These days with God of Light, Green is not idle. Although he is not yet proficient in mastering the power of the source, he has reached a point where he can use it freely.

Since source energy cannot kill the virus, let the power of the source handle it.

The golden light slowly entered Elsa's body through Green's palm, and the power of the source quickly identified the culprit that caused Elsa to become like this, tearing apart all the virus bodies.

As the power of the source gradually flowed into Elsa's body, her complexion improved significantly. Her furrowed brow relaxed a little. Green's anxious heart finally settled.

"Elsa, do you feel better?"

Seeing that Elsa's complexion was much better than before, Green stopped using the power of the source. His golden hair quietly returned to black.

Feeling the warmth in her abdomen, Elsa's body gradually became more comfortable. After hearing Green's concerned inquiry, she slowly opened her eyes.

"Much better... thank you..."

"Whew..."

Relieved by this answer, Green let out a sigh, then hugged Elsa's upper body tightly.

"Do you know how scared I was just now? You are the granddaughter of the Demon King, you should act accordingly!"

Whether it was due to exhaustion or other reasons, Elsa didn't struggle while being held tightly by Green. She listened to his complaints without saying a word, only responding to his embrace by opening her arms.

After who knows how long, Green heard a steady breathing. He thought Elsa had fallen asleep, but when he tried to put her down, he realized that Elsa's grip had tightened.

Green immediately understood that Elsa was not asleep. He carefully thought back to the fact that she had not only been infused with source energy but also had the power of the source enter her body. In theory, she shouldn't be tired and want to sleep.

On the contrary, she should be full of energy.

"Green, I want to..."

"What do you want to do?"

Green swallowed his saliva, feeling a bit dry in the mouth for some reason.

Elsa blushed slightly, then forcefully pulled Green down and lay down with him.

And what happened next was not surprising to Green.

——Afterwards.

Elsa fell into a deep sleep, breathing peacefully.

Green put on his clothes and decided to go to the mortal realm to find Faelana.

When he used the power of the source to save Elsa, Green discovered something that ordinary people wouldn't notice. If his guess was correct, the reason why the demon realm had a widespread epidemic was most likely due to the demon realm itself.

If that was the case, the power of the source would be needed.

But Green couldn't use the power of the source to help all the demons recover. The power of the source was more than enough to deal with this disease, used on Elsa herself. However, using it on ordinary demons would be like using a cannon to kill a fly.

"Hopefully, Faelana will have good news."

Green gave one last look at Elsa, smiled faintly, and left the demon realm.

Thanks to the effectiveness of the potion, Faelana's mood has been exceptionally good these days, and she has shown more interest and energy in her research.

The potion that Faelana used for the patients who were on the verge of death was made by extracting substances from the flesh of the Black Dragon King, combining them with materials extracted from dragon scales, and adding various miscellaneous items through a special method. The cost was undeniably high.

Obviously, such high-cost potions cannot be mass-produced before the dragon scales are depleted.

Moreover, the effect of this thing is too strong. It would be a waste to use it casually for any illness.

Therefore, after removing the dragon scales, Faelana focused on studying the relatively abundant resources of black dragon king's meat, and quickly developed products targeting different groups of patients with low, medium, and high-level diseases.

This not only greatly reduces costs, but also allows people to get what they need.

The next step is to make it public and let it enter the market, but we still need to wait for Green to come back.

When Green returned from the demon realm, he immediately found Faelana.

Green appeared directly in front of Faelana and the pathway opened by the power of the source could accurately pinpoint the location without any error.

Faelana almost thought she was seeing a ghost, but luckily it was not a ghost, but Green.

Upon discovering that it was Green, Faelana immediately became excited.

She excitedly told Green about her research results and took out a few bottles of samples for Green to see. She was extremely excited and had expectations, naturally hoping to receive Green's approval.

And in the end, her wish came true.

Green was very satisfied with Faelana's achievements, even beyond expectations.

He couldn't help but marvel at her being the descendant of the healer's researcher.

At the same time, Faelana also showed Green the low, medium, and high-end products. The more Green saw, the more amazed he was. He never expected Faelana to be so outstanding, even the lowest-end product could instantly cure most minor illnesses.

Although there is also the magical aspect of the black dragon king's flesh, the fact that it can be extracted into medicine is enough to prove Faelana's strength.

Faelana quickly became an impressive figure in Green's mind.

After obtaining Green's permission, Faelana quickly released the three levels of products into the market. Although she didn't include the top-level product fused with dragon scales, the impact on the market goes without saying.

In short, because of this, the status of the Farcist Kingdom has been rising internationally and can be said to be the most powerful kingdom recognized by the public.

After taking most of the top-level medicine and coordinating with Aloof and others, Green returned to the demon realm again.

Because Green also told Aloof and others about the situation in the demon realm, they didn't stop Green, or rather, they didn't have the strength and it was also meaningless to stop him.

Not long after, Green returned to the demon realm again.

Elsa was already awake and had changed her clothes.

"How? Have you found a solution?"

Seeing Green's expression was very good, Elsa couldn't help but ask curiously.

Green didn't hide anything and took out the medicine he brought.

"The effect of this is almost as good as the universal potion I used before. I believe it can cure these sick demons. Then, we can trace the root cause and solve some things."

The potions Green obtained were quickly distributed, but the number of bottles was definitely not enough. However, even after dilution, they still had strong medicinal effects. At the same time, Green also added some source energy fused with the power of the demon king.

In this way, even patients with extremely weak bodies can instantly regain vitality after taking the medication.

Under the guard of the three former demon lords, the medication was smoothly distributed to each patient.

The conservative old man naturally received the medication freely provided by Green.

"Can this small bottle of potion really work?"

At first, several people were skeptical of the effect because they had never seen anything like this before, and medical science was not very advanced. Whether they could survive such a large-scale infectious disease depended entirely on luck.

Especially for those who were already approaching the twilight of their lives, they had long lost hope.

However, with a desperate attitude, they ultimately drank the potion.

In an instant, they felt a turbulent force surging through their bodies, causing their complexion to change, as if they had taken the wrong medicine.

The people around them wanted to come forward in concern, but they didn't know what to do and could only stand helplessly in place, while becoming increasingly resentful towards Green, who brought these medications.

Previously, they had no idea why Green wanted to transform the demon world, and now they didn't even know where these medications came from.

If members of the demon world were to perish because of this, they would never let this young and arrogant demon lord off easily.

But a miracle happened, immediately dispelling these thoughts.

Although they felt uncomfortable throughout their bodies after taking the medication, amidst the discomfort was a warm spring-like flow. It seemed that something was gradually being eliminated from their bodies, and the discomfort gradually dissipated, transforming into exhaustion.

But the miraculous thing happened next.

After the exhaustion appeared, a violent yet gentle energy immediately entered every cell of their bodies, sweeping away the exhaustion in just an instant.

The healed old man looked at his body unbelievably and even felt that his current physical condition was better than before the illness struck.

"Perhaps, this demon lord is far more capable than we imagined."

At that moment, he changed his attitude.

The other members of the conservative faction saw this scene and looked at each other, their eyes filled with disbelief.

It wasn't just the leader of the conservative faction, but also many of the other influential forces who were affected by this infectious disease. They were all treated with the cure brought by Green, treating everyone equally.

In the face of the medicine brought by Green, ordinary demon races drank it without hesitation and basically had no doubts.

But it was different for these major forces. Although they didn't dare to confront the demon lord, it didn't mean they fully trusted him. Even though Green had already proven his abilities through the teleportation gate, it had secretly caused dissatisfaction among certain forces.

After all, the demon lord only surpassed them on a biological level but couldn't interfere with their thoughts.

Just like the gods humans believe in, there are naturally those who don't believe in them.

These forces basically took a desperate approach and took the medication distributed by Green, hardly harboring much hope. Even if they saw someone recover after drinking it, they still remained skeptical.

It wasn't until the potion truly flowed into the patients' bodies and gradually restored their vitality that they changed their attitudes.

Those forces that had lost some benefits due to Green changing the teleportation gate also completely abandoned their objections.

In actuality, among the previous demon lords, there had never been one like Green who cared about the lives of ordinary demon races and even personally managed certain matters.

The previous portals were also launched after the passage of time by some forces.

It can be said that apart from being the Demon King in name, the Demon King's status is far higher than that of ordinary demons, and he simply does not interfere in the affairs of ordinary demons, let alone manage their life or death - except for his followers.

However, Green is different. Regardless of rank or nobility, he freely distributed medicine to everyone.

This has changed the perception of the Demon King among the people of the demon world.
