The three returned to the dormitory.

"Chen Xuan, you are too majestic today."

"Prince of the dragon clan, you've made him lose his temper."

Qing'er felt a little excited.

Xiaolongnu also thanked: "Chen Xuan, thank you very much."

"Qiong'er, you and I are both envoys to the Human Domain and good friends, this is what it should be." Chen Xuandao.

It seems that because of Qiong'er's affectionate name, Xiao Longnu's face turned red.

But a trace of dissatisfaction rose in her heart: "compatriots, friends...is that all?"

Thinking of this, Xiaolongnu was startled, and immediately calmed down and stopped thinking about it.

.

Back in the room, Chen Xuan thought for a while and decided to enter the Dragon Trial Space.

This time, the Dragon Clan gave him 20 billion yuan of marrow, plus a trial order, which was quite generous.

His gravity field is initially condensed, and can be slowly expanded later... Of course, he may not choose to use the law of gravity as the main law to comprehend. After all, gravity is only the basic law, far inferior to other advanced laws, and more powerful ones. The law of origin.

The greatest significance of the law of gravity to him is to make him familiar with the complete process of comprehending and comprehending the law, so as to accumulate experience and lay the foundation for comprehending the law and using the domain battle in the future.

Therefore, he did not intend to use the two billion yuan of marrow to comprehend the law, but to improve his own cultivation.

In his own cultivation from the mid-level 9th ​​floor of the mortal rank to the peak of the 9th floor of the mortal rank, this does not require much essence... He intends to use all the rest of the essence to expand the external meridians.

The plan has been made, he took out the trial token and entered the dragon body refining trial space.

Seeing Chen Xuan's figure appearing, Ao Kun was not surprised and mocked: "Haha, I'm here to fight the autumn wind again? How many times have I said it, without the trial order, you will never want to enter the advanced trial in your life."

He sneered: "The opportunity for advanced trials is difficult to obtain even for the heirs of the Dragon Emperor. How can it be cheap for you, a human being?"

Seeing him like this, Chen Xuan directly smashed the trial token into his face.

"Don't talk nonsense, start the advanced trial quickly."

Although Ao Kun is a trial guard and will inevitably interact with him in the future, Chen Xuan especially hates him... Even if the relationship between the two is already very bad, there is no need to give him a good face.

"Trial token? Where did you come from?" Ao Kun, who still wanted to continue mocking, was stunned. He picked up the token and looked left and right, with a puzzled look on his face.

"Could it be that you stole it?" Ao Kun frowned.

"If it wasn't for you who could start the advanced trial, you would be the ghost under my sword at this moment." Chen Xuan's eyes turned cold.

"Uh..." Ao Kun was startled, and suddenly remembered the rumors about Chen Xuan.

"There are four kinds of advanced trials, dragon heart, dragon blood, dragon scales, dragon liver, and only one trial order, you can choose one." He was businesslike.

Glancing at Chen Xuan's small body, there was an unnoticeable gloomy look in his eyes.

"Hey, I'm afraid you don't know how painful it is when the strengthening light enters the body... Our giant dragon is still unbearable. You are a little human race, I'm afraid you will die in minutes."

"If I accidentally implant all the strengthening lights into your body...you can't hold back the fainting, and the strengthening lights are all invalid...that's no wonder I."

Thinking of this, Ao Kun sneered.

"Choose Dragon Heart." Chen Xuan said.

The dragon heart represents strength and is the first choice.

"Okay, I'll open the high-level trial avenue for you." Ao Kun said cheerfully.

He used a secret technique and instantly teleported Chen Xuan to a vast hall.

The environment is no different from the previous primary trial... Chen Xuan thought about it and felt that it should be a different monster.

Sure enough, an earth-shattering dragon roar sounded.

A behemoth appeared on the teleportation array.

This is a giant dragon with a length of 400 to 500 meters. Its whole body is burning with raging fire, and every move is a raging fire. The two big eyes are even more red, like two deep flames. Capturing, as if it can capture the soul of a person...

"This is a flaming dragon... There are some dragon-blooded creatures on the primary trial road. I didn't expect that in the advanced trial, all opponents turned into giant dragons, and they were all stronger dragons."

"Since I have such a good opponent, I can't waste the opportunity to sharpen my combat experience."

Thinking of this, Chen Xuan put away the Long Yuanjian.

He used Yuan Li to condense the five elements of shield, and suddenly a thick layer of five-color light shield appeared all over his body...

"war."

Chen Xuan rushed towards the flaming dragon.

Roar!

The flaming dragon's sinuous, huge dragon head twisted violently, opening its fiery blood basin and swallowing it.

Chen Xuan's movement is very fast, like an arrow from a string, and he easily avoided this blow. The man has come to the left side of the giant dragon and is about to punch, but the flaming giant dragon seems to be very sensitive to the surrounding, and it is already in the first place. Time noticed where Chen Xuan was.

He didn't give Chen Xuan a chance to take action at all, the dragon body twisted weirdly, and it was comparable to the huge dragon tail of a hill.

boom!

The speed of the dragon's tail flick was too fast, and Chen Xuan was hit accidentally, and was thrown hundreds of meters before he stabilized his body.

"I'm careless, the power of the three dragons... it's okay."

Chen Xuan flew up again, this time he raised his spirits, guarded against the dragon's tail, and walked around the dragon's upper body.

The shape of the giant dragon is like a mountain, and what he is afraid of is the opponent with exquisite movement, but small size...

And Chen Xuan wandered in the firelight outside his body like a loach, often slipping away before he had time to react, and roared in a hurry.

And Chen Xuan had already taken the opportunity to throw a few punches on him.

At this moment, he has the power of three dragons and a half, condensed the whole body's blood, and when it bursts, he can reach the power of four dragons...

Therefore, although there were no critical hits in these punches, the screams of the flaming dragon were still repeated.

"Roar..."

The flaming dragon was distressed. He was a giant dragon, and was completely at a disadvantage in front of a small human. The dragon's tail-defying blow did no harm to Chen Xuan at all, and Chen Xuan's strength was even greater than himself. ...

With a shield, he is not afraid of fire.

Are you a dragon, or my dragon?

At this moment, Chen Xuan punched again.

But this punch, like the sky pressing down on the top, is so powerful that the dragon has never felt it in his life.

For a split second, the flame dragon just felt that my life was over.

boom.

With just one blow, the flame dragon's body was smashed into hundreds of millions of pieces.

Blossoming fireworks, scalding dragon blood and minced flesh scattered in the sky.

"Advanced trial, there are three-headed monsters in total, the second dragon, please show up." Chen Xuan said lightly.

Roar..

This roar shook the heavens and the earth, like the thawing of the eternal river, and the eruption of a giant volcano that had been dormant for countless years.

A surging and huge coercion swept the entire hall.

Immediately, a huge thunderous roar sounded, and a huge dragon surrounded by endless thunder appeared in front of Chen Xuan with the momentum of Taishan pressing the top.

"Thunder dragon?"

The giant dragon in front of him was covered with thunder light, and countless thick thunder arcs jumped, and even the air was slapped with electricity.

Chen Xuan quickly opened the distance.

His five-element shield can only defend against five-element spells, and has no defense against thunder and lightning... If he is accidentally hit, it will definitely be unpleasant.

"Using the Longyuan Sword is too bullying. In this battle, I will use Zhenyuan..."

"The first battle of Zhenyuan Sword, don't let me down."
