Mystery Merchant? Yang Yu's eyes lit up, his eyes followed the route he took, and when he reached a corner where there were no monsters, Yang Yu appeared and stood in front of the mysterious merchant.

"Hello!" Yang Yu said to him.

"Dear warrior, is there anything I can do to help you? I'm a merchant walking this battlefield, and I may have what you need. The mysterious merchant glanced up at Yang Yu and said to him familiarly.

This should be an NPC in an online game.

Yang Yu held his forehead and thought helplessly.

"What do you have here?" Yang Yu didn't think about it deeply, and immediately got back to business and asked.

Hearing this, the mysterious merchant immediately opened the package on his body, and saw all kinds of things, including scrolls, maps, weapons, and quaint books, and he said, "These are my goods, but I think the most useful of them to you should be battlefield maps and skill books."

Skill book? Yang Yu noticed this, and a trace of longing rose in his heart at that time, "It's sold like this." ”

"An E-level skill book is a hundred gold coins, a C-level skill book is five hundred gold coins, and a battlefield map is worth a hundred gold coins, if you don't have that kind of gold coins, you can sell me something valuable on you." The mysterious merchant said with a smile.

"That's it!" Yang Yu nodded, killing monsters during this time, in fact, a lot of coins were exploded, and I thought it was useless at first, but fortunately, I still put it away, and these scattered ones add up to more than three hundred gold coins, but if you buy a skill book, it is still two hundred.

"Sir, do you accept the monster's materials?" Yang Yu asked.

"Of course, I will accept everything that is valuable." The mysterious merchant said, his expression was a little surprised, Yang Yu was very light, it seemed that he didn't have anything with him, he would have materials on him?

"That's good! How much do you think these things are worth? Yang Yu breathed a sigh of relief when he heard this. After saying that, he took out nearly a cubic meter of things from the storage ring, all of which were just obtained body materials from those monsters, but anything he thought might be used, he cut them all and put them in the storage ring, anyway, the space of the ring was empty.

There was a storage ring. The mysterious merchant looked at Yang Yu in surprise, the strength of the person in front of him was not very strong, but he had a storage ring, which was really incomprehensible.

Although he was surprised in his heart, the mysterious merchant still froze, looked at the things that Yang Yu took out one by one, and after a while, he nodded and said, "These things are worth five hundred and twenty gold coins. Adventurers, do you need to trade now? ”

"Of course!" Yang Yu did not hesitate.

The deal was reached, and the mysterious merchant gave Yang Yu five hundred and twenty gold coins, and the materials on the ground were also taken away by the mysterious merchant.

"Then I now want a C-level skill book and a battlefield map." Yang Yu's heart hurts, this money has not been covered yet, and he is going to spend it again.

"Yes, esteemed adventurer." The mysterious merchant laughed, he had met several people in the past few days, but it was indeed rare for him to be as generous as Yang Yu.

After getting the battlefield map and skill book, Yang Yu smiled happily in his heart, and after roughly rubbing it around, he put it back into the storage ring.

However, at this moment, the mysterious merchant's lowered gaze flickered, and he asked, "Respected adventurer, do you have a king-level insect crystal on your body?"

King-level insect crystal? Yang Yu was stunned when he heard this, and in an instant, he thought of the worm crystal that the Nine Tails gave him.

"That's what you're talking about?" Yang Yu took out the worm crystal.

"Yes, yes, that's it, I've wanted king-level insect crystals for a long time, I don't know if you're interested in trading?" The mysterious merchant laughed, as if he had really found something amazing, and the wrinkles on his face widened.

"What is a king-level insect crystal, and how do you want to trade it?" Yang Yu raised his eyebrows, he didn't know the value of this thing, but he didn't want to be cheated.

Hearing this, the mysterious merchant patiently explained: "The king-level insect crystal is more crystal clear and transparent than the ordinary insect crystal, not only is it larger than the ordinary insect crystal, but the energy contained in it is also much purer than the ordinary one. Moreover, insect crystals are widely used, in addition to replenishing energy, they can also refine medicine refining tools, etc., and the advancement of pets is also essential. ”

That's right! Yang Yu touched his chin, this information is quite valuable.

"I can exchange it with you with a detector, this thing can accurately detect creatures within thirty meters, and with the battlefield map, it can even roughly detect a range of more than a kilometer or even longer, and the value may be greater for you than the king-level insect crystal." The mysterious merchant said, pulling out a round metal object from his bosom.

Hearing the function of the detector, Yang Yu immediately understood the power of this thing, not to mention a king-level insect crystal, it was worth it plus the insect crystal that was swallowed by the nine tails, Yang Yu immediately made a decision and said, "Deal."

Hearing this, the mysterious merchant laughed, getting the king-level insect crystal obviously made him feel a lot better, he said: "Happy cooperation with you, I'm telling you a news, there will be a worm tide in half a month, you have to be prepared, it's a super terrifying thing, if you want to be really safe, move to the second-level battlefield."

With that, the mysterious merchant strode away, unafraid of the monsters.

Yang Yu watched him leave, and secretly thought in his heart, insect tide? It seems terrifying.

Secretly writing down this matter, Yang Yu looked at his skill book with a torch in his eyes, and without any hesitation, he took out the yellowed ancient book and opened it immediately.

swish

As soon as the cover of the skill book was opened, a dazzling red light flashed out, and the entire skill book immediately turned into a ball of light and shot into Yang Yu's head.

Fire escape, the art of fireball.

Turns chakra into flames and shoots forward, dealing massive area of effect damage.

Yang Yu only felt that there were a lot of things in his mind, all of which were about the way to cast the Hao Fireball technique, and the content was so obscure that it made his head hurt.

It seems that this world is still different from online games.,Yang Yu originally thought that after reading this skill book, he would be able to master it.,In the future, you can use it to play online games like that.,I didn't expect this skill to be learned by myself.。 It seems that there is no such thing as a free lunch in this world.

Yang Yu's mind was active, and after a while, he basically figured out the use of the Hao Fireball Technique, but if it was to be used perfectly, it would take a little time to explore.

Well, it's time to go and kill.

Yang Yu shook his heavy head and looked at the river not far away, a cruel smile appeared on his face.

Ye Qi, you wait.
