"Look for death!"

Looking at the third-order mutant leopard that rushed over, a cold light flashed in Yang Feng's eyes, and with a light snort, the qi in his body surged, and the bronze ancient spear in his hand flashed, with a sharp edge, he stabbed straight towards the body of the third-order mutant leopard.

Bang!

In a crisp sound of metal collision, the bronze ancient spear in Yang Feng's hand, with terrifying power and sharp edge, easily pierced through the body protection shield and the fur on the body of the third-order mutant leopard, pierced its head, and blasted its head with a swallow of the qi in his body, revealing a crystal third-order crystal nucleus, leaving a headless corpse.

With a wave of his hand, Yang Feng put the third-order crystal nucleus and the headless corpse of the third-order mutant leopard into the space ring, and rode the iron ox towards the depths of Nanping Mountain.

In the following time, Yang Feng continued to walk in the depths of Nanping Mountain, releasing a huge amount of spiritual power, avoiding the first- and second-order mutant beasts, accurately finding the third-order mutant beasts, killing them mercilessly, and harvesting the corpses of the third-order crystal nuclei and third-order mutant beasts.

In the early morning of the second day, Yang Feng found a cave, sat cross-legged, took out the crystal nuclei of more than ten third-order mutant beasts obtained last night from the space ring, and casually took out a third-order crystal nucleus and swallowed it into his abdomen, and then used the Gang Qi in his body to form a Gang Qi furnace in the dantian, refining the third-order crystal nucleus and transforming it into pure Gang Qi, increasing the Gang Qi reserves in the dantian, and improving his cultivation strength.

When Yang Feng devoured all the energy in the more than ten third-order crystal nuclei, the Gang Qi reserves in his body increased greatly, breaking through the bottleneck of the First Heaven of the Gang Qi Realm, and entering the Second Heaven of the Gang Qi Realm, and his cultivation strength increased greatly.

Yang Feng, who had greatly increased his cultivation, did not hesitate or hesitate at all, immediately got up and left the cave, walked deeper into Nanping Mountain, and let go of his spiritual power to find mutant beasts above the third order.

Soon, a golden mutant lion more than one zhang tall and three zhang long, covered with golden hair, entered Yang Feng's spiritual power induction, making Yang Feng's heart move, kicking the iron bull under him, and galloping towards the place where the golden mutant lion was.

The golden mutant lion is a mutant beast in the late third-order period, and its strength is comparable to that of the peak martial artist of the human True Yuan Realm, and its combat power even exceeds that of the peak martial artist of the human True Yuan Realm, comparable to the martial artist of the human Gangqi Realm, and the iron bull is only a second-order iron-armored bull, after sensing the breath of the third-order mutant lion, he immediately became a little uneasy, and when he was a hundred meters away from the third-order mutant lion, he did not dare to continue to approach the third-order mutant lion.

Seeing this scene, Yang Feng frowned slightly, feeling that Tie Niu's cultivation strength was too poor, should he change his mount.

Roar! Roar! Roar!

While Yang Feng was thinking, the third-order mutant lion found Yang Feng and Tie Niu, and immediately let out an angry roar, the true yuan in his body surged, his body soared into the air, and he rushed straight towards the place where Yang Feng and Tie Niu were, his huge mouth opened, revealing two rows of extremely sharp teeth, and his sharp claws flashed with a cold cold light under the sunlight.

The speed of the third-order mutant lion was very fast, and in the blink of an eye, it crossed a distance of 100 meters, approaching Yang Feng's side, and its sharp claws grabbed Yang Feng's body with an incomparably sharp edge, and his mouth opened, and he bit straight at Yang Feng's head, looking like he wanted to bite Yang Feng's head to pieces.

"Look for death!"

Looking at the third-order mutant lion biting his head, Yang Feng's expression remained unchanged, he snorted lightly, the qi in his body surged, and the bronze ancient spear in his hand with a dazzling light slashed through the void like lightning, stabbing into the mouth of the third-order mutant lion, piercing through his head, killing him on the spot.

"This third-order crystal nucleus is for you to eat!"

Yang Feng dug out the crystal nucleus of the third-order mutant lion, stuffed it into the mouth of the iron bull, and with a wave of his hand, put the corpse of the third-order mutant lion into the space ring, and then instigated the gang qi in the body and instilled it into the body of the iron bull, assisting the iron bull to digest the crystal nucleus of the third-order mutant lion.

With the assistance of Yang Feng's Gang Qi, the crystal nucleus of the third-order mutant lion was digested and turned into a stream of violent energy, which dispersed into the flesh and blood cells of the Iron Bull's body and was absorbed by the Iron Bull.

"Second-Order Peak, I'm wishing you a helping hand to promote you to a third-order mutant beast!"

When the Iron Bull had absorbed the crystal nucleus of the third-order mutant lion and reached the peak of the second-order strength, Yang Feng chuckled, took out three Juyuan Dan from the spatial ring, threw them into the Iron Bull's mouth, and activated the Gang Qi to assist the Iron Bull in refining the medicinal effect of the Juyuan Pill.

Thundered! Thundered!

With a violent roar, the Iron Bull digested the medicinal effects of the three Juyuan Pills, broke through the second-order bottleneck, and was promoted to a third-order mutant beast, the rapid expansion of its body size, and the rapid change of the iron armor on its body, and finally became a third-order ironclad bull more than one zhang tall and three zhang long, and its back was covered with iron thorns.

"Not bad! Let's go! ”

Yang Feng, who was sitting on the back of Tie Niu, saw the changes in Tie Niu, and when he saw Tie Niu take the initiative to put away the iron thorns under and on his side, a faint smile flashed in his eyes, and he patted Tie Niu's head and said.

Hearing Yang Feng's words, Tie Niu immediately let out an excited cow cry, stepped out of his four hooves, and galloped deeper into Nanping Mountain.

"Third-Order Blood Python!"

Looking at the blood-colored python not far away, ten zhang long and red, Yang Feng's eyes flashed with surprise, and he muttered softly.

The blood python contained a huge amount of blood-colored energy in its body, which was a great tonic for cultivating the blood system exercises, if he could refine the third-order blood python in front of him, Yang Feng would be able to cultivate the iron-blooded battle technique to the entry level, and his combat effectiveness would be greatly increased.

However, Yang Feng was not going to use the blood python to cultivate the iron-blooded battle technique, but was going to refine the blood of the blood python, and with the help of the energy in the blood python's blood, he would refine his body, and cultivate the ancient alchemy technique obtained from the ancient palace, so that the strength of the physical body would become more powerful.

Hiss! Hiss! Hiss!

When Yang Feng turned his thoughts, the third-order blood python let out an angry roar, the blood-colored body swirled, the blood-colored snake head was raised high, swallowing the blood-colored snake letter with a fishy smell, staring closely at Yang Feng, an uninvited guest, ready to launch a fierce attack on Yang Feng at any time.

Looking at the third-order blood python that made an attack posture, Yang Feng's expression remained unchanged, the Gang Qi in his body surged, and the bronze ancient spear in his hand stabbed out, and a fierce spear shot out from it, with a terrifying Gang Qi power, stabbed towards the body of the third-order blood python.

Bang!

In a crisp metal collision sound, the tail of the third-order blood python flicked hard, and it turned into a blood-colored lightning, meeting the sharp spear stabbed by the bronze ancient spear, shattering it, turning into a little light and disappearing into nothingness.

Sou! Sou! Sou!

Immediately afterwards, I saw that as soon as the body of the third-order blood python moved, it was accompanied by a crisp sound of breaking the air, turning into a large blood-colored lightning, and rushed straight towards Yang Feng's body, its mouth opened, turning into a huge blood basin mouth, ready to swallow Yang Feng in one gulp.

"Look for death!"

Looking at the third-order blood python that grew up and bit at him, Yang Feng's expression remained unchanged, and with a light snort, the qi in his body surged, and his body was wrapped in the qi, and his body flickered, and he left the body of the iron bull, turned into an afterimage, and rushed straight towards the mouth of the third-order blood python.

Bang!

In a crisp sound of metal collision, Yang Feng, who was wrapped in Gang Qi, held a bronze ancient spear and entered the mouth of the third-order blood python, the qi in his body surged, and the bronze ancient spear was full of light, with terrifying power and sharp edge, piercing the mouth of the third-order blood python, breaking the head of the third-order blood python, and the whole person came out of the head of the third-order blood python.

Thundered! Thundered!

The third-order blood python that was pierced through its head fell weakly downward, and fell to the ground fiercely, making a violent roar, smashing several large trees, smashing dozens of rocks, and splashing a large cloud of dust.

"Give me refining!"

Looking at the corpse of the third-order blood python, as soon as Yang Feng's body moved, he fell on the corpse of the third-order blood python, and the iron-blooded battle technique was unfolded, and a powerful suction force came out of Yang Feng's body, and the blood in the body of the third-order blood python surged towards Yang Feng's body like a tide, and was refined by Yang Feng's ancient alchemy technique, transformed into pure vitality, and scattered into hundreds of limbs and flesh cells, strengthening his physical fitness and enhancing his physical strength.

Soon, the blood of the third-order blood python was absorbed and refined by Yang Feng, the crystal nucleus was dug out by Yang Feng, and the body was included in the space ring.

"The third-order mutant beasts in Nanping Mountain have been cleaned up by me, it's time to clear those fourth-order mutant beasts!"

After putting the third-order blood python into the space ring, Yang Feng's heart moved, and he rode the iron bull and galloped deeper into Nanping Mountain.

Not long after, a fourth-order black bear more than three feet tall, covered with black hair, and exuding a powerful aura entered Yang Feng's eyes.

Roar! Roar! Roar!

Seeing Yang Feng and Tie Niu, the two uninvited guests, the fourth-order black bear let out an angry roar and patted his chest hard, trying to scare Yang Feng and Tie Niu, the two uninvited guests, away.

"You go and play first!"

Looking at the fourth-order black bear not far away, Yang Feng patted Tie Niu's head, and with a command, he agitated the Gang Qi in his body, and his body was wrapped in Gang Qi, turning into an afterimage, and he went straight to the side of the Fourth-Order Black Bear.

Roar! Roar! Roar!

Seeing that Yang Feng was not only not scared away by himself, but took the initiative to attack him, the fourth-order black bear immediately roared angrily, his eyes flashed with a murderous light, and the big bear paw slapped his chest, venting the anger in his heart, and with a flash of his body, he met Yang Feng, the big bear paw, with terrifying power, slapped towards Yang Feng's body.
