Having many children brings many blessings; the struggle for power begins with marriage.

Upon hearing Bai Qingqing's words, Lu Chen immediately stood up from his desk and muttered to himself, "Finally, we can set up the formation."

Although the Seven Killings Formation for Protecting the Meridians has a good defensive effect, it requires a lot of materials. Lu Chen was initially worried that he wouldn't be able to gather enough materials, but he didn't expect to find the materials needed to build the formation so quickly.

Come to think of it, if this world didn't have the materials needed to build the Seven Killings Protective Formation, the system wouldn't have given this formation to me as a reward.

Lu Chen walked from the desk to the main hall, then to Bai Qingqing's side, and put his arm around her waist, who was clad in white armor, saying, "Take me there."

Bai Qingqing said expressionlessly, "Your Majesty, please follow me."

Bai Qingqing then led Lu Chen to Fengyun Palace.

The materials for constructing the Seven Killings Protective Formation were quite valuable, so Bai Qingqing had them delivered directly to Fengyun Palace to avoid any problems that might arise.

As soon as Lu Chen entered Fengyun Palace, he saw his wives and concubines gathered around a pile of things, discussing their uses.

Upon seeing Lu Chen arrive, the women quickly made way for him. Chu Yuqin asked curiously, "Your Majesty, what are these things for?"

On the ground were some seemingly useless things: tree trunks, leaves, animal bones, and several buckets of blood from some unknown creature.

At this moment, Lu Chen said, "These things are for setting up formations. With formations, even experts at the Celestial Realm will not be able to cause trouble in Yan City."

Upon hearing this, the women were first taken aback, then overjoyed.

Especially Mu Zixuan, Da Zhou, and Xiao Zhou, whose cultivation levels were the lowest, always had to be accompanied by strong people when they left the palace, and they were also very afraid to go out.

After all, Lu Chen has too many enemies. No one knows how many spies and agents are in Yancheng. These people may capture them and use them to threaten Lu Chen.

For them, Yancheng is now more dangerous than before.

If the array they set up can protect them indefinitely, then they will be able to move around freely in Yan City from now on.

Although the palace was large, it was still much smaller than Yancheng. They would get tired of staying in the palace all the time.

After regaining her senses, Mu Zixuan quickly asked, "Your Majesty, can this formation protect us at all times?"

Although Lu Chen said that even celestial beings wouldn't dare to cause trouble in Yancheng, Mu Zixuan didn't believe that the formation could necessarily protect their safety.

What if this formation is a passive defense, only effective when activated? By the time something happens to them, the formation might not even have time to activate.

Lu Chen instantly understood what Mu Zixuan wanted to ask, and he said directly, "This formation can be activated at any time. It can be activated by any of my wives, concubines, and children. However, this formation cannot harm my wives, concubines, or children."

"If you go out in the future, as long as you are still in Yancheng, you can also mobilize the power of this formation."

"However, the spiritual energy in this world is very thin. Although this formation can absorb the surrounding spiritual energy, it cannot be activated for a long time."

"Therefore, it is best not to activate the killing formation unless absolutely necessary."

The Seven Killing Formation for Protecting the Meridians is divided into two parts: one part is an actively activated killing formation, and the other part is a passive defense.

The passive defense mechanism is always in operation. As long as a powerful enemy approaches, the Seven Killings Array can detect the killing intent and keep the enemy at bay.

The active killing formation means that when an enemy enters the formation, Lu Chen's wives, concubines, and children can actively activate the killing formation to kill the enemy. However, activating the killing formation will consume a large amount of spiritual energy.

At this moment, Lu Chen arrived in front of the pile of array materials and prepared to set up the array. However, just then, the system notification sounded.

[The host's cultivation level has not yet reached the Celestial Realm. With the host's current spiritual power, it is impossible to set up the entire Seven Killings Protective Formation.]

Upon hearing this notification sound, Lu Chen was immediately stunned.

What?

Unable to set up?

Why would the system reward him with this formation?

Lu Chen quickly realized that although he couldn't make the arrangements himself, he had celestial beings under his command, and he could have them make the arrangements.

Just as Lu Chen was thinking this, the system notification sounded again.

[The host can have a celestial being transfer spiritual energy to them, thus allowing the host to complete the setup of the Seven Killings Protective Array.]

Seeing that the system had said so, Lu Chen did not hesitate and said directly to Bai Qingqing, "Xiao Bai, have someone call Xia Tianyuan and Mu Hongguang here."

"Yes, Your Majesty."

Bai Qingqing then left Fengyun Palace.

After Bai Qingqing left, Lu Chen didn't rest. He began to seriously consider how to set up the formation.

Not long after, Bai Qingqing appeared at Fengyun Palace with Xia Tianyuan and Mu Hongguang.

Fengyun Palace is Lu Chen's harem. Apart from Lu Chen's offspring, no men are allowed in the harem, so Xia Tianyuan and Mu Hongguang always felt a little uncomfortable.

Lu Chen had no choice; he needed to set up the array core in Fengyun Palace, so he could only send Xia Tianyuan and Mu Hongguang here.

Moreover, they were only setting up a formation, and the two of them wouldn't stay in the harem for too long, so Lu Chen didn't care too much.

Lu Chen then said to Xia Tianyuan and Mu Hongguang, "Sect Master Xia, Palace Master Mu, I am going to set up an array here. You two should transfer your spiritual energy to me to ensure that my spiritual energy is sufficient."

Upon hearing this, the two quickly replied, "Yes, Your Majesty."

Lu Chen then began to circulate his spiritual energy, and the next moment, all the materials used to set up the array on the ground floated up.

Immediately afterwards, a formation pattern appeared in Lu Chen's mind. Lu Chen channeled his spiritual energy into the formation pattern, and the materials floating in the air began to mix.

After the materials were mixed together, they turned into a black liquid, which then gathered above Lu Chen's head, forming an array pattern.

However, at this moment, Lu Chen's spiritual energy was clearly not keeping up. Seeing this, Mu Hongguang and Xia Tianyuan quickly stepped in and transferred their spiritual energy to Lu Chen.

Lu Chen instantly felt his spiritual energy become incredibly abundant again, and he continued to set up the formation.

Once everything was ready, the black array pattern above Lu Chen's head rapidly rose and grew larger and larger.

Soon the pattern covered the entire city of Yan, and the people of Yan were stunned by what they saw.

Once Lu Chen felt it was about time, he immediately ordered the formation to descend. The formation diagram in the sky fell instantly, startling the people of Yancheng. Some people were already preparing to flee, but the formation diagram fell very quickly, and before they could hide, it had already landed on the ground.

Seeing that the formation posed no threat to the people, the residents of Yancheng finally breathed a sigh of relief.

The next moment, Lu Chen activated the formation. The patterns on the formation gradually changed from black to gold and emitted a golden light. This golden light quickly gathered into a semi-circle, enveloping the entire Yan City.

Seeing this, Lu Chen couldn't help but think, "Is this the Seven Killings Formation for Protecting the Meridians?" Unfortunately, there were no enemies around, so he couldn't test the formation's effects.

Lu Chen didn't think much of it. He then waved his hand, and the golden protective shield above Yan City disappeared. (End of Chapter)
