Su Yu remained in the room and did not try to leave.

After some time, a maid walked in and dropped a chest filled with books onto the ground and coldly said, "These are the books about the Allheaven Battlefield. The madam wants you to read them all."

Su Yu nodded and hurriedly asked, "Can I know...the surname of my martial mother?"

He knew her given name, but he didn't know her surname.

The maid looked at him like she was looking at a fool. She said, "Don't you know Ye Batian?"

"..."

Su Yu was momentarily stunned before nodding blankly. Yes. He was such an idiot. Ye Hongyan. That was her full name.

After shooting Su Yu another look of disdain, the maid left. Was this fellow slow in the head? She was nearby when they spoke about Ye Batian. Since that fellow was aware of Ye Batian's relationship with the madam, why was he asking about her surname?

Su Yu tossed the matter concerning the maid out of his mind and picked up one of the books. Books introducing the Allheaven Battlefield could also be found in the academy, but evidently, the Allheaven Prefecture had a much bigger and complete collection of books.

The Allheaven Battlefield was massive. How massive? Well, it was definitely bigger than the Human Realm. It was also filled with entrances to numerous realms. At times, one could even drop through a portal into a random realm while in the middle of a walk.

If one wasn't discovered after dropping into a different realm, things wouldn't be that bad. But if one was discovered, things could turn really bad. If one was not discovered even after dropping into a different realm, one could simply treat it as a transmigration into a foreign world. The Allheaven Battlefield was filled with these random portals.

The human race mainly occupied the eastern sector of the Allheaven Battlefield. It wasn't that the entire eastern sector belonged to humanity. Rather, humanity was the local hegemon of the eastern sector.

The endless wars in the Allheaven Battlefield were not only for the sake of invading other realms. Rather, the Allheaven Battlefield itself was also filled with natural treasures, ancient ruins, ancient race inheritances, and tombs of ancient Invincibles. Too many opportunities could be found there.

Unique resources such as sunmoon profound yellow ponds where sunmoon profound yellow liquid could be found were also available in the Allheaven Battlefield. Thus, the myriad races had plenty of reasons to battle each other in the Allheaven Battlefield.

The most important region of the Allheaven Battlefield was the Sea of Stars in the central sector. There, the Luminous Domain Mansion could be found. The mansion would remain shut all the time. But every ten years, it would open, allowing those below a certain age to enter regardless of cultivation level. As long as one's bone age was young enough, one could enter.

As for the actual age requirement, for the human race, it was forty. The best option was for those around thirty-five to enter. Things might get more dangerous for those above that age. It was common knowledge that the older and stronger one was, the more dangerous the mansion would be for them. The books did not mention these so-called dangers in detail.

Humanity reigned in the eastern sector, but humanity was also not fully united. In fact, this was the same in the other sectors occupied by the divines, devils, demonic beasts, and immortals.

The thirty-six prefectures of humanity were spread all over the eastern sector, with each prefecture only in charge of its own allocated territory. Or to be precise, each prefecture was allowed to reign over a specific territory. All the treasures in that territory belonged to them, including the newly discovered minor realms.

During emergencies, Great Qin King could unify the forces of all thirty-six prefectures as the chief commander of humanity. But normally, each prefecture would battle alone.

Great Qin King. Number one expert of humanity. Leader of the War Shrine. Even Knowledge Seeking Realm's leader, Great Zhou King, needed to obey Great Qin King in wartime. As long as the bottom line of these Invincibles wasn't crossed, they would listen to him for the most part. Of course, they would no longer be as obedient if there was a risk that their benefits might be harmed.

Near the portal to the Human Realm was the main headquarters of humanity in the Allheaven Prefecture.

In truth, there were six portals connecting the Human Realm and the Allheaven Battlefield. And there was a headquarters near each portal. However, apart from the portal in the Allheaven Prefecture, the other portals were kept secret. Nevertheless, each portal was well-protected by a large number of experts and soldiers.

According to the rumors, three of them could be found in the three major oceans of the Human Realm and the final two were located in the Dual Holy Prefecture. But nobody knew if that was true.

The portal in the Allheaven Prefecture was the most commonly used portal by humanity. The forces of every single prefecture were also stationed here. The Allheaven Battlefield was filled with unknown mysteries.

This place was known as a battlefield because weird incidences might happen each time a battle broke out there.

This was the place for the geniuses of the myriad races to make a name for themselves.

This was also the final resting place for numerous geniuses of the myriad races.

One unique aspect of the Allheaven Battlefield was the fact that one would be rewarded by the heavens for killing opponents with a higher cultivation level. One would also be rewarded for reaching certain milestones, such as killing a hundred or a thousand opponents. Thus, one could benefit just by killing and doing nothing else in the Allheaven Battlefield.

"There are even benefits to killing?"

This was the first time Su Yu had ever heard about this. He frowned. No wonder the slaughter in the Allheaven Battlefield never ceased even after so many years. So one could actually benefit from it. In that case, nobody would mind more slaughter.

"Heavenly laws?"

Su Yu continued reading. According to the books, the Allheaven Battlefield might have been a training ground of the myriad races in ancient times. Thus, there was no suppressive force in the Allheaven Battlefield.

Every single race could go there and train. Of course, that was all in the past if it was true. That was why the heavenly laws would reward one for killing there. How could a training ground be a training ground if killing was prohibited?

"Killing for rewards...holy shit."

Su Yu cursed. That was so savage. But for some reason, he loved it. Of course, the books did not touch too much about the rewards. Basically, one would not be rewarded much by killing those in the same cultivation level. The greater rewards could only be earned through punching above one's level.

This was also why it was rather common for people to kill those above their levels in the Allheaven Battlefield. That was a place where punching above one's weight wasn't even something rare.

There, even incidents such as Cloudbreaches killing Mountainseas had happened before. Of course, these so-called Mountainseas were generally the weaker ones, such as those at the first or second stage. Meanwhile, Bai Tianhao's feat of killing a late-stage Mountainsea was still incredibly rare even in the Allheaven Battlefield.

It was incredibly rare but not impossible because it was very likely that it had happened before. These incidences had simply not been recorded down or spread widely.

"Since there are rewards for killing someone above one's level, this place is certainly very attractive for geniuses. The stronger the opponent, the better the reward."

Su Yu finally understood why this place was called the Allheaven Battlefield. It existed for the sake of slaughter. As for the rewards, one could get heavenly source qi, natural willpower, natural cultivation methods, natural characters, and anything else. There were all sorts of possibilities.

As for the exact number of people one needed to kill to be rewarded, there was no fixed number. Some people could be rewarded after killing one. Some might get nothing even after killing ten. The rules of that place were still quite vague. Or perhaps the exact rules had merely been kept secret by those who were aware of them.

One odd thing about the Allheaven Battlefield was the fact that geniuses could very easily stumble upon other geniuses there. They didn't even need to search for each other. One could simply step onto a random teleportation formation while out on a walk and end up in front of a different genius.

Ancient teleportation formations were scattered all over the Allheaven Battlefield. Some would send one to random minor realms while some would send one to some dangerous locations. Everything depended on one's luck.

Of course, these teleportation formations were getting rarer nowadays. It was a lot more common back then. After so many years of unceasing war, many of these ancient formations had been destroyed.

Su Yu continued going through the books at a rapid pace. Before long, he was done reading. His understanding of the Allheaven Battlefield had deepened considerably.

Every ten years, a different roster of Invincibles would be stationed to the Allheaven Battlefield while the previous roster would return. But as things had been rather chaotic lately, most of the Invincibles were remaining there. Some of them were standing guard in some minor realms while some were hiding in unknown major realms. For the most part, the whereabouts of these Invincibles would be kept secret.

The Allheaven Battlefield was also filled with elite armies. Every prefecture would have at least one elite army. Of these armies, Great Qin's Ironhawk Army, Great Xia's Martial Dragon Guard, and Great Zhou's Rampaging Tiger Guard were the strongest. Second after them were elite armies of the other prefectures such as Great Ming's Iron Cavalry, Great Jin's Battling Dragon Guard, Great Shang's Divine Elephant Guard, and so on.

Third on the tier list were the second-rate armies of the various prefectures such as the Devil Subduing Army, Heavenly Dao Army, and so on. All in all, the thirty-six prefectures had stationed over ten million soldiers in the Allheaven Battlefield.

Ninety percent of the elite armies of humanity were stationed there. As for Great Xia, they had recently withdrawn their Martial Dragon Guard, leaving only the Devil Subduing Army in the battlefield.

After going through the books, Su Yu found that the whereabouts of the Devil Subduing Army had also been kept secret. However, some of them were stationed in the main headquarters and some were stationed in a permanent army camp of theirs. The rest of the army would be out on secret missions most of the time.

"My old man is probably staying in the main headquarters. In short, he is right at the other side of the portal."

Xia Huyou was the one who had told him that his father had been called back to the main headquarters. But he still didn't have any plan on how he should meet his father yet. According to Xia Huyou, a lot of people were keeping an eye on his father. If he met his father without a good reason, he could easily incur the suspicion of others.

But first, he had to find a way to actually get into the main headquarters. He would think about what to do next when he was actually there.

After reading all the books, Su Yu suppressed the excitement in his heart and sat in meditation. This was the residence of a Sunmoon, so this place would be relatively safe for him. This was a suitable place for him to adjust his state before entering the Allheaven Battlefield.

Slowly, one character after another started spinning in his sea of willpower. During his breakthrough to the Cloudbreach Realm, a few of his characters were also on the verge of breakthrough. However, he had suppressed them.

But now, he was allowing them to go wild. Without his suppression, those characters started their advancement. All 180 of his apertures started pulling in the ambient willpower in the air. Before long, one of the characters entered the fourth tier.

It was the blood character. This was his first character, and it was also the first to reach the fourth tier. After its advancement, it looked even more shiny and translucent than before. It spun unceasingly, releasing wave after wave of blood force while numerous illusions danced around it.
