Immediately, the true yuan in Sun Cheng's body turned sharply, and the dragon vein true yuan was sandwiched with the medicinal power of the Yuan Qi Pill, as well as the power of the true flame, and gushed out wildly.

As the demon slayer knife fell, Sun Cheng's great trick also broke out.

The second form of the big day arrives, and the double sun erupts.

The two rounds of scorching sun swords shone with golden-red light, and under Sun Cheng's control, they swept out in two directions in front of him.

Suddenly, all the Soul Devouring Demon Bat that stood in front of the Scorching Sun Sword turned into a cluster of blue-white flames, which exploded in an instant. Even the demon bats that were not directly impacted by the scorching sun sword were burned by the scorching breath, unable to bear it, and burst one after another.

With just this blow, Sun Cheng instantly swept away the Soul Devouring Demon Bat within five meters in front of him, and thousands of them died.

In terms of the efficiency of the use of Zhenyuan, the effect of Sun Cheng's outburst of this move is definitely much stronger than the sword rays opened by a knife.

The upper ten "manta stones" were burst out, turning into a little bit of golden light, which was absorbed by the soul of the hidden dragon in Sun Cheng's sea of consciousness.

"Hiccup"

At this moment, Sun Yuan hiccuped energetically, and felt a feeling of swelling in his soul.

Wait, there seems to be something a little unusual just now? Sun Cheng suddenly thought.

It was as if the scorching sun swept past, and many of the Soul Eater Demon Bats that were not hit were also dead.

"Are these beasts afraid of fire?"

Thinking like this, Sun Cheng hurriedly waved the torch in his hand a few times. Sure enough, seeing the torches sweeping over the place, these Soul Eater Demon Bats all dodged away in panic.

It's just that the effect doesn't seem to be as good as he imagined.

As long as these beasts are not directly burned by the flames, even if they pass by, they will not have much effect.

Sun Cheng completely understood it now.

These Soul Devouring Demon Bats live by devouring souls, and they are basically composed of the power of Yuan Yin, and what they are most afraid of is not flames, but the power of pure yang. Just as the reason why these beasts can't appear during the day is because the power of pure yang is permeated between heaven and earth, one will die when they come out.

What they are afraid of is not the flame itself, but the pure yang power released when the flame burns.

"It's a pity that when the flame burns, the pure yang power that can be released is still too little. ”

However, with such an understanding, Sun Cheng's heart was already a little relieved. Whether he can survive or not depends on working this point.

At this moment, the true yuan in his body was almost exhausted.

Taking advantage of the gap cleared by the scorching sun, Sun Cheng's figure flashed sharply and cleaned up all the dry branches within a radius of five meters.

Several sword shadows waved, and all the branches were turned into arm-sized firewood, which were piled up into a connected firewood pile, and around Sun Cheng's location, connected to the rock wall, placed in a semicircular arc with a radius of less than one meter.

While Sun Cheng was doing these things, those Soul Devouring Demon Bats were also rapidly approaching, wrapping Sun Cheng again.

As a last resort, Sun Cheng could only break out wildly again, using the first form of the Great Sun Sword Technique, and a round of scorching sun swords crushed out, but compared to just now, both quality and quantity were more than one grade worse.

It's really that the true yuan in his body has reached the point where the oil is exhausted.

Fortunately, this time, he still cleaned up all the demon bats within a radius of one meter around his body.

Then, Sun Cheng's hands shot out several true flame powers, and almost instantly, the entire firewood pile was ignited, forming a circular flame wall more than two meters high, protecting him.

After doing all this, Sun Cheng finally sat down completely paralyzed, wheezing violently in place.

He didn't even have the slightest true yuan in his body, and his spiritual power was completely restrained, if he couldn't fully contribute to this last effort, then he would really die here.

Sun Cheng sat cross-legged, and after swallowing five Yuan Qi Pills in one go, he couldn't care about anything else, closed his eyes and breathed, striving to quickly recover his true yuan.

At this time, outside the wall of fire, countless soul devouring demon bats surrounded them, densely gathered together, as if forming a black wall curtain.

Some of the near-Soul Devouring Demon Bats were even squeezed by other companions and crashed into the wall of fire. As soon as it approached, it instantly burned and turned into flying ashes.

Dozens of Soul Devouring Demon Bats disappeared like this, but a "Bat Stone" appeared because of this. Only this time, Sun Cheng's dragon soul was still in a swollen state, and it couldn't be absorbed at all, and it was directly wasted.

Some of the Soul Devouring Demon Bats flew above Sun Cheng's head, trying to pounce down from the hollow of the wall of fire.

Sun Cheng also discovered the movement of these beasts, and as soon as his mind moved, the true yuan in his body circulated in the meridians at a specific frequency.

Under the traction of this special aura, the wall of fire that burst up began to bend in midair, forming a sparse web of flames, protecting the hollow above his head.

Dozens of Soul Devouring Demon Bat that wanted to cross directly crashed into the web of flames, and they all let out a miserable scream, turning into a blue-white ball of fire and bursting away.

In this way, with this wall of flames, Sun Cheng was temporarily safe.

However, after a while, Sun Chengcheng couldn't be happier. He wasn't made of steel, and he was surrounded by a scorching wall of fire, which also caused the temperature in the small space he was in to rise sharply.

Soon it has exceeded the limit of what a normal person can bear.

It is also thanks to Sun Cheng's steely willpower, even in such an environment, he can grit his teeth and persevere, as if he doesn't care at all, he still controls the operation of the true yuan in his body, and breathes normally.

Subsequently, Sun Cheng found that the situation in front of him was not all bad, at least surrounded by the wall of flames, the surrounding fire attribute vitality was extremely active, and the dragon vein true element in his body was also derived from absorbing the true flame earth dragon vein, which was also biased by the fire attribute.

Practicing in such an environment can actually have the miraculous effect of getting twice the result with half the effort.

Half an hour passed, and Sun Cheng finally restored the true element in his body to its peak state.

And in the Sea of Consciousness, the soul of the hidden dragon has also completely digested the soul power contained in the "bat stone", and there is no longer the previous feeling of swelling. Sun Cheng could even clearly feel that his Hidden Dragon Soul had evolved a lot, and even the True Yuan had become more condensed because of this.

He wasn't too surprised, because of the cultivation of the Ancient Dragon Divine Technique, the dual cultivation of dragon and martial arts, the dragon soul and the dragon vein true yuan were originally born as one.

Sun Cheng had a faint feeling in his heart that if he absorbed enough "manta stones", he would even be able to advance to the fifth level of the Yuanwu Realm.

Before he could recover from his expectations, a sense of crisis suddenly came.

Sun Cheng didn't have time to take care of anything else, his body jumped up suddenly, and the demon slayer knife in his hand slashed out one after another, killing ten sword rays, and killing hundreds of soul-devouring demon bats, and a "bat stone" also appeared, which was directly absorbed by his hidden dragon soul.

It turned out that half an hour had passed, and as the dry wood gradually burned out, the wall of fire had become weaker, giving these beasts an opportunity to take advantage of.

As long as Sun Cheng's movements were half a beat slower just now, he was pounced on by hundreds of soul-devouring demon bats, and his soul would be eaten in an instant.
