After some planning, Gu Lin decided to give the ghost baby poison herbs first.

Because the ghost baby had already turned into a human form, Gu Lin usually didn't take him with him, and let him wander around in Wind Thunder City or even the Ten Desolate Medicine Mountain.

However, although that little guy has taken on a human form and his strength has been weakened a little, he also has the strength of the sixth order of the spirit land, and there are not many things that can threaten him.

Thinking of this, Gu Lin slowly took out the origin of the undead beast.

The ghost baby's body, the ghost underworld yin king taro, seems to have a deep relationship with this undead beast, as long as the origin of the undead beast is in his hands, that little guy will never escape.

Looking at the origin of this undead beast, Gu Lin's face suddenly became a little solemn.

The immortal fruit condensed by a few drops of blood of an undead beast can be worth millions of gold coins, and if there is a real undead beast, that kind of terrifying power Gu Lin is a little unimaginable.

However, according to Gu Lin's guess, a peak undead beast is probably not inferior to the strange things of heaven and earth like the desolate beast.

However, the Blood Flame Worm told itself that the origin of this undead beast was equivalent to the young fetus of an undead beast, and if it wanted to be truly born, it had to absorb a lot of elixir or heaven and earth energy.

Thinking of this, Gu Lin sighed helplessly.

Although he had obtained two or three thousand elixirs from the Medicine Hall, it was still far from enough for Gu Lin.

Breeding an undead beast requires an elixir, a medicine witch worm needs an elixir to advance, a blood flame insect needs an elixir to repair the primordial spirit, and the mysterious bronze ancient stone in his body needs to devour a large amount of elixir.

More than 2,000 elixirs can still be said to be a drop in the bucket!

Moreover, Gu Lin still had to leave more than a thousand elixirs in case of accidents.

After all, he can use the primordial spirit of the blood flame insect to exert the strength of the spirit master, but it will cost more than a thousand elixirs at a time, and Gu Lin can only be used as a hole card at the moment of life and death.

Therefore, looking at the origin of the undead beast, Gu Lin couldn't help but sigh slightly, he didn't have the financial resources to give birth to it at all.

However, Gu Lin suddenly remembered that the Blood Flame Worm had told him that the undead beast was just a general term for those spirit beasts with immortal bloodline, and it did not refer to just one spirit beast.

Gu Lin was also a little curious, what was the name of the undead beast in this origin?

Thinking of this, Gu Lin asked the Blood Flame Worm in his heart, "Can you tell what kind of undead beast this undead beast is?"

The Blood Flame Worm looked at the origin of the undead beast for a long time, shook his head and said, "This undead beast has not really taken shape, and I can't see any clues. However, although there are dozens of undead beasts, even the lowest-level undead beasts are definitely not weaker than the fierce beasts with ancient bloodlines. ”

Thinking of the horror of the undead beast, Gu Lin suddenly had an absurd thought.

The most precious thing on the Spiritual Qi Continent is the spirit vein, and the main material for refining the spirit vein is the spirit core, although the undead beast is the respect of all beasts, but after all, it is also a spirit beast, and it will also produce a spirit core.

It's just that I don't know how terrifying the power of the undead beast's spirit core would be if it was refined into a spirit vein?

"Did you say that the spirit core of this undead beast can be refined into a spirit vein?"

Hearing Gu Lin's bold idea, the Blood Flame Worm's expression suddenly froze, and then he said in a deep voice: "You guy is really bold. Although the undead beast is the honor of the beasts, like the spirit beast, the spirit core in the body can also be used as a material for refining the spirit vein.

And with the powerful bloodline of the undead beast, the spirit vein refined with its spirit core is absolutely powerful, even compared to the heavenly veins in the body of ordinary desolate beasts, I am afraid it is not far behind. The only one that can absolutely suppress it is probably the legendary Origin Heavenly Vein.

However, almost every undead beast has a group of powerful races, and those guys will be rewarded, and if anyone dares to hunt their races to refine the spiritual veins, even if you run to the ends of the earth, they will frantically find you out, and then kill them mercilessly.

In the Aura Continent, there are also some strong people who have the idea of fighting undead beasts for a while, but the end is generally extremely miserable. ”

Hearing the words of the Blood Flame Worm, Gu Lin muttered in a low voice, "Isn't there anyone who has used undead beasts to refine spiritual veins?"

Hearing this, the Blood Flame Worm was slightly stunned, and then said word by word: "That's not necessarily! Although the undead beast is powerful, it is not enough to cover the sky with one hand in the Spiritual Qi Continent." Like some powerhouses who are really standing at the pinnacle of the continent, even if they face a powerful race like an undead beast, they don't have to be too afraid. ”

After speaking, the blood-colored flame in his hand suddenly rose, and a touch of arrogance appeared on the face of the blood flame insect.

"My blood-colored flame is actually the fire of the spiritual vein, and the spiritual core of refining the spiritual vein is taken from a powerful undead beast - the undead blood phoenix bird!"

Hearing this, Gu Lin's body shook violently, his face was shocked, and his jaw was slightly loose.

I have been amazed by the horror of its blood flame, but I didn't expect that this blood-colored flame was actually the fire of the spirit vein, and it was also a spirit vein refined with an undead beast!

Gu Lin now has some understanding of the undead beast, and the Blood Flame Worm actually killed a terrifying undead beast refining spirit vein, what is the origin of this guy?

Thinking of this, Gu Lin's lips trembled and said, "You killed one...... Undead beasts, they didn't settle accounts with you, did they?"

"Settle accounts, although the undead beast is the supreme among the beasts, but are we witch worms easy to mess with? Back then, the undead blood phoenix bird had a grudge against me, and I wanted to keep it, but it didn't know what to do, and was finally killed by me on the spot.

Later, this incident alarmed those old guys in the Immortal Blood Phoenix Bird Clan, but they didn't dare to make a move, and in the end, the matter was over. After all, my status in the Witch Worm Clan is no less than that of the undead beast among spirit beasts!"

Speaking of this, the Blood Flame Worm glanced at Gu Lin's shocked expression, and continued, "Of course, although the level of the Undead Blood Phoenix Bird is also extremely high in the bloodline of the undead beast, it is not yet the peak. If it were those few undead beasts standing at the pinnacle, even I would have to weigh them again and again, and those guys would be the supreme existence among the undead beasts!"

Hearing this, Gu Lin finally nodded abruptly.

Although some of the witch insects he saw had strange effects, their combat power was not comparable to that of powerful undead beasts.

But now it seems that those beings who stand on the top of the witch worm may also have quite terrifying combat power, and they are not even inferior to the strongest undead beasts at all!

Slowly suppressing the surprise in his heart, Gu Lin exhaled lightly, and his gaze couldn't help but turn to the origin of the undead beast.

"Do you think it's possible for this undead beast's bloodline to surpass the immortal blood phoenix bird, is it those peak bloodlines?"

Gu Lin's heart was also full of hope, the bloodline of the undead beast was also divided into three, six, nine and so on, Gu Lin naturally hoped that the undead beast hatched in the future could have the strongest bloodline.

The Blood Flame Worm groaned for a moment and then slowly spoke, "I'm afraid this is unlikely. The undead attach great importance to the bloodline of their offspring, and those undead beasts who stand at the peak are extremely protective of the bloodline of their offspring. The undead beasts of that bloodline will not be allowed to leave the population at all until they reach adulthood, so the bloodline of the undead beasts in this origin should not be too high. ”

Hearing this, Gu Lin couldn't help but sigh in disappointment.

"You don't have to be discouraged, what I said is just a general situation, and I don't rule out the possibility that the peak bloodline undead beast is out. However, even the lowest-level undead beasts are absolutely powerful. If you let out the wind, there will definitely be countless strong people with red eyes to snatch it, you guy don't know what to do. ”
