Vincent noticed that each book has different designs and there is already a card containing its information below them.

[ Grimoire of Inferno Arrows – Grade C ]

[ Inferno Arrows: An ability that allows the user to create 10 arrows made of blue fire. It has a high penetrative force and requires a Mana Shield at the Perfect State to defend against each arrow. ]

[ Number of 'Inferno Arrows' Pages: 18 ]

[ Number of Blank Pages: 22 ]

Vincent read the information about the black grimoire with a bloody fire designed on its cover.

'So it's like that, huh…'

He then decided to appraise the same book to see the difference between the information that the system will provide him and the card written on the shelf.

Ding!

[ Appraisal has been successful. ]

[ You have discovered a Tome of Skills ]

[ Tome of Skills ]

Remarks: You can only store Tier 3 Mana Arts and below. Stored Skills will be enhanced in every enhancement. ]

Vincent took his time to read and understand this grimoire. Well, it's called tome by the system and it seems that this is indeed a very valuable weapon since it's an Epic Rank!

'Incredible… Since the skills are already stored within the pages of the book, you only have to trigger them by using a little bit of mana. No wonder anyone can use this ability.' Vincent can finally understand why these treasures were truly important.

However, it confuses him since they are being stored within this treasure vault instead of being handed over to the soldiers fighting on the front lines.

Anyway, he could care less about it as he decided to find the best Tome of Skills for his usage. He can only select one item here after all.

He spent a total of 20 minutes checking the items to find the most suitable skill that he needed right now.

"I'll take this…"

In the end, he chose a thick red book with a huge snake eye protruding from its cover. It looks realistic and Vincent wouldn't doubt that it had really come from a Savage Beast or even a Magic Beast.

The card beneath the item says that it is the Grimoire of Living Armor. Right now, Vincent is lacking in terms of his defensive capabilities.

Although his skin, muscles, and bones have been strengthened several times after becoming an Aura Knight, he's aware that high-ranking weapons and special Mana Arts can still penetrate his defenses.

He had previously seen Klaus, the Arch Knight of Red Rose Knight, and knows that just one of his sword strikes could easily kill him. There was no way that his body and a simple Mana Shield would stop such powerful strikes.

"Thirty pages of Living Armor… That should last for a while." Vincent mused as he confirmed that the living armor's duration is actually ten minutes until it was destroyed.

"General Yves… Can you tell me how to use the blank pages of the tome? Can I also place a Mana Art inside one of them?" Vincent asked as he showed the general the item that he selected.

"Well, it's quite tricky to store a Mana Art. It's certainly possible but only those with a high level of attainment in Mana Arts Research can do it. After all, if you made a mistake, not just the page but even the whole grimoire might be destroyed. There is another option though, it's to ask a Barbarian Mage to store one for you." General Yves said.

The second option is, of course, impossible since Mana Arts Practitioners and the Barbarians outside their kingdom were sworn enemies.

Vincent can only sigh as there was no way for him to reach high-level attainment in Mana Arts Research since he hasn't even attended an academy.

Soon, Alfred and the others also found the grimoires suited for them as they left the treasure vault.

Without taking any rest, Vincent was escorted to visit the infirmary where the Divine Doctor Ji and Poison Expert Severin are currently at.

Soon, he entered a hall filled with many patients having the same symptoms of poison in their bodies. They all have black veins appearing on their skins and most of them started from their eyes that would web through their whole bodies.

"Ugh… Doctor, it's painful… I want to sleep."

"Doctor… I can't die yet. My wife is waiting for me. She was pregnant when I left for battle…"

"I can't feel my lower body anymore, doctor…"

"Aackk… M-my stomach…"

Vincent heard the cries of the conscious patients and realized that this poison being used by the barbarians is indeed quite scary.

He can tell that the people on the bed weren't ordinary as well. He can tell that they were Mana Arts Practitioners as he could sense how they are circulating their Mana Core in hopes of alleviating the pain caused by the poison.

"Vincent, you're here. What do you think of the situation?" Divine Doctor Ji asked as soon as he saw Vincent entering the infirmary.

"It looks bad, doctor Ji. Do you have a way to help them?" Vincent asked as he felt really bad about these people. They were courageous warriors of the Arms City who were fighting against the invasion of the barbarians.

Since Vincent knows that his parents were killed during a Barbarian Invasion, he couldn't help but sympathize with these sick patients.

Divine Doctor Ji then helplessly smiled before he answered.

"I'm not sure if it will be effective since I haven't seen this kind of poison before. However, thanks to doctor Severin's records of their symptoms, I noticed that seven of the ten symptoms he listed were similar to another poison I have treated before. The potion I'll make might be able to help before I use my healing hands…"

Vincent then looked at Poison Expert or perhaps Doctor Severin. He wasn't too old and appears to be in his forties. He has black hair with a tinge of silver and he appears quite elegant with his appearance. He doesn't seem haggard like the Divine Doctor at all.

"Doctor Severin, I was sent by the General since he heard about my skill with potions. I hope I'm not disturbing the patients here." Vincent said.

"Oh? You're too polite. I don't really mind. Currently, I'm not really sure how to treat these people. I have 40 patients right now and I'm doing three different types of treatment for some of them."

"Three types of treatment?" Vincent repeated.

"Yes, unfortunately, none of my treatments shows any improvements at all. It's a good thing that the Divine Doctor has come so I finally have a path where I could start again." Severin explained.

A few hours had passed as Doctor Ji started making potions as soon as the herbs and ingredients he needed had arrived.

The Divine Doctor made a batch of potions for a few hours as he finally started his treatment. Severin selected five poisoned people and tried to cure them with the potion.

"It's working!" Severin exclaimed as soon as he saw that the symptoms started dissipating in a matter of seconds.

Unfortunately, even after the Divine Doctor continued and used his healing hands, the disease did not disappear at all.

At most, it looks like they have just extended the patient's life.

After observing the five patients for almost six hours, they confirmed that the disease brought by the poison started reappearing albeit at a slower rate.

"It's still lacking…" Doctor Ji and Expert Severin muttered at the same time. They know that the potion that the doctor made was working but it can't completely remove the poison as if it's lacking some potency.

In the end, they looked at Vincent who was supposed to be knowledgeable in potion.

"Alright… Doctor Ji, give me a few of those potions you made and I'll try to do something about it, but I might need a few days for this since I need long preparation. In the meantime, please take care of the patients." Vincent finally said after contemplating.

Since Severin is from the Zemin Clan, he's planning to leave a good impression on him as he might be helpful once he decided to reveal his plans to meet the daughter of the current patriarch.

'I'm not sure how would they react if I informed them that I'm their young lady's fiancé. If I got acquainted with Sir Severin, he might at least try to defend me… right?' Vincent wryly smiled at his situation.
