"It's so depressing." Ye Qingcheng's face hurt, he just never dreamed that improving his strength would be able to cause trouble for himself. Now, due to the impact runes attached to the Book of Fire Demons, after Ye Qingcheng's magic hits, it will push the monster away, affecting the release of his continuous combo attacks.

Ye Qingcheng's situation is that his own technology is typical of his own strength growth, and there are two ways to solve it, one is to take the initiative to give up the existing Fire Demon Book and restore the flame bomb to its original state. Another is to update the existing technology and allow yourself to grow.

It is obviously not advisable to abandon the Book of Fire Demons, and Ye Qingcheng is obviously very concerned about the strength of the Book of Fire Demons, so the only way he can do it is to improve his skills.

It's a pity that the improvement of skills is not overnight, it takes years of practice and accumulation, fortunately, Ye Qingcheng has a good foundation, although there is not much special practice, but this guy is either fighting or fighting monsters until late, and he has accumulated a lot of experience.

After killing a wave of flame demons here, Ye Qingcheng had already roughly figured out the direction that should be explored.

Since a fire charge with an impact rune will push the monster backwards when it explodes in front, wouldn't the monster stop moving if the front and back sides of the monster exploded at the same time?

Just thinking of it, Ye Qingcheng aimed at an unlucky flame demon, and raised his hand to blast out a series of flame bombs, in order to test his new tactics, but also to practice his skills by the way, so Ye Qingcheng used a newly practiced third-level flame bomb this time.

Fire Charge! Fire Charge! Fire Charge! Fire Charge!

Since there was no spell chain, Ye Qingcheng's flame ball could only rely on active chanting, and its speed was naturally much slower than that of the sixth-level flame charge. But fortunately, this time Ye Qingcheng's experiment was only a spell combo, not a continuous combo, and the requirements for the casting speed were not too high.

Thundered!

-567！

Spell Combo!

Under Ye Qingcheng's control, the two flame bombs directly hit the flame demon's face door head-on, and the huge impact directly hit it back a few steps, just hitting the two flame bombs that were galloping behind him, and a violent explosion occurred.

Thundered~!

-602！

Spell Combo!

Spell Combo x1!

As for the other two, they went directly behind the fire demon, and soon after the first two flame bombs exploded, the two flame bombs behind him also exploded directly, and the fire demon's backward impact was immediately canceled out, and he roared directly and threw a lot of fireballs towards Ye Qingcheng.

"It's a bit slow." Ye Qingcheng frowned slightly, the effect he needed was to hit at the same time, not such a relay-type combo.

After thinking for a moment, Ye Qingcheng once again blasted out four flame bombs. This time, he didn't separate the four flame bombs as soon as he came up, but let the four flame bombs fly into the air at the same time, and then swooped down, only then did he group up in twos and twos, one after the other, and blasted towards the fire demon over there.

Thundered!

-2297！

Spell Combo!

The flame bombs on the front and back sides of the side exploded almost at the same time, and the poor flame demon, under the squeeze of the impact runes on the front and back sides, flew directly to the left like a cannonball, almost hitting the anti-monster Zhang Crooked over there, so frightened that this guy quickly shrunk his neck.

"I'll rub it, what's going on with you?" Zhang over there glanced at the monster crookedly, looked at the ice-blue flames burning on it, and immediately realized that this must be Ye Qingcheng's ghost.

"Ahem, mistake, it's a mistake." Ye Qingcheng coughed dryly, he didn't expect that this kind of oolong would appear when he hit the front and back, otherwise, he wouldn't dare to play like this even if he was killed.

But then again, the reason why this flame demon got out of control was mainly because Ye Qingcheng had some mistakes in the previous operation, and there was a little deviation when he was aligning before and after.

But then again, who can control the landing point so accurately when attacking? What's more, Ye Qingcheng is a mage, and the attack distance is basically thirty or forty meters away, and the difference of a star and a half is simply not visible at such a long distance. Therefore, it is obviously unrealistic to want to have no deviation at all when you combine the front and back.

For a while, Ye Qingcheng's practice seemed to have reached a dead end, and there was no hope of success at all. Ye Qingcheng knew that now was a very critical period for him to come, which was equivalent to a hurdle, and he was bound to be able to enter a new level and reach unprecedented heights.

And if he can't get through, then for a long time, his strength will be stagnant, and he can't think of any improvement.

Ye Qingcheng frowned, obviously a little painful for such an abnormal situation.

"What are you thinking?" At this time, Bing Xue Yingying over there seemed to see Ye Qingcheng's distress, and walked over with brisk steps, looking up at Ye Qingcheng.

"Well, a question in the experiment... It's just not going very well. Ye Qingcheng simply went through his bottleneck and ice and snow, this girl's brain is flexible, her skills are not bad, and she is also a mage, so she may be able to give Ye Qingcheng a little new ideas.

"Hmm... Since you can't hit back and forth, why don't you try to hit back and back and left and right together? Bing Xue Yingying over there didn't have a good way, so after thinking about it for a while, she suddenly spoke.

"Front, back, left... Give it a try. "To tell the truth, Ye Qingcheng has not thought of this method, but the front and rear combined attacks need to take care of two directions, and the required operation is much higher than that of ordinary combined attacks, and the combined attacks of the front and rear left and right sides require higher operations than the front and rear combined attacks. In this case, even if he really succeeds in the experiment, due to too much operation, the number of consecutive combo attacks will inevitably be reduced.

If it is not necessary, Ye Qingcheng really does not use this way to carry out a combo.

But now there is no other way anyway, so why not try Bing Yingying's proposal, maybe in the process of experimentation, what new inspiration will be obtained?

Fire Charge! Fire Charge! Fire Charge! Fire Charge!

Ye Qingcheng once again blasted out four flame bombs and blasted towards the flame demon, but this time because the operation was too cumbersome, one flame bomb hit the target in advance, and under the effect of the impact rune, the remaining three flame bombs all lost their accuracy.

The experiment failed!

Ye Qingcheng was slightly stunned, but he was not discouraged, and once again blasted out a large area of flame bombs, but the difficulty of controlling four flame bombs in a row was too high, and this time he still failed to hit the target.

The experiment failed!

The experiment failed!

The experiment failed!

I don't know if it's because the difficulty is too high or what the reason is, Ye Qingcheng tried it several times in a row, and even used a third-level flame bomb to directly consume the poor flame demon alive, but there was still no success.

"Damn, I don't believe it!" After many consecutive failures here, Ye Qingcheng's temper also came up, and he gritted his teeth and began to practice without saying a word.

The experiment failed!

The experiment failed!

The experiment failed!

Fire Charge! Fire Charge! Fire Charge! Fire Charge!

I don't know how many times he failed, Ye Qingcheng once again mechanically blasted out four flame bombs, and this time I don't know if it was an illusion or what the reason was, Ye Qingcheng only felt that those few flame bombs were very smooth to operate, and they were like commands. In such a brave state, the four flame projectiles descended, and then split into four like female scattered flowers, attacking at the same time from the front and rear effects of the fire demon.

Thundered~!

-3413！

Spell Combo - Quartet!

However, at the moment when the four flame bombs formed a combined attack, a Ye Qingcheng had never seen the system prompt suddenly rise into the air, and before he could react, the fire demon who was hit by the combined attack over there was as if someone had punched him from the ground, and the whole person rose into the air like a tornado, flying four or five meters above the ground, and then he fell to the ground and fell into a state of paralysis.

"! What's going on? Ye Qingcheng didn't expect this to happen at all, and fell directly into a state of confusion.

"I'm afraid that's the real use of spell combos." At this time, Bing Xue Yingying over there suddenly said faintly: "All along, don't you think that spell combinations are almost useless except for combining spells?" ”

Hearing this, Ye Qingcheng also fell into deep thought, and after a long time, he said faintly: "Listen to you like this... It seems that it is. Because of this, quantitative changes cause qualitative changes, the more difficult it is to combine spells, but there is no reason to increase the number no matter how much it is, the effect is the same, right? It seems that we just didn't get the hang of it before. ”

"That's right, and I think that this so-called quadrangular formation should not be the only way to combine attacks, there should be other ways for us to choose." Bing Xue Yingying is also pretty and serious, the square array discovered by Ye Qingcheng is obviously a new field of spell-casting skills, for players who lack a theoretical foundation, if they want to thoroughly study these spell-casting skills, it is completely like crossing the river by feeling the stones, it is really too difficult and too difficult.

Wait a minute! What is the theoretical basis?

Thinking of this, Bing Xue Yingying's heart suddenly moved, looked at Ye Qingcheng, and asked, "You... Will there be any mention of these spell-casting techniques in the system's books? ”

Ye Qingcheng was stunned for a moment, and then immediately reacted, and said in a deep voice: "It is very likely, the books in this world are very evil, and there are many things, which are recorded in the books. In order to get the chapter of the mage, I put a lot of effort into these books. ”

"By the way, didn't you study these books in the first place? Why haven't you seen all those records of spell-casting techniques? Bing Xue Yingying over there seemed to think of something, and suddenly asked.
