Yuan Jie remembered the dragon slaying sword brought out of the purple dragon cave again, and now he was hiding in his dantian, and at the moment his mind moved, the dragon slaying sword turned into a black light and appeared in his hand, feeling the coldness of the sword handle, and the black light of the sword was constricted in the dimness, and it didn't look very conspicuous.

Internal power ability, there are special martial arts, when using weapons, you can need to infuse internal force into the weapon, so as to exert great power.

It seems that he should also practice his sword skills, so that he can use his internal strength ability as a killer weapon, and he may be able to save his life in a critical moment.

Yuan Jie is also a little distressed, after all, there are too many abilities, and he will be distracted when he practices, he understands the truth that Bo is not refined, and his energy mainly has to be focused on the fire ability, after all, this is the ability he first awakened, and it is also the ability he is most familiar with. Of course, the ability of internal strength must also be paid attention to, and the combination of melee attack and ranged attack is something that Yuan Jie has already decided.

As for the shear and worm abilities, put them aside for now.

.......

In the next few days, Yuan Jie spent all the time in the library, he looked for all the information on the arrangement of characteristics, not only the fire system, but also other ability systems, through a large number of information to understand, he found that many of the energy characteristics are common to each ability series, only a few are unique.

The energy tide that sent him out of the Purple Dragon Cave contained the rules of operation, and he gradually had eyebrows, of course, he only had eyebrows, if he wanted to understand it thoroughly, there was still a distance of 109,000 miles, and the fusion of the characteristics arrangement was too complicated, thousands of times more complicated than superposition, even if Yuan Jie knew the trajectory of the energy tide very well, he still only saw the appearance, but he didn't know much about the meaning of the connotation.

The spatial collapse caused by the energy tide, with Yuan Jie's current ability, he judged the five fusion characteristics, even if it was just the superposition of the characteristics, the five characteristics were already a fifth-level ability technique, not to mention the fusion, it would be even more complicated.

Because Yuan Jie has the induction memory of the operation rules of energy tides, in countless experiments, his understanding of the operation rules of energy tides has become more and more profound.

Now Yuan Jie has an idea, that is, to apply this operating rule to the battle, the power will be very terrifying, especially at the critical moment when the life and death battle is approaching, this operating rule is becoming more and more important, even if it is not a complete operating rule, it is definitely not something that the other party can resist.

Time passed day by day, and the battle of life and death was getting closer and closer, Yuan Jie was immersed in cultivation or studying the operating rules contained in the energy tide every day, and even Yuan Xifeng saw Yuan Jie less often, obviously, she didn't want Yuan Jie to be distracted.

In the cultivation room of the Purple Clothes Mansion.

His eyes were so closed that Yuan Jie suddenly opened his eyes, and a trace of joy flashed on his face.

With a flick of his hand, a sea of hellfire appeared in front of him, gray flames rising a foot high.

It's not an anomaly, it's just a massive confluence of hellfire.

The transpiring hellfire suddenly formed a circle of fire waves, which spread towards the center, and then disappeared in the center, but Yuan Jie clearly saw that the most central point appeared very unclear and appeared a depression, and as more and more fire waves were transmitted to the center point, the depression was gradually expanding.

However, this phenomenon is not obvious, Yuan Jie's eyes are staring, and he doesn't blink his eyes.

I don't know how long it took, the waves of fire kept spreading towards the center, and the depression in the center was finally the size of a sea bowl, and this depression was not directly concave, but had a slope, making this depression not too obvious.

Yuan Jie's face became more and more serious, his eyes sparkled, and he muttered: "The most critical step is to integrate the coiling and suction characteristics." ”

As soon as his voice fell, the sea of fire suddenly changed, and the waves of fire rotated even more rapidly in the transmission, causing the originally gentle circles of fire waves to become more and more ferocious, and in the blink of an eye, the entire sea of fire rotated, forming a larger and larger whirlpool.

"No, why can't it be fused, it can only be stacked?"

Yuan Jie's brows furrowed, staring at the hellfire vortex, but at this moment, his mind was recalling the trajectory of the energy tide.

"Isn't that what I thought? Fusion ~~~ superposition, what is the mystery? ”

Little Ant once said that the difference between fusion and superposition should be understood literally, but is this really the case?

Yuan Jie is at a loss, maybe he should think from a different angle, he was a college student in his previous life, and he can think from physical phenomena, chemical phenomena, biological phenomena, etc., hey! Yuan Jie's mind suddenly flashed, as if he had captured some clue that was fleeting.

Physical phenomena, chemical phenomena ~~~ Yes, it is a chemical phenomenon, the fusion of two different substances, maybe they may mix, maybe they will produce chemical changes, so as to become a new substance, does it mean that the so-called fusion of characteristics is actually the fusion of two properties to produce a new characteristic, not just the fusion of matter and matter?

As soon as his thoughts opened, Yuan Jie suddenly had a feeling of enlightenment.

The coiling and pulsating characteristics can form a new characteristic through the medium of energy, and once the number of this fused characteristic reaches a certain point, it will become the so-called energy operation rule.

Thinking of this, Yuan Jie immediately focused all his attention on the flame vortex he was looking at, he would further produce a fusion of the two characteristics such as chemical change, this fusion is not so easy, like chemical change, a certain condition needs to be met.

And the fusion of the two characteristics, the conditions required need to be tested by Yuan Jie.

Experiments again and again, failure again and again, but Yuan Jie was not discouraged, the direction of his experiment was mainly on the standard type of the two characteristics, since these characteristics are decomposed by the operating rules, then the standard feature arrangement has become the key to reintegration.

Although Yuan Jie's comprehension of the arrangement of characteristics is very high, it is not so easy to achieve the most standard arrangement, and the slightest difference will make the conditions for fusion not meet the standard.

I don't know how long it took, the originally violently boiling flame vortex calmed down a lot, whether it was the transmission of the fire wave or the swirling hellfire sucking, it became calmer, not the previous fierceness, but all this did not stop, but expanded the power in silence.

Yuan Jie finally showed a smile on his face, he knew that the fusion of the two characteristics had finally begun, and with a beginning, then it would be easy to do next.

When the two characteristics were completely fused, Yuan Jie's spiritual power only sensed the existence of a new characteristic, but this characteristic played the role of pulsating and absorbing the two characteristics, and Yuan Jie found that the effect of this newly fused characteristic was more than ten times stronger than the superposition of the previous two effects.

Yuan Jie was stunned, is this the power after the fusion of characteristics?

Is it true that the more characteristics of the fusion, the greater the effect?

What if you could harness the power of rules? The huge waves in Yuan Jie's heart turned upside down, and he could no longer calm down, no wonder from the grandmaster to the saint, they were two completely different levels, the transformation from human to god, and the gap was much greater than that of any previous two levels.

Mastering the fusion of characteristics, and even mastering the rules, how can it not be powerful, even with the same ability strength, the difference in strength can be calculated by a hundred and ten times!

Yuan Jie's heart was full of anger, he finally found the biggest weapon for leapfrogging challenges, otherwise no matter how high his ability potential is, no matter how strong his combat consciousness is, the faster his ability comprehension is, he will not be able to challenge the big realm gap, at most it will be the challenge of the small realm gap.

With the fusion of this characteristic, I have a certain grasp of the life and death battle that is about to begin.

I was able to successfully fuse the characteristics, in addition to finding the mystery of the fusion, I am afraid it is also related to the condensation of my soul, otherwise the fusion of the characteristics will not be a patent above the saint level!
