The system gives me immortality, and I will eventually become invincible while I’m alive.

Half a day later.

"Xiao Chi."

"Brother Xun?"

"Lend me a drop of blood."

"it is good!"

Without saying a word or even asking the reason, Xiao Chi forced out a drop of blood essence from his body and handed it to Chen Xun.

However, after breaking through to the Nascent Soul stage, the body sublimates, and every drop of essence and blood is extremely precious, and recovery takes a long time, especially the recovery of spiritual beasts, which requires a lot of precious elixirs.

Xiao Chi felt a lot sluggish in an instant. The big black cow mooed twice and was already selecting elixirs in the storage room. There were too many thousand-year-old elixirs.

"Old Niu, take care of Xiao Chi." Chen Xun carefully collected the drop of blood essence into a jade bottle, and finally placed it in the Heling Tree box for storage.

"Moo?" The big black bull nudged Chen Xun, and asked what he was doing with his blood.

"I have opened up my body aperture, but the power of the Heavenly Tribulation body tempering has been exhausted when it reaches the limit of our body refining and foundation building period."

As soon as Chen Xun opened his mouth, his flesh and blood shone with gleaming light. Every inch of his skin seemed to have been polished, as flawless as jade, and full of unimaginable power.

He began to explain to Da Hei Niu that the strength bonus points of their system could finally be used, and the bonus points from the body training techniques began to increase exponentially.

Chen Xun can collapse a mountain with one punch without using his magic power. Even if the power of the Five Elements is exhausted, he can still challenge the Yuanying monk head-on. If he can't be beaten to death, he will run away!

Xiao Chi was still a little sluggish, but was deeply attracted by Chen Xun's arm.

There seemed to be rotating acupuncture points in the gleaming light, looming, and the majestic power of qi and blood circulated back and forth in the apertures.

"Brother Xun...he's not a human race, is he?" Xiao Chi secretly swallowed. He had collected corpses from many human races over the years. How could the structure of other people's bodies be like this?

It's eyes widened, and it couldn't understand something like the Heavenly Tribulation Tempering Body, but it didn't care about it. It was now becoming more and more certain that Brother Xun was not a human race.

He may be a creature he has never seen before, but he has the form of a human race!

Xiao Chi thought about it and suddenly felt happy. No wonder it always felt that Brother Xun was completely different from these human races, whether it was personality or behavior.

"Old Niu, I may want to collect the essence and blood of all spirits, or maybe all races..."

Chen Xun spoke solemnly, with unprecedented seriousness in his eyes, "But the compensation must be in place, so as not to bring disaster to those intelligent races."

This is a plan that is unimaginably vast, but it will never be like those described in the body-training techniques, which involve using blood to irrigate one's body, drawing blood to refine bones, and bringing catastrophe to other people's races.

He has now opened 80 body orifices in his body, and the power of Qi and blood begins to circulate in these acupoints, circulating back and forth.

Chen Xun naturally knew that he was becoming less and less like a human race, but this was a world of immortal cultivation, full of endless mysteries. He only needed to keep his heart, and exploration was the most important thing.

Moreover, his appearance has not changed. He is still the human Chen Xun, and his brothers are also high-spirited. Nothing has changed, and that is enough.

"The essence and blood of all races..." Xiao Chi opened his mouth wide, Brother Xun was a little too crazy.

"Moo~~"

The big black cow nodded heavily and had no doubts about Chen Xun's decision. Even if it was asked to take a drop of Buddha's blood essence, it would try it without hesitation.

"There is a great secret to body training. I don't know what secrets we can discover if we go on together."

Chen Xun's eyes flashed, and he looked at the big black cow with a burning gaze, "Old cow, I want to cultivate a rootless essence flower, so I need the essence and blood of all races. The method is all summarized from these body training techniques. ."

He took a deep breath, which became quite deep, and told Da Hei Niu about his insights over the years.

Chen Xun has discovered that the secrets of quenching the body with elixirs during the Qi refining period and irrigating the body with the flesh and blood of spirit beasts are inextricably linked to the essence of heaven and earth.

"Moo~~~" The big black cow snorted. As expected, the eldest brother discovered the great secret of the world again.

Xiao Chi was sweating heavily on his head. He couldn't understand it at all, but from some of the sentences he could feel that Brother Xun's future might be a bit scary...

hum!

Suddenly, air currents came from all directions between the sky and the earth, but there was no pressure. Chen Xun was raising his hand at this time.

His blood was boiling crazily, and his body was indescribably powerful and otherworldly.

Xiao Chi and Da Hei Niu looked at each side with dumbfounded eyes. The air flow was so strange, but they were converging towards Chen Xun's body.

At this time, a large amount of air flow gathered in front of Chen Xun and formed a cloud of icy light. He suddenly inserted his hands into it, with a slightly painful expression on his face.

"This is the essence of heaven and earth. The spiritual energy of heaven and earth is inspired by one's own spiritual roots. The essence of heaven and earth...is inspired by one's own majestic energy and blood."

Chen Xun explained word for word, his words were sonorous and powerful, "But to condense this rootless flower of essence and energy, the energy of the five elements, the power of the body tempered by the heavenly calamity is the key. Without cultivating the five elements, it is difficult to touch the path."

"Moo~~" Da Hei Niu stood beside him and nodded without blinking. The energy of the five elements is the perfect medium, and the aura with attributes must be transformed into the aura without attributes between heaven and earth through it.

It snorted heavily, and the knowledge accumulated over the years was finally connected. The longer you live, the better!

Xiao Chi had a look of confusion in his eyes, and looked at his body to see what essence was and what the five elements were. He also practiced body training and spiritual energy, so why had he never felt it before?

The memory in the bloodline inheritance also had nothing to do with what Brother Xun said. Its mouth opened wider and wider, with a confused look on its face.

Not long after, an illusory glazed rootless essence flower was taking shape in mid-air. It was surrounded by sparkling lights and falling, which was quite confusing and dreamy.

"In the past fifty years, and the next thirty years, I have been comprehending the essence of heaven and earth, but it is like rootless duckweed. My body cannot absorb this essence of heaven and earth at all."

The corner of Chen Xun's mouth slowly raised, showing the big black cow step by step, "However, how can I waste this gift from heaven and earth, use my own Qi and blood as the root seed, and use the Qi of the Five Elements to pull and plant flowers!"

"Moo!" The big black bull's eyes widened. He was still thinking about how it would take so many years to study a body-training technique with his current strength and understanding.

It turns out that he is practicing this. The twists and turns may be much more troublesome than what Chen Xun said. Every time the elder brother teaches it, he has integrated it.

Their Five Elements spiritual roots are also five flowers. The eldest brother must have discovered something from them and connected them.

"But this flower has not yet taken shape. It must be watered with essence and blood, just like refining the body. I also had a sudden idea after seeing those elixirs to temper the body."

Chen Xun took two steps, and the illusory rootless essence flower also floated up. "When it truly takes shape, we can start cultivating it and open up a unique path to body refining!"

Because he has tried it before, but the essence of all things has no effect on it, and it is still the carrier of the essence of heaven and earth.

As for how to shape it, we can only try following the ideas of the sages and collecting blood essence.

He had electrocuted many snakeheaded fish over the years. After forcibly extracting a drop of sperm and blood, there was some reaction when he irrigated it. He tried several times later, but there was no reaction.

Then he obtained the essence and blood of several sea beasts, most of which were in the foundation-building stage, but they were really effective.

He speculated that quality rather than quantity is what matters in shaping, and eventually he gradually came up with the idea of ​​collecting the essence and blood of all races.
