"May I ask how the seniors can improve the strength of these elite-level demon beasts?" Xiao Han asked humbly, Xiao Han knew that these NPCs were all old monsters who had lived for hundreds of years, and they knew everything in the sky and on the ground, maybe they could really improve the strength of elite-level demon beasts through some special methods.

"In the cultivation realm and the immortal realm, pets are also a manifestation of a person's strength, and naturally there will be many people studying how to improve the strength of pets. Elite-level demon beasts are spirit beasts cultivated between heaven and earth, and they collect the essence of heaven and earth through cultivation to improve their strength. Once they become the pets of cultivators, they lose the opportunity to cultivate, but fortunately, they can absorb the aura on some rare herbs and pills to improve their strength. The old man patiently explained.

"That means it's okay to feed them more herbs or pills?" Xiao Han asked.

"Yes and no. Elite-level demon beasts also have certain requirements for medicinal herbs. Earth-level demon beasts need heaven-level herbs or pills to improve their strength, while heaven-level demon beasts need herbs or pills above the spirit level, and it is useless to eat herbs of the same level. The old man explained, "Of course, the higher the grade of the herb, the more obvious the effect on the demon beast. If you can put things like fairy stones in the pet space, you can also improve the strength of elite-level demon beasts. ”

"Immortal stones?" Xiao Han was stunned for a moment, "I don't know what the fairy stone is?" ”

"The immortal stone is the item circulating in the immortal world, and the strength of the immortal qi contained in the immortal stone determines the quality of a immortal stone. The aura contained in the immortal stone is of great help to the elite-level demon beasts, the price of a low-grade immortal stone is about five million gold coins, and a medium-grade immortal stone is about fifty million gold coins, and the price of a higher grade is more expensive. The old man patiently explained to Xiao Han, but Xiao Han beat a drum in his heart, listening to what the old man said, the things in the mysterious shop were simply untouchable, and some things were taken out casually for millions of gold coins, and the price was too terrifying.

"I wonder how much the immortal stone helps the elite-level demon beasts?" Xiao Han asked.

"The aura gathered on a low-grade immortal stone can make a ground-level elite-level demon beast advance, and the aura on the immortal stone is more refined than the ordinary aura, which has a great effect on the future growth of the elite-level demon beast. Of course, it also takes time to absorb the aura on these immortal stones, and without ten days and half a month, it is difficult for elite-level demon beasts to completely absorb the aura on the immortal stones. The old man explained.

Do you want to buy immortal stones to help those elite-level demon beasts on your body advance? Xiao Han felt that his money was too little, and he hated less money when it was used, if he had a city, Xiao Han might not be so hesitant.

Xiao Han smiled bitterly, although his monthly income was hundreds of millions of gold coins, he didn't know if it was worth buying these immortal stones.

Fluttershy grabbed Xiao Han's hand and whispered, "Although I know you won't spend my money, I still have about 100 million gold coins, so if you want to use it, just use it." ”

Mai Aya on the side looked at Xiao Han firmly, if Xiao Han had a place where she needed Mai Aya, she would not hesitate.

"I have enough gold for me. Don't forget that I still have a 7% stake in Taiyi City. Xiao Han smiled slightly, and sent a message to Duzun, asking him to transfer the previous money to his account. Within a few minutes, Xiao Han's account had an additional 50 million gold coins. "Senpai, can you introduce me to something else?"

"Just ask." The old man nodded, disapproving, young people are always curious about things they don't know, and people often come in and ask what these things do, although there are not many people who really want to buy them, but he still patiently explains to everyone, after all, it is quite lonely to stay here every day, it is better to chat with these young people to relieve boredom.

"What herbs and pills are sold here?" Xiao Han asked, he needed too many things, but too little money, so Xiao Han had to seriously consider what he should buy.

The old man smiled and said: "Most of the herbs and pills I sell here are immortal-level herbs and pills, none of them are mortal items, of course, the price of these things is extremely expensive, the price of an immortal-level lower-grade medicinal herb is about 100 million gold coins, and the price of an immortal-level lower-grade pill is about 200 million gold coins." ”

Xiao Han was speechless, oh my God, this price is really terrifying, and the server is simply grabbing money.

"What about mechanical gadgets? What is it? Xiao Han asked suspiciously, he had never heard of this thing before.

The old man's eyes lit up, and he said with a smile: "That's my own little invention, such as this wood spider." The old man pulls a spider out of his pocket, and Fluttershy and Maiya scream in horror, the spider is so realistic, the size of a palm, with red eyes and a squeaky sound. The eyes kept turning, and the red light kept flashing, as if it were alive. Fluttershy and Maiya look at it for a long time before they realize that the spider is made of wood, and they are relieved to see that the wood spider is also quite cute, and they can't help but tease it.

"It's like the real thing."

"Grandpa, you're doing so well."

The old man smiled smugly: "Of course, but don't underestimate this wood spider, it's very useful." It has a small self-detonation spell installed in its head, and with a small amount of true power, it can smash the wooden spider to the designated location, and then launch a self-detonation. Its power is much more powerful than the ten great divine thunders of your human realm. ”

I didn't expect such a little wooden spider to have such a use, Xiao Han listened carefully to every word of the old man, but the last sentence of the old man attracted Xiao Han's attention, the old man used the word 'your human world', isn't the old man a person in the world, and many of the things sold by the old man are immortal treasures, is this old man a fairy family? Xiao Han overheard such a secret, and he was very puzzled, since he was from the immortal family, why didn't he stay in the immortal realm and appear in this Xuanyuan City? And he lives in Xuanyuan City, it is impossible for the Xuanyuan City Lord not to know that the old man lives here, so what is their relationship?

The old man didn't know that Xiao Han was already guessing his identity at this time, and continued with great interest: "There is also this iron silver snake, its whole body is made of arctic cold iron, no weapon in the human world can cut it off, it has a life charm hidden in its body, it has a snake-like spirit surname, and its teeth are made of special cold iron, and there is a small hole in it, which can be used to transmit letterheads. ”

Xiao Han couldn't laugh or cry, seeing that this silver krait was so similar, he didn't expect it to be used to send letters, players can communicate with each other at will, and they don't need this thing at all, this silver krait is really a chicken rib compared to the wood spider.

"And this wooden flying beetle, which has the same function as the wood spider, but with the ability to fly. And this 、、、、、、" The old man spoke with great interest, Xiao Han didn't listen to it very interestingly, but Fluttershy and Mai Aya seemed very interested, and the old man saw that someone was listening to him, and he was even more excited, and took out all the things he pressed at the bottom of the box, but in Xiao Han's opinion, except for the wooden spider and the wooden flying beetle, the rest was really useless.

"Senior, what is the price of your wooden flying beetle and wood spider?" Xiao Han asked, he couldn't help but interrupt the old man's chatter, Xiao Han didn't know how many things he hadn't taken out, if he listened to him explain them one by one, he didn't know when it would be.

The old man looked at Xiao Han happily: "What's the matter, you have taken a fancy to these gadgets of mine?" You're the first to be interested in these little things of mine, and I'll count you cheaper, 500,000 gold coins each. ”

Xiao Han almost didn't squirt out, cheaper, 500,000 gold coins each? Xiao Han's face was strange, but after thinking about it, it was indeed worth the price. This thing is the equivalent of a remote-controlled bomb, and it will be very useful when used well. "Give me five wooden flying beetles." Xiao Han compared the flying beetle and the wood spider, it was obvious that the flying beetle was more practical, and Xiao Han paid two and a half million gold coins.

In order to prevent the old man from continuing to explain his gadgets, Xiao Han hurriedly asked, "What does that merit mean by exchanging immortal wishes?" What is the Immortal Wishing Power? ”

The old man shook his head with a smile and said, "This is a secret of the fairy world, and you must not tell anyone in the mortal world." However, the power of the immortal family is beneficial and harmless to individuals, especially to people in the mortal world. ”

"How do I redeem that?" Xiao Han couldn't help but ask, he still had thirty-five thousand merits on his body, and he didn't know if he should exchange it for immortal wishing power.

"A little merit is exchanged for a little immortal wishing power, young man, you still have thirty-five thousand merits on you, the old man suggests that you exchange all of them for immortal wishing power, as for whether you are willing or not, you need to consider it yourself." The old man had a smile on his face.

Xiao Han thought about it, this old man doesn't seem to be a bad person, and merit is not a precious thing, as long as he saves some people or kills some red names, he can get it, as for what is the use of this immortal family's wishing power, he has to study it himself, it's just a big deal to lose some merit, and let it go. "Then please ask my seniors to help me exchange all of them for immortal wishing power."

The old man bowed slightly, and a white light lit up from his palm, gradually disappearing into Xiao Han's body, Xiao Han felt warm all over his body, and his whole body was extremely comfortable.

System: You have gained 35,700 points of Immortal Wish Power, and you have lost 35,700 points of merit.
