Han Feng was slightly startled, and hurriedly withdrew his hand and retreated a few miles away.

"Woo......"

There was a piercing sound, and the black gas actually went out of the wall of air, shooting like a sharp arrow, and pursued it closely.

Han Feng was amazed, the spirit refining vajra technique in his body suddenly opened, and a punch blasted out, although it was not a Deception Fist, but the power of that punch was also boiling like boiling water, and in the blink of an eye, this black air arrow was shattered, and it was scattered in all directions, and after many fell to the ground, it suddenly smashed out a big pit, which was extremely terrifying.

The big pits, one by one, seemed to have been melted open, and the inside was extremely smooth, which was amazing.

Han Feng's figure retreated again, and it was not until he reached a hundred miles away that the black gas stopped attacking, retracted into the qi wall, and gradually disappeared, turning into incorporeal again.

Han Feng's face was gloomy, he didn't expect that there would be such a sharp thing here, although he didn't use all his strength in the two rounds just now, he also felt extremely difficult, if he continued to fight, I don't know if there would be anything more terrifying.

"Is this demonic energy?" Han Feng had seen him call this gas when he was fighting with the old demon Messie in the Black Forest before, and later he browsed the relevant introductions in the relevant classics, it is reported that the demonic qi is the vitality of the demon realm, which is completely different from the aura of heaven and earth in this realm, and the aura of heaven and earth is extremely domineering, much stronger than the aura of heaven and earth in this realm, which is also one of the reasons why the people of the demon clan are generally stronger in this realm.

In fact, what Han Feng didn't know was that these demonic qi were not ordinary demonic origin qi, but the purest and true demonic origin qi, even in the demon realm, it was extremely rare, otherwise how could it be so powerful.

"It seems that there is really no way to force it through the past, so I can only find another way!" Han Feng sighed, not daring to take risks, after all, no one knew what secrets were still hidden inside, if it was really a demon giant who was about to recover, wouldn't he be in danger.

But just as he was about to fly out, bursts of white light suddenly appeared from the depths of his soul sea, as bright as stars, and the remnants of the talisman appeared in an instant, swaying slightly.

Han Feng knew what it meant, and he was surprised in his heart, secretly thinking that the other party could not even want to devour the demonic qi?

He didn't want to take the risk, but he couldn't resist the repeated urging of the remnant talisman, so he had to turn around and fly straight towards the qi wall.

In a breath or two, he returned to the edge of the qi wall again, used his mana, formed a thick defense on the surface of his body, and rushed in.

"Hoo ......"

He suddenly felt a lot of pressure, and in an instant, it seemed that thousands of mountains were pressing over, making him feel that it was difficult to even breathe, and his speed decreased sharply, and under one step, it was only one or twenty zhang, and the resistance in front of him was getting bigger and bigger, and sooner or later it would be difficult to move an inch.

"Buzz ......"

Suddenly, black gas emerged in front of him, gathered into a clump, and floated over like a dark cloud, and with just a breath, he came to Han Feng, wanting to drown and kill him!

Han Feng was startled, and he was about to use his own strength to resist, but at this moment, the white light of the remnant talisman seeped out from the surface of his body, blocking this dark cloud-like demonic qi.

"Sneer......"

The two phases collided, and the demonic qi and white light stimulated a brilliant firelight, causing a large area inside the qi wall to be dyed a red color, and the temperature surged, and even the void was distorted, showing a colorful light, like a dream.

However, Han Feng didn't suffer the slightest damage, all the impact was blocked by the remnant talisman, and the white light it oozes can continue to devour those demonic qi, but its speed seems to be a little slow, and it seems that devouring the other party also requires a lot of energy.

After a long time, all these demonic qi were swallowed by the remnant talisman, and the surroundings became transparent again.

Han Feng continued to fly forward, and after a while, a large area of demonic qi attacked, but they were all blocked by the remnants one by one, and he was unscathed.

Time flies, and most of the hour passes quickly.

Han Feng was able to cross the distance of seven hundred zhang, gradually approaching the central area of this great river, and he himself no longer knew how many waves of demonic qi attacks the remnant talisman had blocked, it was simply higher than one wave.

He looked inward and found that the remnant talisman had recovered to the eighty-eighth branch, which could be regarded as a rapid progress, which showed that this demonic qi was also a great supplement for the remnant talisman.

At this time, he realized more and more that this ancestral talisman was not an ordinary thing, and it was even very likely that it was not refined by the talisman, otherwise how could it be able to devour demonic qi, and it could also use demonic qi as one of the energies to repair itself.

Just imagine, if the ancestral talisman is made by the ancestor of the talisman, logically speaking, it should only be able to devour the power of heaven and earth in this realm, and it will not be able to absorb the power of other interfaces.

He shook his head, put these distracting thoughts aside, and continued to walk forward with concentration, with the help of the remnant talisman, his pressure was greatly reduced, but he didn't fly far away, and when he was forty or fifty zhang, another wave of demonic qi attacked, and the momentum was huge, hundreds of zhang huge, as if forming a large black wave, whistling and rushing, roaring.

Seeing this, Han Feng couldn't help but feel a little scared, he couldn't deal with these demonic qi, but fortunately, the remnant talisman was powerful and blocked it again, which made him feel at ease.

While watching the remnant talisman and the demonic qi entangled, he looked around and found that there was a dead silence in all directions, only bubbles and crackling from the river below from time to time.

He tried to disperse his soul power and infiltrate into the river, but found that no matter how hard he tried, he couldn't succeed, but instead spent a lot of soul power, all of which were exploded by those bubbles, and they were annihilated, so he could only give up for the time being, not daring to do it.

After a while, the demonic energy was swept away by the remnant talisman again, and its branch gap healed further, but the speed gradually slowed down, and it was obvious that its internal resistance began to emerge.

Han Feng immediately cast a spell and flew forward, although his speed was still very slow, he was still able to move a few feet in one step, and kept rushing towards the opposite bank.

At this moment, a more majestic demonic aura emerged from the opposite side again, spreading a thousand feet wide, like a black dragon lying in front of him, blocking his way.

Han Feng was fearless and indomitable, and in an instant, he met it, and under the protection of the white light of the remnant talisman, he still did not suffer any damage.

The light of the remnant talisman became more intense, and in an instant, its ninetieth branch completely recovered, exuding more powerful power, and the speed of devouring demonic qi also increased suddenly, thus forming a good cycle, allowing its branch gap to be repaired more quickly.

Han Feng gradually felt a little bored, although the remnant charm became stronger, he could benefit in the end, but after all, it was not his real strength, and at the critical moment, he still had to rely on himself.
