After Lu Dong finished speaking, he ignored the captured demon commander and turned around and walked towards his headquarters.

"Put them in custody and wait for the lord of the city to send them down." Jiang Zhantian said to the soldiers around him.

However, no one noticed that there were some changes in the stone forest, and the demonic aura was even stronger. In the stone forest, you can barely see your fingers, and there is a floating demonic energy everywhere.

The sound of gold and iron colliding sounded, and slowly more and more gold and iron resonances sounded. It was dense, like the sound of countless blacksmiths striking iron at the same time. But the sound was so small that it wouldn't alarm the person asleep.

At this time, the bioradar does not show any red dots, and it seems that there is an energy affecting the bioradar. It can't scan the situation inside the stone forest, so it can't detect any changes in the stone forest.

As time slowly passed, the demonic qi had turned the entire stone forest into a world of demonic qi.

On the side of the legions of each race, after annihilating the demon scout troops, every warrior was a little weak. So they all fell asleep, unaware that great danger was approaching.

Lu Dong and the others are still studying the next attack of the demon clan at the command headquarters, but Lu Dong has been absent-minded.

A strong instinct of danger had been stimulating Lu Dong's brain, but Lu Dong couldn't see where the threat was coming from.

Lu Dong's gaze swept over everyone's faces, but he didn't find anything out of the ordinary.

The old survivor found that Lu Dong was absent-minded, so he walked over.

"What's wrong? Look at your absent-minded look. The old man then asked.

"I don't know why? I always felt like danger was about to happen, but I couldn't find the source of the danger. My instincts have always stimulated me and alerted me to danger. Lu Dong said to the old survivor.

"Oh! Could it be that the demons are moving again? The old man said suspiciously.

"I don't know, I'll send someone over to take a look!" Lu Dong continued.

"Come on, let's see what's going on on with the bioradar? There is a situation to report in a timely manner. Lu Dong said to a soldier outside the door.

The soldier answered, and quickly ran to the bioradar monitoring room. But there was nothing abnormal on the bioradar, and the soldier quickly reported back to Lu Dong.

"Something is wrong, the intuition is getting stronger. There must be some action from the demons, no! I'll have to send someone to observe it. Lu Dong said helplessly.

"I'll check it out! Even if there is danger, I can easily retreat. The old man continued.

"No, Elder Yang! You must sit here, lest the demons take advantage of it. Lu Dong continued.

"Don't worry, even if you are in danger, I will be able to come back in time." The old man said.

"That'...... All right! Be safe yourself. Lu Dong said helplessly.

The figure of the old man disappeared in an instant, appearing in the sky above the stone forest. With the naked eye, the entire stone forest was covered with demonic energy. I couldn't find anything at all, so I had no choice but to use my mental power to probe.

The old survivor exuded a powerful spiritual power, and slowly probed towards the demonic energy in the stone forest. Soon it encountered obstacles, and a transparent film blocked the spiritual power of the old and dead.

"Good guy, there's a problem. Since they also use formations to isolate their breath, they just don't know what they want to do? The old man thought with a frown.

"Forget it, whatever they want to do. Go back and inform them first so they can prepare. Thinking of this, the figure disappeared in an instant, appearing in the headquarters of all ethnic groups.

"How? Elder Yang, is there any situation? Lu Dong asked anxiously.

"That's right, the demons used a formation. Isolate all the energy breath, so that the bioradar can't detect the abnormality. The old man continued.

"And such a formation?" Lu Dong said with a frown.

"That's right, ancient myths and metaphysics are not groundless, they all have a certain basis." The old man said.

"Is there a way to find out what they're doing?" Jiang Zhantian then asked.

"There's no way except to break their formation. But then they will be alert immediately. The old man said helplessly.

"What then? Why don't we let them get something out there that we don't know about, and we'll be very passive. Jiang Zhantian continued.

"Calm down first, they are hiding people like this just to throw troops to Earth. We can wait and set up a more powerful killing array outside. Let them face the threat of killing as soon as they come out, which will also reduce our losses. The old man continued.

"It makes sense, the predecessors are worthy of being the god of war of the previous era." Lu Dong's eyes lit up and he said excitedly.

"But the resources needed to set up such a large killing array are very huge, can we supply them?" Jiang Zhantian said with a frown.

"If you can't supply it, you have to supply it, this is the last war. If we lose, it will be an extinction! The old man continued.

"Yes, then let's decide! I don't know what formation the seniors need to arrange? Jiang Zhantian said helplessly.

"What do you think?" The old man asked Lu Dong with a smile.

"I want to arrange the Twelve Heavenly Gods Great Array, even if the masters of the demon clan appear, we can destroy some of them." Lu Dong continued.

"The Twelve Heavenly Gods Great Array? However, we don't have twelve ancestral witch-level powerhouses, and it is difficult for them to lay out this formation. The old man continued.

"I can divide the Witch God Legion into twelve squads and work together to launch this big array." Lu Dong said with confidence.

"But in this way, the power is greatly reduced. When you meet a demon king-level powerhouse, you can instantly break your formation. The old man said.

"So you need to be in the formation, senior, if there is a strong person at the level of the demon king, appear. Just bother the seniors to help, as long as we hinder him, we can win a big victory. Lu Dong continued.

"Huh! This method is okay, I can block their demon king-level characters. Then you quickly kill those demon soldiers, and when you have your hands free, even the demon king will run away. The old man said softly.

"Okay, then let's arrange it like this! All the clans immediately mobilized the materials needed for the great array and sent them over as soon as possible. Lu Dong continued.

The commanders of each clan quickly ran towards their own tribes, and issued orders one by one. The entire legion of all ethnic groups turned rapidly, and truckloads of supplies and materials appeared on the frontline battlefield.

Lu Dong came to the Witch God Legion station, and the entire Witch God Legion was quietly gathered below.

"My warriors, your chance to make meritorious service has come. I'll give you a task later, it's not very difficult for you. That is, the Twelve Heavenly Gods Great Array, which has been allowing you to gather and train, will shine in this battle of extermination. Do you have faith? Lu Dong yelled at the Witch God Legion warriors below.

"The witch god does not die, and the spark does not die"

"The witch god does not die, and the spark does not die"

"The witch god does not die, and the spark does not die"

All the Legion warriors of the Witch God chanted this slogan feverishly, like the most sincere believers singing the praises of their gods.

"How did you do it, these warriors seem to have taken you as if they were their faith." The old man asked suspiciously.

"Actually, I didn't do it, but the witch god inheritance did it." Lu Dong said with a wry smile.

"It's kind of interesting, the Wu Clan shouldn't use the Inheritance Tower, right?" The old man continued.

"That's right, they came out of the Tower of Inheritance. So serve me wholeheartedly. Lu Dong continued.

"No wonder, it seems that the Wu Clan has invested a lot of money on you! They are very optimistic about you and hope you will not let them down. The old man continued.

"Don't worry! I will definitely put an end to this war, and I will never let them come back again. Lu Dong secretly made up his mind.

"Let's go! Once the mobilization is over, it is time to set up formations, and no one knows when they will come out. The old man said.

"Well, let's go!" Lu Dong continued.

Lu Dong followed the old man and turned to leave, and the captain of the Witch God Legion also followed with the Witch God Legion. Soon this force of 1,200 men came to the battlefield.

All the preparatory materials and materials were already waiting to be retrieved here, and Lu Dong instructed the team leaders to take the materials for the formation and disperse them in the designated location.

The twelve squads were divided into twelve directions, and they surrounded the isolation formation of the demons. Each warrior was preparing according to the formation method of the Twelve Heavenly Gods, and soon bursts of mist rose from the entire periphery of the stone forest.

Twelve pillars of light appear on the battlefield, after the pillars of light rise. Each pillar of light emits more pillars of light, and each pillar of light intersects tightly. Eventually, it all faded away, and the sky was as if nothing had happened.

With the passage of time, there have also been changes within the demon formation. A terrifying roar came out of the formation, from the occasional one at the beginning, to the last endless roar from inside.

Suddenly, the demon formation began to fade slowly, and burly figures appeared in everyone's eyes. Rows of huge demonic beasts appeared in front of the warriors of all races, and these demonic beasts were generally three meters tall. And there are demon soldiers sitting on their backs, and these demon soldiers are all very burly. He has a thick armor on his back and a dragon spear similar to the West in his hand.

"Beast cavalry? What the hell do the demons want to do? The old man said with a frown.

"This shape is very oppressive, and the soldiers of our various races should not have such a burly existence." Jiang Zhantian continued.

"They are the regular army of the demons?" Lu Dong asked with a frown.

"That's right, it's not just the regular legion, it's the elite of the regular legion." The old man said.

"Are they going to fight us to the death?" Lu Dong continued.

"I don't know, but the demons rarely dispatch this force. It should be that they want to fight us to the death or use it to defeat us. The old man said.
