Cangzhou City, as the third city of Yuanyou County, has a population of more than six million, and the officials of Yuanyou County have arranged several large arrays here.

In addition, Fengling Academy once set up a branch here, and also sent several array mages here to consolidate the city protection array.

Now Cangzhou City's protective array can even easily resist the attacks of the Xuantian Realm powerhouses.

"Boom ......"

A huge fireball landed on the protective light curtain above Cangzhou City, and the entire Cangzhou City was shaken.

"What's going on? Could it be that someone is attacking Cangzhou City?"

"Impossible, although Yuanyou County is only a five-star county, the weakest among the seven kingdoms of Yunling, but the seven major counties have all signed the peace treaty under the mediation of Fengling Academy, whoever dares to start a war is against Fengling Academy, no one in the entire Yunhuang has such courage to dare to challenge the majesty of Fengling Academy!"

At this moment, the city was already in chaos, and many civilians were messing around in the city.

The rolling lead clouds soon enveloped the entire Cangzhou City, like the end of the world, and the fireballs in the sky were as dense as raindrops, as strong as Cangzhou City, still giving people a sense of wind and rain.

......

The vast mountain range is also in chaos at this moment, and the fierce birds and beasts seem to be crazy, running out desperately, and a large-scale beast tide has been formed.

Xiao Han dragged his tired body, not only to avoid the crazy fierce birds and beasts, but also to guard against the fireballs falling from the sky, which could be described as difficult.

A huge fireball landed on a hill three or four hundred meters high behind Xiao Han, directly leveling the mountain.

"No, if this continues, I will definitely die!"

The lead cloud had enveloped the entire vast mountain range, and everywhere there were fireballs, and everywhere there were the roars of ferocious beasts.

Xiao Han never expected that a third-level earth fire array arranged by him would cause a monstrous disaster.

"I, Xiao Han, am smart, do I have to explain it in my own hands today?"

The entire vast mountain range has turned into purgatory on earth, fireballs fall, fierce beasts are raging, and the demonic beasts that are usually hidden in the shadows and are rare to see also appear frequently at this moment.

Suddenly, Xiao Han's eyes lit up, as if he had thought of something, but he quickly frowned again, revealing an expression that was difficult to decide.

"That's it, I've come this far, I have no choice but to gamble!"

Xiao Han took out the dragon's eye-sized magic core, gritted his teeth, and took it down with his eyes closed.

Suddenly, a hot sensation came from Xiao Han's abdomen, and this feeling became more and more intense, as if it was about to burn his abdomen.

"Incarnate the sky, derive the ...... of the world"

Xiao Han desperately ran the "Great Heaven Derivative Sutra".

The energy in the demon core is huge and violent, and humans can't absorb it directly, even if a Xuantian Realm martial artist directly takes it, it will explode and die.

Xiao Han dared to do this, and he had also seen in some wild histories that in the extremely glorious era of the Apocalypse, some people who cultivated the anti-heaven exercises could directly swallow the demon core and absorb the violent energy in the demon core.

At one time, he would certainly not believe such a rootless history.

You must know that he used to practice the Heavenly Emperor Emperor's "Heavenly Emperor Decision", and the degree of anti-heaven was not weaker than any anti-heaven exercise in history, but he still didn't dare to directly devour the demon core.

But things have developed to this point, and Xiao Han has no choice but to let go and make a last stand.

As if swallowing a ball of flame, Xiao Han felt that his whole body was being scorched by the flames.

At the same time as the pain, he also found that the demon core was releasing energy, and after the refining of the Great Heaven Derivation Sutra, it was no longer so violent.

Soon, his dantian was filled with energy again, and his wounds were healing at a speed visible to the naked eye.

Everything seemed to be developing in a good direction, but Xiao Han felt a little creepy.

The demon core cracked open in his abdomen, revealing a tiny crack, and endless energy was released from this tiny crack, completely uncontrolled.

Xiao Han noticed this, and his face changed greatly.

"If this continues, won't I be blown up in the dantian and eventually explode to death!"

He didn't dare to hesitate, he exerted his Yunyan step to the extreme, and ran towards the outside of the vast mountain range almost overloaded.

In more than thirty seconds, he had completed more than a hundred footprints, reaching four or five miles away, and so on, he turned into an afterimage in the jungle, even some high-level fierce beasts that were good at running, it was difficult to match.

Spirit-level martial arts are very consuming of Xuan Qi, if it is usual, even if he has a top-level technique as a cornerstone, seven or eight minutes is enough to consume the Xuan Qi in his body.

But now, he can completely ignore the issue of consumption.

The energy of the demon core of the first-order peak demonic beast was so huge, as soon as he consumed a little bit of the Xuan Qi in the dantian, the demon core immediately released energy to replenish it.

"No, the speed at which the demon core releases energy is too fast, even if I overload the Yunyan Step, the consumption is less than one-tenth of what I replenish, and if this continues, I will still be bursting the dantian. ”

Xiao Han had turned into a 'fire man', and the energy overflowing from his body had completely 'ignited' him.

"The cracks of the demon core are getting bigger and bigger, and the speed of releasing energy is getting faster and faster, even if I consume it quickly, it can be replenished in an instant, and it will expand, and it may explode and die at any time. ”

"Taixuan Sword Finger!"

Xiao Han seemed to be crazy, running two spirit-level martial arts at the same time.

In the jungle, I saw an afterimage floating, and all the surrounding flowers and trees were cut off, and many fierce beasts died tragically under this afterimage before they could react.

Xiao Han's speed is getting faster and faster, but he still can't extinguish the 'fire' on his body.

Time passed little by little, Xiao Han had already been 'burned' his mind, his body did not obey the call, his vision became more and more blurred, and he couldn't see the road at all.

"Plop ......"

It seems that he rushed into a lake, and Xiao Han gradually lost consciousness!

......

I don't know how long it took, when Xiao Han woke up again, he found himself lying by the river.

"Crescent River Valley!"

Xiao Han had been here before, and it was only more than three hundred miles away from Cangzhou City.

At this moment, the forests on both sides of the river have been burned down, and there are still a few sparks burning at the roots of some carbon wood, and the lead clouds in the sky are not as thick as they used to be, but they still give people a feeling of being overwhelmed.

The temperature of the river reached almost seventy or eighty degrees Celsius, and there were still many unburned scorched trees floating on the surface of the river, as well as the corpses of some unknown fierce beasts.

"I'm still alive!"

Xiao Han got up with difficulty and sat cross-legged on the shore, breathing with luck.

"Hey, my dantian... It's ten times bigger!"

Xiao Han was shocked, and immediately closed his eyes to check, and found that there was an extra spiritual vein under his left and right armpits!

Xiao Han was pleasantly surprised, but he didn't expect that this time he would risk his death to swallow the demon core, and he would actually break through two small realms in a row and directly reach the Nine Heavens of Xuanqi.

While being pleasantly surprised, he also knew very well how much risk he had taken by swallowing the demon core this time, and that he was able to survive this time, but luck accounted for more than half of it.

Until this time, he was still a little scared in his heart.

"Don't swallow the Demon Core in the future!"

......

Three hours later, Xiao Han finally finished pranayama and restored himself to an unprecedented peak state.

"With such a big disaster, I don't know what happened to Cangzhou City. ”

Although Xiao Han knew that Cangzhou had a big city protection array, it shouldn't be a big problem, but he still couldn't let go of it in his heart, and immediately set foot on the road home.

It was as if there was a cloud of smoke under his feet, falling on the soot, and not even a single footprint was left.

Now Xiao Han has become more and more proficient in Yunyan Steps, and he can step out one hundred and fifty footprints at a time, and after running a complete set of martial arts, he can almost reach six or seven miles away.

His speed became faster and faster, and he ran a distance of more than 300 miles in ten minutes.
