"Is there any hope of recovery?" Hark looked at Gu Yu with a hint of regret in his eyes. They came for the genius, but if this genius is ruined, wouldn't it be a waste of their time? Who would want a ruined genius? Hark, at such a young age, is already at the mid-stage of the Commander Realm, no, at the peak of the Commander Realm. Someone like that, perhaps given another fifty years, might be able to reach the Emperor Realm, or even a hundred years would be fine. The Emperor Realm is the pillar of the royal family. The royal family doesn't lack King Realm members; even a declining royal family has King Realm members. But the royal family lacks Emperor Realm members.

Hearing Hark's words, Gu Yu was extremely excited. This was simply a great joy. Not only had his identity not been exposed, but it had become even more secure, which would greatly benefit his future plans. Fortunately, he hadn't attacked Hei San when he learned of the Hark family's arrival, or he would have been finished. Indeed, there's always a way out! After all, there's always a way out!

"Although the side effect of my secret technique is the loss of cultivation, it can also be recovered. It requires an extremely large amount of source energy, preferably from high-grade source stone mines. Moreover, it would be even better if some rare and precious materials were used as aids," Gu Yu said.

"That's good." After hearing Gu Yu's words, Hake's regretful expression instantly improved. It was good that he could recover; otherwise, her Ha family would have lost a genius, not a future Emperor Realm expert.

In recent years, although the Ha family has been able to maintain its second position thanks to Ha Daohuang, it has had very few members at the Emperor level, only three. In contrast, the Barbarian family has as many as six members, plus a demigod ancestor.

"Damn, he really is a member of the Ha family!" Hei San was shocked. "Oh my god! He won't retaliate against me, will he? His attitude towards him just now was not good."

"Brother Hark, is he really the genius of your Hark family?" Black Wind Whirlwind asked with a frown. For some reason, he felt something was wrong. He knew that Hark did not know Gu Yu.

"Ha Yu, do you know the Ha family's Heaven-Slaying Blade?" Hark asked, frowning as he looked at Gu Yu after hearing Hei Fengxuan's words.

The Heaven-Slaying Blade is the ultimate technique of the Ha family. Almost everyone in both the main and branch branches of the Ha family has learned it, but it is absolutely forbidden to pass it on to outsiders. Anyone who does so will be killed without mercy.

As a genius of the Ha family, Ha Yu definitely can.

"Of course I will," Gu Yu replied. The Heaven-Slaying Blade—speaking of which, his creation of the world was the Heaven-Slaying Blade. Gu Yu remembered that the first time he fought against Ha Daohuang, he was defeated by the Heaven-Slaying Blade. That one strike almost took his life.

After escaping, Gu Yu later killed a genius from the Ha family and obtained the Heaven-Slaying Blade from him through special means. After countless practices and improvements, he created the Heaven-Opening Blade, which is the Heaven-Slaying Blade.

"Oh? Show me how you do it," Hark said immediately upon hearing that Gu Yu could do it.

“Um…” Gu Yu scratched his head, “My knife is broken, could you give me a new one?”

His sword is a wooden sword, given to him by the Tree of Life. If he were to take it out, it might arouse suspicion. After all, he needs to be careful. What if someone asks him where the wooden sword came from? How would he answer?

It's important to know that the wooden sword is of a high grade, and its material is the hardest trunk of the Tree of Life. Although ordinary people may not recognize it, these are all powerful members of the Minotaur race, and it's not impossible that someone with sharp eyes might recognize it.

“Okay.” A long sword immediately appeared in Hack’s hand, and he handed it directly to Gu Yu.

Gu Yu took the longsword, gripped it, and thought, "This sword is good; it must be Hack's weapon."

“Come on, use the Heaven-Slaying Blade to cut me,” Hack said to Gu Yu.

Although the Heaven-Slaying Blade is extremely powerful, very few people in the Ha family have successfully mastered it. Even though Gu Yu did master it, he couldn't even hurt Hake, who is a quasi-emperor!

"Senior Hark, be careful." After Gu Yu finished speaking, his aura suddenly surged. Although his cultivation was only at the second level, he used the power of gods and demons to perform the One Qi Transformation Technique. Therefore, when he used the Heaven-Slaying Blade, he was using the power of gods and demons.

With the combat power of a peak-level five-cone, plus the Heaven-Slaying Blade, he can barely reach the realm of a general.

Sensing the sudden burst of power emanating from Gu Yu, Hack's expression changed, as did the others.

Gu Yu's cultivation level was only at the second level, yet he unleashed the power of a peak fifth level cultivator. It seems that his cultivation level was indeed damaged due to the use of a secret technique.

"Heaven-Slaying Blade!" Gu Yu suddenly slashed down with his blade, the indestructible blade energy aimed at Hake. Hake casually waved his hand, and the originally indestructible blade energy was like tofu in front of him, instantly annihilated with overwhelming force.

"Your Highness Ha Yu." At this moment, Ha Ke bowed directly to Gu Yu and called out. Ha Yu was the future adopted son of Emperor Ha Yue, the adopted son of the Emperor Realm. His status and position were far higher than Ha Ke's. Although Ha Ke was a quasi-emperor, only one step away from the Emperor Realm, he knew very well that he could never step into the Emperor Realm. His talent limited him, and there was nothing he could do about it.

Black Wind Whirlwind and Black Three's expressions changed. Although they had never seen the Heaven-Slaying Blade, they were certain that Ha Ke could not be mistaken. They had not expected that Gu Yu was really a member of the Ha family.

Gu Yu was incredibly excited. It was truly heaven's help. If he hadn't possessed the ability to open the heavens, this battle technique, which was an improvement on the Heaven-Slaying Blade, would probably still be suspected today. It was such a coincidence that Gu Yu himself could hardly believe it.

"Alas! It's a pity my cultivation has been severely damaged," Gu Yu sighed, shaking his head.

"Your Highness Ha Yu, has your Heaven-Slaying Blade reached its full potential?" Hake asked respectfully.

"Mm!" Gu Yu nodded.

"Your Highness Ha Yu, you are a genius!" Black Wind Whirlwind suddenly said at this moment.

“Yes, Your Highness Ha Yu.” Hei San immediately chimed in, “Brother Ha Yu, our Hei family has high-grade source stone mines that can restore your cultivation. Our Hei family also has many rare and precious materials that you can choose from.”

Having confirmed Gu Yu's identity, Hei San was determined not to miss the opportunity to befriend him. As he spoke, the peak-level Shuai Jing who had been silently watching everything frowned. He was none other than Hei Yi, the current crown prince of the Black Bull Kingdom.

“Your Highness Ha Yu, my brother is right. I will open the Hei family’s treasury in a moment. You will be free to choose any treasures inside.” Hei Yi said at this moment. Hei San wanted to win over Gu Yu, and so did he.

His father, Black Wind Whirlwind, is getting closer and closer to the Emperor Realm. It's believed that he will soon go into seclusion, at which point a new Black Bull King will appear. Although he is the Crown Prince, he has quite a few supporters, especially Ha Yu, the adopted son of Emperor Ha Yue. Gaining Ha Yu's support is equivalent to gaining Emperor Ha Yue's support in disguise—an Emperor Realm expert! Especially the Emperor Ha Yue from the Ha family. You must know that although Emperor Ha Yue is the weakest among the three Emperor Realm experts in the Ha family, he is still a late-stage Emperor Realm expert, even stronger than the late-stage Emperor Realm expert from the Black family.

"Treasure Vault?" Gu Yu frowned, his gaze turning to Hark. He was now filled with even more worry, fearing that Hark would take him back to the Hark family immediately, in which case his plan would still fail.

“Your Highness Ha Yu, if you wish to recover your cultivation before returning to the Ha family, that is also possible,” Ha Ke said, seeing Gu Yu looking at him.

The Ha family doesn't have any high-grade Originium mines. The high-grade Originium mines of the Barbarian Kingdom have always been controlled by the Barbarians. The Ha family can only get a small share of high-grade Originium each year. Now that the Black family is willing, it's perfect.

"Really?" Gu Yu's face lit up with joy; this was exactly what he wanted.

“Your Highness Ha Yu, this old servant is only responsible for Your Highness’s safety. There are some matters that must be decided by Your Highness,” Hake said, bowing.

The Ha family places great importance on geniuses. In recent years, the Ha family has not produced any new Emperor Realm experts, which is a very serious problem for the Ha family, as it is a sign of decline. If it weren't for the prestige of Ha Daohuang, the Ha family would actually be inferior to the Hei family.

When the Ha family heard that Ha Yu had gone missing in Niuhua City, they were extremely anxious. They knew that if anything happened to Ha Yu, their Ha family would lose someone who could potentially become a royal in the future.

"Can I go into the treasure vault and take a look?" At this moment, Gu Yu was already drooling over the Hei family's treasure vault. A treasure vault in a royal city must contain countless rare and precious treasures.

"Your Highness, I'll lead the way right away," Hei Yi said immediately, which made Hei San's expression turn ugly.

“Brother Ha Yu, I’ll lead the way for you too, we’re brothers!” Hei San hurriedly added.

"Okay." Gu Yu nodded.

Black One and Black Three immediately stepped forward to lead the way, while Black Whirlwind and Hack followed behind them.

"Your Majesty, I've heard that the Seven Kings' Allied Forces will arrive at Niuhua City soon. How confident are you this time?" Hark asked Black Wind Whirlwind on the way, while Gu Yu also pricked up his ears to listen.

"I'm very confident. With the support of that lord from the Barbarian Kingdom, it's no problem," Black Wind Whirlwind said.

“Alas! Of the six kingdoms, three do not support war with humanity,” Hark said.

"What does the Ha family mean?" Black Wind Whirlwind asked Hack.

“The Ha family also does not support this,” Hark said. “Humans have a true god. Even if the other side is restrained by someone, if we really push humanity to the brink, no, we should say push that true god to the brink. If he fights to the death, my Minotaur race will face annihilation.”

“Actually, we don’t want to fight either, but this is the barbarian’s order, and we cannot disobey it. Moreover, my Black Bull Kingdom does need to take back Niuhua City,” Black Wind Whirlwind said.

“Alas! What is meant to be will be.” Hark said meaningfully, “Our Hark family believes that humans are not so simple, and it is very likely that there are even demigods among them.”

"The existence of a demigod?" Black Whirlwind's expression changed.

“Very likely,” Hark said.

"Where did you get that conclusion from?" Black Wind Whirlwind asked.

"It's just a feeling. According to the data and documents, some humans on Earth have even reached the Ancestral Realm," Hack continued.

"Brother Ha Yu, the treasure trove of my Ha family lies just ahead," Hei San said to Gu Yu.

Ahead was an artificial mountain. Ordinary people could not see anything around it, and even Gu Yu could not sense anything. However, if one were a King Realm expert, one could sense a faint layer of restriction around the artificial mountain.

Black Wind Whirlwind stepped forward, a token appearing in his hand. The token flew towards the artificial hill, instantly opening a passage.

As the passage opened, streams of energy emanated from it.

After walking about seven or eight meters into the passage, the view suddenly opened up.

Countless cabinets and boxes made of high-grade wood were displayed before them, along with a large quantity of high-grade source stones, rare and precious materials, weapons, and all sorts of other rare treasures.

The treasure vault was about 100 square meters in size, filled with a dazzling array of items, wafting with wonderful fragrances, and brimming with all sorts of energy.

This is the Black Bull Kingdom's savings accumulated over many years. Only treasures are worthy of being placed here. If you add up all the treasures here in Chinese currency, they could probably buy half of China.

“Condensing Cone Flower, Heaven-Reaching Fruit… This is Black Gold Refined Gold.” Gu Yu’s pupils widened as he looked at the dazzling array of treasures. Even Hark was shocked to see so many treasures.

Although the Ha family is stronger than the Hei family, the Ha family's treasures may not be as numerous as the Hei family's. It seems that the Hei family has really gone to great lengths to win over Ha Yu, or rather, the Ha family. They have such a treasure trove, yet they are completely unprepared for them.

If he hadn't known that the royal city had a royal domain, Hack would have already tried to rob it.

"The Black Bull Kingdom is a small place. These treasures are the accumulated wealth of my Black Bull Kingdom over the past few hundred years. They can be said to be all the savings of my Black Bull Kingdom," Black Wind Whirlwind said, seeing the surprised expressions on Hake's and Gu Yu's faces.

As long as the treasure can tempt Hack and Gu Yu, that's fine. Once they are tempted, there will be opportunities to befriend and win them over.

"Your Highness Ha Yu, you can choose ten treasures from here. Anything that is beneficial to your cultivation recovery can be taken," Hei Fengxuan said, looking at Gu Yu who was practically obsessed with the treasures.

"By the way, Brother Hack, you can also choose three treasures." Black Wind Whirlwind looked at Hack, a peak King Realm expert whose combat power had reached the level of a Quasi-Emperor, and was also someone worth befriending.

"Your Majesty, then I won't stand on ceremony." Upon hearing Black Wind Whirlwind's words, Hark's face lit up with joy. He had indeed taken a liking to a few treasures. Besides, even if he didn't find any he liked, who wouldn't want treasures? As for the issue of being indebted to others, was that even a problem? It was all for the future; why think so much about it?

“I want this black gold refined gold,” Gu Yu said, pointing to a piece of black iron that emitted a dark, luminous glow.

Black gold is the size of two basketballs. This metal is extremely rare and is used to forge divine artifacts.

"Black gold refined gold?" Hark's face stiffened when he saw the metal Gu Yu was pointing at. Actually, he had also taken a liking to this thing. To be honest, his sword wasn't very powerful. If he were to forge a sword using black gold refined gold and engrave it with high-level inscriptions, it might be possible to create a royal weapon, second only to a divine weapon. At that time, Hark's combat power would increase significantly, and he might even be able to fight against the weakest royal realm warrior. However, Gu Yu had taken a liking to it first, which made him somewhat unhappy, but he couldn't compete with Gu Yu.

"This is excellent material for forging swords! It's just a pity that this stuff is too hard. Years ago, a royal-level expert from my Hei family obtained this stuff and wanted to forge a weapon, but unfortunately, he sought out many weapon-forging masters, none of whom could melt it." Hei Fengxuan said at this moment. It is indeed material for forging divine weapons, but unfortunately, if you can't melt it, you can't forge it. Therefore, this stuff has become a useless thing.

"Unmeltable?" Gu Yu frowned. He had heard of this thing, but had never seen it before. Even though he was at the peak of the Emperor Realm in his previous life, he had never seen this thing.

"Kid, don't worry! I have a way to melt it." Long Yuan suddenly said at this moment. "Hmm! Although the things here are not ordinary, they can all be called rare and precious materials. If you can get your hands on them, it will be enough to improve the combat power of the war division you establish."

"It's a pity I can only take ten items," Gu Yu said. He did have the idea of ​​taking them all, but if he took them all, Black Wind Whirlwind could kill him!

"Hmm! This thing is very difficult to melt. Even the primordial spirit fire of a royal realm cultivator cannot melt it," Black Wind Whirlwind said upon hearing Gu Yu's doubts.

“Then I’ll take this too.” Gu Yu said directly. Long Yuan had already said there was a way to melt it, so what was there to be afraid of? Besides, he had already decided what to make with it!

“Alright!” Black Wind Whirlwind reached out and sucked the black gold essence into his hand, then handed it to Gu Yu.

"Consider this piece of black gold refined gold as my gift to you, and it won't count as one of the ten treasures." Although black gold refined gold is rare, it cannot be melted, so it's useless to Hei Fengxuan. It's better to give it to Gu Yu. As for whether the other party can melt it later, that's Gu Yu's business.

"Thank you, Your Majesty." Upon hearing Hei Fengxuan's words, Gu Yu immediately bowed to Hei Fengxuan. This bow was not fake; it came from the bottom of his heart.

"No need for thanks. Once you become powerful, just remember the Hei family," Hei Fengxuan said. He didn't need to pretend; that was his purpose.

"I will," Gu Yu nodded and said. He would remember the Hei family and would soon prepare a great gift for them.

"I want this Condensed Cone Flower; it will help me recover my cultivation." Gu Yu's gaze fell upon the Condensed Cone Flower. This Condensed Cone Flower was probably several thousand years old, and it would likely be useful even to a Commander-level cultivator. Of course, only four petals remained, indicating that the Hei family had used quite a few. Judging from its appearance, this thing originally had at least twelve or thirteen petals.

"Alright!" Black Wind Whirlwind didn't hesitate. With a flick of his hand, the Condensed Cone Flower flew over. Because he was afraid of losing the medicinal power of the Condensed Cone Flower, there was an energy barrier around it.

Gu Yu took the Condensed Cone Flower and directly stored it in his source space.

“This is…” Gu Yu took a few steps inside, and his gaze suddenly fell on the three source stones. The three source stones were suspended in the air. Although there was an energy shield around them, it still could not block the source stones they emitted. The source energy was extremely rich and pure. Even an ordinary person could prolong their life if they just took a breath of it. At this moment, Gu Yu’s gaze was fixed on the three source stones in front of him.
