In addition to some terrain that is the key point, this big formation has another key point, that is, the person who presides over the formation.

"This battle connects the underground dragon vein and is full of spiritual power. All you need to do is to mobilize the power of the spiritual array and deal with the Dragon Empire. I will help you from the side. Just let go and kill the enemy." Lu Heng reminded.

Long Xuan and Jiang Zhiyao looked at each other and nodded.

Lu Heng was teaching by his side, patient and meticulous, for fear of missing a key point. This spiritual array is huge and complicated to operate. Every magic seal must be taught in place, otherwise one step will be made mistakes and one step will be made.

Fortunately, Long Xuan and Jiang Zhiyao are very smart, and Lu Heng just taught them and learned them.

"You fight me."

Lu Heng used a Wu King experience card, and his aura instantly increased to the peak of Wu King, and started a practical battle with Long Xuan and Jiang Zhiyao.

Before the third level, a terrifying combat power rippled out, instantly shaking the entire third level.

Countless soldiers guarding the pass looked up and looked forward, their eyes were full of awesomeness. This terrifying fluctuation suddenly changed their color. This was so terrifying.

The clear sky suddenly faded, dark clouds covered the sky, and a terrifying aura suppressed the sky and could not be emitted.

The roof is covered with dark clouds, and there are black thunder in all directions. The world is vast, and there is only a terrifying aura that is surging and may fall at any time.

"this."

The end of the world seemed to be coming, and everyone was uneasy, and the soldiers guarding the pass felt even more like they were sitting on pins and needles and faced with the abyss.

"Is this Lord Lu?"

"Why does it feel like Lord Lu is stronger than last time?"

"Miss Long and Miss Jiang!"

Many soldiers exclaimed, their eyes full of surprise and disbelief.

"How is this possible!"

The earth cracked open, and the dark clouds in the sky were immediately dispersed, and a burst of blazing light burst into the sky.

Lu Heng was floating in the nine heavens, and he did not dare to underestimate the terrifying power.

"Taiyi Xuantian Sword!"

Lu Heng shouted loudly, and a giant sword floating above his head appeared. The giant sword spread across the sky, with a suffocating breath that instantly crushed.

With a bang, the Taiyi Xuantian Sword fell, and it took a while to make it below.

The blazing light was blocked and did not fall.

Long Xuan and Jiang Zhiyao also squeezed cold sweat. If Lu Heng was really hurt, it would be a serious crime.

Lu Heng landed on the ground, glanced at the two of them, and said, "Continue to practice."

"yes!"

Long Xuan and Jiang Zhiyao both looked solemn and did not dare to neglect them.

Lu Heng took Long Cang back to the city wall, and Long Cangtian shamelessly leaned over again.

"Master, when can I teach me how to manipulate this spiritual array?" Long Cang looked excited.

"Manipulate the spiritual array? I think you want to make those top-quality spiritual stones. These pieces are for you." Lu Heng spoke and threw the spirit stones to Long Cang.

When Long Cang saw this spirit stone, his face was filled with excitement.

"Practice well, don't forget, you are not even a martial artist now." Lu Heng said angrily.

Long Cang couldn't wait to swallow the top-grade spirit stone, and a force floated out of his body in an instant. Then, light burst out from his body. In an instant, Long Cang stepped into the realm of the martial arts master.

Lu Heng was stunned.

Although the dragon vein is unique, the cheating is obvious. The martial artists have to fight and sacrifice it and practice step by step. He can't help but swallow a few spirit stones and break through directly.

"It's now." Long Cang smiled.

"Are you sure that practicing like this will not affect your future practice?" Lu Heng asked.

"What are you afraid of? How many people come? Haha, I want to come more!" Long Cang laughed excitedly.

Soon, Lu Heng figured it out. This guy was the unique dragon vein. Although he was forced to stay in Cangyue Pass when he left the ground, his body was like a dry dry well.

Now, as long as there is a rain from the sky and fill the dry well, he may recover to his peak in an instant!

"I still think that you can practice step by step. Although you have lost the Dragon God and Dragon Yuan, this may not be a chance given to you by God. If you practice again, you may go further and higher." Lu Heng taught.

At this moment, Long Cang seemed to have realized something and thought a lot in his mind.

"Thank you for your advice." After a long time, Long Cang nodded slightly, as if he had figured out something.

Lu Heng nodded slightly.

At this time, Li Zhong walked up with a sharp look and bowed his hands and said, "Sir Lu, the city defense has been arranged properly, please accept it."

Lu Heng knew how much he had, but he didn't understand how many pounds he had. Li Zhong had followed Gu Chang'an for the rest of his life and was better than him, a naughty young man.

Lu Heng is not a strong person.

"In this regard, you can just make arrangements. I have a premonition that the Dragon Empire will launch a surprise attack soon and tell the soldiers of the city defense to keep a close eye on them and never let go of any wind and waves. In addition, the surrounding mountains on all sides of the third level should also be set up secret whistles. If there is any strangeness, there will be a warning for wolf smoke." Lu Heng said.

"yes!"

Li Zhong nodded.

The atmosphere of the entire third level was not relaxed at all. After a big battle, the soldiers became more warlike after a little repair.

This surprised Lu Heng a little.

I have to say that Gu Chang'an is really good at leading troops. Even if others leave, this guy's energy remains in the army. There can be said that there is no coward in the entire third level defender.

Everyone is a veteran of all wars, and he is ready to die.

As night fell, a fire that soared into the sky was emitted from the ruins of the second level. In the flames that soared into the sky, a mast seemed to slowly erect, and on the mast was a corpse.

"Look, they hung up General Gu's body again!"

"asshole!"

The soldiers' eyes were red.

Gu Changan is undoubtedly their favorite general. At this moment, Yan can't be angry when she sees the other party treating Gu Changan's body like this.

"The Dragon Empire is so cheap. Any damage can be used." Li Zhong punched the wall.

"It's just to disrupt our morale."

"But this approach is really hard to swallow!"

The two Kings of Martial Arts gritted their teeth and found it difficult to calm down.

This was a great insult to them and was simply unbearable.

Lu Heng looked up at them, and there was a fire burning in his eyes. Gu Changan was his sixth disciple, and doing so would be too disrespectful to him.
