Everyone's on a time-travel adventure! I'm raising city beasts in a post-apocalyptic world

Luo Xiaoxiao didn't buy it at all. She put her hands on her hips and stared straight at Master Lin: "You stinky Taoist, do you have any conscience? Was that for me to absorb? Was it for me to quickly recover my spiritual energy so I could build the next one? Is that what you call payment? Who pays by giving a bunch of grass cakes that will make their stomach hurt so much they'll roll on the ground? I want snacks, I don't care, I'm so poor all I have left are grass cakes, you have to buy me some, or I'll go on strike!"

The elderly man wearing sunglasses was silent for a few seconds, then said, "Okay, I'll buy it for you."

Luo Xiaoxiao hadn't expected the old man to agree so readily. He was usually so stingy when she asked him for something. She opened her mouth but swallowed back the words "You old blind man," and whispered, "That's more like it..."

The old man faced Lin Feng, but his sunglasses obscured his expression.

"Young friend, you must be a beast tamer. I'm the captain of this caravan; just call me Old Chen. My awakened ability is danger perception, and my profession is a guide. That child is still young. Do you know how much material we need for these off-road vehicles?"

Lin Feng shook his head. He was more concerned about whether the old man had mentioned "profession" earlier. What was a profession? This was something he didn't understand, but he didn't rush to ask. Instead, he continued to listen.

The old man continued, "Building one of our fleet's off-road vehicles requires no less than 10 tons of high-quality iron ore, plus one level 3 ghost crystal as material. But that's just the material cost. Building such a small vehicle consumes a lot of spiritual energy and mental power. She'll need at least two more level 3 ghost crystals to recover her spiritual energy. So the cost alone is already three level 3 ghost crystals and 10 tons of iron ore. As for the manufacturing fee..."

He held up one finger: "We'll only charge you one level 3 Ghost Crystal as a fee, that's not too much to ask, is it? Of course, if you don't have a Ghost Crystal, you can use other supplies of equal value to pay, like rice, flour, cooking oil, snacks, medicine, gasoline... anything goes."

Lin Feng and Guo Yi both gasped, exchanged a glance, and instantly gave up.

Guo Yi's eyes twitched. They did the math in their minds: a Level 3 Mystic Crystal, and the entire convoy didn't have a single one. The other side was actually using it to build vehicles. It was really extravagant, and the cost-effectiveness was too low.

Lin Feng shook his head at Old Chen: "No need. You know I'm a beast tamer and I live in a villa. I don't really need a car."

Guo Yi also shook his head: "I'd rather go to villages or towns to look for scrapped vehicles. It's not like we have to build them from scratch."

Old Chen was visibly taken aback, his expression almost faltering: "You...aren't you going to try and negotiate the price?"

Lin Feng and Guo Yi shook their heads at the same time.

"No!"

The atmosphere suddenly froze. Luo Xiaoxiao stomped her foot beside her: "Old blind man, now look what's happened! They don't want it anymore, my snacks are gone, I'm not finished with you..."

Seeing her puffed-up face, Lin Feng put the snacks in his hands into Seruo's arms and said, "Little girl, I won't order the car. Consider these snacks a gift from me."

Luo Xiaoxiao was stunned. She looked at the snacks in her arms and then looked up at Lin Feng. She didn't realize that Lin Feng would give them to her. Normally, it was considered kind of someone if no one tricked her out of anything.

She clutched the snacks to her chest, looking at Lin Feng warily. "You...you don't have any other intentions, do you?"

Lin Feng smiled and said, "Just kidding. I just felt sorry for you, so I gave you a few packs. Come and ask me for more when you're done. I really have a lot at home, I'm not kidding you."

After saying that, Lin Feng turned around and waved to Guo Yi, "Let's go. We've already mined quite a bit of iron ore. Let's go discuss how to add two more cargo boxes for me."

The two had only taken a few steps when Old Chen's voice came from behind: "Young friend, please wait!"

Lin Feng turned around: "What is it?"

Old Chen stepped closer and said, "I won't hide it anymore. There's something else we'd like to discuss with you. I see that your miners are quite efficient. Are you selling them? Our convoy is also looking to buy a batch for mining."

Lin Feng hadn't expected them to make this request, so he asked, "What can you offer?"

Old Chen: "What do you want?"

Lin Feng: "Vegetable seeds and fruit seeds are both fine."

Old Chen fell silent, then said somewhat embarrassedly, "I really don't have that!"

Lin Feng: "So what do you have? Don't tell me you only have carts and grass cakes. I found out this morning that gray-faced grass is everywhere around here."

Old Chen briefly recounted how they had traveled through time. There were more than just this many people; tens of thousands of them had simultaneously traveled through a ruin. He happened to land on a broken altar and awakened his danger perception ability upon arriving. There were many strange creatures around them, chasing and killing the group, seemingly intentionally driving everyone towards the altar.

The crowd ran frantically toward the altar, leaving a trail of corpses on the plaza around it. Blood soaked the mysterious patterns around the altar. Then, the altar suddenly activated. Of the more than a thousand people who were originally alive, only five survived after the altar was activated. These five were the Awakened Ones, who also gained professions and greatly increased their strength.

The others were all sacrificed and swallowed by the altar. They fought their way out of the encirclement, gathering many survivors along the way, and finally arrived here.

"So, let alone seeds, we can only rely on these grass cakes for food. If we hadn't hunted a lot of mutated creatures and survived on these grass cakes along the way, we would have starved to death on the road long ago."

Lin Feng was already planning when to go and take a look at the altar the old man had mentioned. He wanted to know how it was related to the Life Altar, the core ability of the Tree of Life.

Lin Feng already knew what he wanted from them. Since he had fought his way out of the strange encirclement, he said, "You must have quite a few monster crystals, right? How about this, I'll take a loss: one black monster, one level 4 monster crystal, or 15 level 3 monster crystals."

Old Chen shook his head: "Impossible, it's not worth that price. A level 4 Mystic Crystal is out of the question, I don't even have one..."

Lin Feng panicked: "How is it not worth it? Do you know what race this is? This is a mutant that failed to advance to the Black Iron race. Do you even know what the Black Iron race is? They..."

Although Lin Feng didn't know either, that didn't stop him from exaggerating. He pointed at the black monsters mining and said, "Do you know their basic strength? Around 10 tons, stronger than a level 3 awakened being. They have high resistance, strong endurance, and are obedient. They're a natural-born bull-horse race. Moreover, their racial characteristics can even make the gray fog avoid them. If your caravan had one of these, the gray fog wouldn't swallow you up immediately..."

Old Chen: "I don't know what you mean by gray fog. Don't lie to me. In the ten days or so since we came here, apart from mutated creatures and strange things, we've never seen anything like what you're talking about."
