Bang ~

At this time, the rock dragon Ji'ant had already stood up, and most of his body was wrapped in black chains. Every movement was particularly difficult, but the power of the dragon was not something that ordinary spiritual masters could imagine. A black iron chain as thick as an arm suddenly broke with the support of the rock dragon's huge force.

As the first black chain was broken by the rock dragon Giante and turned into gray mist again, a slight cracking sound also made inside the black crystal in the center of the formation below.

Ang ~

Yanlong Ji'ant let out a loud hissing sound, and the chains on his body began to break one after another. Princess Xiya in the distance saw this scene and showed a look of despair on her face.

At this time, hundreds of rock dragon guards had already rushed towards them. Princess Xiya let out an unwilling roar, and the staff in her hand slammed the ground!

Rumble ~

A huge gap suddenly opened on the ground of the school playground, which swallowed all the demons. Seeing the demons entering the crack on the ground, the Lord Yanlong's face suddenly became ugly.

Obviously, this is a route designated by Princess Xiya for the failure of the plan. If the Nulong plan is successful, then these people can naturally leave here in Jiant, who has become a demon dragon.

But once the plan fails, they can also leave the escape passage excavated underground.

"Don't chase after you." Seeing that the Yanlong Guard was about to follow Princess Xiya into the cracks underground, the Yanlong Master frowned slightly and shouted loudly.

Losing Princess Xiya's control, the Nulong Formation completely lost its effect under the huge force of the Rock Dragon Giante. All the black iron chains collapsed and turned into black mist. The Rock Dragon Giante flapped its wings and flew high, left the ground, and hovered in the sky. The huge black crystal in the center of the formation also completely shattered and turned into useless fragments.

The spiritual patterns that formed the entire slave dragon formation began to shine. After a moment, a muffled sound came up from under the ground. The original location of the rock dragon Ji'ant suddenly bulged a large bag and quickly collapsed, turning into a big pit.

Han Dong's face showed a look of disappointment. He originally wanted to carefully study the slave dragon formation, but unexpectedly, after losing control, the formation would actually destroy itself, which made Han Dong's plan fail and he could not achieve his wish to improve the formation's cultivation.

It seemed that he felt the formation was destroyed, and the rock dragon Jiant, who had been hovering in the sky, fell from the air.

However, after landing, Ji'ant did not walk towards Grand Duke Yanlong, but walked towards the observation deck.

Han Dong looked at Ji'an in surprise and found that the other party's big green eyes were also staring at him.

Soon, Yanlong came to the observation deck, and at this time there were only a few people left on the observation deck, and most of them had already left when Princess Xiya was chanting the magical words.

Ang ~

A loud dragon roar sounded, and Jiant actually lowered his head, bit a scale under his neck and tore it off, and then handed the blood-carred dragon scale towards Han Dong.

When Grand Duke Yanlong saw this scene, his face suddenly changed drastically, as if he wanted to stop it. His lips moved slightly and he sighed heavily.

"Duke, is your Excellency Ji'ant to thank that boy for your reminder?" Li Xuedan, the lord of Longyan City, hesitated.

"It should be." Grand Duke Yanlong stared at Han Dong with a pale face, as if the other party had snatched his most precious item.

Han Dong showed a look of surprise on his face. His eyes did not stare at the scales, but at the remaining blood on the scales. That was the real dragon essence and blood. With it, the effect of the super body-strengthening potion in the future will probably be greatly enhanced!

"Reverse Dragon Scale, Lord Ji'ant actually gave him a Reverse Dragon Scale!" Grand Duke Yanlong roared in his heart, and his right hand couldn't help clenching his fists, and his anger was stuffy in his chest and had nowhere to vent.

The dragon Giante's body is covered with hard scales, each of which is comparable to a defensive spirit weapon. However, what the dragon cares most is the few scales growing against the trend under the neck, which are called the reverse dragon scales.

People with anti-dragon scales can sign an equal combat partner contract with them, and the term of this contract is one thousand years! In other words, people with anti-dragon scales can become a real dragon knight!

Only Grand Duke Yanlong will know this news. Each Grand Duke Yanlong will hand over a reverse dragon scale to the next heir before his death, and at the same time inform the other party of the secret.

It has been more than 900 years since the first Grand Duke of Yanlong and Yanlong Ji'ant signed a combat partner contract, which means that in a few decades, Yanlong Ji'ant will restore its own existence.

Because he has been unable to possess the second reverse dragon scale for a long time, the Grand Duke of Rock Dragon was forced to start studying the formation that uses dragon energy. Although he gained something in the end, he could not be compared with a real dragon knight in any case.

"I originally thought it was because Lord Ji'ant wanted to recover, but I didn't expect..." Grand Duke Yanlong looked at Han Dong, who was a little confused, and the corners of his mouth twitched twice.

At this time, Han Dong was still immersed in the ecstasy of obtaining the dragon's essence and blood, and did not notice the complicated eyes of the Grand Lord Yanlong looking at him, and the expected eyes of Ji'an looking at him.

Although the contract with Grand Duke Yanlong has been around for decades, it does not prevent Han Dong from signing a combat partner contract with it now.

Seeing Han Dong carefully put the reverse dragon scale into the storage space of the prayer drum, Yanlong Ji'ant was silent for a moment, stretched out the dragon claw with only three toes, gently pressed Han Dong's head, and then flew towards Yanlong Grand Duke again.

A emerald green light flashed on Han Dong's body, and the Lord Yanlong's eyes flashed, and he couldn't help but sigh in his heart: "It's a very lucky boy!"

Before leaving, Yanlong Ji'ant used a blessing spirit technique to Han Dong. The only effect of this blessing spirit technique is that once Han Dong encounters danger, Ji'ant can feel it and will rush to him to protect him in an instant.

This is a spiritual art that only the dragon knight can enjoy. Now, besides the Grand Duke of Rock Dragon, there is another person in the world who can enjoy this spiritual art.

"I'll leave it to you here. Why can the alien demons set up such a formation in the military academy? Why can they dig out an escape passage? You must find out for me!" Grand Duke Yanlong stared at Li Xuedan and said seriously when he jumped onto Yanlong Ji'ant's back.

Let a hostile force quietly arrange such a large formation in his capital and city, and also dig such a long escape passage. The city lord Li Xuedan is simply a serious dereliction of duty. If it were someone else, Grand Duke Yanlong could cut off his head now.

"Zhu, follow the order, Lord Lord!" Li Xuedan responded with cold sweat on his forehead, and he lowered his head. Obviously, he also understood the seriousness of the matter.

Grand Duke Yanlong took a last look at Han Dong, rode on the Yanlong Ji'ant and flew into the air, and soon turned into a black dot and disappeared.
