C249 Ancient vicious beasts

The five people's residences were all connected together. After exchanging greetings, they all entered their respective residences.

This room was extremely small, but it was sufficient for cultivation.

With a wave of his hand, Gu Xuan summoned the Ice Soul Cold Flame out of his body and said: "Yun Xi, now you should feel the Elemental Energy of Heaven And Earth here, what rank is it?"

"Alright!" Yun Xi replied as a devouring force came out from within the flames, slowly devouring the surrounding Elemental Energy of Heaven And Earth.

At the same time, Gu Xuan also felt a wave of pure Strength of Fire entering his body.

"Alright!" Gu Xuan raised his eyebrows, his face revealing a happy look, from the Strength of Fire, he could feel that refining the Elemental Energy of Heaven And Earth had brought about an increase in his cultivation realm.

It was almost the same as when he first refined the Ice Crystal Cold Marrow.

"My Earth Rank is low. I can absorb fifty percent of this power. Cultivating here is probably equivalent to refining ice crystal Cold Marrow all the time." Yun Xi stopped her refinement and exclaimed.

"If that's the case, then the effect will be even greater than when I refine the ice crystal Cold Marrow." Gu Xuan laughed.

There were still many considerations when refining the ice crystal Cold Marrow, such as the price of the ice crystal Cold Marrow and the efficiency of the ice crystal Cold Marrow.

Therefore, Gu Xuan only refined a single pill every day, and he had purposely slowed down his refining speed in order to achieve the greatest efficiency.

But right now, within the Flame Devil Ancient Mansion, these Elemental Energy of Heaven And Earth were an inexhaustible supply, so naturally, they could increase their rate of absorption the most.

Hu hu!

Yun Xi began to devour with all her strength, attracted all the surrounding Elemental Energy of Heaven And Earth, and it practically formed a gale as well, forming a whirlpool. With Yun Xi as the center, it began to devour crazily.

Without considering the cost, Gu Xuan's cultivation speed had even surpassed the number of hours he had spent on refining the ice crystal Cold Marrow.

Although the Elemental Energy of Heaven And Earth s were not as effective as Gu Xuan and the other three, it was still no small matter. Thus, other than occasionally gathering together, the five of them were frantically devouring the energy of heaven and earth.

Of course, this situation wouldn't last long, as the price for entering the Flame Devil Ancient Mansion was just too high. Just activating the Transfer Array alone would consume a total of ten million Spiritual Crystal and then bring them into the city to protect.

With these Spiritual Crystal, he could completely buy treasures that were even more important than these Elemental Energy of Heaven And Earth. Furthermore, under the temptation of these treasures, it was enough to make people take the risk.

Gu Xuan, on the other hand, became someone who cared the least about treasures. With this Elemental Energy of Heaven And Earth, it was already considered a pretty good treasure for him.

However, Gu Xuan's cultivation was interrupted after the third day.

At night, outside Falling Cloud City, there were waves of beast roars that were sharp and ear-piercing. Countless Vicious Beast were running around, causing the ground to tremble.

"All Martial Cultivator from Fallen Cloud City, quickly come out and defend against the Vicious Beast!" Within Fallen Cloud City, a shout resounded. A few Martial Cultivator s also quickly came out of their residences and leaped towards the city walls.

When Gu Xuan walked out, he realized that Xue Feng, Liu Ying and the other two were already waiting outside, it was just that Gu Cheng was missing, but Gu Xuan did not have the right path with him, so he did not care.

"Junior Brother Gu Xuan, although fighting with Vicious Beast is not dangerous, about half of us will die. The four of us will try our best to stand together and take care of each other." Xue Feng said solemnly.

"Alright." Gu Xuan agreed as he rushed to the top of the city, with Xue Feng and the other two following closely behind him.

Looking down from Fallen Cloud City, he saw a dense mass of strange black beasts. This beast was half the size of a house, its entire body was covered with bone spikes, but its speed was extremely fast. Just the impact from its body was enough to cause the death of an ordinary middle stage Sovereign Level Martial Cultivator, it could even be said to be a mortal weapon!

Xiu Xiu! *

When the Vicious Beast approached Falling Cloud City, it gradually jumped up. A city wall that was over a hundred feet tall did not hold much meaning for a battle of this level.

However, the Martial Cultivator on top of the city walls were mostly in the late stage of Sovereign Level, so killing these Vicious Beast wasn't a difficult task.

"Roar!"

Finally, a Vicious Beast rushed straight in Gu Xuan's direction and jumped onto the city wall.

"Is this the Ancient Vicious Beast?" Gu Xuan had carefully given a large number of Vicious Beast s at a close distance. This kind of thing was something that he would only hear about in legends, but he never would have thought that he would have the chance to see it again.

The Burning Heaven Continent was truly too vast. Unless one was an old monster that had lived for thousands of years, basically, no one could travel across the continent.

Seeing how Gu Xuan was looking down on him, the Vicious Beast's scarlet eyes flashed with anger as it crazily rushed towards Gu Xuan.

"Freeze." Gu Xuan bellowed, and from his body, a burst of cold Qi swept out, rolled into a Sword Qi, and burst out.

Puff!

The Vicious Beast's leather armour was easily torn apart like thin paper by Gu Xuan's Ice Cold Sword and heavily fell to the ground.

"This is?" Gu Xuan's Ice Qi struck into the Vicious Beast's body, but it felt as if there were something abnormal inside the Vicious Beast's body.

The Ice slashed fiercely, causing the Vicious Beast to split apart, revealing a blue crystal in its stomach, and then used the Ice Sword Qi to wrap it up and return it to Gu Xuan.

"This is …"

Looking at this blue crystal, Gu Xuan had a puzzled look in his eyes. He seemed to feel that this blue crystal seemed to hold some attraction for him.

"Junior Brother Gu Xuan, this crystal is called a beast core. It is similar to the Animal Crystal and is the most important part of the Vicious Beast's body." Xue Feng who was at the side saw Gu Xuan's puzzlement and reminded him with a smile.

"Oh?" Gu Xuan raised his eyebrows, and then placed the beast core down without batting an eyelid.

The primordial origin energy was of such high quality that it was enough to reach the Earth Rank. This primordial beast core was formed from primordial origin energy, how could it be weak?

"Yun Xi, devour the beast core. Let's see what rank it is." Gu Xuan ordered Yun Xi.

"Understood." Yun Xi entered Gu Xuan's palm and wrapped the Animal Crystal up.

A moment later, a majestic Strength of Fire poured into his Dantian from his palm. Gu Xuan could clearly feel that his realm had increased by a sliver.

Just this tiny bit of it was comparable to the fifteen minutes of training he had gone through.

"Gu Xuan, this beast core's grade isn't high, it's only a high grade Profound Rank monster, but the Elemental Energy of Heaven And Earth inside are very easy to refine. Although it can only absorb forty percent, if one can obtain more, their cultivation speed would not necessarily be lower than a Heaven Rank treasure."

Yun Xi said in pleasant surprise.

"Very good!" Gu Xuan's eyes revealed an excited light. No matter if the beast core was of such grade, to be able to quickly raise it, he could truly feel it.

And with so many Vicious Beast below the city walls, there would be an endless source of beast cores to obtain.

"Now, let's begin the slaughter." Gu Xuan's eyes flashed with a sharp glint.
