In the time-traveler chat group, am I the only one on Earth?

"So, you agreed?"

"How could I refuse? But only if your son is still alive."

Lu Yun's answer was very decisive.

There are many intractable diseases in this world, and quite a few wealthy people have been diagnosed with leukemia.

If I could cure leukemia, making money would be a piece of cake.

So... setting aside all other rewards, this method of treating leukemia alone is worth a fortune!

"Of course, I'll give you the method for treating leukemia. You can study it first, and I'll give you my son's information later."

OK!

After ending his conversation with Lin Chen, a new task appeared in Lu Yun's personal task list.

[The Divine Doctor's Concern—To find Lin Chen's son, 'Lin Xiaohao,' on Earth, and gain the trust of Lin Chen's wife, Shen Weiwei, in order to alleviate Lin Xiaohao's leukemia symptoms.]

[Task completion reward: 1000 group points.]

[Note: Since this is your first time triggering this group member's quest, you will receive an additional reward upon completion: Lin Chen Ability Card *1.]

..........

There were three time travelers in the chat group, and they triggered two missions in a row.

Needless to say, the remaining Su Chen must also have a mission.

However, Lu Yun was not in a hurry. He first clicked to sign in on the chat group's sign-in interface and earned 10 points.

Then, after glancing at the information sent by Li Susu, he finally found Su Chen.

After some investigation, Lu Yun learned about Su Chen's tragic life.

Why is Su Chen's life considered tragic?

Compared to the other two transmigrators, Su Chen's life was truly difficult.

Although Lin Chen transmigrated, the world he transmigrated to was a novel with an urban setting.

Not only does he have convenient access to food, clothing, shelter, and transportation, but he has also transmigrated into the body of the protagonist, a divine doctor, in this novel.

With his exceptional medical skills and formidable combat prowess, this son-in-law, a divine physician, could easily thrive in that world.

Although Li Susu was just a woman and her time travel to the era of cold weapons was not very convenient, at least she lived in the palace and did not have to suffer from hunger and cold every day.

But this Su Chen... transmigrated to a post-apocalyptic world where resources were scarce.

In that world, humanity had long lost its dominant position. He was starving every day and had to fight zombies and mutated beasts as soon as he opened his eyes, which was extremely painful.

As for his task? It's not troublesome. He just needs to visit his parents and say a few words to them.

The task reward is the same as Li Susu's, 500 points, but the extra reward has changed from 'Li Susu Ability Card' to 'Su Chen Ability Card'.

"Come on, brother, this is what you deserve."

Su Chen readily sent a private red envelope.

The three time travelers were unaware that Lu Yun could trigger group member missions through them, so they received all the due rewards.

I opened the red envelope sent by Su Chen.

[Ding! You have received a red envelope (Gene Enhancement Potion *1) from Su Chen, a transmigrator from the post-apocalyptic world.]

[Ding! You have acquired an item from another world. The item will be automatically stored in the chat group's inventory system. You can use the 'Extract' function to retrieve the item to the real world.]

[Note: Private red envelopes can only be sent once per day. Items that have been transferred to the real world cannot be put back into the inventory system, but can be gifted to other group members.]

The chat group's inventory system is similar to the game's inventory, with 128 slots, each of which can hold one type of item.

As long as the item sent by the other party is no larger than the size of a truck, it can be received in this slot.

Although the same items cannot be placed in the same slot, they can be placed in a container.

For example, one grain of rice occupies one grid, and a bowl of rice also occupies one grid.

The same applies to an apple and a bag of apples, a bag of pears and a cartload of pears.

Looking at the backpack system, Lu Yun noticed a potion lying quietly, glowing with blue light, and felt a sense of curiosity.

"Gene enhancement serum? This thing can really enhance genes?"

Su Chen: "Of course, this is the capital that the humans of this world use to fight against zombies and mutated beasts..."

With Su Chen's explanation, Lu Yun gained a general understanding of Su Chen's world.

The world Su Chen transmigrated to was a wasteland.

That world was much larger than Earth, with the ocean making up less than 50% of it, yet it had a population of over 30 billion.

Although only 50% of humans turned into zombies in the early stages of the apocalypse, animals and zombies could evolve, but the remaining humans could not.

Therefore, if humanity wants to survive, the only option is to unite and unleash nuclear bombs on the monsters.

But no one expected that the nuclear bombs that humanity is so proud of have a very limited blast radius. The so-called nuclear radiation can only kill less than 30% of species, while the other 70% have the ability to resist nuclear radiation.

Coupled with the collapse of electricity and transportation, the human population is dwindling.

After a long period of darkness, when humanity was on the verge of extinction under the dual blows of nuclear bombs and monsters, gene-based drugs were developed by scientists.

Gene therapy is a very precious thing.

Not only can it resist zombies and various viruses, it can also greatly improve a person's physical fitness, turning them into a super soldier like Captain America.

It was the emergence of gene-editing agents that gave humanity hope for survival in this wasteland.

As for Su Chen, although he has only been in the world for a little over a year, the advantages of being a transmigrator are still there.

His rapid rise to prominence quickly earned him the organization's trust; otherwise, even if he were a transmigrator, he wouldn't have been able to possess extra gene-enhancing drugs.

"Are gene-editing agents really that powerful? Won't they have any side effects?"

Lu Yun muttered something to himself.

Chapter 5 Treatment of Leukemia

Although the chat group is real, and the group members are very generous,

But he and Su Chen had only just met.

Gene therapy drugs are medications that need to be taken orally or injected to be effective.

Lu Yun had to be careful about something that needed to enter his body. What if he turned into a zombie instead of becoming a muscular man?

"Don't worry about that. The gene enhancement drug I gave you might cause a little pain when you use it, but there are absolutely no other side effects or limitations. If you don't believe me, you can check it through the backpack system!"

Su Chen had the same thought when he used the gene serum, so he completely understood Lu Yun's concerns.

Upon hearing Su Chen's words, Lu Yun realized that placing his hand on the gene enhancement potion icon in the backpack system would display a line of text.

The label does indeed list the conditions for use and effects of this medication, and apart from some pain, there are no other side effects mentioned.

"Alright then, if you don't remember your parents' phone number, just give me their address. I'll go find them after I'm done with these last couple of days."

"Brother, wait a minute."

"Is there anything else???"

"To be honest, I've been in this world for over a year, and every day I eat the meat of mutated beasts and some wild vegetables and fruits!"

Su Chen was a little embarrassed: "Although these things are full of energy, they are really hard to eat, so... could you send me some food? I've been wanting to eat the food from our planet Earth for a long time."

In the wasteland world where Su Chen lived, there were many things that were lacking.

The most lacking things are clean water and fresh fruits and vegetables.

In the wasteland world where transportation is inconvenient and everyone lives in fear, these things are especially rare.

Su Chen, who traveled from Earth, would drool whenever he thought of Earth's junk food like fried chicken and cola.

Lu Yun had no reason to disagree with this request.

"That's a good idea. Wait for my news."

"Okay, thanks, bro!"

.........

After ending the call with Su Chen, Lin Chen also sent over the formula for treating leukemia.

Lu Yun glanced at it and saw it was a brown paper tote bag.

Lu Yun couldn't possibly retrieve items from the street, so he didn't know what was inside. Lin Chen promptly sent a message to explain.

"Inside are three parchments and an acupuncture kit. Two of the parchments contain prescriptions, and one contains a diagram of acupuncture points!"

"You don't need to study the prescription; just go to the pharmacy to get the medicine according to the prescription. What you need to study most is the acupuncture technique..."

Lu Yun nodded slightly.

He wasn't a medical student, so there were some things he didn't quite understand, but he still grasped the key information.

Both prescriptions are traditional Chinese medicine formulas.

One is used to inhibit leukemia. As long as the medicinal ingredients are combined according to the instructions, the resulting decoction can inhibit the spread of cancer cells and alleviate the suffering of leukemia patients.

The other one is for soaking silver needles.

Only by using soaked silver needles to perform acupuncture on leukemia patients can leukemia be completely cured.

Traditional Chinese medicine inhibits, while acupuncture cures?

Lu Yun: "I understand the general meaning, but there is one question I don't quite understand."

Lin Chen: "What's the problem?"

Lu Yun: "Since all the medicinal ingredients in your prescription are found on Earth, why haven't other experts been able to figure it out?"

Lin Chen: "I don't know about that, but with traditional Chinese medicine, inheritance is the key. Once a prescription is lost, it is very difficult to recreate it. The medicinal properties of Chinese herbs are also complementary. Sometimes, a little more or a little less will not have the desired effect."

"It seems...that makes sense."

Lu Yun seemed to be deep in thought.

"135XXXXXXXX, this is my wife's contact information. Please contact her as soon as possible. If my son is still alive, I hope you can use the first prescription to help alleviate his condition."

"Ok!"
