Physical mage, challenge me to a solo duel!

Chen Guang was very pleased to hear that Wang Yi was willing to give it a try.

Just like police academy students get to experience Taser and pepper spray firsthand, you have to experience what it feels like yourself before you can use it on suspects.

So Chen Guang grabbed the metal semi-circular magic interference device and put it around Wang Yi's neck.

After the metal semi-ring touched Wang Yi's neck, thinner semi-rings immediately extended from both ends. With a "click," the two ends locked together, and then, like a collar, they encircled Wang Yi's neck.

"drop."

The metal collar made a sound, and then Wang Yi felt the originally stable magic power in his body suddenly become disordered, followed by a very uncomfortable feeling, a bit like chest tightness, and a bit like a stitch.

Wang Yi raised his hand to cast a light spell, but found that the magic power within his body was completely beyond his control.

If the magic within you was originally a well-ordered soldier, orderly, obedient to commands, and quick to respond to your instructions, then after putting on the metal collar, the magic transforms from a soldier into a one- or two-year-old child, running around aimlessly, squeaking and ignoring your words.

Wang Yi focused his mind and mobilized a small amount of magic power within his body, finally condensing a faint light source at his fingertips.

The first time he absorbed a regular-grade illumination spell, the effect was several times stronger than it is now.

If even a common-grade illumination spell is this difficult, it's simply impossible to unleash a more powerful spell that consumes even more magic power.

Chen Guang was genuinely surprised to see the illumination spell at Wang Yi's fingertips: "Your control over magic is quite good. Most high-level mages can't cast any spells once they're locked up."

Wang Yi's forehead was slightly sweaty as he dispelled the illumination spell.

His control over magic is actually average. Although he trains himself regularly, he is still far behind Wang Jiang and Jiang Yue, and his fine control is lacking.

However, the passive spells Resilience and Exorcism made Wang Yi's spirit even more resilient and powerful, enabling him to forcibly mobilize some magic power under such circumstances.

It was simply a matter of throwing bricks with great force; there was absolutely no skill involved.

Fortunately, the magic jammer only interferes with magic.

Wang Yi slowly clenched his fist, feeling the still surging power within him, and quietly breathed a sigh of relief.

Passive magic is like attribute points, constantly modifying the body and mind, improving the person's basic attributes. It does not require any magic power to be consumed, so even if the magic power in the body is disturbed, it will not affect the passive magic that has already taken effect.

This made Wang Yi a little envious. If this thing had a range of several hundred meters, he could wear the collar and charge directly into a group of mages. He would be absolutely invincible, killing mages like killing chicks, crushing them one by one without making a sound.

Chen Guang handed the phone that came with the glasses to Wang Yi: "You can control the magic jammer to turn on and off using this phone."

Wang Yi opened his phone and found the control page for the magic jammer. It showed that one neck ring was being activated, while the remaining neck ring and three magic cones were in standby mode.

As he closed the thimble that was opening, the metal collar around his neck beeped twice, then the clasp unlocked, and the collar folded into a semi-circle before falling off his neck, where it was caught by Wang Yi with lightning speed.

"Activating the magic interference device will increase the risk of cancer, but it's like smoking; it takes a long time to accumulate, it doesn't mean you'll get cancer immediately just by wearing it. Moreover, wearing it for a long time will cause considerable damage to the body due to the chaotic magic. However, considering that it's used by criminals, it doesn't really matter," Chen Guang reminded him.

Looking at the magic jammer, Wang Yi realized with a start: "With this, wouldn't the mage's advantage be completely gone? Well-trained soldiers wearing neck collars could easily crush a mage, wouldn't they?"

"It's possible to outnumber the enemy, but the actual effect isn't as great as you might imagine, since the range is always an issue." Chen Guang picked up the largest magic cone in the box and shook it a couple of times: "The disturbance range of the neck ring is only two meters, and this magic cone has the largest range."

"The disturbance range of this magic cone is three meters, which is large in some ways but small in others. And don't forget, three meters is the diameter, which means the effective radius is only one and a half meters. A single step can create distance, so the limitation is quite significant."

"You're also a mid-level mage, so you should know that when you advance to the mid-level, your body is strengthened. After the strengthening, your strength, speed, and reaction time are all higher than those of elite soldiers who have been trained for many years. Being unable to cast spells doesn't mean you can't fight back. A mid-level mage might not be able to beat an ordinary soldier in a fight, since hand-to-hand combat requires skill, but you can definitely outrun them."

Wang Yi remained silent. To be honest, when he advanced to the intermediate-level mage, he didn't feel anything in his body, and the enhancement he received was negligible.

Because those passive spells had already strengthened his body to an inhuman level, the advanced strengthening was like pouring an extra cup of water into a full water tank.

"Besides, cost is also a problem. The cost of a magic interference device is much higher than that of a magic detection device. For example, the production cost of this magic cone with a disturbance range of three meters is, to be honest, about the same as the cost of training a high-level mage. And I only have this one set."

Upon hearing Chen Guang's words, Wang Yi suddenly felt the neck ring in his hand become exceptionally heavy.

How much the hell does that cost?!

I want it even more now.

"Actually, the most practical one is this small magic cone." Chen Guang picked up the magic cone, which was about the size of a pen, and said, "When inserted into the chest, the magic cone will pop out barbs, and the cone itself is smooth. As long as it is inserted deep enough, it cannot be pulled out at all, and it can control a mage indefinitely."

"If it were made into bullets..."

"This is already the result of miniaturization. If you make it into a bullet, with this size and mass, plus the propellant, how big of a caliber would it be? You could call it a sniper cannon. It would be enough to shatter a person in half. It's better to just use bullets."

"That's true." Wang Yi nodded. He knew nothing about military research and development, so he didn't offer any unsolicited opinions.

Wang Yi benefited greatly from the casual conversation along the way, until the helicopter landed at the military airport in Zhuchuan City.

"These are the locations most likely to be where the plastic surgery monster is predicted by big data. You are in charge of these locations, and I will handle the rest." Chen Guang handed Wang Yi a map.

When Wang Yi opened the document, he found that the areas he was in charge of were mostly public places such as hotels, including Qifeng Tower.

The areas Chen Guang was in charge of were densely packed, and many were close to the city government, magic high school, and other similar locations.

After all, firstly, Chen Guang's magic perception is a legendary-grade magic with a very large range; secondly, due to Chen Guang's status, even official units can verify the identity of high-level mages, preventing situations where the truth is hidden from view.

After getting off the helicopter, Chen Guang called a field vehicle disguised as a taxi and took Wang Yi up: "Let's start the operation now. Just run back and forth between these few places, because no one knows when or where the plastic surgery monster will appear. Luck is sometimes very important. All expenses during this period will be fully reimbursed. Take a neck ring and a magic cone for temporary use. Remember not to lose them and remember to contact us at any time."

"Yes, sir!"
