In Lin Jiangong's ward, the vital signs were moving at a slow but steady speed in a small mountain. The green light on the apparatus represented the patient who linked them, Lin Jiangong.

Sister Chi had already arrived beside Lin Xinnan, standing shoulder-to-shoulder with her. Maybe it was when Wang Xiaoyu summoned the Prosperous Demon Eye earlier, he had only glanced at her for a moment, before turning his head away. As a result, she simply did not see Wang Xiaoyu's pair of strange eyes.

Evidently, after Lin Yuyan passed out and was helped by Sister Chi to rest in another room, she had not woken up at all. This caused Wang Xiaoyu to have a huge regret in his perspective.

However, the current Wang Xiaoyu did not have the mind to care about that regret. After his Prosperous World Demon Eye ended, he already understood the crux of Lin Jiangong's illness, and he believed that all the questions would be directed towards that black ball of energy.

Then, what was this black ball of air?

Wang Xiaoyu could not bear to see this elder sister, he could only beg for guidance from the Fat Cat Demon Sovereign in his body once again.

"Demonic Lord, through the Golden Age Demon Eye, I found a strange black ball of air at the patient's heart. According to my calculations, this black ball of air is the root of the disease, look, this black ball of air is a god or devil!"

He spoke out his doubts, believing that with Fat Cat Demon Sovereign's strength, he should know that this was a godly thing.

Sure enough, before Wang Xiaoyu could even finish asking, Fat Cat Demon Sovereign shouted loudly, "I'll take a look, this, this is actually a f * cking demonic insect!"

"Demonic insects?"

Fat Cat Demon Sovereign's reaction gave Wang Xiaoyu a big fright. In his opinion, that black ball of air was just a ball of air, no matter how he looked at it, it didn't seem like a bug at all.

Therefore, he hurriedly asked: "Demonic Lord, that was clearly a lump of black air. No matter how I look at it, it doesn't look like a bug.

Just as he finished asking, the Fat Cat Demon Sovereign snorted coldly, and said slowly: "Hmph, slut, you f * cking know a ball, who the hell said that the demonic insects would definitely take the shape of a bug?"

"Hmm? Not in insect form? "Could it be?"

Wang Xiaoyu couldn't help but interject.

"This Demonic Lord hates people who are interrupted the most, can you listen to what this Demonic Lord has to say first?"

Seemingly, the Fat Cat Demon Sovereign was very dissatisfied with Wang Xiaoyu interrupting. After hearing its reprimanding of Wang Xiaoyu, he continued: "Qu Nian, listen carefully for this old man. The so-called demonic insect refers to a Demonic Cultivator or demon monster, use a special method to inject a certain amount of demonic power into a certain object!"

"Once these items are worn by humans, the demonic spiritual energy that is injected into them will be transferred to the human body!"

At this point, Wang Xiaoyu wanted to interrupt them to ask, but when he thought about Fat Cat Demon Sovereign's scolding, he resisted it in the end and focused on listening to what Fat Cat Demon Sovereign had to say next.

"Once this demonic energy is transferred to the human body, it will form a ball of air at a certain location in the human body. At the beginning, the ball of air was very small, and I estimate that it's only the size of a grain of rice.

"When it becomes the size of a ping pong ball, these balls of air will begin to shrink and condense, forming a space the size of a soybean in demonic energy. And this demonic insect will be born from this demonic energy space!"

After he finished speaking in a single breath, the Fat Cat Demon Sovereign took a glance at him and suddenly said: "You slut, do you understand?"

"I think … I probably understand it now!"

Wang Xiaoyu was afraid that the Fat Cat Demon Sovereign would scold him, hence he quickly replied.

But just as he said that, he remembered something. The ball of Qi in Lin Jiangong's body seemed to have already reached the size of a ping pong ball. If that happened, wouldn't it begin to shrink and condense?

And then the demonic insects were born?

"Oh my god, to give birth to a demonic insect in my body, just thinking about it makes me feel sick!"

When Wang Xiaoyu thought that the demonic insects would appear in his body later on, he felt goosebumps all over his body.

"Hmph, it's just a demonic bug, what's so scary about that!"

"Oh right, this Demonic Lord forgot to tell you just now, once these demonic insects are born, they will not continue drinking human blood essence!"

With regards to Wang Xiaoyu's goosebumps, Fat Cat Demon Sovereign felt a strong sense of disdain. It first snorted coldly, then said: "Although they won't continue to drink blood essence, they need a large amount of energy to change from the gaseous mass into their living form."

"Therefore, the insects at this stage can only rely on eating human organs as energy to grow fast!"

When Wang Xiaoyu heard that, he was so scared that his whole body was trembling. He quickly asked Fat Cat Demon Sovereign, "Demonic Lord, quickly help me check if there are any demonic insects in my body!"

Once he said that, the Fat Cat Demon Sovereign snorted coldly once more and said with disdain, "Hmph, with this Demonic Lord in your body, forget about mere demonic insects, even monsters with the power of the Demon Emperor can't even dream of approaching you!"

"Hehe, Demonic Lord is the best!"

Hearing this, Wang Xiaoyu's worries were finally relieved, but this also made him think of another question: "Demonic Lord, then where will the demonic insect go after eating its internal organs?"

"Most of the time, after these demonic insects eat a person's internal organs, they will break out from their heart and return to the monster that laid them on the ground. They will then refine and absorb them!"

The Fat Cat Demon Sovereign replied.

"Refining and absorbing?" Could it be to increase your demonic powers? "

Wang Xiaoyu pondered. Suddenly, he thought of the most crucial point that he had yet to ask, and said: "Demonic Lord, since this ball of air is a demonic insect, then quickly lend me some demonic energy. Let me exterminate it!"

Wang Xiaoyu felt that since the Goblin Bug was formed from a bit of demonic power, and associated with his own demonic powers being devoured by the Fat Cat Demon Sovereign just now, he naturally assumed that the demonic power was from the Fat Cat Demon Sovereign.

"Who knows …" Hmph, do you think these demonic insects are so easy to deal with? I, Demonic Lord, will tell you this: if this demonic insect had come out from the body, it would be easy to deal with. However, it is currently hidden in the human body, so it will not be an easy task. "

"Although this Demonic Lord's demonic energy can easily exterminate it, the demonic energy that exterminated it will also directly burst the meridians of ordinary people!"

Hearing Fat Cat Demon Sovereign's words, Wang Xiaoyu felt that this thing was not a simple thing.

"Then what should we do?"

Wang Xiaoyu asked anxiously, he did not want to spend so much effort to find the illness and leave it at that.

"Maybe other people would not be able to take care of it, but what kind of existence is this Demonic Lord? This Demonic Lord tells you that this Demonic Lord is the first person in the world of demon beasts who has taken a glance at me. He vowed to return to his peak strength, shatter the heavenly tribulation of the ninth level, and advance to the Demon Ancestor. "

Just as Wang Xiaoyu was about to take the opportunity to flatter his, Fat Cat Demon Sovereign continued, "So, a mere demonic insect, this Demonic Lord still has to use your Earth Realm's method!"

Wang Xiaoyu: "...!"

"Understand it. Pao Nian, let this noble one pass on to you the legacy of the ancient doctors of Earth — Monarch Demonic Scripture!"
