The moonlight was like a hook as stars filled the sky.

At the summit of the back mountain of the Immortal Yang Spiritual Academy, Cang Yun was lying on the grass with his hands behind his head and his eyes closed. Feeling the cool breeze blowing on the mountain, he felt relaxed and at ease.

He often came to this place, especially during the past two years when he had lost his cultivation. Whenever he felt displeased or had to think about things, he would always come here and always get an answer.

"The Netherworld …" Thinking of the news Xu Guang had brought, Cang Yun pursed his lips and sank into deep thought.

The continent of the Nine Provinces was extremely vast and it was formed by the nine continents. The Azure Province was one of the nine continents.

The Azure Province was further divided into the one hundred and eight Ancient Realms and the Thirteen Spiritual Academies. Cang Yun was born in the one hundred and eight Ancient Realms, and his father was the current master of this realm, the master of this realm. He commanded the entire Vastheaven Realm, and from the moment he was born, Cang Yun's fate had been closely linked with the Vastheaven Realm.

It could be said that the two great ancient realms had always been at odds with each other since ancient times. Moreover, over time, the conflict between the two realms became more and more acute, and after Cang Yun's father had become the ruler of the Vastheaven Realm, this conflict had accumulated to an unprecedented degree. Both sides knew in their hearts that a war was already unavoidable.

One month later in the Immortal Yang Secret Realm, the young disciples of the two realms would declare war. This was just the beginning of a great war, but there was no doubt that the victorious side would gain some advantage in the upcoming battles. In addition to the special nature of the Immortal Yang Secret Realm, there was no reason for either side to retreat.

Ever since Cang Yun's cultivation had been crippled two years ago, in terms of young disciple's strength and talent, the Azure Sky had always been weaker than You Luo. And now, with Xu Guang, the person who was ranked first in the Earth Class, the overall strength of the Nether Realm had increased by quite a bit.

If nothing unexpected happened, then Vastheaven Realm had almost no chance of winning this battle, and the outcome of the losing side was destined to be very bad. After all, this was a war, and there was no benevolence in the war.

As he thought of all this, Cang Yun opened his eyes and sat up in a reclining position. The satisfied look on his face slowly disappeared, and was replaced with a resolute and serious expression.

"As the Young Master of the Vastheaven Realm, I definitely won't allow that to happen."

A soft mumble sounded out, and in the next moment, Cang Yun sat cross-legged with both of his eyes closed. He slowly raised both of his hands and began to form mysterious seals in front of his chest.

Weng! *

In an instant, the Heaven and Earth powers seemed to be pulled as they quickly gathered around Cang Yun's body. They drilled into his skin, followed his meridians, and finally gathered in his Dantian where a thumb-sized, blood-colored crystal that was about to take shape was emitting a resplendent light. It was like a vortex, greedily absorbing the energy that had entered his Dantian.

Following this absorption, some of the initially incomplete blood-colored crystals were rapidly agglomerating. Moreover, a powerful and strange fluctuation was being emitted from within them. It was as though something extraordinary was quietly awakening.

He had condensed a blood source!

If this scene was seen by anyone else, it would definitely cause a huge commotion, because everyone knew that Cang Yun's blood source had already been completely destroyed two years ago, and it was impossible for the blood source to be reformed once it was crippled. This was an iron-clad rule, and no one had ever broken it before, but looking at the situation Cang Yun was in now, he seemed to have created this miracle, which had completely overturned everyone's understanding.

However, Cang Yun's expression did not change at all, and there was no excitement or surprise on his face. He seemed to take everything that had happened for granted.

And this was indeed the case. Two years ago, very few people knew the truth behind everything that had happened in the 'Blood realm', so people's guesses were not entirely accurate.

It was not that he did not complete the trial. In fact, in the end, he managed to come into contact with the legendary Blood Stele, and it was only at that time that he was secretly harmed, resulting in the crippled of the peerless blood source in his body.

However, it could have been a coincidence. The moment he was kicked out of the Blood Stele, something quietly escaped from it and rushed into his body.

It looked very similar to a martial artist's blood source, but its surface was dull and gloomy, as if it had suffered some kind of trauma, and had lost its original luster. However, the fluctuations contained in it were very shocking, and even though it only exposed a little bit, it was like a sting lurking in the silent clouds, with the power to tear apart the heaven and earth.

After the blood crystal had entered Cang Yun's body, it immediately occupied the spot where the Blood Origin was in his dantian. Moreover, it released a strange suction force that actually absorbed all of the broken and dissipating power of the Blood Origin. As a result, the blood crystal had recovered a bit and gained a bit of luster. It slowly fused with the body, replacing the crippled Peerless Blood Origin from before and becoming a new source of blood for Cang Yun.

This situation was extremely strange, but it could not be said to be unprecedented in the history. In the distant era, when the super strong warriors of the continent did not have much life left, they would try their best to take away the blood source in their bodies, leaving behind the inheritance so that the fated descendants could obtain it. Cang Yun's situation was very consistent with the rumors, so he guessed that the blood tablet of the Blood World was actually the inheritance of a super strong expert from ancient times.

However, Cang Yun also understood the principle that possession of a treasure was a crime. Hence, he did not announce this matter to the public after he came out of the 'Blood World'. Instead, he silently admitted to the sarcastic rumors of the people, and patiently trained, waiting for the day that the blood source would recover.

After two years of hard work, this day had finally arrived.

At this moment, the crimson blood source within his dantian had already recovered its luster. The original cracks had completely disappeared, reforming into a complete crimson crystal. On its surface was a dense seven colored glow. It was noble and sacred!

At this moment, the originally clear night sky was covered by dark clouds. Thunder rumbled within the dark night sky; it sounded like anger and panic.

Cang Yun was jolted awake by the thunder and retreated from his cultivation. He stood up and looked up and down through the gaps between the trees in the mountain towards the Immortal Yang Spiritual Academy, which was lit up by the lights.

"Two years, I, Cang Yun, have returned!"
