Su Yi didn't do it immediately, but first collapsed the hole a little and sealed himself.

If an enemy does attack, the blocked hole will not stop the enemy, but it can at least give him some warning.

He wasn't worried about the air or other reasons, in fact, up to now, he might not have gotten the so-called 'Bigu' stage for human monks, but the consumption of air was not so great.

The air in the long cave was enough for him to consume for three months.

And he estimated that it would not take him that long to make the cut.

Walk to the inside of the cave, spread the spirit stone on the ground, and surround it into a small bed, and the next side of the 'spirit stone bed' is full of spirit fruits.

Most of this spirit fruit is the reserve of the thunder bear, and some are newly picked by the rabbits from the territory of the thunder bear.

As a high-level demon clan whose strength far exceeds that of ordinary demons, Thunder Bear's territory is huge, five times larger than ordinary demons!

Lingzhi naturally has a lot more.

Su Yi took a deep breath, quietly lay on the 'spirit stone bed', and slowly closed his eyes.

A few sounds fell into Su Yi's ears, including the footsteps of rabbits, the chirping of birds in the mountains and forests, and some miscellaneous things.

However, his mind did not fluctuate in the slightest, just lying quietly on his stomach, feeling the surge of aura.

The energy points accumulated early in the morning were continuously converted into true qi, rushing like rivers and seas in the body, making a few sounds.

The sound of heartbeat was clearly audible, with Su Yi's own heartbeat and the slow but powerful beating of Jair's heart.

It's a pity that Su Yi turned a deaf ear to everything.

In this truly calm environment, Su Yi felt the existence of incomparably vast spiritual power between heaven and earth.

They are everywhere, integrated into everything, and guide everything in the world.

It is an extremely troublesome thing for human beings to feel the aura of heaven and earth, and it takes a long time for the strongest genius to comprehend.

And for the beasts that are often ridiculed by humans, feeling the aura is the most basic thing.

Because they are part of nature.

[Ding Dong, the host obtains the skill 'Swallowing the Sun and Moon Essence' through perception.] 】

[Ding Dong, the host obtains the skill 'Aura Exhalation' through perception.] 】

[Discover the host's original skill 'Refining and Refining Qi', and integrate the skills 'Swallowing Sun and Moon Essence' and 'Spiritual Qi Breathing' into the skill 'Refining and Refining Qi']

['Refining and refining gas' has been strengthened.] 】

[Refining and refining qi: You have discovered that the aura outside the body can also be used as a type of essence, and you have noticed the mystery of swallowing and exhaling aura!]

[You can already convert the aura, the essence of the sun and the moon, and the essence (food energy) in the body into your own true qi. 】

The system's prompts sounded silently, but Su Yi turned a deaf ear and turned a blind eye.

He just quietly guided his true qi, constantly strengthening his body, and at the same time converting all the energy into his own true qi to replenish his consumption.

The method of improving true qi is very simple, as long as you continue to consume true qi and strengthen your body with true qi, the amount of true qi that your body can hold will naturally increase.

That is, the so-called - cultivation!

Simple, boring, and indispensable.

Su Yi slowly inhaled and exhaled.

Between this exhalation and inhalation, the surrounding aura was constantly absorbed and swallowed by him, constantly strengthening himself.

Although the density of the spiritual energy in this cave was not bad, it could not meet Su Yi's consumption.

The spirit stone under him also gradually escaped the spiritual energy, filling the void that seemed to be a bottomless pit.

Power Points, Aura, Spirit Stones......

The simultaneous consumption of the three finally raised Su Yi's cultivation speed to a point that was far beyond his reach before!

I don't know how long it took, every cell in the body was filled with that endless stream of true qi.

Finally, quantitative change leads to qualitative change!

The true qi is all over his body, and he begins to exude a sense of sharpness!

Su Yi opened his eyes and stood up.

In the environment of the mine, there was already a lot of dust, and he lay quietly, and he didn't know how long it had been, and his body was full of ups and downs.

However, his eyes were incomparably bright!

"Advanced!"

The current Su Yi is a demon!

[Dingdong, the host advances to meet the evolutionary requirements.] 】

[Whether to integrate the bloodline into the host bloodline.] 】

"Integrate. Su Yi said calmly.

In an instant, the black steel pig bloodline, green willow bloodline, blood jackal bloodline, etc. on the system template all turned into fragments, as if thrown into a whirlpool and disappeared.

Then, that translates into a powerful thrust!

"I don't know what bloodline I can get?" Su Yi squinted his eyes and quietly waited for the result.

Evolutionary bloodline is not just a proper noun for Su Yi alone, but a common characteristic of the entire demon clan.

Of course, it can also be described as: Ancient Bloodline Awakening!

The simplest example is a snake.

Snake, a thousand-year-old dragon, a 10,000-year-old dragon!

This is a kind of bloodline purification, which can also be said to be an evolution.

Another example is the thunder bear, which is said to be the bloodline of the Thunderstorm Bear, if this matter is true, the thunder bear continues to cultivate, and has been promoted, and one day he will awaken the bloodline of the Thunderstorm Bear.

But Su Yi is different!

After the system integrates the bloodlines of various races, it is definitely stronger than advancing alone!

And, too, fast!

When the snake turned into a Jiao, it was absolutely impossible for him to directly turn into a Jiao when he was promoted to a demon for the first time.

But Su Yi can!

"I just don't know why I will evolve ......" Su Yi squinted.

In fact, up to now, almost 99.9999% of the demon clan is mixed-race.

Most of them are demon hybrids, and some may be shemale hybrids, real pure-blood demon clans, almost few of them are pitiful.

Maybe there may be tens of thousands of demon clans in the body of a demon.

Such a hybrid will often be made into a new demon clan name, such as the thunder bear, which should be a hybrid between the Thunderstorm Bear and a certain existence.

Of course, it is more likely that it is a hybrid of the Thunderstorm Bear, combined with the hybrid of a certain demon clan, or even a hybrid of the Thunderstorm Bear, combined with a hybrid of the Hybrid Thunderstorm......

After mixing like this countless times, at a certain node, he became a demon clan - Thunder Bear.

Countless years have passed, theoretically all the demon clans have been mixed together, and there are almost no unique hybrids that have not yet been mixed.

Su Yi felt that it was very likely that he would combine a bloodline that had already been mixed up based on the fused bloodline and his own bloodline.

Of course, it is also possible to evolve into an unknown species......

[Ding Dong, the bloodline fusion is complete, please choose one of the following three options as your evolutionary race.] 】

"I actually returned the one I chose. Su Yi was stunned.

[Option 1: Phantom Tiger (Second-Order Demon Bloodline): Known for its strong mental power, proficient in illusion-like supernatural powers, it can feed on the emotions of other creatures. 】

[Option 2: Silver Blood Dolphin (Second-Order Demon Bloodline): Has blood-like magical powers, which can hook out the blood of others for your own use, or consume blood to restore injuries. 】

[Option 3: Snowy Night Polar Cat (Third-Order Demon Bloodline): Grows in the extreme north, moves quickly, is good at concealment, walks silently, has ice and snow, speed supernatural powers, and is a night killer. 】

Note: The bloodline level of the demon clan is to grow to a certain level with the help of bloodline without being killed by external forces.

The bloodline of the second-order demon clan can grow to the second-order demon clan!
