Ethan turned around in surprise, utterly astonished by the boy's current appearance.

The boy was wearing a purple wizard hat, the kind only worn on Halloween.

This hat had a pair of red eyes and a sinister mouth; its eyes glowed red, and its mouth glowed blue, like an evil piece of equipment capable of devouring people's souls.

“Something’s wrong with that boy!”

“Kill him quickly!”

The terrorists standing at the cave entrance continued to fire, but the bullets harmlessly struck an invisible wall without causing any ripples.

“Petrificus Totalus!”

The boy cast another spell.

Several terrorists who were firing suddenly turned into stiff wooden figures without any warning, their arms and legs together, falling rigidly to the ground.

This scene utterly terrified the disorganized mob.

“Devil!”

“Devil!”

“That boy really is a devil!”

“Help! I don’t want to fight a devil!”

Some scrambled away, clutching their heads, some continued to vent their fear with firearms, and some simply knelt, begging the devil for mercy.

They could understand the muzzle flashes of firearms but could not comprehend the fear of unknown magic.

A bald terrorist, whose appearance differed from the other Miscellaneous soldiers, strode into the cave, carrying an RPG.

Seeing his subordinates in disarray within the cave, the bald man was furious, knowing that the enemy was behind everything, and fired a single-person rocket at Chen Yu and Ethan.

The warhead collided with the invisible wall, erupting in a violent roar.

The intense heat was blocked by the invisible wall.

Chen Yu was clearly startled by the power of the rocket launcher fired by the opponent, and subconsciously used his most familiar, most practiced, and most proficient spell.

“Avada Kedavra!”

Green magic rapidly converged at the tip of his wand.

A light cannon, with a radius of a full meter, shot out from the tip of his wand.

All enemies affected by the Avada Kedavra immediately fell, as if their lives had been harvested by the merciless Grim Reaper.

The first to fall was the man holding the RPG, who seemed to be the leader, and those around him were also unable to escape.

One Avada Kedavra instantly wiped out the group of terrorists who had entered the cave entrance.

Ethan was stunned.

The clash between science and magic collided in Dr. Ethan’s mind.

He completely couldn’t understand how Chen Yu had done it.

Why did a wooden stick emit a dazzling green light?

Why did everyone touched by the green light fall?

Why was the boy, who had been so weak just moments ago, now standing perfectly fine behind him?

Ethan’s eyes were filled with fear, not of Chen Yu, but of his own ignorance.

This was Chen Yu's first time killing someone, and the feeling was completely different from killing an Acromantula or a Troll.

Looking at the pile of fallen bodies, Chen Yu felt no guilt or regret.

He knew these people were terrorists and had come with the intention of killing him.

Those who kill will be killed.

But his body still trembled uncontrollably.

Dr. Ethan, seeing the boy in the wizard hat trembling slightly, realized that no matter what power the boy in front of him wielded, he was still just a boy of about 11 years old.

He crouched down, patted his shoulder, and comforted him, “Child, this isn’t your fault. These people deserved to die…”

Just then, a vibrating sound, like steel plates contacting the ground, came from deep within the cave.

Every step was accompanied by a mechanical clanking sound.

The ground vibrated slightly, and Tony Stark, piloting the first generation MK1 Iron Suit, arrived at the cave entrance.

He vigilantly looked around, saw the scattered bodies lying at the entrance, and saw Dr. Ethan.

He saw Dr. Ethan holding the child who had fallen at the entrance of the terrorist base two days ago, comforting him in a low voice.

He saw the boy wearing a wizard hat, the kind only children wear on Halloween.

Tony Stark lifted his mask; he was very happy that Dr. Ethan was alive.

“Ethan, did you do all this? I didn’t expect you to have this secret weapon… and what’s going on with this little guy?”

Dr. Ethan shook his head and said to Tony, “No, I didn’t do it. He did. He saved me, and he killed these enemies. Tony, I suspect he is a legendary sorcerer.”

Chen Yu felt much better. Although the first kill made him a bit uncomfortable, with an adult's mindset, he quickly adjusted.

Seeing Ethan comforting him, Chen Yu was about to say something when Tony, wearing the Iron Suit, interrupted him: “Sorcerer? Ethan, are you kidding?”

Tony Stark clearly didn’t believe in the existence of magic in this world.

Before Dr. Ethan could retort, Tony put on his faceplate and said to Ethan, “Fortunately, you’re still alive, Ethan. Now it’s time for our revenge!”

After speaking, he controlled the Iron Suit and walked out of the cave entrance to eliminate the remaining enemies.

Soon, violent roars and gunshots echoed from outside the cave.

Ethan patted Chen Yu’s shoulder again: “Child, I’m very sorry that your hands have been stained with sin. When we get out, I will have Tony hire the best psychologist in the world to treat you.”

“Thank you, Dr. Ethan.” Chen Yu adjusted the destroyer hat on his head and replied to Ethan, “Sorry, you’ve mistaken my profession. I’m not a sorcerer, but a wizard. Do you know who these terrorists are?”

A hint of heartache flashed in Ethan’s eyes; he didn’t want the child to be exposed to too much darkness.

But since things had come to this, Ethan could only say, “These terrorists are subordinates of the ‘Ten Rings.’ This is a mysterious organization dedicated to destroying world peace at all costs. They burn, kill, plunder, commit all sorts of evil, and stir up terrorism everywhere. They are a group of utterly wicked people.”

Another explosion sound came from outside the cave entrance; the huge noise made the entire cave tremble.

Dust fell from the cave ceiling, making Ethan’s head dusty, looking as disheveled as if he had just returned from working at a construction site.

Chen Yu was in the same state, but the wide destroyer hat blocked the dust, so he didn’t look as disheveled as Dr. Ethan.

He said to Dr. Ethan, “Thank you for your comfort, Dr. Ethan, I feel much better.”

Saying that, he picked up his wand and aimed it at Ethan.

At this moment, Ethan’s heart skipped a beat, fearing that the wand in the child’s hand would shoot out a green light and take him away too.

“Scourgify.”

“Accelerato.”

As Chen Yu finished chanting, Ethan was surprised to find the dust on him quickly disappearing, and even more pleasantly surprised to find his already bald hair rapidly growing, experiencing a second spring.

Soon, a new-look Dr. Ethan with wavy hair appeared before Chen Yu.

With thick hair, Dr. Ethan looked much younger.

Chen Yu used a Hair Regeneration spell, which, like the Toenail Growth spell, is a branch spell of growth spells.

It was then that Tony, controlling the Iron Suit, walked into the cave, saying as he went, “Ethan, little guy, the terrorists have all been eliminated. We can leave now.”

He then saw Ethan’s new look, whistled, and exclaimed, “Dr. Ethan, your new look is really cool!”

Then he said to Chen Yu, “Little guy, I’m starting to believe what Dr. Ethan said. Are you really a sorcerer? Can you do one for me later? I’ve lost a lot of hair recently from staying up late working on the Iron Suit.”

Clearly, with the threat gone, Tony Stark had reverted to his usual playboy billionaire persona.

Chen Yu still strongly identified with his identity as a Hogwarts student.

Chen Yu emphasized again, “It’s a wizard, not a sorcerer.”
