and comfortable.

Liu Bo was immersed in this incomparably comfortable feeling, and it was not until half an hour later that this feeling completely subsided.

Liu Bo opened his eyes and muttered to himself: "Talent has finally made a breakthrough again, and now I am really a fire spirit body, I didn't expect the feeling of breakthrough to be so comfortable." With this half hour of enjoyment, all the suffering that I had endured before was worth it. ”

After such a long period of hard work, Liu Bo endured the pain of soul transformation every day, and today he finally came to the end, and he had a great sense of satisfaction and accomplishment in his heart.

Now that his fire talent has reached the fire spirit body, then all other talents will one day also advance to the spirit body. His breakthrough today is of great significance. (To be continued.) )
