Leng Ye was stunned for a moment, his eyes were full of confusion, he looked at the streamer that disappeared in place, opened his mouth, and scolded: "You master and apprentice, wait for me, see that I don't pick your skin!"

Turning his head to look at the three paths not far away, the corners of his mouth raised an evil smile, and then turned into a powerful streamer, which disappeared into the sky in an instant, but the five major killing kings walked in the direction of the healing realm with their usual steps, but their faces were full of smiles.

In the boundary space, surging with violent energy, the wind and clouds changed color, two figures flickered in it, faintly, instantly standing above the clouds, looking around with cold eyes, wearing a black robe, the outline was extremely obvious, and he looked quite delicate, looked at the front in shock, turned his head and asked, "Teacher, what are you bringing me here for?"

The wrinkled old man on the side, his expression did not change much, a murderous aura flashed in his eyes, and the corners of his mouth smiled*, and he responded: "This is the boundary space, which contains many strange things between heaven and earth, which is extremely beneficial to your cultivation!"

With a childish look on his face, he asked in shock: "This is the boundary space?" There was a kind of doubt in his tone, and his eyes looked around, vaguely containing surprise, but the entire space was filled with powerful energy, and the ground was surging with rolling volcanoes, and blazing flames erupted from the mountain pass.

"Haha......" The wrinkled old man, with a smile on his face, laughed, changed his words, and responded solemnly: "Yes, this is the boundary space, and it is full of volcanoes everywhere, as well as strange soul medicines!"

The young soul man, holding back the ecstasy in his heart, nodded, stared at the volcano in front of him, and asked, "Teacher, where should we go to cultivate now?"

"Lin Feng, if you want to cultivate here, you must have long-lasting perseverance and very human endurance!" As he spoke, he frowned, turned his head to look at Lin Feng, and asked with a smile, "Are you ready?"

The piercing eyes looked around at the undulating volcano, looked at Han Zheng's eyes beside him, the corners of his mouth raised an evil smile, shrugged his shoulders, and replied casually: "Teacher, it's been so long, you still don't know my apprentice's stamina?"

Han Zheng nodded with a smile, but he really admired this kid's perseverance and endurance, based on this alone, his future achievements will not be lower than anyone else, but the means are not cruel enough, this is also his weakness, he turned his head to stare ahead, and shouted: "Then we will start cultivating!"

As soon as the words landed, the two figures swished, turned into streamers and disappeared in place, flying in the clouds, surrounded by a strong vitality, faintly flickering, cold eyes looked down, blazing flames erupted from the crater, surging upwards like beasts, and the whole sky fell into a blazing heat.

"Right there!" Han Zheng, who was flying in the clouds, stretched out his hands and pointed ahead, a loud voice sounded quietly, Lin Feng looked in the direction of his finger, a fire flashing in the clouds, billowing black smoke, like a beast-like fireworks, kept rolling above, and the surrounding area was filled with thick gas, which made people shiver.

"Teacher, can you cultivate on such a large volcano?" Lin Feng kept staring ahead, and asked without looking back, Han Zheng smiled and nodded, and Yu Guang skimmed Lin Feng behind him, and responded: "Let's go down!" After speaking, the whole body was like a kite with a broken string, raging in the wind, and instantly stood on top of the crater.

Like beast-like fireworks, the raging tumbling up, ripples around the layers of fire shadows, but Han Zheng's feet did not step on the flames, and the violent energy surged around his body, turning into an extremely hard barrier, showing a golden yellow, raging fire, extending to the entire barrier body, like a small swimming dragon, coiling around the barrier.

Han Zheng sat cross-legged in a leap, shaking the vitality in his body, penetrating into the surrounding barriers, instantly emitting a piece of light, enveloping the entire volcano, and all the flames that rushed upwards were surrounded by clusters, and with the passage of time, the fireworks like beasts, as soon as they touched the powerful gas, they suddenly became extremely gentle, turning into small swimming dragons, escaping from all parts of the body.

"This ...... How is that possible? The teacher's strength is too strong!"

Lin Feng couldn't help but exclaim, with the strength of an ordinary soul person, if he wanted to melt the blazing flame into the essence of the vitality and refine his body, it was simply a fool's dream, and to have such a strong strength, he had to surpass the soul level of the soul to be able to easily transform into the essence of the vitality in such a blazing flame, and refine his body, at this point, he was far from enough.

"Click!" An originally extremely hard barrier cracked out spider-like traces, exploded in an instant, and the vitality that penetrated into it turned into a series of fire dragons, melting in the blazing flames, and the entire body wrapped in the flames turned into a violent streamer with a whoosh, drawing a beautiful arc in the air, and standing neatly in front of Lin Feng.

"Lin Feng, have you seen how to cultivate as a teacher, it's your turn!" Han Zheng's face was full of smiles, he turned his head to look at the crater in front of him again, looked at Lin Feng with kind eyes, and asked with a smile, his firm gaze kept staring at the surging flames, turned his head to look at Han Zheng, shrugged his shoulders, blinked his eyes, and responded: "Teacher, I promise to complete the task you gave me!"

The figure flashed, turned into a graceful arc, kept flickering, and in an instant, a black shadow was suspended above the fireworks, and violent gas was surging under his feet, his expression did not change much, and there were blazing flames all around, and the gas like a swimming dragon extended to the entire body, Lin Feng looked around, his face looked extremely solemn.

Suddenly, the gas like a swimming dragon escaped into Lin Feng's body, "Forehead ......" Lin Feng frowned slightly, his face changed greatly, and instantly shook the vitality in his body, turning into a black barrier, surrounding his body inside, "Snort!" One by one, the dragon climbed on the barrier body, but it melted with it.

A wisp of black smoke billowed up, and the barrier was like boiling water, buzzing non-stop, but Lin Feng, who was inside, his face was flushed, and the vitality in his body was like a vast sea rolling, extremely uncomfortable, and the entire tendons and veins in his body had been burned by the fireworks that had escaped just now.

Lin Feng skimmed the fireworks outside the barrier, gritted his teeth, cold sweat broke out on his forehead, his expression was extremely painful, and he muttered to himself: "There should be no problem with this barrier!" As time passed, the black barrier outside it boiled in an instant, and wisps of black smoke kept rising upward, filling the entire sky.

A ball of fireworks rushed inward, from the esophagus and poured into the muscles and veins in the body, only a few snorts were heard, a wisp of white smoke billowed up, and a closer look at it, countless small black bubbles emerged from the entire tendons, which were permeated with the gas of the hydra, which was terrifying.
