Chengbei Bridge is more like a civilian area, with an area of two or three miles, and there are at least 30,000 people living here, most of whom are ordinary people. They are now more cooperating with the soldiers to transform the city, and get the expenses of living in the city from the academy, and they can only get a dozen copper coins a day.

Cheng Hua has been living in Chengbeiqiao for a month, and he has been moved here since the arrival of visitors from other worlds, living in a former empty house and working as a coolie every day. A month ago, he was a town dweller, living his white-collar life at work, but now he can only sweat and work every day. Listening to the news from the academy, when the city is almost renovated, they will be separated from these coolies and given to those heroes who have meritorious service and the academy, so that they can go to the wilderness and reclaim the land.

"Phew, this dog's day!" Cheng Hua chewed on the unpalatable dry food from the other world, and missed the vegetables and rice steamed buns in the past.

"Hello, excuse me, what's going on in the underground exchange!" Wei Si saw a sloppy man sitting on the side of the road, and asked for directions.

"I don't know!" Cheng Hua raised his eyes to look at Wei Siyuan, then drooped down and replied impatiently.

Wei Siyuan touched his nose and didn't ink, and replied with a thank you, ready to ask someone again. Along the way, no one knew where the underground exchange was.

"This soldier dares to lie to me! I'm so angry, my 5 silver coins!" Wei Siyuan became more and more angry the more he thought about it.

At this time, he glanced at a man in his 30s, who was neatly dressed and neat, without the slightest sloppiness of the other residents.

"Hello!" Wei Siyuan chased after him, blocking the man's way.

"What do you want to do?" The man was very vigilant, and when he saw Wei Siyuan blocking his way, he took a step back without leaving a trace, and looked at Wei Siyuan carefully with his eyes, faintly defensive.

"I want to inquire where the underground exchange on this side of the Chengbei Bridge is?" As he spoke, Wei Siyuan was also secretly looking at this man, secretly guessing in his heart that this person was probably an Earth Talent.

"Are you a gifted?" the man asked rhetorically, looking into Wei Siyuan's eyes. "This pupil is black, it should be an earthling!" the man thought to himself.

"Yes! I want to find the way! I will get the materials and go to the underground exchange to buy them!"

"Cheng! you follow me!" The man was obviously relieved after confirming that Wei Siyuan was an Earth Talent, and his defensive posture slowly took off. led Wei Siyuan to turn around, and there were fewer and fewer people left and right, and when he arrived at the mouth of an alley, he knocked on the door of a house. Wei Siyuan looked very carefully, and knocked 4 times in a row, with two heavy and two light frequencies. Soon, the door opened from the inside, and the man beckoned Wei Siyuan to enter. After the entrance, there is a section of steps that turn down, about 100 meters, and there is still a door at the bottom of the steps, and there are also guards, and the gatekeeper of the first gate needs to go down to check the secret words before it can be opened.

When Wei Siyuan stepped into the second door, Wei Siyuan found that there was a hole inside, similar to an ancient bazaar, from the street where the entrance was introduced to another street, the two streets converged into a crossroads, and low shops and workshops were built on both sides of the road, and these shops and workshops were opened by talented people who joined the academy. Here, they buy materials, process them, sell the props they make, and earn money from the free-born.

"Thank you, big brother!" Wei Siyuan arrived at the place, his mood became happy, and he hurriedly thanked the man who led the way.

"It's okay! they're all Earth Talented, and it's right to help them!" the man bowed and left.

Wei Siyuan looked at this underground market and couldn't help but marvel. It's not that the bazaar building is beautiful, but the bazaar is hidden deep underground, and he can't see the top of the bazaar, and he doesn't know where the light source is coming from.

Wei Siyuan walked into a shop at random, and a guy at the door of the store immediately greeted him, "Hello!

"Hello, I'll take a look!" Wei Siyuan snorted, he only had 1 silver coin left on him, and he didn't know the purchasing power of the silver coin, so he simply walked around casually, just open his eyes and have a long insight.

"Then let me tell you about the sorting of goods in our shop!" the man cleared his throat and continued, "Our shop now specializes in meditation potions and recipes, as well as materials and custom weapons. ”

"You can tell you everything!" Wei Siyuan listened to the words that popped out of the guy's mouth and faintly felt like he was in the game, but he couldn't guess it, it was still necessary to listen to the guy's careful explanation.

"Meditation elixirs can mainly help martial artists and magicians speed up the cultivation of magic techniques, the quality is from low to high, and the higher the quality, the better the effect!

"The recipes are divided by rank, and at present, the store only sells low-level recipes, and there are both martial artists and magicians!"

"As the name suggests, the materials obtained in the field can be sold here, and we will buy these materials at a price 20% higher than the exchange!"

"Custom weapons are to meet the needs of some customers, and some parts such as claws, teeth, and bones of beasts are processed into weapons according to their needs. ”

"Are custom-made weapons sharper than the usual iron?"

"That's for sure!" the guy smiled and explained, "Because the material absorbs the aura of heaven and earth, it is naturally sharper than mortal iron!

"It seems that this is similar to a game!" Wei Siyuan thought in his heart, but said, "What about the price?"

"Meditation Elixir is a low-grade 1 silver coin and medium 10 silver coins. In the case of magic, the martial artist has 1 gold, the mage has 2 gold, and the material depends on the quality of the cut, and the custom weapon also depends on the difficulty of customizing the weapon, generally ranging from 10 silver coins to 2 gold. ”

Listening to the guy's introduction, Wei Siyuan couldn't help but be a little dumbfounded, a low-grade medicine was so expensive. When he just glanced at the store, he saw a potion, a small one, with an estimated capacity of less than 80 ml, and it actually offered 1 silver coin, which was a money grab!

"Ahem! Okay then! You go and entertain other customers! I'll take a look at it and call you when I'm ready!"

"Okay, then you can choose slowly!" The guy probably saw that Wei Siyuan was shy, and happily beckoned the others to go, leaving Wei Siyuan alone to pick in place.

Wei Siyuan looked left and right, and the medicines were all the same. Similar to a test tube, the test tube is sky blue with a small plug plugged in, and if it weren't for the fact that the sky blue looks so pure, the potion would not look remarkable at all. Look at those tricks again, they are all fixed, give a cover, you can't open it at all, Wei Siyuan looked at the tricks that the guy took for him from the back room after he bought the tricks, and they didn't take it directly from the shelf at all.

After watching it for a long time, Wei Siyuan felt poorer the more he looked at it, and he was about to leave, when he was suddenly stopped by his buddy Jian.

"Hello, we have a new medium-quality meditation potion on the shelves, you don't need to take a look at it!"

"Medium quality?" Wei Siyuan was stunned for a moment, and saw a person coming out of the back room, holding a glass cabinet, and in the glass cabinet was a purer sky-blue meditation potion, Wei Siyuan could feel the air flow in his body!

"Gotta get it!" Wei Siyuan was tightly attracted by the sky-blue elixir, and the elixir seemed to have a magical power, making every cell in Wei Siyuan's body jump and cheer.

"I must get that potion!" Wei Siyuan said silently in his heart.

Wei Siyuan looked at it for a long time, and it wasn't until the potion was bought that he withdrew his gaze and made up his mind to go to the wild to obtain materials. Wei Siyuan obtained the information on most of the field materials from the store, as well as the knowledge of the heavenly materials and earthly treasures that various low-level martial artists and magicians could use.
