While the ingredients of mushroom powder are uncertain, bone meal is certainly an important ingredient.

"What's bone meal for? To supplement calcium for saplings?" Zhang Xiaojuan scratched her head, looking confused. "But when I was little, my grandma would often put eggshells and soybean cakes in the soil when she planted flowers, saying that it would make them grow faster."

"But isn't that factory using human bones...? Which one do you want to kill randomly?" Zhang Xiaojuan sat up straight nervously.

Xu Yi chuckled, "The composition of zombie bones is similar to that of human bones, so human bones are not necessarily required."

"It's probably the same principle as people taking calcium supplements." Zhang Xiaojuan thought it made more and more sense, and immediately stood up, rubbing her hands together eagerly. "Then what are we waiting for? Let's go out and fight zombies!"

Zhao Mujia dragged his aching thighs to his feet. "Brother Juan, don't be in such a hurry. The zombies outside are hard to deal with right now. Let's at least prepare before we go."

Due to high temperatures and water scarcity, coupled with the ever-expanding desertification, the zombies in the outside world have undergone a second mutation in just two months.

Apart from some high-level zombies that have developed some self-awareness, the remaining zombies are all a new type of zombie that is shriveled and charred.

These zombies were shriveled and hardened from dehydration, their charred skin tightly wrapped around their bones like a thin film.

Due to their hard shells, these zombies are extremely resistant to blows, and it is difficult for ordinary melee weapons to damage their skin.

Although the number of surviving new zombies has decreased, their combat power is at least twice that of the previous ordinary zombies.

The living people nearby are mostly clustered in the safe zone, and the zombies are running out of food, leading to a growing trend of cannibalism. This has resulted in a dramatic increase in the number of mutated zombies that trigger the devouring condition.

The danger of hunting zombies has increased exponentially, and most people can only cooperate in groups. Zombie hunters who go it alone can hardly make any progress.

“Everyone’s been exhausted from planting trees all this time, they need to rest for at least a day or two.” Su Zheng also supported Zhao Mujia’s opinion.

Fighting while fatigued is too dangerous, and a day or two won't make a difference.

“We don’t need to do it ourselves this time.” Lu Sheng thought for a moment. “We can post a notice outside the safe zone that a zombie with a complete skeleton can be exchanged for half a pound of rice or two ounces of meat, with no limit on the quantity purchased.”

What should you do after accumulating capital? The answer is to use the least amount of resources to obtain the greatest value!

Now those little devils and white people outside are starving and emaciated, even fighting over insect meat. As a wealthy and powerful nouveau riche, how can she not make good use of them?

“Emm…” Zhang Xiaojuan hesitated, “Sister Lu, aren’t you being a little too dark?”

"No merchant is without guile."

Lu Sheng responded very frankly.

Back then, those white people and little devils took advantage of their technological superiority to gain a lot of benefits for the country. She's just now collecting a tiny bit of interest for her predecessors.

After Lu Sheng issued the announcement, several foreign camps on the outskirts of the safe zone were in an uproar. That very night, many people took weapons and tools and went in groups to find zombies.

It's important to understand that resources are extremely scarce now, making survival much more difficult than in the early days of the apocalypse.

The crystal cores they now possess are practically useless, as few people are willing to sell their limited resources.

Lu Sheng, being wealthy and generous, directly traded zombies for rice and meat, which was no different from a windfall for these people.

Money can make the devil turn the millstone, and meat can make people kill corpses.

Just one day after the announcement was issued, long lines formed at the entrance to the safe zone as people came to exchange for supplies.

At first, these people were unsure of themselves and were just testing the waters, so they didn't hunt many zombies, usually only one or two per small group.

Even though there were only one or two, these people were covered in wounds, clearly indicating that the hunt was not easy.

Ma Dongmei and Lin Xiaobao set up a table at the entrance; one collected zombies, and the other was responsible for exchanging supplies.

"With zombies so hard to kill these days, isn't giving us only half a pound of rice or two ounces of meat too little?"

At the head of the group was a tall, burly man named Xiao Xiba, who was negotiating with Ma Dongmei in somewhat broken Mandarin.

"If you think it's not enough, keep it for yourself." Ma Dongmei said, a cigarette dangling from her lips, as she crossed her legs and placed them on the edge of the table.

"We're risking our lives to kill zombies, and you expect us to fight like this for such a small amount?" the man retorted, slamming a shriveled zombie onto the table.
