With the message of this passage reverberated in his mind, Lin Mu immediately understood why he suddenly had the ability to devour vitality.

The North Sea represented infinite size and depth. If the cultivation reached an extreme state, it was just like the North Sea and could even accommodate the infinite Kun Peng.

What Lin Mu absorbed now was the vitality of life and it was still in its initial state. When he reached the later stage, it could collect the breath of heaven, earth, and the universe and absorb the essence of the sun and the moon. This was like the North Sea, which could contain both heaven, earth, and the universe.

Shock!

What a shock!

This cultivation method was completely beyond the imagination of Lin Mu.

He used to think that the legendary cultivation methods that could overwhelm the sea and control the wind and rain were all illusory fairy methods.

However, in this view, those cultivation methods were negligible compared with North Sea Lost Knowledge.

What's more, North Sea Lost Knowledge was only the first Lost Knowledge in the Nine Absolute Scriptures.

The first Lost Knowledge was so horrible, then how great would the next nine Lost Knowledge be?

"This is bragging, isn’t it?" However, it was just because of that such descriptions were too exaggerated and Lin Mu found it hard to believe.

"You are too superficial." An old voice suddenly came into Lin Mu's consciousness.

"Who? Who is talking?" Lin Mu was startled. He felt creepy and instinctively looked around.

"Don't look around. I'm in front of you." The old voice sounded again.

Lin Mu looked ahead and was horrified. He saw the dragon flying dagger in front of him suddenly emitting heavy glory.

A lonely human figure came out from this heavy glory.

The figure did not have any extra action and he just walked so calmly. He had a pressure that smothered Lin Mu. Under this kind of pressure, Lin Mu was unable to produce any idea of resistance.

"You...who are you?" Lin Mu's mind trembled.

"I am not human." The figure completely appeared in front of Lin Mu and this was an elder.

"Are you a ghost?" Lin Mu's pupils were widened slightly.

"You can also say so. My present form is the body of the soul. I am almost a ghost." The mysterious elder said slowly.

"Ghost?" Lin Mu changed his face and his eye showed fear, "What exactly do you want to do?"

The mysterious elder's breath was so terrible and he claimed himself to be a ghost. It inevitably reminded Lin Mu of some secret stories recorded in ancient books about borrowing someone else's body to restore Yang qi.

"Borrowing someone else's body to restore Yang qi? That is just a devious method. I am from Wangwu Mountain..."The tone of the mysterious elder was full of disdain. But before he finished speaking, he stopped and turned into a sigh, "Forget it, what I said had no meaning at all. At present, I am only a wisp of thoughts. Even if I want to borrow someone else's body to restore my Yang qi, I cannot do it."

"Well, that's good." Lin Mu was relieved. He could hear from the tone of the elder that he really didn't look like he wanted to borrow someone else's body to restore Yang qi. Otherwise, with his horrible breath, if he wanted to borrow someone else's body to restore Yang qi, he could directly do it. He didn't need to say such nonsense at all. Lin Mu thought of the elder's previous unfinished words and asked curiously, "Elder, what sect is the Wangwu Mountain you just said? Is this the legendary hidden sect?"

As a man from a noble family, Lin Mu certainly knew more than ordinary people.

He knew very well that although noble families were very powerful in the secular world, they could not do whatever they wanted in this world. Because there were hidden sects above noble families.

"Hidden sects?" The mysterious elder smiled faintly and said noncommittally, "These things are not important. What you should know more now is the Immortal-Killing Flying Dagger."

"Immortal-Killing Flying Dagger? You know the name of this dagger?" Lin Mu's eyes sparkled.

"Of course, I am its former owner." Lin Mu was shocked by the mysterious elder's words.

"The universe is vast and contains many different worlds. The world in which the Immortal-Killing Flying Dagger and I lived is called the Galactic World. There is a life Ancestor Star in the Galactic world and there is a long river named Yellow River in it. The Yellow River is actually an Ancestral Dragon, which is the source of civilization and the spiritual meridian of heaven and earth. The Immortal-Killing Flying Dagger is also called the Ancestral Dragon Flying Dagger. For the sake of the origin of Ancestral Dragon, I often meditated the Taoism by the Yellow River. I had the privilege of sensing its existence and taking it out. However, my virtue and chance were not enough, and I have never been able to unlock the secret of this dagger."

Lin Mu was convinced of this. Because the mysterious elder obviously didn't know the secret of the Nine Absolute Scriptures.

"One hundred and sixty years passed in a short time, my cultivation base has finally reached its peak. After a sufficient arrangement, I am ready to break up the void and travel to the universe." The mysterious elder continued.

"But I didn't expect when breaking the void, the breath of Immortal-Killing Flying Dagger was exposed, which attracted the coveted ancient god beast Kun Peng. Kun Peng was so powerful that I fought with it until my soul was broken and only slightly injured it. Also, at this moment, the Immortal-Killing Flying Dagger that was stained by the blood of Kun Peng woke up. At that moment, I suddenly realized that the blood of Kun Peng was the starting point to stimulate the Immortal-Killing Flying Dagger. Unfortunately, I woke up too late. My soul was broken and I couldn't live. After awakening, the Immortal-Killing Flying Dagger pierced Kun Peng's body with one strike, and at the same time, opened the void passage, bringing Kun Peng and itself to this world."

"When I was at the bottom of the lake earlier, my consciousness felt vague that Meteorite Lake seemed to be a monster's wound. Does..."

Lin Mu's mind became messy and a frightening thought came into being.

"You're right. The Spiritual Martial Continent is on Kun Peng's back. Meteorite Lake is the wound that was cut by the Immortal-Killing Flying Dagger."

The mysterious elder seemed to have seen through Lin Mu's thoughts and soon confirmed his thoughts.
