Physical mage, challenge me to a solo duel!

"Only beginner-level mages are allowed to enter? I see..." After a moment's thought, Wang Yi understood the true purpose of this restriction.

The most obvious example is that without this restriction, a top-tier mid-level mage team like Huang Ya and Mo Yu could easily wreak havoc inside an F-level interdimensional passage.

After all, the strongest beings in the "Bridge" level interdimensional passages are only mid-level magical beasts.

Wang Yi recalled the first time he saw a pack of wind wolves hunting a herd of black-hoofed yak when he first entered Lingnan Shaqiao.

Both the wind wolf pack and the black-hoofed yak herd have calves within their groups.

Clearly, the monster race is also able to successfully reproduce and multiply within the interdimensional passage.

In addition, with the magical beasts that occasionally slip in from the entrance to the Demon Realm, the passage between the two realms can continuously provide magic crystals simply by hunting them according to their numbers.

So, if there are no restrictions, some top-tier mid-level mage squads could theoretically wipe out an F-level interdimensional portal.

If too many monsters die and new monsters haven't been added yet, the balance will be disrupted, causing a supply shortage and a sharp decrease in the production of magic crystals.

The authorities certainly don't want to see this happen.

From the official perspective, each interdimensional passage is a magic mine that sustainably produces magic crystals.

Just like the arms races that countries used to engage in, a magic race is now taking place between nations.

Although the major powers maintain a facade of peace, their methods of verbal sparring and sabotage have never ceased.

"With no one to back you up, the mortality rate when entering the interdimensional passage for the first time and fighting against magical beasts is actually very high. That's why I didn't choose this kind of restricted interdimensional passage for my initial training," Bai Yu said.

Wang Yi nodded in agreement.

In Lingnan Shaqiao, if it weren't for Bai Yu and Zuo Jinxiu, Wang Yi's life would have basically ended there.

This is also due to the presence of powerful team members like Jiang Yue and Wang Jiang.

These two are far stronger than ordinary novice mages. Without them, most first-year high school students would have been wiped out when they encountered the Fire-Patterned Black-Tailed Leopard.

Bai Yu suggested, "However, you could consider going to the F-level interdimensional passage during your vacation. It's not for fighting monsters; the abundant magic power within the interdimensional passage can significantly speed up your advancement."

At this point, Wang Yi raised a crucial question: "Since the F-level interdimensional passage charges a fee, can the magic crystals obtained inside be brought out?"

"Okay." Bai Yu glanced at Wang Yi, her eyes carrying a strong warning: "However, magic crystals are, after all, officially controlled items, and private transactions are restricted."

If you plan to sell it on the black market, you could face criminal charges if caught.

"Haha... How could that be? Old Boss, you know me, I never do anything illegal." Wang Yi chuckled twice, it seemed he still needed to consider other ways to make money.

"That's why I'm reminding you, because I know you." Bai Yu pouted.

"So this is how magic crystals on the black market come about?" Wang Yi had never been involved with the black market before, so he was a little curious.

"Most of them, right? This is also the choice of some freelance mages, after all, it's a quick way to make money. If the army were to recycle magic crystals, their value would plummet, which is almost a tenfold difference. It's hard for anyone not to have such crooked thoughts."

Wang Yi clicked his tongue, puzzled: "Why would anyone buy magic crystals on the black market? Are they particularly cheap there?"

"It won't be cheaper than regular specialty stores, and it might even be more expensive. After all, buying magic crystals on the black market doesn't require identity verification or qualifications, and it won't be recorded," Bai Yu said meaningfully.

"This is because the mages active on the black market, apart from some criminals who cannot buy magic crystals in the specialty stores, are mostly foreign forces."

Just like your healing rays and light cage, they weren't produced domestically, and the French government prohibited their distribution abroad, yet you still absorbed them.

Wang Yi suddenly realized that he remembered seeing on the internet that the magical beasts in the interdimensional passages between different countries were different, and naturally, the magic they possessed was also different.

Wang Yi wanted to ask more about the specifics of the F-level interdimensional passage, but unexpectedly, footsteps came from downstairs.

Hu Lili staggered up, probably because the effects of the local anesthesia hadn't worn off yet.

Qi Xiaohao, who had been listening to Wang Yi and Bai Yu chatting idly, hurriedly stepped forward and helped Hu Lili to sit down on the sofa.

Not long after, Zhang Miaoyi, having finished cleaning up the operating room, returned to the living room.

After lying down for half a day, Bai Yu finally got up and went to greet Zhang Miaoyi, opening her arms to give her a big hug: "Thank you for your hard work, Sister Miaoyi."

Zhang Miaoyi reached out and touched Bai Yu's shoulder, rejecting the enthusiastic hug: "Let me go change my clothes."

After saying that, Zhang Miaoyi went into the room, took off her surgical gown, and changed back into her home clothes.

Although she has long since retired from practicing medicine, Zhang Miaoyi still retains some habits and is reluctant to wear surgical scrubs and have too much contact with other people.

"Sister Miaoyi, thank you for your hard work." Bai Yu kept thanking Zhang Miaoyi, linking her arm with his.

After all, removing scars from students wasn't originally Zhang Miaoyi's responsibility; it was Bai Yu who took on the task for her.

"Alright, you've already finished your shift, and you're only now saying thank you?" Zhang Miaoyi scolded playfully, then leaned close to Bai Yu's ear and whispered, "Your students are still here, mind your teacher's image."

"Hehe, it's okay, besides, we're not at school right now." Bai Yu didn't seem to care much.

Or rather, Bai Yu didn't just see the three people present as students.

During their journey to Lingnan Shaqiao, Bai Yu, who was hiding in the shadows, witnessed their struggles, hardships, changes, and growth, and had long since accepted their identity as mages.

Although Bai Yu was much stronger than them in terms of strength, he still regarded them as equals in his heart.

Moreover, the age gap between Bai Yu and Wang Yi is not even as large as the age gap between her and Zhang Miaoyi.

Although the two of them look like sisters standing together right now.

In fact, Zhang Miaoyi and Bai Yu are fifteen years apart in age.

Zhang Miaoyi possesses advanced medical magic; she can easily cast a couple of spells on herself every day, and her vitality will be overflowing.

Time seems to leave little mark on her; at thirty-eight, she looks like a twenty-eight-year-old older sister.

Since Hu Lili's surgery was already completed, the students didn't stay long and left after sitting for a short while.

Bai Yu wanted to tell Wang Yi about Chi Jiayan's arrest, but it wasn't convenient to say so because Qi Xiaohao was always nearby.

Wang Yi didn't tell anyone around him about this, so Bai Yu had to find another opportunity to tell him privately.
