After a day, Vincent managed to enhance one of the potions into +9 and tried it with the patients.

As expected, it did work perfectly and one potion was enough to cure three poisoned people. This news immediately attracted the few high-ranking nobles within the Arms City including those within the few Clans who had entered the city to protect their borders.

Apparently, the 40 or so patients within the infirmary weren't the only ones affected by the poison.

It was only because of the limited space, that the others had to remain under the care of their clan or sect.

At a certain courtyard not too far from the Blue Storm Castle.

"Quickly! Bring those infected by the poison to the Blue Storm Army's castle." A man in his forties ordered his subordinates as soon as he heard the report.

He has long red hair and a lean figure. At the moment, he wasn't wearing any clothes on his upper body showing his well-toned muscles. He was doing his daily routine of practicing his sword swings when the news came in.

His name is Florent and he is one of the Guardians of the Jung Clan. This clan had similarly sent a portion of their forces to the Arms City to fight against the invasion.

That's right, aside from Zemin Clan, the Jung Clan, and the Santer Clan had sent part of their elite forces to the city.

"If we get plenty of supplies of that antidote they made, we will no longer have to worry about those audacious barbarians…" Florent clenched his fist as he has been worrying about this problem for a while now.

If he's not worried about their poisons, he would already lead his clansmen to fight a few battles against the Barbarians.

The other clans or noble families had similar reactions to this situation.

They had all made preparation to either transfer their patients to the Blue Storm Castle or get the medicine from them directly.

During this time, Divine Doctor Ji and Poison Expert Severin did not claim Vincent's achievements as they have given the credit to his skills in potion brewing.

Thanks to that, his identity was dug up by these people as they confirmed that he was actually an honorary knight of Count Miller from the Marshall Clan.

Three days had quickly passed and Vincent managed to upgrade all the 12 potions he received from Divine Doctor Ji into +9 potions. During this time, his fame had spread throughout the city although he was a bit clueless about this.

After all, his modified potions were able to cure a disease or remove the poison which even the Divine Doctor Ji and Poison Expert Severin were having trouble with.

There was no way that people will ignore this skilled individual as he might be able to save many more lives in the future.

In another meeting hall within the city, a group of five important figures was gathered as they were having a meeting.

"He's only an honorary knight… We can still recruit him and be our exclusive Potion Master. Our Clan greatly lacks people who were capable in this field. Our Clan Head would surely be happy if we can bring him back to that clan. Don't you think so?"

A fairy-like woman in her late twenties said with an excited voice. She has long black hair tied in a ponytail and wearing a long white robe making her seem ethereal.

Although her face is hidden by a white veil, her figure and angelic voice would certainly make everyone imagine her enchanting beauty.

The four other men who were listening to her didn't immediately agree as they voiced their opinion.

"We might have to wait until we stopped the invasion. In the meantime, we will certainly send gifts to him as a sign of gratitude for helping our men."

"That's right… Besides, he is currently under the protection of Hailstorm General. This Vincent seems so busy at the moment and I heard that he's only ordering the servants if he wanted something outside the castle. We are basically unable to talk with him." One of them said as he shook his head after thinking about it.

It seems that he already tried to approach Vincent but was blocked by the castle guards.

"Hmm? Is that so? Should I try and recruit him myself?"

The beautiful lady suggested. However, the four men immediately denied the idea.

"Lady Yulia, I don't think it's a good idea. Since he's already acquainted with Sir Severin, I'm sure that it would be a lot easier to recruit him. I think that we should focus on returning to the front lines and stop the Barbarians' advance."

A young man wearing luxurious blue and golden robe said with confidence. Although he also wanted to take Vincent to their Clan, the matters of the Barbarians are more important.

His name is Romain Zemin and one of the few people in the Zemin Clan who has a noble title to be inherited.

"Hmph! We'll ask Severin once he returned then… Anyway, how's the situation of Young Miss Lesley and the others?" Lady Yulia then changed the topic as they get to the main focus of this meeting.

Apparently, there are five layers of defenses arranged by the City Lord. Luckily enough, only the fifth layer of defense has been breached by the Barbarians after a month of invasion attempts.

"Miss Lesley is together with a couple of Arch Knights… Even the Patriarch sent another Adept Mage to protect her in secret. We shouldn't be worrying about their situation at the moment. As for the potion or antidote to fight against the Barbarian Poison, a diluted version of it was confirmed to be effective as long as it's within an hour. We shouldn't expect a lot of problems until next week."

Romain reported as he was mainly tasked to maintain the communication between Lesley's group and their team within the city.

"Very well, I guess we should address another issue about the Celestial Mountain." Lady Yulia said as her face turned serious.

She also knows that even though the matter at the front line is very important, they don't have to worry a lot as long as the two Arch Knights were still protecting the young miss.

"We confirmed that a few Celestial Beings together with their contractors has been gathering at the Celestial Mountain. I don't think that we should join their hunt."

"Is it really confirmed that there's a Celestial Beast present? How old is it?" Yulia asked.

"It should be a young Celestial 3 to 4 years old based on the reported fluctuation of mana around it. There was also a message that the elite contractor from Troy Clan was sighted."

"Elite Contractor? Are you telling me that Joran was there?" Yulia frowned as soon as she heard this.

Many people may not be aware but the higher-ups of the large clans and sects already heard the news about Joran Troy obtaining three powerful Celestial Beings.

It was even rumored that there is a Numbered Celestial among those three.

In the end, their meeting concluded and they decided not to join the mess in the Celestial Mountain until they confirmed that the Barbarian Invasion for this year has been completely repelled.

Anyway, they estimated that as long as they killed about ten thousand or more barbarians, they would certainly retreat and recuperate for the next few years before they would decide to launch another invasion.

In a certain courtyard within the Blue Storm Castle, Vincent can be seen holding a vial of potion with an ecstatic expression.

"At last! Mana Upheaval Potion +10! I did it!"

Over three days had passed after Vincent arrived here in the Arms City, and he finally managed to enhance this potion to its limit!

Previously, the +7 version of this potion can only provide him additional 210 units of mana with a side effect similar to an aphrodisiac. However, as soon as he completed the +10, he confirmed that there is no longer any side effects and he will receive a total of 410 points in his mana!

Without any hesitation, Vincent decided to consume the potion!

Gulp!

At first, he didn't feel anything after taking the potion, but after several seconds, his body started sweating a lot as he removed all his clothes…

Soon, he felt like something in his stomach was about to explode!

'W-what? I thought there was no side effect?!'

Vincent felt horror as soon as he realized that something was wrong.

'Shit! Can I not increase my Mana Capacity that much? Am I lacking physically?!' Vincent gritted his teeth as he felt that he couldn't endure it any longer.

He realized that the Mana Core within his body was about to explode!

Soon, several footsteps can be heard as they are hurrying at Vincent's courtyard. They could similarly feel the violent storm of mana forming around his courtyard!

Even General Yves was alerted as he immediately went to check the situation.

"Divine Doctor Ji, what's happening?" General Yves asked as he noticed Doctor Ji and Severin waiting outside.

"I think that Sir Vincent encountered a problem in his Mana Cultivation…"
