Upon seeing the billboard, Su Bai's eyes lit up instantly.

  As a Beast Tamer, Su Bai's main combat strength relied on his tamed beasts.

  The Little Tortoise possessed the Basalt Bloodline of a sacred beast. As long as it could grow, Su Bai would have the foundation to survive and thrive in this catastrophe.

  The Little Tortoise's evolution depended on eating, and its enormous appetite was a money burner.

  How to earn money to feed the Little Tortoise was the biggest challenge Su Bai faced at the moment.

  This advertisement was a godsend!

  A feasible pn had already formed in Su Bai's mind.

  However, at this moment, the Little Tortoise hiding in the Beast Taming Space inexplicably felt a chill down its spine, as if someone with ill intentions was thinking about it.

  (Note: The Beast Tamer system comes with a Beast Taming Space, currently only 100 cubic meters in size, which will expand as the host's strength increases.)

  ***

  Time always flies by quickly, and in the blink of an eye, a day had passed.

  After school in the afternoon, Su Bai hurried home and released the Little Tortoise from his Beast Taming Space.

  No need for words.

  He grabbed the still-confused Little Tortoise's front paw, picked up a kitchen knife, and sshed down.

  But who would have thought that the Little Tortoise's front paw remained completely unscathed!

  "So tough?!"

  If this knife had been used on human skin, it would have long been torn open, with blood gushing out like a fountain.

  So Su Bai increased his strength, using all his might to chop down, barely managing to cut a small wound on the Little Tortoise's front paw.

  "Roar!"

  The Little Tortoise howled in pain.

  Su Bai quickly took out a prepared small test tube and collected a few drops of the Little Tortoise's blood.

  He originally wanted to collect more, but by this time, the Little Tortoise's wound had already begun to heal itself, no longer bleeding.

  This self-healing ability was quite impressive!

  The Little Tortoise, inexplicably sshed, stared at Su Bai with its small beady eyes, terrified and unable to understand why its master would harm it.

  Su Bai put the kitchen knife back in the kitchen, rolled his eyes at the Little Tortoise's fearful gaze, and said:"I'm doing this to earn money to feed you. Do you think you can just eat for free? Dream on!"

  Su Bai couldn't be bothered with the Little Tortoise's grievances.

  He grabbed its little tail and tossed it back into the Beast Taming Space.

  Then he searched around the house and found his dad's usual bck coat, a baseball cap, and a mask.

  About ten minutes ter, Su Bai stood in front of the mirror, took a careful look, and nodded in satisfaction.

  With this disguise, as long as he lowered his voice, no one who wasn't very familiar with him would recognize him.

  Su Bai wasn't doing this without reason. Exotic beast blood was an essential material for making various martial artist healing and training potions and was a strategic resource necessary for martial artists and the military.

  Even the most basic and low-level exotic beast blood could attract a lot of unnecessary trouble in this chaotic world invaded by the Myriad Races.

  Although the military hadn't completely controlled these resources, and there were private manufacturers and buyers of materials, it was still wise to be cautious.

  He hadn't officially entered the Martial Academy yet and didn't have a very secure identity.

  Any unnecessary trouble should be avoided if possible.

  Once prepared, Su Bai headed out.

  ***

  Not long after, Su Bai arrived at the address indicated on the billboard.

  Hiding in a corner where no one noticed, he observed the small shop.

  The shop was quite shabby, a three-story building that looked quite old, with only an iron sign at the entrance.

  "Purchasing various raw materials, selling essential martial artist potions, discounted prices."

  After confirming the address, Su Bai didn't enter immediately.

  Instead, he observed for a while longer, and after finding nothing suspicious, he finally walked toward the shop.

  As soon as he entered, a strange but not unpleasant smell greeted him.

  The shop owner was an old man with white hair, half-asleep listening to the radio. Upon hearing footsteps, he knew business had arrived.

  The old man quickly got up, squinting his eyes and smiling as he sized up the customer.

  "Friend, are you here to sell or buy something?"

  Su Bai gnced at the old man, took out the test tube containing three drops of turtle blood from his pocket, and handed it to the old man, replying in a deliberately lowered voice:

  "I'm here to sell exotic beast blood. Name your price!"

  The old man took the test tube from Su Bai, opened the cap, and sniffed it. A faint fragrance wafted from the test tube, startling the old man.

  This exotic beast blood was no ordinary thing!

  Although it was just basic-grade exotic beast blood, the fragrance alone was something no ordinary exotic beast could possess. It was definitely good stuff!

  Since the Myriad Races invasion, Earth's spiritual energy had revived, and not only humans but animals, insects, and pnts also had a chance to mutate.

  Scientists directly referred to non-human mutated species as exotic beasts.

  The degree of mutation varied greatly, with some being strong and others weak.

  For example, in the Sahara Desert, a mutated giant lizard grew wings and became a fire-type dragon, its strength comparable to a Gold Tier beast among the Myriad Races. Its breath could turn dozens of miles of desert into a fiery hell, making it one of the strongest known mutated beasts on Earth.

  If a powerful exotic beast had offspring, there was a high probability that they would also have the potential to grow into high-level exotic beasts.

  Such specially mutated exotic beasts or their offspring, although only basic-grade, contained energy in their blood far exceeding the same grade and were known as rare exotic beast blood.

  Rare exotic beast blood was often the best material for making body-strengthening, blood-replenishing, and healing potions, significantly enhancing the efficacy of the medicine.

  Especially basic-grade rare exotic beast blood was the best medicine for martial artists to y a foundation, highly sought after by martial artist families focused on nurturing their descendants.

  The old man concluded that the exotic beast blood Su Bai was selling was rare exotic beast blood!

  He just didn't know where this guest, who was concealing his identity, had obtained it.

  This stuff wasn't easy to come by, usually relying on luck or being obtained by high-tier martial artists.

  However, the old man didn't delve into it. He was in business, only caring about profit, not the source of the goods!

  But as for the price... The old man pretended to scrutinize the blood, while in reality, he was already calcuting how to lower the price.

  After a while, the old man shook his head and said, "Young friend, this is basic-grade exotic beast blood. I'll buy it from you at the market price of one thousand yuan."

  Su Bai sneered inwardly, not bothering to argue.

  He picked up the test tube and turned to leave.

  The old man was stunned by his decisiveness.

  It seemed he was dealing with someone knowledgeable.

  The old man quickly came out from behind the counter, smiling as he led Su Bai back to a seat in the shop.

  "Young friend, don't be so hasty."

  "I hope you can be sincere," Su Bai replied briefly, not wanting to say much.

  Seeing Su Bai's confident demeanor, the old man hesitated for a moment and then held up one finger.

  Su Bai nodded and said, "Alright, ten thousand it is."

  Pfft!

  The old man almost spat out a mouthful of blood. He meant one thousand yuan, but Su Bai's face was so thick!

  Three drops for ten thousand yuan, did he think it was Bronze Tier exotic beast blood?!

  He really dared to ask!

  The old man took a deep breath, slowly exhaled, and calmed his anger before saying:

  "Friend, you really like to joke. Even if this basic-grade exotic beast blood is rare, it can only sell for a maximum of one thousand yuan! I'm offering one thousand yuan, which is already very sincere.

  If you don't want to sell, I won't insist."

  If it weren't for the old man's eyes constantly fixed on the test tube in Su Bai's hand while he spoke, Su Bai might have believed his nonsense.

  "In that case, there's nothing to discuss. You truly ck sincerity."

  With that, Su Bai continued to get up and leave. After all, the turtle blood was in his hands, and whether to sell it or not was up to him. Su Bai was sure that one thousand yuan was not the real price of the turtle blood!

  "Young... young friend, we can negotiate if the price isn't right..."

  The old man, seeing Su Bai's unyielding attitude, was almost driven to curse.

  This person was difficult to deal with, but the thing was worth far more than one thousand yuan, so there was room for negotiation.

  This time, the old man pondered for a long time before slowly saying:

  "Alright, I'll be honest with you. Although this exotic beast blood is basic-grade, it should come from a rare exotic beast. How about this, I'll double the price to two thousand yuan.

  If young friend still doesn't want to sell, then there's nothing I can do! I've been very sincere."

  Seeing the old man's gritted teeth, Su Bai pondered for a moment. It seemed that two thousand yuan was indeed close to the shopkeeper's expectation.

  Honestly, Su Bai wasn't entirely sure of the exact market price, but he understood business. Having lived two lives, he had seen many cunning merchants.

  This was just haggling.

  Su Bai still didn't relent, continuing to probe:

  "Two thousand? The st shop offered me two thousand eight hundred, and I didn't sell. Why should I sell to you for two thousand? If you can offer more than three thousand yuan, I'll consider it!"

  This statement truly struck a chord with the old man.

  In the entire county, the number of alchemists wasn't small. A top-grade basic body-strengthening potion could help someone quickly transition from a basic martial artist to a Bronze Tier martial artist.

  Its value far exceeded the imagination of ordinary people.

  Not to mention the profit, the most important thing was that selling such rare materials could also earn the friendship of some martial artist families.

  Finally, the old man gritted his teeth and decided to buy the exotic beast blood: "Alright, three thousand it is! Not a penny more!"

  Seeing the old man's gritted teeth, Su Bai knew this was probably his limit.

  Without further ado, he proceeded with the transaction.

  The three thousand yuan far exceeded Su Bai's initial expectations.

  In the end, Su Bai handed over the turtle blood to the old man and received three thousand yuan in cash.

  Just as Su Bai was about to step out the door, the old man quickly said, "Young friend, if you have more of this rare exotic beast blood in the future, you can come directly to me!"

  ***

  After leaving the pharmacy, Su Bai looked at the fiery sunset in the sky, filled with emotion.

  He hadn't expected three drops of turtle blood to sell for such a high price. Earning money in this era didn't seem so difficult.

  With this income, the pressure of feeding the Little Tortoise would be greatly reduced. Three thousand yuan could buy a lot of turtle food!

  The evening breeze brushed against Su Bai's cheeks, and before he knew it, even his steps became lighter.

  ***

  "Humans use sand, trying to mold the Tower of Babel from their dreams, willing to pay any price for greed~"

  The crisp and pleasant ringtone sounded.

  Su Bai picked up his phone and saw it was a call from his head teacher.

  "Hello, Su Bai, tomorrow the college entrance exam results will be announced, and you'll need to decide whether to apply to the Martial Academy or the Academy of Arts. Don't be te!"

  "Okay, I got it."

  He responded simply and hung up.

  His heart, however, was inexplicably stirred.

  Tomorrow was a significant turning point in his life.

  While Su Bai was still dreaming about the future, the Little Tortoise in the Beast Taming Space seemed to sense something. It suddenly raised its head, its eyes vigint, and let out a series of angry roars.

  Su Bai also suddenly felt a chill down his spine, and a warning panel from the system appeared before his eyes.

  [Warning! Warning!]

  [Three humans harbor great malice toward the host and are currently within ten meters of the host. Please remain vigint.]
