Under Jon's complaint, Zhang Yi and Viana learned:

Originally, the dark dragon clan could not easily step into the territory of the bright dragon clan.

Only recently, there was a loophole in the protection system of Longyuan City, which led these black dragons to stare at this loophole and take the opportunity to constantly invade Longyuan city!

So far, this is the 10th batch of invaders defeated by Longyuan city!

Hearing this, Viana was worried and asked, "how can this vulnerability be repaired?"

Jon said, "the energy crystal of Longyuan city has guarded Longyuan city for thousands of years. It is almost exhausted. You need to borrow some energy from other cities."

Each main dragon city has an energy crystal to protect the city from arbitrary invasion by the enemy.

Once the energy crystal is exhausted, if the energy is not injected again as soon as possible, the city will lose its protection system.

Viyana also understood the importance of the matter: "if you borrow energy, you need to take Neng Jing to other cities, but once there is no Neng Jing in Longyuan City, it is easy for the enemy to take advantage of it."

"Yes."

Jon sighed and said, "this has always been my biggest concern."

"If I take Neng Jing to other cities, when the enemy invades, the Longyuan city will be unattended. If it is attacked by the dark dragon clan, the gain will not be worth the loss."

Hesitated.

At this time, Viana said, "I'll go for you. You stay and defend the city, if you believe me..."

Unexpectedly, Jon seemed to be waiting for vyana's words and said without hesitation, "OK! Of course I believe you, Nana!"

"You help me take Neng Jing to other cities. I'll stay and guard Longyuan city. It's so good!"

Of course, Viana did not forget that she came to Longyuan city to meet Jon. In addition, she also wanted to help Liuguang city through the crisis of ghost invasion with Jon's help.

However, this situation is happening in Longyuan city now. If you don't repair the loopholes for Longyuan City, Jon will certainly be unable to leave Longyuan city to support Liuguang city!

In this regard, Jon has long made a plan he has no chance to implement:

"The main city of the bright dragon family, the Futian city. It was conquered and occupied by the black dragon three hundred years ago. The Neng Jing in the city stopped running three hundred years ago. If you can get the energy in the Neng Jing in the Futian City, you can make the Longyuan city run normally for at least another three hundred years!"

"The energy crystals in the dog day city have been sealed in the city. You can only use other energy crystals to extract its energy, not from the dog day city."

Obviously, Jon has gone to voodoo.

And there is only one way to get the power of energy crystals in the city of Futian: take the energy crystals of Longyuan city to the city of Futian, absorb energy, and then bring the charged energy crystals back to Longyuan city!

At this time, Viana said, "OK, I'll take the energy crystal of Longyuan city to Futian city to obtain energy."

Jon looked grateful. "Thank you, Nana."

At this time, Viana also said her unkind request: "just... After that, can you do me a favor?"

"The ghost clan reappears. The human streamer city is about to be invaded by the ghost clan. I hope you can help the streamer city and repel the ghost clan!"

"Ghost clan, isn't it sealed?" Joan was incredible.

However, he did not hesitate and immediately said, "no problem!"

So, without delay, we began to prepare immediately.

In order to ensure the safety of Viana and Zhang Yi, Jon sent a 100 person dawn dragon knight to escort them.

In addition, vyana and Zhang Yi are all four rank dragon emperors!

Jon takes out the energy crystal of Longyuan city and gives it to Viana.

"Be careful and wait for your triumph!"

After taking Nengjing, Viana and Zhang Yi rode the fourth order Dragon Emperor and led the dawn dragon riding regiment to leap into the far air!

Only when Viana has just left the field of Longyuan city with Neng Jing of Longyuan city.

The huge protective barrier shrouding Longyuan city immediately disappeared.

Dark intrusion.

In the far air, it seemed that countless eyes were staring at Longyuan city.

There are more than dark dragons coveting Longyuan city.

Countless monsters with strange shapes, as well as the black dragon lurking nearby, approached Longyuan city one after another

In Longyuan city.

Jon, the dragon warrior, drew his sword and shouted:

"The soldiers of Longyuan City, resist the enemy with me!"

On the other side, Zhang Yi and Viana left Longyuan city.

Looking back, I saw the original brilliant Longyuan city. After losing Neng Jing, it seemed to fall into the dark abyss in an instant.

There was lightning and thunder in the air, and dark forces invaded Longyuan city.

"We must come back immediately with energetic energy crystals!"

As Viana's voice just fell, Zhang Yi nodded: "HMM."

So they hurried to [dog day city]!

A full two-hour trip!

When Zhang Yi and Viana arrived at Davos Heavenly City, it was already dark.

It's very different from the glorious scene in Longyuan city.

Although it is also the main city of the dragon family, the Futian city was occupied three hundred years ago, and the dark dragon family later withdrew from here.

Today, it has become a social place for all kinds of mountain gods and wild monsters.

The gray castle, located in the dark flat ground, looks very lonely.

Zhang Yi and Viana, leading the Dragon cavalry regiment, flew down to Tiancheng.

But I found that there was silence in such a big city!

Viyana, who is located in the city, picked up the staff and toured around: "don't take it lightly, always be on guard!"

100 dawn Dragon Knights, on standby.

At this time, Viana took out the energy crystal.

The energy crystal of Longyuan city can directly sense the energy crystal power in the dog day city.

At the moment when Viana took out the energy crystal, countless blue light spots gathered from all directions and flew into the energy crystal!

In just one minute, all the energy in the dog day city will be absorbed by the energy crystal!

The originally dull energy crystal seemed to recover its vitality in an instant, and its appearance was faintly twinkling with bursts of blue light!

But this process is smooth, which makes people feel a little incredible.

"How can you get the energy of Futian city so easily?" a knight of dawn dragon riding regiment said suspiciously.

Viyana put away the energy crystal and said, "return immediately!"

As they prepared to sail back to Longyuan city.

Boom boom!

Floating in the air, a huge dark cloud came out of the illusion, and lightning grew from it.

At the same time, an ethereal voice came from the dark cloud:

"Is the dog day city a place where you can come and go if you want?"

"I've been waiting for you here for a long time!"

The voice just fell.

Countless huge black crows flew out of the clouds and straight towards viyana and them!

At this time, viyana was shocked: "Oh, we're in ambush!"

In all directions, a group of dawn Dragon Knights drew their swords and rode on the dawn war dragon.

Roar!

The roar of dragons resounded through the city of Futian.

"Dawn dragon riding regiment, ready to fight!"

Meanwhile, the other side.

Liuguang city.

As night fell.

In the air, suddenly lightning and thunder.

A huge skeleton cloud that makes people familiar appears in the air!
