Timely update, Lin Feng has always been very confused about his 'ability'.

Although it is very strong against the sky, it does not belong to the five major origin energies.

On that day, at the ancient ruins of 'Hualong', I walked not the five-color overpass that represented the original energy.

But......

One of the four Void Sky Bridges.

In "Warcraft Record", there are 180 million kinds of Warcraft in Douling Shijie, each with its own characteristics. For example, the 'Black Mist Demon Dragon' has a talent in the way of time, and the 'King Kong Ant' has a talent in the way of power. Many of the demonic beasts above the third level have unique 'talents', among which the word 'Dao' has been mentioned many times.

"The way of time, the way of space, the way of power, the way of spirit. Lin Feng's eyes were blazing.

As mentioned, there are a total of four 'paths', just like the four paths of cultivation.

Before fighting the 'Black Mist Demon Dragon', Lin Feng didn't know what this meant.

But now, it is deeply understood.

"It turns out that the so-called 'Dao' is actually a kind of heaven and earth energy, an attribute of the soul heart, or-"

"Directions. Lin Feng's eyes were bright.

During this period of cultivation, I clearly understood that the cultivation of the soul heart was actually the process of absorbing the energy of heaven and earth to 'strengthen the soul of life'. Just as metal, wood, water, fire, and earth are the five most primordial energies of heaven and earth, which constitute the foundation of cultivation, then the four 'heaven and earth energies' of time, space, force, and spirit, are the same path.

The path of cultivation.

...

Lin Feng, enlightened!

Looking at the pitch-black Neidan in his hand. The luster is crystal clear, and Lin Feng's eyes are full of scorching color.

Obviously, this feeling of blood connection is a kind of involvement of the 'Dao', and the inner Dan of the Demon Beast is actually similar to the soul heart of the martial artist.

"What if I devour it and refine it?" a crazy thought came to mind. Lin Feng hesitated a little.

Once upon a time, he accidentally ate the 'dragon spirit' and almost caused a tragedy.

Dragon's 'stuff'. Apparently not so easy to 'digest'.

In particular, Neidan is the essence of a dragon.

"The heaven and earth energy contained in this 'Neidan' is the same as the 'attribute' of my soul heart. It should be able to achieve an improved effect, and maybe it will be very good. Lin Feng thought lightly in his heart, his brows furrowed slightly, and he knew very well that this was an 'opportunity' and a 'challenge'.

But at the same time, it is quite dangerous.

The essence energy of the dragon, the origin of cultivation, is it a joke?

If one is not done well, it is possible to explode and die!

Lin Feng clenched his fists, and a hesitation flashed in his eyes. Suddenly-

His complexion changed slightly, and Lin Feng showed a look of surprise.

"Black Mist Crystal!" Lin Feng's eyes lit up.

There was an extra black and translucent diamond-shaped spar in his hand, and when he held it in his hand, he also had a feeling of blood connection, but compared to the feeling of Nedan. But it's far from it. Just like the difference between crude iron ore and refined iron ore, the 'purity' is not the same.

"The Black Mist Crystal is formed by the alienation and fusion of the 'Black Mist' of the Black Mist Demon Dragon. Lin Feng said secretly.

If the Black Mist Demon Dragon's 'Neidan' can raise his soul heart level, then the Black Mist Crystal can also do the same!

"Give it a try!" Lin Feng nodded.

Compared to the hesitation of the 'Neidan', the black mist crystal did not make itself feel any 'danger'.

Swallow it down. Lin Feng's eyes flickered.

Suddenly-

An extremely strong mixture of energy came straight into his mind, with a violent aura, like an 'intruder'.

"Sure enough. Lin Feng said lightly in his heart, the sharp rotation of the soul heart, in an instant, the fourth layer of the "Soul Secret" heart trick was cast at will, and the violent mixed energy was entangled by the rotation of the soul heart, forming a black mist, rotating around. ...,
