Xiaoqing continued to plant the Spirit Valley in the Immortal Mansion Field, and used the Spirit Valley to feed the thirteen fire crows in the fire crow's nest. As these fire crows grow, they rise in rank and become larger, and their food consumption increases rapidly.

Among the thirteen fire crows, there are three fire crows that are particularly fierce in grabbing food. They are slightly larger than the other fire crows and are more ferocious, often driving the weaker fire crows aside to snatch food.

Every time Xiaoqing fed them Linggu, these three fire crows always grabbed the most food, obviously a few percent more than the other fire crows.

Even, these three fierce fire crows will fight with each other, and when the fight is fierce, they even use sharp pecks and claws to tear other fire crows, and the fight is covered with scaly wounds.

Seeing this, Ye Chen was worried that they would be disabled, so he wanted to intervene, but after thinking about it, he held back.

It is the nature of spirit birds to grab food, and he can manage it once or twice, but it is impossible to stare at them every day. In case one or two heads are really killed in the rush for food, the loss can be borne and there is no need to stop it.

It takes some time to feed the fire crows.

Ye Chen went out from Xianfu Island, took Xianfu Island into his body, and asked Xiaoqing to slowly raise fire crows in Xianfu.

He then opened the ice wall and rock that sealed the cave and went to the other caves to investigate.

It's been ten days, and it's time to go and see how the other monks are doing.

Leaving the cave and walking in the grotto passage, Ye Chen soon found several corpses of Qi Refining Stage cultivators, all of which were killed with one blow, and it seemed that they were probably killed by the wild Fire Raven King ten days ago. The storage bags and other items on their bodies have not been turned over and have remained in their original condition after death.

Ye Chen took off all the storage bags on them.

After that, he walked four or five more cave passages, but the situation of the exploration was very unoptimistic.

There were no less than a few corpses of Qi Refining Stage monks left in each cave, and most of the wounds were left by the fire crows. There are also a very small number of monks who have sword scars on their bodies, and they are killed under the spirit sword and spirit sword.

Ye Chen squatted next to these corpses and carefully examined the injuries, as well as the items on their bodies. It was found that the gourds containing the spirit wine in the storage bags of these corpses, and the pill bottles containing the Bigu Dan were empty. As for spirit stones, elixirs, and the like, there are many more.

"Most of the monks ran out of Bigu Dan and Spirit Wine, and were killed by the fire crows, but a small number of monks also had internal fights, taking each other's belongings. ”

Ye Chen's heart was awe-inspiring.

It was no surprise that the treasure hunters were forced to rush and snatch each other's precious spirit wine and Bigu Dan.

More than seventy or eighty foundation building and qi refining stage cultivators had been trapped in this fire crow hill by thousands of fire crows for ten days. He searched only four or five caves, and found the bodies of several monks. Judging from the number of deaths, in just ten days, these seventy or eighty monks are afraid that more than half of them have died.

Not many monks survived.

Shocked, he didn't go any further.

The enemy now is not just the fire raven of this hill, it is likely to encounter a monk who maliciously robbed. Once encountered, most of them will have to clash, fighting for the remaining spirit wine and Bigu Dan.

Reinforcements from the Worship Fire Gate and other immortal gates did not appear.

Ye Chen was a little disappointed, but he knew it very well. From the time the news spread to the arrival of reinforcements, just ten days was simply not enough. If the Heavenly Void Immortal Sect sent a large group of monks to come, it would take a month or two to say the least.

The fire crow swarm still seals the entire fire crow hills.

Ye Chen followed the original path, retreated to the original cave, and resealed the cave with a big rock.

For the time being, I couldn't leave this fire crow hill, so I could only continue to wait.

He opened the ancient painting scroll and checked the feeding situation of the thirteen fire crows in the Immortal Mansion.

One of them, a fierce fire crow, was the first to advance to a second-order fire crow, nearly doubling in size.

It kept flapping its thicker wings and cried excitedly, making it very powerful in this small group of fire crows. After it broke through the second order, it immediately pounced on the other two fierce fire crows that had been robbing it before, and its ferocious wings flapped and knocked them down.

The two fierce fire crows couldn't fight it, and they all surrendered and lay down.

The other ten fire crows were even more obedient, and did not dare to compete with it for food.

Subsequently, the spirit valley that Xiaoqing threw at them, it was always this fire crow that ate first, and it ate the most. After it had eaten nearly a fifth, it cried at the other fire crows, and the other fire crows dared to come forward and eat the rest of the spirit valley.

If this fire crow did not cry, the other twelve fire crows would not dare to come forward.

Moreover, the two fierce fire crows eat more, and those weaker fire crows eat less.

This small flock of fire crows gradually appeared to be clearly divided into different levels. The second-order fire crow, the largest in size, had clearly become the leader of this group of fire crows. Fire crow flocks show a high level of intelligence and will distribute food appropriately within the house.

Ye Chen was a little shocked when he saw this scene.

"Out of this small group of fire crows, there was a fire crow king automatically! two fierce fire crows second only to the fire crow king, and ten slightly weaker ordinary fire crows. ”

That's a good thing, though. Fierce fire ravens are found in flocks of fire ravens, and they tend to be more ferocious in battle. Just from eating, you can see the obedience and cooperation between the fire crow flock, which is difficult for other low-level spirit beasts to do.

Xiao Qing continued to feed this group of fire crows, and it took half a day to feed them to the third order.

After the birth of the Raven King in the Raven's Lair, there was less fighting within the Raven Flock. The Raven King will control the fight within the Raven Group to avoid casualties.

Ye Chen silently calculated the cost.

Feeding a fire crow to the third-order upper strength costs about nine hundred spirit stones. The thirteen third-order fire crows had consumed a total of more than 10,000 spirit stones for him, and the spirit stones stored in the Immortal Mansion were almost exhausted.

Is this investment worth it?

A third-order high-grade fire crow is roughly equivalent to a ninth-level cultivation in the Qi refining period.

You must know that among the more than 1,000 treasure hunting monks who entered the second layer of the Earth Flame Mountain Cave, there were only dozens of foundation building stage monks, and the rest of the thousands of monks were below the ninth layer of the qi refining stage.

The strength of the third-order fire crow was already able to compete with ordinary late-stage Qi cultivation cultivators.

Broadly speaking, this cost is very low.

Ye Chen thought in his heart.

"Master, do you want to let them break through the fourth order? However, breaking through the fourth order is estimated to have some risks. ”

Xiao Qing fed them to the third order, then stopped and asked.

The first order to the third order are qi cultivation level spirit beasts. Breaking through the fourth order, it is a foundation-level spirit beast, and its strength has skyrocketed. However, it is difficult to break through.

"What risk?"

Ye Chen was surprised.

"Each race breaks through an important bottleneck and has different risks. The Fire Raven race relies on feathering to complete the ranks, as you can see. ”

Xiaoqing shook her head.

"Okay, let the Fire Raven King break through the fourth order first!"

Ye Chen pondered for a moment and said.

Xiao Qing nodded, drove the other fire crows away, and only fed the fire crow king of this group of fire crows.

In the Immortal Mansion, to control the growth rate of the spirit beast, as long as the food is controlled. Without enough food, spirit animals can't grow.

In addition, not all spirit animals can continue to grow. This is also closely related to the racial qualifications of spirit beasts.

The spirit porcupine that Ye Chen had raised before belonged to an extremely ordinary type of low-level demon beast. An ordinary adult spirit porcupine is a first-order superior strength, and if it can reach the second order, it can be called the porcupine king, dominating in a porcupine forest.

Ye Chen fed his Spirit Porcupine to the third order, which was already outrageously high, and the subsequent promotion space was extremely small, even if he ate a large amount of Spirit Grass, it would be difficult to ascend. Ye Chen didn't plan to let the porcupine continue to be promoted.

In contrast, the racial qualifications of the fire crows were obviously much stronger than those of the porcupine, ordinary fire crows could reach the third order, or even the fourth order foundation building level, and the fire crow king could even reach the sixth order - this was the strength of a group of fire crows that Ye Chen had seen in this fire crow hill. It's hard to say whether the fire crows in other places can be higher.

Xiaoqing fed the Raven King a lot.

The third-order Fire Raven King ate excitedly, and his body continued to grow, reaching a full nine feet, almost growing to the limit, and stagnating his growth.

However, it is still eating a lot, as if it is not full, and it is accumulating energy. Its body became fat and muscular, and its fiery feathers became more and more reddish.

Half a day later, it finally stopped eating.

Ye Chen looked at it with some pain, in such a small half a day, it had eaten thousands of spirit stones in the Spirit Valley, more than before.

Seeing that it was no longer eating, Xiaoqing stopped and looked curiously.

The fire-colored feathers on the Raven King's body began to fall off one by one, shedding their feathers, and a layer of skin on the pecks and claws began to fade.

But only a small part of it was dropped, and there were many feathers that were not dropped.

Seeing that it could not fade, the Fire Raven King picked up a Fire Raven Bloodstone in the Fire Raven's lair and poked at its own unfallen feathers.

"In the process of blood and feathering, if the fire crow bleeds too much, it will die. The whole must be done all at once, and if it is interrupted, it will also lead to the failure of the breakthrough. ”

Xiaoqing was a little nervous.

The Fire Raven Bloodstone was extremely sharp, and it stabbed the Fire Raven King's body and suddenly stabbed blood, and the Fire Raven King felt a sharp stinging pain, but he did not let go, and stabbed several times before a few feathers were removed.

This is just the beginning, and it still has a lot of feathers to fade all over its body.

The fire crow king took the fire crow bloodstone in his mouth and poked it at his body, first the feathers, the scaly wounds all over his body, dozens of hundreds of blood stains, and then the unfading skin on the pecking and claws, grinding on the bloodstone, grinding off the layer of skin on the pecking and claws, and tearing it off alive.

The Raven King was in great pain, but he didn't even make a call. As soon as it opens its mouth to call, the Raven Bloodstone will fall from its mouth. No one knows if it will have the courage to pick up the bloodstone again.

This process shocked even Ye Chen, a bystander.

The Terran monks need to build the foundation in order to break through the bottleneck of the foundation building period.

The Fire Raven didn't use any Dan, but the process of breaking through the fourth order was even more bloody and amazing.
