Lin Feng then immediately recalled the life energy that had previously been absorbed, that life energy contained both the physical energy and mental energy of a human.

“I can suck their life energy forcibly by using the eyes of these green ouroboros snakes, even so, I still don't know if this cultivation world has any knowledge of the life energy in human bodies. If they only cultivate physical energy, mental energy, and natural spiritual energy then that means they are completely unaware of the existence of this life energy.” Lin Feng was already sweating profusely like he had been washed away by rainwater after repeated training, even so, his brain still couldn't stop thinking.

“Then there's still the problem with my martial arts if it's true that I have as many as 7 spirit element roots but I still don't know how to do it. With this mysterious life energy, it seems I need to develop my own spell.” Lin Feng had been lying on the ground with his eyes facing the sky.

The morning training exhausted Lin Feng, but he still didn't want to waste his time other than cultivating. Lin Feng wants to strengthen himself as quickly as possible, should at least be able to have the power to protect.

After lunch, Lin Feng returned to the room and began to get an idea of ​​a technique that was easy in his current strength capacity. With the power of the eye of the green ouroboros snake, he can use his life energy to invade the enemy's body and destroy it from within.

It was the most suitable martial art for Lin Feng's current situation, he didn't need to expend too much energy. Lin Feng only needed to absorb the enemy's life force and restore that power to destroy the internal organs. This martial art should not be underestimated in close combat, even this martial art would be a killer move that no other cultivator at the same stage could imagine.

Then Lin Feng tried some moves that he thought were right, he continued to try different positions that fit in the attack moves. After countless failures and deductions, Lin Feng finally managed to get the results. He managed to do this move smoothly without the slightest mistake, his body has started to get used to this martial art move.

“My first martial art has been created, I will hereby name it absolute breaker. Because no matter how formidable their fleshly bodies are, it will still not be able to withstand the attack energy that directly attacks their internal organs.” Lin Feng said in a happy tone, the feeling of pleasure from successfully making martial arts really excited him. Then Lin Feng retrained the absolute breaker move. Even though his body was getting used to it, what Lin Feng wanted was a Move based on instinct. Even if one day he lost his memory, at least this martial art move should be melted into his bones.

5 days later, in a simple room with only a bed and a table. Lin Feng fell onto the bed with sweat all over his body while gasping for exhaustion.

For the past few days, he had been training the absolute breaker martial art continuously until his body went numb.

“In cultivation, there really are no shortcuts! I who obtained an ancient sigil of the ouroboros snake could be considered the first to discover life energy, but it is very difficult to cultivate this power!” Lin Feng muttered as he wiped the sweat off his forehead.

Although this kind of life was very bitter and exhausting, at least Lin Feng's current life was full of hope for the future. This was better than his previous life in the modern world, a life without a definite purpose that was really very tiring and boring.

After a few days of training and understanding this cultivation world, Lin Feng had a general understanding of what to do.

People in this world mostly absorb spiritual energy from nature and store it in the body, after successfully gathering it they can advance to the next stage. Meanwhile, physical energy is the energy of a cultivator who trains the strength of the body while mental energy is the energy of a person who exercises their soul power.

Lin Feng obtained satisfactory results after observing various things. That life energy does come from the union of human mental energy and physical energy. therefore life energy is very difficult to train, but the power expended by it is 5 times that of the 3 main energies.

“While thinking about it, I suddenly had an interesting idea.

What would happen if I combined the life energy with the spiritual energy of that realm? Therefore I should be able to use the cultivation methods of this world's people, they can absorb nature's spiritual energy into their own bodies” Lin Feng thought of something extraordinary. If the concept was successfully carried out by him, Lin Feng was sure that he would create new energy that had never been done by people in this world.

“But if I wanted to do that, it seems like it would be very dangerous without proper preparation.” Lin Feng could only sigh at how helpless the current situation was.

Lin Feng had so much he wanted to do, but it was a pity that his strength and cultivation level were still so low. Therefore Lin Feng still couldn't do it even if he wanted to.

“Right now I just need to perfect my absolute breaker move, once this is done then I can focus on practicing the natural spiritual energy!” Lin Feng kept repeating the absolute breaker move.

After not knowing how long Lin Feng had practiced indoors, suddenly the door to his room was pushed open. Glancing towards the source of the voice, Lin Feng saw that it was the girl in the same group as him, Mu Yin.

With a portion of food in his hand, Mu Yin entered the room. The little girl glanced at Lin Feng who was practicing while placing the food on Lin Feng's table.

"Thank You!" Lin Feng said it while smiling at him.

After learning of closed-door cultivation these past few days, Mu Yin always took the initiative to deliver food for Lin Feng. But unfortunately, the little girl almost never spoke every time she entered the room, she just put the food down and left.

Unexpectedly, at this time a voice suddenly sounded in Lin Feng's ears.

"You're welcome!" Mu Yin's voice was very small, then the girl turned away very quickly as if very embarrassed by her small voice.

Staring at the little girl's back, Lin Feng began to recall some of the little girl characters in the anime he had watched.

“Is my current appearance scary to that girl?”
