"Ten?"

Xia Yun was taken aback, and he also knew that in addition to the True King Spirit Core, there were also a large number of Heavenly Spirit-level and Holy Spirit-level elixirs, which were also what he wanted very much, especially the Heavenly Spirit-level and Holy Spirit-level nerve strengthening elixirs, which could not be bought with money.

Now, Xia Yun finally knows why the nerve enhancement potions are restricted, it turns out that the production process is very complicated, and it is not something that ordinary people can do.

To become a Saint Martial Spirit Master, a Heavenly Spirit-level nerve strengthening potion is indispensable.

After the battle of the beast tide, Xia Yun's moon spirit space has long been without the soul of the earth spirit beast and the earth spirit core, especially the earth spirit core, but it can't be taken out, in a sense, he is still very poor and poor.

Since the first place in the Hidden Dragon Cup can get a lot of enhancement potions, he naturally won't miss it.

The first place belongs to him, and no one can snatch it!

Since the beast souls in the moon spirit space are sufficient, and even the state of being stuffed, there are as many as 30,000, and it is also the first time that Xia Yun realizes that the moon spirit space is a bit small, and he still thinks it is a bit big at the beginning, so for the next period of time, he no longer needs to hunt spirit beasts to obtain beast souls.

The first place in the Qianlong Cup had the enhancement potion he wanted, and Xia Yun naturally didn't need to think about the spirit core.

How to make himself stronger is Xia Yun's top priority.

The growth of the spirit takes time, and Xia Yun is not in a hurry to do this.

In this way, the only thing that can make Xia Yun stronger is combat skills.

There is not much time left before the start of the Qianlong Cup.

"Alright, let's go down. ”

General Zhenyan watched the sun set and reminded him.

"Good!"

Xia Yun said a little excitedly.

I have to say that learning from the people of the Tianyan Legion has benefited Xia Yun a lot.

The journey to Hongdu is still a bit far, thousands of miles away.

Before you know it, it's less than a month away from the Qianlong Cup.

At this time, Xia Yun's Heavenly Martial Spirit had already grown to adulthood and become an intermediate Heavenly Martial Spirit Master, if it weren't for the limitation of the absorption efficiency of the bone strengthening potion, he would have been able to break through to a high-level Heavenly Martial Spirit Master long ago.

Because of this, Xia Yun urgently needs the reward of the first place in the Qianlong Cup.

As for the Heavenly Demon Spirit, he has also grown to adulthood, but if he wants to grow to the peak, he needs Xia Yun to tame another demon beast, in fact, he can now have five demon beasts.

The Heavenly Soul has also grown to adulthood, but without the Heavenly Spirit-level spiritual enhancement elixir, Xia Yun will not be able to become a high-level Heavenly Soul Master for the time being.

With enough beast souls and spirit cores, Xia Yun's three spirit growth is like flying.

Xia Yun estimated that the beast soul and spirit core in the Moon Spirit Space were enough to support him to become a powerful high-level spirit master, or even a junior true spirit king.

Although the 30,000 beast souls were not all earth spirit beast souls, only half of them appeared, but Xia Yun carefully calculated that these beast souls were enough to fuse more than two thousand heavenly spirit beast souls, or more than two hundred holy spirit beast souls.

Of course, in order for Xia Yun to become a junior True Martial Spirit King, he also needs three True King Beast Souls, which cannot be solved by relying on the fusion souls of the Moon Spirit Space.

"It's here!"

Suddenly, General Zhenyan's voice rang in Xia Yun's ears.

Xia Yun came back to his senses in an instant, his eyes looked in the direction that General Zhenyan was pointing, and his eyes widened suddenly, and his pupils were filled with indescribable shock.

A tall city came into Xia Yun's eyes.

That's really tall!

The city wall alone is 100 meters high.

Some of the walls are scarred, some are brand new, and they all tell the story of their history and glory.

This city is the imperial capital of the Tianhong Empire -

Hongdu!

Even from a distance, Xia Yun can still see clearly the architectural style in the city, which is a bit similar to the modern earth, with many high-rise buildings.

From General Zhenyan's mouth, Xia Yun learned that the population of the city exceeded 10 million, and because of this, high-rise buildings could allow more people to live in the city.

Now, Xia Yun has a certain understanding of the three northern kingdoms.

The Three Kingdoms of the Northern Frontier are like three major lines of defense, forming a stable habitat for human beings.

The imperial capital of the Three Kingdoms in the North, although it is the most prosperous and powerful, is also the most dangerous, and the people here need to face the most powerful spirit beasts.

In fact, the area occupied by the three northern regions is only about one percent of that of the northern border.

The Tianhong Empire is located to the east of the northern border, with the Chiling Empire to the west and the Beiyu Empire to the north.

General Zhenyan told Xia Yun that to the east of the Tianhong Empire, there was the Tianhong Great Rift Valley, and there were spirit beasts in that place that were more powerful than the True King Spirit Beasts, such as the Earth King Spirit Beast and the Heavenly King Spirit Beast, so he told Xia Yun not to go to the Tianhong Great Rift Valley.

Between the Tianhong Empire and the Tianhong Rift Valley, there is an ancient forest with a radius of thousands of miles, called "Tianhong Ancient Forest", the name of the Tianhong Empire, hence the name.

Most of the resources of the Tianhong Empire were obtained from the Tianhong Ancient Forest.

However, there were a large number of True King Spirit Beasts in the Tianhong Ancient Forest, so the True Spirit King powerhouses such as General Zhenyan did not dare to go deep into the land of the Tianhong Ancient Forest.

Every three years or so, the three major legions of Hongdu have to resist a terrifying beast tide, and the new and old traces on the city wall are enough to show the horror of the beast tide.

Because of this, Hongdu is a place where opportunities and dangers coexist, rather than the most stable place for human beings.

In fact, on the Four Spirit Continent, there has never been a truly stable place for human beings, even the extremely powerful Northern Spirit Sect is no exception.

In this world, spirit beasts are the real masters.

In a sense, human beings are just in the world of spirit beasts, desperate to survive.

Just when Xia Yun was thinking, the Burning Sun Eagle had already landed outside the city gate of Hongdu.

General Zhenyan jumped down and led the men of the Tianyan Legion to the city gate.

Xia Yun hurriedly came back to his senses, then withdrew the Sun Eagle and followed.

Under the leadership of General Zhenyan, Xia Yun entered the city smoothly after a long corridor, and even had the illusion of returning to Earth for a moment.

Of course, it's just the architectural style, and the way of life, which is still very classical, at least not too much mechanization.

"Catalpa tree, you can arrange Xia Yun's residence. ”

With that, General Zhenyan broke through the air.

"Yes. ”

Before the words fell, a young man came to Xia Yun and said with a slight smile: "Welcome to join the Tianyan Legion." ”

This young man is the Catalpa tree, with a burly body, as his name suggests, as tall as a tree, he is one of the great commanders of the Tianyan Legion, a powerful senior saint martial spirit master.

Along the way, Xia Yun is familiar with the people of the Tianyan Legion such as Catalpa Shu, and he doesn't know each other if he doesn't fight, especially Xia Yun's combat effectiveness is very strong, and he has been recognized by Catalpa Shu and others.
