An image appeared in front of Li Yuanqing. The image gradually became clear, as if he was there.

In the image was the back of a man. He stood at the top of the mountains, facing a huge black dragon. The black dragon’s eyes were like two scorching suns, emitting terrifying flames. The man was in front of it, as if he was close, but fearless.

Suddenly, the two sides that were originally motionless suddenly attacked each other. Two huge balls of energy gathered between the two sides and exploded. The high temperature produced by the explosion emitted a scorching flame, like a scorching sun. This incomparably huge sun exploded with a bang, emitting countless energy aftershocks in all directions, turning the surrounding mountains into ashes.

The originally lush and green trees on those mountains instantly dissipated under the destruction of this energy. The entire mountain range lost all life and turned into charcoal-like land.

The image flashed past with a strong and blinding light. After that, it was after the battle. In the ruins, the man slowly stood up, but the black dragon was nowhere to be seen.

After that, the scene changed. It seemed to have arrived at another human city. At this moment, this man was extremely glorious. In the face of the respect of thousands of people, he was already the City Lord.

Every casual call, and every move he made was responded to by countless people.

At this moment, the man had clearly reached the peak of his life. He was so glorious. Everything was so dazzling. This was the glory that the human race had once obtained. This incomparably bright city was a powerful fortress built by the human race.

Just looking at this scene made Li Yuanqing feel overwhelmed, as if he was deeply affected by the scene.

However, the good times did not last long. Li Yuanqing had only watched for a while when the scene changed. The entire human city seemed to have fallen into winter. This place was so desolate and dark. Everyone had lost their vitality. Everyone was wandering around like a zombie.

Then, in the sky of the city, a huge dragon head suddenly appeared and suppressed them. At this moment, the human race had lost all their fighting spirit. They had completely forgotten how their ancestors had once resisted powerful enemies.

The outcome was obvious. When the scene changed again, the human city had already disappeared.

The huge city that was originally built here disappeared in the blink of an eye, leaving only a large desolate empty space. However, these clear traces showed that humans had once lived in this city.

Li Yuanqing did not know why the man in front of him wanted him to see these things. He had never heard of these strange scenes before. When he arrived here, the humans here had already rotted into the soil. They were completely defenseless against a powerful enemy.

He did not expect that there would be such a glorious period in the past. It was unknown what the ancestors of the human race would think when they saw this.

Later on, this scene became even more oppressive, as if there was a dark cloud pressing down on his head. The dark cloud was as heavy as a thick fog and could not be dispersed no matter what, making it difficult for him to breathe.

Until the scene in front of him became darker and narrower. Finally, it shrank into this narrow cave, as if this place had become the home of everything.

When Li Yuanqing returned to reality, he looked up and saw the last scene he saw inside. Therefore, he actually felt a very familiar feeling. This hall was so ancient that it had been sealed for thousands of years. Today, it was opened and seen again.

Li Yuanqing did not understand why he would show him such a strange scene. If the fellow in front of him was really the Blood Vine, how was Li Yuanqing going to face him? This person was so powerful that he could vaguely suppress his contract. This way, even if he wanted to escape, he could not do anything to him. However, this fellow’s actions were really puzzling. No one knew what he wanted to do.

Li Yuanqing looked at the man in confusion, but the man did not look like he was about to speak. He just sat there in a daze, as if he was thinking about something.

“So, are you really the Blood Vine?” Li Yuanqing carefully sized up the man and asked, “I know I might have asked you to do some things in the past, but I thought that we did it under the circumstances that both sides acknowledged each other, so…”

Li Yuanqing looked at the fellow in front of him and was not confident. This person emitted a powerful force from head to toe. It was clearly impossible to go against him. With this guy’s strength, he probably could not do anything to him. Although Li Yuanqing did not know why things had turned out like this, he could only accept his bad luck.

The Blood Vine was a very capable subordinate. Li Yuanqing still felt a little regretful that he suddenly lost a capable subordinate.

Just as Li Yuanqing was muttering in his heart, the man suddenly said, “It failed.”

Li Yuanqing’s gaze was attracted back. He was already thinking of an excuse to escape just now. Now that this person had suddenly spoken, there seemed to be no need to escape.

“Failed? What failed?”

“Everything has failed.”

The man suddenly raised his hand. His hand was very dry and had no color at all. But this was all normal. If this body had really been sealed here for thousands of years, it would be good enough if he still looked human.

“I have no grudges with you, Senior. If you have any plans, I will definitely not stop you!” Li Yuanqing hurriedly distanced himself. “If I hadn’t made an agreement with you previously, I definitely wouldn’t have come to this place. What you want to do is your business. I won’t interfere. Don’t worry!”

This person was mumbling and didn’t look too clear-headed. If he took things too hard and did something, he would die here today.

As he spoke, he suddenly seemed to have reacted. He suddenly looked up at Li Yuanqing and said, “Kid, no matter what, I still have to thank you. Without your help, I wouldn’t have been able to get here.”

“Senior, don’t say that. It was nothing.”

“I don’t have much time left. There are some things I have to tell you.”

Li Yuanqing was stunned by his words. He could not take it anymore. Just now, he was still worried that this fellow would suddenly go crazy and treat him as an opponent. Now, he’s pretending to trust him, as if there was something very important that he could not miss.

“Senior, are you sure you didn’t misjudge me?”

Li Yuanqing only wanted to leave this place quickly. He had no grudges with this fellow in the past and had never had any grudges with him recently. Today, he had suddenly become the person he was entrusted to. It was too sudden.

At this moment, a voice suddenly sounded in his mind.

[Signed in successfully at Heroic Spirit Hall! Reward received!]

[Reward One: Secret Mechanism Technique!]

[Reward Two: Five hundred years of cultivation!]

At this critical moment, the reward for signing in suddenly appeared. Li Yuanqing was so frightened that he broke out in a cold sweat. However, after calming down, he immediately chose the five hundred years of cultivation reward.

“I’ll choose five hundred years of cultivation!”

[Reward issued!]

Li Yuanqing, who was sitting at the table and chatting with the man, suddenly felt his eyes turn listless. A thick barrier appeared around his body.

In the thick yellow barrier, Li Yuanqing’s aura soared steadily. In a short while, it reached an extreme. His body kept emitting hot white fog, as if it was steaming the sweat in his body. The water became thicker and thicker, gradually filling the entire shield.

Li Yuanqing’s figure gradually disappeared from the white shield that was more than two meters in diameter. It was as if Li Yuanqing had disappeared inside.

The mysterious man sitting opposite Li Yuanqing did not disturb him. Instead, he was very surprised to see Li Yuanqing like this. He wanted to help, but after feeling the energy in Li Yuanqing’s body continuously gathering, he was relieved.

It was as if everything that happened in Li Yuanqing’s body was what he wanted to see.

After an hour, the fog around Li Yuanqing slowly dissipated. He sat on the stool and completed this advancement. When he opened his eyes again, he had already become a sixth-grade Formation Realm expert.

He had advanced by three grades. These five hundred years of cultivation made Li Yuanqing feel refreshed and full.

When he faced the man in front of him, he felt even more confident. In the situation just now, he had no confidence in talking to the man at all. However, this sudden sign-in had instantly improved him greatly.

The man looked at Li Yuanqing in disbelief. His brows seemed to be filled with confusion, but after looking at him for so long, he gradually felt relieved.

“Senior, please forgive me. It’s just that this is my secret. I don’t want others to know.”

The man slowly nodded and looked at Li Yuanqing. “I know this is your secret. I won’t tell anyone, and I have no way to tell anyone. I’ll stay here forever and can’t get out. I’m afraid this is the last time I’ll appear in this world. There would never be a person named Teng Wudao.”

Li Yuanqing was a little confused by the man’s words. He hurriedly looked at the man and asked, “Senior, what do you mean? I see that you’re energetic and strong. With your strength, you can dominate the world after you go out and live for hundreds of years. Why do you say that you don’t have much time left?”

After obtaining his strength, Li Yuanqing became more confident. He looked around carefully. Why didn’t the system trigger the signing in mechanism when he entered this place called the Heroic Spirit Hall? Instead, it triggered the signing mechanism after he saw that scene.

Li Yuanqing did not know the logic of the system. He could not figure it out no matter what. This system always popped up at strange times. He was already used to it.

The man reached out and touched his chest. Suddenly, he touched a hard object that protruded. He seemed to be relieved. He slowly reached into his clothes and took out a golden key.

It was not particularly accurate to call it a key. This thing looked very strange. There were no lock patterns on the key at all. It was just a circular piece with a small cylinder connected to it. It looked ordinary, as if there was nothing special about it.

However, the material used to make this key attracted Li Yuanqing’s attention. This material emitted a powerful suction force for no reason, as if it was some precious material.

The man touched the key in his hand and took off the rope hanging behind him. He handed the key to Li Yuanqing.

Li Yuanqing looked at the man in confusion, not understanding why he did this. “Senior, what is this?”

The man took a few deep breaths and looked up at Li Yuanqing again. However, his face was no longer as lustrous as before. Instead, it gradually became blurry.

“This is the key to open the treasure vault. There are still the last assets left behind by the human race there. If the human race wants to rise again, we must find the most important assets!”

The man said this very quickly, and Li Yuanqing did not understand for a moment. He hesitated for a moment before taking the key. He turned to the man and said, “Senior, if it’s not convenient for you to leave and you want me to pass it on, I will definitely do my best. I will pass this to the current Saintess of the human race.”

When the man heard his words, he suddenly pressed down his hand and looked at Li Yuanqing very solemnly. “You will definitely be able to lead the human race to repeat its past glory!”

“Senior, you might have misunderstood. To be honest, I’m not from the Catacombs to begin with. I just happened to come here. Senior, I’m afraid I’ll disappoint you if you entrust such a precious thing to me.”

Li Yuanqing still wanted to push the key back, but this man did not give him any room to refuse.

Li Yuanqing had just taken action when the man in front of him was pushed into a sandstorm like a pile of dry powder.

A person who was originally alive completely disappeared amidst the pushing. Such a powerful senior was gone just like that.

Li Yuanqing was shocked. He stood up and looked around, but there was no one around. The small room was originally empty, and now it had returned to its original dim state.

“Senior, what are you doing?”
