Outside the protective cover, Liu Zhengyang held his breath and held the Blood Dragon Spear tightly in his hand.

At the same time, the blessing of Daoyin slowly merged.

This blow is undoubtedly the most powerful blow that Liu Zhengyang can deliver.

Maybe the people inside were guessing whether Liu Zhengyang's blow could break the shield, but Liu Zhengyang knew very well that he was curious about how long the shield could last under this shot!

It's not that Liu Zhengyang is boasting.

With his ability, not all Daoyuan realm powerhouses can send it out.

After all, the ancient blood king is a living example.

Moreover, the positioning of the city defense system is to defend the design of low-level life and soul. If there is really a strong Taoist source, it will put too much pressure on the protective cover.

At that time, there will also be special people to deal with the powerhouses of Daoyuan Realm.

But you also have to prevent the opponent from jumping over the wall, and you need to take certain countermeasures.

This defensive power must be available, even if it is not used!

Liu Zhengyang's eyes became sharp, the blood dragon spear in his hand shook suddenly, and then the air burst out, piercing directly above the protective cover with a whistling sound.

"boom!"

The shield shook suddenly.

With the help of the wood seal, the fire seal increases its power out of thin air.

The flames hit the protective cover like a rainbow that pierced the sky, and continued to impact the protective cover.

In the current state, Liu Zhengyang has not been able to perfectly integrate the gun mark and several other Dao marks.

This also caused him to be unable to exert his most powerful strength now.

The protective cover began to shake desperately, and this shaking also made the machine inside the protective cover start to make a warning sound desperately.

This is still quite a deadly situation for a shield.

Tang Yuting and the others suddenly changed their expressions.

They didn't expect Liu Zhengyang's attack strength to reach such a level, which was far beyond their expectations!

"Kakkaka!"

With the fine cracks covering the entire protective cover, in the last whistle, the protective cover suddenly shattered.

Not only that, the machine that had been recording the data also burst open and crashed!

Black smoke rose up inside the machine, and Liu Zhengyang couldn't help laughing when he saw this scene.

But fortunately, he was watching when he attacked. Although he didn't pull back in the end, the attack just hit the cliff in the distance!

Even if it is consumed layer by layer by protective cover.

Liu Zhengyang's blow is still shocking.

Above the cliff, the rocks began to shake, and finally fell to the ground.

Finally, with the sound of collapse, the cliff finally collapsed.

Fortunately, the distance is relatively far, except for some dust floating over, there is no other problem.

"What about this?"

Liu Zhengyang couldn't help but spread his hands when he looked at the smoking computer.

"It's okay! We have backed up the key data!"

For this kind of thing, Tang Yuting already has complete emergency measures, and there is no panic at the moment.

Liu Zhengyang smiled and nodded: "This is not bad! The strength of the protective cover is indeed good, but if the city defense system explodes after being attacked, it will not work!"

Liu Zhengyang frowned and said, "Even if his protection is weaker, the service life of the city defense system must be guaranteed. Even if it is blown to pieces, it can still be restarted in a short time!"

The reason why Liu Zhengyang said this is to take into account the sneak attack of the Daoyuan realm powerhouse. If he can continue to use it, it will continue to effectively block the black soul!
