The Immortal of Plague begins by establishing the root of lung fire.

"Very good, please follow me." Another celibate disciple withdrew, leaving the one who had spoken to Song You earlier: "Honorable guest, my name is Atri. My patriarch has dedicated his life to Agni and follows the precept of not speaking outside the mouth. I will convey your words on his behalf."

"This is troublesome." Song You followed the two to the sacred bath. The figure of the Sect Master of the Era, wearing a wide red robe, appeared before him. He looked much the same as when they last met, still thin and hunched over.

Atri knelt down and woke the sect leader. After a brief conversation, the sect leader turned to Song You and nodded in greeting. Song You returned the greeting with his hands clasped together.

The sect leader cleared his throat twice and beckoned. Atri said to Song You, "The sect leader hopes you will come closer."

Song You observed the sect leader before him. He looked to be in his seventies or eighties, just an ordinary person with no trace of cultivation. Sensing this, Song You proceeded with peace of mind.

Upon getting closer, Song You could clearly see that he was plagued by numerous ailments. Even though Song You didn't believe in such things, he still had basic respect for someone who had dedicated his life to his cause: "Thank you for your hospitality these past few days, Sect Master. May I ask what brings you here?"

The sect leader spoke, his voice hoarse: "Honorable guest, your unwavering piety during the holy bath that day touched me. You are more outstanding than us in your test of Agni."

After listening to Atri's account, Song You said without changing his expression, "Sect Master, you flatter me."

He realized that everyone here was a devout fanatic who would attribute everything to Agni. He might be able to take advantage of this, since faith held a high status and was shrouded in mystery in India, which could provide him with cover.

Just as the sect leader was about to speak, he suddenly fell forward. Song You and Atri quickly caught him. Upon closer inspection, Song You could see that he was riddled with illnesses and that he had only managed to hold on until now thanks to sheer willpower.

Since it's not the sect leader's problem, the problem must be the Ganges River. It's likely that the other party noticed the changes a few years ago, but because of their faith in Agni's ability to purify diseases, they chose to personally oversee the situation.

After catching his breath, the sect leader said, "I'm sorry, my illness is incurable now, and I don't have much time left. I hope you can start learning Sanskrit and join me in making offerings to Agni. I will give you the most honorable position."

Song You felt it was time to make a move. The fact that the current sect leader valued him did not mean that the next one would do the same. The other party was currently under too much physical strain. If he were to take out the Lung-Clearing Powder, the effects of the immortal Dao within it might be effective.

Shaking his head, the apprentice Atri thought he was going to refuse and was about to persuade him when Song You spoke directly: "Sect Master, please do not tell anyone about what happens next, and please keep my existence a secret after this."

"Alright, I agree." After a moment's thought, the Sect Master of the Era agreed and dismissed Atri. Once Song You was alone, he sat down in front of the Sacred Pool and waited.

A moment later, the sect leader witnessed a scene he had never seen in his entire cultivation life. Song You's body began to tremble violently, and then his mouth opened wide, and he suddenly spat out a cloth bag. On the cloth bag, one could still vaguely see the flames that had just been extinguished.

That was definitely not a magic trick. He had seen countless impudent blasphemers show off in front of him, but none of them were as real as this. In addition, the other party had just asked him to keep his existence a secret, which was similar to Agni's cautious personality.

This was the reason why the gods sent messengers to punish him after he had been sitting in charge for so long without any improvement. The moment he realized this, his emotions poured out.

"Agini descend, Agini descend, messenger of the gods, forgive the servant's rudeness." The patriarch of the era was now crying like a child who had finally met his long-lost parents.

When Song You looked over, he saw the sect leader of the Era Sect lying in the holy bath, crying and shouting. He helped him up and picked up the fifth-grade low-level lung-clearing powder: "Sect leader, try taking this."

Song You carefully compared the levels of the two worlds. The medical level of the Huiguang World could barely cope with the initial lesions of the Po Cang Guan, but it was basically powerless against the initial attacks of Chai Xin. Whether he could survive depended entirely on how much ability Song You used.

The Lung-Clearing Powder can be effective for cultivators in the Firewood Stage, and it can easily prolong the sect leader's life in the short term.

The sect leader was completely numb. He took the lung-clearing powder and swallowed it in one gulp. A moment later, a cool sensation came from his chest, and then his entire lungs and internal organs were purified. Although he still had many illnesses, he felt much more relaxed.

"Thank you for the divine blessing," the sect leader said in fluent Eastern language.

Song You looked at him in surprise: "You can speak an Eastern language?"

"Gods have no form." The sect leader looked at Song You devoutly. "In preparation for the descent of the gods, I learned more than a dozen mortal languages, but I have never spoken any of them and have never broken the taboo against speaking them."

“Agni has sent an envoy from the East, so I cannot be rude to him.”

Learning more than a dozen languages ​​without even speaking them is incredibly difficult; only those who have tried it know how challenging it is. Song You admired his talent. Now, the other party regarded him as a messenger of a god, saving him a lot of trouble.

"In that case, please keep your promise. It would be best if I could stay by your side." After thinking it over, Song You decided that it would be best to stay by the sect leader's side so that he could keep an eye on him. Moreover, Song You found that he was more comfortable staying next to the Holy Bath.

The sect leader agreed: "As the divine envoy said, from now on your status will be that of a high-ranking cultivator of my holy land, and all your expenses will be provided by the holy land. May I ask the divine envoy what exactly is wrong with the holy water?"

Song You thought of the industrial area he had passed through earlier, but he was unsure whether Xiangti Kunji had the ability to withstand the opponent, so he decided to observe for the time being: "I have a plan for this matter. What you need to do now is leave the holy water to recover your health and better make offerings to Agni."

After hearing what Song You said, the sect leader finally left the sacred bath and felt much more relaxed. He then called Atri to help Song You change his clothes.

Song You changed into a double-layered shawl and draped a gold-edged shawl with scriptures on it, feeling the softness on his body. The holy land had specially prepared a temporary residence for the two of them, with each of them having a single room.

After everything was arranged, this place could provide him with supplies for a long time. Song You ate another meal, and the scene before him shattered. Song You returned to the Soul Treasury Temple.

The familiar chilling aura of the Soul Treasury Temple filled Song You with a long breath. His body felt refreshed and ready to continue practicing. Now that the time was up, he only needed to increase the quantity as well, and he would have enough time to complete the task.

Song You restarted the furnace and added the medicinal herbs one by one. Learning from his previous experience, Song You controlled the process more precisely and had a more accurate perception of the temperature of the coal, enabling him to use the mechanism to adjust the temperature to the perfect level.

Finally, Song You had an idea. He added half an ounce of yellow earth to condense the powder, extinguished the furnace fire, and there were now five piles of medicinal powder underneath.

There's even hidden knowledge in the book.
