After Ron finished writing the letter, he got up to find an owl in the Hogwarts communal owlery and entrust it with delivering the letter.

As long as they were given some food as a tip, these owls were happy to help Little Wizards deliver letters.

After writing the envelope and placing the quill on the table, he turned around and saw the pistol in Chen Yu's hand.

He immediately leaned over curiously, wondering what the object in Chen Yu's hand was.

Ron was straightforward and asked when he didn't understand: "What is this? It looks quite metallic and exquisite. Is it another item made by Muggles?"

Chen Yu nodded and replied, "This is a gun, a Muggle weapon."

As soon as Ron heard the name 'gun,' he suddenly realized: "So this is a gun! I used to hear my dad say that Muggles use these metal wands to kill each other. Muggles without magic can use guns to produce sounds and fire."

"Once, when Aurors were chasing a Dark Wizard, they accidentally broke into a Muggle's house, scaring the Muggles inside. That Muggle retaliated with a gun and almost injured an Auror. My dad told me that if a Muggle points a gun at you, there's no need to be afraid. Just use a spell to make their gun disappear before they can shoot, and then the gun won't be a threat."

Hearing Ron's naive remarks, Chen Yu felt a little like laughing.

This was also the view most wizards had of guns.

Their impression of Muggles with guns mostly remained in the 19th-century World War I era; they simply didn't understand the power of firearms.

Arrogant wizards were stuck in their ways, disdaining to study Muggle's ingenious tricks.

Just as Ron said, in the eyes of most wizards, a gun was just a metal wand that Muggles used to kill each other.

They naively thought that the way to counter firearms was to use a Transfiguration Charm or a mechanical spell to prevent Muggles from firing bullets from the gun, without considering the situation where a bullet could already pierce a wizard's head before he even had time to pull out his wand.

Only the most top-tier wizards realized how terrifying the weapons produced by Muggles truly were.

A Shield Charm could block bullets fired from the front but couldn't stop a sudden cold shot from a dark corner, especially when the threat was a thousand meters away.

Although the Statute of Secrecy protected wizards, allowing them to create a sense of superiority, living in a 'heavenly kingdom' while in a state of 'closed-door policy,' it also brought about a unique wizarding arrogance.

In the eyes of pure-blood wizards, pure-blood wizards were supreme, followed by half-blood wizards, then Squibs, and finally Muggles.

These wizards disdained learning Muggle knowledge and had no idea how much the Muggle world had changed over the past hundred years.

On this point, Chen Yu felt that Kamar-Taj's sorcerers were far more open-minded than wizards.

At least Kamar-Taj had WiFi signals, which was a sign of keeping up with the times.

Unlike Hogwarts, which didn't even allow the use of Muggle electronics.

Ron didn't know what Chen Yu was thinking. He was in a hurry to send a letter to his father, so after stating his understanding of guns, he quickly left the dormitory.

However, before leaving, he reminded Harry: "Although this thing looks cool, it's also contraband at school. Don't let the professors find out, or Gryffindor's house points will definitely be deducted!"

Harry accepted the gun with a subtle feeling.

He placed the gun under his folded invisibility cloak, thinking he probably wouldn't need it at school.

After Harry put the gun away, Chen Yu tossed an origin bullet to Harry.

Seeing what Chen Yu threw over, Harry fumbled to catch the origin bullet.

Having a gun without bullets and having a gun with bullets were two different concepts.

Harry had seen pistols and casings on his aunt's TV, but he had never seen an intact bullet.

Harry carefully pinched the bullet, observing the cold little fellow closely.

Watching Harry stare at the origin bullet, Chen Yu asked Harry, "Do you know how I eliminated the Troll?"

"Didn't you say you used a Confundo to make the two Trolls hallucinate, and then they fought each other to the death?"

"That's the official story. I said I used some illicit means to deal with the Troll, and that illicit means is actually in your hand."

Chen Yu sat on the bed, shaking his crossed leg, and continued to add: "I successfully knocked out the first Troll, but I didn't expect there to be a second one. You should have heard other Little Wizards say that Trolls are creatures with strong magical resistance; only their heads are a weakness. If you ignore the weakness, ordinary spells have little effect on Trolls."

"The second Troll was far smarter than the first. In an emergency, I used Transfiguration to turn wooden stick fragments into a pistol and Wood chips into bullets, which is how I dealt with the second Troll. However, using a Transfiguration Charm to turn Wood into a gun to kill a Troll was too absurd for wizards, and Professor McGonagall didn't let me tell the real story, so I falsely claimed to have used a Confundo."

"Was it really solved this way?" Harry felt somewhat unbelievable, yet it also felt reasonable.

If it was a firearm, it would indeed give a Little Wizards the ability to fight back against a Troll.

"I'm giving you a gun and a bullet because you bear the title of 'Savior,' and just as Ron said, you are a person destined for great things."

"But all people who do great things will encounter hardships and various enemies."

"You should have noticed that although Hogwarts is relatively safe, it's not entirely safe. For example, the Troll in the basement, and the Quidditch match; it seems various troubles surround you, forcing you to face danger."

"And you are just a first-year student who hasn't mastered many spells and doesn't have much ability to resist. Giving you a gun and a bullet isn't for you to kill anything, but to give you a certain deterrent and the ability to protect yourself when you truly encounter danger."

Harry listened carefully to what Chen Yu said. After much thought, Harry gave up thinking... Although Harry was relatively precocious, he was, after all, only a first-year student. He didn't understand the meaning behind Chen Yu's words, but he could feel that Chen Yu was good to him, so he also tucked the bullet under the invisibility cloak, placing it with the pistol.

Although Harry sometimes pondered the meaning behind Chen Yu's words, he quickly had no time to think about them.

Because the second Quidditch match was about to begin.

The second match was Gryffindor against Hufflepuff.

If they won against Hufflepuff, they would take the lead over Slytherin in the Quidditch tournament.

This was the only time in seven years that they had hope of achieving ultimate victory in the Quidditch tournament, and Wood was very determined, making training stricter than ever before.

Moreover, because Harry successfully caught the Golden Snitch in the first match, Wood placed great hope in Harry.

Regardless of whether it was heavy snow or continuous rain outside, Quidditch training never stopped.

Chen Yu watched Harry, who was exhausted and shivering from the cold every day, and could only sigh at the Little Wizards' vitality.

If ordinary people trained like this, it would have been fatal long ago, but the Little Wizards were like cockroaches.

In such extreme weather, Chen Yu had never seen Harry catch a cold.

Chen Yu felt that with such cold weather outside, it would be better to study the mysteries of magic in the dormitory than to practice Quidditch outside.

Ron also received a reply from his father. Unsurprisingly, the financially struggling Weasley parents still took on the business.

Although payment was in gold, the Weasley family had channels to convert this gold into Galleons.

Do not underestimate members of the 28 pure-blood families; even if the Weasley family seemed down on their luck, they still held considerable influence and status within the Ministry of Magic.

However, Arthur's reply stated that the production cycle was somewhat uncertain because the materials needed for the Undetectable Extension Charm suitcase were not available at the Weasley home and required contacting suppliers through channels. Moreover, the production process was quite intricate, so it might take some time.

Chen Yu expressed understanding. Anyway, he wasn't in a hurry, and Tony wasn't pressuring him, so slow and steady wins the race.
