Chapter 141: Another Bottleneck

"Alright… I surrender. Haa… Haa..." said Vergil while trying to calm his ragged breath.

While Vergil was sweating heavily, Angus didn't even break a single sweat or have rough breathing.

"So, who do you think is stronger, brother?" asked Angus with a teasing smile.

Hearing this, Vergil rolled his eyes, "Urrgghh… How come you didn't even break a sweat? are truly still a grade one?" asked Vergil.

"According to Father and the king himself, I am still a grade one combatant. Though they might say that I may defeat a grade two combatant if I try." replied Angus in a thinking pose.

"Ehhh.. Damn, that's kind of cheating. How could you even get that stronger?" said Vergil.

"By training and a little bit risking my life." replied Angus.

"Training? Risking your life? Fine, keep your secret to your lovely brother." said Vergil in a sarcastic tone.

"Alright, then I will keep it to myself." replied Angus blatantly.

"That's supposed to be sarcasm!! Huft.. Anyway, you said that father and the King himself also know about your strength?" said Vergil.

"Yep, though it is more likely to be found by the king himself rather than I revealing towards him." said Angus.

"Hee… When did you have time to meet the King?" asked Vergil.

"Ohh.. It's when I... " said Angus as he told Vergil about his experience in the Orces kingdom.

However, Angus only says that he is only becoming part of Master Valeron's assistant rather than telling Vergil he is creating the potion.

Since King Nexus's miasma wound fully healed, the Miasma Curing Potion began to sell like a hot cake. Many nations offer enormous prices to the Heart Kingdom to buy the potion.

Although the war with Monster Overlord is over, such a life-saving potion is still useful, especially knowing that it could heal Miasma-based wounds. All the nation didn't even bat an eye for paying a huge price to buy this potion.

Because of this reason, even the Heart Kingdom itself wants to reduce the potion circulation in the market will be difficult. The Heart Kingdom couldn't refuse such an enormous offer from another nation.

Accepting these deals from various nations from the last few months is almost the same as Heart Kingdom's total income in ten years or more. Moreover, it only comes from a few nations. 

There are still many nations that are waiting to buy such a legendary potion. Many of them are trying to wait until the price to go down a little bit before buying. However, all of them also want to procure such a potion.

As for Angus, the creator, he also got some of the benefits. Although most of the precious material and profit went towards the Heart Kingdom, Angus still gets some part. It could be said he is the wealthiest young high noble in the Heart Kingdom.

Furthermore, he also gets many privileges from King Leon himself inside the Heart Kingdom. In terms of merit and contribution to the Heart Kingdom, he also already surpassed many other nobles.

After chatting a little bit, the two brothers went back to their dorm. Looking at Vergil's same attitude, Angus feels relieved that his brother is not jealous like in his previous life. He honestly didn't want to get another bloody brotherly fight again.

Thinking about his brother, he also remembers his oldest brother Jason. Although Angus's relationship with him is not good, he also still cares about him. He is still a little bit afraid about Jason's reaction when Angus shows his true strength at a later date.

However, he already decided to stand on the peak. So, he will not back down even if his oldest brother disapproves of him.

Soon, time goes by. While Angus is enjoying his peaceful life inside the academy, he enters the age of fourteen. During all this time, Angus finally managed to learn the Dark Elf language. But, learning the Dusk Language is another matter.

To be exact, he could learn it but not vocalize it. According to the book that he found in the hidden chamber, powerful languages like Dusk Language need many requirements just to vocalize one word.

After researching it for a few months, Angus found few basic requirements to speak or vocalize the Dusk Language. First, it needs enormous mana. 

Powerful languages such as Dusk Language consume huge mana just to vocalize it. This is also the reason why this language is dangerous. Some words could even affect the world itself or create strange effects like spells.

Second, it needs knowledge of the word, such as the intent and own understanding about the word. The more substantial and profound the knowledge of the word, the stronger its effect.

Then, it needs specific requirements such as time, location, or other particular conditions. In the Dusk Language case, it could only be used after the sun goes down.

After trying it many times, Angus still couldn't vocalize in one word of Dusk Language. At first, he didn't know the reason, but he could feel it because he lacked mana.

According to some book and teacher Elis's explanation, powerful language will consume mana with the same amount of casting four or five circle spells.

At first, Angus thought to trade all his soul points into his slow growth mana. But, he noticed that his body would soon reach a bottleneck again. He needs to upgrade his mana core to enlarge his mana reservoir further.

Upgrading mana core is almost as complex as opening Gate of Life, however, with less risk since it only upgrades into grade two. If it is an upgrade such as a high grade like getting into grade six, it will take time and risk death in case of failure.

Furthermore, upgrading into grade two is more complicated than upgrading into three. Although there is almost no risk in upgrading into grade two, it is the phase where people upgrade their mana core for the first time.

There are various kinds of ways to upgrade the mana core. The problem is people need to find the correct route by themself among all of these ways. This is why second-grade combatant is low in number while first and third-grade combatants are pretty abundant.

Since Angus knows it will take some time before entering the second grade, he decides to give up learning the Dusk language and unraveling the secret of the hidden chamber for a while. 

He will get back to it later when he could use Dusk Language or have time in the future. Besides learning the Dusk Language to deepen his understanding, Angus also improved his body by continuously practicing and helping Jayna's training.

The relationship between the two is becoming more profound as they can understand each other's personalities better. Although Angus wants to stand on the peak, he also likes to take things easy. If he couldn't enjoy his current moment, it is not different from being dead itself.

As for Jayna, who keeps pursuing power, she is more calm and mature to enjoy her everyday life. Because of her practice in [Arctic Heart], she also becomes colder towards others besides a few of her friends like Millie, Mia, and of course, Angus himself.

Now, the two couples are enjoying the sunset like usual inside the Spring Dorm garden. 

While enjoying the sunset, "Angus, what happens if there is another strong man that wants me?" asked Jayna out of nowhere while sitting beside Angus.

"Isn't that obvious? I will beat the crap out of him, especially if he tries to hurt you." said Angus back while keeping reading a book.

Hearing this, Jayna could only nod blushingly. "T-Then, I will continue my training. I can't have the other men getting killed by you." said Jayna returning to her training.

While the two couples enjoy their time inside the academy, inside the Roundel city where the elf race leader resides, one of the elf leaders opens his eyes from his meditation.

"I see… It's finally that time again." said the elf leader.

The other elf leaders in the room also opened their eyes, "So, it is that time again. I wonder if there are notable youngsters that will survive this time." said Vandor, one of the elf leaders.

"If I am not wrong, many of the last survivors could reach the seventh grade now." said Luke.

"Whatever it is, there will be a lot of casualties as usual. I hope they don't become too greedy." said one of the elf leaders.

"Alright, Let's send the notice to all the nations first." said Vandor.

"Yes, let them know that the Endless Battlefield dimension is going to open." said Luke.

Soon, news about the Endless Battlefield dimension spread across the world. In Firuman, there is a lot of secret dimensions that are left behind from the ancient civilians.

The Endless Battlefield dimension is one of the oldest dimensions that exist in the Firuman. Not only the oldest, but it is also the most dangerous because of their rules. Some ancient secret dimension like Endless Battlefield has a law or requirement for a person to enter it.

One of the Endless Battlefield dimension laws is no more than fifteen years old to enter the dimension.
