In the last life, since Ye Feng obtained the Huangdi Neijing practice, he was very curious about ancient martial arts practitioners and had searched for ancient books to verify.

So I also learned some aspects of cultivation. True Qi is an energy obtained by ancient warriors through their own practice.

It can be said that some ancient martial arts masters could have true energy.

But transforming true into Yuan, the vital energy here refers to an energy close to the elementary power of heaven and earth.

At this level of energy, it can no longer be obtained by practicing by one's own practice, but requires talent and luck, as well as an understanding of the nature of the world.

From the transformation of true qi to the vital energy, one can use the vital energy to mobilize the energy between heaven and earth and attack, and the power is simply not comparable to that of true qi.

Of course, these things are just Ye Feng's speculation. As for the specific situation, we have to wait for the complete transformation of the golden heart to be completed before the experiment can be conducted.

But no matter what, it is a good start.

At this moment, the golden heart finally made no trouble. With the continuous supply of energy, it continued to shrink in rapid beating, and continuously purified the true qi in Ye Feng's body into vital energy.

Ye Feng was constantly practicing, swallowing evolutionary meat to provide energy to the golden heart. In a blink of an eye, two hours passed.

During these two hours, Iyalan's mood was definitely up and down.

At first, she thought something was wrong with Ye Feng herself, especially when the golden heart began to transform and beating violently, she was even more shocked.

Fortunately, Ye Feng had no other reactions, which made her gradually feel at ease.

But this peace of mind lasted not long, and her heart rose again because she saw Ye Feng constantly swallowing the evolved meat.

If it is a normal refining and evolutionary meat, that would be fine, but Ye Feng's speed of swallowing evolutionary meat was too fast.

Ye Feng's speed of swallowing 1 piece of evolutionary meat in one and a half minutes made Yiyalan feel frightened. If it were another person, he would probably not have to swallow 10 pieces of evolutionary meat, and the huge energy inside would burst out the meridians.

However, when she watched Ye Feng swallowing the evolutionary meat at such a speed for an hour, not only did nothing, but the aura on her body continued to rise, she became a little numb.

Now two hours have passed, and the evolutionary meat that Ye Feng swallowed has been no less than eighty fast. After swallowing so much evolutionary meat, Ye Feng's aura has approached the late stage of the third level. Under such circumstances, a smooth breakthrough can be achieved in at most one hour.

After Yiyalan observed Ye Feng's situation again, she turned her attention to the dense forests on both sides.

Ye Feng started practicing around 5 pm. At this time, two hours passed and it was already 7 pm.

Zombies are particularly active at night. Even though Iyalan has defeated three waves of zombie animals shortly after nightfall.

There were hundreds of zombie corpses lying on the ground.

Although it is not difficult to repel these zombie animals with the help of the giant panda national treasure and the yellow cat, according to Ye Feng's state, I don't know when I will wake up. If I really encounter a large wave of zombie animals, then things will be troublesome.

Thinking of this, Iyalan picked up the lacerator rifle in his hand and came to the side of the national treasure.

"National Treasure, go there and push those cars over. Let's build a simple line of defense here." Yiyalan said with her finger at the vehicle not far away.

Unfortunately, although the national treasure has already activated its intelligence, it does not understand human language. Even if Ye Feng communicates with it normally, it can only be done with the help of the evolution box.

So at this time, one person and one panda stared at him with big eyes, but Yi Yalan couldn't command him at all.

Five minutes later, Yiyalan's saliva was dry, but the giant panda national treasure still looked at her with his innocent eyes, with an unknown expression on his face.

In the end, Iyalan was defeated by it and could only push the cart by herself.

Fortunately, although Yiyalan is a supernatural being, she has reached the fourth level. In terms of power, she can also be comparable to two or three great men.

Even though it was very difficult to push a car, she could still barely push it. For Ye Feng's safety, she could only hold on now.

Ye Feng, who is in a state of cultivation, is not clear about the situation here of Yiyalan.

After two hours of transformation, the golden heart has been smaller, not much bigger than the fist.

As it becomes smaller, it beats more and more powerful, and the true energy in the body is constantly converted into vital energy with the beating of the golden heart.

At this time, the amount of vital energy in Ye Feng's body had reached nearly half. As the vital energy increased, Ye Feng was surprised to find that these vital energy was not only wandering in the meridians, but spreading to the whole body.

Every inch of the body's bones and flesh are gradually undergoing transformation under the nourishment of these vital energy.

This transformation is magical. In addition to enhancing the strength of the body, it also gives Ye Feng's body another special change.

Ye Feng was not sure about the specific effect of this change, but as his body changed, Ye Feng felt that his body seemed to be getting closer and closer to this world, which made him feel a trance-like feeling, as if he was going to integrate into this world.

As this feeling increases, Ye Feng entered a special state in a daze. In this state, his body's transformation is getting faster and faster, and a feeling of comfort comes from his whole body.

Ye Feng didn't know how long this feeling lasted. It was not until at some point that the golden heart in his lower abdomen suddenly shook, and he shook out of that special state.

When Ye Feng focused his mind inward again, he was surprised to find that the golden heart on its lower abdomen had actually turned into the size of a thumb.

At this time, in Ye Feng's feeling, the thumb-sized heart seemed to have completely become an entity, and at least in his spiritual perception, there was no longer any illusory feeling.

And more importantly, at this time, he already felt a blood-connected feeling for this golden heart, as if he should be part of his body.

As long as he wants, he can urge the golden heart to beat at any time.

This surprised Ye Feng very much, but when he felt this golden heart carefully, the surprise turned into astonishment.

Because in his perception, although the golden heart is only a small size, it stores a lot of vitality.
