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

The man glanced back at the direction of his convoy, where more than a dozen vehicles were parked, their occupants waiting for food to save their lives.

"Then I want 100 jin of potatoes, 200 jin of potatoes, and 20 jin of cabbage..."

He quickly did a mental calculation and handed over the strange crystal in his hand.

After putting away the strange crystal, the girl quickly made a note in her notebook, then tore off a piece of paper. She then waved behind her, and a young man quickly walked over, took the paper from her, and gestured to him.

"Come with me, I'll take you upstairs to pick up the goods."

The captains of the other small car teams took out the mysterious crystals from their pockets one after another and chose their items.

Someone at another stall saw several other items and asked, "What are these? Why are they so expensive?"

Seeing that someone was interested in the items, the girl introduced them: "These are black iron-grade foods cultivated in our Xuanfeng City. This red heart fruit can enhance mental power. After being cultivated by the Creation Spring and professionals, it is still effective even for people above level 4. One fruit is worth one level 2 ghost crystal."

"And this gray wheat, which is a mutation of gray-faced spike grass, can improve physical fitness. One pound of gray wheat is worth one level 3 ghost crystal."

They stared at the two items for a long time, then asked, "Can these things really improve mental strength and physical constitution?"

The girl still had a smile on her face: "Of course, this is a high-quality food personally cultivated by a level 4 professional, Lady Xiaoli. This kind of thing is in short supply in Xuanfeng City. You are lucky to have come across it. It is a limited supply."

One of them hesitated for a moment, then took out 10 Level 2 Mystic Crystals from his pocket: "Give me 10 Red Heart Fruits."

After receiving the red heart fruit, he immediately put one in his mouth. He first felt the long-lost sweetness, then his mind felt cool, and his mental strength increased by one level.

"Holy crap, this really does enhance mental power! I feel like my fire manipulation skills are much more agile now..."

"I also want 1 pound of that gray wheat. Can I pay with a level 2 Mystic Crystal?"

"Yes, low-level monster crystals can be exchanged for high-level monster crystals at a ratio of 1:15, with an additional fee of 5 crystals."

"Oh, there are extra fees?"

"Of course. You can kill a level 2 monster, but can you kill a level 3 one? High-level monster crystals also have the function of helping people break through their cultivation levels. Although we in Xuanfeng City basically don't rely on monster crystals for leveling up anymore, their value is undeniable. Are you willing to trade?"

"Change, change, change..."

Seeing that it was effective, the others all reached into their pockets. They could go hungry for a couple of days if they didn't have any food, but improving their strength was something they had to do immediately. Every bit of strength they gained meant a bit more safety. Maybe next time they faced something strange, they would be just a little bit stronger.

These kinds of transactions happen every day the convoy stops, continuing until the convoy sets off again.

Not only those in small caravans would come to trade, but also those in need from the outer city, because it wasn't just food, but also weapons.

These weapons range from ordinary mortal weapons to black iron grade weapons.

The sale of the first batch of Iron-class weapons, in particular, caused quite a stir.

The black iron daggers, longswords, and spears crafted by the Forge Princess are extremely popular.

These weapons are forged from black iron, with incredibly sharp blades that can pierce through a 10-centimeter steel plate with a single thrust. They cut through iron like mud, and ordinary mutated beasts are powerless against them. A single slash can sever their heads, and even the toughest scales cannot withstand the attack of these black iron weapons.

Especially black iron weapons infused with materials dropped by mutated beasts or monsters can not only deal with mutated beasts, but also inflict extra damage on monsters. Even ordinary people wielding such weapons can kill monsters unexpectedly.

The only price is that it drains a person's vital energy; if used too much, it will turn them into a dried-up corpse.

Ideally, it should be used by all professions, and one should also eat more mutated beasts and foods that can improve attributes.

Few people could afford it. A convoy of about 500 people sent someone to inquire about the exchange price of the black iron-grade weapon. The person was a woman with short hair and a short knife made of animal teeth tucked into her waistband. Her gaze lingered on the black iron short knife for a moment, then she picked it up and asked.

"How do we replace this knife?"

Seeing this, the girl behind the stall immediately perked up and introduced, "Sister, this is a Black Iron grade short sword. It's made entirely of black iron ore fused with strange materials. It can damage strange creatures of level 4 and above. The price is 20 level 4 strange crystals, but it can also be traded for other resources, such as mutated beast materials, rare items, and strange creature drops..."

The woman caressed the dagger with obvious affection, remaining silent for a long time before finally pulling a bag from her waist and handing it to him: "I want one..."

The girl behind the stall quickly counted the items and handed the bags back.

With the appearance of these weapons, the entire convoy was caught up in a frenzy of collecting Ghost Crystals to buy them. It turned out that the main reason why the strange creatures were so difficult to deal with and the mutated beasts so hard to kill was that only Awakened Ones had the means to harm them.

Now, as long as they have weapons, ordinary people can deal damage, not to mention that they have gained professions, and killing monsters is a way to gain experience.

It's like they're showing their health bars to ordinary people too.

The mutated beasts along the way were completely out of luck. They used to charge at the convoy whenever they saw it, treating it like a delicious human meat bun.

Now, if you see a convoy in the distance, run as far away as you can. As for those who don't escape... they'll either end up in a pot or become sacrifices.

Some people have been saying privately that Lin Feng shouldn't activate his protective domain when he rests at night, as there aren't enough eerie creatures around to kill...

Just then, Lin Feng was inspecting the installation of the 10 newly manufactured crossbows when shouts came from below the city wall.

"Lord City Lord, could you please not activate the protective domain tonight? Your ant swarm has wiped out all the mutated beasts and monsters around here, and we also want to increase our strength..."

"That's right. Although our profession isn't particularly powerful, we're still professionals, and we need to earn Ghost Crystals too."

"Yes, we also want to obtain resources..."

Seeing those people shouting that they wanted to kill the monster, their emotions running high.

Lin Feng turned to look at Wang Lie: "Are all your men this brave?"

Wang Lie remained noncommittal: "Their progress in strength has indeed been a bit slow lately. Should we give them a chance?"

What could Lin Feng do in response to such a request? Of course, he had to satisfy them.

"Alright, the protective zone won't be activated tonight. Those who want to kill monsters to improve their strength, grab your weapons now, you can leave the city..."

As soon as Lin Feng finished speaking, a cheer erupted from below.

The patrolmen, weapons in hand, marched out in groups, boarded their chariots, adjusted the crossbows on the roofs, and began to set up defensive formations around the area.

Some of the bolder life professions even followed Wang Lie and his group out of the city gate with some ordinary-level weapons. Those weapons were all made by low-level blacksmithing life professions. They were okay for dealing with low-level monsters, but against level 3 or 4 monsters, they were practically asking for death.
