Ye Chen waited in the cave for ten days, and saw that the Fire Raven King in the ancient painting of the Immortal Mansion was quickly exhausted under Xiaoqing's day and night attacks, and he couldn't even stand steadily, so he couldn't help but show a look of satisfaction.

The Fire Raven King didn't know Xiaoqing's "sinister intentions" to keep attacking it.

Its spiritual intelligence is extremely high among demon beasts, but compared to Xiaoqing, it is still 108,000 miles behind. Every time it saw Xiaoqing appear on Xianfu Island, it would fight it with all its might, or open its mouth to shoot a fireball bombardment, but Xiaoqing burrowed into the limestone and easily dodged it.

In just ten days, the Fire Raven King ran out of physical strength in the process of chasing and killing Xiaoqing.

This dangerous and fierce sixth-order Fire Raven King was trapped and died in the Immortal Mansion, falling to the ground and languishing. It was still far from starvation, but its combat effectiveness was greatly weakened.

"You can go in and clean it up!"

Ye Chen felt that it was almost time for him to make a move, and it would be a waste of time to wait any longer. Moreover, new changes may occur outside the cave at any time, and the ancestor of Jindan of the Worship Fire Gate is likely to appear.

He had to eliminate the hidden danger posed by this Fire Raven King as soon as possible and put away the ancient painting scroll.

Ye Chen sealed the entrance to this cave with rocks and several ice walls to prevent other monks from the outside world or fire crows from breaking into this cave.

Subsequently, he turned the ancient painting scroll into an immortal island.

Ye Chen directly entered the Immortal Mansion Island with his physical body.

The Fire Raven King fell on the ground of the island, and when he saw Ye Chen, his scarlet and sharp eyes suddenly showed a wild and fierce color, "Ya~Ya~" screamed, struggling to get up and attack Ye Chen.

Ye Chen's eyes lit up, and he raised his hand to shoot out a cyan cyclone.

"Bang!"

A cyan vine-like spirit rope several feet long and thumb-thick bound a pair of long wings of the Fire Raven King.

His current wood winding technique, a ** thousand pounds of boulders is also pulling.

The Fire Raven King seemed to know that it was about to finish, so he struggled frantically like a return to the light, suddenly broke the vine, and fluttered his wings and pounced towards Ye Chen.

"I still have the strength!"

Ye Chen was taken aback, and quickly retreated.

At the same time, his hands quickly shot out a series of cyan air masses.

Seven or eight winding spells flew over and hit the Fire Raven King, quickly binding the Fire Raven King's feet and wings.

If it had been changed ten days ago, Ye Chen's winding technique might not have even had the slightest effect, and it would have been directly torn apart by the huge force of the Fire Raven King. But now, the Fire Raven King is just returning to the light, using his last strength to fight hard.

The Fire Raven King broke one vine, two vines, and the last of his strength was exhausted, and quickly Ye Chen's seven or eight winding techniques were completely tied to death.

The Fire Raven King was tied to the ground, leaving only his fierce eyes staring at Ye Chen.

After Ye Chen tied it up, he stopped looking at it.

He hadn't thought of what to do with this Raven King. Kill it? Not for now. To deal with it, of course, you have to maximize the benefits and come up with the best way to do it. Anyway, the Fire Raven King has lost his threat, and he is not in a hurry.

Ye Chen walked in the Immortal Mansion, looking at his Immortal Island.

The entire Immortal Mansion, the island that was originally like a fairyland, has already been wreaked havoc by this Fire Raven King's fierce temperament, the Alchemy Pavilion and the Refining Pavilion have almost been destroyed, and there are broken pieces of spirit wood everywhere, collapsed alchemy furnaces, and a large number of ores, which are in a mess.

It made him frown.

"The immortal mansion is not enough to grow elixir. You must arrange a strong defense for your Immortal Mansion! This is just to deal with a sixth-order Fire Raven King. If you encounter such a thing again in the future, and there are more powerful demon beasts rushing into the Immortal Mansion, I am afraid that I may not be able to deal with it as easily as today, like the Heavenly Void Spirit Mansion, arrange a demon Ten Thousand Sword Array on the island, and if a demon beast breaks in, it will be killed directly!"

Ye Chen said secretly.

Of course, he couldn't do this for a while. Arranging a giant sword formation on Xianfu Island is too expensive, and it is not something that can be done in a short period of time. Plan slowly in the future.

Xiao Qing walked around the Fire Raven King, jumped on the top of the immobile Fire Raven King's head and stepped on it a few times, it was full of pride, "Dare to scare me!

Ye Chen glanced at it, shook his head with a faint smile, and came to a giant fire crow's nest in the Immortal Mansion.

The fire raven's nest was not destroyed by the Fire Raven King. The Fire Raven King probably wanted to use this immortal mansion as his territory and settle down here, so he didn't destroy his fire crow nest.

"Xiaoqing, what can this fire crow's nest be used for, and what is the difference between it and the beast pen?"

Ye Chen said curiously.

Xiaoqing jumped down from the top of the Fire Raven King's head, and quickly came to the side of the Fire Raven's lair, looking at the nest with a strong interest.

It hadn't seen a nest before.

"The fire crow's nest should be used to hatch fire crows! It shouldn't be much different from the beast pen, but any spirit beast in the beast pen can be raised. Since this is a fire crow's nest, I'm afraid I can only raise fire crows! Try it and you'll know, I'll let these fire crow eggs hatch in the fire crow's nest!"

After Xiaoqing finished speaking, he put thirteen fire crow eggs into the nest. Previously, in order to prevent the Fire Raven King from being hungry and eating these Fire Crow Eggs, these Fire Crow Eggs were moved out of the Immortal Mansion by Xiaoqing.

Soon, thirteen fire crow eggs in the fire crow's nest cracked open, and from inside hatched a small fire crow hatchling that was waiting to be fed.

"They need to eat spiritual food to grow!"

Xiaoqing came to the side of the one-acre field in the Immortal Mansion again, and planted a large number of spirit valleys in the field. The Spirit Valley seeds were all ready-made, and the low-level Spirit Valley that Ye Chen planted in the Heavenly Void Immortal Gate was very suitable for raising spirit beasts. Spirit beasts eat a lot of food and often need a lot of spirit valleys. Linggu is easy to plant, and ordinary Lingtian can usually be harvested once a year.

It doesn't take so long in the Immortal Mansion, a large amount of infusion is full of spiritual energy, and the spiritual valley of the spiritual field grows rapidly, blooms, forms grains, wafts out bursts of spiritual valley aroma, and can be harvested soon.

Xiaoqing fed these spirit valleys to the thirteen young fire crows in the fire crow's nest.

Raising large fire crows is different from wild fire crows. The wild fire crow is too wild and is classified as a demon beast, and it is extremely difficult for the Terran monks to domesticate. However, the raised fire crows belong to spirit animals and can obey the command of the monks.

Ye Chen watched from the sidelines, thinking that he could raise a group of fire crows in the Immortal Mansion, and his heart was extremely excited.

He'd seen the power of the fire crow with his own eyes. Although the strength of a low-level fire crow is ordinary, the strength of hundreds or thousands of fire crows is extremely terrifying, and with extremely high spiritual intelligence, it is even enough to defeat the same number of monks with excellent cooperation.

Take, for example, the more than 1,000 treasure hunters of the Earthflame Mountain and the thousands of fire ravens on this hill.

The fire crows are all fire type, they are extremely organized, and they absolutely obey the command of the fire crow king. The fireballs they shoot at the same time form explosions and the power of the sea of fire can be stacked. Thousands of fire crows opened their mouths at the same time and spat out a fireball, covering a range of thousands of zhang, and the power was even more terrifying than the high-level spell Fire Rain Technique of the Jindan monks.

In contrast, a thousand treasure hunters, though numerous, looked strong. However, the monks have many spiritual roots, and the spells they practice and the magic weapons they use are too messy. This monk cultivates water-based spells, but that monk cultivates fire-based spells, and the effect is completely opposite. If they work well together, they can certainly play a great role. However, the battlefield is too chaotic and without a leading monk with sufficient prestige, it is often difficult for the treasure hunters to form a joint force among themselves. Don't talk about cooperation, it's good not to pull each other's back.

Because of this, the thousands of fire ravens on this hill had an almost one-sided advantage, crushing the hundreds of monks who had gathered here. Ten days have passed, and I haven't seen the other seven or eight hundred treasure hunters from Earth Flame Mountain come to the rescue.

The treasure hunters trapped in the caves of this hill did not expect other treasure hunters to come to their rescue. If you want to wait for reinforcements, you can only wait for the Jindan monks from the Great Immortal Gate, such as the Fire Worship Gate and the Heavenly Void Immortal Gate, to come.

"If you can have such a group of fire crows, your strength will immediately increase dramatically!"

Ye Chen clenched his fists and suppressed the excitement in his heart.

This will be one of the strongest killer tools he can wield. The magic weapon of the Immortal Mansion cannot be used at will, but he can release a huge flock of fire crows from the Immortal Mansion to fight the enemy. Not to mention the enemy in the foundation building period, even if he encounters a strong enemy of Brother Jindan, he also has the capital to fight.

"The crux of the matter now is how many spirit stones it costs to raise a fire crow! This determines how many fire crows can be raised. A flock of fire crows can only be powerful if they are large enough, and too few will not work. ”

Ye Chen thought secretly.

Xiaoqing was busy feeding the thirteen fire ravens in the fire crow's nest.

Ye Chen also grabbed a few handfuls of Linggu and threw them towards the fire crow's nest.

In just one hour's effort, the thirteen young fire crows in the fire crow's nest began to grow rapidly, from young fire crows with no combat effectiveness, to first-order inferior, then first-order medium, and finally to first-order high-grade fire crows.

Their size has also changed from the size of their fists to the size of a one-foot fire crow. They flew out of the nest and competed for the Spirit Valley that Xiaoqing had fed them.

A first-order high-grade fire crow is equivalent to the strength of a third-level cultivator in the early stage of qi refining, and these thirteen fire crows have already formed the combat power of a small fire crow team. Together, these thirteen first-order fire crows are estimated to be able to defeat a Qi Refining Stage ** level cultivator.

Ye Chen saw the large consumption of spirit stones in the Immortal Mansion, and quickly calculated it, his face was happy.

On average, a first-order high-grade fire crow eats the Spirit Valley cultivated in the Immortal Mansion, and the cost of the Spirit Valley is one hundred spirit stones.

Feeding these thirteen young fire crows into a first-order high-grade fire crow cost a total of 1,300 spirit stones.

To raise a hundred first-order fire crows, it costs 13,000 spirit stones.

1,000 first-order fire crows, 130,000!

He can still accept this cost.

However, the strength of the first-order fire crow is too low, even if there are many of them, the strength is not enough. When encountering a monk in the foundation building period, the first-order fire crow is the share of being slaughtered. Even if there are many of them, it is useless, because the vitality of the first-order fire crows is too weak, and a single wind blade can kill them.

"Xiaoqing, feed them to the second, third, or even fourth order. I'll see how many spirit stones need to be consumed. ”

Ye Chen thought for a moment and said.

The fourth-order fire crow belongs to the foundation building level, which is equivalent to his cultivation strength.

Xiaoqing nodded immediately.
