In those years when I was a mortal and a demon

The old demon fire monster turned a deaf ear to Lu Yuan's words and disappeared in an instant. Lu Yuan was about to chase after him, but the spiritual energy in front of him suddenly fluctuated violently.

Groups of yellow spiritual light continued to gather, condensed and formed, squeezing toward Lu Yuan's location.

"Formation!" Lu Yuan gave up the pursuit with a sharp look. Taking the crippled Demon Flame duo, they quickly returned to Doctor Mo and the two men.

If they are separated by the formation, Doctor Mo and Dr. Mo will probably fall into the enemy's hands again.

"You have today too!" Li Feiyu rushed forward with a ferocious expression on his face, pressing the ugly man under him.

Perhaps because of being imprisoned for hundreds of years, even though Li Feiyu recovered his cultivation, he still used his hands to strangle the ugly man's neck, which showed that he hated the evil flames so much.

Doctor Mo saw that Lu Yuan's appearance had hardly changed, and his face was filled with relief, but he quickly said with a serious expression: "Don't rush for revenge, this is the territory of the Demon Flame Sect, you can't stay for a long time!"

"It's too late, the formation has already been activated, it's probably difficult!"

"I didn't expect that after so many years of suffering, Master Mo is still so calm." Lu Yuan smiled faintly and looked at Doctor Mo up and down. He is not proficient in the art of battle, and he may suffer harm if he attacks rashly, so the top priority is to protect Doctor Mo and the two of them first.

As for breaking the formation, that's Brother Tiezi's business.

Somewhere in a secret place beneath the Demon Flame Gate, there was a flash of light, and Brother Tiezi's figure appeared.

"It turns out that the formation eye is here. This 'Daoxuangui Formation' is indeed magical. You can't find it unless you open it. It seems that senior brother has already taken action."

"Now that your trap has been exposed, let's see how I defeat you!" A flash of inspiration flashed in Brother Tiezi's hand, and five delicate flags shot out in all directions and disappeared.

Thousands of miles away from the Demon Flame Gate, a blue light escaped. Ancestor Mo Yan's expression changed, and he took out a formation disk from his arms.

"The formation has been activated. The boy named Lu should have already sealed the Demon Flame Gate!"

"So fast?" The face of the Hehuan Old Demon next to him changed.

"Don't worry, fellow Taoist Hehuan, the formation here is passed down from the Tianxing Sect and is known as one of the top ten prohibitions in ancient times. If it were me and my junior brother, we would cooperate with nearly 10,000 disciples to assist. Don't talk about Lu Yuan, even if you are As a great monk, it’s hard to get out even if you’re trapped!”

"That means you are sure to trap him!" Hehuan Laomo was a little excited.

"If fellow Taoist is willing to take action, killing this person will be easy!"

"After the matter is completed, we will share his secrets. As for the treasures, fellow Taoists can choose first!" Demon Flame Ancestor became seductive.

"If we can really use this to discover the secret of transformation, the worst I can do is fly away from home!" Hehuan Old Demon secretly made a decision in his heart, with a glimmer of light flashing in his eyes. His escape speed instantly increased to the extreme and he headed straight for the Demon Flame Gate.

At this time, behind the Demon Flame Sect, the situation of Lu Yuan, Doctor Mo and others was getting worse and worse.

All the scenery between heaven and earth disappeared, and they were trapped in a three-dimensional space about forty to fifty feet wide and more than thirty feet high.

The four walls are shining with yellow light, and the top and bottom of the head are also crystal clear, as if they are made of huge crystal stones, making it look very bright and dazzling.

Lu Yuan tried to scan around with his consciousness, but he couldn't help but frowned and became a little surprised.

As soon as his consciousness came into contact with the yellow crystal wall, it was bounced back, unable to penetrate at all.

"How's it going? Is there any way to get out of trouble?" Doctor Mo asked with a serious look on his face when he saw Lu Yuan frowning.

"Try it." The golden light in Lu Yuan's hand was bright, and a large golden sword light shot out, and the whole space was filled with tinkling sounds.

However, the yellow crystal wall was extremely strong, with no scratches at all, and even the golden light bounced back.

Lu Yuan's expression darkened when he saw this, and he clapped his hands in the air. A large golden hand of more than ten sizes was shot out, first sweeping away the rebounded sword light, and then instantly hitting the yellow crystal wall.

But unexpectedly, the big golden hand actually hit the crystal wall this time, and then disappeared immediately.

"Successful!" Li Feiyu said excitedly with joy on his face.

But Lu Yuan looked stern, turned around suddenly, protected Doctor Mo and Dr. Mo behind him, and looked at a certain crystal wall.

But when he saw the crystal wall twisting, Lu Yuan's previously transformed big hand broke out of the wall. It looked several times stronger than before, and he went straight to Lu Yuan to shoot him.

"Sure enough!" Lu Yuan's eyes narrowed, golden scales appeared on his hand, and he shot forward.

After the explosion, a disintegrating spiritual storm swept through the space.

"My son!" A cry of grief and anger sounded from nowhere.

Only then did Lu Yuan realize that while he was just protecting Doctor Mo, he had forgotten about the evil flames.

They have now been blasted into two pools of bloody mud by the violent spiritual power.

"Lu, I want you to pay with your blood!" The roaring voice of the old devil fire echoed around.

"Then come out and kill me!" Lu Yuan smiled coldly.

"Do you think I will accept your provocation? Try the Qingyang Karma Fire that tens of thousands of my Demon Flame Sect's disciples jointly exert, and see how long you can last!"

"Qingyang Yehuo? Could it be more powerful than Qingyang Demonic Fire?" Lu Yuan's expression changed.

At this moment, he suddenly felt that the power on the surrounding yellow crystal walls was rapidly weakening, and it retreated by less than half in the blink of an eye.

"Go and see who has closed the formation!" The angry voice of the Demon Fire Old Monster sounded again.

Lu Yuan knew that Brother Tiezi had succeeded!

At this time, spiritual consciousness can already penetrate deep into the crystal wall.

Through perception, it can be confirmed that there is an early Yuanying in the formation, as well as twenty or thirty pill-forming monks. As for low-level disciples such as those in the foundation building stage, there are even more.

But just a few more breaths later, the momentum of the formation's weakening power stopped, and it remained so.

"Did something happen?" Lu Yuan's heart skipped a beat, but he didn't dare to delay.

Because he was worried about being attacked again, Lu Yuan instantly transformed into a six-foot-long golden body and slammed his fists at a certain crystal wall.

After an indiscriminate bombardment, although most of the power on the crystal wall was lost, it was still indestructible.

Even whenever Lu Yuan's fist hits the crystal wall, he will receive a tough rebound force, and as his strength increases, the rebound becomes more powerful. Lu Yuan, who now has a golden body, feels a little stinging.

This was after it was destroyed. If it was like the complete formation just now, Lu Yuan couldn't imagine how powerful it would be when it bounced back.

'Daoxuan returns for a while' is worthy of being one of the top ten prohibitions in ancient times!

Just when Lu Yuan was about to think of other ways, his eyes suddenly shrank and he suddenly left the crystal wall.

"What's wrong! How come you, a dignified Yuanying monk, are like a mouse meeting a cat?" Li Feiyu asked with some confusion as he had seen Lu Yuan display his power.

"So what if I am a Nascent Soul cultivator? Do I have no opponents?"

"Isn't it rumored that with your current magical power, no one can do anything about it except for late-stage Nascent Soul monks?"

"What if some late-stage cultivators really arrive!" Lu Yuan's face became extremely gloomy.
