After more than ten years on the mountain, you will become invincible when you come down.

"Niu Gen, don't worry about me. Just stay outside and don't let anyone in. I'll be fine..." Lu Feng said.

At this time, Lu Feng just needs to ensure his own safety. If someone comes to assassinate him at this time, he may not be able to deal with it, and it is easy for an accident to happen...

"But... I hear you are in such pain, are you really okay?" Niu Gen asked eagerly.

"It's okay...I have my own sense of discretion..." Lu Feng said.

Seeing Lu Feng's determination, Niu Gen was still worried, but Lu Feng didn't let him in. He would never go in...

As for Lu Feng, he had already experienced it for the first time. Although the pain was not relieved this time, Lu Feng at least knew what was going on and had a certain understanding in his heart...

So this time, Lu Feng focused all his energy on absorbing spiritual energy...

Lu Feng knew that this was an excellent opportunity. The spiritual energy from the outside world and the feedback after the fusion of the human emperor's bones could improve his realm...

This is definitely an excellent opportunity for Lu Feng, who has a very difficult time improving his realm in the secular world...

Therefore, Lu Feng could not let go of this opportunity. The more strength he could improve, the better...

From morning, to noon, until dusk, the sun gradually sets...

Lu Feng's realm also went from the early stage of the Golden Core, to the middle stage of the Golden Core, to the late stage of the Golden Core, to the peak of the Golden Core, and finally stopped at the early stage of Nascent Soul...

The golden elixir that was originally brilliant in the body has now turned into a human-shaped Nascent Soul...

Lu Feng clenched his fists, and the joints of his fingers made crackling sounds. Lu Feng felt that his whole body was full of strength at this moment...

Lu Feng punched a huge boulder in the cave.

"boom……"

This huge stone suddenly fell into pieces. The huge stone turned into small gravel in an instant. Even the cave shook, and the surrounding gravel fell one after another...

"Lu Feng, come out quickly, come out quickly, there's an earthquake!"

Niu Gen shouted as he rushed into the cave, trying to pull Lu Feng out of the cave...

When Niu Gen entered the cave, he saw Lu Feng still looking at his fist.

"Lu Feng, hurry up and leave. There's an earthquake. This cave is going to collapse later!" Niu Gen excitedly pulled Lu Feng over and was about to run outside.

Unexpectedly, Lu Feng still stood motionless and said calmly, "There was no earthquake. The movement just now was just caused by my punch. Will it stop now?"

"There was no earthquake...what? Did you punch it just now?" Niu Gen asked in shock.

Lu Feng pointed to the small gravel on the ground and said, "Look, the big stone that was here is now here..."

Niu Gen's eyes widened in surprise. He often came to this cave. There used to be a huge stone here, but now he scanned the entire cave and found that the big stone was indeed missing...

"Lu Feng, are you still a human? How did you do such a big stone?" Niu Gen asked in shock.

"no……"

"Ah? Are you a monster?" Niu Gen quickly made fighting moves.

It was as if Lu Feng was really a monster and he wanted to kill it.

"I said I'm not a human being, but a god. Do you believe it?" Lu Feng asked.

Niu Gen shook his head, then nodded, then shook his head again...

"Do you believe it or not? You are shaking your head and nodding..." Lu Feng asked.

"I believe you are not a human being, but I don't believe you are a god, because a normal person cannot break a big rock with one punch, and this rock is not made of tofu..." Niu Gen said.

Lu Feng's face was full of dark lines. Although he was indeed not a god, there was nothing wrong with him if he didn't believe it.

But why do we have to believe that we are not human? How do you look less human?

"Niu Gen, there are still many things in this world that you cannot understand. I can only tell you that I am definitely a human being. The reason why I can break this big rock is because I have practiced..." Lu Feng said.

"Cultivation? What is cultivation?" Niu Gen asked in confusion.

"Cultivation... practice means being able to blow up this big rock with one punch. Do you want to learn?" Lu Feng asked.

"Is it so powerful? If it is so powerful, wouldn't it be possible for me to move two more bricks at a time when I go to the construction site?" Niu Gen asked.

Lu Feng's face is full of dark lines. Emotions teach you to cultivate immortality, are they used to move bricks?

If you want to put it this way, you don't even need the elevator. The speed is so slow. Wouldn't it be faster and better if you just carry it and fly up?

"Niu Gen, you have chosen to practice, why are you moving bricks?" Lu Feng asked in confusion.

"The foreman said that if I don't go back to work, the previous wages will not be paid to me. I still have to go back to work, otherwise what will I eat?" Niu Gen said.

"In this way, if you follow me from now on, I will pay you a salary. The annual salary is 10 million. Is it enough for you? You don't have to move bricks..." Lu Feng said.

It's not that Lu Feng can't give him more, but he's afraid that too much money will make Niu Gen feel suddenly rich and he won't be able to get used to it, so it's better to let him get rich first and get used to it...

"That won't work. I moved those wages out brick by brick. I still have to go. When I get my wages back, I will practice with you..." Niu Gen said.

"You are such a fool. When you return to Yanjing, I will give you back your wages. Please stop going out recently and take good care of your mother. I will take you away when I come here next time..." Lu Feng said.

"Lu Feng, where are you going? When will you come back?" Niu Gen asked.

I came to Xiling because I have something to do. I will take you away after I finish my work in Xiling.

"Okay, I'll wait for you at home, waiting for you to come back..." Niu Gen said.

"Niu Gen, I will teach you how to practice first. I hope that by the time I come back, you will have accomplished something..." Lu Feng said calmly.

Lu Feng raised his eyebrows towards Niu Gen, and all the knowledge of cultivation was transferred to Niu Gen's mind.

Furthermore, a piece of Star Art was passed on to Niu Gen.

The reason why it is different from other people is because Wutian said that for a simple and simple person like Niu Gen, it is more suitable to practice the Star Art...

So Wutian also acted generously and passed down the Star Secret without Lu Feng saying anything...

Only such clean and pure people are suitable for practicing the Star Art, and can use the power of the stars to practice...

But not everyone can borrow it. If the most evil person practices it, I'm afraid he won't be able to borrow the power of a star. In that case, no matter how powerful the technique is, it will be useless...
