The passage extended to an unknown place, and Lu Chengchuan walked slowly in.

He didn't know what was ahead, nor did he know if there was a trap under his feet, so he took every step very carefully.

After walking for an unknown amount of time, he finally saw the exit in front of him. Lu Chengchuan was not anxious and continued to walk forward slowly.

Along the way, he found no danger in the passage.

As he approached the exit of the passage, he seemed to hear a heartbeat coming from inside. The heartbeat sounded steady and orderly, one after another. Unconsciously, Lu Chengchuan's heartbeat frequency matched the heartbeat inside.

It took Lu Chengchuan a while to realize this, which made him even more hesitant.

When he reached the exit of the passage, Lu Chengchuan hesitated for a moment. Feeling the outside world and his own heartbeat, he still stepped slowly inside.

The moment he stepped into the exit, he came to a wide space.

In the vast underground space, he saw the huge heart in the middle at a glance.

A huge scarlet heart, four or five meters high, requiring two people to hug it. There are several thick veins at the base of the heart supporting it.

The veins lead to the depths of the earth, and every time the heart beats, it draws a bit of strength from the depths of the earth.

The huge heart was beating, and Lu Chengchuan felt a great temptation, like a person who had been thirsty for two days encountering a spring of sweet water. Instinct drove him to move forward quickly.

He suppressed his instincts and stood there, looking at his heart carefully.

"Don't be...scared. Come here."

Just as he hesitated, a weak voice suddenly appeared in his mind.

As the sound rang out, a picture flooded into his mind.

In an endless dark space, a giant heart was traveling inside with a blue crystal. After an unknown amount of time, he saw a familiar planet, Earth.

The huge heart rushed into the earth like a meteorite and fell into the sea, while the blue crystal flew to a continent and to Guangnan Province of Shenghua Kingdom.

Soon, Lu Chengchuan saw himself lying on a hospital bed, looking extremely weak and as if he didn't have much time left.

Just as he was talking to his mother, a blue crystal traveled through countless spaces and landed on him.

The scene ended here, and Lu Chengchuan regained consciousness. He looked at the huge heart in the dark space, opened his mouth but said nothing.

This is when I obtained the system. What happened? What exactly was the scene just now?

"Don't be afraid, Lu Chengchuan, I've been waiting for a long time... and finally I've waited for you."

The mysterious voice was still speaking, and he actually knew that the person coming was Lu Chengchuan, which made the person even more nervous.

Lu Chengchuan slowly picked up the Beast King Sword and pointed the tip of the sword at the huge heart: "Are you a monster? Or something? Why do you know my name?"

"Just a dying man."

"Human? I can't tell you're human."

If this thing could be considered a human, there would probably be no monsters in the world.

"I know you have a lot of questions, and I know you don't believe me. It's okay, I'll explain it all to you."

The mysterious 'man' paused for a moment, and then a weak voice sounded again.

"I come from another world, and what you have is what I brought with me."

The weak voice revealed a shocking secret, which made Lu Chengchuan's face change suddenly. This heart not only knew his name, but also knew what was on his body.

"What is it?" Lu Chengchuan asked back. He was afraid that the other party was trying to trick him.

"Don't doubt the things that make you stronger. I brought them here, and I sent them here. Even though I can't use them, I know they're not simple."

"In just such a short time, you've become so powerful. You're truly not an ordinary being..."

A weak voice spoke to itself.

Lu Chengchuan fell silent. The other party really knew about his life-saving system.

"Who are you? Why did you become like this? Did you create that thing?"

"I told you I'm from another world. As for why I became like this, I chose to do so. And that thing, I don't have the ability to create such a magical object.

It chose you, I just sent it to you..."

"Why are you giving this to me?"

"It chose you, and I also want to ask your help with something, so I give it to you." said the weak voice.

"It's fused with your body, but not completely. As long as you agree to help, I can help you complete the final step of the fusion. Only then will you be able to fully control it."

"You didn't lie to me?" Lu Chengchuan was a little unconvinced.

But he felt that what his heart said was correct, but he didn't dare to believe his heart, in case his heart was holding back something bad.

"What do you want my help with? How are you going to help me fuse?"

After hesitating for a while, Lu Chengchuan asked.

"I ask you to save my world. It's about to fall. I want you to save the humans in that world. If you agree, I will use the last of my strength to help you completely merge with the divine object."

"Save your world? What makes you think I can save a world?"

Lu Chengchuan thought the heart was joking. He had already said he would save the world. He did have some strength now, but he felt that the heart would not be weaker than him. In the previous scene, it was carrying the blue crystal and moving through the mysterious space. He didn't know how it did it.

If his heart couldn't save his own world, how could he do it?

"Because you have that thing in you, it can help you. As long as you don't die, you will surpass me sooner or later." Xin's tone was weak, but full of confidence.

It spent countless hours researching this artifact, but gained nothing. In the end, Crystal chose Lu Chengchuan, and Lu Chengchuan did not disappoint it.

"I'm not as powerful as you think. I'm also a Saint, just like you... I only came to this world with the help of external forces."

Only a few decades had passed, and Lu Chengchuan had transformed from an ordinary, terminally ill man into a powerful saint. In the past, he simply would not have believed it.

"How are you going to help me fuse the divine object?"

"Come into the heart, I will send you to my world. When you go there, I will help you integrate. By the time you arrive, you will be almost completely integrated." The heart said slowly.

When Lu Chengchuan heard that they were going to use this method to help him, his face changed: "Why should I trust you? Will entering the heart help me or harm me? I may not know then."

This doesn't sound like a proper method. What if the heart wants to take over his body? If he goes in foolishly, he will be walking into a trap.

"I won't hurt you."

I promised him with a weak heart, but Lu Chengchuan still shook his head

"Again, why should I believe you?"

He saw the origin of the system, but he really couldn't believe what the heart said.

The heart was silent for a moment, then slowly spoke: "You are also a master in the soul realm. You should know that it is almost impossible for me to possess your body."
