In an hour's time, the vitality of the entire tree was deprived by Li Xuanfeng.

The emerald green tree, which was full of vitality, has turned into a dry branch, and as soon as the wind blows, it turns into a pile of powder and scatters.

Looking at the more than a dozen emerald green beads of different sizes in front of him, and feeling the vitality essence contained in them, Li Xuanfeng no longer hesitated, picked up one and swallowed it with his mouth open. Among the five elements, the wood attribute originally represents vitality, and the green beads condensed from the big tree contain its century-old life essence.

For the current Li Xuanfeng, it is a great supplement.

As soon as the green essence entered the body, it quickly replenished the vitality lost in Li Xuanfeng's body due to the extraction of essence blood, and a cool and comfortable feeling suddenly spread throughout his body, making him can't help but almost moan.

Li Xuanfeng didn't dare to slack off, closed his eyes, silently used Xuangong, and as he gradually got better, his body seemed to form a black hole. All the energies that are free from heaven and earth, such as the aura of heaven and earth, the essence of the sun and the moon, the essence of plants and trees, and even the evil qi, yin qi and other energies, seem to be summoned and come one after another.

Above Li Xuanfeng's head, a colorful storm of power was formed, and countless energies poured in from his Heavenly Spirit Acupoint, nourishing his body, muscles, and even cells, muscles and bones.

With the influx of various forces, Li Xuanfeng's whole body and muscles and bones sounded, and his entire body size expanded more than once, giving him a feeling that he was about to be blown up.

Li Xuanfeng had no joy or sorrow, he didn't pay any attention to the pain in his body, and still ran the exercises silently!

Under Li Xuanfeng's control, the huge power was refined into chaotic qi, constantly washing away every bone in his body, and the Nine Transformations Creation Gong was running at full strength, and he was hungry and thirsty to incorporate this aura and medicinal power into his bones.

Soon, the bones gradually lit up with jade-colored light.

Over time, all the life beads and the various powers that came from the wind turned into chaotic qi and were absorbed by the bones of Li Xuanfeng's body.

The jade-colored brilliance on the bones became more and more prosperous, and finally all the 204 bones on the whole body were enveloped, and a mysterious change gradually evolved in the interior of the bone marrow, and finally the brilliance on these bones shone brightly, like jade, and the aura was contained.

As the first practice in the world, although the Nine Transformations Creation Gong is practiced both inside and outside, it is more important to practice the body, only when the body is strong, can it take itself as the cornerstone, embrace all rivers, absorb thousands of laws, and finally prove the Tao with strength!

The physical training part is divided into two parts from the inside out.

The first part is the three stages of bone refining, tendon training, and viscera training! After the first part is completed, you can enter the second part of cultivation! The second part is divided into nine layers, and each layer is divided into three stages: the beginning, middle, and the last, and the conditions for cultivation are extremely harsh!

Li Xuanfeng has only obtained the cultivation method of the first layer now, and the first layer alone makes Li Xuanfeng's scalp tingle, and he has an urge to die.

The primary level is to temper the flesh body with the help of fire and ice, and after completion, invulnerability is trivial, and with the strength of the flesh alone, it can be compared to a master in the early stage of foundation building.

In the middle stage, it is even more perverted, not to mention the power of thousands of years of ice, but also through the true fire of samadhi, constantly refining the physical body. After Dacheng, with his physical strength alone, he can compete with the masters of the Jindan period.

This is practice, it's just self-harm!

And the first layer alone is so perverted, how afraid is it in the back, Li Xuanguang couldn't help but shudder when he thought about it!

On the horizon, the morning glow rises, and the mist is thick.

The time of the night passed quietly, the jade color on the bones and bone marrow was smoother and more abundant, Li Xuanfeng swallowed all the remaining green beads in one gulp, and frantically ran the exercises!

All kinds of forces between heaven and earth surged towards him more quickly, and such a huge inflow of power made Li Xuanfeng very happy in his heart, and he guarded his mind at the moment, allowing the huge power to pour into his body, and the Nine Transformations Creation Gong was running at full strength, refining this experience into chaotic qi with hunger and thirst, and then incorporating it into the bones of his body.

Chaotic qi flowed in, and the bones that were originally as white as jade, and the bones that emitted a misty jade-colored light instantly brightened, and the color became darker and darker.

With the passage of time, the bones and bone marrow of the whole body are all jade, and the light on them is flowing and crystal clear.

"The bone refining is complete. ”

Li Xuanfeng opened his eyes, and his happy expression could not be concealed! Carefully feeling the huge power contained in the lower bones, Li Xuanfeng once again sighed at the subtlety and strength of the Nine Transformations Creation Skill, and looked forward to the future realm even more.

"Next, it's time to practice qi!"

Paying attention, Li Xuanfeng stood up from the ground and continued to walk towards the top of the mountain, although Li Xuanfeng, who had refined his bones, still looked like an old man who was about to die, but he was full of strength, and he no longer had that panting and dying appearance when he walked.

The aura and various powers between heaven and earth are scattered between heaven and earth, absorbing and refining them, not to mention that those powers are not as good as the essence contained in the ancient tree.

If he wants to make great progress in a short period of time, he can only pay attention to the ancient trees that are more than a hundred years old.

As for the ancient trees that are less than a hundred years old, the life essence contained in them is too little, and it takes chaotic qi to condense it, which is really more than worth the loss.

Aura is not static, some places are thin and not suitable for cultivation, and some places are enriched and become a blessed land. And all things in heaven and earth depend on the aura of heaven and earth to survive, and even ordinary people will like places where the aura is abundant, which is good for the body. Therefore, the stronger the aura, the more ancient trees will be aged.

Walking along the mountain range, Li Xuanfeng carefully sensed the changes in his aura, and after about twenty minutes, he finally stood still.

In front of him was a big tree that four or five people couldn't hug, about twice as big as the one he had originally refined, I am afraid that it had grown for four or five hundred years, and its crown was huge, blocking the sun, even if it was autumn outside, it was still refreshing here.

"The harvest is not bad, these ancient tree essences, because they should allow me to enter the middle stage of Qi cultivation!"

Li Xuanfeng consumed most of the chaotic qi, turned into almost an hour's time, roughly counted, and found that there were almost forty green beads condensed from the life essence, and the harvest was almost twice as much as that of the previous ancient tree.

Obviously, this ancient tree is much older than that one.

Sitting down cross-legged, Li Xuanfeng opened his mouth and swallowed a bead, which was full of huge vitality and exploded in his body in an instant.

Li Xuanfeng closed his eyes and silently used Xuangong, and the chaotic qi in the dantian flowed into the meridians, enveloping that huge force and wandering along the meridians!

In this way, after a great week, the huge power containing vitality was reduced by one point, and the gray chaotic qi was strengthened by one point!

Night fell quickly, and Li Xuanfeng, who was cultivating, completely forgot the existence of time, and kept running Xuangong, the beads in front of him continued to decrease, and the chaotic qi in his body became stronger and stronger!

Time passed, the sun and the moon rotated, and another night passed. Li Xuanfeng, who was sitting still, suddenly opened his eyes, and in his eyes as black as ink, it seemed that two rays of essence shot out, piercing through the void.

The mouth opened, and a white air flow rushed out, stretching for several meters, making a 'hiss' sound in the void, as if shooting through the air.

This white practice lasted in the air for a few minutes before it gradually dissipated.

"Finally entered the middle stage of Qi cultivation!" Feeling the strong chaotic qi in the lower dantian, Li Xuanfeng sighed, and his heart was very sad.

Although the Nine Transformations Creation Skill is against the sky, the difficulty of cultivation is far beyond the comparison of other exercises!"

When he was cultivating, Li Xuanfeng found that the chaotic qi was too advanced, if it was calculated according to refining a trace of heaven and earth aura, he could cultivate half a trace of true yuan. Li Xuanfeng cultivated a trace of chaotic qi, and he had to refine almost a hundred traces of heaven and earth aura!

That big tree was at least a few hundred years old, and although it had not been transformed into a spirit tree, it had been nourished by hundreds of years of spiritual energy, and the life essence contained in it was absolutely amazing. The quality is also much higher than that of the aura, but it is far less than the chaotic qi, and it takes almost a few tenths of the life essence qi to transform into one point of chaotic qi.

According to Li Xuanfeng's estimate, if he was cultivating other cultivation techniques, he could directly rely on these essences to enter the late stage of Qi cultivation!

This is only the beginning of cultivation, and the further you go, the more difficult it becomes, and the more energy you need.

Before practicing qi, it was good to say that the life essence of these hundred-year-old trees could support his rapid progress.

But when it comes to building the foundation, according to Li Xuanfeng's estimate, the effect of these ancient tree essences on him will be reduced by at least half!

After that, the effect of these essences on him is almost negligible!
