Mo Wuji didn't answer, he guessed he had walked into a trap, and he didn't want to say anything casually before understanding the nature of this trap.

His divine sense landed on the rental agreement he had signed with the white-bearded old man. The rental agreement was very clear: as long as his place was a medical clinic and had the name "No Sickness Clinic" hanging outside, he wouldn't be in breach of contract. Who said a medical clinic couldn't refine pills and do other things?

When Mo Wuji's divine sense landed on the rental jade slip contract again, he was stunned. After the phrase "to open a medical clinic," several more lines had been added to the contract: "No Sickness Clinic is a property of the Ao family. Renting this clinic must abide by the following conditions: This clinic must be a medical clinic. Second, on the seventeenth of each month, one bowl of Vitality Soup must be provided to the Ao family free of charge. The ingredients and methods for making the Vitality Soup are as follows: Level 5 Divine Spirit Herb Overflow Root, Level 5 Divine Spirit Herb Wave Flame Bamboo, Level 5 Divine Spirit Fruit True Sprout…"

Everything after "Second" had been added.

After reading the ingredients for this Vitality Soup, Mo Wuji took a deep breath. Whether in the God Realm or the God Continent, Level 5 Divine Spirit Herbs were top-tier. Due to the restrictions of the laws of heaven and earth, Level 6 Divine Spirit Herbs were very rare in the God Realm or the God Continent, almost non-existent.

And in this medicinal soup, there were six Level 5 Divine Spirit Herbs, twelve Level 4 Divine Spirit Herbs, and eighteen Level 3 Divine Spirit Herbs. Even if he sold himself, he couldn't come up with so many high-level Divine Spirit Herbs. If he had Level 5 Divine Spirit Herbs, he would have already started learning how to refine Level 5 Divine Pills.

That old bastard had set such a big trap for him, taking advantage of the fact that his divine sense couldn't see the hidden clauses in the contract.

At this moment, Mo Wuji was certain that the white-bearded old man was a God King.

"I never thought Old Xin could sublet this shop; truly remarkable," the Heavenly God official said with a hearty laugh when he saw that Mo Wuji hadn't answered.

Mo Wuji's heart sank. The white-bearded old man, a God King, had to provide a bowl of Vitality Soup to the Ao family every month. He, a small Nurturing God, probably wasn't even worth their breath.

The seventeenth of each month... today was already the thirteenth, so in four days, the Ao family would come to collect the Vitality Soup.

"Who said this isn't a medical clinic? Open your eyes and look at the sign outside; does it say 'No Sickness Clinic' or not? If there's nothing else, please leave; I have patients to see," Mo Wuji said coldly.

He was wary of the Ao family, who even the white-bearded old man feared, but that didn't mean he needed to be afraid of a small Heavenly God official.

"You have guts. I'll tell them that the shop has changed hands. Maybe they'll come early to collect the rent," the Heavenly God cultivator originally only wanted to extort some money from Mo Wuji, but he didn't expect Mo Wuji to ignore him, which made him furious.

"Get out," Mo Wuji rebuked without hesitation.

He wished this official would convict him and then banish him from Lingxiao City.

This official was clearly not an idiot; he only said coldly, "I'll leave. I'll come back in a few days to watch the fun."

Having said that, he really turned and left. If any other shop dared to treat him like this, he would have arrested them long ago. But he didn't dare to touch the people of the No Sickness Clinic; if something went wrong and they blamed him, he wouldn't have enough lives to pay for it.

"Master," Shuaiguo felt that something was not right.

Mo Wuji waved his hand, stopping Shuaiguo from speaking, and then said to the young man who had brought the old woman for treatment, "Bring the patient in, and I'll take a look."

"Yes, yes," the young man quickly helped the old woman into Mo Wuji's shop.

Mo Wuji was still thinking about the jade slip contract, and casually said to the old woman, "Sit down; let me take your pulse."

Mo Wuji wasn't very proficient in medicine. The medicine of the cultivation world was completely different from that of ordinary people. Therefore, even if Mo Wuji hadn't studied medicine, he possessed the Life Meridian and could still do many things that others couldn't.

When a wisp of Mo Wuji's divine sense penetrated into the old woman's spiritual meridian, he was shocked. This old woman was actually a World God powerhouse.

When did powerhouses become so numerous? The white-bearded old man who had cheated him earlier was a God King, and now a random patient he received was also a World God?

Soon, Mo Wuji found the cause of the illness. Even though he hadn't studied medicine, the old woman's illness was very simple: spiritual meridian necrosis, bloodline withering, and primordial spirit collapsing.

"Senior Physician, please tell me about my sister's illness…" the young man looked at Mo Wuji anxiously.

Mo Wuji didn't seem to hear the young man's words; he thought of the Sea of Silence.

Being invaded by the water of the Sea of Silence resulted in exactly this situation, didn't it? He cultivated the Mortal Dao, and had no spiritual roots or spiritual meridians, so he wouldn't be eroded by the water of the Sea of Silence.

Just because he could resist the erosion of the water of the Sea of Silence didn't mean he could treat patients who had been eroded by it.

Mo Wuji was about to shake his head when he suddenly thought that since this young man had been wandering around with this old woman for so long without her dying, it meant that the young man must have a way.

"Right, what were you saying just now?" Mo Wuji came back to his senses, and before the young man could answer, he remembered the young man's words, "This is your sister?"

"Yes, Senior Physician, this is my sister. Please, Senior Physician, how is my sister's condition?" the young man asked cautiously, afraid that Mo Wuji would say something that meant she couldn't be saved.

Mo Wuji thought to himself how powerful the Sea of Silence was. Since this old woman was the young man's sister, it meant that their ages were similar. Now, having her bloodline and spiritual meridians corroded by the Sea of Silence, she had aged so much.

"Answer a few questions for me first. Your sister should have been corroded by the water of the Sea of Silence, right? Contact with the water of the Sea of Silence means instant death; why is your sister still alive?" Mo Wuji asked doubtfully.

Although he was asking the young man, his gaze was on the old woman.

The young man quickly said, "My sister can't speak anymore. The main reason is that I obtained a pill formula. Unfortunately, I can't find a Pill Refiner to refine this pill, so I can only use a simplified method, using Silence Dao Sand soaked in water for my sister to drink."

"Pill formula?" Mo Wuji was shocked. There was a pill formula that could resolve the corrosion of the Sea of Silence?

Mo Wuji really wanted to see that pill formula; at least, there was no such pill formula in the jade slip of Qingyi God Pill King. But he knew that it was impolite; the value of such a pill formula was absolutely unparalleled, how could he just casually take it out for him to see?

"Master Physician, I'll show you the pill formula." Before Mo Wuji could ask, the young man fearlessly took out a leather scroll from his ring.

Mo Wuji saw a trace of anxiety in the old woman's eyes. If she could speak, she would definitely stop her younger brother from taking out this pill formula.

But her younger brother was obviously desperate, which was why he took out the pill formula.

Mo Wuji clasped his fists at the old woman and said, "Senior Sister, please rest assured, if I can refine a pill to save you, just because I've seen this pill formula, I will refine it for you for free."

The old woman seemed to know that she couldn't stop Mo Wuji, so she could only helplessly close her eyes and return to her state of near-death.

Mo Wuji opened the leather scroll. The first three words that caught his eye were "Silence God Pill" (Ji Shen Dan).

The Silence God Pill was a Level 5 Divine Pill. The main Divine Spirit Herbs were three, and the auxiliary Divine Spirit Herbs numbered in the dozens. The main Divine Spirit Herbs were purple Silence Dao Sand (Ji Dao Sha), Five-Vein Shattered Fruit (Wu Wen Sui Guo), and Frost Transformation Lotus (Hua Shuang Lian), all of which were Level 5 Divine Spirit Herbs.

Mo Wuji quickly took out the jade slip introducing Divine Spirit Herbs from Qingyi God King, and found the introduction to Level 5 Divine Spirit Herbs. He hadn't started to break through to Level 5 Divine Pill King yet, so Qingyi God King's introduction to Divine Spirit Herbs only went up to Level 4.

Now, as soon as he opened it, he easily found the introductions to Five-Vein Shattered Fruit and Frost Transformation Lotus. What attracted Mo Wuji the most was the Silence Dao Sand.

Silence Dao Sand was the sand formed by the condensation of Dao runes at the bottom of the Sea of Silence. After removing the Dao spots on the surface of this sand, it could allow cultivators to comprehend deeper levels of Dao concepts. Purple Silence Dao Sand could even allow people to enter the realm of God King through comprehending these Dao concepts of heaven and earth.

Mo Wuji hadn't expected that the pile of stones he had casually picked up at the bottom of the sea back then had such value. Although he didn't care about this kind of comprehension value, this thing was valuable. If he had known that Silence Dao Sand was so valuable, he would definitely have picked up more of it.

What shocked Mo Wuji the most was learning from the pill formula given by this young man that Silence Dao Sand could be used to refine the Silence God Pill. The Silence God Pill could actually repair cultivators' necrotic spiritual roots and spiritual meridians, and could also repair collapsing primordial spirits and stabilize bloodlines.

For Mo Wuji, this effect was more than ten thousand times more powerful than comprehending Dao rhymes and rules. If he wanted to enter the God King realm, he definitely wouldn't go to comprehend other people's Dao rhymes and rules.

Seeing that Mo Wuji's expression was uncertain and he didn't speak for a long time, the young man said uneasily, "Senior Physician, there is also a method at the end of this pill formula that can temporarily preserve the vitality of those with necrotic spiritual roots. My sister happened to find a piece of purple Silence Dao Sand. I have no way to find a Level 5 God Pill King, so I can only use it to soak in water…"

Mo Wuji had already seen the back of the pill formula, which did introduce that adding a few medicinal herbs to purple Silence Dao Sand soaked in water could delay the life of those with necrotic spiritual roots and withered bloodlines.

Mo Wuji already understood somewhat that this old woman definitely wanted to use the Silence Dao Sand to break through to the God King realm. As a result, she was lucky enough to pick up a piece of purple Silence Dao Sand. Unfortunately, she herself was also corroded by the Dao runes of the water of the Sea of Silence.

As a result, her younger brother used this Silence Dao Sand to soak in water, but still couldn't save her life. The gains and losses were really hard to say.

Thinking of this, Mo Wuji handed the pill formula to the young man and said slowly, "It's very difficult to cure your sister's illness. You must use the Silence Dao Pill. However, I can't refine the Silence God Pill yet. I do have a method. If it's successful, there's a small chance that I can save your sister. But the possibility of failure with this method is very high."

The young man knelt on the ground with a thud, "Senior Physician, I'm desperate now. As long as you can save my sister, even if I die, I'll be willing."

Mo Wuji reached out and pulled the young man up, sighing, "This method not only concerns your safety, but also my safety. If you have nowhere to go, just stay here. I need to go into seclusion for three days."
