The northern border of Central Plains.

The powerful gods of the human race gathered and stationed in the northern border to guard against the demon race's massive move southward.

In the past few days, apart from the soldiers from Mobei, the busiest people were the disciples of Confucianism.

Although the demon army has not yet reached the northern border, strengthening the entire northern border's defense line is not an easy task.

This is because there are not many natural defenses in the north, and relying solely on the cities built by humans is far from enough to resist the invasion of the demon army.

“It would be great if there was a Great Wall!” On the city wall, the elderly Lord Tan Tai looked at the busy Mobei soldiers and Confucian disciples and sighed softly.

According to the current defensive fortifications in the north, in order to stop the demon army, in places where natural barriers and city defenses are lacking, we can only rely on human lives.

"Five years ago, Instructor Li mentioned the construction of the Great Wall."

At the side, Lord Baidi said with a complicated expression, "But this is impossible for the Eight Tribes of Mobei."

Unlike the Central Plains dynasty, which was good at building cities and had abundant manpower and material resources, the Eight Tribes of Mobei were better at fighting on horseback and had almost no experience in building city defenses.

"Is there any news from the Great Shang Dynasty?" asked Lord Tan Tai.

"not yet."

Lord Baidi shook his head and replied, "The Central Plains court has always been notoriously slow in making decisions. The interests of all parties need to be balanced. Let's wait a little longer."

"We can wait, but the demons probably can't." Lord Tan Tai looked to the north and murmured softly.

As soon as the two men finished talking, suddenly, in the far north, which had been quiet for several days, thunder roared and the entire sky lit up.

"what happened?"

On the city wall, several powerful gods of the human race arrived in an instant, looking towards the north with shocked expressions on their faces.

"The calamity of the divine realm?"

The witch queen asked in surprise, "Didn't they say that when people or monsters transformed by gods step into the divine realm, they will not attract heavenly calamity?"

what's the situation.

“Perhaps, this demon king who has broken through the fifth realm has not been possessed by a god.”

Beside him, Xiao Yiren replied solemnly, "Instead, he entered the divine realm with his own strength."

"Mysterious Wind Demon Emperor!"

Not far away, Fa Ru was looking at the northern sky and said, "This aura must be from him."

"Amitabha, Brother Li."

In the darkness far away from everyone's sight, Sanzang sensed the fluctuations of breath coming from the north and said, "The Black Wind Demon King seems to have escaped."

Breaking through the fifth realm is not an easy task. If the Demon Emperor Xuanfeng is still imprisoned by the Demon Ancestor and his cultivation is restricted, it will be almost impossible for him to break through.

"Ah."

Inside the Five Realms Formation, Li Ziye nodded and said, "It should be Shui Jing's previous behavior that made the Demon Ancestor choose to release Xuan Feng."

"Brother Li, does this mean that Demon Ancestor trusts Shui Jing and the others more and more?"

Sanzang said excitedly, "This is really good news."

"Do not."

Li Ziye shook his head and replied, "It may not be good news."

"Not good news?"

Sanzang asked in surprise, "Why?"

"If you were the demon ancestor, and there was a possibility of recruiting a powerful fighter like Xuanfeng, would you have just ignored him?"

Li Ziye asked back, "Even if the Demon Ancestor knew that Xuanfeng and Shuijing were loyal to Qingqing, one thing would not change. No matter who is in power in the demon clan, nothing will change when the demon clan moves south, so..."

At this point, Li Ziye paused and said in a deep voice, "If I were the Demon Ancestor, I would definitely use Qingqing's life to make a deal with Xuanfeng and the others!"

After hearing the former's explanation, Sanzang was shocked and said, "Brother Li means that Xuanfeng, Shuijing and the others have joined forces with the Demon Ancestor. Aren't they afraid that the Demon Ancestor will go back on his word?"

"Of course I'm afraid."

Li Ziye replied, "The alliance between Xuanfeng, Shuijing and Yaozu is definitely not solid. It can even be said that they have their own agenda. However, there is no conflict between the two sides in their attitude towards the human race."

Upon hearing this, Sanzang looked towards the north and said, "Then what we are going to face next is an even more fierce attack from the demon tribe."

"Correct."

Li Ziye nodded and said, "From the beginning to the end, the relationship between the human race and the demon race has not changed. It's just that Qingqing is more inclined to fight for resources, while other powerful demons want to destroy the entire human race."

"Brother."

Just as the two were talking, Huanzhu's voice rang in Li Ziye's ears, reporting, "Please come back soon. Senior Nan Wang has made some progress."

"Which thing?" Li Ziye asked with a slightly serious expression after hearing Huanzhu's report.

"Mirror!" Huanzhu replied.

"I'll go back right away." Li Ziye responded, and without any delay, he immediately rushed towards the direction of the Shang capital.

"Amitabha, Brother Li." Seeing this, Sanzang was about to speak, but the person in front of him disappeared.

Not long after Li Ziye left, a strong wind blew in the north, and a terrifying wave of demons rushed out again, attacking the human world again.

Above the monster tide, the Demon Ancestor stood in the air. Behind him, Xuanfeng, Mingyuan, Shigui and other monster generals walked out from the extreme north one after another and rushed to the human world together.

The appearance of powerful demon clan members indicates that a full-scale war between the two clans has broken out!

However, at this moment, Li Ziye, who was supposed to help on the battlefield, returned to the capital of Dashang. His figure flashed past at a high speed, and soon he entered Li Garden and appeared in the East Courtyard.

"Brother."

In the East Courtyard, Huanzhu looked at her brother who appeared out of thin air in front of her, walked up quickly, and said, "Senior Nan Wang, I'm waiting for you."

"Let's go together." Li Ziye said, and walked quickly towards the laboratory in front.

In the largest laboratory in the East Courtyard, Mao Nanfeng stood in front of the experimental table, where the Ghost Killer Girl lay very cooperatively, quietly and well-behaved.

Li Ziye walked into the laboratory, looked at the Nan Wang in front of him, and called out, "Senior Nan Wang."

In front of the experimental table, Mao Nanfeng turned around and said lightly, "You are back as expected."

"Don't talk about me for now."

Li Ziye stepped forward and asked, "Have you figured out the principle of the reflective mirror?"

"That's not true."

Mao Nanfeng replied, "However, based on Chang Yu's theory of the Soul Transformation Device, I discovered that if I use dragon energy to infuse it, it can, to some extent, amplify the mirror power in the Ghost Killer Woman's body."

"Magnify the power of the mirror?"

When Li Ziye heard the news, his expression suddenly froze and he asked, "What's the intensity?"

"It should be able to withstand a divine level spiritual consciousness entering and exiting once." Mao Nanfeng said seriously.

"Time." Li Ziye continued to ask.

"About twenty-four hours."

Mao Nanfeng replied, "It is much more difficult to open the reflector than to maintain it. Therefore, once the reflector is opened, it cannot be closed until the reflector power in the Ghost Killer is completely exhausted."

"What I mean is that I have a chance to go to the Kingdom of God for twenty-four hours, right!" Li Ziye said.

"Correct."

Mao Nanfeng responded affirmatively, "Haven't you been looking for a way to separate the soul? Now, as long as you find Chang Xi, maybe you can get what you want."
