Yiqiē is very smooth, and it was the previous experience that helped Luo Feng.

But the residual undead magic is really not enough, not only in quantity, but also in quality.

The Bat Ghost Emperor evolved into the Kurosawa Bat Ghost Emperor, although it was also the same as crossing the ninth level, evolving from a tenth-level undead creature to a nineteenth-level undead creature, but this is a ritual for the emperor to evolve into an emperor, and the undead magic power required obviously needs more support.

From the smoothness at the beginning, to the difficulty in the middle, to the hardship at the end.

It is clear that the rate of evolution is decreasing, and the change that is being reborn is being hindered.

The blood red of the Blood Saint Ze is still there, although it is a little light, but the undead magic power it has is still enough, and the speed of the vortex is still the same, not too fast, but definitely not slow.

In this way, there is obviously enough energy.

However, the Bat Ghost Emperor below pulled his mouth and screamed in dissatisfaction and unwillingness, as if urging his master to tell Luo Feng that it still needed more energy, more and more advanced energy.

Luo Feng was so anxious that he became impatient like an ant on a hot pot, and he was almost interrupted even singing.

Quickly took a few deep breaths, suppressed the impatience in his heart, stabilized the urging of magic, and let the blood saint Ze continue to give birth, slowly changing the physique of the Bat Ghost Emperor, even though it was as slow as a snail crawling, but it was finally better than nothing.

However, if the real problem is not solved, it is still difficult to pierce this layer of window paper, so that the Bat Ghost Emperor can really take this step.

The Undead King and the Undead Emperor, if the biggest difference between them and ordinary undead creatures is probably the soul fire!

The King of the Dead is pale gold. The Undead Emperor is all golden. And compared to the turquoise soul fire of ordinary undead creatures. It seems to be fundamentally different.

Among the Blood Saints, countless death war elephants were sacrificed, and the undead magic power contributed was quite sufficient, at least it was definitely enough for the Bat Ghost Emperor to evolve. And what is really missing is the help of the golden soul fire. Even if there is no all-golden Undead Emperor, if there can be a pale golden Undead King as a sacrifice, it should be possible to break this restriction and allow the Bat Ghost Emperor to make a real breakthrough.

King of the Dead. Luo Feng still had some in his hands, but he had used the Death War Elephant as a sacrifice at the beginning, so where could he change it at this time. Luo Feng had no choice but to set his eyes on the only Death War Elephant King, but his expression was very entangled. The Death Elephant King still has a role, its style is very different from the Skeleton Horse King, and it can form a good complement, which is a very useful mount.

If the Death War Elephant King was really contributed as a sacrifice, and the White Plains Elephant Land made Luo Feng sweep away, it would mean a short period of time. Luo Feng no longer has the Death War Elephant as a mount.

What's more, there is already the last one left of the Death War Elephant. If you really want to throw it in, if you can't change the situation, it will be a heavier loss.

Luo Feng simply gritted his teeth, threw the two bat ghost kings he had just enslaved into them first, and then drove the secret technique to kill the bat ghost kings, so that the two pale golden soul fires became nourishment and were replenished into the blood saint.

These two Bat Ghost Kings were enslaved by Luo Feng when he enslaved the Bat Ghosts, but because the Death War Elephants were not enough, they did not let them evolve, but chose to let the Bat Ghost Emperor evolve first. Who knows, the evolution of the Bat Ghost Emperor was blocked, so Luo Feng directly took the two Bat Ghost Kings as sacrifices.

Such a whim, but with unexpected benefits.

Everyone is a bat ghost, and the soul fire can be said to be of the same origin, and it is the pale golden energy of the undead king, which immediately gave the bat ghost emperor enough benefits. It's a pity that the level of the Bat Ghost King is too low, so the effect is only for a while, and it can't last too long.

But it was enough, and Luo Feng, who was inspired, immediately lit up his eyes.

Luo Feng controlled the entire Blood Sacred Mountain, and in addition to enslaving all the Kurosawa Bat Ghosts for a total of 12,000, there were also four Kurosawa Bat Ghost Kings who were successfully enslaved by Luo Feng.

Kurosawa Bat Ghost King, pale golden soul fire, or seventeenth-level undead creatures, and four more!

If you sacrifice four Kurosawa Bat Ghost Kings, you can get one Kurosawa Bat Ghost Emperor, and it is also a trade that will definitely not suffer losses. What's more, this is the mutant Kurosawa Bat Ghost Emperor, and he has the ability to hit with a blood spear, which is even more profitable!

Luo Feng immediately gave an order, and the four Kurosawa Bat Ghost Kings flying outside the Blood Holy Mountain were summoned, and immediately flew to Luo Feng's side, and under Luo Feng's order, they were sent to death without hesitation.

A Kurosawa Bat Ghost King immediately threw himself in, and the pale golden soul fire that had been digested was completely absorbed by the Bat Ghost Emperor.

A hint of gold is cast in the red, and a faint layer of golden light is also dyed in the red light.

The Bat Ghost Emperor was roaring, screaming, struggling at the same time, rotting and shedding his skin, and the seemingly painful process was connected to Luo Feng through guò's spiritual power to let Luo Feng know that it was very good, and it was extremely excited and happy.

After the Bat Ghost Emperor completely absorbed the Kurosawa Bat Ghost King, Luo Feng did not hesitate to invest in the second Kurosawa Bat Ghost Emperor.

This time, the gold is thicker, and the bat ghost emperor's cry is more majestic.

The Blood Saint Ze was suddenly shocked, the whirlpool collapsed, and the red light instantly converged, and the blood red in the Ze water was as if it had met a natural enemy, and it was quickly swept away, as if a large hole appeared in the Blood Saint Ze, which was specially used to absorb the blood red part.

After just a moment, the blood color was gone, and the Blood Saint Ze calmed down.

There was no blood, no glow, no whirlpools, everything was restored to its original state.

In front of Luo Feng's eyes, Kurosawa was the same as before, just like when he first saw it. Calm, without waves, as if bottomless, but there is a sense of transparency in the black.

A qiē, all restored to the original.

Luo Feng's feet were weak, and he suddenly sat down on the side of the Blood Saint, but his expression was unprecedentedly relaxed and happy. He raised his head slightly, and the corners of his mouth couldn't help but hook a smile, until the smile got bigger and bigger, and he couldn't help it, and suddenly it became a crazy laugh.

Boom!

The water splashed in all directions, and a rapid black shadow flew out.

It's the Bat Ghost Emperor, no, it's supposed to be called the Kurosawa Bat Ghost Emperor now!

The two Kurosawa Bat Ghost Emperors, one was originally enslaved, and the size was super-large, and the whole was an enlarged version of the Kurosawa Bat Ghost, with great strength and volume, flying in the sky, more like an eagle than a bat. The other one is a mutant that evolved from the Bat Ghost Emperor.

The new Kurosawa Bat Ghost Emperor is very different, its appearance and appearance are the same as the average Kurosawa Bat Ghost, and its size is not large, so it doesn't look as scary as the old Kurosawa Bat Ghost Emperor. But when it comes to real combat effectiveness, the new mutant is undoubtedly stronger, although its size is much smaller.

Luo Feng laughed for a while, but began to be distressed again.

The two Kurosawa Bat Ghost Emperors don't seem to be very easy to distinguish, and it seems that they need to be given a name.

"Why don't you call it 'Red Thorn'. Luo Feng got up and pointed to the new Kurosawa Bat Ghost Emperor and said. The so-called Red Thorn, of course, also alludes to the fact that it is a mutant with the special ability of a blood spear strike.

The new Kurosawa Bat Ghost Emperor "Red Thorn" screamed and began to circle around Luo Feng, seemingly liking it very much.

Luo Feng was stunned, what does it mean, does it understand that this is its name, or that it has begun to have a certain amount of wisdom, so it understands its own words!

This surprise immediately startled Luo Feng. (To be continued......)
