The thunderball flew to the Beast King Mountain, and with a roar, thousands of demon beasts gathered.

For a while, under the Beast King Mountain in the Youlan Realm, a strange scene appeared.

Countless demon beasts, like a tide, slowly gathered and gathered at the foot of the Beast King Mountain.

At a glance, tigers, leopards, birds and beasts, all kinds of monsters, all kinds of monsters, all kinds of strange, some can't even be named.

A group of young people from the Mangshan tribe immediately rushed into the group of beasts excitedly, touching and pinching these demon beasts.

Roar!

These demon beasts are all wild wild demon beasts, how can they bear to be treated like this, and immediately some demon beasts let out an angry roar.

Howl!

The thunderball immediately let out the beast king's cry and subdued these demon beasts.

In the end, these demon beasts only dared to roar and demonstrate to the people of Mangshan, and did not dare to really open their mouths to bite.

Among the generals of the Mangshan Army, the younger heads ran in to select.

Some like tigers and leopards, some like eagles and falcons, and some like strange-shaped monsters.

Of course, it's not up to them to decide which monster to pick.

After all, the cavalry to be formed in Mangshan is the Jiaolong King Cavalry.

Therefore, the demon beasts to be selected, even if they can't defeat the Sky Splitting Dragon, they can't at least be too bad.

And the Sky Splitting Dragon was selected by the Void Royal Clan from hundreds of millions of demon beasts, and in the extraterritorial void, there were really not many demon beasts that could defeat the Sky Splitting Dragon.

Of course, directly choosing an ancient divine beast like Kunpeng will naturally be able to crush the Splitting Sky Jiaolong.

However, if it is a cavalry to be formed, then there is a hard condition for the selected demon beasts, that is, they must be able to form a scale.

Not to mention 100,000, there will always be 20,000 or 30,000.

And the primeval Kunpeng, it is already a miracle to be able to meet one or two, and it is impossible to form a Kunpeng cavalry of twenty or thirty thousand or thirty thousand. New debut m..

Therefore, the selected demon beasts must not only be strong enough, but also need to be large enough, and it is best to live in groups, so that there will be a tacit understanding when they cooperate.

Ye Xuan and Qin Tai'a released their divine thoughts at the same time, observing these demon beasts.

The divine thoughts swept through them one by one, and those whose rank was lower than the saint-level demon beasts were directly skipped, and the remaining number was actually not much.

Ye Xuan asked the thunder ball to let go of all the demon beasts below the holy level, and in the end, one percent of the demon beasts remained.

After all, most of the demon beasts are actually low-level demon beasts, and there can be one percent of the demon beasts above the saint level, which is already a very large number.

Next, it's time to choose from these one percent of demon beasts.

After the hierarchical filtering, the next step is the quantity filtering.

All groups with less than 10,000 numbers will be screened out.

Then there is the body size, some of which are small monsters, only the size of a palm.

Even if this kind of demon beast is not weak in combat, it does not have the foundation to be trained as a cavalry, and it is also screened out.

After passing through the selection of various selections, there are finally three monsters left to choose from.

They are the saber-toothed mane lion, the four-clawed Jiaomang, and the green manglong eagle.

Next, it is necessary to carefully test which demon beast is suitable for training into cavalry.

After some inspection, the first to be excluded was the saber-toothed lion.

Because the habit of the saber-toothed lion is that a male lion leads a group of female lions, although it is a group of demon beasts, the female lion is not as strong as the male lion.

If the saber-toothed male lion is trained as a cavalryman, the male lion can only be selected from among the young lions and slowly domesticated.

The saber-toothed male lion domesticated in this way can indeed be used against the Jiaolong King Rider, although it may not be able to win, but it will not be too bad.

But tens of thousands of saber-toothed lions are actually easy to mess up and very troublesome to domesticate.

And to start raising lion cubs, it takes a long time to complete domestication.

Therefore, the saber-toothed male lion can be domesticated as a lion ride in the future, but it is not suitable as the main force against the dragon king's ride.

The saber-toothed lion was ruled out first.

Immediately afterwards, the four-clawed Jiao was also ruled out.

Because the four-clawed Jiao Mang happens to be the lower demon beast of the Split Sky Jiaolong, when he encounters the Split Sky Jiaolong, he may be scared off without fighting.

Therefore, the four-clawed Jiao recklessness is also excluded.

In the end, only the last type of green mango dragon eagle remains.

This is an eagle-like demon beast, with an average level of not low, and it can fight against the Sky Splitting Dragon.

Although the number is not tens of thousands, it has reached seven or eight thousand, and the number is enough.

The only drawback is that it's too ferocious.

The Qingmang Dragon Eagle is indeed very fierce, and whoever dares to approach will immediately claw.

Without special methods, it is very difficult for this bird of prey to train as a cavalryman.

This is the reason why the Dragon King Rider can become the overlord of the extraterritorial void.

The Youlan Realm is already a holy place for demon beasts, and it is almost impossible to find a demon beast here that may compete with the Dragon King, and it is even more difficult to find it in other places.

Luckily, though, there was a thunderball.

No matter how fierce the Qingmang Dragon Eagle is, in the face of the high-ranking primeval Kunpeng, it can only bow its head.

Therefore, as long as there is a thunderball, it can subdue the Qingmang Dragon Eagle and train it into a cavalry.

In the next month, the Mangshan Department began to train the Qingmang Dragon Eagle in the Youlan Realm.

Of the 8,000 green manglong eagles, only 5,000 were suitable for training.

The number of 5,000 is a little less, but you can continue to breed and domesticate, and you can also go to other places to catch the green mango dragon eagle.

Therefore, quantity is not an issue.

Whether it can be tamed or not is the key.

Under the pressure of the Beast King of the Thunder Ball, these Qingmang Dragon Eagles did not dare to hurt people, but they would never give in.

After a month of trying, it was finally found that only those who defeated the Qingmang Dragon Eagle head-on could be recognized by the Qingmang Dragon Eagle and ride on their backs.

Among the 100,000 elites of the Mangshan Army, they can still find 5,000 warriors whose strength is better than that of the Qingmang Dragon Eagle.

After a month of attempts, the Five Thousand Dragon Eagle Green Cavalry was finally formed.

However, this Dragon Eagle Green Cavalry can only be ridden on its back, and there is still some distance away from cooperating with the battle, and it needs to continue training.

Of course, it's not training in the Netherlands.

Because the Demon Dragon Aogu had already fled back to the Abyss King City a month ago, and there was no need for him to return to the Abyss King City, as long as the news came back to the Abyss King City, the Yelin King would definitely send a large army to attack the Youlan Realm to encircle and suppress the Mangshan Division.

With the marching speed of the Void Royals, it would take almost two months to reach the Nether Realm.

Demon Dragon Aogu will inevitably send the news back to the Abyss King City before returning to the Abyss King City.

Therefore, in two months at most, the army of the Void Royal Clan will be slaughtered to the Netherland Realm.

If you want not to be tracked, the Mangshan Department must leave the Youlan Realm in advance, and leave a month early, which is a relatively safe time.

In fact, Ye Xuan had already asked Mangshan to activate the Star Flying Array and leave ahead of schedule, leaving only the elite of the Mangshan Army to train the Qingmang Dragon Eagle in the Youlan Realm.

Now that the Dragon Eagle Green Rider has taken shape, it's time to leave.

Early in the morning of this day, five thousand dragon riders and eagle green horsemen rose into the air and flew towards the extraterritorial void, leaving the Youlan Realm and entering the boundless void.
