I traveled through time and space and became a demon. I want to be a demon god.

As the spiritual energy within the Lingxiao Treasure Vault grew increasingly dense, in less than the time it takes to drink half a cup of tea, the entire vault seemed to be filled with clouds and mist.

Xu Zhenfeng also had to use his demonic magic to see the scene inside the treasure vault.

He glanced around again, surveying the treasure vault. He saw that many of the treasures that had fallen to the ground had been returned to their original positions.

Some of the display cases were also restored to their original state, and the treasures that were originally inside began to be put back in their places.

Every now and then, the loose beams that had fallen to the ground would rise into the air and fly towards the top of the treasure vault.

The Lingxiao Treasure Vault did indeed begin to recover under the nourishment of abundant spiritual energy.

As they watched the humans and demons, the great cultivators of the Underworld were all working hard to maintain the Spirit Gathering Array, which was drawing in spiritual energy from heaven and earth.

Xu Zhenfeng suddenly felt a sense of unease.

For some reason, his unease grew stronger as the Lingxiao Treasure Vault visibly repaired itself.

As his gaze swept over the Demon King, he saw that the dense spiritual energy in the spirit-gathering array set up by the Demon King was almost liquefied. Suddenly, a flash of inspiration struck him. What did he think of?

"Get out! We can't stay here any longer! Everyone, get out of here right now!"

Xu Zhenfeng suddenly grabbed Lang Wumiao, who was sitting cross-legged beside him, and then flew towards the Demon King, still shouting incessantly.

"Everyone, get out of here immediately, don't stay in the treasure vault."

His voice was loud and clear, instantly spreading throughout the entire Lingxiao Treasure Vault. However, the humans and the great cultivators from the Underworld who were struggling to maintain the Spirit Gathering Array only glanced at him, but did not move.

Although several powerful demons of the Heavenly Rank paid attention to Xu Zhenfeng, they did not make a move.

Only the Demon King was grabbed by the arm by Xu Zhenfeng, and was about to question Xu Zhenfeng about what was going on.

At this moment, a very slight creaking sound came from the main entrance of the Lingxiao Treasure Vault.

The sound was like a bolt from the blue to Xu Zhenfeng, who had been watching the commotion at the gate.

"Hurry, the treasure vault doors are about to close."

As he uttered these words, Yama's voice also came through.

"Impossible. The Lingxiao Treasure Vault cannot be opened or closed by anyone except the King of Hell."

Xu Zhenfeng had no time to explain. Seeing that he couldn't pull the Demon King away, he dragged Lang Wumiao toward the gate without looking back, shouting, "Son, get out of here!"

Huangjingwa's voice immediately came from the front door.

"Dad, our Solomon's Seal has emerged."

Huangjing Doll was the most obedient to his father. As soon as he heard Xu Zhenfeng shout the first "Get out," the little guy had already dashed out of the Lingxiao Treasure Vault.

Lang Wumiao had no idea what his son had discovered. Was there some misunderstanding?

However, she still chose to believe her son immediately. When Xu Zhenfeng couldn't pull the demon king away, she didn't hesitate to kick the demon king hard.

Her kick sent the unsuspecting demon king flying out of his own spirit-gathering array and landing him near the entrance to the Lingxiao Treasure Vault.

After hearing Huang Jing Doll's voice, she grabbed Xu Zhenfeng and, in a flash, brought him to the entrance of the treasure vault.

Just as the mother and son demons were about to step out of the Lingxiao Treasure Vault, the door of the Lingxiao Treasure Vault was already closed, leaving only a narrow crack.

At this moment, the Demon King also realized something was wrong. In the nick of time, he roared and transformed into a dragon with greater strength and physical resilience, wedging the tip of his tail into the gap in the door.

Lang Wumiao seized the moment, grabbed Xu Zhenfeng, and rushed out the door. Just as her head was about to hit the crack in the door, her whole body became thinner, and then Xu Zhenfeng's figure also became as thin as paper.

Just as the last crack was about to close, the two demons floated out of the gate of the Lingxiao Treasure Vault.

The Demon King's roar had now turned into a muffled groan of extreme pain. The door to the Lingxiao Treasure Vault was still closing, and although it was briefly obstructed by his dragon body and tail, it was only for a blink of an eye.

Just as Lang Wumiao was pulling Xu Zhenfeng out of the treasure vault, the Demon King's tail was snapped off by the closing door.

Thus, the Demon King, along with the other great cultivators from the human underworld, was imprisoned in the Lingxiao Treasure Vault.
