Frustrated, Zheng Jing found a hotel in the city to stay.

In the city lord's mansion just now, the city lord offered to give Zheng Jing 20,000 gold coins to buy the weapons and equipment he brought, but Zheng Jing refused, he was now full of the Tian Huangshi that was not much bigger than an egg, but it was priceless, how could he think of anything else? Besides, there is so much gold, and his Qiankun bag can't hold it.

Tianhuang stone is a rare stone that happened to be produced by the combination of many unique geological conditions, and there is only such a small place on the earth, and although I happened to encounter one here, but there is only such one, the city lord himself said that this is the ancestor did not know where to get it, he has never seen the same stone for so many years, and his own one, because it is a family heirloom, Zheng Jing refused to sell it no matter what he said, and he didn't even agree to let Zheng Jing touch it, and broke Zheng Jing's idea of copying one with the sage's stone.

"Since there is no way to get it by trading, we can only consider other ways. Brother Hei Chao, do you think with your strength can you go all the way to the City Lord's Mansion? Zheng Jing has a calm face, his surname prefers to be a low-key businessman who makes a fortune, if he is not forced to do so, he really doesn't want to make a cameo appearance in such an unskilled profession as a robber.

Brother Hei Chao nodded affirmatively to Zheng Jing, his strong body was hard against demonic beasts like the Fire Skylark, and the guards of the City Lord's Mansion did not put it in his eyes at all.

"Okay, you go out and watch the door for me, don't let people in."

Instructed Brother Hei Chao to help guard him, Zheng Jing was alone in the room and took out the binoculars from the Qiankun bag.

The inn was three stories high, and the room he wanted was on the third floor, and the angle of the window was facing the direction of the City Lord's Mansion.

Through the telescope, Zheng Jing could vaguely see a little bit of the situation in the City Lord's Mansion, the cane inlaid with Tian Huangshi had never left the City Lord's side, and he had to take it with him even to the toilet, and the City Lord basically would not leave the City Lord's Mansion, so it seemed that it was the best choice to grab it directly.

"Hey! Let me in, why are you big black guy holding me back? Is that bad guy doing something shady again? ”

There was a sudden quarrel outside the door, Zheng Jing could hear that the voice was Nina's sister who didn't let him be at peace, and quickly put away the binoculars, this time he was really doing something unseemly.

"Let her in." Zheng Jing opened the door and said to Brother Hei Chao, who was blocking in front of Nina.

"Hmph." Nina has never given Zheng Jing a good face, and as soon as she came in, she pouted and said: "You guy is sneaky all day long, and he doesn't say where he came from, and he always comes up with some strange things, and we saved you once, and you still hide everything from us like this." ”

"Actually, I'm from another world, can you believe it?" Zheng Jing said with a smile.

Nina nodded: "Letter." ”

Zheng Jing was stunned, he was just joking, but he didn't expect to get such an answer.

Nina seemed to take it for granted: "Why don't you believe it? Although I don't know if what you said is true, there is one of the teachings that Lord Ryujin has taught the world - don't limit your eyes to the small space in front of you, there are many different worlds outside the Ryujin Continent. This is what every school book teaches. ”

Zheng Jing didn't expect that there would be such an advanced concept in this world where science and technology civilization are so backward, but there are many such incomprehensible things, and he doesn't care too much.

"Speaking of which, what are you doing here with me? You can't just show me face, right? ”

"Oh, yes." Zheng Jing remembered his business as soon as he mentioned Nina, so he said: "The head of the regiment asked me to come out to sell the demon core, by the way, I asked if you need help, really, I don't know why the head of the regiment is so polite to you." ”

"Sell the core?"

"Yes, in addition to obtaining the magic core of the fire lark on the Red Flame Mountain this time, I also hunted a lot of demonic beasts on the way, and I have a few magic cores in my hands, but these things are useless to us at all, but the magicians like these things very much."

Zheng Jing didn't care about Nina's bad attitude towards him, and hurriedly beckoned her to sit down, and asked like a curious baby, "Can you tell me more about what the magic core is used for?" ”

"What is the purpose of the core, you ask? Well...... Actually, I don't know very well, but I know that those magicians like to have high-level magic cores embedded in their staffs, oh yes, they also need magic cores to power their magic arrays! ”

"Drive the Magic Array...... Sure enough......" Zheng Jing muttered to himself, suddenly raised his head, and continued to ask Nina: "Do you have a magic core in your hand?" Can you give me one? ”

"Are you a magician? What do you want the core to do? Nina said, but still took out an earthy yellow spar and handed it to Zheng Jing.

When Zheng Jing got the magic core, he couldn't wait to ask the terminal in his mind: "Try to convert this thing in my hand into teleportation energy." ”

"Confirmed, low-level energy sources that can be converted are discovered, and the conversion procedure is initiated."

As the voice of the terminal appeared, Zheng Jing quickly felt that the weight of the magic core in his hand was getting lighter, and the color of the spar was also fading at a speed visible to the naked eye.

"The transformation is complete, and this transformation will gain 5 points of teleportation energy." When the spar in his hand became colorless, Zheng Jing received a reminder from the terminal.

The energy in this small piece of magic core is equivalent to 5 large barrels of gasoline, can you believe it!? Zheng Jing was completely shocked, but suddenly found that Nina was glaring at him with anger.

"Hey! What happened to you with my core? Did you know that this stuff is expensive? ”

"Don't worry, I'll just give you the money, or you can sell me all the magic cores on your body." Zheng Jing said disappreciatively.

"You want to buy a magic core?" Nina blinked curiously and looked at Zheng Jing.

"Well, also, do you have anything to do with your mercenary group lately?"

"There must be something, I just finished the task of the city lord, of course I will go to take on other tasks to do, our mercenary group has always been very busy, why do you ask this?"

"Go back and tell your regiment leader for me, just say that I have a task that I need your help with, help me get some magic cores." After a pause, Zheng Jing took out a big money bag and threw it in front of Nina: "Don't worry, I'll pay, look, I have money." ”

Nina turned her head speechlessly and stopped looking at Zheng Jing, saying that this money is just yesterday that you just hacked from us, okay? Are you embarrassed to ask us to do things with this money?

――――――――――――――――――――――――――――――――――――――――――――――――――

The next day, there was another vendor in the square in front of the city lord's mansion.

That seven-star sword is too evil, after slashing the fire lark with that sword last time, Zheng Jing's physical strength has not fully recovered until now, his body is soft, and he usually feels tired after walking a few steps, but he is not an idle person, so he can only find something that does not require physical strength.

Zheng Jing spent 5 gold coins to buy this stall facing the gate of the City Lord's Mansion from a vendor selling pots and pans, and while secretly observing the movements in the City Lord's Mansion, he also made a little money by the way, so that the people of the mercenary group could help him collect more magic cores, but the things he sold were a little more unique.

"Condoms! Condom! Ultra-thin! Super cool! Ultra-safe condoms are only sold for 100 gold coins! What can you buy for 100 gold? I can't drink a bottle of famous wine, and I can't listen to a concert! But buying a condom for 100 gold coins can make you feel at ease and boldly talk to the beautiful maid at home, without worrying about making her belly bigger and being discovered by her wife! Buy a condom for 100 gold coins, and you can have a good time cheating with the lady next door, and you don't have to bear any responsibility! What are you waiting for, sir? Come and buy a condom! ”

The booth in front of Zheng Jing was filled with colorful and various styles, foreheads, condoms, no way, the Qiankun bag had such a small capacity, and the twenty big knives and twenty bicycles took up too much space, resulting in a very tight space, so the remaining limited space Zheng Jing was full of this kind of cute little thing that was small and bullet.
