Fairy Tail: You can become stronger by spending money.

Luffy Card.

Born a rubber man, he is not afraid of electricity at all. This is also the reason why Cheng Feng dared to come to the Thunder Swamp to collect Thunder Swamp Flowers.

But even so, Cheng Feng finally waited at the bottom of the Thunder Swamp for three days and three nights. When he was so hungry that his chest was sticking to his back, he finally waited for the Thunder Swamp flowers to bloom.

Cheng Feng quickly collected ten blooming Thunder Swamp Flowers, sealed the broken part with magic power, and stuffed them into his game backpack.

Then he swam out of the thunder swamp, took out dry food and water from his backpack and started eating them in big gulps.

After eating and drinking, Cheng Feng recovered some of his magic power and made sure he was in peak condition. He then replaced the Luffy card and left the Withered Swamp smoothly according to the method he used to come here. He found Adrian with the Thunder Swamp Flower.

Adrian was also surprised that Cheng Feng was able to actually collect the Thunder Swamp Flower. After all, he would issue this commission every year, but every year he would receive news of failure. Some S-class wizards even died in the Withered Swamp.

To be honest, Adrian had already given up hope, but he still issued this commission out of habit.

But unexpectedly, this time, it really succeeded!

And there are ten of them!

If he used them sparingly, he wouldn't have to worry about not having enough Thunder Swamp Flowers for about three years!

So, Adrian readily gave the Dragon-Slaying Magic Crystal to Cheng Feng, and even gave him a bottle of potion.

"It is very dangerous to embed the Dragon Slayer Crystal. Many people have tried it, but the probability of failure is over 90%."

Adrian handed the potion to Cheng Feng and said, "I developed this potion. It can increase the success rate of embedding some Dragon Slayer Magic Crystals. I hope you can use it. If you want to sell it, you can sell it as a set. It should increase the price of this Dragon Slayer Magic Crystal a little."

"Why don't you sell it yourself?"

Cheng Feng did not refuse. After taking the potion and the Dragon Slayer Crystal, he asked Adrian.

"I don't have time, and I don't really want to socialize with people."

Adrian smiled and said, "My dream is to become a pharmacist and create a potion that can restore the disabled. Other than that, I have no interest."

Looking at Adrian's creepy smile, Cheng Feng admired him in his heart. This kind of people are very persistent and weird.

But it is precisely because of this kind of people that the world has developed so well.

After bidding farewell to Adrian, Cheng Feng boarded the train back to Magnolia.

In the car, Cheng Feng was rubbing the fist-sized Dragon-Slaying Magic Crystal.

With continuous touch and detection, Cheng Feng discovered that this was a relatively rare space-attribute dragon-slaying magic crystal.

If it had other attributes, Cheng Feng would probably sell it without hesitation in exchange for money to draw cards.

However, the spatial attribute, even if it is just simple spatial movement, is of great help in enhancing Cheng Feng's power system!

So Cheng Feng was thinking whether he should use this Dragon-Slaying Magic Crystal himself.

Every wizard in this world doesn't just know one kind of magic; it all depends on one's own strengths.

For example, Mirajane awakened the receiving magic, but that didn't stop her from learning transformation magic.

Mastering one more kind of magic is a good way to increase your combat power, as long as it does not conflict with your main combat power system.

"Receiving magic is very easy to learn because of my own card game. But for other magic, without this blessing, the learning speed is really too slow, and it is completely incomparable to receiving magic. But the Dragon Slayer Magic Crystal, as long as it is embedded in my body, I can directly use the Dragon Slayer Magic. It is indeed a shortcut to master a kind of magic."

Cheng Feng muttered to himself, and the idea of ​​keeping the Dragon-Slaying Magic Crystal gradually deepened.

As for the possibility of inlay failure, Cheng Feng doesn't have to worry too much.

After all, he has successful examples around him, so he can ask Laxus when the time comes to see if there are any precautions.

……

"Is this the Dragon Slayer Crystal?"

In the Fairy Tail Guild, Cheng Feng, who had already returned, sat there eating and drinking as if he wanted to make up for the food he had not eaten in the past few days.

Everyone in the guild gathered around a table, looking at the Dragon-Slaying Magic Crystal that Cheng Feng brought back, marveling at it.

"Cheng Feng, are you planning to inlay this Dragon Slayer Magic Crystal yourself?"

Makarov looked at Cheng Feng who was eating and asked.

"Correct."

After stuffing a piece of steak into his mouth, Cheng Feng nodded and said, "I have used my magic power to investigate. This Dragon Slayer Magic Crystal is of the Space Element. It can fill in some of my shortcomings in combat. Overall, the benefits outweigh the disadvantages."

"But have you ever considered that if you fail, it may have a certain impact on you."

Makarov pondered: "Have you ever thought about this?"

"I have thought about it, so I plan to ask Laxus for advice and see what I need to pay attention to when embedding the Dragon Slayer Crystal."

Cheng Feng spoke frankly, and Makarov nodded after listening.

Natsu, who had just finished looking at the Dragon Slayer Crystal, said to Cheng Feng, "Cheng Feng, if you embed this, will you become a Dragon Slayer like me?"

"It should be, but the specifics still depend on what the reaction will be after the Dragon Slayer Crystal is embedded."

Cheng Feng opened his mouth, but did not say out loud some of the speculations in his mind.

After dinner, Cheng Feng borrowed some communication tools from Makarov and contacted Laxus who was working.

"Inlaid with Dragon Slayer Crystal?"

The Laxus projection groaned for a moment, then pointed to the lightning scar on his left eye and said, "When I was inlaid, I felt extreme pain, as if my body was being torn apart by the lightning. If I didn't have lightning magic to match it, I don't think I would have lasted long enough for the Dragon Slayer Crystal to merge with me."

"So, it requires a certain level of physical strength and magical compatibility to increase the chances of success, right?"

Cheng Feng looked at Laxus and said.

"That's all I know. For details, I guess you should ask my useless father. He was the one who took charge of the main aspects."

Facing Laxus' words, Cheng Feng nodded.

As for going to find Ivan?

Don't even think about it. Even if Cheng Feng defeats him and then asks him, the other party will probably make things difficult for him.

Therefore, Cheng Feng didn't believe what that person said.

Finally, Cheng Feng contacted Crawford again and asked about the inlay of the Dragon Slayer Demon Crystal.

After Crawford learned about it, he immediately asked Cheng Feng to come to the Magic Council. They have rich inlay experience there, which is enough to increase the success rate to 60%!

Crawford's words reminded Cheng Feng of someone.

Serena possesses eight dragon-slaying crystals!

With the experience of inlaying eight Dragon-Slaying Magic Crystals, the Magic Council is indeed confident enough to help Cheng Feng successfully inlay the Dragon-Slaying Magic Crystals.
