As soon as Tian Ao and the others appeared, Xuan Zhen, as if he could foresee it, controlled countless killing formations and concentrated attacks to hit their positions hard.

Fire Meteor, Gengjin Qi, Void Blade, Tiangang Storm...

The most powerful attack among them is undoubtedly the Geng-Gold Qi emitted by the fourth-level formation 'Earth Mother Geng-Gold Formation' controlled by the metallic formation spirit!

Faced with an attack that was comparable to the combined attack of two to three hundred king-level warriors, the kings of the Tianlong Clan were horrified and desperate.

Who can stop such an attack? Even a fourth level king like Tian Ao will only die.

After all, they never imagined that Xuanzhen could use the resources accumulated by the Baize clan for thousands of years to form so many formations at once, and even launch attacks together!

"Interesting, can the spiritual energy of heaven and earth be mobilized in this way?" Tian Ao was greatly inspired by the process of activating various fourth-order formations.

Faced with this almost fatal attack, Tian Ao actually still has the mind to observe the formation method?

The other kings were helpless, but did not want to sit still and wait for death, so they used their best efforts to set up energy barriers.

Tian Ao's eyes were extremely excited. He got a lot of inspiration from the formation method, and he had a clearer idea of ​​how to break through the fifth level.

"I will definitely be able to break through within twenty years!"

Seeing the powerful attack so close at hand, Tian Ao spit out a ball of dazzling golden light. The light emitted immediately surpassed the light of the sun star and became the most eye-catching existence in the world!

A wild aura that seemed to come from the beginning of the world swept across the world, and the formation attacks that blasted towards Tian'ao and other dragons were as vulnerable as snowflakes in front of the golden light, and quickly melted away.

The situation where Tian'ao and other dragons were destined to die was immediately resolved.

"What? What is this? It can easily resist the attacks of dozens of fourth-level formations and thousands of third-level formations!" Xuanzhen and Xuanluo were in disbelief, staring at the golden light.

At this time, the golden light dissipated, and the things spit out by Tian Ao revealed their true colors.

It was a thousand-foot-sized dark golden scale with mysterious natural lines all over it.

"Ancestral Dragon Scale!" Feeling the boiling of their own blood, all the heavenly dragons immediately recognized its origin.

Since the reunification of the Dragon Clan a thousand years ago, they had never seen Tian Ao take out this Dragon Ancestral Scale. They didn't expect that they would see it again today.

Tian Ao's face was a little pale. It was obvious that activating this Dragon Ancestral Scale was very draining on him. Even if he tried it a few more times, he wouldn't be able to sustain it even with his cultivation level.

After all, these are the scales of an innate god, and cannot be activated by a small king.

"Retreat."

The defensive ability of the dragon ancestor scale owned by Tian Ao is unrivaled in the world. At least no one in the king level can break it, but it is a pity that it has no offensive ability.

Faced with Xuanzhen, who had many fourth-level defense formations and a favorable geographical position, Tian Ao had nothing to do with him. Therefore, after resisting the attack of the formations for half an hour and still unable to find a flaw in Xuanzhen, Tian Ao could only order

retreat.

However, during the half hour of the battle, Tian Ao carefully studied the various formations. With his eyesight, he also saw some of the mysteries and gained a lot of inspiration. Tian Ao's trip was already worthwhile.

Similarly, after trying several formation attacks but unable to deal with the kings of the Tianlong clan who were protected by dragon scales, Xuanzhen could only let Tian Ao and his party leave.

This battle finally ended in this way.

Soon, the outcome of this battle spread to all ethnic groups in the south at an extremely fast speed, shocking countless ethnic groups.

"Another top group is born!"
