About two hours later, the fighting energy in the entire space had turned yellow, and the yellow fighting energy seemed to be a fusion of clouds, mist and flames, constantly rolling from the inside to the outside.

And one after another, thunder sounds gradually came from the body of the figure in the fighting spirit. If there was another person here, he would clearly remember that the thunder sounds were faintly heard more than ten times!

At a certain moment, the khaki fighting spirit that filled the entire space suddenly shrank and instantly sank into Xu Feng's body, disappearing without a trace, while his whole body was surrounded by a majestic and surging force of qi and blood.

Faintly, his exposed skin became more ancient and crystal clear, his black hair was dark and shiny, a primitive and desolate breath flashed through Xu Feng's body, and he opened his eyes slightly.

"call--"

Exhaling lightly, Xu Feng looked down at the corpse in front of him that had turned gray.

"The growth of Qi and blood power can actually improve the quality of Yuanli slightly. This is an unexpected gain."

After absorbing the blood essence from the body of this mysterious immortal species, Xu Feng discovered that the more powerful the cultivator was, the more helpful the blood essence in his body would be to the Wilderness God Technique.

This ancient method is the real way to practice the Wild God Technique. It is cruel and primitive, and exudes a wild and primitive atmosphere!

However, according to the ancient scrolls, although the ancient human race was powerful, their living environment was still difficult, with all kinds of powerful enemies everywhere. Fighting and death have always accompanied the history of the human race. Therefore, there is nothing wrong with this method of cultivation if it is used in that environment.

Fighting to support fighting is the most suitable way of training in such a dangerous world.

Xu Feng is not a saint, so he has no objection to this. Besides, these immortals are all people who deserve to die, and using their corpses to practice can be regarded as a good use of waste.

This immortal corpse allowed him to open up ten new bloodlines. Now he has eighty-five bloodlines, and is not far from completing the one hundred and eight bloodlines.

However, as the blood vessels increase, more qi and blood power is required to open up a new blood vessel.

But this is normal.

Without being immersed in the joy of this huge improvement for long, Xu Feng flipped his hand and took out a pile of monster corpses collected in the secret realm. These were the corpses he collected when he followed the disciples of the Nixuan Sect to the edge of the secret realm.

There are more than 200 in this pile alone, but the strength of these monsters is generally in the Yuan Refining Stage, and the strongest one is only at the ninth level of Yuan Refining Stage.

But, a little is better than nothing.

After refining it all, Xu Feng only gained three bloodlines.

But he was content.

With a flick of his hand, a wisp of white flame fell on the pile of corpses, almost instantly enveloping the corpses, and then turned them into ashes.

Without paying attention to the corpses of the monsters, Xu Feng set his sights on the corpse of this mysterious immortal species.

Back then, when it was in Shangguan Qingyu's body, he used the method of the God of the Wilderness to refine the qi and blood to extract a trace of immortal essence. The golden bean is now quietly placed in his pendant.

Xu Feng flipped his hand and took out a wisp of immortal energy from Shangguan Qingyu's body, which was the golden bean the size of the little finger nail.

This is the crystallization of all the immortal energy in Shangguan Qingyu's body. However, just this strand of it was enough to shake the energy in his body greatly at the time.

Thinking of this, Xu Feng remembered Xian Wuchen, who was killed by himself, Wang Zhishui and Nan Tianxing. If his body had not been destroyed at that time, he might have been able to extract more immortal essence, and his qi and blood power would have been greatly improved.

However, he did not think so much at that time. Shaking his head to eliminate these distracting thoughts, Xu Feng looked down at the corpse of this mysterious immortal.

"Wild God Seal, condense!"

As a hand gesture was made, a blood-red rune faintly appeared in the palms of Xu Feng's hands. Then, a wisp of golden immortal energy was slowly pulled out from the corpse that had turned gray by the power of the blood-red rune, and condensed into a similar golden bean in the palms of Xu Feng.

However, the size of this immortal essence crystal is much larger than Shangguan Qingyu's, as big as a thumb nail.

After burning the corpse, Xu Feng casually put the two golden beans into the storage pendant.

But what surprised him was that the golden bean turned into two golden streams of light the moment it touched the pendant and sank directly into the pendant!

Xu Feng hurriedly covered the pendant with his spiritual thoughts and examined it carefully.

At first glance, he found that the information about time travel in the pendant had undergone unexpected changes.

[Time rewind: one day, remaining days: four thousand nine hundred and ninety-nine, cooling time: six days and twenty hours]

"Hmm? This so-called cooling time has been shortened?"

After a moment of hesitation, Xu Feng had a vague guess.

After absorbing the two immortal crystals, the pendant must have undergone some changes, shortening the reset time of the time rewinding ability.

If we continue to hunt immortal species and collect immortal crystals, can we eventually shorten the cooling time to zero?

Xu Feng's eyes suddenly lit up. If time could be reversed without any intervals, it would definitely be an extremely powerful aid to him, making this already incredible ability even more incredible!

call.

After regaining his composure a little, Xu Feng no longer focused his attention here, but took out a small light green sword.

This sword is only one-third the length of the Qinglin Sword. It is crystal clear and has a faint shimmering light.

"laugh!"

Suddenly, a sword light suddenly shot out from the small sword and shot straight into Xu Feng's face. The sharp sword light directly pierced through the air without making any loud noise.

Just as the sword was about to hit Xu Feng, a layer of green vine armor instantly condensed in front of Xu Feng, directly blocking the sword.

After the sword light cut off dozens of green vines, it was directly consumed by the constantly regenerating green vines.

After the sword light dissipated, the small green sword dimmed and the green vine re-entered Xu Feng's body.

The sharpness of this sword is almost as good as his blue-grade fairy treasure Qinglin Sword.

"This should be that person's flying sword. It's a bargain for me."

With a loud bang, a layer of white flame ignited in Xu Feng's palm, which was the Suzaku Holy Fire.

He casually touched the dim little sword, and the little sword let out a wail. Xu Feng then wiped out the imprint of the original owner's mind left in it.

Then, he wrapped it in flames and began to refine it.

More than an hour later, Xu Feng dispersed the Vermillion Bird Holy Fire, and saw that the originally green flying sword had now transformed into a crystal sharp white sword, floating quietly in front of Xu Feng, exuding a sense of closeness as if it were a part of Xu Feng's body.

"From now on, I'll call you Danqing."

The small white sword emitted a faint sound of joy, circled gently around Xu Feng, flew into his mouth with a whoosh, and disappeared without a trace.

When he looked inside carefully, he saw a white flying sword slowly circling around the Taoist infant who was sitting cross-legged in the void and becoming more and more mysterious and solid in Xu Feng's Dantian Qi Sea.

"This item can be used as a new killer weapon. This immortal seed has given me many great gifts."

Xu Feng smiled faintly and took out something from the storage bag again.

This thing is actually a small token, engraved with the characters from the Mystical Realm: Twenty-One.
