Liu Xuan's retreat this time can be regarded as the longest one since he went to Taijimen, more than three months of retreat, more than 100 days, more than 3 months, he almost spent all of his time in the immortal space, the outside of the 100 days, in the immortal space, there was nearly a year, this year, Liu Xuan's split landslide finally became a small success, this was originally the physical technique of the transformation of the pulse level, if it were not for Liu Xuan's physical body far beyond the ordinary transformation of the pulse level, I am afraid that he would not be able to withstand the power of the splitting landslide at all.

Cracked landslide, there are only two layers of exercises, one layer of cracked stones, two layers of landslides, the cracked stones here, in fact, is just an adjective, but the mountain, is not an adjective, once cultivated to the strength of the mountain, it is really possible to open the mountain and crack the stone, it is said that if the cracked landslide is completed, in the face of the fifth-order spell moving the mountain, the cracked landslide has a fight.

The second is the hybrid spell, the power of the split landslide remains to be seen, but the power of the hybrid spell Liu Xuan knows in his heart, the power of the hybrid spell is far greater than the ordinary second- and third-order spells, because it is his three-color giant wheel, its power is even more powerful than the fourth-order spell, and in a specific environment, it is even comparable to the fifth-order spell.

The only drawback is that the casting speed of the hybrid spell is too slow, with Liu Xuan's current level, the second-order spell is almost instantaneous, and the third-order spell is a little worse, but it can be done in a breath or so, unless there are some particularly strong third-order spells.

But the hybrid magic method is not, because it is Liu Xuan's three-color giant wheel, even if it is to extract the spiritual power within the Heaven Turning Seal, it still takes more than ten breaths of time, compared to the three-color giant wheel, the Flame Thunder Dragon is faster, but it also needs at least two breaths of time, so, most of the time, Liu Xuan's Flame Thunder Dragon and the three-color giant wheel can only be used once, this is not only due to the limitation of spiritual power, but also the main reason is the problem of casting speed, when the opponent knows the casting speed of your two powerful spells, it is absolutely impossible to let you cast it casually。

When the split landslide was a little successful, Liu Xuan shifted the focus of refining to the hybrid spell, he now set a very high goal, below the qi condensation level is not his goal, his goal is at least to turn the pulse level, if it is against the upper pulse level, it is difficult for ordinary second- and third-order spells to cause significant damage to the opponent, the same casting speed, if you use the second-order spell, the pulse level can use the third-order spell, you use the third-order spell, the opponent can use the fourth-order spell, so, to deal with the strong of the vein level, except for Bai Liu Xuan to go up to fight in close combat, but the strong man of the vein level may not give you a chance to get close, even if you have the fast step and fireburst technique in hand, Not all the vein transformation levels are not free of speed, if you encounter a vein-type vein again, it will be difficult for Liu Xuan's hand-to-hand combat to produce results.

At the beginning, the experiment was not smooth, the flame thunder dragon is different from the fire thunder, the fire thunder is only a temporary fusion of the two attributes of gold and fire, in order to ensure its stability, so the integration of the two series of elements are relatively stable, and it is precisely because of this that the detonation of the fire thunder takes a certain amount of time, and it is precisely because of this delay that although the fire thunder is huge, the fire thunder is destined to become an unexpected killer, but it cannot become Liu Xuan's killer move.

The Flame Brontosaurus is different, this two-attribute mixed element is extremely unstable, so it must be released at the moment the Flame Brontosaurus is formed, but it is precisely because of the instability of the elements that the power of the Flame Brontosaurus is so amazing.

Liu Xuan can fuse the two attributes of gold and fire, but he has no way to control these two unstable elements, because once the elements are stable, it will be like fire and thunder, and it will take at least one delay time, but if it is unstable, he can't control it.

Because when using the Flame Thunder Dragon, it is to directly extract the spiritual power in the Burning Xia Seal and the Falling Thunder Seal, these two spiritual powers are not only abundant, but also have a balanced proportion when extracting, but Liu Xuan can't, first of all, there is not so much golden and fire dual-attribute spiritual power in his body, so he needs to be drawn from the outside world, but the golden fire spiritual power in the outside world cannot be as balanced as the Burning Xia Seal and the Falling Thunder Seal.

This is easy to understand, just like if you are at the water's edge, whether it is a river or a seaside, your water aura recovery speed must be better than that of other attribute aura, and the spirit fruit is at the edge of the woods, and the wood aura must be far better than other spiritual powers.

In almost all places, the golden spiritual power must be weaker than the spiritual power of other attributes, even if you are in a metal mine, the golden spiritual power is on par with the earth spiritual power, unless you are in a completely enclosed metal space, even then, the fire spiritual power in the air will not be much worse than the golden spiritual power.

Therefore, if you extract gold spiritual power from the outside world, it is destined to be impossible to have the same speed as fire spiritual power, and if you want to maintain a balance, unless you have the dual-purpose method of the old naughty boy Zhou Botong, otherwise, you don't want to let the two spiritual powers be balanced and fused.

This is a contradiction, if you want to create a flame thunder dragon, you must make the two spiritual powers balance and fuse, but you can't do this, but if you want to stabilize the fire spirit power and then fuse the gold spirit power, the generation after the fusion is fire thunder, even if it is not fire thunder in form, but it is destined to have a delay, and the result is still fire thunder.

Therefore, if you want to achieve the same proportion of fusion effect on both sides, it is not just a casual control, at the beginning, either there is more fire spiritual power, or there is more gold spiritual power, and the result is needless to say, when one of the spiritual powers is extremely stable, it is directly exploded, and the first time it was even worse, Liu Xuan actually directly blew himself into a serious injury, if it wasn't in the immortal diagram, I'm afraid he wouldn't be able to get up, but fortunately, it was in the immortal diagram, his recovery ability was greatly enhanced, Liu Xuan lay on the ground for two days before he got up and did the test again, but fortunately, after the first experience, Liu Xuan put his own weapons tightly when he fused again, although there were countless explosions after that, but he finally didn't almost blow himself up like the first time.

Liu Xuan found a valley in the immortal space, and experimented in this valley, at the beginning, the monkey of the Red Flame Mandrill was still with him, but after Liu Xuan's experiment failed a few times, the monkey was killed and was not here, this valley became a forbidden land, no animal was willing to come here, at the climax, there were more than a dozen explosions here every day, and in the end, a valley was blown up into a desert, and the original lush valley became a bare valley, and in the valley, there was not even a single grass more than a foot long。
